      therefore的用法以及與because、for的區(qū)別(2)

      時(shí)間: 若木631 分享
      Get up early tomorrow,or you will miss the early train.你明天要早點(diǎn)起身,要不然就趕不上早班火車(chē)了。

        Don't jump the queue,or other peopoe will not be pleased.別插隊(duì),否則別人會(huì)不高興的。

        可以把這類句型中的祈使句換為一個(gè)條件句(注意改寫(xiě)時(shí)應(yīng)去掉連詞or)。

        例如: Hurry up,or you will be late for the meeting.→If you don't hurry up,you will be late for the meeting.

        otherwise 用作連詞,意思為“否則;要不然”,相當(dāng)于 or,or else 或 if not .

        例如: We’ll go early,otherwise we may not get a seat. 我們得早點(diǎn)去,要不然就沒(méi)有座位了。

        Seize the chance,otherwise you will regret it. 抓住機(jī)會(huì),要不然你會(huì)后悔的。

        I was ill that day,otherwise I would have taken part in the sports meet. 那天我病了,否則我會(huì)去參加運(yùn)動(dòng)會(huì)的。

        We didn’t know you were in trouble at that time,otherwise we would have given you a hand. 我們當(dāng)時(shí)不知道你遇到了困難,要不然我們會(huì)幫助你的

        because、for、therefore作“因?yàn)?rdquo;講的區(qū)別

        for ,because,as,since這四個(gè)詞作為連詞,都有"因?yàn)?quot;的意思,但它們?cè)谟梅ㄉ嫌袇^(qū)別:

        because 是從屬連詞,接表示直接原因的從句,一般放在主句的后面,也可放在主句前面,它表示的語(yǔ)氣最強(qiáng),在回答why的問(wèn)句時(shí),必須用because。

        例如:The swimming pool won't be open today because they're making repairs.

        游泳池今天不開(kāi)放,因?yàn)樗麄冊(cè)谛蘩怼?/p>

        Why did you move to France?

        你們?yōu)槭裁窗岬椒▏?guó)?

        Because my father found work in Paris.

        因?yàn)槲腋赣H在巴黎找到了工作。

        注意:在英語(yǔ)中用了because后,不可再用so。

        as 是從屬連詞,說(shuō)明一般的因果關(guān)系,語(yǔ)氣比because弱,說(shuō)明比較明顯的原因,它引導(dǎo)的從句通常放在句首,有時(shí)也可放在句末。

        例如:As it is raining, you\'d better take a taxi.

        天下雨了,你最好乘出租車(chē)。

        since 意為"既然",表示對(duì)方已知的無(wú)需加以說(shuō)明的原因或事實(shí),語(yǔ)氣比because弱,但是比as 強(qiáng)。

        例如:Since we have no money, we can't buy that vase.

        既然我們沒(méi)錢(qián),我們就不能買(mǎi)那花瓶。

        Since everybody is here, let's begin our party.

        既然大家都到了,那就開(kāi)始我們的聚會(huì)吧!

        for 是并列連詞,用來(lái)附帶解釋說(shuō)明前一分句的原因或理由,for引導(dǎo)的并列句,一般放在所要說(shuō)明的句子的后面。

        例如:I went to see him, for I had something to tell him.

        我去見(jiàn)他,因?yàn)槲矣惺乱嬖V他。

        只有therefore是表示結(jié)果的意思而不是原因.
