【分析】—他在那里玩得开心吗？—不。我认为不是那样。
【解答】答案：D. 根据题意，—他在那里玩得开心吗？—不。我认为不是那样。本题考查助动词的用法。由答句中的don't之间，题干中为一般现在时，问句中主语为he，故用助动词does，后面的动词需要还原为原形，故填enjoy.

【分析】似乎木兰将面对一个新的角色，名叫陈红辉，以一个"刻薄、欺负人的性格"的士兵的身份出现，他不喜欢木兰超越自己的能力，直到他意识到她是一个女人．
【解答】考查助动词的用法．根据句子的谓语部分It seems that以及until引导的时间状语从句until he realize she is a woman可知，句子使用的是一般现在时，描述的是对事情的一种主观的判断，所以who引导的定语从句也使用一般现在时，who替代的先行词为a soldier，为第三人称单数，所以空格处使用助动词does not+动词原形．
故选：A．

A．do devote B．to devote C．devoting D．devoted

故选：A。
5．Among those contributing a lot to the Hope Project ________ a famous star， who graduated from our school．（ ）
A．are B．have C．is D．has
【分析】在这许希望工程的捐助者中有一位明星， 他是从我们学校毕业的．
【解答】答案： C 本句考查联系助动词的单复数形式． 题干主句是一个完全倒装句， 主语是a famous star是第三人称单数， 所以谓语动词应用单数is．
故选：C．
6．An awful accident __________， however，occur the other day．（ ）
A．does B．did C．has to D．had to
【分析】然而，几天前，一场可怕的事故确实发生了．
【解答】答案：B．根据句意和时间状语the other day可知用一般过去时，排除AC，D项不符合句意．使用助动词did是对谓语动词occur的强调．故选B．
7．If you have made your decision，________ yourself to it until you accomplish your goal．（ ）
A．devoting B．not devoting
C．do devote D．don't devote
【分析】如果你已经做出了决定，致力于此，直到你完成你的目标．
【解答】C
解答：考查助动词．根据题意，此句是if从句+祈使句这样的结构，祈使句动词前加上do表示强调，故用do devote．
故选：C．
8．I believe that you are a nice friend．（ ）
A．am B．do C．did D．was
【分析】我的确相信你是一个好朋友．
【解答】答案：B，"Do+动词原形+其他成分"表示加强语气，起强调作用，AD排除，C强调谓语动词用在过去时态中，

9．In my opinion，all Mr．Li good to his students in his class at present．He is very strict with them in their studies．（ ）
A．．does does does B．does does do
C．does do did D．did do does
【分析】句意：依我看，李先生现在所做的一切都对他班上的学生有好处，他在学习上对他们要求很严格．
【解答】答案：B．does does do 考查助动词辨析．根据题干此处表达的意思是：李先生现在所做的一切都对他班上的学生有好处，他在学习上对他们要求很严格．all does do good to his students in his class at present．He is very strict with them in their studies．是主干，其中do good to译为：对…有好处，"all"是单数形式，要用"does"；第一个"does"是"all"的定于，即all （that） does译为所做的一切．故选：B。
10．"Each of the students， working hard at his or her lessons， ____to go to university．" "So_____I．"（ ）
A．hope； do B．hopes； do C．hoping； am D．hopes； am
【分析】"每个努力学习功课的学生都希望上大学．""我也是．"
【解答】本题考查助动词．根据句意和结构可知这里第一空谓语动词，主语是Each of the students，使用一般现在时，谓语是三单，第二空使用助动词do，句型是So+助动词/be/情态动词+主语，意为"…也是"．
故选：B．
11．Lisa_______me to attend the meeting at two in the afternoon，but I completely forgot．（ ）
A．does have told B．did have told
C．did tell D．does tell
【分析】Lisa的确告诉我下午两点去参加会议，但我完全忘记了．
【解答】答案：C
根据题干"but I completely forgot"可知，Lisa曾经告诉过我参加会议的事，故用一般过去时．另外，句子还有强调的意思，即"的确，确实告诉过我"，结构为did+动词原形．英语中对动词强调结构为：助动词do+动词原形，注意do有时态和人称的变化．
故选：C。
12．In my opinion，all Mr Li ______ good to his students in his class at present．He is very strict with them in their studies．（ ）
A．does does does B．does does do
C．does do did D．did do does
【分析】在我看来，李老师目前在课堂上所做的事情的确对学生非常好．在学习上严格要求学生．
【解答】答案；B
分析句子结构得知，主句为"All does do good to his students in his class at present．"其中谓语是一个短语"do good to"意为"对…有好处"，然后对其突出强调，结构为：助动词do+动词原形，因为主语all为单数，故用does强调．另外，Mr Li does为定语从句修饰先行词all，does为谓语动词，意为"做"，所以答案选择B．
13．﹣Tell me your secret．
﹣I ______．It wouldn't be a secret if I told you．（ ）
A．won't B．needn't C．mightn't D．couldn't
【分析】﹣﹣﹣请告诉我你的秘密．
﹣﹣﹣我不会告诉你的．如果我告诉你那就不是秘密了．
【解答】答案：A
由于第一句Tell me your secret．是省略了主语you的祈使句，祈使句的动作通常表示在将来发生的动作，所以作答时，一般用will或won't；根据后面的答语"…如果我告诉你那就不是秘密了．"可知，我是不会告诉你的，所以要用否定形式．故选A
14．﹣Mom!Jack has broken a cup!
﹣Doesn't matter．Accidents ________ happen．（ ）
A．should B．must C．will D．shall
【分析】﹣﹣妈妈，Jack 打破了一个杯子．
﹣﹣没关系．一些事故在所难免．
【解答】答案：C．
will用于一般的习惯、倾向或表示固有性质．如：People will talk．人总会说闲话．
故选：C。
15．﹣Alan seems a lot taller than when I last saw him．
﹣He ________．He's grown a foot since you saw him in Shanghai．（ ）
A．is B．will be C．has been D．was
【分析】Alan好像比我上次见到他要高很多了．他的确高了．自从你在上海见到他之后他又长了一英尺．
【解答】答案：A．
根据后面的陈述He's grown a foot since you saw him in Shanghai．说明孩子真的长高了很多，所以前面一句是回答对方说现在他的确很高了．即He is a lot taller now than you last saw him．
故选：A。
16．That's why I help brighten people's days．If you __________，who is to say that another person will？（ ）
A．didn't B．don't C．weren't D．haven't
【分析】那就是我为什么帮助照亮人们生活的原因．如果你不这样做，谁又能保证别人就会去做呢？
【解答】答案：B
后一句是if引导的条件状语从句，主句用一般将来时，从句用一般现在时代替．而A、C两项是过去式；D项是现在完成时，与题干不符．只有助动词do可代替实意动词．故选B．
17．Mom，you promised to read me a story every night as long as I behave well，so you must ______．（ ）
A．do it B．do reading it
C．read a story D．do reading
【分析】妈妈，你答应过我只要我表现好，你每晚都会读故事的，所以你必须做到．
【解答】答案：A
must为情态动词，后需加动词原形．如果前面出现一个动词，后面再次出现则用助动词do来代替，do it代指前文的read me a story every night，故选A．
18．It's reported that the future generations are going to live longer than we ______ now．（ ）
A．are B．do C．will D．have
【分析】据报道，未来的人们将会比我们现在活的时间更长．
【解答】答案为B
分析这个句子，应该是"…live longer than we live now"，为避免重复用do来替代live．
19．The earth is our only home．If we don't care about it，who else ______？（ ）
A．was B．does C．will D．has
【分析】地球是我们唯一的家．如果我们不关心它，谁会关心呢？
【解答】答案：C．考查时态．if引导的条件状语从句，主句应为一般将来时，所以用will．
20．﹣﹣﹣I'm sorry．I should not have been so rude to you．
﹣﹣﹣You something not very nice to me，but that's OK．（ ）
A．have said B．had said
C．were saying D．did say
【分析】﹣﹣﹣很抱歉，我本不应该对你这么粗鲁．
﹣﹣﹣你的确对我说了一些不太友好的话，不过没有关系啦．
【解答】答案：D
根据前句"I should not have been so rude to you"可知是表示"本不应该做但实际上做了"．所以回答句陈述的是发生在过去的一件事，并且强调前者的确做了这样一件事，结构为"did+do"．如果对动词进行强调，结构为：do+动词原形，其中do为助动词，有时态和人称的变化，如；第一人称do，第三人称does，过去时did．
21．﹣﹣﹣Tom failed again!
﹣﹣﹣If he had spent as much as he _______ on computer games．（ ）
A．has B．had C．did D．would
【分析】﹣﹣﹣Tom又失败了！
﹣﹣﹣如果他花的时间能像在电脑游戏上那么多就好了．
【解答】答案：C
根据回答句可知，是在陈述Tom失败的原因，即没有花时间在这件事上．但没有从正面直接说，用虚拟语气"如果花的时间和在电脑游戏上花的一样多"来表达．此处did代指前面出现的动词"spent"，意为"花费"符合题意．当前面出现一个动词，后面再次出现，需用助动词do来代替．注意do的三种形式：do，does和did．
22．I saw Tom in the meeting﹣room，so he attend the meeting．（ ）
A．surely B．did C．does D．really
【分析】我看见Tom在会议室里了，他一定出席这个会议了．
【解答】答案：B．根据上文时态可知句子应该用一般过去时，题目中动词用了原形，所以只有选项B能帮助句子构成过去时态，本题中助动词表示强调．
23．Listening to loud music at rock concerts caused hearing loss in some teenagers．（ ）
A．is B．are C．has D．have
【分析】在摇滚音乐会上听大声的音乐会造成一些青少年的听力损失．
【解答】答案C．
这个句子已经有个谓语动词（caused），并且这个动词有自己的宾语（hearing loss in some teenagers），所以主语（listening to loud music at rock concerts）不是这个谓语动词的承受者，没有被动关系．故排除A、B．主语是动名词（listening to…），应用单数，故选C．
24．How many nationalities ______ your country ______？（ ）
A．is； consisted of B．does； make up
C．is； made from D．does； consist of
【分析】这个国家由多少个民族组成？
【解答】答案D
解析：考查助动词和动词短语：．consist of由什么组成，无被动语态无进行时态，相当于be made up of，make up组成；be made from由…制成．consist of是实意动词，借助于助动词does构成疑问句．
故选：D．
25．Most insurance agent（保险公司）would rather you _______ anything about collecting claims until they investigate the situation．（ ）
A．do B．don't C．didn't D．didn't do
【分析】大多数的保险公司在你索赔这件事情上宁愿你不做任何事情， 直的他们对这件事情调查清楚为止．
【解答】按照题目的意思应该什么都不做，但would rather 后面加句子用虚拟语气，对现在的虚拟宾语从句要用过去时，所以是didn't do．
故选：D．
26．An awful accident，however，________ occur again at the railroad crossing the other day．（ ）
A．did B．does C．has to D．had to
【分析】然而，前一天，一场严重的车祸又一次在铁路十字路口处发生了．
【解答】句末的the other day意为"前几天"，所以句子应用过去时态，而选项D填进去不合题意，此句有两个难点：一是句中插有however一词，分散了同学们的注意力；二是所填选项B为许多同学所不熟悉的强调用法，此处强调的是谓语动词．
故选：A．
27．The boy ___________ go to a movie last night．（ ）
A．does B．has C．did D．was
【分析】这个男孩昨晚确实去了电影院．
【解答】答案：C．根据句意可知这里考查使用助动词do，does或者did强调谓语的用法，因为时间是last night，用助动词did+动词原形．
故选：C．
28．Coal is hard， like a rock and yet it burns， while no rocks ______．（ ）
A．do B．does C．are D．is
【分析】煤是硬的，像岩石，但它燃烧，而岩石不会燃烧．
【解答】本题考查助动词．根据句意和结构可知while后面使用省略句．用助动词do指代上文的burn．不是be动词，rocks是复数，不能用does．
故选：A．

9．In my opinion，all Mr．Li good to his students in his class at present．He is very strict with them in their studies．（ ）
A．．does does does B．does does do
C．does do did D．did do does
【分析】句意：依我看，李先生现在所做的一切都对他班上的学生有好处，他在学习上对他们要求很严格．
【解答】答案：B．does does do 考查助动词辨析．根据题干此处表达的意思是：李先生现在所做的一切都对他班上的学生有好处，他在学习上对他们要求很严格．all does do good to his students in his class at present．He is very strict with them in their studies．是主干，其中do good to译为：对…有好处，"all"是单数形式，要用"does"；第一个"does"是"all"的定于，即all （that） does译为所做的一切．故选：B。
10．"Each of the students， working hard at his or her lessons， ____to go to university．" "So_____I．"（ ）
A．hope； do B．hopes； do C．hoping； am D．hopes； am
【分析】"每个努力学习功课的学生都希望上大学．""我也是．"
【解答】本题考查助动词．根据句意和结构可知这里第一空谓语动词，主语是Each of the students，使用一般现在时，谓语是三单，第二空使用助动词do，句型是So+助动词/be/情态动词+主语，意为"…也是"．
故选：B．
11．Lisa_______me to attend the meeting at two in the afternoon，but I completely forgot．（ ）
A．does have told B．did have told
C．did tell D．does tell
【分析】Lisa的确告诉我下午两点去参加会议，但我完全忘记了．
【解答】答案：C
根据题干"but I completely forgot"可知，Lisa曾经告诉过我参加会议的事，故用一般过去时．另外，句子还有强调的意思，即"的确，确实告诉过我"，结构为did+动词原形．英语中对动词强调结构为：助动词do+动词原形，注意do有时态和人称的变化．
故选：C。
12．In my opinion，all Mr Li ______ good to his students in his class at present．He is very strict with them in their studies．（ ）
A．does does does B．does does do
C．does do did D．did do does
【分析】在我看来，李老师目前在课堂上所做的事情的确对学生非常好．在学习上严格要求学生．
【解答】答案；B
分析句子结构得知，主句为"All does do good to his students in his class at present．"其中谓语是一个短语"do good to"意为"对…有好处"，然后对其突出强调，结构为：助动词do+动词原形，因为主语all为单数，故用does强调．另外，Mr Li does为定语从句修饰先行词all，does为谓语动词，意为"做"，所以答案选择B．
13．﹣Tell me your secret．
﹣I ______．It wouldn't be a secret if I told you．（ ）
A．won't B．needn't C．mightn't D．couldn't
【分析】﹣﹣﹣请告诉我你的秘密．
﹣﹣﹣我不会告诉你的．如果我告诉你那就不是秘密了．
【解答】答案：A
由于第一句Tell me your secret．是省略了主语you的祈使句，祈使句的动作通常表示在将来发生的动作，所以作答时，一般用will或won't；根据后面的答语"…如果我告诉你那就不是秘密了．"可知，我是不会告诉你的，所以要用否定形式．故选A

A．is B．will be C．has been D．was
【分析】Alan好像比我上次见到他要高很多了．他的确高了．自从你在上海见到他之后他又长了一英尺．
【解答】答案：A．
根据后面的陈述He's grown a foot since you saw him in Shanghai．说明孩子真的长高了很多，所以前面一句是回答对方说现在他的确很高了．即He is a lot taller now than you last saw him．
故选：A。

A．didn't B．don't C．weren't D．haven't
【分析】那就是我为什么帮助照亮人们生活的原因．如果你不这样做，谁又能保证别人就会去做呢？
【解答】答案：B
后一句是if引导的条件状语从句，主句用一般将来时，从句用一般现在时代替．而A、C两项是过去式；D项是现在完成时，与题干不符．只有助动词do可代替实意动词．故选B．

A．do it B．do reading it
C．read a story D．do reading
【分析】妈妈，你答应过我只要我表现好，你每晚都会读故事的，所以你必须做到．
【解答】答案：A
must为情态动词，后需加动词原形．如果前面出现一个动词，后面再次出现则用助动词do来代替，do it代指前文的read me a story every night，故选A．
18．It's reported that the future generations are going to live longer than we ______ now．（ ）
A．are B．do C．will D．have
【分析】据报道，未来的人们将会比我们现在活的时间更长．

【分析】地球是我们唯一的家．如果我们不关心它，谁会关心呢？

﹣﹣﹣You something not very nice to me，but that's OK．（ ）
A．have said B．had said
C．were saying D．did say
【分析】﹣﹣﹣很抱歉，我本不应该对你这么粗鲁．
﹣﹣﹣你的确对我说了一些不太友好的话，不过没有关系啦．
【解答】答案：D
根据前句"I should not have been so rude to you"可知是表示"本不应该做但实际上做了"．所以回答句陈述的是发生在过去的一件事，并且强调前者的确做了这样一件事，结构为"did+do"．如果对动词进行强调，结构为：do+动词原形，其中do为助动词，有时态和人称的变化，如；第一人称do，第三人称does，过去时did．
21．﹣﹣﹣Tom failed again!
﹣﹣﹣If he had spent as much as he _______ on computer games．（ ）
A．has B．had C．did D．would
【分析】﹣﹣﹣Tom又失败了！
﹣﹣﹣如果他花的时间能像在电脑游戏上那么多就好了．
【解答】答案：C
根据回答句可知，是在陈述Tom失败的原因，即没有花时间在这件事上．但没有从正面直接说，用虚拟语气"如果花的时间和在电脑游戏上花的一样多"来表达．此处did代指前面出现的动词"spent"，意为"花费"符合题意．当前面出现一个动词，后面再次出现，需用助动词do来代替．注意do的三种形式：do，does和did．
22．I saw Tom in the meeting﹣room，so he attend the meeting．（ ）
A．surely B．did C．does D．really
【分析】我看见Tom在会议室里了，他一定出席这个会议了．

23．Listening to loud music at rock concerts caused hearing loss in some teenagers．（ ）
A．is B．are C．has D．have
【分析】在摇滚音乐会上听大声的音乐会造成一些青少年的听力损失．
【解答】答案C．
这个句子已经有个谓语动词（caused），并且这个动词有自己的宾语（hearing loss in some teenagers），所以主语（listening to loud music at rock concerts）不是这个谓语动词的承受者，没有被动关系．故排除A、B．主语是动名词（listening to…），应用单数，故选C．
24．How many nationalities ______ your country ______？（ ）
A．is； consisted of B．does； make up
C．is； made from D．does； consist of
【分析】这个国家由多少个民族组成？
【解答】答案D
解析：考查助动词和动词短语：．consist of由什么组成，无被动语态无进行时态，相当于be made up of，make up组成；be made from由…制成．consist of是实意动词，借助于助动词does构成疑问句．
故选：D．
25．Most insurance agent（保险公司）would rather you _______ anything about collecting claims until they investigate the situation．（ ）
A．do B．don't C．didn't D．didn't do
【分析】大多数的保险公司在你索赔这件事情上宁愿你不做任何事情， 直的他们对这件事情调查清楚为止．
【解答】按照题目的意思应该什么都不做，但would rather 后面加句子用虚拟语气，对现在的虚拟宾语从句要用过去时，所以是didn't do．
故选：D．
26．An awful accident，however，________ occur again at the railroad crossing the other day．（ ）
A．did B．does C．has to D．had to
【分析】然而，前一天，一场严重的车祸又一次在铁路十字路口处发生了．
【解答】句末的the other day意为"前几天"，所以句子应用过去时态，而选项D填进去不合题意，此句有两个难点：一是句中插有however一词，分散了同学们的注意力；二是所填选项B为许多同学所不熟悉的强调用法，此处强调的是谓语动词．
故选：A．
27．The boy ___________ go to a movie last night．（ ）
A．does B．has C．did D．was
【分析】这个男孩昨晚确实去了电影院．
【解答】答案：C．根据句意可知这里考查使用助动词do，does或者did强调谓语的用法，因为时间是last night，用助动词did+动词原形．
故选：C．
28．Coal is hard， like a rock and yet it burns， while no rocks ______．（ ）
A．do B．does C．are D．is
【分析】煤是硬的，像岩石，但它燃烧，而岩石不会燃烧．
【解答】本题考查助动词．根据句意和结构可知while后面使用省略句．用助动词do指代上文的burn．不是be动词，rocks是复数，不能用does．
故选：A．
