______ that distinguish human beings from mother primates are related to the ability of people to sand upright and walk on two legs.
A. many of the physical characteristics
B. of the many physical characteristics
C. the physical characteristics
D. there are many physical characteristics
答案是 A。我想选择 D,我认为后面是 that 引导的从句,空格处应是主句,而 D 主谓俱全,所以是 D。请问这道题我的问题出在哪里呢?
A 正确,D 错误。分析如下:
1. many of the physical characteristics...are related to the ability of people to sand upright and walk on two legs.是主句,其中 many of the physical characteristics 是主语;如果再细分,不定代词 many 是主语,介词短语 of the physical characteristics 是定语,修饰 many。
2. that distinguish human beings from mother primates 是定语从句,修饰the physical characteristics。
