It is better to have half of ___than nothing at all.

6个回答

  • 选B

    It is +形容词/比较级、最高级+to do sth.这个基本句型是It 作形式主语,不定式是真正的主语

    have half of ___这部分就是不定式部分,缺宾语,B是由what 引导的宾语从句满足.而C/D都需要先行词才能构成定语从句,A 选项做宾语从句缺宾语.

    另外,后面一个部分than nothing at all实际上是省略了 than (to have ) nothing at all,因为than需要连接两个对等的结构
