12、.will beLesson 17 （课下作业）参考答案I. 1.B 主语是物，因此要用cost。2.A 本题考查定语从句。先行词是表示人的词，且连接词在从句中作主语，故用who。3.C either和both可以用于表示两者，由谓语动词are可知，主语为复数，either of作主语表示单数，both of作主语相当于复数，故选C。4.A 情态动词must 的否定回答常有neednt,又根据答语中的后一句，可知选A。5.B 由上半句可以推出下半句是劝“不必担心”。cant不能；neednt不必；mustnt禁止；couldnt不能，故选B。6.C teachers是谓语动词的承受者，因此本句
13、用被动语态，故选C。7.C 动词want 后面必须加动词不定式做宾语，故选C。8.B 根据题意是“为什么不在报纸上做广告”，故选B。II. 1.isnt he 2.may know 3.dont need any 4.The bag cost 5.Whats the price ofIII. 1.D。答案就在短文首句的“ The sun is a huge, hot, bright star.”之中，其中包含的三个形容词正是本题的答案。2.A.短文首段末句和第二段的首句“The sun gives us light and heat. All living things need light
14、and heat from the sun to live.”是解答该题目的重要依据。3.C.本小题属于表层理解题。答案显然在“If there was no sun，it would be dark all the time. Even when the sky is cloudy, the sunlight is very strong and it shines through the clouds.”一句中。4.B.本小题同样属于表层理解题。“All the food we eat comes from plants in a food chain(链)which starts with the sun.”这句话是问题的出处。此句是定语从句，要仔细阅读才能正确理解。5.C.根据“It is important because without it there would be no life on Earth.”和“If there was no sun, it would be dark all the time.”这两句话，可很容易将其余三个选项排除。3
