Grammar Focus
1.for和since的区别
（1）现在完成时+ for +一段时间
例：我好久没有见到她了。
I haven’t seen her for a long time.
（2）现在完成时+ since +表示过去的时间点
例：自1984年以来，史密斯先生就在这里工作。Mr. Smith has worked here since 1984.
（3）现在完成时+since+从句(句子要用一般过去时态）
例：自上大学以来他学了大约5000个英语单词。
He has learned about 5000 English words since he went to college.
谓语动词用延续性动词，可以用how long提问。
since＋一段时间＋ago＝for＋时间段;
since two weeks ago=for two weeks;
I have kept the library book for a week.
= I have kept the library book since a week ago.
在现在完成时态中，for与since引导的时间状语可以相互转换。
1. I have owned the toy bear ____ more than
six years.
2. He has worked as a policeman ____ ten
years.
3. They have worked here ______ June.
4. She has studied English ______ she was
five.
Fill for or since in the blanks
for
for

2.非延续性动词
表示短暂意义的动词在完成时中不能和表示一段时间的状语连用，因为它们表示的动作不能持续。
be/get(系动词)——be
