mainly在句子中的位置（mainly和largely的用法区别口诀）

可以放在句中，例如：

1.This expression is used mainly in speech, not in writing.这种表达主要用于口语，而不是书面语。

2.The fashion at the time was for teaching mainly the written language.那时教学时兴的主要是书面语。

3.The people in the hotel were mainly foreign tourists.酒店里住的大多是外国游客。

mainly作为副词，用来修饰句子中的谓语部分或全句，因此即可以放句首，也可以放be动词后面或谓语动词前面。
