Make sentences about the inventions、

1.表一个过去动作对现在的影响也就是影响性， 它与过去一般时容易混淆。因为都表过去动作， 区别是，一般过去时常有具体的过去性时间点 作时间状语，强调在什么点上发生了---动作：
e.g. 1).I had my lunch at 12:30.
2).He came here half an hour ago .
2).You have just told me about it. 3).We haven't heard of him before
2021/3/12
5
2.现在完成时还表持续性，这种情况下要用延续 性动词表动作从过去的一个点一直持续到现在 （可能还仍在持续着）,常跟由since引导过去点 状时间状语,表动作起点，还可跟由for引导的线状 时间状语,表时间线段）
2021/3/12
4
现在完成时表示的过去动作主要强调它对现 在的影响，而不是在什么点上发生，因此不 跟具体时间点，却常有already(早已） /yet(还没）just, before 等时间比较含糊的时 间状语从句。
E.g. 1).She has already finished her competition./I haven't yet.
3.He has been a member of the Party for 4
years.(这里be a member of 不能用非延续动词短
语j2o02i1n/3/1t2he party)
6
Since 用来说明动作起始时间，for用来 说明动作延续时间长度。
I have lived here for more than twenty years.
现在完成时
现在完成时（Present perfect）表示过去发生 并且已经完成的动作对现在造成影响或后果， 过去某一时间开始并一直持续到现在的动作或 状态。
