答案

1 may用于疑问句是多表请求 eg May I come in?
2 need 作情态动词时表示“有必要”.may在句中仍表示请求.
3 will 表示意愿,他愿意用你的自行车吗?这话不通啊.
4 未见选项
5 mustn't表示非常强硬的“禁止,不许”,can't的语气没有那么强硬
6 must强硬,表示“必须”,can表示“可以”.规定就是规定,不能商量,因此用must
7 从后半句看,本句表示建议而不是命令,因此用must不合适.
8 shall在第一人称作主语时表示请求,would更多表示“想要,愿意”,多用于表示语气委婉,客气.这里是对第一人称提问的,跟自己就别客气啦
9 两者比较时,除非前文已经出现过比较对象,否则不能用the+比较级
there are two girls.the younger one is my sister.
本句中不是这种结构,只是普通的选择疑问句的比较,因此不用the better.
