请教while后的形式：
在OG31题中E选项的错误(E)Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical skills.OG的解释In E, have a disinclination... while willing is grammatically incomplete。
而178题 In the last few years, the number of convicted criminals given community service* sentences. which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have *risen dramatically.
的正确选项为(E)sentences allowing them to remain unconfined while performing specific jobs that benefit the public has
两题都用了while，而且形式相同，那为什么178的while没有出现语法上不完整的现象？作者: sunny 时间: 2002-7-17 15:13
其实我做这个178题时产生了疑问，主要针对省略了什么内容，这种省略是否合法来考虑。
31题比较好理解，willing to 不是习惯用法，习惯上是be willing to 其中willing是形容词，所以省略的话，可能用being willing to 更合适些。178题好象performing没有问题，可能省略倒是有些问题。我当时的想法是可能前面的them已经指代了罪犯，后面的省略只能指罪犯而不会指sentences了。作者: zinco 时间: 2002-7-18 03:24
