参考答案：D进入在线模考

从第二段开头这句，Ordinary computers work by following a chainlike sequence of detailed instructions(电脑的工作原理就是遵循一系列详细的指令)，可知选项A是正确的表达。从第二句，Although very fast，their processors can perform only one task at a time，可知B也是正确的表达。从第三句，This approach works best in solving problems that can be broken down into simpler logical pieces(在处理能够破解为更简单的逻辑编码的问题时，效果最好)，可知选项C也是正确的表达。另外第三段第一句Instead of program-ming a neural-network computer to make decisions，its maker trains it to…中的instead of就已经表明了没有给电脑编程去让它做决定，所以选项D是错误的表达。
