C

用于现在完成时的句型
1)It is the first / second time…. that…结构中的从句部分,用现在完成时。   It is the first time that I have visited the city.   It was the third time that the boy had been late.
注意比较 It’s time that … 结构:
It is high time that we went to school.
2)This is the… that…结构,that 从句要用现在完成时.   This is the best film that I’ve (ever) seen.    这是我看过的最好的电影。   This is the first time (that) I’ve heard him sing. 
这是我第一次听他唱歌。
典型例题 (1) --- 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
(2) --- Have you ____ been to our town before   --- No, it’s the first time I ___ here. A. even, come  B. even, have come  
C. ever, come  D. ever, have come     注意:非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。 (错)I have received his letter for a month. (对)I haven't received his letter for almost a month.
B
D
2、过去时
高考题点击:
1. --- Nancy is not coming tonight.
--- But she _____! A. promises B. promised C. will promise D. had promised
2. My uncle _____ until he was forty-five.
married B. didn’t marry
C. was not marrying D. would marry
说明:Nancy 答应要来这个动作应该发生在过去,是过去作出的承诺。
说明:until 用在肯定句中时,主句的动词必须是延续性动词,表示该动作一直持续到 until 后的时间为止;短暂性动词只能用在否定句中,表示直到此时该动作才开始。本题中 marry 是短暂性动词,所以只能用在否定句中。
B
B
3. --- You haven’t said a word about my new coat, Brenda. Do
you like it
--- I’m sorry I _______ anything about it sooner. I certainly
think it’s pretty on you.
A. wasn’t saying B. don’t say C. won’t say D. didn’t say
说明:本题的干扰源来自上下文中的时态,上文用的是现在完成时,下文用的是一般现在时,所以有些人就误以为此处该用现在时态了。但根据说话人的意思不难发现,没有说出自己的评价是在这段对话以前的事了,所以要用一般过去时。
D
4. As she ____ the newspaper, Granny ____ asleep.
A. read … was falling B. was reading … fell
C. was reading … was falling D. read … fell
5. The manager had fallen asleep where he ______, without
undressing.
A. was laying B. was lying C. had laid D. had lied
说明:一般来说在复合句中的两个动作,延续性的动作大都用进行时,短暂性的动词用一般时,表示在某个动作进行的过程当中另一个动作发生了。
说明:该题的意思为“经理躺在那儿睡着了,衣服也没脱”。“躺”是一个不及物动词,其过去式和过去分词为“lay; lain”。lay 是及物动词,过去式和过去分词为 laid;lied 是“说谎”的过去式和过去分词。

— Oh! I thought they ______ without me.
A.went B.are going C.have gone D.had gone
说明:哭得伤心发生在过去,而丢玩具熊发生在哭之前。两个发生在过去的动作,之前发生的用过去完成时,之后发生的用一般过去时。
说明:“他没叫我就走了”这个动作明显发生在“我认为”之前。所以必须用过去完成时。
B
D
3、将来时
1. If a man _____ succeed, he must work as hard as he can.
A. will B. is to C. is going to D. should
2. --- You’ve left the light on.
--- Oh, so I have. _____ and turn it off. A. I’ll go B. I’ve gone C. I go D. I’m going
说明:此句的意思为“如果一个人想要成功,就必须尽力而为”。If 引导的是条件状语从句,不能用将来时。而 be to 结构虽然表示将来的动作,但它不属于将来时。
说明:本句的重点是“并行结构”,关键是看后面的 turn,所以B、C、D、都不符合。
B
A
3. By the time Jane gets home, her aunt _______for London to
attend a meeting.
A. will leave B. leaves C. will have left D. left
4. We were all surprised when he made it clear that he _____
office soon.
A. leaves B. would leave C. left D. had left
说明:that 引导的宾语从句中的动作“离职”应该发生在“were surprised” 之后,故需用过去将来时。
C
B
说明:by the time 表示“到……为止”“在……之前”,如果主句的动作发生在过去,一般需要用过去完成时;如果是将来,就需用将来完成时。
4、状语从句中的时态问题
1. --- Can I join the club, Dad
--- You can when you _____ a bit older. A. get B. will get C. are getting D. will have got
2. In such dry weather, the flowers will have to be watered if
they _____.
have survived B. are to survive
C. would survive D. will survive
说明:时间状语从句中没有将来时,需用一般现在时替代一般将来时。
说明:条件状语从句中不用将来时,但 be to 结构不属于将来时态形式。
A
B
3. He will have learned English for eight years by the time he
_____ from the university next year.
A. will graduate B. will have graduated
C. graduates D. is to graduate
4. It ____ long before we ____ the result of the experiment.
A. will not be, will know B. is, will know
C. will not be, know D. is, know
说明:by the time 引导的是时间状语从句,故不能使用将来时。D选项虽可考虑,但 be to 结构大多用来表示“义务、决定、职责、约定”等,与句意不合。
说明:before 引导的是时间状语从句,无将来时,而主句应该用将来时。
