[四六级写作]怎样写好大学英语四级作文之文章过渡
众所周知，要写出清晰流畅的文章，需要把段落中各部分巧妙地连接在一起。这样可使文章自然而别致，并能层层展开主题句，完整地表达中心思想。
起连贯作用的过渡词语可以用来连接段落中的各个句子，也可以用来连接文章中的各个段落。下面是在段落中连接句子的例子（段中黑体字为过渡词）
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.
这一段中出现的过渡手法有两种：一种是过渡词或词组，如however, in this case, of course； 另一种是起过渡作用的代词，如this, one.
段与段之间也可以用过渡词连接，比如but可以连接两个为转折关系的段落．
