解析　本题考查同位语从句。空格后的句子结构完整，不缺任何成分，所以用that引导，起连接作用。

11．Please remind me ________ he said he was going.I may be in time to see him off.

A．where B．when

C．how D．what

答案　B

解析　when引导宾语从句，在从句中作时间状语，意为"当......的时候"。根据所提供的情景"I may be in time to see him off."可判断出说话人请求对方提醒的是走的时间。在这个句子中，he said是插入语。where引导宾语从句表示"在......地方"。how引导宾语从句表示"如何"。what在宾语从句中作主语、宾语或表语。

12．________ makes this shop different is that it offers more personal services.

A．What B．Who

C．Whatever D．Whoever

答案　A

解析　what引导主语从句，在从句中作主语。句意为：这个商店提供更多的个性化服务使得它与众不同。who谁；whatever无论什么；whoever无论谁。

13．These wild flowers are so special I would do ________ I can to save them.

C．which D．whichever

答案　A

解析　do后接宾语从句，宾语从句I can后省略了do，缺少宾语。whatever在宾语从句中作宾语。

14．We have come to the conclusion ________ the company has been making great progress these months.

答案　B

解析　句意为：我们已得出结论：公司这几个月取得了巨大的进步。that引导同位语从句，说明conclusion的内容。

15．When you go outing with your sisters，you must see to ________ that they are safe.
