有關therefore的兩種用法

時間: 焯杰674 分享

  therefore有兩種用法,一在整句中,一在分句中。下面學習啦小編為大家簡單介紹一下這兩種用法:

  一、整句中時一般不放句末,句首后要有逗號,在句中:1、按一般副詞使用2、做插入語。

  1、They therefore can learn English well.

  2、Many fast food restaurant ,therefore,have red furniture or walls.

  3、Therefore,we must learn English well.

  二、用在分句中,即一個句子一部分表示原因一部分表示結果.

  這時一般詞前要用分號,其后用不用逗號無所謂.若第二個分句前是逗號或無符號,則要注意therefore是副詞,和so不一樣,要保持句子完整,應用and therefore。

  1、I was ill,and therefore could not come.

  2、These birds are very beautiful and therefore liked by many people.

  3、I had a headache;therefore I could not go to your party.

  therefore雙語例句:

  1、We therefore don ’ t experience that “ fit in ” commandment the same way a Chinese person does.

  因此我們并沒有感受到中國人所感受到的“融入”緊迫性.

  2、permit me, therefore, to ascend the tree.

  因此,請您允許我站到樹上去。

  3、Soap should therefore be effective against all flu viruses.

  香皂因此對所有感冒病毒都是有效的。
