老師好，

       試比較下列幾句話：

       1. It has been raining all the day. I'm tired of it.

       2. Have you been waiting long?

       3. I have been waking up in the night a lot.  

       1句，可以理解，確實(shí)一整天中，每時(shí)都在下雨

       2,3句理解不了，2句：確實(shí)每時(shí)都在wait，但不是每時(shí)都是wait long啊，long是最后的結(jié)果；

                                  3句： 醒來的動(dòng)作反復(fù)多次，但這是最后的結(jié)果，醒來是一次一次地，不是每次都是 a lot

       還請(qǐng)老師解說

It has been raining all the day. I'm tired of it.

Have you been waiting long?

I have been waking up in the night a lot.  

在句中，謂語(yǔ)動(dòng)詞是時(shí)態(tài)和語(yǔ)態(tài)的體現(xiàn)，是一個(gè)整體，不要把助動(dòng)詞（包含情態(tài)動(dòng)詞）和非謂語(yǔ)動(dòng)詞割裂開來。三個(gè)時(shí)間狀語(yǔ)，都是修護(hù)整個(gè)黑體部分。
