Unlike the virginal, whose single set of strings runs parallel to the front edge of the instrument, the harpsichords several sets of strings are placed at right angles to its front edge.
老师,这道题我错选B选项,我的解题思路如下:首先进行选项分类,我排除了C\D,我认为which修饰前面的virginal, 所以前后的比较对象不正确(v和sets of strings比较了);另外,set of strings,主语是set,谓语动词不是应该用单数吗?D选项用了run; 请老师指出我解题思路中的问题,并讲一讲老师第一眼看到这个题是从何下手的,我看到这样的长选项就不知如何下手。谢谢老师!
