在考慮英語句式變化時，我們可以從以下幾個方面入手
1. 既可以用主動式也可以用被動式

---Today machines are widely used not only inindustry but in other sectors of national economy as well.
2. 既可以用肯定式也可以用否定式

3. 某些修飾成分既可以用在句子前面也可以用在后面，還可以用在中間。（插入語）
With a car,people can get around freely.

Infact, speaking is one of the most important means of communication。

4. 即可以是正常語序也可以是倒裝語序

Among the products on display was a newtype of TV sets.
We did not realize the problem untilyesterday.

5. 既可以用簡單句也可以用并列句或主從復(fù)合句

6．應(yīng)用修辭，增強說服力。
