關(guān)于不定式用法講解,不定式用法這個(gè)問題很多朋友還不知道,今天小六來為大家解答以上的問題,現(xiàn)在讓我們一起來看看吧!
1、不定式作定語的用法不定式及其短語作定語,與其他短語作定語一樣,一般都放在被修飾的詞之后,通常表示一個(gè)將來的動作,有時(shí)也可以表示某一過去的特定動作。
2、 一些名詞后常用不定式作定語,如:chance(機(jī)會),way(方法),time(時(shí)間)等;另外,the first,the second,the last,the only等作名詞或者它們作形容詞用來修飾代詞,它們或它們所修飾的代詞后,也常用不定式作定語。
3、不定式作定語時(shí),不定式與被修飾詞之間存在的關(guān)系復(fù)雜,有的是主謂關(guān)系;有的是動賓關(guān)系;有的是動狀關(guān)系,還有的不存在主謂、動賓、動狀關(guān)系。
4、主謂關(guān)系的(1)We must find a person to do the work. (2) There is no one to take care of her. (3) In my family,my mother is always the first one to get up. (4) He is always the first to come and the last to leave. (5) We need someone to go and get a doctor. 2、動賓關(guān)系的 如果不定式與被修飾的詞在邏輯上存在動賓關(guān)系,不定式里的動詞必須是及物動詞。
5、注意:是及物動詞的,后面不要再加賓語,因?yàn)榍懊娴谋恍揎椩~是它的賓語;是不及物動詞的,要加上適當(dāng)?shù)慕樵~或副詞讓它變成及物動詞,只有這樣,它才能帶上前面的賓語。
6、(1) He has a lot of books to read.(2) I would like a magazine to look at.(3) Here is some advice for you to follow.(4) Do you have anything else to say?(5) There is no one to take care of.(6) She has nothing to worry about.3、動狀關(guān)系的 被修飾詞如果是不定式里動詞的狀語,應(yīng)多用介詞短語。
7、由于被修飾詞前沒有介詞,所以只能在不定式里的動詞后加介詞。
8、(1)Please give me some paper to write on. (2) Let"s find a room to put these things in (3) I have no house to live in. (4) He has no pen to write with.(5) There are five pairs to choose from.4、不存在主謂、動賓、動狀關(guān)系的 被修飾詞與不定式里的動詞不存在主謂、動賓、動狀關(guān)系的,被修飾詞多是些抽象名詞。
9、 (1)I have no time to go to the movie.(2)There"s no need to send for a doctor. (3) Where"s the best place to meet? (4) Is that the way to do it?(5) I"m not sure about his ability to complete the task alone.。
