people from the West like to use “please” and “thank you” in cases ________ some people in Asia may not think ________ necessary.

A．that；it                                                    B．when；that

C．where；it                                                 D．what；/

【回答】

C

【解析】

先行词为case、point、situation等表抽象地点的名词时，定语从句要用where来引导。第二个空考查it作形式宾语，necessary后面省略了真正的宾语to use “please” and “thank you”。故选C。

【名师点睛】当先行词是situation，case，point等词时，后常用where引导定语从句。例如：Have you ever had a case where someone accused your journalists of getting the wrong end of the stick? 所谓形式宾语即是it，it作形式宾语需具备两个条件，一是真正的宾语是不定式、动名词或从句；二是有宾语补足语，具备了这两个条件，形式宾语it一定要用。如本句中真正的宾语是to use “please” and “thank you”，在此省略；句中有补足语necessary，故用it。
