写作的最基本要求不是文章中有多么华丽的辞藻和句子，而是句子的准确性。

英汉名词有许多共同点，但是也有不少不同点。

英语名词有可数与不可数之分，汉语里没有，且一般情况下，名词都可受到数量词的限制。

因此，英语写作中，一旦涉及到advice, news, progress, weather, information等少数常用不可数名词时，学生往往会犯错误。

不过，在使用英语不可数名词时，又会出现两种情况：

↓↓↓

一种是绝不可以用a/an或数词来直接修饰，如上述提及的几个名词；

另一种情况是，少数不可数名词在被形容词等修饰后，可用a/an等来修饰。如time（时间），rain（雨）。所以我们可以说：We had a wonderful time yesterday.

 举个例子：

a. The air is the most important thing for our existence.

b. The driver brought the car to stop. In this way, he avoided an accident.

c. When sun was setting, he still did not catch any fish.
