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.
BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error
BEAM robots learn to walk through trial and error by using brainlike circuits called neural networks instead of by programming them
BEAM robots are not being programmed to walk but instead using brainlike circuits called neural networks and learning to walk through trial and error
brainlike circuits called neural networks are used instead of programming for BEAM robots learning to walk through trial and error
brainlike circuits called neural networks are being used for BEAM robots that learn to walk through trial and error instead of being programmed
一个句子使用Instead强调要做的是后面内容，使用Instead of强调要做的的是前面的内容（instead of的内容是实际上不会发生、不会做的，表达的是一种否定语气）。
【简单说：Instead表达“而是要”，Instead of表达“而不是”nstead of 代替/而不是是个介词词组,后面通常跟名词、代词或动词的-ing形式等。】
主谓一致，排除DE；
时态：C选项现在进行时的被动语态不好，A一般现在时更优；
代词：B-programming them指代不清；
结构：C-but和instead语义重复
语义：比较A和B,本句想要比较的到底是什么呢？are programmed to work vs. learn to work.
B，learn by using circuits but not by programing,不能说通过程序化来学习，程序化就是已经编好程了，机器人执行程序就可以，不用再学习了
C，使用集成电路和学习走路并列错误，二者是有逻辑关系的；are being，are using时态不对，一般现在时就好。
C时态不对，不需要用一般进行时，用一般现在时即可；且learn to work和use brainlike circuits是有逻辑关系的，并非并列
Robots use circuits to learn to walk through trial and error，用集成电路来学习通过在试错中走路，through介宾作状语修饰walk，
through trial and error,试错，反复试验，如：
I have collected together over a period of time through trial and error .
I learned through trial and error the right way.
机器人被程序化VS机器人用集成电路来学习，这两件事情既可以用做为机器人的两个性质，共用一个主语，也可以分成两个并列句，robots和they分别做主语。
B，learn by using circuits but not by programing,不能说通过程序化来学习，程序化就是已经编好程了，机器人执行程序就可以，不用再学习了
C，使用集成电路和学习走路并列错误，二者是有逻辑关系的；are being，are using时态不对，一般现在时就好。
提主干！
这个新东西是这个新机器人，被pioneered。而不是说一个技术被pionnered.
instead/instead of
instead, 副词，表转折、代替，通常用于句尾
It will take days by car, so let’s fly instead.
instead of作介词，后面跟名词、动名词，如I will go instead of you.；Instead of doing it himself, he got a man to do it.
Instead of也可以做连词，后面还可跟形容词、副词、动词、不定式、介词短语和从句
makes him look younger instead of older
That increased instead of decreased our courage.
He proposes to do some work instead of to watch television.
B. Instead of by programming them的主语为BEAM robots，机器人自己不能为自己编程，该句逻 辑含义不通
C. but instead 前后不平行
D. E 的主语有问题吗？为什么神经网络不能被pioneered呢？
B中them没有合适的指代对象
hoice (b) says that robots are programming circuits, when it's supposed to say that humans are programming robots.
