中考英语动词不定式考点全攻略

中考英语动词不定式考点全攻略 动词不定式历来是中考英语命题的热点之一。它是动词的一种非谓语形式,没有人称和数的变化,不能单独作句子的谓语。其构成形式为"(not)to+动词原形"。 考点攻略一:动词不定式作主语 1)动词不定式直接用在主语位置:To see you is always a pleasure. 2)如果主语较长,则可以用it作形式主语,而将真正的主语(不定式)置于后面。 ①It is +形容词+(of sb.) to do sth. 此处常用careless, clever, foolish, honest, kind, nice, rude, stupid, silly, wrong, wise等形容词,与介词of搭配,这些形容词常表述不定式逻辑主语的属性或性质。 It’s brave of you to jump into the river to save the boy! ②It is +名词或形容词+ (for sb.)to do sth. 此处常用necessary, hard, difficult, easy, important, impossible等形容词,与介词for搭配,表示不定式的动作或行为的性质。 It is our duty to keep our classroom clean. It is important for us to protect the environment. ③It takes sb. some time to do sth. It usually takes us about two and a half hours to travel from Shanghai to Japan. 考点攻略二:动词不定式作宾语 其后常接不定式作宾语的动词有:agree, afford, choose, decide, expect, plan, promise, manage, hope, wish, want, seem, refuse, fail等。 I didn’t expect to see you here. 在某些复合宾语中,动词有find, consider, think, make, feel,常先用it代替不定式,作形式宾语,而把不定式放到后面去。 I find it impossible to finish the task on time. 考点攻略三:动词不定式作宾语补足语 动词不定式作宾补,即“动词+宾语+(not)to do sth.”,接不定式作宾补的常见动词有:advise, allow, ask, cause, expect, beg, encourage, get, help, invite, teach, order, remind, tell, want, wish, warn等。 My parents always tell me not to be late for school. 考点攻略四:动词不定式作表语 不定式作表语一般位于系动词之后,表示具体动作,特别是表示将来的动作;若主语是aim, duty, hope, idea, job, plan, problem, purpose, wish等名词,不定式作表语是对主语起补充说明作用。 It is said that they are to visit China next month. My wish is to become a scientist like Einstein. 考点攻略五:动词不定式作定语(常用于名词之后)。 由only, last, next,序数词或形容词最高级修饰的名词常用不定式做定语, Tom is always the first student to arrive at school. 注:动词不定式to后所接动词若是不及物动词,而不定式与其修饰的词之间有动宾关系时,此不定式后要加相应的介词。 We haven’t decided which hotel to stay at. I need a pen to write with. 考点攻略六:动词不定式作目的状语。如: To keep fit, students are advised to do morning exercises. so as to (不可用于句首使用),in order to也可以引导目的状语。
