重点诠释
由于汉语中没有冠词的概念，因此英语中冠词的使用成为学英语者容易出错的地方。

1. the用于知道的人或物之前
Please open the window.
请开窗。
Where is the teacher?
老师在那儿？

2.表示语言的名词前一般不用冠词，但后面如果出现language一词，前面需加定冠词the。
English=the English language French=the French language

e.g. He can speak English= He can speak the English language.

It is surprising that the German can not speak the German language.
这个德国人居然不会说德语,这是令人惊讶的。
