Answer 1

A， could 提问表示委婉语气，回答用原形

B  advice 不可数名词， 句中用than  要用比较级 less 修饰

应该是A吧， problem/ questions    第二空 用questions , a lof of 后用可数名词复数， ask 

    questions

4. A ,  hear 强调听的结果，听见。

第一题呢，选A。原因：could提问，表示提问人语气的委婉与礼貌；回答如果是同意，则果断用can来回答，表示你当然可以，这里没必要用must，不是必须；could也不用，can比could更能显示借出人的大方。
第二题嘛，用比较级且advice为不可数。
第三题选D,problem，question为不可数名词，整句意思是：现在的的麻烦是有很多问题去咨询。
第四题我拿不准，但是只可能在A与D之间，其他形式不符。
希望可以帮到你，有问题可以追加。
