①你觉得我们什么时候见面好？

_______________________________________________________________________________

②我想他们马上就到。

Keys: ①when do you think is convenient for us to have a meeting?

　　　②I believe they will arrive shortly.

(2) This is similar to the "jet lag" you get when flying,...这与你在飞行过程中的时差反应是相类似的。

【句法分析】When flying是when you are flying的省略形式。在有些表时间、条件、方式或让步的从句中，如果谓语包含有动词be，主语又和主句的主语一致，或者主语是it，就常常可以把从句中的主语和be动词省略。

【典型例句】

① When asked where the toilet is, the waitress showed the way politely to the guest.

当被问及厕所在哪时，服务员非常有礼貌地给客人带路。

② Until finishing the homework, the child was allowed to watch the cartoon film.

直至完成作业，小孩才允许看卡通片。

③ If necessary, you can call help from the police.有必要时，你可以求助警察局。
