3.多项选择题答案
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 girl, 只有d. She istoo 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 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 oldJennifer 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 done 都不符合题目意思.
  7. bbe necessary for sb. to do sth. 等于 sb. must/have to do sth., 只有 b.
  necessary 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 presented 有参加演出的意思,只有选a. is presented 才能使这句话同前一句She oftenappears as a young girl(她常扮演小姑娘)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. won't be in 与题目意思相反。只有c. will be in 最符合题目意思。
