这题目真不懂 When an active tooth in the shark’s jaws is lost or worn down, many spare teeth lie in seemingly limitless reserve, each of which are ready to slide into the appropriate position. A.

In the shark’s jaws, many spare teeth lie in seemingly limitless reserve, each one ready to slide into the appropriate position whenever an active tooth is lost or worn down. 假设a中are 改成is,这个句子也不对,因为run-on,而句子本身应该是each引导的独立主格结构才对。但是我不明白的是这里如果是is,那is 修饰which还是each,修饰each就run-on;修饰which,那句子就变成each of which,那也不对。如果把are去掉我觉得才表达独立主格的意思,而且我觉得这里which应该没有指代问题,怎么可能指代到jaws去呢?也不可能指代reserve,由each知which应修饰可数的复数,但reserve这里没看出来可以分成很多each啊 B就是指代错误 C也是指代错误,也是没搞明白are到底是which的谓语还是each,是each的谓语,是不是又run-on,不是得话,句子结构不完整 D我觉得如果按上面的人理解缺少谓语,那么is就是修饰which的。但我觉得这里可以看成句子主句就是 each one of which is ready to slide into the appropriate position whenever an active tooth is lost or worn down. E正确

A不正确是因为"are",each of which 其中的which只可能指代前面的teeth,因为reserve不可数,而跳跃修饰也不可能及"jaws",因为jaws在从句而非主句,所以此处只能用单数谓语。
each one 只能指代单数,因此正好修饰可数复数名词teeth,独立主格做伴随,表示功能,结果。
而且独立主格和定语从句的最大区别在于,独立主格修饰整个句子,而定语从句只修饰前面指代的名词,不能修饰整个句子。 |
