Pioneered by scientists at Los Alamos National Laboratory, BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error.

(A) BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error
(B) BEAM robots learn to walk through trial and error by using brainlike circuits called neural networks instead of by programming them
(C) BEAM robots are not being programmed to walk but instead using brainlike circuits called neural networks and learning to walk through trial and error
(D) brainlike circuits called neural networks are used instead of programming for BEAM robots learning to walk through trial and error
(E) brainlike circuits called neural networks are being used for BEAM robots that learn to walk through trial and error instead of being programmed

答案：A

大家请看A选项，分号隔开的是两个独立句子，而后一句子竟用代词they指代前一个句子的主语，不同的句子间怎么能相互指代呢？这难道不是严重的错误吗？有牛人来讨论一下！

可以
examples from OG10:

我想不通c项 BEAM robots are not being programmed to walk but instead using brainlike circuits called neural networks and learning to walk through trial and error 哪里错

A) BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error

原題說"用"brainlike circuits "來"學走路

C) BEAM robots are not being programmed to walk but instead using brainlike circuits called neural networks and learning to walk through trial and error

這邊變成把use跟learn同等連接 , 不一樣了 ,改變原句意思了

我觉得是are being错，怎么能一直programmed呢？对吧~~

cuishang11 · 发表于 2009-4-24 07:35:00

but using... and learning...

正确的逻辑意思应该是利用...去学 use...to learn...

use and learn 利用和学这里的“利用”就没有任何意义了

做题的时候，觉得A哪里都对，就是那个分号比较奇怪。

请问能把分号换成逗号吗？
