新概念英语第二册：第21课课文详解及语法解析
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 textlive 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。
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。

新概念英语第二册课后习题答案详解Lesson 21
新概念英语第二册课后习题答案详解Lesson 11. 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 front of 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。
新概念英语第二册第21课习题答案
新概念英语第二册第21课习题答案1. d根据课文第4-5行She threw the bottle into the sea. She never thought of it again, 只有d. She didn’t expect anyoneto 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) 能够同介词of 或about连用，也能够跟that引导的从句做宾语，但不能跟动词不定式。
a. toreceive 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，能够做dreamed 的宾语，所以应该选d.4. d只有d. the same age as(与……年龄相同)之处是准确的表达方式；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, 不准确；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，所以只有b. throw 是准确答案。
6. d只有d. about才能同thought构成短语动词表示“考虑”其他3个都不是准确的表达方式。

新概念英语第二册课后题答案详解：Lesson21
新概念英语第二册课后题答案详解：Lesson21 1. c依据课文第3-4行Last year, however, it came into use, 只有c. came into use recently 比拟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依据课文第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 的含义一样，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(不行能的)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想。
b. I’m sure(我确信) 语气比拟确定，不表示推想;c. Certain(确定的)是形容词，缺主语和谓语，不符合语法和题目意思。
; d. Of course(固然) 表示“确定”的意思，也不够精确; 只有a. I think(我想，我认为) 表示推想，所以应当选a.6. c只有c. are some left 才能使这个句子比拟接近前一句I am one of the few people left,由于few(少数几个)同some(一些)意思比拟接近, 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(剩下许多)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。

新概念英语第二册课后题答案详解：Lesson21
新概念英语第二册课后习题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，仅仅语态不同。
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，所以选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，能够修饰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 的含义有些差别;c. may (能够) 词意思更不准确。
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，所以应该选c.
12. c
只有c. correct(对的，准确的)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。
