三道高一英语选择题：
1.Quite a few people used to believe that disaster ___ if a mirror was broken.
A:was sure of striking.B:was sure of having struck.C:was sure to be struck.D:was sure to strike.
答：D
译：有相当多的人过去曾经相信如果一面镜子被打破了,就一定会发生灾祸.
析：sth.is sure to happen是一个句型.其中sth.与happen是逻辑上的主动关系,用不定式的主动式.排除C.　sb.be sure of (doing) sth.表示某人对于某事的发生很有把握.这里的disaster不是人.感觉前面应有一个a的吧.
2.____ to turn off the electricity before you leave.
A.Make sure B.Be sure C:Surely D.Sure
答：这一题确实让人为难.ABD均可,以A为最佳.口语中用D也未必不可.
译：你离开之前一定要切断电源.
评：turn off的宾语应为电器,看题干知出题者水平和责任心有限.
3.We were astonished ______ the temple still in its original condition
A:finding B:to find C:find D:to be find.
答：B
译：看见那座寺庙依然保持原貌,我们大为吃惊.
析：sb.is +adj.to do sth.也是一个常见句型.如:　I am glad to meet you.
这一题较简单,D项是凑数项,不合出题要求.不必多说.
第一道和第三道我是不知道词组,第二道就觉得很为难.各位能提供解析么?

D, A或B都对，B，
make sure to do sth., be sure to do sth都可用于祈使句，表示“务必。。。”

DAB
第二道是祈使句，be动词引导的 记住就行了
