關(guān)閉窗口 8. 正確理解和運(yùn)用過去完成時(shí)的關(guān)鍵是什么
He asked me to have a drink with him. I said that it was at least ten years since I ______ a good drink.
A. had enjoyed B. was enjoying C. enjoyed D. had been enjoying
此題應(yīng)選A。容易誤選C。本題主要考察過去完成時(shí)的基本用法(過去完成時(shí)是各類考試的�？伎键c(diǎn)), 此用法的關(guān)鍵是要正確理解“過去的過去”這五個(gè)字，也就是說：過去完成時(shí)是一個(gè)相對時(shí)態(tài), 它必須以一個(gè)過去時(shí)間作參照, 而這個(gè)過去完成時(shí)所表示的動(dòng)作要發(fā)生在這個(gè)過去時(shí)間的過去。做這類題時(shí), 考生一定要注意一定的上下文, 要注意尋找直接或間接的過去參照時(shí)間：
1. He was disappointed that most of the guests___ when he ____ at the party.
A. left; had arrived B. left; arrived
C. had left; had arrived D. had left; arrived
2. The students _____ busily when Miss Brown went to get a book she _____ in the office.
A. had written;left B. were writing;has left
C. had written;had left D. were writing;had left
3. Helen _____ her keys in the office so she had to wait until her husband _____ home.
A. has left;comes B. left; had come
C. had left;came D. had left; would come
答案：1. D 2. D 3. C
9. This is the first time后的從句通常用什么時(shí)態(tài)
—Do you know our town at all?
—No, this is the first time I ______ here.
A. was B. have been C. came D. am coming
此題應(yīng)選B。這與句中的this is the first time有關(guān)：一般說來, 在It [This] is the first time＋that-結(jié)構(gòu)中, that-從句通常用現(xiàn)在完成時(shí)(www.hz123456.com)：
It’s the first time (that) the boy has spoken toa foreigner. 這個(gè)男孩還是第一次同外國人說話。
It’s the first time that she’s seen an elephant. 這是她第一次見到大象。
有時(shí)以上結(jié)構(gòu)中的first也可換成second, third, fourth等；其中的time也可換成其它名詞：
It’s the first month that he has lived here. 這是他第一個(gè)月住在這里。
This is the second cigarette that he has smokedtoday. 這是他今天抽的第二支煙。
若It was the first time that-結(jié)構(gòu)中, that-從句通常用過去完成時(shí), 有時(shí)也用一般過去時(shí), 有時(shí)若有包括現(xiàn)在在內(nèi)的時(shí)間狀語, 偶爾還可用現(xiàn)在完成時(shí)：
I was lucky because that was the second time I(had) visited
It was the first time this year that he hadn’t[hasn’t] worked on a Saturday. 這是今年來他第一次在星期六不上班。
