[单项选择] The trees arrived by post, a half-open parcel. They were thin-and straight, rather like arrows but with shiny leaves at one end and muddy roots at the other. Terry and his father took them down the garden and planted them in their prepared places. Terry had great hopes of the middle tree, now set in the memorial spot where Herry, his cat, run over, had been laid to rest a year before. The pine trees made an avenue down one side of the garden, where there was already a fifteen-foot stone wall between the garden and the back-yards of the Jenkins Street houses.
"Why do we want a row of trees as well as a wall " Terry asked his father.
His father said, " For privacy. These trees grow very thickly.
His father’’s love of privacy often puzzled Terry, who was not one to keep himself to himself, but he could see part of the point here. The houses in Jenkins Street were on higher ground. His friend Leslie lived in number twelve, and Leslie had only to stand on a box to see ri

[不定项选择题]共用题干
Chimpanzees
1 Chimpanzees(黑猩猩)will soon be extinct(灭绝).If the present rate of hunting and habitat(栖息地)destruction continues, then within 20 years, there will be no chimpanzees living in the wild. But this is more than an environmental or moral tragedy(悲剧).Chimpan-zee extinction may also have profound implications(含意)for the survival of their distant relatives一human beings.
2 In 1975 the biologist Marie-Claire King and Allan Wilson discovered that the human and chimpanzee genomes(基因组)match by ovet 98%. Compare this to the mouse, used as model for human disease in lab tests,which shares only 60% of its DNA with us.In fact, chimpanzees are far more similar to humans than they are to any other species of monkey. As well as resembling us genetically,chimps are highly intelligent and able to use tools.These facts alone should be enough to make protection of chimps an urgent priority(优先).But there is another,more selfish reason to preserve the chimp.
3 The chimpanzees' trump card(王牌)comes in the field of medical research. Chimpanzees are so similar to humans that veterinarians(兽医)often refer to human medical text-books when treating them. Yet chimpanzees do show differences in several key areas.In parti-cular,chimps are much more resistant to a number of major diseases.It is this ability that is so interesting.
4 For example,chimps seem to show a much higher resistance than humans to HIV,the virus that causes AIDS. Indeed,their use as experimental animals in AIDS research has de-dlined because they are so resistant.
5 By sequencing the chimp genome and pinpointing(找到)the place where the chimpanzee DNA sequence differs from that of humans,scientists hope to be able to discover which part of the genetic code gives chimps their increased resistance to some diseases. This,they hope,will allow them to develop new and more effective treatments for the human forms of these diseases. Such treatments could include the production of new drugs or even the alteration(改变)of the human genetic sequence. The recently completed human genome sequencing project has shown that such an effort is now well within our reach.
Scientists suspect that genes play a significant role in protecting chimps from getting______.
A.some human disease treatments
B.some diseases
C.human survival
D.human genomes
E.key areas
F.healthier lifestyle
