新概念英语第二册第二十一课课后习题答案详解
Lesson 21
1. c根据课文第3-4行Last year, however, it came into use, 只有c. came into use recently 比较接近课文的实际内容，而其他3个选择都不符课文内容。
2. d根据课文第8行…but I am determined to stay here, 只有d. has refused to leave his house 与课文内容相符，其他3个选择都与事实不符。
3. c只有选c. can hear 才能使这个句子同前一句Passing planes can be heard night and day 的含义相同，只是语态不同。而其他3个选择a. can heard, b. can to hear, d. can be heard 都不符合语法，在意思上都讲不通。
4. d 只有d. possible 才能使句子同前一句It couldn't be used then 意思最接近。a. able (能)需要人作主语，本句的主语是it 形式主语;b. allowed(允许)不符合题目的意思，c. impossible(不可能的)与句子意思相反。
5. a 前面句子Over a hundred people must have been driven away 中的must 表示说话人的一种主观推测。b. I’m sure(我确信) 语气比较肯定，不表示推测;c. Certain(肯定的)是形容词，缺主语和谓语，不符合语法和题目意思。; d. Of course(当然) 表示“肯定”的意思，也不够准确; 只有a. I think(我想，我认为) 表示推测，所以应该选a.
6. c 只有c. are some left 才能使这个句子比较接近前一句I am one of the few people left,因为few(少数几个)同some(一些)意思比较接近, a. are none left(一个没剩)不等于the few.b. is one left(剩下一个)也不等于the few;d. are a lot left(剩下很多)与the few 意思相差悬殊.所以选c.
7. b 这是一个疑问句，需要主谓倒置语序。a. have you been offered, C. you have offered, d. they offered you 这三个选择都是陈述句语序，只有b. have you been offered 是疑问句语序，因此选b.
8. b 只有b. give(给)出同前面的动词offered 词意思相近，而a. serve(服务，服侍)，c. take(拿，带)，d. make(做，制造) 这3个选择都与offered 意思不同。
9. a b. number 只能修饰人，不能修饰不可数名词money, c. some不符合语法，意思不成立; d. piece 只能修饰不可数名词，但是不能修饰money.只有a. amount(很多，一大笔)表示金额，可以修饰money.a large amount of很多，一大笔,表示金额，a number of是只用于可数名词
10. d 只有d. am going to 才比较接近前一句I am determined to stay here.(我决定留在这里)的含义。其他3个选择中：a. am will to 不符合语法; b. want to(想要)与be determined to 的含义有些差距;c. may (可以) 词意思更不正确。
11. c 只有c. Perhaps 才能与前一句中的…they are probably right(……他们可能是对的)意思相吻合，表示“可能”，“也许”(不肯定的推测)，而a. Of course(当然)，b. It’s certain( 肯定)，d. It’s sure(一定) 这3个选择都带有肯定的意思，因此应该选c.
12. c只有c. correct(对的，正确的)这个句子才通顺，而a. just(公正的)，
b. fair(公平的)与d. equal(平等的，相等的)这3个选择都不符合题目的意思，所以选c

新概念英语第二册课后习题答案详解
Lesson 1 1. b选b最为正确。因为a. d.都与课文内容不符合，也不合乎逻辑；c?的意思是“他们没有注意他”，而作者的意图 并不是想让他们注意他，而是想让他们停止谈话。 所以选 b. 最能表达作者当时心里的感受。 2．c 其余3 个答案都与原句意思不符合。 3．b 因为a. to 不对，可以是He went to the theatre;c. into 也不对，可以是He went into the theatre;d. on 更不符合语法，表示在某一个地方用介词in 或at, in 表示在大的空间，如国家，城市等，at则表示在小的地点或空间，如atthe office, at the theatre 等,所以选b.是正确的。 4. ............................ db. above（在.......... 上方）；c. ahead of （在的前面，在之前）不和behind对应， 也不强调位置的前后顺序。 a. before和d. infront of 都是和behind对应的，都有“在........ 前面”的意思。但in frontof更具体的强调位置，而before则包含更宽泛的意思，即时间上， 空间，次序，登记，重要性方面的“在……前面” 5. c 因为用a. Where, b. why, d. when 提问都不符合逻辑，都不是针对状态提问的，只有How 提问，才能用Angry 回答。 6. ab. they 只做主语；c. their 只能做定语；d. us 虽然可以做宾语，但与前一句意思不符合。 7. da. none 是代词，很少用在名词前面； b. any 只能用在否定句或疑问句中； c. not any 不符合语法，因为前面没有助动词did. 8. ba. chair（椅子）,c. armchair（手扶椅）d. class（班级）这3个选择都和seat的意思不符合。Seat是”座位，座席”的意思。强调的是可供坐下的地方，不是具体的椅子。只有b. place 是seat 的同义词。 9. ab. big（大的）指体积；c. tall（高的）指身材；d. large（大的）指空间和面积。 这 3 个词都与人的年龄无关。只有 a. old 是说明年龄的。 10. ca. sad（悲哀，忧愁的）没有生气的意思；b. unhappy（不幸的，不快乐的）不一定是生气；d. pleased（高兴的）同angry意思相反；只有 c. cross（脾气坏的，易怒的，生气的）与angry 意思相反。 11. cc. stand是bear的同义词，都有忍受的意思。而其他3个选择都没有忍受的意思。 12. ca. clever（聪明的）,b. rude（粗鲁的）,d. kind（仁慈的）这3个都不是rude的反义词， 只有polite（有礼貌的）才是和rude 相对应的反义词，所以选 c. Lesson 2 1. c因为根据课文内容，作者正在吃早饭，他不可能在床上。所以a. 和b.与课文内容不符合，作者强调尽管他起床很晚，已经是中午，但他还在吃早饭，所 以 d. 也不对。 2. d因为只有d.才是Aunt Lucy感到惊讶的原因，其他3个选择都不合乎逻辑。 3. c本句有一个表示经常性动作的时间状语sometimes,所以要用一般现在时。因为主 语是He, 所以它后面的动词要在词尾加s. a. stay 词尾没有加s; b. is staying 是进行时；d. staying 是现在分词；只有 c. stays符合时态和人称。 4. cgo to bed 是固定词组，意思是“就寝” 。 a. in 可以用在stay in bed 之中； b. into 和 d. at 不符合语法和习惯用法，英语中不用into bed, at bed 这样的短语。

新概念英语第二册：第21课课文详解及语法解析课文详注 Further notes on the text 1.I live near an airport and passing planes can be heard night and day. 我住在一个机场附近，过往飞机日夜不绝于耳。 (1)passing 是现在分词，作形容词用，表示“经过的”、“过往的”：He stopped a passing car. 他挡住了一辆过往汽车。 He forgot the man with passing time. 随着时间的消逝，他忘掉了那个人。 (2)night and day是固定短语，意为“日日夜夜”、“夜以继日”：He thought of the matter night and day. 他日夜在想这个问题。 He worked night and day. 他夜以继日地工作。 2.The airport was built years ago, but for some reason it could not be used then. 机场是很多年前建的，但因为某种原因当时未能启用。 (1)years 前面不加确定的数词时，一般表示“很多年”，weeks 等的用法与它相似： He left the city years ago. 他多年前就离开了这座城市。 I have not seen him for weeks.
我已经有好几个星期没见他了。 (2)some 在这里不表示“一些”，而表示“某个”、“某种”等： I'll tell you someday. 有一天我会告诉你的。 We'll talk about it some other time. 我们改日再谈这件事。 3.…it came into use. ……机场开始使用了。 come into use 为固定短语，表示“开始被使用”： When did the train come into use? 这火车什么时候开始使用的?

He must have been here. 这枝钢笔是约翰的。他一定来过这里。 5.I am one of the few people left. 我是少数留下来的人中 的一个。 (1)one of表示特指的一群人/一些东西中的一个，后面的名词用复数：

I can't put up with him any longer. 多项选择题讲解 1. 选（d）。 根据课文第5～6行But some time later it began to rain. The boys felt tired so they put out the fire and crept into their tent… 只有（d）it had begun to rain and they felt tired才是孩子们去睡觉的原因。（a）it was late是事实，但不是他们睡觉的直接原因；（b）they had sung songs不符合逻辑；（c）it began to rain 只是一方面原因，但不够完整。 2. 选（c）。 根据课文后两行The stream wound its way across the field and then flowed right under the tent! 只有（c）had camped in the path of a stream（在一条小溪穿过的地方露营）与课文实际情况相符，其它三个选择（a）had a good night's sleep（睡了一晚上好觉）、（b）stayed in their tent all night（整晚呆在他们的帐篷里）、（d）had camped beside a stream（在一条小溪旁露营）都与事实不符。 3. 选（d）。 （a）it put up和（b）their tent put up语序错误，宾语应该放在谓语动词的后面；（c）put up it也不正确，当宾语是代词时应该放在动词和副词之间；只有（d）put their tent up语序正确，宾语tent是名词，既可以放动词和副词之间，也可以放副词之后，所以要选（d）。 4. 选（d）。 （a）As soon不能引导状语从句，因为后面缺少as； （b）Just as（正当）可以引导从句，但它强调两件事情同时发生，而这个句子是表示两件事一前一后发生；（c）Until（直到……为止）词义不对；只有（d）Just after（刚刚……之后）时间正确，也符合语法。 5. 选（d）。 （a）they had hunger不符合英语习惯；（b）they had hungry语法错误，hungry是形容词，它前面应该是连系动词be，而不是had；（c）they were hunger也不符合语法，连系动词were后面应跟形容词，不能跟名词hunger；只有（d）they felt hungry是正确的，动词fell后面既可以跟形容词hungry，也可以跟名词hunger。 6. 选（b）。 只有选（b）near（在……旁）才能同前一句中的by the campfire（在篝火旁）意思相同；（a）close 是形容词，后面要加上介词to；（c）besides是介词，但表示“除……之外”，词义不对；（d）at（在……）没有“在……旁”的意思。 7. 选（a）。 本句是一般过去时的疑问句，需要选正确的谓语动词。只有选（a）flow是正确的；（b）flowed是过去式，在疑问句中已经用助动词did提问了，就不应该再用过去式了；（c）flew是fly（飞）的过去式，时态和词义都不对；（d）fly词义不正确。 8. 选（d）。 （a）sing songs（唱歌）、（b）tell stories（讲故事）、（c）play（玩）这三个选择都不能同前面的They cooked a meal构成因果关系，因此不符合逻辑；只有（d）eat（吃）才是They cooked a meal的原因，所以是正确答案。 9. 选（d）。 本句是对前一句The boys had put out the campfire （孩子们扑灭了篝火）的解释说明。（a）switched on （打开电源开关）不符合题义：（b）on fire（着火）意思不通；（c）on（打开的）指电源而不是指火，be动词和on连在一起还有“上演”的意思；三者都不对。只有（d）alight（着火的，照亮的）是表语形容词，在这里作表语，并同前一句意思相同，是正确的。 10. 选（c）。 只有选（c）were very quiet（很安静）才与前面的They crept into their tent（他们钻进帐篷）的意思相符，因为creep有“蹑手蹑脚”的含义。而（a）made a lot of noise（制造很多噪音）、（b）ran quidkly（快 跑）、（d）were very noisy（非常吵闹）这三个选择都不符合creep的含义。 11. 选（c）。 只有（c）comfortable（舒适的）最符合句子的要求，因为连系动词were后面应该跟形容词作表语，说明sleeping bags的状况。（a）a comfort是名词、（b）in comfort是介词短语、（d）comfortably是副词，词性都不对。 12. 选（c）。 只有（c）deeply（深深地）修饰sleep才与前一句的soundly（香甜地）意思相近；而（a）noisily（吵闹地）、（b）fast（快）都不符合题义；（d）good（好的）是形容词，不能修饰动词sleep。 1

She didn’t expect anyone to find the bottle 是课文所暗示的内容，其他3个选择都不符合课文实际内容。 2. b 根据课文第6行Both girls write to each other regularly now, 只有b. correspond in the normal way now 与课文实际内容相符合，correspond=write to each other, 其他3个选择都不是课文提及的内容。 3. d 本句中的动词dreamed(梦想) 可以同介词of 或about连用，也可以跟that引导的从句做宾语，但不能跟动词不定式。a. to receive 是动词不定式，不合乎语法；b. to receiving 有语法错误，应该是dream of receiving; c. of receive 有语法错误，应该是of receiving; d. that she would receive 是that 引导的从句，可以做dreamed 的宾语，因此应该选d. 4. d 只有d. the same age as(与……年龄相同)之处是正确的表达方式；而a. the same age with 不符合语法，same 不应该同with 连用，而应该同as连用；b. the same age 后面缺as, 不正确；c. as old 后面也应该有as 才符合语法。 5. b 这个句子是一般过去时形式的疑问句，所以填的动词应该是动词原形，因此只有b. throw 是正确答案。 6. d 只有d. about才能同thought构成短语动词表示“考虑”其他3个都不是正确的表达方式。 7. a 只有a. to one another(互相)最符合语法和习惯用法。 b. the one to the other 虽然语法上讲得通，但意思古够通顺； c. each to other不符合语法，应该是to each other; d. to other 不符合语法。 8. c 只有c. trip(旅行) 是正确的表达方式，与前面的were traveling 的意思相符。 a. sail(航行) 不合乎题目意思；b. travel 不是正确表达方式，可以是went on a journey/trip; d. run(跑) 不是正确的表达方式，也不合乎题目意思。 9. d 只有d. sheet (张) 是正确的表达方式，而其他3个选择a. lump(块，团)，b. bar(条，

Don't leave your car here 同它意思接近。 其他3个选择意思都不够贴切。 b. without parking 没有停车 c. don't stop 别停下来 d. There's no room to park her e. 这里没有停车的地方了。显然跟“禁止停车”意思相差悬殊。 7. d为了说明前一句This note is only a reminder(这张字条只是一个提醒.)的强调语气词only只是,仅仅是.只有选d. nothing more 意思最接近,其他3个选择意思都不对. a. nothing 什么也没有 b. no one 没人 c. nothing extra 没有多余的 d. nothing more 只是, 再没有了. 8. a只有a. district(区)与此同时前一句的area(地区)意思最接近. 而b. country(国家,乡村),c. surrounding(周围环境),d. kingdom(王国)这3个都同area意思不同. 9. d本句需要对前一句you will enjoy your stay(你会过得很快乐)作进一步解释。
