        1. 【題目】1 think________is important for us to help our parents do housework during the holiday.

          A.thisB.thatC.itD.what

          【答案】C

          【解析】

          句意:我認(rèn)為在假期幫助父母做家務(wù)對(duì)我們來說很重要。

          考查It作形式主語。本句為含有賓語從句的主從復(fù)合句,從句中的句型結(jié)構(gòu)為it is +adj+for sb+to do sth,表示“對(duì)于某人來說,做某事是如何的”,it在句型中作形式主語。真正的主語是“to help our parents do housework”。故選C。
