Passage 1 Questions 1 to 5 are based on the following passage: Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares(噩梦). (76)Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase(抹去), the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. (77) So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased. The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories. “Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions.” said Roger Pitman, a professor of psychiatry at Harvard Medical School. “This could relieve a lot of that suffering.” But those who are against the research say that it is very dangerous to change memories because memories give us our identity. They also help us all avoid the mistakes of the past. “All of us can think of bad events in our lived that were horrible at the time but make us who we are. I’m not sure we want to wipe those memories out,” said Rebecca Dresser, a medical ethicist. The passage is mainly about _____.

A. a new medical invention
B. a new research on memories
C. a way of erasing painful memories
D. an argument about the research on the pill

For example, the weed Crepis Sancta, found in France, has two types of seed, heavy and fluffy. The heavy ones land near the parent plant, whereas the fluffy seeds float further away on the wind. In urban environments, seeds that float far often land on infertile concrete. Within about 5-12 generations the weed has been found to evolve to produce significantly more heavy seeds than its rural relatives. Among vertebrates, a case is urban great tits, which have been found to sing at a higher pitch than their rural relatives so that their songs stand out above the city noise, although this is probably a learned rather than evolved response. Urban silvereyes, an Australian bird, make contact calls that are higher frequency and slower than those of rural silvereyes. As it appears that contact calls are instinctual and not learnt, this has been suggested as evidence that urban silvereyes have undergone recent evolution so as to better communicate in noisy urban environments. Many North American species have successfully adapted to urban environments and are thriving. Typical examples include coyotes, rabbits, raccoons, squirrels,opossums, deer and red foxes. This has led to conflict with humans, as these animals open garbage bags in search of food, eat food left out for pets, take the pets themselves, feed on prized garden plants, dig up lawns, and so on. There may be some concern that coyotes pose a risk to small children and that they should not be left unsupervised in areas where coyotes are known to inhabit. While there are media accounts of alligators being found in sewer pipes and storm drains, most experts think that such ’sewer alligators’ are unlikely to sustain a breeding population in such an environment.Animals known to dwell within human habitations include house mice, cockroaches, house centipedes
