People called this the time of the Gold Rush.A gold miner came into a city looking for a pair of pants. He wanted pants strong enough to standup to the rough work of mining. He met a young man named Levi, who sold heavy cloth for tents and wagon tops. They asked a tailor to use heavy cloth for their pants. Then Levi went into the business of making work pants. He asked his brothers to send him some strong blue cotton cloth called denim (斜纹粗棉布). With this blue denim cloth, Levi started making the kind of pants we call blue jeans today. They were sewed up in the same way as other pants.In 1860, a miner said that the pockets weren't strong enough to hold the pieces of gold he found. The pockets kept falling off the pants. The cloth was all right. It was the thread that wasn't strong enough. So Levi used rivets (铆钉) to attach the pockets onto the pants.Cowboys needed tough pants, too. They liked their pants to fit tightly. But the rivets marked the cowboys' saddles. So Levi covered the rivets with cloth. Then everybody was happy.26.This article as a whole is about __________________.A. how people got blue jeansB. the Gold Rush in CaliforniaC. How blue jeans are madeD. The kind of pants cowboys' wear27.While not stated in the article, you can tell that __________________.A. everybody who went to California got a lot of goldB. Levi found riches in the gold fieldsC. Levi sold more jeans to cowboys than to gold minersD. Levi made more money than many gold miners28.The word this in the last sentence of the first paragraph refers to ___________.A. CaliforniaB. the discovery of goldC. many people looking for goldD. the nation at this time29.Levi used strong blue cotton cloth to make pants because __________.A. gold miners liked the blue colorB. this was the only cloth he hadC. miners wanted pants which could stand rough workD. cowboys liked their pants to fit tightly30.Which of the following sentences is NOT true?A. It was Levi who started the business of making blue jeans.B. It was one tailor who started making blue jeans.C. It was in California that blue jeans first became popular.D. It was in California that gold was discovered.Questions 31 to 35 are based on the same passage or dialog.Rote-learning (死记硬背), spoon-fed education, produces a brand of kids that don't know what to do when entering university. They are disciplined into following, not leading. Yet the future depends on creativity and imagination. The world needs creators, makers and shakers of the new centuries, not the followers of the past centuries. As the numbers increase at college and university level, more students from the lower ends are likely to be thrown into a process designed to choose only learners that have proved excellent in listening to teachers.There are three ways to learn: looking, listening and doing.Students and teachers today are a product of learning by listening. The computer may not be liked by traditional teachers, who use rote-learning to put information, which will be out of date in a few years, into the heads of the students. With computer learning you learn by looking, listening and doing; you use three methods of learning, not just one. Therefore, you can learn faster.The changing speed of information is frightening. What we learn now will be out of date in the near future. So what students are learning now at school may be replaced by the time they finish university. We have to learn by choice what to forget. Rote-learning for exams is one thing, but wouldn't it be better to learn how to learn? The students at university today could possibly be doing a job in the not too distant future which has not yet been invented.31.According to the author, the future doesn't need ____________.A. creativityB. imaginationC. creatorsD. followers32.In the author's view, how can students learn well?A. Carefully listen to the teacher in class.B. Take down every single word said by the teacher.C. Learn all the notes by heart.D. Combine listening with looking and doing.33.What does the author mean by "The changing speed of information is frightening"?A. We don't have enough time to adjust ourselves to the speed of information.B. What we learned today may not be useful tomorrow.C. The pace of life is too fast.D. The world is changing every minute.34.What does the last sentence of the passage tell us?A. Rote-learning is completely harmful.B. Students may have to do jobs which are not yet in existence.C. It's better to learn how to learn than learn what to forget.D. Students must imagine the future.35.The author's attitude towards rote-learning is _________.A. approvingB. disapprovingC. confidentD. opposite to what the words sayQuestions 36 to 40 are based on the same passage or dialog.If the population of the Earth goes on increasing at its present rate, there will eventually not be enough resources left to support life on the planet. One possible solution to the problem has recently been suggested by an American scientist, Professor Carl Sagan: he believes that before the Earth's resources are completely used up it will be possible to change the atmosphere (大气圈) of Venus (金星) and so create a new world almost as large as the Earth itself. The difficulty is that Venus is much hotter than the Earth and has only a tiny amount of water.Sagan suggests that algae (藻类), plant life that can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be produced in conditions similar to those on Venus. The algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the gasses in the atmosphere and change them into oxygen that people can breathe. But before man can set foot on Venus, it will be necessary for the oxygen to produce rain to cool the planet, so that after a few years conditions like those on Earth will be produced.If the experiments are successful, life will become possible there but it will not be pleasant at first. When they go to Venus, the first citizens will have to take plenty of water with them and get used to days and nights lasting 60 Earth days. But there will also be some advantages. They will live longer because their hearts will suffer less stress than on Earth.36.Men may eventually move to Venus because ______________________.A. there are many people on the EarthB. we have used too much oil and waterC. the limited resources can't support life on the EarthD. people take up too much space37.Now it is difficult for us to move to Venus because ______________________.A. it is too hot for men to land onB. there is no water thereC. we cannot change the environment thereD. it's a long distance for us to go there38.The algae play a very important role in the possible solution because_________________________.A. they can be produced easily on the EarthB. there are a lot of them on VenusC. they can be easily carried to VenusD. they can live in hot and cold conditions and produce oxygen39.The first citizens will find life on Venus not pleasant because ___________.A. their hearts will suffer more stressB. their days and nights will last quite longC. there are not any houses thereD. there is too much water there40.One of the advantages the first citizens on Venus will enjoy is ___________.A. they will have much more spaceB. they won't suffer from heart diseaseC. their life will last longerD.they will have better living conditions。
