Get the Ss to learn and analyze the knowledge and use of the Present Perfect Continuous Tense in groups .

【用法归纳】现在完成进行时的结构是：have/has+been+doing；它常与recently, for many years/weeks, all winter/all this time/all the time等表示动作持续的时间状语连用，表示动作从过去开始，暗示还在持续或者将要持续。现在完成进行时似乎并不难理解。然而，如果把它与其它时态放在一起让考生鉴别，那就并非那么简单了。

【考题解读】

一般地，命题者都是根据现在完成进行时的定义，给出明显的提示词语，判断正确答案很容易。

例1. I have to see the doctor because I

a lot lately. （2010陕西）

A. have been coughing

B. had coughed C. coughed

D. cough 【解析】考查动词时态。由时间状语lately可知此处表示现阶段一直在进行的动作或存在的状态，且强调其持续性，用现在完成进行时，故选A。

例2.Joseph ______to evening classes since last month, but he still can’t say “What’s your name?”

in Russian.（2010辽宁）

A．has been going

B．went

C．goes

D．has gone 【解析】考查时态。句中since last month，表示“自从上个月起”根据but后的句意，说明动作从过去发生到现在一直在进行着，所以要用现在完成进行时态。故选A。

例3. ----We’ve spent too much money recently. 2010安徽

----well, it isn’t surprising. Our friend and relatives _______around all the time

A. are coming

B. had come

C. were coming D. have been coming 【解析】本题考查时态用法。依据题中给出的recently和

all the time两个时间状语可知本题选D。

但是，如果题干没有给出明确的表示动作持续的时间状语，那将怎么鉴别呢？

例1. —why, Jack, you look so tired! （2010江苏）

—Well, I _____the house and I must finish the work tomorrow.

A. was painting

B. will be painting

C. have painted

D. have been painting 【解析】因为you look so tired! I must finish the work tomorrow.两句说明油漆房子一

直进行到现在，而且到明天才会完成。所以用现在完成进行时。选D。

例2.Mr. White works with an import and export company, but he ____ for this industrial fair, since he is on leave. （09江苏省南通市高三一模）

A. has worked

B. works

C. has been working

D. is working 【解析】选D。因为since he is on leave。

例3.My cousin went to Canada two years ago. He

there for a few months and then went to America. (06江西) A. worked

B. would workC. would be working D. has been working 【解析】答案

选A。考查一般过去时的基本用法。句中并列连词and连接两个发生在过去的顺承的动作，时态应该一致。

例4.They became partners at work that day. Until then, they ______ to each other for

nearly three years.

A. didn't speak

B. hadn't spoken C. haven' t spoken D. haven' t been speaking 【解析】答案

选B。因为became的动作发生在hadn't spoken之后。

例5.Although he _________ in the countryside for more than 10 years, he could still communicate with the foreigners fluently when he returned to the city.

A. worked B. had worked C. has worked

D. has been working
