【华慧考博】考博英语每日一练(12.10)参考答案
1.D【句意】我首次在会议上遇见她时,她可能50岁左右。
【解析】语法题——“must have been”表示对过去事实的肯定推测。由句中关键词“fifty or so 50岁左右”与“when I first met her at the conference”的对应知这里表示对已发生的过去情况的一种推测,故D项“must have been”正确。
2.C
【句意】我了解到这个地区没有真正本土的动物,这里所有的动物都是从外地引进的。
【解析】形容词词义辨析。endangered“濒临灭绝的;有生命危险的”;domesticated“家养的;驯服的;喜欢家庭生活的”;indigenous“ 本土的;土著的;国产的;固有的”;extinct“灭绝的,绝种的;熄灭的”。由句中关键词“no genuinely没有真正”“all the animals were brought here from other places这里所有的动物都是从外地引进的”的对应知“本土的”符合语境,故C项正确。
