请教 og 189 和which的相关用法

盈儿

以下是引用amy7777在2006-10-4 12:40:00的发言：

OG11的解释:

The sentence presents three functions of intelligent computers，but these functions(to diagnose…，deciding… or other purposes) are not written in parallel ways．Moreover, the final function is vague．Turning this final function into an introductory statement and using parallel forms for the two dements diagnosing and deciding creates a stronger sentence．Either the clause，as an expert does, or the prepositional phrase, like an expert, is correct and idiomatic in this sentence．
    

按照这个解释,这两个词组都是对的,我看了这一题的所有贴子,大家都说是不同的,并且说like an expert好.

能给我确认一下吗,都不敢相信自已的眼睛,可是书上是这样印的呢.

谢谢.

相信OG吧，它才是bible

 Proponents of artificial intelligence say they will be able to make computers
        that can understand English and other human languages, recognize objects, and reason
        as an expert does-computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these.

分析：

黄颜色覆盖的地方是computers的定语，所以如果后面用as expert dose的话，大家可以简化句子，变成了：

they will be able to make computers as an expert does.

这个does代谁？它代的是make computers，则句子变成了expert makes computer，

违反了句意。
