【解析】

本题主要通过句子来巩固已经学过的句式，因此，完成句子时需要领会题目要求，进而结合学过的句式结构进行仿写。

1.考查not until的倒装结构。其句式结构为：Not until +时间状语（从句）+助动词+动词+主语+其它。完成句子时该结构中的时间状语（从句）为原陈述句中until后的内容，原句在完成的时候主句要用肯定形式。故写成：Not until the underground treasure was unearthed did the local people know the secret.

2.考查虚拟语气句式：It + be +requested + that+ 其它。结合本句，that之后直接跟上原句that后的内容即完成了要求。故写成：It was requested that a return ticket（should）be booked right away.

3.考查近义短语替换。根据题目要求，直接替换即可。故写成：What should we take into consideration before we decide to travel abroad？

4.考查非限制性定语从句。定语从句的构成：先行词 + 关系词 + 从句，关系词在用法上既指代先行词又在从句中作成分，同时连接先行词和从句。根据这点，完成句子时，先找出先行词，根据其在从句中的成分进而选择关系词。结合给出的两个句子，共同提到了families,所以选定其为先行词，进而根据两个句子所讲内容，选定第二个分句为从句，该句子中in the families作状语，所以可以使用where或 in which来引导定语从句，所以可以完成句子。故写成：Living with host families，in which /where there may be other college students，gives them the chance to learn more about the new culture.

5.考查It作为形式主语的句式：It is/was the first time （that），使用该句式时，that从句要用完成时,当主句是is时，从句用现在完成时；若是was时，从句用过去完成时。由给出的句子看，用的是一般过去时，所以that从句要用过去完成时。故写成：It was the first time that I had come to live and study in a completely strange city.

6.考查同义词替换。instead of“代替，而不是”，根据其意思，可知使用时要替换原句中but not, 同时使用时of后的动词用V-ing形式。故写成：Instead of saying something meaningless， it is more mean-ingful to try getting around the world.
