v 重点句子 （旨在提供句子结构等所需材料）
1.what problems do you think people in the future will have overcome?
你认为未来的人们将克服什么问题?
[解释] 此句为复杂疑问句，其句式结构为：疑问词+do you think+其余部分(其余部分为陈述语序),do you think 为插入成分。能用于此句型的动词有：think，believe，suppose，imagine，suggest，expect等。
[典例]
1)who do you think is the tallest in your class?你认为在你们班谁最高?
2)what do you believe matters when we take up the work?你认为我们从事这项工作什么东西最要紧?
3)who do you suppose will win the game?你认为谁会赢得这比赛?
[注意]
1)如果此句型的动词后面的从句里有否定意义，往往要把否定前置。如：
i don't think it’s right to do so.我想这样做是不对的。
2)该句型变反意疑问句，主句主语是第一人称且是现在时态时，反问部分与从句一致，否则与主句一致。如:
i think that he has been to beijing，hasn't he?
he thinks that their team are sure to win the game，doesn't he?
[练习] 汉译英

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。
[解释] 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。
[典例]
1) when asked where’s the toilet, 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。
