40. 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, an observation about electric current first made in 1845 and now included in virtually every textbook of elementary physics.
(A) laws, an observation about electric current first made in 1845 and
(B) laws, which was an observation about electric current first made in 1845 and it is
(C) laws, namely, it was an observation about electric current first made in 1845 and
(D) laws, an observation about electric current first made in 1845, it is
(E) laws
that was an observation about electric current, first made in 1845, and is
答案是A,同位语句-平行、简洁、句意完整 我没有疑惑
E: a colleague of his had managed to win a patent for one of Kirchhoff’s
laws that was an observation about electric current, first made in 1845, and is now included in virtually every textbook of elementary physics
但是E的解释我不懂: '
That appears to refer to laws rather than one'
跳跃修饰:
A of B that + modifier 修饰对象一般是A不是?!
为什么OG说that指代的是laws不是one?
难道GMAC不知道跳跃修饰?!! 还是说跳跃修饰这个语法点本身就不被GMAC正式承认?
求牛牛现身。。!!!
