介词是一种用来表示词与词, 词与句之间的关系的词。在句中不能单独作句字成分。介词后面一般有名词代词或相当于名词的其他词类，短语或从句作它的宾语。介词和它的宾语构成介词词组，在句中作主语, 状语，表语，补语或介词宾语。例如:
Most of the students went to the classroom.
大部分学生去了教室。
We play basketball on the sports ground.
我们在操场上打篮球。
介词常与动词,形容词,名词一起构成固定搭配。
belong to 属于 rely on 依靠
talk to 同...谈话 be afraid of 害怕
be strict with对...严格
介词一般放在名词之前。但它后面的介词宾语是疑问代词,疑问副词或者关系代词时，这些词提到了前面而只剩下介词在后了。

你是哪儿人?
Who are you talking to?
你在跟谁谈话呢?
What do you study for?
你为了什么而学习?
