New words and expressions 生词和短语
Appear
v. 登场，扮演
① vi. 出现，显露（反义词为disappear）
The plane appeared. / The plane disappeared. I can’t appear in this dress at the party. Appear as: 扮演…角色 Appear on the stage as : 在舞台上扮演…
新概念英语第二册课后题答案详解Lesson17
新概念英语第二册课后题答案详解Lesson171. d根据课文第1-2行She must be at least thirty-five years old. In spite of this , she often appears on the stage as a young girl, 只有d. She is too old to appear on a stage as a young girl 是课文所暗示的情况，而其他3个选择都与课文内容不符。
2. b课文第1行有She must be at least thirty-five years old(她至少也有35岁了)，这仅仅个推测，并没有告诉读者她的确切年龄有多大，所以a. We know exactly how old Jennifer is 与课文内容不符;c. Jennifer is thirty-five years old 也与课文内容不符，因为课文中没有明确较大她确切的年龄是35岁;d. Jennifer is over thirty-five years old 也不够准确，因为作者推测她至少有35岁，可能超过35岁，也可能正好35岁;只有b. We do not know exactly how old Jennifer is 是准确的。
3. b这个句子是对前一句作出肯定的陈述，只有b. is 才是最合乎题目意思和语法的：In my opinion she is (at least thirty-five years old.) 而 a. has 后面不能跟年龄，所以不符合语法;c. can是情态助动词，意思是“能，能够”，不符合题目意思;d. must 是情态助动词，能够用来表示推测，但在后一句话中应明确表示个人的看法，而不是众人的推断，所以b是准确答案。
4. d从后一句的回答中能够看出，前一个疑问句应针对年龄提问，所以只有d. How old 是准确答案。

1. d根据课文第1-2 行She must be at least thirty-five years old. In spite ofthis , she often appears on the stage as a young gi只有d. She istoo old to appear on a stage as a young gir是课文所暗示的情况，而其他3个选择都与课文内容不符。
2. b课文第1 行有She must be at least thirty-five yearsold她至少也有35 岁了)，这只是个推测，并没有告诉读者她的确切年龄有多大，因此 a. We know exactly how oldJe nnifer is 与课文内容不符；c. Jennifer is thirty-five years old 也与
课文内容不符，因为课文中没有明确较大她确切的年龄是35岁；d. Jennifer is over thirty-fiveyears old也不够准确，因为作者推测她至少有35岁，可能超过35 岁，也可能正好35 岁；只有 b. We do not knowexactly how old Jennifer is是正确的。
3. b这个句子是对前一句作出肯定的陈述，只有 b. is才是最合乎题目意思
和语法的：In my opinion she is （atleast thirty-five years old.）而 a. has后面不能跟年龄，因此不符合语法；c. can是情态助动词，意思是“能，可以”，不符合题目意思；d. must是情态助动词，可以用来表示推测，但在后一句话中应明确表示个人的看法，而不是众人的推断，所以b是正确答案。
4. d从后一句的回答中可以看出，前一个疑问句应针对年龄提问，因此只
有d. How old是正确答案。
5. c介词in有时可以用来表示穿什么服装或穿什么颜色的衣服，这句话只
有c. in意思才正确。
其他3个都不符合语法。
6. c只有c. has to do与前一句的must意思相同又符合第3人称单数she的
要求.因此只有选c. has to do.而b.
have to do不能用于第3人称单数，a. has done , d. had don都不符合题目意思.
7. bbe n ecessary for sb. to do sth等于sb. must/have to do sth.只有b.
n ecessary才能使这一句同前一句的意思相同，而其他3个选择都不符合题
目意思。
8. aa. is prese nted有参加演出的意思，只有选a. is prese ntec才能使这句话同
前一句She often appears as a you ng gi哋常扮演小姑娘）的意思相吻合。
而b. points （指出，）词意思不符。
c. shows展示，表现）常做及物动词
d. seems似乎是，好像）词意思不对。
因此a.是正确答案。
9. ab. game游戏，比赛）,c. toy（玩具）,d. match（比赛）这3个都不符合题目意思，只有a.
play（剧本,戏剧）符合题目意思.
10. c前面的句子Jennifer will take part in the play 的意思是“Jennifer要参加这
个剧的演出”而不是参与写作或创作这个剧本，因此不能选 a. will write和d. willproduce,而b. wo n't be in与题目意思相反。
只有c. will be in最符合题目意思。
11. asocks为男女用短袜，stocki ng为女用长筒袜。
只有a. socks in stead of stock ings最符合生活常识，而其他3个选择都不对。
12. d只有d. an adult（成年人）才能与前一句中的grow up（长大，成人，成熟）意思相符合，而其他3个选择a. veryold（很艮老），b. an adolesce nt青少年），c. teen ager（13岁到19岁的青少年）意思都不够准确。
