　　2022年6月英语四级备考必备语法知识(2)

　　短语部分没有独立主语，则短语结构称为非谓语动词。

　　非谓语动词的结构：分词(分词短语)

　　句子的主语决定非谓语动词中的分词是用主动还是被动形式。如果是句子的主语发出动作，则使用现在分词;如果动作不是由句子的主语发出，则使用过去分词。

　　1.No matter how frequently _A_， the works of Beethoven always attract large audiences.

　　A performed B performing C to be performed D being performed

　　perform vt. 表演，演出，演奏;

　　to be performed 将要被演奏; being performed 正在被演奏;

　　一些特殊的动词：

　　第一点：forget 忘记; [反义] remember 记得;

　　这两个词后加动词不定式表示将要进行的行为;这两个词后加动词ing形式表示已经做过的事情。

　　注意：动名词与现在分词形式一样，但含义不同。这两个词后加动词ing形式都是动名词。

　　forget to do sth. 忘记要去做某事; forget doing sth. 忘记做过某事;

　　remember to do sth. 记得要去做某事; remember doing sth. 记得做过某事;

　　2. I remember _B_ to help us if we ever got into trouble.

　　A once offering B him once offering C him to offer D to offer him

　　offer vt. 提出，提供; offer sb. sth. / offer to do sth.

　　him once offering 如果改成 his once offering 也正确。

　　动名词的复合结构：凡是一个动词的后面可以加动名词，就可以加动名词的复合结构。

　　动作发出者 + 动名词;当动作发出者名字给出时：名词所有格 + 动名词;当动名词的复合结构在文章中出现，且动作发出者在前文中提过时：形容词物主代词(宾格)+ 动名词。

　　形容词物主代词：his， her， my， your， their， our。代词宾格：him， her， me， you， us， them。

　　第二点：want 想要; want to do sth. 想做某事; want doing 客观需要或缺乏。

　　A to erect B be erected C erecting D being erected

　　watch 看电视用，看比赛用; see 看电影用;

　　感官动词watch， see， hear; 感官动词 + 名词(代词)+ do

　　be erected 强调的是动作的结果; being erected 强调的是动作的过程。

　　2. The engine _D_ smoke and steam.

　　A gives up B gives in C gives away D gives off

　　give up 放弃; give in 屈服，让步; give off 释放，放出(烟和气体);
