Imagine you are Alice, stepping through the looking glass. Suddenly everything is re versed. Doorknobs are on the wrong side of doors. The gearshift in your car is in the wrong place. Twenty-five million Americans wake up every day in just such an awkward situation. They are the one in ten of us who are left-handed and must face the world designed for the right-handed majority. Why we are left-or-right-handed remains one of the great unsolved mysteries of science. We know that nearly two out of three lefties are male and that left-handedness runs in families. According to one study, almost half the offspring of two left-handed parents will be lefthanded. The Scots-Irish family Kerr (from the Gaelic word for "left")produced so many left-handers that in 1470 the family built its castle’s spiral stairways with a reverse twist to favor left-handed swordsmen. On the other hand, heredity alone cannot explain leffies. At least 84 percent of them are born of two right-handed parents. And in 12 percent of genetically identical twins, one will be right-handed, the other left. Perhaps the greatest puzzle of all is not why some people are left-handed, but rather why so few are. So, scientists are trying to discover the truth of the matter, and they are beginning to gain insight into many ways left-handed differ from right-handed by considering how their brains work.In the third paragraph, the word "offspring" means （）A. relativesB. sonsC. daughtersD. children

题目解答
答案
D
解析
本题考查根据上下文理解单词具体含义的能力。关键点在于结合句子中的逻辑关系和常识判断。句子中“two left-handed parents”与“offspring”构成父母与子女的关系，需明确“offspring”在此处特指“孩子”，而非其他亲属或单性别的后代。
句子分析：
原句为“almost half the offspring of two left-handed parents will be left-handed”，意为“大约一半的左撇子父母的孩子也会是左撇子”。
- “offspring”与“parents”构成对应关系，表示“子女”。
- 选项中：
- A. relatives（亲戚）范围过大，不符合“父母的孩子”这一限定；
- B. sons、C. daughters均为单性别，而“offspring”包含所有子女；
- D. children最准确，指“子女的总称”。
结论：根据上下文逻辑和常识，正确答案为D。
