If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Todays leading killers, such as heart diseases, cancer, and aging itself, will become distant memory. In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on-in much the same way our bodies make new skin cells to take the place of old ones. It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.36. According to the passage, human death is now mainly caused by _.A. diseases and aging B. accidents and warC. accidents and aging D. heart diseases and war37.

Humans may live longer in the future because _.A. heart disease will be far away from us B. human brains can decide the final deathC. the basic materials of cells will last forever D. human organs can be repaired by new medicine39. We can learn from the passage that _.A. human life will not last more than 120 years in the futureB. human have to take medicine to build new skin cells nowC. much needs to be done before humans can have a longer lifeD. we have already solved the technical problems in building new cells.BAvocados are large, heavy, dark green fruits that are usually shaped like pears. The riper they get, the softer they get. People eat avocados in salads and sandwiches. But probably the most popular way to use avocados is in guacamole, a delicious Mexican snack(小吃). Inside the fruit is a very large seed(种子), which you can use to grow a tall, beautiful avocado plant.1. Wash the avocado seed with cold water. Stick four tooth-picks around the middle of the seed.2. Fill the jar almost to the top with water that is just slightly warm. Rest the toothpicks on the top of the jar. The more pointed end of the seed should be in the water while the flatter end should face upward.3. After that, you will have to wait for three or four weeks. During that time, be sure to add just enough water to replace the water that evaporates into the air. The bottom of the seed should always be just below the waters surface. The thin brown skin that covers the seed will crack(破裂) open. Roots will start growing out of the bottom of the seed. Leaves will start growing at the top. 4. When the roots are about three inches long, fill a flowerpot with soil and plant the seed. Make sure that the seed is completely covered by soil and that the young leaves are above the soil. 5. Find a sunny spot for the plant. Water it every few days to keep the soil moist (潮湿的). Watch it during the next few months. Your avocado plant will grow a tall, straight stem (茎) and large oval leaves.41. The main idea of the first paragraph is to _.A. tell us how to grow an avocado plant B. give us a brief introduction to avocadosC. tell us the shape and color of avocados D. tell us that avocado is a fruit42. Which of the following statements is NOT true according to the passage? A. The two points of the seed are of the same shape. B. The soil in the flowerpot should neither too dry nor too wet. C. Wed better use ripe avocados to make some guacamole. D. The most popular way to use avocados is in guacamole.43. The word “evaporates” in the fourth paragraph means _. A. turns into ice because of cold weather B. becomes very hot by the sun heat C. turns into other things because of chemical change D. becomes vapor and disappear44. How long will the thin brown skin that covers the seed crack open? A. 1 or 2 weeks. B. 2 or 3 weeks. C. 3 or 4 weeks. D. a few days.根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool?
