请将上面题目一一说明理由,我会感激的.

1.B.不定式作结果状语,被动关系.
2.A have been doing表示 从过去到现在一直在做并可能继续做下去
3.D.seat 表“使某人坐下” 与人的关系是动宾即被动关系,手语绑也是被动,两个空都是宾语补足语,与宾语人的关系都是被动,并表示一般状态.
4.B.never...too 怎么做都不过分.
5.B.地点状语位于句首,完全倒装.
6.D.in search of sb.寻找某人,介词短语,search sb.动词短语表“搜某人的身”.search for sb.才是动词短语“寻找某人”
7.D.catch sb.doing.抓住某人正在做某事.
8.C.when （the girl was) asked about by her monther,括号部分为省略部分,因为从句主语和主句主语是同一人,且后跟系动词be,可以主系同时省略.
9.A give away 泄漏
10.C.should not have done本不该做（而实际上做了）,表责备语气.tell作介词without 的介宾,用动名词.
看到有人这么积极的学英语,很高兴.坚持下去!
