时态的判定
初中阶段需掌握六种基本时态。学生可根据以下5点来判断不同时态的选用。
(1)巧用提示辨时态
遇到时态题时,首先要寻找时间标志词,如果题干中有时间标志词,可以根据时间状语选择相应的时态。需要注意的是,个别时间状语可用于不同的时态中,考生需具体情况具体对待。
如:I a high school student this September.I can’t wait!
A. am B. was
C. have been D. will be
方法点拨 第1步:分析语境:今年九月我就会是一名高中生了。我等不及了! 第2步:分析选项,A项:一般现在时;B项:一般过去时;C项:现在完成时;D项:一般将来时。第3步:根据时间状语this September以及句子描述可知选D。
(2) 细心体会辨语境
在有些情况下,动词的时态是由上下文语境来决定的,这就要求我们既要理解上下文的语境,也要掌握各种时态的灵活运用。
如果一个英语句子中既没有出现时间状语,也没有可供判断时态的上下文,那么就应当把这个句子翻译成中文,利用我们的母语知识来判断这个句子该用何种时态。
如: —Where is Miss Li?—She ___ the laboratory.
A. is going to B. has gone to
C. went to D. goes to
方法点拨 第1步:分析语境“李老师在哪里?” “她去实验室了。”第2步:分析选项,A项:一般将来时;B项:现在完成时;C项:一般过去时;D项:一般现在时。第3步:结合语境可知这里指“李老师去图书馆的动作发生在过去,在双方说话时她还没回来”,应用现在完成时,故选B。
(3) 主从时态须呼应
主从复合句中谓语动词时态的一致主要有以下几种情况:
①“主将从现”原则。如果主句是一般将来时,从句是由 when, after, before, not...until, as soon as 等引导的时间状语从句以及由 if, unless 引导的条件状语从句时,谓语动词应用一般现在时表示将来时。
如:He is going to be a scientist when he ____up.
A. grows B. grew
C. will grow D. has grown
方法点拨 when引导的时间状语从句遵循“主将从现”原则,即主句用一般将来时,从句需用一般现在时。故选A。
②在主从复合句中,如果主句和从句的谓语动词表示的两个动作都发生在过去,而且有明显的先后顺序,那么,延续性动词用过去进行时,短暂性动词用一般过去时。通常在when和while引导的时间状语从句中出现。
如: The children ___ a picnic in the park when it suddenly began to rain.
A. have B. are having
C. had D. were having
方法点拨 找出题目中的关键词“when”。when引导的时间状语从句的时态为一般过去时,且“began”为短暂性动词,主句表示延续性的动作,谓语动词应用过去进行时。故选D。
③在含有“since从句”的主从复合句中,主句常用现在完成时,从句常用一般过去时。另外,在“It’s+一段时间+since+从句”句式中,since 后面的从句常用一般过去时。
如: —Long time no see!—Oh! It five years since we met last time.
A. was B. were
C. has been D. have been
方法点拨 句意为“好久不见!”“哦!自从我们上次见面以来已经五年了。”since是现在完成时态的标志词,因此主句应用现在完成时态。主语It是第三人称单数,谓语动词应用has。故选C。
④当主句谓语动词的时态为一般现在时、现在进行时、现在完成时等时态时,后面跟的宾语从句中的谓语动词的时态不受主句时态的限制,可根据具体情况,选用各种合适的时态。
如:I don’t know if he ___ to play basketball with us.
A. comes B. came
C. will come D. has come
方法点拨 句意为:我不知道他是否会来和我们一起打篮球。if作为“是否”讲,宾语从句中的谓语动词的时态不受主句时态的限制,因为事情还没有发生,应用一般将来时。故选C。
⑤“时态一致”原则。在含有宾语从句的主从复合句中,当主句的谓语动词为过去时态时,从句的谓语动词需用相应的某种过去时态。
如:I didn’t understand ___, so I raised my hand to ask.
A. what my teacher says B. what does my teacher say
C. what my teacher said D. what did my teacher say
方法点拨 第1步:分析选项可知本题考查宾语从句的语序及时态。宾语从句需用陈述句语序,排除B和D项。第2步:根据“时态一致”原则,即主句的谓语动词为过去时态,从句的谓语动词需用相应的某种过去时态。故选C。
(4)上下一致定时态
在这种情况下,动词的时态是由上下文已有的时态信息来确定,这就要求我们准确判断上下文所表达的时态信息,确定恰当的时态。
如: —I can’t find David. Where is he?—He for tomorrow’s competition at home.
A. prepares B. prepared
C. is preparing D. has prepared
方法点拨 第1步:分析语境:“我找不到大卫。他在哪儿?”“他正在家里为明天的比赛做准备。”第2步:问句为一般现在时,可知答语表示他此刻正在为明天的比赛做准备,应用现在进行时,故选C。
(5)瞻前顾后巧搭配
在英语中,不少句型与一些动词在时态的运用方面都存在着特定的对应关系。
①在“祈使句+and/or+陈述句”句型中,陈述句中用will表示一般将来时。
如:Hurry up, or you ____ the early bus.
A.miss B. missed C. will miss D. have missed
方法点拨 分析句子结构可知这是“祈使句+or +陈述句”句型,陈述句的谓语要用“will+动词原形”,故选C。
②在This/That/It is the first time that...
句型中用现在完成时。若is改为was,就用过去完成时,有时以上结构中的 first 也可换成 second, third, fourth 等,其中的time也可换成其他名词。
如:This is the first time that I ___ a baseball game.
A. am watching B. was watching
C. have watched D. will watch
方法点拨 分析句子结构可知此处考查This is the first time…句型,后面所加从句应用现在完成时。故选C。

2.I don’t want him to help me because he (prepare) for his exams.
【答案】is preparing
【详解】句意:我不想让他帮我,因为他正在准备考试。根据“I don’t want him to help me because he… for his exams.”可知,此处强调此时正在为考试做准备,用现在进行时强调现在正在发生的动作,主语he是第三人称,助动词用is,故填is preparing。

【详解】句意:——快点!马克和卡罗尔在公共汽车站等我们。——等一下!我来了。根据前文“Hurry up”表催促且后文“Just a minute! I’m coming.”可推测Mark和Carol应该是正在等,要用现在进行时谓语用“be doing”。又因为主语是“Mark and Carol”是复数要用“are”。故填are waiting。
5.— The alarm clock is broken and there’s a lot of traffic and the weather is......
— Oh, boy, you (make) up an excuse again, can you just admit (承认) your mistake?
【答案】are making
【详解】句意:——闹钟坏了,路上还塞车,还有天气…… ——哦,孩子,你又在编借口,你就不能承认你的错误吗?根据句意可知,此时前者正在编造借口,而打断了前者的话,故用现在进行时;“make”的现在分词是“making”。故填are making。

while和when都是表示同时,到底句子中是用when还是while主要看从句和主句中所使用的动词是短暂性动作(瞬时动词)还是延续性动作,进行时态一般是延续性的,过去式一般是短暂性动作。区别如下:
1、若主句表示的是一个短暂性的动作,而从句表示的是一个持续性动作时,两者都可用。如:
He fell asleep when [while] he was reading. 他看书时睡着了。
I met him when [while] I was taking a walk in the park. 我在公园散步时遇到了他。

1.We (climb) the hill when it began to rain yesterday.
【答案】were climbing
【详解】句意:昨天开始下雨时,我们正在爬山。根据“when it began to rain yesterday.”可知,此处表示过去某一时间正在做某事,时态为过去进行时,其构成为主语+was/were+doing,主语为We,复数,故此处用were,climb的现在分词为climbing。故填were climbing。
2.—Did you see Anne outside the door just now?
—Sure. She (ring) someone, so I nodded to her and went away.
【答案】was ringing
【详解】句意:——你刚才在门外看见安妮了吗? ——当然。她在给别人打电话,所以我向她点了点头就走开了。根据“so I nodded to her and went away.”可知,此处是指“我”向安妮点头时她正在打电话,应用过去进行时,其结构是was/were doing;主语She为第三人称单数,be动词用was;ring“打电话”,动词,其现在分词为ringing。故填was ringing。
3.When I arrived at the theatre, all the followers (wait) for the show to start.
【答案】were waiting
【详解】句意:当我到达剧院时,所有的粉丝都在等待演出开始。“arrived”是一般过去时,而“等待演出开始”这个动作在“到达剧院”这个时间点正在进行,所以要用过去进行时。主语“all the followers”是复数,所以be动词用were,wait的现在分词是waiting。故填were waiting。
4.Sorry, I didn’t hear your word. I (think) about which book to read next.
【答案】was thinking
【详解】句意:对不起,我没听到你的话。我在想接下来读哪本书。根据“Sorry, I didn’t hear your word.”可知,后一句思考这个动作是在过去某一时刻正在进行,用过去进行时态,结构为was/were+doing,主语是I,be动词用was,think的现在分词为thinking。故填was thinking。
5.The children (do) their homework when the power went out.
【答案】were doing
【详解】句意:停电时,孩子们正在做作业。结合“when the power went out.”可知,主句时态是过去进行时,其结构为was/were + doing,且主语“The children”为复数名词,所以be动词用were。故填were doing。
三.完成句子
1.当我进来时,他正在读书。
2.你写信的时候,我在看书
【答案】1.He was reading when I came in.
2.While you were writing letters,I was reading a book.
现在完成时
1.定义:现在完成时表示一个发生在过去的、对现在仍有影响的动作,或表示开始在过去,并且一直延续到现在,甚至还可能延续下去的动作。
2.构成:have (has)+done——动词变过去分词
基本句型: past now future
句型:
have done
has done
陈述句
I have seen that film before.
She has seen that film before.
否定句
I haven’t seen that film before
She hasn’t seen that film before.
疑问句
Have you (ever) seen that film before?
Yes, I have./No,I haven’t.
Has she (ever) seen that film before?
Yes, she has./No,she hasn’t.
3.时间标志:already, yet, just, once, twice,ever, never,three times, before等。
如:I have never seen such fine pictures before. (我以前从来没有看过这么好的画)
He has just gone to England.(他刚去英国)
(1)for和since的用法及区别。for与一段时间连用,since与时间点连用。注意:since 后接过去时的时间状语或过去时的句子。 2010 2020
如:I have lived here for 10 years.(我已经住在这10年了)
I have lived here since 2010. (since 10 years ago) (从2010年开始,我就已经住在这了)

be on
come
be here
go
be there
finish
be over
die
be dead

have a cold
put on
wear
wake up
be awake
fall asleep
be asleep
lose
not have
join
be in
leave
be away
arrive/reach

5.提示:have been to, have gone to和have been in的区别
have been to 曾经去过某地(现在已经回来了),常与just, ever, never等副词连用。
have gone to 去了某地(现在还没有回来),表示说话时某人已不在现场,可能在去的途中,也可能已经到达目的地。
have been in 已经在某地,表示状态,后面常接表示“时间段”的状语。

一.单项选择
1.—Is Ms. Green in the office now?
—No. _______ the library.
A.He has been to B.He has gone to C.She has been to D.She has gone to
【答案】D
【详解】句意:——格林女士现在在办公室吗?——不在。她去图书馆了。
考查have been to和have gone to的区别。have been to+地点,表示曾经去过某地,已经回来;have gone to+地点,表示已经去了某地,还没回来。Ms. Green是女性,应用she指代,排除A、B;根据回答“no”可知格林女士现在不在办公室,是去了图书馆还没回来,用“has gone to”。故选D。
2.—Sorry, Miss Tang, I am late.
—It doesn’t matter. The class ________ for just several minutes. You don’t miss too much.
A.began B.has begun C.has been on D.is beginning
【答案】C
【详解】句意:——抱歉唐老师,我迟到了。——没关系,课程才开几分钟。你没有错过太多。
考查动词时态。根据“for just several minutes”可知,时态用现在完成时have/has done,且与一段时间连用,动词用延续性动词;根据“You don’t miss too much.”可知,是指课程才开几分钟,begin“开始”,是短暂性动词,应转为对应的延续性动词be on。故选C。
3.Astronauts (宇航员) on the Chinese Space Station _______ some plants already, and it helps us learn about living in space.
A.grew B.were growing C.have grown D.will grow

【详解】句意:中国空间站上的宇航员已经种植了一些植物,这有助于我们了解太空生活。
考查动词时态。根据“already”是现在完成时的标志词可知,此处用现在完成时(have/has done),故选C。
二.正确形式填空
1.Linda has not (realize) the importance of doing exercise.
【答案】realized
【详解】句意:琳达还没有意识到锻炼的重要性。根据“has”可知,此处是现在完成时,故空处应该填realize的过去分词realized。故填realized。
2.The government (try) to stop people from littering recently.
【答案】has tried
【详解】句意:政府最近试图阻止人们乱扔垃圾。根据“recently”可知,句子时态为现在完成时,其结构为have/has done;主语“The government”为第三人称单数,助动词用has,动词try的过去分词为tried。故填has tried。
3.It has been five years since he (teach) at primary school.
【答案】taught
【详解】句意:自从他在小学教书已经有五年了。teach“教,教授”,动词;根据“It has been five years since he”可知,since引导时间状语从句时,表示“自从……以来”,主句常用现在完成时,从句常用一般过去时,所以动词使用过去式。故填taught。
4.—Can I use the computer to search for information now?
—Of course, we (repair) it. Help yourself!
【答案】have repaired
【详解】句意:——我现在可以用电脑搜索信息吗?——当然,我们已经修好了。请自便!根据答语“Of course...Help yourself!”可知这里说的是已经修好了电脑,所以时态应该用现在完成时,基本构成:have/has+动词的过去分词,主语是we,复数形式,所以助动词用have,故填have repaired。
5.Have you ever (write) to your parents to ask for help?
【答案】written
【详解】句意:你曾经写信给你的父母求助了吗?根据助动词“have”可知句子时态为现在完成时,其谓语结构为“have/has+done”,故填written。
6.He to London. He will be back in two weeks. (go)
【答案】has gone
【详解】句意:他去伦敦了。 他将在两周后回来。根据“He will be back in two weeks”可知,去了伦敦还未回来,用have/has gone to表示“去了某地”,主语he是第三人称单数形式,助动词用has,故填has gone。
7.I have the book for two days. (keep)
【答案】kept
【详解】句意:这本书我已经借了两天了。根据空前的have及空后的for two days可知,句子是现在完成时,空处动词用过去分词形式kept。故填kept。
8.25 years (pass) since Hong Kong returned to China.
【答案】has passed
【详解】句意:距离香港回归中国已经过去25年了。根据下文“since Hong Kong returned to China”可知,句子应用现在完成时,即“have +过去分词”结构。表时间长度、钱数、速度等的词组作主语时,此时通常将其视为整体,谓语用单数,主语为“25 years”,故have应用第三人称单数形式has,故填has passed。

1.你已经看过这部电影了吗?
2.我已经买这本词典三年了。
【答案】1.Have you seen this film yet?
2.I have had this dictionary for 3 years.
时态的判定
初中阶段需掌握六种基本时态。学生可根据以下5点来判断不同时态的选用。
(1)巧用提示辨时态
遇到时态题时,首先要寻找时间标志词,如果题干中有时间标志词,可以根据时间状语选择相应的时态。需要注意的是,个别时间状语可用于不同的时态中,考生需具体情况具体对待。
如:I a high school student this September.I can’t wait!
A. am B. was
C. have been D. will be
方法点拨 第1步:分析语境:今年九月我就会是一名高中生了。我等不及了! 第2步:分析选项,A项:一般现在时;B项:一般过去时;C项:现在完成时;D项:一般将来时。第3步:根据时间状语this September以及句子描述可知选D。
(2) 细心体会辨语境
在有些情况下,动词的时态是由上下文语境来决定的,这就要求我们既要理解上下文的语境,也要掌握各种时态的灵活运用。
如果一个英语句子中既没有出现时间状语,也没有可供判断时态的上下文,那么就应当把这个句子翻译成中文,利用我们的母语知识来判断这个句子该用何种时态。
如: —Where is Miss Li?—She ___ the laboratory.
A. is going to B. has gone to
C. went to D. goes to
方法点拨 第1步:分析语境“李老师在哪里?” “她去实验室了。”第2步:分析选项,A项:一般将来时;B项:现在完成时;C项:一般过去时;D项:一般现在时。第3步:结合语境可知这里指“李老师去图书馆的动作发生在过去,在双方说话时她还没回来”,应用现在完成时,故选B。
(3) 主从时态须呼应
主从复合句中谓语动词时态的一致主要有以下几种情况:
①“主将从现”原则。如果主句是一般将来时,从句是由 when, after, before, not...until, as soon as 等引导的时间状语从句以及由 if, unless 引导的条件状语从句时,谓语动词应用一般现在时表示将来时。
如:He is going to be a scientist when he ____up.
A. grows B. grew
C. will grow D. has grown
方法点拨 when引导的时间状语从句遵循“主将从现”原则,即主句用一般将来时,从句需用一般现在时。故选A。
②在主从复合句中,如果主句和从句的谓语动词表示的两个动作都发生在过去,而且有明显的先后顺序,那么,延续性动词用过去进行时,短暂性动词用一般过去时。通常在when和while引导的时间状语从句中出现。
如: The children ___ a picnic in the park when it suddenly began to rain.
A. have B. are having
C. had D. were having
方法点拨 找出题目中的关键词“when”。when引导的时间状语从句的时态为一般过去时,且“began”为短暂性动词,主句表示延续性的动作,谓语动词应用过去进行时。故选D。
③在含有“since从句”的主从复合句中,主句常用现在完成时,从句常用一般过去时。另外,在“It’s+一段时间+since+从句”句式中,since 后面的从句常用一般过去时。
如: —Long time no see!—Oh! It five years since we met last time.
A. was B. were
C. has been D. have been
方法点拨 句意为“好久不见!”“哦!自从我们上次见面以来已经五年了。”since是现在完成时态的标志词,因此主句应用现在完成时态。主语It是第三人称单数,谓语动词应用has。故选C。
④当主句谓语动词的时态为一般现在时、现在进行时、现在完成时等时态时,后面跟的宾语从句中的谓语动词的时态不受主句时态的限制,可根据具体情况,选用各种合适的时态。
如:I don’t know if he ___ to play basketball with us.
A. comes B. came
C. will come D. has come
方法点拨 句意为:我不知道他是否会来和我们一起打篮球。if作为“是否”讲,宾语从句中的谓语动词的时态不受主句时态的限制,因为事情还没有发生,应用一般将来时。故选C。
⑤“时态一致”原则。在含有宾语从句的主从复合句中,当主句的谓语动词为过去时态时,从句的谓语动词需用相应的某种过去时态。
如:I didn’t understand ___, so I raised my hand to ask.
A. what my teacher says B. what does my teacher say
C. what my teacher said D. what did my teacher say
方法点拨 第1步:分析选项可知本题考查宾语从句的语序及时态。宾语从句需用陈述句语序,排除B和D项。第2步:根据“时态一致”原则,即主句的谓语动词为过去时态,从句的谓语动词需用相应的某种过去时态。故选C。
(4)上下一致定时态
在这种情况下,动词的时态是由上下文已有的时态信息来确定,这就要求我们准确判断上下文所表达的时态信息,确定恰当的时态。
如: —I can’t find David. Where is he?—He for tomorrow’s competition at home.
A. prepares B. prepared
C. is preparing D. has prepared
方法点拨 第1步:分析语境:“我找不到大卫。他在哪儿?”“他正在家里为明天的比赛做准备。”第2步:问句为一般现在时,可知答语表示他此刻正在为明天的比赛做准备,应用现在进行时,故选C。
(5)瞻前顾后巧搭配
在英语中,不少句型与一些动词在时态的运用方面都存在着特定的对应关系。
①在“祈使句+and/or+陈述句”句型中,陈述句中用will表示一般将来时。
如:Hurry up, or you ____ the early bus.
A.miss B. missed C. will miss D. have missed
方法点拨 分析句子结构可知这是“祈使句+or +陈述句”句型,陈述句的谓语要用“will+动词原形”,故选C。
②在This/That/It is the first time that...
句型中用现在完成时。若is改为was,就用过去完成时,有时以上结构中的 first 也可换成 second, third, fourth 等,其中的time也可换成其他名词。
如:This is the first time that I ___ a baseball game.
A. am watching B. was watching
C. have watched D. will watch
方法点拨 分析句子结构可知此处考查This is the first time…句型,后面所加从句应用现在完成时。故选C。

一.单项选择
1.The girl ________ is reading under the tree ________ my sister.
A.which; is B.whom; was C.who; is D.who; was
【答案】C
【详解】句意:在树下看书的那个女孩是我妹妹。
考查定语从句和时态。which引导定语从句,先行词为物,在从句中作主语或宾语;whom引导定语从句,先行词为人,在从句中作宾语;who引导定语从句,先行词是人,在从句中作主语或宾语。第一空,分析句子结构可知,此处考查定语从句,先行词“The girl”指人,且在从句中作主语,应用关系代词who来引导从句,排除A和B;第二空,根据“is reading under the tree”可知,句子陈述现在的情况,时态应用一般现在时。故选C。
2.— Music and Art will enter the Entrance Examination for the high school. Is it true?
— Yes. But don’t worry. Nothing will be difficult if more attention ________ to them.
A.will pay B.will be paid C.pays D.is paid
【答案】D
【详解】句意:——音乐和美术将进入高中入学考试。这是真的吗? ——是的。不过别担心。如果对它们多加注意,没有什么是困难的。
考查一般现在时的被动语态。句子主语“more attention”与动词pay为被动关系,应用被动语态;根据“Nothing will be difficult if more attention … to them.”可知,此处为if引导的条件状语从句,符合“主将从现”原则,主句为一般将来时,则从句应用一般现在时,因此这里应用一般现在时的被动语态,其结构为be done,主语为第三人称单数,be动词用is,pay的过去分词为paid。故选D。
3.I can’t find my pen. I think somebody must ________ it up.
A.had picked B.has picked C.have picked D.pick
【答案】C
【详解】句意:我找不到我的笔。我认为有人一定拿走了它。
考查动词时态和语态。根据“I can’t find my pen.”可知,这里应该使用完成时,表示动作已完成,且这个动作对现在造成了影响,即我现在找不到我的笔。情态动词must后接动词原形。故选C。
4.Our class are going to have a picnic tomorrow. If you don’t go, ________.
A.so do I B.neither do I C. neither will I D. either will I
【答案】C
【详解】句意:我们班明天要去野餐。如果你不去,我也不去。
考查倒装句。根据“If you don’t go,”可知,句子为含if引导的条件状语从句的复合句,遵循“主将从现”原则,从句为一般现时,主句应用一般将来时,排除A和B;从句为否定句,主句部分表示“某人也不会去”,应用neither来引导倒装句,即neither will+主语。故选C。
5.—When shall we go and play basketball?
—Not until the work ________ tomorrow.
A.is finished B.have finished C.will be finished D.will finish
【答案】A
【详解】句意:——我们将什么时候去打篮球?——直到明天工作被完成。
考查主将从现。分析答语可知句子为含有until引导时间状语从句的复合句,遵循“主将从现”的原则,此处从句时态为一般现在时,而主语work和谓语动词finish之间是被动关系,应用被动语态,其谓语结构为“be+done”,故选A。
6.Linda is excited about the coming weekend because she ________ several old friends.
A.sees B.saw C.has seen D.is going to see
【答案】D
【详解】句意:琳达对即将到来的周末很兴奋,因为她打算去见几个老朋友。
考查一般将来时。sees看见,三单;saw看见,一般过去式;has seen已经见了,现在完成时;is going to see打算去见。根据“Linda is excited about the coming weekend because she”可知即将到来的周末表将来。见一些老朋友是将来打算好的事情。故选D。
7.—Why didn’t you come to the party last night?
—I don’t like staying with others. I ________ reading alone instead.
A.prefer B.enjoyed C.suggest D.dislike
【答案】A
【详解】句意:——你昨晚为什么没来参加派对?——我不喜欢和其他人待在一起。我宁愿一个人读书。
考查代词辨析。prefer更喜欢;enjoyed喜欢;suggest建议;dislike不喜欢。根据“don’t”可知,此句是陈述事实,句子用一般现在时,排除B选项。根据“I don’t like staying with others”及“reading alone instead”可知,与跟其他人待在一起相比,更喜欢独自看书,故选A。
8.Justin can’t help me to move the piano because he ________ English online.
A.is studying B.studied C.will study D.studies
【答案】A
【详解】句意:贾斯汀帮不了我搬钢琴,因为他正在网上学习英语。
考查动词时态。根据“Justin can’t help me to move the piano”可知,此处是正在网上学习,不能帮忙,可知用现在进行时,其结构是be doing的形式,主语是he,是第三人称单数,be动词用is,study“学习”,是动词,现在分词是studying。故选A。
9.By the time we ________ the railway station, the train ________ for ten minutes.
A.got to; had been away B.reached; had left
C.arrived; had been away D.arrived at; has left
【答案】A
【详解】句意:到我们到达火车站时,火车已经开走十分钟了。
考查动词(短语)辨析和延续性动词。get to/reached/arrived at都表示“到达”,后可直接跟地点;arrived是不及物动词,需和介词at/in搭配使用后才可跟地点,故排除C;根据“for ten minutes”可知,第二空要用延续性动词,left是leave“离开”的过去分词,是短暂性动词;而be away是延续性动词,且“火车离开”的动作发生在“到达车站”的动作之前,表示过去的过去,应用过去完成时。故选A。
10.—Did you see Linda come back last night?
—No, she (study) for an exam all the night in the school library.
【答案】was studying
【详解】句意:——你昨晚看到琳达回来了吗?——没有,她整晚都在学校图书馆里准备考试。根据“…for an exam all the night in the school library.”词可知,她整晚都在学校图书馆里准备考试,表达持续性行为,所以用进行时态,又结合问句中“last night”可知,时态为过去进行时,又由主语是she,此处过去进行时的结构为:was+现在分词,study的现在分词是studying。故填was studying。
二.时态填空

[答案]
1.choice 2.having/to have 3.why 4.on/of 5.simply
6.an 7.chatting 8.more delicious 9.will value 10.itself
[解析]
1.考查名词。由空前的unhappy about the可知,此处要用choose的名词形式作宾语,故填choice。

9.考查动词的时态。根据时间状语in the future可知,设空处要用一般将来时,故填will value。
10.考查反身代词。此句想表达的意思是“对我来说,一起准备年夜饭的过程比年夜饭本身更重要”,由此可知,此处要用反身代词,故填itself。
