前置词支配宾格(的名词或代词)。

A preponderate governs (a noun or pronoun in) the objective case.

那前置词的用法和定冠词是一样的。

And the use of these is just the same as the definite articles.

大家应该也理解了，前置词就是介词加上定冠词。

To form these preposition, you can just put the preposition with the definite articles.

苗语中存在差比句补语，造成这种区别的原因是苗语的SVO型和前置词型特征比汉语典型。

There is comparative complement in Miao language because in Miao language, the structure of SVO and preposition are much more typical than that in Chinese.
