21. 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

答案:C

我明白句子后的such as  的原则,如果不考虑句子后面的问题,在前面用as an expert does是不是也对?我理解as/like的区别,但是实际做题,经常没有把握.

谢谢.

LIke是介词，As是连词，介词后面跟名词，连词连接对等成分。
as an expert does我觉得应该可以。
