高一英语北师大版必修一Unit 1 Life Choices单元语法一、动词不定式作主语、宾语、定语、表语、状语和宾补1.作主语动词不定式可起名词的作用,在句中作主语,谓语动词用单数。
To live is to do something worthwhile.活着就是要做有价值的事情。
To see is to believe.眼见为实。
注意:在实际运用中,通常是用it作形式主语,而把真正的主语(不定式)后置,尤其是当作主语的不定式结构很长的时候。
It is important to develop the right habits. 养成正确的习惯很重要。
2.作宾语动词不定式可以充当部分及物动词或短语动词的宾语,也可以充当部分介词的宾语。
(1)用动词不定式作宾语的及物动词很多,又以表示决心打算、喜爱或讨厌之意的动词居多。
常接不定式的及物动词有hope/wish/expect/long,agree/promise/undertake,intend/plan/want/mean/desire,arrange,manage,learn,decide/determine,attempt,pretend,chooseoffer,demand,refuse,threaten,prepare,fail等。
(2)it作形式宾语:当不定式作某些需要有宾语补足语的动词的宾语时,要用it作形式宾语,而把作真正宾语的不定式放在补语后面。
(3)作介词的宾语:这样的介词不多,常见的有but,except(除了)和besides。
当这些介词前有实义动词do及其各种形式时,介词后面的动词不定式通常省略to。
They could do nothing but wait for the doctor to come.他们只好等医生来。
The teacher made no comments except to tell him to work hard.老师除了叫他努力学习外,什么也没说。
