Passage A

Dear editor，Why do newspapers have so many advertisements for electronic(电子的)equipment? Last Sunday I counted ads.for seven kinds of televisions and thirteen kinds of radios in the Youth Journal.Besides that, there were pages and pages of ads.for Citizens’ Band radios and tape recorders.Don’t you realize what electronic equipment is doing to our daily life? Everywhere you go you may hear loud music and advertisements over radios;this continuous noise is doing harm to our ears.Husbands don’t talk to wives any more;they are always watching the news or a ball game.Children’s eyes become hurt with endless hours of watching not only the programs for children but also those for grown-ups as well.And worse, hidden microphones find out our personal lives, and computers keep records of personal information about us.That is enough!I think you should limit the amount of advertising of electronic equipment in the Youth Journal, or it will make life unbearable(难以忍受的)for us all.1.Youth Journal is the name of _________..A.a department star B.a shop that sells electronic equipment

1.c 根据课文第1-2行可以推断，只有c.it wasn’t flying in the right direction 才是飞机坠毁的原因，所以只有c.是正确答案。其他3个选择都不能说明飞机坠毁的原因。2.a 根据课文第11行a pilot saw the signal and sent a message 可以推测，只有a 是课文所暗示的内容，其他3个选择都与课文的内容不符。3.b 只有选b.young 才能使该句同前一句意思相同.若选a.a youth 同前一句意思不符;c.a young 不合乎语法;d.youth 既不符合语法也不合乎题目意思.4.d 此句是一般过去时疑问句。因为有助动词did 提问，所以句子的谓语动词要用原形。a.lay 是动词原形，词意思为“使……躺下，放置”，它也是动词lie 的过去式；b.laid 是 lay 的过去式和过去分词形式；c.lain 是动词lie 的过去分词；d.lie 是动词原形，意思为“平放着，处于某种状态”；只有lie 最符合语法和题目意思，所以选d.5.b 只有选b.big enough 才能使本句与前一句It was too small 意思吻合。而 a.enough big 词序不对，不合乎习惯用法，c.fairly big(相当大)，d.rather big(相当大)，他们都很少用于否定句中。6.a 该句的谓语动词hear后面应该跟名词+不带to 的动词不定式，或跟名词+动词+-ing，只有a.pass 是不带to的不定式最符合语法，其它3个选择都不符合语法，所以选a.7.b 只有b.soon afterwards(不久，很快)与前一句中的not long before 的含义相同，其他3个选择a.after(在……之后)；c.behind(在……后面)；d.much later(更晚)都不符合题目意思，所以选b.8.b 该句需要选出一个与前一句的light(轻型的)意思相反的词.a.dark(黑暗的), b.heavy(重的), c.black(黑的), d.deep(深的)4个词中只有heavy是light的反义词,所以选b.9.d 该句应该选前一句的terribly(可怕地，极端地)含义相近的形容词。才能使两个句子意义相同。a.frightening(使惊恐，恐吓)是动词frighten的现在分词形式，很少作形容词用，因为它的形容词形式是frightful;b.horrifying(使毛骨竦然，使震惊)也很少做形容词用，因为它有形容词horrible;c.shocking(令人震惊的，骇人的，极坏的)语气比terrible 要强烈；d.frightful(惊人的，可怕的)是动词frighten的形容词形式，只有d与terribly 含义最接近，所以选d.10.d 本句需要选一个与前一句中的signal(信号)含义相同的词。

新概念英语二册测试卷 篇4

根据课文的实际内容，可以推断只有b.had found Sam’s wallet and kept it 是课文暗示的真实情况。a.had stolen Sam’s wallet 不够确切，因为课文中的意思是Sam was sure that the wallet must have been found by one of the villagers(山姆确信那钱包是被某个村民捡到了，而不是偷走了);c.had lost Sam’s wallet 与课文的意思相反;d.had taken the wallet from Sam’s pocket 不是课文提及的内容。

2.d

根据课文所描述的情况，只有d.returned all the money 与课文事实相符，其他3个选择都与事实不符。

3.a

a.when, b.while, c.as 和 d.just as 都可以做连词，引导时间从句，表示“当„„时”，本句只能选a.在前半句是过去进行时，后半句是一般过去时的情况下，中间多用when，表示两个动作同时发生，“正当„„时”，而后3个选择引导的时间从句大都是进行时态。

4.b

本句只有选b.in 意思才讲得通。He keeps his savings in the post office.(他把存款放在邮局保管)。本句中的动词keep(存放，保管)不是表示“去向”的，所以不能选a.to(到)和d.into(进入)，c.on(在„„上面)也不合乎题目意思，不能用on the post office.而应该是in the post office.(在邮局里)，所以选b.5.b

本句是一个被动语态句。只有b.by 表示“被”的意思，最符合语法和题目意思。a.from , c.out of, d.of 都没有“被”的意思，所以都不对。

6.d

本句是一个特殊疑问句，针对介词in的宾语提问的，回答是A newspaper.a.where 是询问地点的;b.who 是针对主语(人)提问的;c.how 是询问状态的。这3个选择都不对。只有d.What 是对物提问的，所以选d.7.c

前一句是被动语态Some more money was sent to Sam, 后一句又换了一种说法，将原句中的间接宾语Sam变成主语，原句中的Some more money 变成了宾语，还应该用被动语态才能使两个句子意义相同。a.sent 是主动语态过去时;b.has sent 是完成时主动语态;d.had sent 是过去完成时主动语态。这3个选择都不是被动语态，因此都不对。只有c.was sent 是过去时被动语态，符合语法和题目意思，所以选c.8.b

a.coins(硬币)，b.notes(纸币，钞票)，c.cheques(支票)，d.photographs(照片)。4个选择中只有b.notes最符合题目意思，因为本句中的wallet(夹子，钱夹)是用来放钱(钞票)的，所以选b.词意思最贴切。

9.c

a.would 是wind 的过去式，意思是“缠绕，卷” b.rolled(卷，滚);c.wrapped(包裹);d.bound(绑，缚)。从词的搭配上来讲，只有c.wrapped 词意思最贴切，最适合这个句子，其他3个选择都不符合题目意思，所以应该选c.10.b

本句需要选一个同前一句的did it contain意义相同的短语。

a.did it consist 不合乎语法，也不合乎题目意思，consist 后面应该有of,表示“由„„组成”;

c.did it include(它包括);

d.had it(它有)，这3个选择都不够贴切，只有b.was there in it(里面有)最接近did it contain的含义，所以选b.11.d

a.money(钱)，b.a coin(硬币)，c.a cheque(支票)和d.a message(口头或书面的消息，口信，便条)这4个选择中只有d与前一句中的note(字条)意义相近，所以选d.12.b
