题目内容
7．A：I will fail the exam without your help．B：If youdon'thelp me，I won'tpassthe exam．
分析 没有你的帮忙我考试不会通过．
如果你不帮助我，我考试不会通过．
解答 答案：don't，pass．上文的without表达的是没有…，结合下文的if引导的条件状语从句，是说如果你不帮助我，我考试不会通过．遵循主将从现的规则，主句will+动词原形，通过pass，从句主语you，故借助于do构成否定，故答案是don't，pass．
点评 without（表否定）没有，无，不需．如：
The letter was posted without a stamp．那封信没贴邮票就寄出去了．
We got there without any trouble．我们到了那儿，一路上没遇到任何麻烦．
You'll get wet if you go out in the rain without an umbrella．雨天外出不带伞会淋湿的．
