champion冠军。故选A。2B解析：B【解析】试题分析：考查冠词。元音开头的此前用an表示“一”；辅音开头的此前用“a”表示“一”。故选B。考点：考查冠词3B解析：B【解析】句意：那时我们在史密斯家有一段多么美好的日子呀！第一空：time 在这指日子，时期。是可数名词所以用a,第二空：the+ Smiths,指史密斯一家，所以选B。4B解析：B【解析】【详解】考查冠词。句意：我们去看电影吧！这会让你的注意力远离这个问题一段时间。第一空为固定词组go to the cinema“去看电影”；第二空也是固定词组for a while“一会儿”。故选B。5A解析：A【详解】试题分析：句意：你长大了想干什么？像朱军这样的主持人。根据句意及题干分析此空是泛指像朱军一样的主持人，host以元音音素开头，其前ong不定冠词a。故选A。考点：考查冠词的用法6A解析：A【详解】句意：这台新电脑是你妈妈送给你的生日礼物吗？ 是的。我从没见过比这更好的。 考查冠词。a/an不定冠词，表泛指；the定冠词，表特指；第一个空后的 new computer被“your mother gave you as your birthday present”限定，因此，此处的新电脑表示特指，用定冠词the；第二个空是：否定词+比较级，表示最高级。故选A。二、选择题7C解析：C【详解】句意：女孩从爸爸那得到一辆新自行车，她非常喜欢它的颜色。考查代词辨析。it它，人称代词；itself它自己，反身代词；its它的；its它是。此空修饰名词colour，用形容词性物主代词。故选C。8C解析：C【详解】句意：你父母对你的英语很生气吗？ 哦，他们两个都不生气。他们只是告诉我下次要取得更好的成绩。 考查不定代词。none三者或三者以上都不；both两个都；neither两者都没有（作主语时，谓语用单数）；either二者选其一。根据“They just told me to get better grades next time.”可推出父母应该是不生气，再根据空格后谓语动词用的是is，可知此处需用neither符合语境。故选C。9D解析：D【详解】句意：现在的电视剧比以前多了。这是真的。但都不合我的口味。我更喜欢西方电视剧。考查不定代词。all都；few没有多少；some一些；none一个也没有。根据“but”及“I prefer westerns”可知，没有一个是自己喜欢的，故选D。10B解析：B【详解】句意：对不起，我想给我弟弟买一个生日礼物。这里有一些男孩的礼物。你可以为他选一个。考查不定代词。one/it/that三者均可用作代词，指代前面提到的名词。one表示泛指，that和it表示特指。that与所指名词为同类，但不是同一个，而it与所指名词为同一个。一般说来，it指代同名同物，one与that则指代同名异物。根据语境可知，空格处指代上述礼物中的一个，泛指，应用one。故选B。11B解析：B【详解】句意：如果出了什么问题，把它解决好。别担心。忧虑永远不会解决任何问题。考查不定代词。something某事；某物；anything任何事物；nothing没有什么；everything每件事。anything一般用于否定句和疑问句中；something则用在肯定句中；everything以单数形式表达所有的概念；nothing则表示什么都没有。因为句中有never，可知，本题是否定句，因此应该选择anything任何事物，表示：忧虑永远不会解决任何问题。故选B。三、选择题12D解析：D【详解】句意：我认为一些明星应该多注意他们的行为，因为他们所做的对青少年有很大的影响。考查名词辨析。change变化；impression印象；progress进步；influence影响。根据上文“I think some famous stars should pay more attention to their behavior”，可知是因为明星的行为对青少年有很大影响，故选D。四、选择题13D解析：D【详解】句意：这部无聊的肥皂剧你已经看了几千遍了！你为什么不出去找点值得做的事呢？考查形容词辨析。useful有用的；cheerful令人愉快的；enjoyable愉快的；worth值得的。根据前句“Youve watched the boring soap opera thousands of times!”和空后动词“doing”的形式可知，空处应是worth，值得的。故选D。14A解析：A【详解】句意：越来越多的人喜欢在微信上团购。 你说的对。这样价格要低得多。考查形容词比较级。much lower更低的；much cheaper更便宜的；more expensive更昂贵的；even higher更高的。根据上文“group buying on WeChat”及常识可知，团购价格通常比平时更优惠，故C、D选项可排除。形容价格的“低”应用形容词low，故选A。15B解析：B【详解】句意：春节是中国的传统节日之一，每个人都喜欢庆祝它。考查形容词辨析。modern现代的；traditional传统的；international国际的；ancient古代的。根据“everyone loves to celebrate it.”每个人都喜欢庆祝它，结合“The Spring Festival is one of the festivals in China”，以及常识，可知春节是中国的传统节日之一，故选B。16C解析：C【详解】句意：明天你愿意和我们一起去爬山吗？恐怕不能，那是世上我最不想做的事情。考查形容词。very非常；best最好的；last最后的；first 第一；根据题干结合“I am afraid not”推测设空处句子的句意是“恐怕不能，那是世上我最不想做的事情”，由此判断句子中缺少“最后的”一词，故答案为C。五、选择题17C解析：C【详解】句意：徐州地铁2号线于2020年11月28日正式投入使用，这是我们日常生活中最重要的事件之一。考查介词辨析。at后接点钟；in后接年、月、星期等大时间；on后接具体的某一天；for后接时间段。“November 28, 2020”指具体的某一天。故选C。六、选择题18D解析：D【详解】句意：上个月一家工厂发生了一场大火。对我们来说小心火是很重要的。考查动词短语辨析。put out扑灭；turned out证明是；got out出去；broke out爆发。根据“A big fire. in a factory last month.”可知，这里表示“火灾爆发”。故选D。七、选择题19C解析：C【详解】句意：佐伊，你认为网上购物最大的优势是什么？至少我不需要花很多时间逛商店。考查情态动词。shouldnt不应该；cant不能；neednt不需要；mustnt一定不要，禁止。根据句意可知，网上购物的最大优点是不需要花很多时间逛店。“neednt”表示“不需要”，故选C。八、选择题20D解析：D【详解】句意：看！过山车在以多么高的速度在运行呀！考查感叹句。感叹句主要有：how+形容词/副词+主语+谓语+其他！what+a/an（形容词）+单数名词+主语+谓语+其他！或者what+（形容词）+名词复数/不可数名词+主语+谓语+其他！该句中感叹名词speed，所以用what引导的感叹句，speed不可数名词；“以速度”用介词at，故选D。21A解析：A【详解】句意：和那个幽默的女孩在一起多有趣啊!考查感叹句。感叹句结构为What +(a/an) +形容词+名词+主语+谓语或How + 形容词/副词+主语+谓语，what用来感叹名词，how 用来感叹形容词或副词，此句用来感叹名词fun，所以用What，另外fun是不可数名词，所以不加a， 故选A。22D解析：D【详解】句意：长武路多么拥挤啊！是的，因为自从四月开始，车的数量持续增加了很多。考查感叹句和动词辨析。此句感叹句句型为“How+形容词+主语+谓语！”，排除A和C；raise和rise都可以用来表示数量时，raise是及物动词，倾向于人为或被动，而rise是不及物动词。故选D。九、选择题23B解析：B【详解】句意：鲍勃，你们多久能把产品准备好？我不确定。我还在等待最终的设计。考查疑问词辨析。how long 多久（时长），多长（长度）；how soon 多久以后（将来的时长）；how often 多久一次（频率）；how far 多远（距离）。根据答语可知，空处讨论的是将来所需的时间。故选B。24C解析：C【详解】句意：连接盐城到上海的高速铁路多久才能完工?大约六个月后。考查特殊疑问句。How long多长时间，提问for+一段时间；How far多远，提问两地之间的距离；How soon还有多久，提问in+一段时间；How often多久一次，提问频率；根据句意理解及回答In about six months可知，这里表达的“还有多久”，英语中对于“in+一段时间”的提问用how soon，故选C。十、选择题25D解析：D【详解】句意：当他出国留学时，他的父母和孩子都由他的妻子照顾得很好。考查一般过去时被动语态及动词短语。固定搭配：take good care of好好照顾，排除C选项。主语“his parents and children”与动词“take good care of”之间是被动关系，且根据“went”可知，此处应用一般过去时被动语态was/were done的结构，故选D。26C解析：C【解析】解析：句意：在瑞士，像玻璃和塑料都要被分成不同的类别，然后被回收再循环利用。根据选项中的动词separate，可知其含义为分离，主语为things like glass and plastic（像玻璃和塑料这种东西），可知主语是动作的承受者，故应该用被动语态（be+done）。句子描述的是一种客观事实，用一般现在时。主语things又是复数形式，故谓语动词应该用are。故答案选C。十一、选择题27D解析：D【解析】【详解】考查时态。句意：“这一时刻马上就要来了，”他想他等的都有点紧张了。先时后态，判断出时间为将来(soon)，就说明这一时刻还没到来但即将到来。用现在进行时表示一般将来时，A项一般过去时；B项现在完成时；C项过去将来时。故选D。28B解析：B【解析】考查时态.句意:今晚你想去看电影吗?对不起，我太累了。我想睡个早觉。某些的进行时态可以表示紧接着要发生的事情，故选B。29D解析：D【解析】试题分析： 考查动词的时态。句意：因为工人正在修理主管道，所以水供应暂时被切断。根据语境表示，修理管道这件事正在进行，所以选D项。考点 : 考查动词的时态30A解析：A【详解】句意：妈妈，我在忙着铺床。你能帮我一下吗？等一下。我正在扫地。考查动词时态。根据上文“Im busy making the bed.”可知，我正在忙着铺床，是现在进行时；且根据下文的“Wait a moment.”可知，妈妈要求等一下，此时她正在扫地，也用现在进行时，结构是am/is/are doing。故选A。十二、选择题31C解析：C【详解】句意：这些玩具真的很旧，但是我仍然想要保存他们。or或者，否则；and和，而且；but但是。根据句意，空前说really old，空后说want to keep them，前后为转折的关系，故应选C。32C解析：C【解析】这道题教我们正确的运用副词。先来翻译这段话，Bob很年轻，_他了解很多。填什么词会感觉语句通顺呢，A选项，因为；B选项，所以；C选项，但是；D选项，除非、故这道题我们选择C。33A解析：A【详解】解析：句意：他一直努力学习，因此他在许多方面取得了迅速的进步。A. so所以；B. because因为；C. but但是；D.
