Millions of Americans take vitamins and minerals, ____ that these pills can help to prevent serious illnesses.
A.convincing B.convinced
请问认为不应该是和主语之间的逻辑是主动的吗?为什么选择B呢
理解此处的Convince属性: Vt. 使确信;使相信;使信服;
convince sb. of sth.
convince sb. to do sth.
convince sb. that...
此处convince的作用对象是美国人,所以 和Americans 是动宾逻辑关系,故B正解。
