prepare怎么用解释为老师备考.什么时候解释为学生准备考试.

给两个例句自己体会一下吧
做及物：e.g 1)The teacher prepares his students for the test.
T2)he students are busy preparing themselves for the test.
做不及物：e.g 3）The students are preparing for the test
4）The students are preparing to take the test.

3 )和4）是不同的，体会一下吧

看主语和语境。都是用prepare for the test。

比如说某人很努力地prepare考试，那十有八九是学生了。
