and和but作为连词的用法区别
英语单词and, but和however在用法上区别
(however [hau'evə] adv. 无论如何;不管怎样
conj. 然而;可是)
and,but 和 however 三个词都在句中起连接作用.现就它们的用法浅析如下:
一、and 作并列连词用.
1. 用来连接两个相同的句子成分.这两个句子成分可以是单词、短语或分句. and
连接两个分句时,分句本身都有自己的主语.如果第二个分句的主语与第一个分句的主语相同,则第二个分句中的主语可以省略.例如:
(1) When and where were you born? 你出生在何时何地?
(2) John and Tom are our good friends. 约翰和汤姆都是我们的好朋友.
(3) You are so big and the jar is so small that it could hardly hold one of
your feet.
你的个子这么大,坛子这么小,甚至连人的一只脚也容纳不下.
(4) She looked at Mr Hare and went on. 她看了看野兔先生,然后继续向前走.
2. 用 and 连接两个相同的词,意在强调或表示动作多次反复.例如:
(5) They talked and talked until late at night. 他们谈啊,谈啊,一直谈到深夜.
(6) There are books and books on the shelf. 书架上除了书还是书.
3. 当 and 用来连接两个动词时, and 后面的动词在意义上表示目的.在美国口语中, go (or come) and see 中的 and
一般都被省略.例如:
(7) Go and (= to) tell him the news. 你去把这个消息告诉他.
(8) Try and (= to ) get the work done today. 要设法在今天干完这项工作.
(9) I'll write and thank him. 我将写信感谢他.
(10) You'd better go (and) see a doctor. 你最好去看看医生.
二 . but 作为并列连词,在意义上起转折作用. but 前后的两个句子或短语在意义上形成鲜明对照. but 用来连接两个分句或两个较长的短语时,
but 前面一般要加逗号.例如:
(11) He is old but strong. 他年纪虽大却很强壮.
(12) Learning the guitar isn't difficult, but you will have to
practise.
学弹吉他并不难,但是你得练习.
(13) He tried, but could not do it. 他试过,但是干不了.
三 . however 意为“可是,然而,尽管”,较 but
的意味弱,通常用作连接性状语.其位置可以在句首,句末或插入句中.当其被用来对照两个分句时,中间需要有一个逗号;当它被用作句子的插入语时,则前后应各有一个逗号.例如:
(14) However, we need not do that now. 可是,我们现在不需要做那个.
(15) He said it was so; he was mistaken, however. 他说是那样的,然而他却弄错了.
(16) His friends, however, had other ideas. 然而他的朋友们却另有见解.
注: however 也可用作连接副词,意为“不论怎样”,用来引导让步状证从句.例如:
However we may do it, it will be a difficult job. 无论雪下得多大,我们都必须回去.
练习:用 but, and 和 however 填空:
1. I'd like to go with you, ________, my hands are full.
2. I'm sorry, ________ I won't be able to come tonight.
3. We must finish the job in time ________ hard it is.
4. They will supply food ________ drink on Saturday.
5. It looked like rain. ________, it is clear now.
6. Building has started ______ the project will be finished by 2000.
Key: 1. however 2. but 3. however 4. and 5. However 6. and
什么时候用and和but
首先你必须知道它们都是连词,在连接桔子或者修饰语时用,但是and 表示顺承关系,也就是表达意思相近的,对说过的句子进行解释,but则是表示转折,前后意思不是一样的时候用.通俗来说and 通常表肯定了,but 则是否定了
什么时候用but什么时候用and
表示并列或递进关系的时候用and,表示转折(通常翻译成“但是”)的时候用but。
希望可以帮到你。
and和but表示转折,有什么不同
and 多用于承接或者并列 基本上并没有真正意义上的转折 不过个别情况下视上下文而定可能会有转折的意味;而but是绝对意义上的转折,有but来分开的上下句,其意义一定是相反的或者语境是对立的。
eg: i can't wait to take a walk in the park because it is such a pretty park; and my neighbours are so bloody noisy, too! 我等不及要去公园散散步了--因为那座公园超漂亮的,而且我的邻居吵死人了!(所以我才想去散步)
'and'在这里就有一点转折的意思,因为前后两个原因毫无关联,但更多的意味是并列。
i would love to take a walk in the park but i hate walking pass my neighbour's scary bull dog. 我很愿意去公园散散步但是我讨厌经过我邻居的那只牛头犬。(所以我不会去散步的)这里'but'的转折意味是不是挺明显?
