droughts(干旱)and floods.Unfortunately,in many parts of the world,man has not realized that the third of these services is the most important.In his eagerness to draw quick profit from the trees,he has cut them down in large numbers.Two thousand years ago a rich and powerful country cut down its trees to build warships,with which to gain itself an empire.It gained the empire but,without its trees,its soil became bare and poor.When the empire fell to pieces,the country found itself faced by flood and starvation.Even though a government realizes the importance of a plentiful supply of trees,it is difficult sometimes to make the people realize this.They cult down the trees but are too careless to plant and look after new trees.So,unless the government has a good system of control,or can educate the people, the forests slowly disappear.This does not only mean that there will be fewer trees.The results are even more serious:for where there are trees,their roots break the soil up,allowing the rain to sink in and also bind the soil.This prevents the soil from being washed away.But where there are no trees,the rain falls on hard ground and flows away on the surface,and this causes floods and the rain carries away the rich topsoil in which crops grow.When all the topsoil is gone,nothing remains but worthless desert.16.Trees are useful to man mainly in three ways,the most important of which is thatthey can.A)make him draw quick profit from themB)keep him from the hot sunshineC)enable him to build warshipsD)protect him from droughts and floods17.It's great pity that.A)man hasn't found out that he has lost all tressB)man is eager to profit from treesC)man hasn't realized the importance of trees to himD)man is only interested in building empires18.Sooner or later the forests will disappear unless.A)all people are taught the importance of planting treesB)a country has a plenty supply of treesC)the government punishes those who cut trees instead of planting themD)people stop cutting down their trees19.The word"bind"in paragraph5means.A)to wash awayB)to improveC)to make stay togetherD)to make wet20.When there is a heavy rain,trees can help to

2018年河北省专接本英语考试真题2018 Hebei Province College English Test for Specialty TransferPart I Reading comprehension (30 points)Directions: There are three passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet.Passage 1Questions 1 to 5 are based on the following passage:We like to think that today's technological wonders are entirely our own creation. But a new study suggests that the human brain has been building networks of personal computers for over 50,000 years." Long before we had computers, long before we had a written language, we were using technology to store information outside our bodies, " says Chet Sherwood, a physical anthropologist at George Washington University.Sherwood made an analysis of the brain of a Neanderthal, an extinct species of them last shared a common ancestor with man some 300,000 to 400,000 years ago. We often associate the Neanderthals with a lack of mental power and language, but Sherwood's findings suggest that they were ahead of their time." You can't really use the Neanderthals as a punch line anymore," Sherwood says, "There is clear evidence that they were at least attempting literacy in some manner.In the view of course, they were technology geeks of their day. They built tools, mastered fire, and organized their out-of-body information network using tree bark and bone."Sherwood's team put a cast of the brain cavity of a150,000-year-old Neanderthal alongside one of a modern human. It found that Neanderthals had larger brains than humans. Sherwood believes their brain was built not only for complex thoughts, but was also structured to accommodate the laborious steps of literacy.Converting oral information into something written is a technology almost as complex as building a computer network.Neanderthals, it seems, were walking around with a lot more technology than we ever got them credit for - especially giventhat their tools were, in evolutionary time satellite, less than a blink of the eye away from today's computers.1. What does the passage mainly discuss?A. Information technology.B. The history of literacy.C. The brain of a Neanderthal.D. The technology of the Neanderthals.2. The word "punch" (Line 9) could best be replaced byA. jab.B. exclamation.C. applause.D. humor.3. What does Sherwood suggest in the passage?A. Computers are a natural evolution of writing.B. Computing power is a recent human novelty.C. The Neanderthals likely had a written language.D. Neanderthals possessed modern-like computers.4. What does the passage say about the Neanderthals' brain size?A. It was smaller than that of early humans.B. It was unsuitable for literacy.C. It was not as large as that of modern humans.D. It was larger than that of modern humans.5. According to the passage, what can be said about Neanderthals?A. They were relatively unintelligent.B. They used tools.C. They were not technology geeks.D. They used oral information networks.根据以上文章完成以下问题1. 整个文章主要讨论什么？2.第9 行的“punch”一词最好用什么词来代替？3. 文章中谢尔伍德暗示了什么？4. 文章谈到了尼安德特人的大脑尺寸吗？5. 根据文章，关于尼安德特人，哪个说法是正确的？Passage 2Questions 6 to 10 are based on the following passage:You cannot see the beauty of Beijing in winter by taking only daytime tours. Beijing at night is simply stunning. A night stroll along the streets or a night view from a high hill offers visitors quite a different impression. Beijing night exists in two opposite forms: ancient and modern. If you walk through the narrow alleys of a fading old street in the Shichahai area or the Forbidden City at nightfall, you could easily get lost and feel like you have traveled back in time to Yuan, Ming or Qing Dynasties of China. Modern pavilions with colorfully painted windows provide quite a contrast to the surrounding dark grey bricks. The detour to the narrow Longfusi embedded in the hutongs (alley ways) in Dongcheng District can also help you get a better understanding of the history of old Beijing. Night scenes of the forbidden City, especially of light reflections in the shichahai Lakes and Beihai Park, are extremely charming. Pay special attention to the reflections of the old Chinese wooden architecture during your walks.Those who love excitement will feel the charm in the modern form of night life in Beijing. The impressive nightscape of Beijing is worth spending an evening to enjoy. The modern night life usually happens in the inner city areas where modern bars, discos, and amusement parks abound. When you walk around the central business district Wangfujing and Guomao, you will bedazzled by neon lights, glamours shops and abundant luxurious cars driving through – Beijing at night is Beijing at its most modern. The bird's eye view of night Beijing from the central television tower or the international Club will impress you so much that it seems to be too beautiful to be true.6. What is the main idea of the passage?A. The best time to visit Beijing.B. Traditional Chinese architecture.C. Beijing's night-time charm.D. Beijing's modern nightlife.7. The word "abound" (Line 14) is closest in meaning toA. disappear.B. lack.C. rest.D. be plentiful.8. Which of the following would NOT be a place to experience modern night life in Beijing?A. The international Club.B. Wangfujing.C. The Forbidden City.D. Guomao.9. According to the passage, what contrast is there in Beijing's night scene?A. Neatness versus disorder.B. Modernity versus tradition.C. Light versus darkness.D. Large versus small buildings.10. What is it about the old wooden architecture that the author wants tourists to pay attention to?A. Its age.B. Its paint.C. Its reflections.D. Its color.。
