Question

He dressed up and went to the party as if ________.

A．was invited

B．had been invited

C．to be invited

D．invited

Answer 1

D

试题分析：句意：他盛装去参加了聚会好像他被邀请似的。这里as if后是省略句，完整的是as if he was invited这里省略了he was，省略的条件是从句的主语与主句的主语一致，并且从句的谓语动词里有动词be,这时从句的主语与be都省去，故选D。
点评：本题难度适中。状语从句的省略是高中应该掌握的语法项目，需要考生牢记省略的各种情况。这里考生容易误选A，这里提醒考生注意从句的主语与be都要一起省去。
即学即练:He is rather difficult to make friends with, but his friendship，_______is more true than  any other.
A.once gained                          B.when to gain
C.after gaining                        D.while  gaining
解析：A。once gained =" once" it is gained。当状语从句的主语和主句的主语一致且从句中含有be动词时，可省略从句中的主语和谓语部分。
