Question

---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

Answer

B

【解析】句意：-你知道Paul整体都做了什么吗？-据我所知，他在玩上花费的时间至少和在写作上的时间一样多。writes是动词的第三人称单数形式；does writing写作；is writing现在进行时；does write是助动词does后跟动词原形。这句话使用的句型是spend some time doing sth.，花费时间做某事，而且用了as...as表示比较，比较花时间玩和花时间写作，as后是一个从句，主语是he，动词应该是spends，但因为前面已经出现过spends，所以这里用助动词does代替；省略了宾语time，动词应用动名词形式。故应选B。这句话是完整表达是he spends at least as much time playing as he spends time writing。
