How far would you be willing to go to satisfy your need to know？Far enough to find out your possibility of dying from a terrible disease？These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的) tests，for everything from baldness to breast cancer，and the list is growing.Question is，do you really want to know what might eventually kill you？For instance，Nobel Prizewinning scientist James Watson，one of the first people to map their entire genetic makeup，is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年痴呆症)．
“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your life as you wait for that disease to hit you.It could really mess you up.” said Dr.Robert Green，a Harvard geneticist.
“Every ache and pain，” Smith suggested，could be understood as “the beginning of the end.”“That’s right.If you ever worried you were at risk for Alzheimer’s disease，then every time you can’t find your car in the parking lot，you think the disease has started.”
Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would，for lack of a better medical term，freak_out.But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives.In fact，most people think they can handle it.People who ask for the information usually can handle the information，good or bad，said Green.The first paragraph is meant to________.
| A．ask some questions |
| B．introduce the topic |

Moral（道德的）science is taught as a subject in most schools but with little effect. Perhaps part of the problem lies in the fact that morality is not a science, strictly speaking. It is too much of a social phenomenon, and also has too much of the personal and subjective things mixed within. Besides, morality itself changes with generations. So it is impossible to be defined in a textbook.
I remember sitting through forty minutes of moral lessons, which told stories about little children who never told lies and were rewarded for their goodness. It had little effect and left no impression on me, though.
If moral science has to be taught as a subject in schools, it needs a participatory(参与其中的) approach. When you tell a child about morals, you also have to deal with social norms（规范）and cultural differences. You have to explain that morality can be subjective, and be able to co-exist in society. You will probably have to refer to the morals of the present time.
The best way to tell a child how to live is to show him what is valued. If a child likes his friend, you have to make the child think about why. Once the child notices and recognizes goodness in others, he or she is likely to develop it as well.
In fact, children learn most of their morals by watching people around them. They absorb behavior patterns from teachers and older students. They watch to see what is rewarded and who is punished. They learn on the sports field and through social work. Moral science lessons should simply consist of letting them live and interact, and watch you support correct values and reward good behavior. Which is NOT the reason that moral science is taught in schools but with little effect?
| A．Morality doesn’t strictly belong to a science. |
| B．Morality is more like a social phenomenon. |
| C．Different generations have different moral ideas. |
| D．Morality can’t be written down in textbooks. |
The author describes his own experience of having moral lessons in order to _____.
| A．explain telling lies is not moral for little children. |
| B．advise people should be rewarded for their goodness. |
| C．show he has no opinions about moral science. |
| D．prove moral lessons in schools have little effect. |
When you tell a child about morals, you should________.
| A．tell him about social norms and cultural differences. |
| B．teach him to share personal moral ideas with others. |
| C．explain that nobody can influence his moral ideas. |
| D．say that the present morals are likely to be changed. |
What is the last paragraph mainly about?
| A．The value of teachers’ setting a good example. |
| B．The best way of teaching children about morals. |
| C．The influence of people’s behavior on morals. |
| D．The importance of rewarding good behavior. |
It’s great fun to explore new places—it feels like an adventure，even when you know you’re not the first to have been there. But make sure not to get lost or waste time going round in circles.
● Do the map reading if you’re being driven somewhere. It’ll be easier if you keep turning the map so it follows the direction you’re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn or you’ll have to move to the back seat.
● Get a group of friends together and go exploring. You'll need a good map, a compass , a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies . Tell someone where you’re going before you set out and let them know what time you expect to be back. The test is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.
● See if your school or a club organizes orienteering activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C, etc.)in the fastest time, or simply as a spare-time activity. Either way, its not only good fun, but a great way to keep fit. Sitting beside the driver, you should___________.
| A．look ahead to see where there’s a turn |
| B．direct the driver when necessary |
| C．move to the back seat if feeling uncomfortable |
| D．keep looking at the map to find a place to go to |
Why do you need to tell someone your exploration plan before setting out?
| A．To be saved in case of an accident. |
| B．To get information when in danger. |
| C．To share the fun with him/her in exploration. |
| D．To tell him/her what’s going on with the group members. |
Orienteering activities can______________.
| A．make people work fast |
| B．help people organize other activities |
| C．help people stay healthy |
| D．make people get prepared for sports |
The text mainly talks about____________.
| A．the fun of exploration |
| B．what to bring for exploration |
| C．the way to use a map in exploration |
| D．how to prevent getting lost in exploration |
What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster?
Yes, there really is a job where you can get paid to taste ice-cream. Just ask John Harrison, an＂Official Taste Tester＂for the past 21 years. Testing helps manufacturers to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream－as well as for developing over 75 flavors (味道).
Some people think that it would be easy to do this job: after all, you just have to like ice cream, right? No－there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this＂cool＂field.
In a typical morning on the job, Harrison tastes and assesses 60 ice-cream samples. He lets the ice cream warm up to about 12℉. Harrison explains,＂You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup.＂
While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance.＂Testing begins with the eyes,＂he explains. He checks to see if the ice cream is attractive and asks himself,＂Does the product have the color expected from that flavor?＂Next it’s time to taste!
Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy－－working at one cool job. What is John Harrison’s job?
| A．An ice-cream taster. | B．An official. |
| C．A chemist. | D．An ice-cream manufacturer. |
According to John Harrison, to be qualified in the＂cool field＂, it is helpful to ______.
| A．keep a diary of work |
| B．find out new flavors each day |
| C．have new ideas every day |
| D．have a degree in related subjects |
What does Harrison do first when testing ice cream?
| A．He stirs the ice cream. |
| B．He lets the ice cream warm up. |
| C．He tastes the flavor of the ice cream. |
| D．He examines the color of the ice cream. |
Which of the following is probably the best title of the passage?
| A．Tasting with Eyes | B．Flavors of Ice Cream |
| C．One Cool Job | D．John Harrison’s |
A man and his girlfriend were married. It was a large celebration. All of their friends and family came to see the lovely ceremony. Everyone could tell that the love they had for each other was true.
A few months later, the wife came to the husband with a piece of advice, “I read in a magazine, a while ago, about how we can strengthen our marriage,” she offered. “Each of us will write a list of the things that we find a bit annoying with the other person. Then, we can talk about how we can fix them together and make our lives happier together.”
The husband agreed. So each of them tried to think of the things that annoyed them about the other and wrote down what they came up with. The next morning, at the breakfast table, they decided that they would go over their lists.
“I’ll start,” offered the wife. She took out her list. It had many items on it, enough to fill three pages. In fact, as she started reading the list of the little annoyances, she noticed that tears were starting to appear in her husband’s eyes because he never thought that he had so many shortcomings.
The wife continued to read until she had read all three pages to her husband. “Now, you read your list and then we’ll talk about the things on both of our lists,” she said happily. Quietly the husband stated, “I don’t have anything on my list. I think that you are perfect. I don’t want you to change anything for me. You are lovely and wonderful and I wouldn’t want to try and change anything about you.” The wife, touched by his honesty and the depth of his love for her and his acceptance of her, turned her head and wept.
In life, there are enough times when we are disappointed, depressed and annoyed. We don’t really have to go looking for them. We have a wonderful world that is full of beauty, light and promise. Why waste time in this world looking for the bad, disappointing or annoying when we can look around us and see the wonderful things before us?Why were there tears in the husband’s eyes when the wife read his annoyances?
| A．Because he had no courage to face his shortcomings. |
| B．Because he was sorry that he didn’t find any annoyance about his wife. |
| C．Because he never thought he had so many annoyances in his wife’s eyes. |
| D．Because he didn’t think he deserved to have such a perfect wife. |
After hearing the husband’s words, the wife felt _________.
| A．sad and disappointed | B．moved and ashamed |
| C．satisfied and proud | D．surprised and confused |
The story is intended to tell us that ___________.
| A．disappointment cannot be avoided in our life |
| B．young couples should be more tolerant (宽容的) to each other |
| C．we should turn a blind eye to other people’s blame |
| D．we should try to look for and see the wonderful things around us |
Not long ago, people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life. Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings.
One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant (怀孕的)woman. Then, they played a recording of a short story. On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby.
The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story again and again.
Another study shows how mothers can strongly influence social development and language skills in their children. Researchers studied the children from the age of one month to three years. The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children’s activities and did not interfere ( 干预）unnecessarily. They tested the children for thinking and language development when they were three years old. Also, the researchers observed the women for signs of depression.The children of depressed women did not do as well in tests as the children of women who did not suffer
from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear.
These children also were less cooperative and had more problems dealing with other people. The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children. Children did better when their mothers were caring, even when they suffered from depression. According to the passage, which of the following is NOT the factor that influences intelligence development in babies?
| A．The environment. |
| B．Mother's sensitivity. |
| C．Their peers (同龄人) |
| D．Education before birth. |
What is the purpose of the experiment in which newborn babies heard the stories?
| A．To prove that babies can learn before they are born. |
| B．To prove that babies can learn on the first day they are born. |
| C．To show mothers can strongly influence intelligence development in their babies. |
| D．To indicate early education has a deep effect on the babies' language skills. |
Which group of children did the worst in tests of language skills?
| A．The children of depressed mothers who cared little for their children. |
| B．The children of women who did not suffer from depression. |
| C．The children of depressed but caring mothers. |
| D．Children with high communication abilities. |
What is the main idea of the passage?
| A．Scientific findings about how babies develop before birth. |
| B．Scientific findings about how time has an effect on babies' intelligence. |
| C．A study shows babies are not able to learn things until they are rice or six months old. |
| D．Scientific findings about how intelligence develops in babies. |
