英语语法第七讲非谓语动词.ppt

高考总复习·人教版·英语 语法专题复习　 第七讲　非谓语动词 考点透析 1．不定式、分词、动名词的否定式都是在其前面加 not /never。 (1)Mrs.Smith warned her daughter never to drive after drinking. (2)Not knowing what to do, I want to the teacher advice. (3)I apologize to you for not telling you the truth immediately. 2．不定式的进行时表示动作与谓语动作同时发生。不定式、分词、动名词的完成式表动作在谓语之前发生。 (1)When mother came into the room，Sid pretended to be working hard at his lesson. (2)Robert is said to have studied abroad, but I don’t know what country he studied in. (3)Having finished all my homework, I went out to play football with Li Ming. (4)The boy was severely punished by his father for having told lies. 3．不定式做定语时，如果不定式是不及物动词，或者不定式所修饰的名词是不定式动作的工具、地点，不定式后就应有必要的介词。 There are five pairs to choose from，but Im at a loss which to buy. 4．不定式主动表被动的几种情况： 在 There be结构中，做定语的不定式既可用主动语态也可用被动语态。 There is a lot of work to do/ to be done. 不定式做定语时，如果不定式所修饰的名词是不定式的宾语，但是又可在句子中找到另一个词做不定式的逻辑主语，不定式要用主动语态。 Would you please give the boy something to read? (something是 read的宾语，the boy是 read的逻辑主语，不定式用主动语态。) 注意比较下列两个句子： I have some letters to type. (I will type the letters myself.) Do you have ant letters to be typed, sir? (I will type the letters for you.) 5．关于不定式的省略 在连词than，as后、介词except，but，besides后，如果前有实义动词do的某种形式，动词不定式一般不带to，反之则带to。 (1)In that case，there is nothing you can do than wait. (2)He like reading novels besides to play the piano. 使役动词make, let, have和感官动词see, watch, hear, observe后接不定式做宾补时要省to，但在被动语态中，to不能省。 (1)A computer does only what thinking people have it do. (2)Paul doesn’t have to be made to learn. He always works hard. 6．admit，advise，avoid，appreciate，cant help，consider，delay，deny，escape，enjoy，finish，feel like, fancy，imagine，mind，miss，practise，risk，suggest等动词以及所有带介词的短语动词后面只能跟动名词做宾语。 (1)I really appreciate having time to relax with you on this nice island. (2)The boy was lucky enough to escape being punished. 7．remember，forget，try，mean，regret，stop，go on后接不定式做宾语与接动名词做宾语，意义有很大区别，必须牢记。 regret doing因做过某事而后悔，动作已发生
