现在完成时（三）
1.现在完成时的“未完成用法”。
现在完成时表示动作或状态从过去某时开始，一直延续至今，还可能继续下去。这种用法称为“未完成用法”。此时常与 for 或 since 引导的时间状语(从句)连用。
“未完成”的句式：
（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
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。
2.延续性动词与非延续性动词
(1)延续性动词表示经验、经历；
非延续性动词表示行为的结果。
非延续动词不能与表示一段时间的状语连用。有些非延续性动词可以用延续性动词替换并用在现在完成时中。
非延续性动词（短语）与延续性动词（短语）
的转换：
①直接转换成延续性动词
buy → have borrow → keep put on →wear

例：She caught a cold three days ago.
=She has had a cold for three days.
②转换成“be＋形容词/副词/介词/名词”等

die → be dead leave → be away
close → be closed fall asleep → be asleep
fall ill → be ill become → be
