Strange things happen to time when you travel, because the earth is divided into twenty-four time zones, one hour apart. You can have days with more or fewer than twenty-four hours, and weeks with more or fewer than seven days. If you make a five-day trip across the Atlantic Ocean, your ship enters a different time zone every day, As you enter each zone, the time changes one hour. Traveling west, you set clock back; traveling east, you set it ahead. Each day of your trip has either twenty-five or twenty-three hours. If you travel by ship across the Pacific, you cross the International Date Line. By agreement, this is the point where a new day begins. When you cross the line, you change your calendar one full day, backward or forward. Traveling east, today becomes yesterday; traveling west, it is tomorrow. 46.Strange things happen to time when you travel because _______ A.no day really has twenty-four hours B.the earth is divided into time zones C.time zones are not all the same size D.no one knows where time zones begin 47.The time difference between two neighboring zones is ________ A.one day B.twenty-five hours C.one hour D.twenty-three hours 48.According to paragraph 2, it seems true that the Atlantic Ocean______ A.is one time zone B.is divided into five time zones C.is divided into twenty-four time zones D.cannot be crossed in five days 49.If you cross the ocean going east, you set your clock______ A.ahead one hour in each new time zone B.ahead one hour for the whole trip C.back one hour in each new time zone D.back one hour for the whole trip 50.The International Date Line is the name for ______ A.the beginning of any new time zone B.any point where time changes by one
hour C.the point where a new day starts D.any time zone in the Pacific Ocean Task 2 Directions: This task (No.51 to 55) is the same as Task1 Today almost 70% of the electrical power we use comes from power plants that use fossil fuels (矿物燃料) to make electricity. Fossil fuels, such as oil, coal, and natural gas, are burned to make electricity. Burning fossil fuels releases pollution and carbon dioxide gas (CO2) into the air. The more fossil fuels we burn, the warmer the air around Earth gets. So building fossil fuel plans is not always the best answer. Actually, there are other ways to make electricity without burning fossil fuels. People have been using the power of wind for centuries. Wind power won’t solve all our energy problems, but it can help meet some of the demands in certain places. Since the late 1800s, scientists have been working to turn the sun’s energy into electricity by using solar cells (太阳能电池). The problem is, solar cells are very expensive. Another way to make electricity is to use nuclear energy. It has been used for more than 50 years. Today about 10 percent of all the electricity used in the U.S.A. comes from this source. Although nuclear power doesn’t pollute the air as the burning of fossil fuels does, there is a major drawback . The waste products from nuclear power plants are dangerous and must be stored in safe places. Many people are concerned about the safety of nuclear power. 51.The best title for this passage may be ________ A.The Importance of Electricity B.The Pollution of Making Electricity from Fossil Fuels C.The Advantage of Using Nuclear Energy D.Means of Making Electrical Power 52.Which energy has damage to us according to the passage? A.Wind power B.Fossil
fuels C.Solar power D.Water power 53.We can infer from the passage that _________ A.burning fossil fuels to make electricity is widely used B.wind power is a widespread way to make electricity C.energy problems will soon be solved D.nuclear energy will solve all the energy problems we are facing 54.What does the underlined word “drawback”(in Para.3)mean? A.effect B.advantage C.disadvantage D.concern 55.Which of the following statements is TRUE according to the passage? A.Fossil fuels should be encouraged to use to make electricity B.Not all the areas could use wind power. C.Solar energy costs the most D.Using nuclear energy will not produce negative effect. Task 3 Directions: This task (No.56 to No.60) is the same as Task 1. A new study by the Development of Health in Taiwan shows that more than half of the adult population in Taiwan lacks an understanding of health problems. More than 2,000 adults took part in the survey to find out about their knowledge of diet, health-care, disease control and medicine. Surprisingly, only 51% of the people surveyed understand that common cold has no cure, and taking medicine is absolutely no use at all. The problem is mad worse by doctors who give their patients large doses of useless drugs. More than two-thirds believe that it is only the nicotine in cigarettes rather than the other chemicals that causes cancer. These people believe that if they smoke “light” cigarettes with less nicotine, they will lead to more illness, suffering and early death. But the outlook for health education in Taiwan is not all negative. The survey concludes that younger Taiwanese have a better understanding of health concerns than their parents, while
senior citizens have the least understanding among the three age groups. 56.The purpose of the survey is to find out _______ A.why people neglect their health B.what people know about health C.when to provide health education D.who is more likely to become ill 57.Which of the following is TRUE about medicines for cold? A.They can cure common cold. B.Doctors often discourage the patients from taking them. C.About 51% of the patients take them. D.Some Taiwanese take them unnecessarily. 58.According to the survey, most Taiwanese believe that ____. A.only nicotine leads to cancer B.few people will get cancer C.”light ”cigarettes make people healthy D.other chemicals besides nicotine cause cancer 59.About ______ of Taiwanese adults smoke A.one-third B.two-thirds C.a half D.a quarter 60.The survey shows that ________ have the best understanding of health concerns. A.senior citizens B.middle –aged citizens C.younger Taiwanese D.Taiwanese smokers Task 4 Directions: The following is a business letter. After reading it , you should answer each of the 5 questions (No.61 to No.65)in no than 3 words. The answers should be written after the corresponding number on the Answer Sheet. Dear Mr. Robert, Although we sent you your goods on time, we have waited nearly two months for you to pay the balance of $5000, which is over due. When you ordered the shipment of computers, you requested that we send you the entire order no later than June 1, and we shipped the goods by air freight on May 25. As you agreed in our original credit arrangement (赊账协议), payment was due in 30 days, on June 30. Yet, as it is already August 26, we still have
