Educating girls quite possibly harvests a higher rate of benefit than any other investment available in the developing world. Women’s education may be an unusual field for economists, but increasing women’s contribution to development is actually as much an economic as a social issue. And economics, with its focus on rewards, provides an explanation for why so many girls are deprived of(剥夺)an education.
Parents in low-income countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else’s family and bear children. Girls are thus seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school — the predict becomes self-ffulfilling, trapping women in a vicious circle (恶性循环) of neglect.
An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters and sons are given fair chances. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educated and healthy. The vicious circle is thus transformed into a virtuous circle(良性循环).
Few will argue that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 per cent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant impact on health practices, including family planning.

How to Avoid Weight Gain Over Holidays
Do you love the holidays, but hate the pounds that follow? You are not alone. Holidays are times for feasting and celebrating. Many people are worried about their weight. ______1______ Whether you are celebrating at the office party or sitting down for the traditional family dinner, regard eating as a time for tasting a variety of foods. The idea is to enjoy the holidays but not to eat too much. You don’t have to turn away from the foods that you enjoy.
Here are some tips for preventing weight gain and maintaining physical fitness:
Don’t skip meals.

Control portions.
Use a small plate (about 10 inches) and put aside the large ones that may encourage you to “load up.” ______3______ Once you have your “tasting” serving, move away from the dining table. Doing so will make it less tempting (吸引人的) to be eating constantly as your appetite is inspired by the sight of food.
Begin with soup and fruit or vegetables.
Fill up beforehand with water-based soup and raw fruit or vegetables. Or drink a large glass of water before you eat to help you feel full.
Stick to physical activity.
______4______ A 20-minute walk after a meal can help burn off additional calories.
______5______
Dishes that look oily or creamy may have a large amount of fat. Choose lean meats. Fill your plate with salad and green vegetables. Use lemon juice instead of dressing or butter.

F. Don’t let exercise take a break during the holidays.
G. You’d better remember the Dos and Don’ts for keeping fit and slim.
Public speaking is a common cause of stress for everyone. The idea of standing in front of a large group with all eyes on you can make you feel fearful in almost all kinds of situation, for example giving a presentation in class, proposing a toast at dinner or making a work-related presentation. It seems to be a fear that’s impossible to overcome. If you have ever experienced this, you know while the anxiety may develop at the actual event, it is a feeling that begins much earlier than the actual day. There are many ways you can work on your confidence and prepare yourself for a public speaking event.
A consultant specializing (专门研究) in presentation skills can help you to overcome your sense of panic. Working with a consultant does not indicate that you have a major problem; it is only an approach to receiving guidance on relaxation strategies, such as deep breathing, which can help you deal with public speaking problems with ease.
Consultants can also help you work on your confidence. Confidence is extremely important in public speaking as it lets a speaker sound more convincing. Even well-established public speakers practice techniques such as meditation (沉思冥想) to calm themselves before a public appearance.
It’s well worth the time and effort to overcome the fear of public speaking, particularly if talks and presentations are part of your work description. Keep in mind that many of those around you are also struggling with this fear of public speaking. It will help you to become an able speaker if you can prepare beforehand. For example, you can put in time on planning your presentation in detail and practicing it many times in secret. As you get more and more familiar with your material, you’ll be able to fine-tune (微调) the details of your presentation and this will make you a confident speaker. Your speech will become excellent in terms of style and content.
Remember that the more you get into this pattern of feeling good about yourself, the stronger you will feel about approaching events when you have to make a speech. You can also work on physical details such as adjusting your tone (音调) before the presentation by doing some warm-up exercises.
In a word, believing in yourself and presenting yourself well can help you deeply impress your audience. And after a few speeches you’ll notice yourself overcoming the sense of panic that you now feel in public speaking situations.

What do you usually use your cellphone for? Calling friends or sending them text messages?
As technology develops,nowadays cellphones can do much more than that.They have become all-in-one cell-phones.
A typical example is Apple’s phone.The touch-screen cellphone plays music,connects to the Web,sends emails and takes photos. More than 1 million Apple’s phones have been sold since it was sold in June.
“Today’s young people enjoy using all kinds of digital functions,such as those of a music player,a camera and even a computer. An all-in-one cellphone is easy to carry. That is the goal of developing a technology to make our lives more convenient,simple and relaxed,said Professor Ding Shouqian at Nankai University.
However, the all-in-one cellphones come with some problems. Users have complained that they are too complicated to use them, and that their battery life is too short. Cellphone producers say that they are working hard to make their phones even better.
It is very convenient to use it. “We are trying to make the cellphones in a way that people can quickly move from phoning to taking pictures to listening to music, said Alastair Curtis, Nokia’s chief designer.“If you look at the Nokia 3250 model, it has a twisting(转动) bottom. So you twist it half a turn,and it’s in camera mode. You twist it another 90 degrees, and it’s in music player mode.”Japanese companies such as Toshiba and Fujitsu are also working to develop a new kind of battery for cellphones.
If all the problems are solved in the future, all-in-one phones will change our lives for the better.

Until the twentieth century cigarettes were not an important threat to public health. Men used tobacco mainly in the form of cigars. Most women did not use tobacco at all.
The cigarette industry began in the 1870s with the development of the cigarette manufacturing machine. This made it possible to produce great numbers of cigarettes very quickly, and it reduced the price.
Today cigarette smoking is a widespread habit. About forty-three percent of the adult men and thirty-one percent of the adult women in the United States smoke cigarettes regularly. It is encouraging to note, however, that millions of people have given up the smoking habit. Seventy-five percent of the male population and forty-six percent of the female population have smoked cigarettes at some time during their lives, but twenty-six percent of these men and eleven percent of the women have stopped smoking. The number of persons who have given up smoking is increasing.
Men as a group smoke more than women. Among both men and women the age group with the highest proportion of smokers is the age group 24-44. Income, education and occupation all play a part in determining a person’s smoking habits. City people smoke more cigarette than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, ___________, he is likely to smoke more packs of cigarettes per day.
The situation is somewhat (有点) different for women. There are slightly more smokers among women with higher family incomes and higher education than among the lower income and lower educational groups. These more highly educated women tend to smoke more heavily.
Among teenagers the picture is similar. There are fewer teenager smokers from upper-income and well-educated families. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.

Most drinks stating that they are fruit-flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.
“Shoppers need to check the labels (标签)before buying drinks, though sometimes the actual content can be non-existent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. 1 It will increase profits, and consumers won’t always realize they are being tricked.”
Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry-flavored products sold in stores. 2 Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.
3 Let’s take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.
4 Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. 5 Unfortunately, it is also legal and widespread,” Tokelove said. “It’s time to take measures to protect the consumers’ rights.”
A.The products which contain real fruit are popular with people. |
B.Even products advertised as more natural often contained no fruit. |
C.They found that about 60 percent of them didn’t contain any fruit at all. |
D.If companies can cut their costs by using flavoring, they are likely to do so. |
E. It is important and necessary to demand a small amount of flavoring in the products.
F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.
G. The Food Commission suggested all flavors used in a product should be listed on the packaging.
Each summer, you hear news about a sports player being rushed to the hospital or passing out because the heat was just too much. If you follow some basic safety tips, you’ll be safe and happy playing outside for years to come.
Drinking water is crucial to your health in the heat. This is the first thing that everyone says when it is hot outside. You should not drink soda, coffee, or iced tea when you’re playing outside, and for a few hours after you get inside too.
Be sure to take enough breaks to let your body rest. If you feel that your coach don’t let you take enough breaks in the heat, don’t wait until you feel awful to march to the sidelines. Once you feel bad, it’s usually too late. Just be honest with your coach when you need breaks. He’ll understand.
When you do have a break, don’t sit in the sun. With the sun beating down on you, you’ll only heat up and sweat more. Try to grab a seat in the shade under a tree, or even better, go indoors for a little while. Cooling yourself down can help you stay active longer.
The signs of dehydration(脱水)can be tough to recognize. They include a dry or sticky mouth, dry skin, a headache, and dizziness(头晕). You might not always feel thirsty, so watch out for the signs of dehydration, and get yourself into the shade and get some water before it gets worse.
The earlier in the day you start your workout or practice, the cooler it will be. If you can start practice before the sun comes up, you have a few good hours to practice in the cool hours of the morning. Also, the earlier you practice, the earlier you can be done, which gives you some good recovery time when the heat gets bad in the afternoon. If you need more practice time, a good idea is to take a break when the heat is bad and come back to the field later in the evening, when the sun is setting.
As long as you pay attention to the above, playing sports safely in the heat isn’t a difficult thing.

The Most Direct Solution to Any Problem
When trying to solve various problems in life, an approach I find very useful is to first identify what I’d consider the most direct solution, regardless of how I feel about actually implementing (实施) it. What is the clearest, most direct path to my goal or the most efficient way to get around an obstacle?
Many problems will have multiple direct solutions, but often these solutions will be unpleasant at first glance because they’ll require courage, self-discipline, creativity, or persistence to implement.
For example, suppose you want to lose weight. And suppose we can say that one of direct solutions is to eat the same as you’re eating now and increase your exercise output by 500 calories a day. It may require discipline and persistence, but most people would agree that it will work if you follow through.
Another example: However, you don’t know how that person feels about you. One direct solution would be to simply walk up, explain your thoughts and feelings, and ask if she or he is interested in discussing the possibility of a closer relationship. This will take less than a minute to say, and whatever the outcome is, at least you know where you stand. Anyhow it’s very simple and straightforward.
What’s the simplest and quickest way to reach your goal, assuming that you had limitless courage and discipline?
A.Of course this solution may require a lot of courage toovercome the possibility of rejection. |
B.But if we can get ourselves to follow through, we know the solutions will actually work. |
C.See if you can identify the most direct solution to some of your problems. |
D.So the best way to overcome the difficulty is to ask your friends for advice. |
E. If you implement this rather simple solution, you’ll lose weight.
F. Suppose you’re interested in starting a relationship with someone.
G. However, the solution implemented does not work.

Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.
But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.
Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片,大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.
“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”

Directions: Read the following passage. Answer the questions according to the information given in the passage.
Kids and Ponds
Years ago there was a group of kids who would hang around at some local ponds in the woods near their houses in Warwick, Rhode Island. In summer they caught frogs and fish. When winter arrived they couldn't wait to go skating. Time passed, and the ponds became the only open space for the kids to enjoy themselves in that neighborhood.
One day. a thirteen-year-old boy from this group of kids read in the local newspaper that a developer wanted to fill in the ponds and build over a hundred small houses called condominiums. So the boy went door to door and gathered more than two hundred signatures (签名)to stop the development A group of citizens met and decided to support him.
At the meeting of the town planning board (委员会),the boy was quite nervous at first and spoke very softly. But when he saw the faces of his friends and neighbors in the crowd and thought about what was happening to their favorite ponds,his voice grew louder. He told the town officials that they should speak for the citizens. He also insisted that they should leave enough space for children. A few days later,the developer stopped his plan.
Nine years later, when that teen was a senior in college, he was informed that the developer was back with his proposal to build condominiums. Now twenty-two years old, he was studying wetlands ecology. He again appeared before the town planning board. This time as an expert witness, he used environmental protection laws to explain restrictions on development in and around wetlands and the knowledge of wetlands ecology to help improve the development. Finally some condominiums were built, but less than half the number the developer wanted. The ponds where those kids used to hang around were protected by a strip of natural land,and are still there today.

Teamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations (调查) are almost always carried out by teams of people working together. Ideas are shared, experiments are designed, data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone.
Several times throughout the year you may be asked to work with one or more of your classmates. Whatever the task your group is assigned, a few rules need to be followed to ensure a productive and successful experience.
What comes first is to keep an open mind, because everyone’s ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Choose a role on the team that is best suited to your particular strengths. Thirdly, always work together, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual (相互的)support and trust often makes a great difference.
Activities like investigations are most effective when done by small groups. Here are some more suggestions for effective team performance during these activities: Make sure each group member understands and agrees to the task given to him or her, and everyone knows exactly when , why and what to do; take turns doing various tasks during similar and repeated activities; be aware of where other group members are and what they are doing so as to ensure safety; be responsible for your own learning, though it is by no means unwise to compare your observations with those of other group members.
When there is research to be done, divide the topic into several areas, and this can explore the issue in a very detailed way. You are encouraged to keep records of the sources used by each person, which helps you trace back to the origin of the problems that may happen unexpectedly. A format for exchanging information (e.g., photocopies of notes , oral discussion, etc.) is also important, for a well-chosen method not only strengthens what you present but also makes yourself easily understood. When the time comes to make a decision and take a position on an issue, allow for the contributions of each member of the group. Most important of all, it is always wise to make decisions by compromise and agreement.
After you’ve completed a task with your team, make an evaluation of the team’s effectiveness — the strengths and weaknesses, opportunities and challenges.

Have you ever wondered why birds sing? 1 After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy.
2 Their singing is actually a warning to other birds to stay out of their territory. Do you know what a "territory" is? A territory is an area that an animal, usually the male, claims(声称) as its won. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. 3 If so, you have actually scared the stranger away without having to fight him. 4 But he expects an outsider almost all the time, especially at nesting(筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird' s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
5 Most of it has to do with attracting males and setting up territories.
A.A bird does the same thing. |
B.Maybe you thought that they were just happy. |
C.Shouting loudly is just like a bird's screaming. |
D.You can see that birds have a language all their own. |
E. Probably this would be enough to frighten him away.
F. However they sing most of the time for a very different reason.
G. So, just like human beings, birds sing for almost the same reasons.

The word science is heard so often in modern times that almost everybody has an idea of its meaning. However, its definition is difficult for many people. The meaning of the term is confusing, but everyone should understand its meaning and objectives (目标). Just to make the explanation as simple as possible, suppose science is defined as classified knowledge or facts.
Even in the true science, distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example, hypotheses(假设) and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited. The exact status of any explanation should be clearly labeled to avoid confusion.
The objectives of science are primarily the discovery and later the understanding of the unknown. Man cannot be satisfied with recognizing that secrets exist in nature of that questions are unanswerable; he must solve them. Toward that end, specialists in the field of biology and related fields of interest are directing much of their time and energy.
Actually, two basic approaches lead to the discovery of new information. One, aimed at satisfying curiosity, is referred to as pure science. Sometimes practical-minded people miss the point of pure science in thinking only of its immediate application for economic rewards. However, one should remember that the construction of the microscope had to come before the discovery of the cell. The host of scientists devoting their lives to pure science are not apologetic about ignoring the practical side of their discoveries; they know from experience that most knowledge is eventually applied.
The other is aimed at using knowledge for specific purposes--for instance, improving health, raising standards of living, or creating new consumer products. In this case, knowledge is put to economic use. Such an approach is referred to as applied science.
