Grammar 1. 不定式与动名词 动名词表示一般或抽象的动作，而不定式则往往表示 具体或一次性的动作。 2) 某些动词后只能接不定式作宾语， 如： afford, ask, decide, demand, expect, plan等； 而另一些动词后 需接动名词作宾语， 如： enjoy, finish, avoid, consider, mind, deny, risk等。 3) 有些动词后既可接不定式也可接动名词， 但二者意义有较大的区别， 如： forget， stop， remember， regret， try等。 Grammar 2. 不定式与分词 很多动词后接不定式作宾语补足语， 如： ask, encourage, allow, cause, invite, request等。 2） 感官动词feel， see， watch， hear等和使役动词have， let， make后既可接分词也可接不带to的不定式作宾语补足语。 接现在分词 （present participle） 表示动作正在进行， 接过去分词 （past participle）表示被动， 接不定式表示动作已经完成。 →I heard her singing an English song when I passed by her room yesterday. →I heard her sing an English song just now. →I heard the English song sung many times. 3) 不定式和分词在句中可以作状语。 不定式作状语主要表示目的或结果， 分词作状语表示时间、 原因、 方式、 条件等。 现在分词与句子主语是主动关系， 过去分词与句子主语是被动关系。 →To hide my emotion, I buried my face in my hands. →Not knowing what to do, he went to his parents for help. →Given more attention, the trees could have grown better. Grammar 3. 动名词和现在分词 动名词和现在分词作表语时，动名词表示主语的具体内容，主语和表语 的位置常常可以互换；现在分词表示
