Summary
用法：
我们用现在完成时表示从过去持续到现在的动作或状态，或已完成但对现在有一定影响的动作。现在完成时也可和频度副词一起表示某个动作到现在发生的次数。
现在完成时常和 already、ever、just、never、recently、yet 等副词以及 since、for 引导的时间状语连用。
e.g. He has not returned the book to me yet.
他还没有把那本书还给我。
He has never visited the Great Wall. 他从没去过长城。
Suzhou classical gardens have been famous for a long time.
苏州园林已闻名许久。
注意：already 常用于肯定句，意为“已经”，而 yet 常用于否定句和疑问句，意为“还”。
