2016-08-24 17:36:31来源:网络

  注意

  在《both…and…》句型中,and连接的词或词组要对等。

  2.《both…and》的否定句表示部分否定。

  He can't play both the violin and the piano.

  他会拉小提琴或者会弹钢琴。(不全会)

  Both Li Ming and Li Li are not good students.

  明和李莉不都是好学生。(其中一个是好学生)

  6 either…or,neither…nor

  I want to visit either Tianjing or Shanghai.

  我想参观天津或者上海。

  I like neither English nor Chinese.

  中文和英文我全不喜欢。

  1.either…or:或……或……;不是……就是……

  a.《either…or…》构成的词组作为主语时,谓语动词随其邻近的词,即or后面的词而定。

  Either you or he is right.

  不是你,就是他是对的。

  b.此句型的否定句是全否定。

  Either you or he isn't right.你和他都不对。

  I don't want to visit either Tianjing or

  Shanghai.天津和上海我都不想参观。

  2.neither…nor:既不……也不……

  a.当此词组担任主语时,谓语动词的用法和either…or的用法一样,由nor后面的词而定。

  Neither you nor I am right.你和我都不对。

  b.此句型本身是全否定,因此不能再用否定式,即不能再加not。

  (×)Neither You nor I am not right.

  比较

  both …and ,either…or ,neither …nor 这三个句型的相互关系如下:

  1.肯定句:I like both A and B.我喜欢A和B。

  I like both coffee and tea.

  我喜欢咖啡和茶。(茶和咖啡我都喜欢)

  2.否定句:I don't like both A and B. =I like either A or B.

  我不喜欢A 或B。

  I like either coffee or tea .

  咖啡和茶,我喜欢一样儿。

  =I don't like both coffee and tea .

  3.I don't like either A or B .=I like neither A nor B.

  A和B 我都不喜欢。

  咖啡和茶,我都不喜欢。

  I like neither coffee nor tea .

  I don't like either coffee or tea .

  7 not only… but also:不但……而且

  (1)Not only you but also your father is coming.

  不但你,而且你父亲也要来。

  (2)Jane is not only beautiful but also kind.

  珍妮不但漂亮,而且人非常好。

  1.基本用法:《not only…but also》担任主语时,此句型的谓语动词随 but also后面的部分而定,参见上文例(1)。

  另外not only…but also连接对等的词或词组;例(1)you(你)和 your father(你父亲)都是人。例(2)beautiful(美的)和kind(亲切、慈祥)都是形容词。

  2.该句型可以和“as well as”互换,但注意汉语翻译。

  Your father as well as you is coming.

  不但你,而且你父亲也要来。

  注意

  as well as的句子谓语动词随它前面的词“Your father”而定,所以用is coming.

  Jane is kind as well as beautiful.

  珍妮不但漂亮,而且为人很好。

  2 从属连词

  常见的从属连词有:

  (1)引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等。(2)引导条件状语从句的if, unless等。

  (3)引导原因状语从句的because, as, since等。

  (4)引导目的状语从句的so that, in order that等。

  (5)引导让步状语从句的though, although, even if等。

  (6)引导结果状语从句的so that, so…that, such…that等。

  (7)引导比较状语从句的than, as…as等。

  (8)引导名词从句的that, if , whether等。

  1 that

  I think(that) he likes football.

  我想他喜欢足球。

  that引导名词性从句(主语从句、表语从句、宾语从句和同位语从句)和定语从句,本书只介绍宾语从句。

  1.that在宾语从句、间接引语中可以省略,主句与从句时态一致。

  I think(that) he is tired.我想他累了。

  I thought(that) he was tired.

  注意

  要特别注意主句与从句时态的呼应。如果主句是过去时,从句一律改为过去的时态,详见第二十章宾语从句。

  2.如果主句的动词是 think, believe…;如果主句的主语是第一人称,变为否定句时,要否定主句,译成中文时,则否定从句。

  I believe you will leave here.

  我相信,你会离开这儿的。

  I don't believe you will leave here.

  我相信,你不会离开这儿的。

  必背!

  I hope that~我希望~

  I think that~我认为~

  I say that~我说~

  I know that~我知道~

  I find that~我发现~

  be afraid that~恐怕~

  be sure that~确认~

  be glad(happy) that~很高兴~

  (以上的that都可以省略)

  2 when,while,till,until,since…

  When he arrives there he will call you.

  他到达那儿以后,他会给你打电话。

  when, while, till, until, since, after, before, as soon as等是连接时间状语从句的连词。在时间状语从句中要特别注意时态的搭配:当主句是将来时,从句要用一般现在时。

  注意

  while所引导的从句的谓语动词只能是延续性的,不能用点动词。(如begin,stop…)

  When I arrived there, it was raining.

  当我到那儿时,天正在下雨。

  I entered the room while(when) Li Ming was talking with her.

  我进屋时,李明正在和她谈话。

  We won't work until(till) our teacher teaches us how to do it.

  老师教给我们如何做这工作之后,我们才会开始做。

  He came to China after the war was over.

  比较

  连词连接从句不同,意思不同。

  He had been in China before the war was over.

  战争结束前,他已经在中国了。

  =The war was over before he came to China.

  =The war had been over before he came to China.

  战争结束后,他来到中国。

  I have learned more than two thousand English words since I began learning English two years ago.

  自从两年前我开始学习英语以来,我已经学习了两千多个英语单词了。

  注意

  since引导的是一个过去时的句子,说明自当时以来到现在(自从两年前以来),主句一般要用现在完成时。

  As soon as I get enough money,I'll buy it.

  我一得到足够的钱,就买它。

  3 because:因为,连接原因状语从句

  She didn't go there,because she was ill.

  因为她病了,所以她没去那儿。

  1.回答Why问句时,只能用because,不能用for或 as.

  你为什么迟到?

  Because I met a traffic accident on my way here.

  因为在我来这儿的路上,遇到了车祸。

  2.汉语中,我们经常说因为……所以,但在英文中有了because,就不能再用so。

  (×)Because he was tired, so he couldn't walk there.

  因为他累了,所以他不能走到那儿了。

  4 if,though (although)

  If it doesn't rain,we'll go to the park.

  如果不下雨,我们就去公园。

  Though I was tired, I still worked hard.

  虽然我很累,可是我仍然努力地工作。

  1.if:如果(引导条件从句)

  You can pass the exam if you study hard.

  如果你努力学习,你会及格的。

  2.though,although:虽然(引导让步状语从句)和原因状语从句一样,如果用了though,although (虽然)就不能再用but(但是)。

  Although(Though) I live near the sea, I'm not a good swimmer.

  =I live near the sea,but I'm not a good swimmer.

  虽然我住在海边,可是我游泳并不好。

  注意

  注意时态一致,和时间状语从句一样。主句是将来时之时,从句要用一般现在时。

  5 so…that:太……以致……

  他太老了,不能工作。
