网考网解析：
本题为是非判断题。在第三段中提到“According to one study almost half of the children of two left-handed parents will be left-handed．”(据研究，由于父母都是左撇子，有近一半的孩子会是左撇子。)因此，A 是正确的。在第四段中提到“On the other hand, heredity alone cannot explain lefties. At least 84 percent of them are born of two right-handed parents.”(另一方面，遗传并不能完全解释左撇子现象。在左撇子当中， 84% 以上的人的父母都是右撇子。)因此，B 是正确的。在第二段中提到“They are one in ten of us who are left-handed…”(在我们当中，有十分之一是左撇子……)因此，C 是正确的。而 D 与第五段中提到的“In fact, almost equal numbers of individuals will favour either the right or the left.”(事实上，喜欢用右手和喜欢用左手的人数几乎相当。)不一致。 查看试题解析出处>>
