126. More than thirty years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can "jump," as pearls moving mysteriously from one necklace to another.

as pearls moving mysteriously from one necklace to another
like pearls moving mysteriously from one necklace to another
as pearls do that move mysteriously from one necklace to others
like pearls do that move mysteriously from one necklace to others
as do pearls that move mysteriously from one necklace to some other one

答案是B,为什么,as 加句子不对吗

princess

最重要的一点是： pearl move这个情况并不是实际存在的，仅仅是一个类比，所以不能用do 或者can

Kilroy

as后面的助动词应该补can,和前面gene can平行
