never又是频度副词又是频度状语,为什么?
1.作频度副词用法:放在be动词和助动词后面;行为动词前.
特殊用法:
1 sometimes可以放在句首、句中和句末
2 often 也可以放在句末
如:
Tom never went to see his wife..(在行为动词之前)
Tom has never been to China..(在第一个助动词后)
Tom is never late for school.(在系动词后)
属于这一类的副词还有often,sometimes,always,usually,already,nearly,almost等.
------------------------------------------------------------
2.作频度状语,一般都用于完成时.
1)i've never seen such a beautiful place.
2)this is the most beautiful place i've ever seen.

副词大多数时候都做状语
