1. _____: less red meat and more fibre, less saturated fat (饱和脂肪) and more fruit and veg, right? Wrong, according to a controversial new book by nutritionist Zoe Harcombe. In the book, Harcombe charts her careful journey of research into studies that underpin (巩固) dietary advice-and her myth (误 区)-breaking conclusions are surprising. Myth: 2._____. "Real fat is not bad for us," says Harcombe. It" s man-made fats we should be demonising. Why do we have this idea that meat is full of saturated fat? In a 100g pork chop, there is 2.3g of unsaturated fat and l.5 g of saturated fat. Myth: We should eat more fibre. For three decades, we have eaten fibre into our bodies to help us feel full and keep our digestive systems moving. 3._____, says Harcombe. The advice to eat more fibre is put forward along with the theory that we need to clean our digestive systems. But essential minerals are absorbed from food while it is in the intestines (肠道), so why do we want to wash everything out? Concentrate on not putting bad food in. Myth: You need to eat five portions of fruit and veg a day. "Five-a-day is the most well-known piece of nutritional advice," says Harcombe. "You" d think it was based on firm evidence of health benefit. 4._____." Five-a-day started as a marketing campaign by 25 fruit and veg companies and the American National Cancer Institute in 1991. There was no evidence for any cancer benefit. Myth: Fruit and veg are the most nutritious things to eat. Apparently not. Harcombe allows that vegetables are a great addition to the diet-if served in butter to deliver the fat-soluble (dissolved) vitamins they contain-but natural sugar, the fruit sugar in fruit, goes straight to the liver and is stored as fat. 5._____, says Harcombe, who adds:"Vitamins and minerals in animal foods-meat, fish, eggs and dairy products-beat those in fruit." |
A. Want to lose weight? Don"t trust these B. We think we know what to eat C. This is not a good idea D. Fat is bad for us E. Think again F. We need take more exercise G. Fruit is best avoided by those trying to lose weight |

Most of the 20th century has been a development on the Industrial Revolution taken to an extreme: people now own more products than ever before; there are enough nuclear weapons to destroy the earth several times over; there is hardly any forest left and pollution has got to the point where we buy water. Within a few years I predict you will be able to buy air. (There once was a time when you didn"t need to buy food or shelter either.) Important developments in the last century are the breaking down of the class structures left over from the Industrial Revolution stage, bringing with it the empowerment of the "common man": the working day is set by law to only 8 hours a day, everyone has the vote, the media has less obvious government control, people have landed on the moon, sent spacecrafts to Mars and so on. Families have also shrunk drastically (强烈地); the nuclear family came about, and especially in the last half of the 20th century, one-parent families are becoming more common. This shrinking in the size of the family shows the increased independence of people-once upon a time people had to live in large groups to survive. As humans have "become the gods", they have realized their individuality and independence and taken their control of the world to an extreme. In many countries the land is almost completely used in the production of food and as living space and they live in small cities which are entirely human constructed, made from materials which are also entirely human constructed (concrete, bricks) with hardly any remains of nature. Weeds are poisoned because they are messy; even parks have trees grown in tidy lines; grass is mowed to keep it short and so on. I think the massive drug "problem" troubling people is a result of too much of this influence, humans needing to escape the stark world they have created by entering fantasy worlds. Over the last 100 years, the 20th century consciousness has spread throughout the world; most of Asia has been thoroughly "Westernized", and most of the Third World is being overrun by Western ways of doing things and living. |
1. What" s the author most concerned about? |
A. The influence of pollution. B. Strong effects of development. C. Changed positions of humans as gods. D. The process of the Industrial Revolution. |
2. What is the author"s attitude towards the changes of the 20th century? |
A. Objective. B. Tolerant. C. Vague. D. Negative. |
3. What does the underlined word "stark" in Paragraph 3 mean? |
A. Unfair. B. Illegal. C. Dull. D. Violent. |
4. What can be inferred from the passage? |
A. Men"s individuality is over controlled. B. People have damaged nature too much. C. Men"s independence is partially limited. D. People show concern for nuclear families. |

(I) Recently, a solar powered plane took to the sky for the first time. It had passed an important test on the way to travel around the world. The plane took off from an airport in Switzerland at 45 km an hour It slowly rose above the fields and into the sky. During the 90-minute flight, the plane did several turns. It climbed nearly l.6 km above the countryside. Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012. The plane flies at 70 km an hour. That is faster than a bike and slower than a car. The pilots will keep the plane in the air for up to five days at a time. (II) Cities and states with more sidewalks and bike paths tend to have slimmer residents than locations where people must rely on vehicle transportation, according to a new study. The study shows active travel has significant health benefits, people who live in areas that are more conductive (有益的) to walking and cycling are more likely "to engage in these forms of active transport. Researchers analyzed data from all 50 US states and 47 largest US cities, along with international data from 14 countries. Results showed that walking and cycling rates could explain more than half of the differences in obesity rates among countries. The US doesn"t measure up well in the study, coming in at No. 12 out of 14 0n percent-age of trips adults take by bike or on foot. Australia came in last. The researchers suggest that in addition to infrastructure (基础设施) improvements, cities and states should create restrictions on car use, such as car-free zones, reductions in motor vehicle speeds, and limit more expensive car parking. |
1. What information can we get from the first passage? |
A. The first flight of the plane last 90 minutes. B. The second plane will be bigger and fly faster. C. The plane will fly for at most five hours at a time. D. The plane uses no fuel and goes faster than a car. |
2. The main purpose of the second passage is to _____. |
A. promote a new way of car traveling B. teach us how to keep residents slimmer C. tell us people in "active cities" are slimmer D. compare the living level of developed countries |
3. It can be inferred from the second passage that _____. |
A. Americans would take trips by car rather than by bike or on foot B. all the US states and largest cities are involved with this survey C. more expensive car parking can contribute to improve infrastructure D. the number of bikes in Australia may be the greatest of the 14 countries |
4. Which column of a newspaper may the two passages come from? |
A. Food and Safety. B. Science and health. C. Culture and Communication. D. Sports and Entertainment. |

Three key facts about rising sea levels need to be pointed out to the world"s politicians and planners: sea-level rise is now unavoidable (不可避免的), it will happen faster than most of us thought, and it will go on for a very long time. Even if greenhouse gas emissions (排放) stopped tomorrow, the oceans would continue to become larger as they get warm. The climate scientists estimate that sea-level rise may be in the range of 1 to 2 meters by 2100, with a small risk of an even greater rise. For many islands and low-lying regions, even small rises will cause disasters. But for most countries, the problem is what has been built on that land: New York, Sydney and Tokyo, to mention just a few cities. Unless something can be done, great areas of urban network will disappear under the waves. It will take a great engineering effort to protect these cities-an effort that may be beyond economies that have been brought to their knees. None of this means we should fear, and stop trying to forbid emissions. But together with these efforts, we need to start acting now and we must stop building in danger zones. Billions of dollars are being spent on constructing homes, offices and roads in vulnerable (脆弱的) coastal areas. For instance, the skyscrapers of Shanghai are being built on land that is mere 4 meters above sea level on average, and they are sinking under the weight of the buildings. Therefore, planning for new coastal developments is to go against reality. If we want to build a lasting heritage for our children, we should do so on the plentiful land that is in no danger from the sea. It is one of the effective ways to slow down climate change, and we should be acting on it now. |
1. The most possible reason for the rising of sea levels should be _____. |
A. greenhouse gas emission B. temperature change of the oceans C. vulnerable coastal area D. fast urban development and expansion |
2. New York, Sydney, and Tokyo are mentioned in this passage to show _____. |
A. climate change has been completely out of control B. modem cities are usually built along the coastline C. the coastline is very important for modem countries D. climate change can do harm to economies |
3. The effort to protect coastal cities may be beyond economies because _____. |
A. much money has been wasted to build coastal cities B. people have lost confidence in their economies C. economy development has made climate change worse D. protecting the cities may cost more than what has been obtained |
4. According to the author, we should _____ to deal with sea-level rise. |
A. move big cities like New York and Shanghai to higher places B. stop building skyscrapers in big cities like Sydney and Tokyo C. build cities on the land free from the danger of sea-level rise D. be aware of the danger of greenhouse gas emissions into the ocean |

Life insurance isn"t fun to buy. It forces you to think about your death: a subject many prefer not to confront. But there"s a single, over-riding reason to buy life insurance: to provide an income for your dependents should you die. Don"t depend solely on an agent to figure your life insurance needs. Rule-of- thumb estimates such as five or eight times your income are guesses; they may produce too little or too much insurance. Carry too little insurance and you may not provide a reasonable standard of living for your family after your death; carry too much and you may not enjoy a reasonable standard of living while you"re alive. Most people who have life insurance don"t have enough. The median (中值) amount of coverage for all adults with life insurance was only 15,000 pounds in 1984. That"s obviously not enough to sustain a family with young children for very long. Nationwide Insurance found that the married men in its 1984 survey carried an average of about 101,880 pounds in life insurance; they needed about 100,705 pounds more. Married women carried about 43,516 worth insurance but needed some 98,507 pounds more. How do you determine the amount of life insurance you would need to maintain your family"s current life-style if the bread-winner died? First, figure, what your family"s expenses would be if you died tomorrow. Then, analyze your assets (财产) and the sources of income that you can use to cover the expenses. Finally, subtract the assets from the needs. The result is the amount of additional insurance that you"ll need to buy. |
1. The passage intends to tell you ____. |
A. life insurance isn"t fun to buy B. life insurance is most important in maintaining your family"s current life-style C. life insurance is the result of amount of additional insurance you"ll need to buy D. how to determine the amount of life insurance you would need |
2. Life insurance is not fun to buy because ____. |
A. many people prefer not to confront the subject B. there is a single, over-riding reason C. it reminds you that you may die one day D. it forces you to think about your additional expenses |
3. Which of the following statements is NOT true? |
A. Estimates such as five or eight times your income are not reliable. B. These agents may produce too little or too much insurance. C. You must not rely on agents only to tell you how much life insurance you need. D. You should believe in either your agent or those empirical (经验的) estimates. |
4. If you carry too little or too much insurance ____. |
A. either you or your family might suffer B. you may not provide a reasonable standard of living for your family after your death C. you may not enjoy a reasonable standard of living while you"re alive D. you will know in the end that they are just wild guesses |
5. All of the following should be taken into account in determining the amount of your life insurance EXCEPT ____. |
A. analyzing your assets and sources of income B. adding up the ages of your dependents C. estimating your family"s expenses D. taking away the assets from the expenses |
