PASSAGE TWO
问答题 According to the new research, what decides an individual's risk of osteoporosis?
【正确答案】Versions of the vitamin D receptor gene he inherits.
【答案解析】根据题目中的the new research和risk of osteoporosis定位到第6段第1句。该句说新的研究表明。一个人患骨质疏松症的几率很大程度上取决于他继承了哪种维生素D受体基因。题目用了decide来代替原文的depends heavily on,主语和宾语交换了位置,可见答案可从原文该句的宾语中获得,故为Versions ofthe vitamin D receptor gene he inherits。
问答题 Why is the new genetic finding said to be "a mixed blessing"?
【正确答案】Because that knowledge would make some relieved and others worried.
【答案解析】根据题目中的“a mixed blessing”定位到第8段。该段第3句提到,这一知识能让许多父母及其后代松口气,却会让其他许多人感到紧张,该句是对第1句概括句的进一步解释,可见这正是这一新发现成为喜忧参半之事的原因,限于字数要求,该句可转述为Because that knowledge would make some relieved andothers worried。
