Scientists must communicate their message to the public in a compassionate, understandable way -- in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother’s hip replacement, a father’s bypass operation, a baby’s vaccinations, and even a pet’s shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst.
在該段段尾,句子wasteful at best and cruel at worst.中含有與選項(xiàng)句式結(jié)構(gòu)(即A and/but B)相近的句式結(jié)構(gòu),即“inhuman and unacceptable(不人道的、不能接受的) ”,它是選項(xiàng)B的同義替換,所以正確答案是B。
又如:(真題閱讀2008年Text 1)第28題,它的四個(gè)選項(xiàng)的句式結(jié)構(gòu)是:A and B。
28.According to Paragraph 4, the stress women confront tends to be
A. domestic and temporary(家庭的、臨時(shí)的)
B. irregular and violent(不規(guī)律的、暴力的)
C. durable and frequent(持久的、經(jīng)常的)
D. trivial and random(瑣碎的、隨機(jī)的)
[解析]:該題沒有明確的定位信息,只能定位到段落上,即第4段,該段內(nèi)容如下:
Dr. Yehuda notes another difference between the sexes. “I think that the kinds of things that women are exposed to tend to be in more of a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family members, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating.”
在該段中,很容易找出,chronic or repeated(長期的、反復(fù)的)是A and/or B結(jié)構(gòu),它是選項(xiàng)C的同義替換,所以正確答案是C。
