1 shop assistant

2 hung

3 hanged 3．多项选择题答案

1. b

根据课文第3-4行If the Houses of Parliament had not been burned down in 1834 可以判断只有b.符合课文内容，其他3个选择都与课

相同.a. the hour 不能引导从句, c. really, d. indeed 都是副词,都不能引导从句,只有b. the moment(当……时，一……就)与when 意思相同，并可以引导时间状语从句，所以选b.

12. a

went slowly 慢慢地走,和前一句的the clock slowed down(钟变慢了)意思不同.

只有a. was slow(慢了)和前一句意思相符合,所以选 a. 而 b. was behind(在后面), c. went back(回去), d. went slowly(慢慢地走)都与前一句含义不符合.
