therefore有兩種用法,一在整句中,一在分句中.therefore是副詞,但有時(shí)具有連詞作用。
一、整句中時(shí)一般不放句末,句首后要有逗號(hào),句中1、按一般副詞使用2、做插入語(yǔ)

例句：

1、Therefore,we must learn English well.
2、They therefore can learn English well.
3、Many fast food restaurant ,therefore,have red furniture or walls.
二、用在分句中，即一個(gè)句子一部分表示原因一部分表示結(jié)果。
這時(shí)一般詞前要用分號(hào),其后用不用逗號(hào)無(wú)所謂。若第二個(gè)分句前是逗號(hào)或無(wú)符號(hào)，則要注意therefore是副詞，和so不一樣,要保持句子完整，應(yīng)用and therefore。
例句：

1、I had a headache;therefore I could not go to your party.
2、I was ill,and therefore could not come.
3、These birds are very beautiful and therefore liked by many people.
