时态标志词主要有：for，since，so far，ever，never，just，yet，till / until，up to now，before，already，recently，in recent years，in the past few years
如：
I haven’t seen a student like that before. 我以前没有见过这样的学生。
They have just finished lunch. 他们刚吃完午饭。
The bus has already left. 公车已经开走了。
Have you heard from him yet? 你收到他的来信了吗？
Have you ever been to Los Angles? 你去过洛杉矶吗？
2.现在完成时与for/since等引导的持续性时间状语或so far等包括“现在时间”在内的时间状语连用。
3 by +时间点，表示“到…为止”，要和完成时态连用。当叙述过去的事情时，要用过去完成时。
不是吧，一般现在时还没有弄懂，直接问现在完成时了。就算是明白了，也应该是先弄现在进行时，一般将来时，一般过去式，过去进行时，最后学现在完成时。
present perfect 是现在完成时，表示过去的动作对现在有影响
经常与already,yet,still在一起
主语+has/have +过去分词
是has还是have，弄明白一般现在时，你会懂得。
