大全47,扩散的问题,请教NN

1.        According to scientists at the University of California, the pattern of changes that have occurred in human DNA over the millennia indicate the possibility that everyone alive today might be descended from a single female ancestor who lived in Africa sometime between 140,000 and 280,000 years ago.


(A) indicate the possibility that everyone alive today might be descended from a single female ancestor who


(B) indicate that everyone alive today might possibly be a descendant of a single female ancestor who had


(C) may indicate that everyone alive today has descended from a single female ancestor who had


(D) indicates that everyone alive today may be a descendant of a single female ancestor whoD


(E) indicates that everyone alive today might be a descendant from a single female ancestor who


在BY书中提到:题中未划线部分的主语: X1(the pattern) of X2(changes)+that从句,定语从句是就近修饰of后面的名词X2还是OF前面的名词X2,可以由主谓一致进行判断.本题中that定语从句中的谓语动词have occurred决定了定语从句修饰复数名词Changes,如果谓语动词改为has occurred,修饰对象就是单数名词the pattern.


问题1:通过主谓一致去掉A,B,因为复数谓语与单数主语the pattern不一致,为什么主语不是changes?


问题2:在上面的说法中,如果原文中have occurred变成has occurred修饰复数名词Changes,会对indicate的主语是the pattern产生影响吗?

1。变化的模式暗示了,说明了。翻译过来模式是主语


2.那也应该是 the pattern of change that has occured,这样的话应该不会产生影响。因为这个不影响句子的意思。


i guess so

由问题一:是不是可以认为 X OF Y结构中,X就是核心词呢

X of Y, X is the focus word. X is the subject, except that if X is one of "some, any, all, most".

Even if it becomes "has occurred", still the subject is the pattern.
