你好。不一定，尤其是否定句，如：I saw her three weeks ago.这里saw就是延续动词。如果用现在完成时改写的话，see仍然是延续动词，但后面可以加for -- - - / since- - --. 看：
1 I haven't seen her for two weeks
2 I haven't seen her since two weeks ago.
3 I haven't seen her since the beginning of this month.
------------------- 明白了吗？ a good day to you. -----------------
1 I haven't seen her for two weeks
