現(xiàn)在完成進(jìn)行時(shí)
現(xiàn)在完成進(jìn)行時(shí)表示在現(xiàn)在以前這段時(shí)間里一直在進(jìn)行的動(dòng)作，該動(dòng)作可能仍在進(jìn)行，也可能已經(jīng)停止了一會(huì)兒。
現(xiàn)在完成進(jìn)行時(shí)的謂語形式：have / has been +現(xiàn)在分詞。

How long has it been snowing?
I have been wanting to meet you for a long time.
Recently he has been doing his work quite regularly.
所有的動(dòng)詞都可以有現(xiàn)在完成進(jìn)行時(shí)，但是有些動(dòng)詞用于現(xiàn)在完成進(jìn)行時(shí)和現(xiàn)在完成時(shí)意義差別不大，有些則只能用于現(xiàn)在完成進(jìn)行時(shí)中。
