英语作文人工批改：关于as...as比较结构的一道单选题

—Do you have any idea what Paul does all day?
—As I know, he spends at least as much time playing as he _______.
A. writes   B. does writing     C. is writing      D. does write
这是2007年的重庆高考题，正确答案是B，但我不知道为什么A不可以，B答案 does writing 是什么意思？

—Do you haveany idea what Paul does all day?

—As I know, hespends at least as much time playing as he _______.

A. writes  B. does writing     C. iswriting      D. does write

这是省略，补全句子您可能就明白了：

As I know, he spends at least as much timewatching TV as he spends time writing. 据我所知，他花在看电视的时间至少和花在写作的时间一样多。

这里为避免重复，用does代替spends, writing与上文的playing相对。

我们还可这样改写句子：

As I know, he spends at least as much timewatching TV as he spends time writing.

= As I know, the time he spends playing is atleast as much as that he spends writing.

这就更容易看出上下文逻辑关系了。
