189. 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.
(A)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
(B)as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan
(C)like an expert--computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan
(D)like an expert, the use of which would be for purposes like the diagnosis of equipment breakdowns or the decision whether or not a loan should be authorized
(E)like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like
正确选项是C。且不论其它方面的问题，单纯从句子分析，会发现C选项出现：like an expert的情况。他与什么比较？与computers，似乎数量不一；与reason---动作比，又无可比性；与computers reason 比，似乎应该用as an expert does。总之，在以前做本题时没注意，当时觉得挺顺的，但现在分析起来，反而糊涂了！

If you simplify "computers that can understand English and other human languages, recognize objects, and reason" as "computer" ( that ... is all referred to computer), then it's obvious to use "like a expert"; and also how to use "such as" can help you identify the correct one.作者: tongxun 时间: 2002-7-19 02:11
a expert 是单数，而computers 是复数，单复数可比吗？例如将前面的改写为：
Like a expert， computers。。。。。这样可以吗？种类不同、数字不同！作者: zinco 时间: 2002-7-19 02:24
In a word, as A do,B can do.....A and B must be the things that can be conpared. it is not enough that A and B only are the noun.A and B must be the analog.作者: zinco 时间: 2002-7-19 02:33
I think:
if there is no other choice such as the sentence-- like experts, computers..., the choice cited by tongxun, though not be the best choice, can also be the choice.作者: sunny 时间: 2002-7-19 20:27
