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。

How did William Hart's childhood prepare him for his acting role in Western films?William S. hart was, perhaps, the greatest of all Western stars, for unlike Gary Cooper and John Wayne he appeared in nothing but Westerns. From 1914 to 1924 he was supreme and unchallenged. It was Hart who created the basic formula of the Western film, and devised the protagonist he played in every film he made, the good-bad man, the accidental-noble outlaw, or the honest-but-framed cowboy, or the sheriff made suspect by vicious gossip; in short, the individual in conflict with himself and his frontier environment.Unlike most of his contemporaries in Hollywood, Hart actually knew something of the old West. He had lived in it as a child when it was already disappearing, and his hero was firmly rooted in his memories and experiences, and in both the history and the mythology of the vanished frontier. And although no period or place in American history has been more absurdly romanticized, myth and reality did join hands in at least one arena, the conflict between the individual and encroaching civilization.Men accustomed to struggling for survival against the elements and Indians were bewildered by politicians, bankers and businessmen, and unhorsed by fences, laws and alien taboos.Hart's good-bad man was always an outsider, always one of the disinherited, and if he found it necessary to shoot a sheriff or rob a bank along the way, his early audiences found it easy to understand and forgive, especially when it was Hart who, in the end, overcame the attacking Indians.Audiences in the second decade of the twentieth century found it pleasant to escape to a time when life, though hard, was relatively simple. We still do; living in a world in which undeclared aggression, war, hypocrisy, chicanery, anarchy and impending immolation are part of our daily lives, we all want a code to live by.【参考译文】威廉.S.哈特大概是美国西部电影明星中的佼佼者。
