答案与解析参考 

1-5: B B B B A
(前5题核心在于“陈述句语序”。只要看到宾语从句，先把选项里疑问句语序的排除掉。主句是Could/Can you开头表示委婉请求，从句时态根据实际情况定，通常为现在时态。)

6-10: A B B B B
(第8题：主句said是过去时，从句需用过去将来时would go。第9题：经典陷阱，客观真理永远用一般现在时。第10题：有or not，只能用whether，不能用if。)

11-15: A A C A A
(第11题：what作从句的主语，语序不需要改变。第15题：what's wrong with...句型中what本身就是主语，所以语序不变，但要注意主句asked是过去时，所以用was。)

16-20: B A B B B
(第16题：think缺少宾语，用what引导。第18题：主句didn't tell过去时，从句用过去将来时。)

21-25: A A B A B
(第21题：remember后面接陈述一件事实，且不缺成分，用that引导。第25题：doubt在肯定句中通常用if/whether引导，在否定句中用that引导。)

26-30: A B B C B
(第26题：主句过去时，从句动作发生在主句之前，用过去完成时had finished。第30题：注意拼写陷阱，weather是天气，whether才是是否。)
