Step4、语法及要句：
Step5 现在完成时态
⑴由have/ has ＋ 过去分词
⑵表示过去发生或已经完成的某一动作对现在造成的影响或结果
常与already, just , yet , ever, never 连用

I have already finished it . 我已经完成了。
Have you ever been to China? 你曾经去过中国吗？
No, I have never been there. 没有，我从来也没有去过
• ⑶①表示过去已经开始，持续到现在的动作 或状态和表示过去某一时刻延续到现在（包括现在在内）的一段时间的状态连用如：（for + 时间段，since + 过去时间点，或过去某一动作，以及how long ）
• ②注：非延续性动词在现在完成时态中不能和for, since以及对它们提问的how long 引导的表示一段时间的状语的肯定句连用。应转为相应的延续性动词。
如：
buy---- have die---- be dead join ---- be in
borrow----- keep leave---- be away
I have bought a pen.------ I have had a pen for 2 weeks.
The dog has died.------- The dog has been dead since last week.

含义有所不同
must 一定肯定 (100%的可能性)
may, might, could有可能，也许 (20%－80%的可能性)
can't 不可能，不会 (可能性几乎为零)
can't 不可能，不会 (可能性几乎为零)
