In 1995 Richard Stallman, a well-known critic of the patent system, testified in Patent Office hearings that, to test the system, a colleague of his had managed to win a patent for one of Kirchhoff's laws, which was an observation about electric current first made in 1845 and it is now included in virtually every textbook of elementary physics.

first made is a participle, so "it is now included" is not parallel

was不能修饰laws
AlexLTENN 2016-11-26 19:51:50
one of k's laws, which was 的was 错
janeandrebecca 2016-11-20 10:47:07
which修饰laws，即不应用was

it多余，laws和observation可做同位语。

which was不如同位语简洁，it多余

and前后连接了一个which was和一个it is，明显错

首先，本题考点，其实主要是同位语的修饰以及句子结构，定语从句 根据 A of B如果表示从属，the condition of the book which/that，此时，which that 都是修饰book，同样道理，one of the laws，K的定律之一，此时用that which 都是指代laws， 所以用复数，因此B E全排除，另外namely是个副词，此时要用namely最好是was+，所以排除C，D选项很隐蔽，两个独立句子，要么；要么，and才可以连接，单单是，而没有and是错的

and表平行，it is与made不平行；Which修饰laws后应接were

which 引导定语从句修饰 laws, was不正确
跳跳爸爸 2016-08-11 20:49:42
which引导定语从句修饰laws，就不应该用was
