The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably on a spectrum of genetic relatedness.
请教B项的结构,highlights...and..overlooked,为什么时态不一致.还有,namely that they vary considerably什么意思,充当什么成分?
thanks
解答一下:
That some fraternal twins resemble each other greatly while others look quite dissimilar 主语,因为是个长句,所以必须前面加THAT的
highlights (谓语动词)
an interesting and often overlooked (这个OVERLOOKED是过去分词作为修饰后面feature的,和interesting 平行的)
feature of fraternal-twin pairs,
namely that they vary considerably(补充状语从句,对前面整个句子进行补充) ........
说的好 谢谢了
thanks !!!
