Answer 1

1，2，6，7题应该是正确的。第3题选A，你应先弄清楚主从句的关系，我认为是一种条件关系，译为“如果你找到一些不合适的，我们能在计划中做一些改变。” 第4题选C,remind sb. of sth.是固定搭配。第5题选B,这是一个非限制性定语从句，which指代前面整个句子，又做I think 后宾语从句的主语。第8题选C,the key to sth.是...的关键，就象the answer to the question结构一样。第9题选B，only to do为固定结构，但we 与tell 的关系为被动，故用only to be done.

Answer 2

第三题我觉得选A，表示一旦的意思，分清主句和从句的发生的先后顺序，根据句意理解应该是发现问题在进行修改，你选的时间顺序不对。
第四题选择C，remind sb of sth，固定搭配。
第八题选择C，the key to sth，固定搭配
第九题选择B，only+不定式，做结果状语，这里动词与逻辑主语是被动关系。
第二题从句意上看，说话者是对后面的不确定，进行提问，我选最后一个。
