Question

I would appreciate         if you could look after my pet while I am away.

A．you

B．this

C．it

D．myself

Answer 1

C

试题分析：考查it做形式宾语，句型是：appreciatee it if…,it 在这里做形式宾语这是个宾语从句！真正的宾语指if you could look after my pet while I am away，句意：如果我不在的时候你能帮我照顾我的宠物我会很感激的。选C。
点评：除了appreciate，还有like，hate，dislike等动词后面先接it再接从句，还有词组see to，depend on后面都是先接it再接从句。
