主语 + 动词 + 宾语 + 宾语补足语 句型中,常用 it 作先行宾语,真正的宾语为后面的动词不定式或从句。
使用条件
- 结构:主 + 谓 + 宾 + 宾补
- 宾语过长:影响到了补语,所以使用it做为形式宾语占位置。
常用这种结构的动词有:find,think,consider,feel,make,keep 等:
- People are going to find it difficult to get to work. 形式宾语it,真正的宾语to do
- She felt it right for them to arrest the thief.
- They consider it impossible to finish the work in three days.
