讲解下这个英文选择题，

vocabulary and structure

1.“multiple-choicequestion”其实既可以指“单选题”，也可以指“多选题”。2.另外“单项选择题”，它还可以翻译为single-choicequestion.3.至于“选择题”，可以译为choicequestion或multiple-choicequestion.

6.HaveyouevervisitedtheleaningtowerinPisa?Oh,______A.dozensoftimesB.adozenoftimesC.dozensoftimeD.adozentimetime用来指次数时，是可数名词，用复数，timesadozenof后面可以加可数名词，也可以加不可数名词；dozensof，后面加可数名词复数A和B都可以，联系句意，回答者表示次数非常多，还是选择dozensof吧选A7.The_____towerlooksnice.A.twelve-metre-highB.twelve-metrehighC.twelve-metres-highD.Twelvemetrehigh十二米高，作形容词twelve-metre-high，都要连起来选A

C经理相信价格不会再次上涨4%。

chair一般用介词in，B选项比较合理。

第一空是形容词，意为。。。。的人们，所以用ed后缀，中间空是固定搭配，beconcerned with 是关于的意思，about是关心，关注，担心的意思，所以用about，最后一空，用来修饰facts的，具体concerned和concerning的区别，可以参见interested与interesting的区别

问题2＆3 （其他的问题被其他回答者们正确地回答了）Take part in = 参与 / 参加 (某些活动)Join/ Join in = 加入/参加 (某些社 / 俱乐部 / 会之类)这样应该比较容易明白吧？所以 2 同 3 都是 "to take part in"2. C took part in3. D took part in.

1. A considerate 母亲太体贴所以孩子不珍惜母亲的爱2.D demanding要求平等的权利3.D problem麻烦，问题4.A the total number of 是固定搭配，……的总数5.B whatever可以推断出只能选type，若是sor或kind应是whichever,variety 意为多样，更不和语境6.A lay emphasis on 是固定搭配 ，意为强调7.C recall one"s childhood回忆某人的童年8.B lost in thought 是固定搭配 陷入沉思9.A vary意为变化，价格根据质量变化而不是只上升或下降，exchange交换更不可能综上，这九道题基本都是词义辨析，想深刻理解的话可以去查字典，牛津双语字典最好～因为英语很多词意思相近但有细微不同，只看中文意思有时候难以分辨～所以可以去看牛津词典上的英文解释，这是个小秘诀呦(>^ω^<)

中国人学英文就是不行哎，不解释了

My holiday was very interesting. I reads two hours book everyday,then I go out to play. In this holiday,I watch a lot of movies, for example:Twilight and Inception.My classmates and I sometimes go out to go shopping. I have eaten a lot of food. At night,I always listen to my favourite music, play computer games and chat with my family members. How foolish am I! I copy this on the Internet!

我觉得应该选(A)

语感

我也选A，不过看了楼上的，觉得我已经什么都不用说了

B A

这就是中英两种语言文化的差异了! multiple choice 译成中文,为了方便大家理解,叫单项选择. 英语multiple choice的表述意思是：这题有多个备选项. 所以单项选择题=multiple choice 在各自的语言里,人们一般不会有疑问的.汉语里的“单项选择” 和“多项选择”,中国人是不会分不清的,就是要你“只选一项” 和“可选多项”嘛.以英语为母语的人 对 “Multiple Choice” 的理解 也不会有疑问.可是,一旦牵涉到两种语言,即当英语的“ Multiple Choice”被译成汉语的“单项选择”, 各种各样的疑问就来了. 对于“从多个选项中选一”的这类选择题,汉语叫“单项选择” 而英语是叫“ multiple choice ”.汉语中的“单项选择”是说“只选一项”,英语中的“ multiple choice ”是说“多项备选”,换句话说,就是汉语要“选择单项” 而英语里说“多选择项”.本质一样,名称着眼点不同. 既然“ multiple choice ”是“多项备选”,就不该存在“单项备选”的single choice了,一个选项备选,逻辑上没法讲. 正确答案不止一个 (more than one answer is correct) ”或要求“选出所有正确答案（ mark out all correct answers ）”

before hand 是马上的意思。人做主语要用C

11. B12.C13 A14 C15 D16 B 17 D18 C19 B20 A

小测零分的经验告诉我单项选择题是：multiple choice如果是多选题，会在后面加备注eg：1. balabalabal（不止一个正确选项）教授如是说……_(:з」∠)_至于不定项选择题，目前还未碰到这么狡诈的问法 — v —

he is taller than ___in his class A other anybody B anybody else -------------------------------other 后面跟复数 应该是 others 或者 other onesdon"t tell_____yourfriends" secrets A the other B others -----------------------the other 相当于一个定语 “其他的” 而且是特指的， 这句话 tell后面应该跟宾语，需要的是名词。others相当于 other ones 是正确的。

AB

AThefirsttime连接句子表示第一次，而Forthefirsttime只能在句子后面做补充成分，Atfirst只能在句子前使用，后面加逗号，Atthefirsttime则更不能连接句子故选A

D A B A B D A 翻译略捉急。。。。。求原谅，求采纳

"question"（问题）是英文中的单词，发音为 /u02c8kwu025bstu0283u0259n/。如果你想询问如何用英文表达"问题"这个词，那就是 "How do you say "问题" in English?" 或者简单地说 "How do you say "question" in English?"。当谈到"question"（问题）这个词时，它有几个常见的意义和相关的词组：1. 意义：- 问题：指一个需要回答或解决的事情、情况或观点。- 疑问：表示怀疑、不确定或需要进一步了解的事情。2. 相关词组：- Ask a question：提问，询问。- Answer a question：回答问题。- Questionnaire：问卷调查。- Question and answer：问答，问题和答案。- Question mark：问号，用于表示疑问或不确定。- Questioning：质疑，对某事提出疑问或怀疑。- Rhetorical question：修辞问句，用于强调说话者的观点而不是寻求答案的问句。- Leading question：引导性问题，试图影响回答者的问题。- Loaded question：含蓄问题，带有假设或暗示的问题，试图引导回答。- Open-ended question：开放性问题，没有固定答案的问题，鼓励回答者提供详细回答。- Multiple-choice question：多项选择题，提供多个选项供回答者选择。这些词组可以帮助你更好地理解和运用与"question"相关的概念和表达方式。如果你有任何进一步的问题，请随时提问！

中间的一段话named Chang"e after the story of a beautiful young girl who floated to the Moon，前后用逗号隔开了，这是作为从句来修饰programme，其实是省略了开头的which is，这样用named就容易理解了吧，如果不加逗号直接跟在programme后面就是做定语，那时才用naming。把中间的从句去掉，前后两段应该是一句话，所以用of来连接programme和missions。

B

such as to: "到如此程度以致" e.g.His illness is such as to cause anxiety.他病得很重,令人担忧。 The lecturer"s humor was such as to make every attendant burst into laughter.演讲者如此幽默，以致于每位听讲者都大笑不已！

1.A 2.A 3.D 4.A 5.D 6.C简单解析：1.如果使用比较级应为faster，fast不能加more2.are表示前面为复数，排除C；a lot不能直接接名词，要加of；much形容不可数名词，题目里的工程师和工人都是可数3.最高级修饰名词加the4.不知道哪件更好所以都拿了，用比较级better5.报告说后面的主语是size，所以选项修饰size，意思是家庭的规模越来越小，因此选D6.意思应该是好闻，排除BD，A选项和闻不搭配

1. Aas/though/although引导让步状语从句时，as引导的从句多用倒装，though很少见，although不能用倒装。再如：Child as he is, he knows a lot. = As he is a child, he knows a lot.2. A翻译：尽管我本（来）很想要借钱给他，但是我没那么做，因为我实在没有余钱。would have liked to是would have liked to lend him money的省略写法（后同），是would like to (do sth)的完成形式，意思是“本打算/想要做某事（实际上没做）”；BCD的结构都不符合语法搭配。3. C did he arrive还原成陈述句即可：He didn"t arrive at the sports ground until the game had begun.until从句使用了过去完成时，表明从句动作“运动会开始”发生在主句动作“他到达运动场”之前，即“过去的过去”。如果选A，则两句都使用过去完成时，那么过去完成时就失去了比较的标准了：过去完成时是指一个发生在另一个过去动作或时刻之前，即表明另一个动作的句子一般只能使用一般过去时。4. 正确答案为C，不是Bscarcely...when... = hardly...when... = no sooner...than... 一...就...其中前句用过去完成时且可倒装（即把过去完成时的助动词had提前到主语之前），后句不倒装且使用一般过去时。D错在时态，应该是：Scarcely had he arrivedB要改成：No sooner had he arrived (than) she started complaining如果对你有所帮助，请点

daaca其中第三题下面有位同学说是d，但我们老师给记了一句顺口溜：美小圆旧黄，法国木书房。讲的就是形容词顺序，可供参考，所以我认为三选a

C，准时到货永远不会过分，因为不能接受商品或服务会对客户造成严重不良影响，大概就是这个

我可以回答有些是固定搭配，有些是纯属单词理解的问题么？觉得你可以适当的增加单词量，这样做题时就很好区分哪些是正确答案了

A，因为定语从句作主语；B，把从句还原成肯定句就是you believe who is not about to support our plan .
