[分析] “一般表达”句子之间的关系松散，转换为it作形式主语或感叹句后句子读起来很流畅。
二、转换句型
写作中常用于转换的三个重点句型：
1．there be句型
there be句型也是简单句中的一种常用句型，在作文中经常使用。在there be句型中，有时there be还可以换用there seems/seemed to be(似乎有)，there happened to be(碰巧有)，there may/might be(也许有)，there must be(肯定有)，there can't be(不可能有)，there ought to/should be(应该有)等。
我家有五口人。
There are five people in my family.
操场上碰巧有很多人。
There happened to be a lot of people on the playground.
2．感叹句
感叹句是作文中很有用的一种句型，常见的感叹句有两种：
[句型1] What＋(冠词)＋形容词＋名词＋主谓结构＋感叹号
[句型2] How＋形容词或副词＋主谓结构＋感叹号
What an interesting film (it is)!
＝How interesting a film (it is)!
3．强调句型
强调句型也是作文中常用的一种句型，强调句型的结构是：
It is/was＋被强调部分＋that/who＋原句其他部分。
I met my friend in the street yesterday.
