第二节 情景交际 通读下面的对话,根据上下文补全对话内容。(共5小题,计10分)

A:Jeff, 71 ?

B:Yes, Mum. I finished my homework a few minutes ago.

A:But what are you doing now?

B: 72 . I just want to relax myself.

A:Is that also your homework?

B:Not really. But the video is well worth watching, I suppose.

A:You do? 73 ?

B:It's about the Belt and Road(“一带一路”). 74 ?

A:Yes, I've just heard something about that on the radio. Anyway, it may be a little bit hard for you to understand.

B:A little bit hard? You must be joking. In the video, the conversation between the father and the daughter explains the topic lively and clearly.

A:It does? Can I watch it with you?

B: 75 . I promise you'll find it amazing and interesting.

答案解析：

71.根据答语“Yes, Mum. I finished my homework a few minutes ago.”(是的，妈妈。我几分钟前就完成了作业。)可知，问句是在询问对方是否完成了作业。含有实义动词的过去时的一般疑问句结构是“Did + 主语 + 动词原形 + 其他?”，主语是“you”，所以用“Did you finished your homework”。

72.上文问“But what are you doing now?”(但是你现在在做什么?)，下文提到“But the video is well worth watching, I suppose.”(但我想这个视频很值得一看。)，由此可知，此处应回答正在看视频，现在进行时的结构是“be + 动词的现在分词”，主语是“I”，所以用“I'm watching a video”。

73.根据答语“It's about the Belt and Road(‘一带一路’).”(它是关于“一带一路”的。)可知，问句是在询问视频是关于什么的。“What's...about?”是询问“……是关于什么的?”的常用句型，所以此处填“What's it about”。

74.根据答语“Yes, I've just heard something about that on the radio.”(是的，我刚在收音机里听到了一些关于它的消息。)可知，问句是在询问对方是否听说过“一带一路”。“hear about”表示“听说”，现在完成时的一般疑问句结构是“Have/Has + 主语 + 过去分词 + 其他?”，主语是“you”，所以用“Have you heard anything about that”。

75.上文问“Can I watch it with you?”(我能和你一起看吗?)，下文说“I promise you'll find it amazing and interesting.”(我保证你会发现它既神奇又有趣。)，由此可知，此处是同意对方一起看视频，“Sure”或“Of course”都可以表示“当然可以”，符合语境。
