题目内容
12．当你遇到困难时，为什么不请求帮助呢？Why not/Why don't you ask for help when you're in trouble？
分析 Why not/Why don't you
解答 答案：Why not/Why don't you．
首先通过中英文句子的比对，可知英文句子中缺少"为什么不"的表达．短语"为什么不"的英文表达是：Why not/Why don't you．该句式用来提建议，后面跟动词原形，故答案为：Why not/Why don't you
点评 做这类题型，首先根据所给汉语明确句子所要考查的单词或短语的拼写，再结合相关语法知识对单词或短语做出形式上的变化．
