No other animals have all three parts to work to gether. No animals can do what human beings can do. Humans can do many things and feel many things with the hand. The h and can hold onto things and make things because the thumb works with the fingers. This fifth finger is strong. Most animals d on’t have thumbs. The thumb can press against the other finger s. Without a thumb to press against the fingers, it is difficult to hold onto anythin g. The thumb and fingers can also fit the flat surface of a box an d the curved (不平的) surface of a pencil. We can feel that something is hot or col d, soft or hard, smooth or rough. The hand, with thumb and fing ers, is one of the best tools we have. Most animals see a flat pi cture. Their eyes can only see how high and how wide somethi ng is. Some animals see a different picture with each eye. Som e don’t see in colour. Humans see one picture with both eyes w orking together. We can see how high and how wide something is. We can also see how far in front of or in back of something a thing is. The brain tells other parts of the body how to work. S ome of the things the body does are automatic; that is, we don’t have to think about them. For example, wedon’t have to think to make our heart eat or our stomach work. The brain tells the eyes and hands how to make useful and beautiful things. That is how human beings become tool makers an d artists. That is how human can have richer and better lives than other animals.36. Human beings are different from other animals because ___ ________.A. human beings have the hands, the eyes, and the brain wor king all the timeB. other animals also have hands, the eyes, and the brainC. human beings work together with other animalsD. the hands, the eyes, and the brain of the human can work t ogether37. According to the passage, when you say you hold onto som ething, you mean___________.A. you have it in your hand and keep it there by putting your fi ngers firmly round itB. you have it in your arms and keep it there by putting your fi ngers firmly round itC. you feel it with your handsD. you press the fingers of your right hand against those of yo ur left hand38. The author tells us that no animals can do what humans can do. He gives quite a few facts to support the idea. One of the m is that ___________.A. most animals don’t see in colourB. the humans see a thing with both eyes working togetherC. only humans can see and how high and how wide a thing i sD. some animals can see only one picture39. ___________ is automatic.A. BreathingB. Driving a carC. Making a chairD. Playin g footballBThe old shoes had brought him so much trouble that Johnny de cided to throw them away. He went to the rubbish pit (垃圾坑)outside the city and threw the old shoes into the pit. "Now th ey can bring me no more trouble," he said. He returned home, l ay down in his bed and slept. But he had a dog, and the dog wa s used to going to the rubbish pit to look for food, because John ny never bought food for his dog. The dog, who loved its master (主人) even though it was not given food, saw the shoes in the pit and knew they were its master's. So the dog took one of the he avy shoes in its mouth and went slowly back with it, and left it atits master's bedside. Then the dog fetched the other shoe in th e same way. When Johnny woke up, he saw the shoes by his b ed and he was afraid. "There, shoes can walk by themselves, th ey must be done away with." he thought. Then he made a large fire in front of his house and put the shoes on it. Just then a str ong wind was blowing and before long the fire made the house begin burning. His neighbours immediately came but could do n othing. The house burnt down but the old shoes were saved by the dog again.40.

It wasat Lakeside that Gates began his career in personal puter soft- ware, programming puters at age 13.In 1973, Gates entered Harvard University as a freshman, where he lived down the hall from Steve Ballmer, who is now Microsoft's president. While at Harvard, Gates developed a version (版本) of the programming language BASIC for thefirst microputer---the MITS Astair. In his junior year, Gates dropped out of Harvard to devote his energies full-time to Microsoft, a pany he had started in 1975 with his boyhood friend Paul Allen. Guided by a belief that the personal puter would be a valuable tool on every officedesk-top and in every home, they began developing software for personal puters.Gates' foresight has led to the suess of Microsoft and the software industry. He plays an important role in the technical development of new products. Much of his time isdevoted to meeting with customers and staying in touch with Microsoft employees around the world through e-mail.In the dozen years since Microsoft went public, Gates has donated more than $ 800 million to charities (慈善机构), including $ 200 million to the Gates Library Foundation to help libraries in North America make use of newtechnologies and the Information Age.1. Where did Bill Gates begin his career in personal puter software?A. At public elementary school.B. At the private Lakeside School.C. At Harvard University.D. At Microsoft Company.2. Why did he drop out of Harvard?A. To change school.B. To spend all his energies to Microsoft.C. To find a full-time job.D. To earn money.3. How does Gates spend much of his time?A. Meeting with people.B. Travelling around the world.C. E-mailing some friends.D. Meeting with customers and e-mailing Microsoft employees.4. What does the underlined word "donated" in the last paragraph mean?A. gave.B. earned.C. made.D. received.What are you doing right now? Yes, you are reading this page. That also means you're moving your eyes. You're thinking. You're breathing. You're listening. Possiblyyou're shifting(变换) positions. You're also feelingthings---this book, your chair, emotions. What lets you do all these things at the same time? Your brain.Your brain is the control center of your body and mind. Without your brain you can't do anything. Your brain has more than 100 billion nerve(神经) cells. Each nerve cell makes from 1,000 to 10,000 connections with other nerve cells. The nerve cells send impulses back and forth in your brain and to and from every part of your body. After you reach the age of 20, though, your brain cells start to die. This is mon. However, if you suffer an illness, or injury, even more nerve cells die in your brain. When a nerve cell dies, the thousands of connections it made with other nerve cells are lost.Until recently, scientists believed that the brain did not replace its dead cells. New studies, however, prove not. Scientists have found new nerve cells in a part of thebrain called the hippocampus(海马区). The hippocampus helps the brain form memories from new experiences.The discovery of these new nerve cells is not a curefor anything yet. It gives hope, however, of a cure forbrain damage from such things as epilepsy(癫痫病), LouGehrig's disease, car aidents, and strokes. Someday scientists might be able to use the new cells to replace damaged brain cells. Such a cure, however, may take about ten years to develop. So at the same time, use your head---protect it!1. Nerve cells in the brain.A. send massages to every part of the bodyB. make connections only to other cells in the brainC. can cure Lou Gehrig's diseaseD. are a person's memory2. The last sentence of the passage suggests that people.A. should use their head by carefully thinking through situationsB. should be careful not to injure their brainsC. have a skull (头盖骨) that provides all the protection needed by the brainD. would see a quick cure for brain disease猜你感兴趣：1.2.3.4.5.6.。
