题目内容
19.-It's dangerous here.We must not let people fall down.--You're right.Come on!( )
| A. | stop…by falling | B. | keep…falling | ||
| C. | protect…falling | D. | prevent…from falling |
分析 --这里太危险了.我们一定不能让人掉下去.---没错.来吧.
解答 答案:D.根据题干,可知not let people fall down表示"不要让人掉下去",其意思就是"阻止人掉下去",ABC的搭配错误,故应排除,而prevent sb from doing 表示"阻止某人做某事",的故本题选D.
点评 本题的关键是正确辨析"阻止某人做某事"的固定用法.stop…from doing,keep …from doing,protect…from doing以及prevent …from doing 是同义短语.
