. 瞬间动词转换成持续性动词
瞬间动词用于完成时态不能与一段时间状语连用，须转换成持续性动词。
1.用相应的延续性动词替换的有：
buy---have borrow---keep put on----wear
catch/get a cold---have a cold
come/go/become---be 等。
eg. 1.We have had the TV set for 3years.
2.I have kept the book for 2 weeks.
2.转换成be+名词的有：
join the army----be a soldier
join the Party----be a Party member
go to school----be a student 等。
eg. 1.He has been a soldier for 5 years.
2She has been a student for 2 months.
3.转换成be+adj/adv.
die—be dead finish—be over begin---be on
leave---be away move----be out of .
. put on---be on open---be open close---be closed
fall asleep------be asleep 等。
eg. He has been dead for 5 years.
4. 转换成be+介词短语
go to school----be in school
join the army---be in the army 等。
eg. 1.She has been in the army for 2 years.
2.He has been in school for 9 years.
5.通过去掉短语中的结束性动词
get to know---know
begin to study---study
come to work----work
eg. 1.We have known each other for 10 years.
2.He has study Chinese for 2 years.
*瞬间动词完成时的否定式已成为一种可延性状态，因此可以和表示一段的时间状语连用。
eg. 1.I haven’t heard from her for 6 months.
2.I haven’t bought anything for 2 months.
