一个独立的句子反映一层相对独立的意思，由这些独立的句子组成的语篇虽然也能表达一定的含义，但是整个文章会显得枯燥乏味。学会使用连接词是增加句子连贯的最主要的一个手段。

★ 表示附加信息的连接词

这类连接词有：and, also, again, too, as well as, in addition(另外，此外), besides, moreover (而且，此外), not only ... but also ..., furthermore (而且，此外), then等。如：

★ 表示转折和让步意义的连接词

★ 表示因果和目的的连接词

常用的表示因果和目的的连接词有：for, because, consequently (所以，因此), therefore, for this purpose, as a result等。如：

After he had caught hold of the beltrope, we began to pull him up slowly, inch by inch, out of the hole. Finally, we could grab hold of his arms, and, with a sigh of relief (宽慰), we pulled him out onto the grassy bank. As he came up, no one dared to speak a word.

★ 表示空间的连接词
