3道高二英语题
19.He wondered if he could slip out of the lecture hall without anyone ______
A.noticing
B.noticed
C.to notice
D.being noticed
20.He spoke in such a high voice_______out in the street.
A.as to be heard
B.to be heard
C.as to hear
D.to hear
21.Excuse me,could you tell me how to get to the Grand Hotel?I thought it was on this corner,but I seem to ______a mistake.
A.make
B.be making
C.having made
D.have made
19.A
翻译:他想知道,他是否可以在没人注意时溜出报告/讲学大厅.
without anyone ____是一个介词without的复合结构,此时需考虑宾语anyone和宾语补足语notice的关系.
很明显它们之间为主动关系,且notice和slip out of the lecture hall是同时发生的动作,所以只能用现在分词noticing做宾语补足语.
B/D都表示anyone和notice之间为被动关系,不符合逻辑,排除;
C表示notice该动作在slip out of the lecture hall发生时还没有发生,不符合逻辑,排除.
20.A
翻译:他用那么大的声音说话,以至于在街外面都能够(被人)听见.
固定搭配such/so...as to do sth,意思是“如此...以至于...”,由此排除BD;
而句子主语he和hear之间明显是被动关系,所以用被动结构to be heard,排除C.
21.D
翻译:打扰了,请问你能告诉我怎样去Grand Hotel吗?我以为它在这个角落处,但是我似乎(已经)犯/搞错了.
有seem to do sth和seem to have done sth的结构,但是没有seem to doing sth,由此排除C;
seem to do sth表示do sth是一般或将来的情况;
seem to be doing sth表示do sth是正在发生的情况;
seem to have done sth表示do sth是已经发生的情况.
从句意来看,make a mistake该动作当时已经发生,所以正确答案为D.
