问题 No direct relationship has been proven between high cholesterol levels and heart attacks. [br] Diet and physical qualities which passed down from our parents affect ____________________, a natural substance in the liver blood.
选项
答案 the amount of cholesterol
解析 本题定位信息是diet 和 physical qualities，从而锁定文章第四段第二句。该句提到The amount of cholesterol is affected by diet and by physical qualities we inherit from our parents。故本题应填the amount of cholesterol。题干将原文的被动语态改为了主动语态，并将本段首句改写成了所填词的同位语。
