She wanted to improve her English, because it could help her get a better job, maybe even a job teaching English someday. She’s interested in traveling and studying different cultures. She said that Brazilians try to copy North American customs, so she was interested in understanding why.Before coming to the U.S., Poliana had a certain image of North Americans. She got her image of North Americans from watching North American TV and movies in Brazil. She saw several Hollywood movies about high schools in the U.S., and she imagined high school could be a lot of fun. High school students seemed to have a lot of freedom. She imagined they participated in a lot of fun activities both inside and outside of school. However, she now thinks that Brazilian students have more fun and freedom in school.Poliana sometimes feels disappointed because outside of school there are few places for young people to meet their friends and talk. In Brazil, young people often get together at parties or at a shopping mall.In addition, Poliana thinks most North American students pretend to like her, because she comes from a foreign country, but actually don’t make an effort to get to know her well. She also feels North American students often discriminate against other students who don’t have fashionable clothes and hairstyles. In her opinion, North Americans aren’t open to different cultures and customs.65. Why did Poliana come to the U.S.?A. Because she was interested in traveling and studying different cultures.B.

As immigrants with little money, my parents were convinced that the time to teach children about investment building was as early as possible. They wanted my brother and me to get a head start on that long road to financial stability.Two years earlier my parents had helped me open my first bank account, and now my mother was introducing me to mutual funds. An enthusiastic pupil, I was soon contributing income from my paper route towards my investments.Then, later, as a high-school student with university on the horizon, I began to wonder how I could possibly afford the $2,200-a-year tuition. I had decided to major in sciences, with the aim of going on to medical school. In other words, there were a lot of years of tuition ahead of me.Clearly, it was time to step up my investing planning. I read investment magazines carefully and thoroughly for money-making advice. My comfort level grew, as did my investment. At the end of high school, I was able to pay for my university tuition. In fact, the proceeds of that investment supported me much of the way through medical school.Since Mom’s first chat nearly two decades ago, I have come a long way as an investor. Above all, I have seen firsthand how smart investing can help you reach important goals in life. It’s partly thanks to the good financial habits I picked up as a child that I’m enjoying a medical residency in Edmonton today — thanks, in other words, to my money-wise Mom and Dad.72.

Why did the writer’s mother encourage the writer to learn to invest?A. Because the writer liked to know something about financial facts of life.B. Because the writer was an enthusiastic pupil.C. Because the writer’s parents were immigrants with little money.D. Because the writer’s parents thought the children should know how to consume.75. What’s the main idea of the passage?A. Debt of gratitudeB. The memory of parentsC. Thanks to the proceeds of that investmentD. Success comes from financial stability(D)Scientists estimate that more than 60 percent of cancer deaths in the United States are preventable through lifestyle changes. Although there is no certain way to avoid all cancers, reducing individual risk factors significantly decreases the likelihood of getting many forms of this dangerous disease.The American Chemical Society estimates that smoking causes nearly 30 percent of all cancer deaths in the United States — that is, about 166,000 cancer deaths each year. All cancer deaths caused by tobacco smoking could be prevented completely by not smoking and not using smokeless tobacco. For those who already smoke, quitting will reduce the risk of developing cancer. Studies show that after about ten years of not smoking, a past smoker’s risk lowers to about the level of those who have never smoked.After quitting smoking, eating a healthy diet is the best way to lower the risk of cancer. Certain foods have been found to protect against cancer. Among these foods are cabbage, tomatoes, soy products, and foods high in vitamins A, C, and E. In addition, green and possibly black teas contain compounds that protect the body from cancer-causing substance.To lower cancer risk, diets should include little or no red meat. Other foods to avoid or consume in moderation include sugar, fat from animal products, and salt. Added fats and oils should come from vegetables, such as olives or corn, rather than from animal sources. Carbohydrates (碳水化合物) should come from whole grains, such as brown rice and whole wheat bread, rather than from processed foods, such as white rice and white bread.The risk of cancer of the esophagus (食道) increases with heavy alcohol consumption, and many studies suggest that consuming alcoholic drinks increases the risk of breast cancer as well. Studies show that limiting intake to two drinks a day for men, and one drink per day for women, reduces cancer risk.Low levels of physical activity have been implicated (牵连) in some cancer. Moderate activity for 30 minutes a day enhances the immune system, shortens the time food takes to move through the intestines (肠), and changes body composition and hormone levels. Researchers are studying how these effects might lower cancer risk.76. Which do you think is the best title for this passage?A. Lifestyle and DiseaseB. Tips for Cancer PreventionC. Causes of CancersD. How do We Remain Healthy?77. Which of the following is true according to the author?A. Those who have quitted smoking for 10 years and non-smokers have the same cancer risk .B. Once a smoker has stopped smoking, there is almost no chance of getting cancers.C. A balanced diet is absolutely effective in preventing one from getting cancer.D. A person drinking tea regularly will not be likely to suffer from cancer.78. What kind of people increase their chances of getting cancers?A. Their food contains less sugar, animal fat, and salt.B. One who is not moderate in drinking and eating.C. Those who have one or two drinks regularly and enjoy doing so with their families.D. Those whose diet contains a lot of red meat and not a little fruit.79. The last paragraph implies that ______.A. Food's staying in one's body for too long a time might be related to a kind of cancerB. Exercise can consume more whole grainsC. 30 minutes' physical activity is good for ordinary peopleD. Plenty of physical exercise is most important for one to remain healthySection CDirections:Read the following text and choose the most suitable heading from A-F for eachparagraph. There is one extra heading which you do not need.80.The earth is getting warmer. People burn coal, oil and gas and this produces carbon dioxide, methane and nitrous oxide. These gases, called ―greenhouse gases ‖, prevent the heat of the sun from leaving the earth ’s upper atmosphere and this makes the earth warmer.81.A few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. According to what they found, the scientists say that during the next 50 years about 25% of land animals and plants will become extinct. More than a million plant and animal species will be extinct by 2050.82. More than 10% of all plants and animals will become extinct. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we could save many more plants and animals from extinction.83.The scientists studied some regions of the world with a very rich biology. These regions were Europe, Australia, Central and South America, and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill, to get cooler. In flat areas, such as deserts, plants and animals would have to move a very long distance to get cooler, so they are in greater danger of extinction.84.The scientists found that half of the 24 species of butterflies they studied in Australia would soon become extinct. 60% of the species in the Kruger National Park in South Africa would also die out, and more than 100% of the 300 South Africa plant species they studied would also become extinct. One of the plants in danger of extinction is the national flower of South Africa, the King Protea. They studied 163 tree species in the Cerrado region of Brazil and found that 70 would become extinct. Many of the plants and trees that live in this region live nowhere else in the world. In Mexico, they studied 1,870 species and found that more than 30% of these were in danger of extinction.第II卷(共45分)I.TranslationDirections: Translate the following sentences into English, using the words given in the brackets.1. 给他这么多钱毫无意义。
