问题解答:

我来补答
解题思路: 如下
解题过程:
( )1. Do you help your parents ______ housework?
A. doing B. do C. does D. did
正确答案是B。此题考查动词help的用法 。其常用用法是:help sb do sth或help sb to do sth.意为“帮某人干某事”。help后的不定式符号to既可以省去也可以带上。不存在help sb doing sth .的用法,切记。例如:He often helps me(to)study English.他经常帮助我学英语。
( )5. He’ll send you an e-mail as soon as he ________ in Shanghai.
A. will arrive B. arrive C. arrives D. will arrives
正确答案是C。此题考查主将从现现象。
as soon as引导时间状语从句,表示“一……就……”。如果主句用将来时,从句必须用一般现在时代替将来时。如:
  I’ll tell him the news as soon as he comes.
  他一来我就告诉他那消息。
As soon as I get to Beijing,I'll write to you.我一到北京,就给你写信。
同学,你好,因网站有一次解答一道题的规定,所以其他的问题的请另行提问,谢谢合作!
最终答案:略
