眾所周知，要寫出清晰流暢的文章，需要把段落中各部分巧妙地連線在一起，怎樣寫好大學英語四級作文之文章過渡。這樣可使文章自然而別緻，並能層層展開主題句，完整地表達中心思想。
起連貫作用的過渡詞語可以用來連線段落中的各個句子，也可以用來連線文章中的各個段落。下面是在段落中連線句子的例子：
To many foreigners, the American word family is confusing. Foreigners often hear an American say "My family is coming to visit." In this sentence, family means grandparents and perhaps other relatives. However, at other times, the same American might say, "I'm going to stay home with my family this weekend." In this case, he is talking about his wife and children. This is a much narrower meaning than the first one. Using family in this way makes a foreigner wonder which term really describes an American family. The answer, of course, is that there are two meanings for the word family in the United States -- a narrow one and a broad one. And there is another term ---- immediate family ----- to describe something in between.
這一段中出現的過渡手法有兩種：一種是過渡詞或片語，如however, in this case, of course； 另一種是起過渡作用的代詞，如this, one.
段與段之間也可以用過渡詞連線，比如but可以連線兩個為轉折關係的段落．
2. 過渡詞語的分類 常用的.過渡詞根據意思和作用的不同，可以分為以下十一類：
1) 用以解釋的過渡詞，比如：now, in addition, for, in this case, furthermore, in fact
1. The problem, in this case, is hard to solve.
2. Furthermore, several people telephoned the same night.
2) 表示強調的過渡詞，如：certainly, indeed, above all, surely, most important
1. Indeed, a dessert is always enjoyable.
2. Above all, do not build an open fire in a forest.
3) 表示限制的過渡詞but, however, although, though, yet, except for
1. Yet there was still a chance that he would win.
