2019屆高考英語基礎語法復習
only when we begin our college life do we realize the importance of english. 進了大學以后,我們才認識到英語的重要性。
說明: 引導此類倒裝句的副詞有never, seldom, rarely, little, only, so, well等。
6)用作代動詞。例如:
---- do you like beijing? --你喜歡北京嗎?
---- yes, i do. --是的,喜歡。(do用作代動詞,代替like beijing.)
he knows how to drive a car, doesn't he? 他知道如何開車,對吧?
4. 助動詞shall和will的用法
shall和will作為助動詞可以與動詞原形一起構成一般將來時。例如:
i shall study harder at english. 我將更加努力地學習英語。
he will go to shanghai. 他要去上海。
說明:在過去的語法中,語法學家說shall用于第一人稱,will 只用于第二、第三人稱。現在,尤其是在口語中,will常用于第一人稱,但shall只用于第一人稱,如用于第二、第三人稱,就失去助動詞的意義,已變為情態動詞,試比較:
he shall come. 他必須來。(shall有命令的意味。)
he will come. 他要來。(will只與動詞原形構成一般將來時。)
5.助動詞should, would的用法
1)should無詞義,只是shall的過去形式,與動詞原形構成過去將來時,只用于第一人稱。例如:
i telephoned him yesterday to ask what i should do next week. 我昨天給他打電話,問他我下周干什么。
比較:"what shall i do next week?" i asked. "我下周干什么?"我問道。
可以說,shall變成間接引語時,變成了should。
2) would也無詞義,是will的過去形式,與動詞原形構成過去將來時,用于第二、第三人稱。例如:
he said he would come. 他說他要來。
比較:"i will go," he said. 他說:"我要去那兒。"變成間接引語,就成了he said he would come。原來的will變成would,go變成了come.。
6. 短語動詞
動詞加小品構成的起動詞作用的短語叫短語動詞。例如:
turn off the radio. 把收音機關上。(turn off是短語動詞)
短語動詞的構成基本有下列幾種:
1)動詞+副詞,如:black out;
2)動詞+介詞,如:look into;
3)動詞+副詞+介詞,如:look forward to。構成短語動詞的副詞和介詞都統稱為小品詞
