［辨错思路］ 1.首先要分辨动词的谓语形式与非谓语形式。如果题句中有两个动词形式划有横线,考生要分析句子的结构和语义,判断出哪个是谓语,哪个是非谓语,因为一个简单句或分句中不可能出现两个彼此间无连词连接的谓语。 2.在判定某个动词形式应为非谓语后,要辨别其应当是不定式,还是-ing形式或-ed分词。 3.在确定某一非谓语形式后,还要审查其时态语态是否有误；一般说来,已经发生了的动作用完成式,与逻辑主语的关系是受动,用被动态或过去分词。 4.注意非谓语动词的否定式是将否定词置于非谓语动词之前；据此判断否定词的位置是否有误。 5.观察分析句中的时间状语是修饰谓语动词,还是修饰非谓语动词,如果是后者,辨其时态是否有误。 6.不定式和分词的逻辑主语一般是句子的主语,否则不定式的逻辑主语应视情况用for, of引导,分词应有自己的逻辑主语,据此判断是否存在垂悬分词的错误。 ［改错要领］ 1.注意动词的不同接续要求。下列动词要求接不定式作宾语： afford, agree, attempt, decide, fail, manage, expect, intend, hope, mean, plan, promise, refuse, tend, pretend, ask, claim, offer, determine, arrange. 2.熟记下列动词要求接动名词作宾语： acknowledge, admit, appreciate, avoid, consider, delay, dislike, hate, deny, enjoy, escape, excuse, fancy, favour, finish, include, resent, keep, mind, miss, postpone, practise, resist, stand, risk. 3.掌握某些动词不同接续要求的不同含义： forget to do sth.忘记了去做某事 forget doing sth.忘记已做了某事 remember to do sth.记住要去做某事 remember doing sth.记住了已做某事 stop to do sth.停下去做某事 stop doing sth.停下在做的某事 regret to tell(say, announce)sb.遗憾地告诉某人… regret doing sth.对已做了的事表示后悔、遗憾 try to do sth.试图去做某事 try doing sth.试着做了某事 mean to do sth.打算做某事 mean doing意味着… 4.注意下列短语中的to是介词,后面应接动名词： object to, resort to, react to, contribute to, look forward to, be accustomed to, be used to, be committed to, be exposed to, be devoted to, be dedicated to, be opposed to, be contrary to, with regard to, with a view to, as to, in contrast to 5.注意下列后接动名词的习惯用法： ①It’s no use doing…但是：Its of no use to do… good picnic fun ②It is useless doing… senseless nuisance worthwhile ③There is no use(in)doing… point sense harm ④have difficulty doing… trouble problem ⑤have a good time doing… hard difficult ⑥spend(time) wastedoing… ⑦be worth doing… busy ⑧feel like doing… ⑨can’t help doing… 6.下列习惯用语中都带有but,后面都接不带to的不定式： can not help but do… can not but do… can do nothing but do… can not choose but do… can not do anything but do… 但是：have nochoice but to do… alternative 7.下列动词、介词后接动名词具有主动形式、被动含义,注意不要再用动名词被动态： sth. be worth doing比较：It’s worthwhile doing sth. past beyond sth. need doing want require demand bear deserve
