4 Three-fourths of the apples _______ ruined.
A) was

D) have
答案 B(是不是Three-fourths of the apple 的时候就可以用单数?)

Answer 1

1 The human body has certain materials in it which may kill the germs.是个which引导的定语从句,主句就是the human body has materials

2 由句意可得,学生的特点是“聪明，好问”。

3 主语从句Whatever is worth doing at all中的whatever就是doing的宾语，因此不能再加it。

4 原问中APPLES是复数,用WERE
Three-fourths of the apple 的时候就可以用单数
