Beginning in October, more than 13,000 McDonald’s (麦当劳)restaurants in America will use a new variety of cooking oil. McDonald’ s aims to make its French fries (油炸食品) and other fried foods healthier.
The change will not affect the taste or the number of calories in the food. But by changing the cooking oil, McDonald’s says, it hopes to cut by nearly half the amount of trans fatty acids (转换脂肪酸) in French fries and reduce the amount of saturated fats(饱和脂肪) by 16 percent. Scientists believe that trans fatty acids and saturated fats raise cholesterol(胆固醇) levels and increase the risk of heart disease.
McDonald’s new step is important because McDonald’s is an industry leader and other fast-food chains and food processors may follow the lead.
For McDonald’s ,the action comes at a time when Americans are becoming more and more concerned about; obesity (肥胖) and are increasing pressure on food companies to offer healthy and nutritious (有营养的) food to consumers.
After three years of study, McDonald’s officials say they are switching oil that is lower in saturated fats and trans fatty acids. McDonald’s says the change will not cause higher price for consumers.
Though there is some change, scientists say that the amount of trans fat in foods at McDonald’s and at other fast-food companies is still important.More than 13,000 McDonald’s restaurants in America will use a new kind of cooking oil to ______________.
| A．lower the costs of the products |
| B．maker its food taste hatter than ever before |
| C．cure (治愈) the heart disease |
| D．do good to the health of consumers |
The underlined ward "switching" here has the same meaning as " _______ ".
| A．turning on | B．turning off | C．changing | D．studying |
The main idea of the passage is __________ .
| A．McDonald’s is a pioneer in food products |
| B．McDonald’s is enlarging its restaurants in the world |
| C．fried foods can’t keep up with the development of modem society |
| D．McDonald’s is to use new cooking oil |
When a new kind of cooking oil is used in McDonald’s, ________
| A．the prices of McDonald’s foods will be a tot higher |
| B．consumers will find the taste of McDonald’s foods different |
| C．many other food companies will do what McDonald’s does |
| D．obesity will disappear in American society sooner or later |
Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.
In rejecting exercise, some people may be discouraged too much by caloric-expenditure（热量消耗）charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜饼). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports.
Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight. What is said about the average American in the passage?
| A．They tend to hate "light" beer and low-calorie bread. |
| B．They usually ignore the effect of exercise on losing weight. |
| C．Most of them were combining exercise with their diet. |
| D．They know the actors that play a positive role in keeping down body weight. |
"Even exercise professionals accept half a point here" means "They ".
| A．agree that the calories in a small piece of pastry can be easy to work off by exercise |
| B．partially believe diet plays a supporting role in weight reduction |
| C．are not fully convinced that dieting can help maintain one's new weight |
| D．are not sufficiently informed of the positive role of exercise in losing weight |
What was confirmed by the Boston University Medical Center's study?
| A．Controlling one's calorie intake is more important than doing exercise. |
| B．Even occasional exercise can help reduce weight. |
| C．Weight reduction is impossible without exercise. |
| D．One could lose ten pounds in a year's time if there's no increase in food intake. |
What is the author's purpose in writing this article?
| A．To stress the importance of maintaining proper weight. |
| B．To support the statement made by York Onnen. |
| C．To show the most effective way to lose weight. |
| D．To introduce the study of the Boston University Medical Center. |
Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn’t become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around. But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid-1700s, a Frenchman came up with a new design of road — a base layer (层) of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs (the central part of a wheel) came into being, followed by the pneumatic type (充气轮胎） in 1846.Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads (柏油路). As wheel design took off, vehicles got faster and faster.What might explain why transport wheels didn’t become popular for some time?
| A．Few knew how to use transport wheels. |
| B．Humans carried farming tools just as well. |
| C．Animals were a good means of transport. |
| D．The existence of transport wheels was not known. |
What do we know about road design from the passage?
| A．It was easier than wheel design. |
| B．It improved after big changes in vehicle design. |
| C．It was promoted by fast-moving vehicles. |
| D．It provided conditions for wheel design to develop. |
How is the last paragraph mainly developed?
| A．By giving examples. | B．By making comparisons. |
| C．By following time order. | D．By making classifications. |
What is the passage mainly about?
| A．The beginning of road design. |
| B．The development of transport wheels. |
| C．The history of public transport |
| D．The invention of fast-moving vehicles. |
Mothers and daughters go through so much — yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother, Sheila Solomon Klass, both gifted professional writers, prove to be ideal co-writers as they examine their decades of motherhood, daughterhood, and the wonderful ways their lives have overlapped (重叠).
Perri notes with amazement how closely her own life has mirrored her mother’s: both have full-time careers; both have published books, articles, and stories; each has three children; they both love to read. They also love to travel — in fact, they often take trips together. But in truth, the harder they look at their lives, the more they acknowledge their big differences in circumstance and basic nature.
A child of the Depression (大萧条), Sheila was raised in Brooklyn by parents who considered education a luxury for girls. Starting with her college education, she has fought for everything she’s ever accomplished. Perri, on the other hand, grew up privileged in the New Jersey suburbs of the 1960s and 1970s. For Sheila, wasting time or money is a crime, and luxury is unthinkable while Perri enjoys the occasional small luxury, but has not been successful in trying to persuade her mother into enjoying even the tiniest thing she likes.
Each writing in her own unmistakable voice, Perri and Sheila take turns exploring the joys and pains, the love and bitterness, the minor troubles and lasting respect that have always bonded them together. Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork. Perri admits that she can’t sort out all the mess in the households, even though she knows it drives her mother crazy. Together they compare thoughts on bringing up children and working, admit long-hidden sorrows, and enjoy precious memories.
Looking deep into the lives they have lived separately and together, Perri and Sheila tell their mother-daughter story with honesty, humor, enthusiasm, and admiration for each other. A written account in two voices, Every Mother Is a Daughter is a duet (二重奏) that produces a deep, strong sound with the experiences that all mothers and daughters will recognize.Why does Perri think that her own life has mirrored her mother’s?
| A．They both have gone through difficult times. |
| B．They have strong emotional ties with each other. |
| C．They have the same joys and pains, and love and bitterness. |
| D．They both have experiences as daughter, mother and writer. |
The word “luxury” in Paragraph 3 means ______.
| A．something rare but not pleasant |
| B．something that cannot be imagined |
| C．something expensive but not necessary |
| D．something that can only be enjoyed by boys |
What is Paragraph 4 mainly about?
| A．The content of the book. | B．The purpose of the book. |
| C．The influence of the book. | D．The writing style of the book. |
How are women’s lives explored in this book?
| A．In a musical form. | B．Through field research. |
| C．With unique writing skills. | D．From different points of view. |
I am Sergey Brin! I was born in Moscow. In 1979, when I was 5, my family immigrated to the United States. I remember that on my 9th birthday I got my first computer “Commodore 64”.
Later I graduated with honors in the University of Maryland in Mathematics and IT. The main field of my science research was the technologies used to collect data from unsystematic sources as well as large quantities of texts and science data. I was the author of dozens of articles in leading American academic magazines.
The greatest event in my life happened when in 1998 I was preparing for the defense（论文答辩）of my Doctor’s degree in Stanford University. There the fate made me meet Larry Page—a young computer genius. Larry belonged to the intellectual society. Larry and I quickly became friends when we worked together.
We were searching day and night on the Internet. We were finding a lot of information but with the feeling we still couldn’t find enough of what we were looking for. Naturally the idea for a search engine that would allow specific information to be found in the endless pool of data was born like it came to us. It wasn’t our plans but we gave up the education at the university. You know the next part, maybe we managed to turn an ordinary garage in Meplo Park, California, the U. S. A. into our first office, in which Google was born. With excitement we typed the name of the thing which we created with love on September 14th 1998—www. google.com.

In 1939 two brothers, Mac and Dick McDonald, started a drive-in restaurant in San Bernardino, California. They carefully chose a busy corner for their location. They had run their own businesses for years, first a theater, then a barbecue（烤肉）restaurant, then another drive-in. But in their new operation, they offered a new, shortened menu: French fries, hamburgers, and sodas. To this small selection they added one new idea: quick service，no waiters or waitresses, and no tips.
Their hamburgers were sold for fifteen cents. Cheese was another four cents. Their French fries and hamburgers had a remarkable uniformity（一致性）, for the brothers had developed a strict routine（程序）for the preparation of their food, and they insisted on their cooks’ sticking to their routine. Their new drive-in became surprisingly popular, particularly for lunch. People drove up by the hundred during the busy noontime. The self-service restaurant was so popular that the brothers had allowed ten copies of their restaurant to be opened. They were content with this modest success until they met Ray Kroc.
Kroc was a salesman who met the McDonald brothers in 1954 when he was selling milkshake-mixing machines. He quickly saw the special attraction of the brothers’ fast-food restaurants and bought the right to franchise（特许经营）other copies of their restaurants. The agreement included the right to duplicate（复制） the menu, the equipment, even their red and white buildings the golden arches（拱门）.
