接词有：

1、如果as if引导的从句是“主语＋系动词”结构，可省略主语和系动词，这样as if后可接名词、不定式、形容词（短语）、介词短语或分词。如：He acts as if（he were）a fool．他做事像个傻子。

2、as if从句用陈述语气的情况。当说话者认为句子所述的是真实的或极有可能发生或存在的事实时，可接现在分词。如：It sounds as if it is raining．听起来像是在下雨。

3、从句表示与过去事实相反，谓语动词用“had+过去分词”。如：He talks about Rome as if he had been there before．他说起罗马来好像他以前去过罗马似的。

■as if 后面可以接不定式、现在分词、过去分词。但是，这种用法实际上是 ‍as if 从句的省略形式。例如：
(1) He opened his mouth as if to speak.
= He opened his mouth as if he wanted to speak.
(2) He shook his head as if to say "no".
= He shook his head as if he wanted to say "no".
(3) She lifted one arm, as if to shield herself, then screamed in terror.
= She lifted one arm, as if she wanted to shield herself, then screamed in terror.
■如果 as if 从句的主语和主句的主语一致而且从句的谓语含有 be ，常常可以把从句的主语和 be 一起省略。例如：
(1) He stoodas if rooted to the ground.
= He stood as if he was rooted to the ground .
(2) He paused as if expectingLanny to speak.
= He paused as if he was expecting Lanny to speak.
