When I called up my mother on the phone she was upset about something happening to her. There were some snakes coming near the house now and then in our courtyard. But my mother didn’t know how to get rid of them. So, I felt very 20 (pride) to say that there was a chance for me to distinguish 21 (I)by inventing something merciful that would catch snakes 22 not harm them.
Prepared with some research findings, I decided 23 three approaches: firstly, removing their habitat; secondly, 24 (attract) them into a trap using male or female perfume or food; and thirdly, cooling them so that they would become sleepy and could be 25 (easy) caught. I decided to use 26 last one. I bought an ice cream 27 (make) which was made of stainless steel.
Between the outside and the inside walls of the bowl there is some jelly, 28 freezes when cooled. I put the bowl into the fridge and 29 (wait) for twenty-four hours. At the same time I prepared some ice-cubes. After adjusting my plan a few times, I collected the snakes and released them all back into the wild.

Some scientists now suggest that the cloning of humans could occur in the near future. Despite the benefits of cloning, however, certain ethical(道德的) questions concerning the possible abuse(滥用) of cloning have been raised. At the heart of these questions is the idea of humans influencing life in a way that could harm society, either morally or in a real physical sense. Some people object to cloning because it allows scientists to “act like God” in the handling of living organisms.
The cloning of Dolly raised the debate over this practice to a whole new level. It has become obvious that the technology for cloning Dolly could also be used to clone humans. A person could choose to make two or ten or a hundred copies of himself or herself by the same techniques used with Dolly. An active debate about the morality of cloning humans arises. Some people see benefits from the practice, such as providing a way for parents to produce a new child to replace one dying of a fatal disease. Other people worry about humans taking into their own hands the future of the human race.
At the beginning of the twenty-first century, many scientists say the controversy over the ethics of cloning humans is overstressed because of the unpredictability(不可预测性) of cloning in general. While scientists have cloned animals such as sheep, mice, cows, pigs, and goats, fewer than 3 percent of all those cloning efforts have succeeded. The animal clones that have been produced often have health problems. Scientists believe the rapid reprogramming in cloning can introduce random(任意的) errors into a clone’s DNA. Those errors have altered individual genes in minor ways, and the genetic defects(缺陷) have led to the development of major medical problems. Some scientists say this should make human cloning out of the question, but others argue that cloning humans may actually be easier and safer than cloning animals. Whatever, I agree that further research in the field of cloning is needed.
30. Some people are against cloning of humans because they think .
A. the practice takes too much time and money
B. the cloning technology is still not mature
C. humans control the future of the human race
D. the population in the world will be too large
31. Some scientists think the debate over ethics of cloning humans is overstressed because .
A. cloning of human beings is completely impossible
B. the result of cloning can’t be predicted in general
C. cloning of animals is a failure
D. there are big errors in a clone’s DNA
32. We can learn from the text that .
A. cloning of humans is a very controversial issue
B. the cloning of Dolly begins to raise the debate over cloning of humans
C. there are medical problems in cloning animals
D. cloning humans is easier and safer than cloning animals
33. The text is mainly about _______.
A. the benefits of cloning B. the ethics of cloning
C. the history of cloning D. the defects of cloning
六、七选五
Imagine that you are in a remote village somewhere with no medical clinic. 34 Once the doctors get to you, they examine you and take blood samples, but they won’t be able to help you until they take the samples back to the hospital to find out what is wrong. 35 Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic(诊断的) tool.
Ozcan’s invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don’t have enough training to correctly interpret what they see. 36 With Ozcan’s mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes.
37 His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.
By inventing a medical tool that uses existing technology — mobile phones — Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effectively almost anywhere. 38
A. Another reason that Ozcan’s invention is important is that it is inexpensive.
B. Even though you may only have a simple infection(感染), you might die because of the delay.
C. People are trying to reduce the cost of this new medical tool.
D. Ozcan’s simple, cost-effective tool might just save millions of lives around the world.
E. This tool has become much more popular all around the world.
F. You become very sick and must wait days until a mobile medical unit arrives to help.
G. As a result, they may diagnose illnesses incorrectly.
