标题: 885-b3

It may be that by focusing primarily on a patient’s mental condition and on vague and often very speculative psychodynamic factors, predictions about the patient’s future behavior decrease in accuracy.

(A) predictions about the patient’s future behavior decrease in accuracy

(B) mental health professionals lessen the accuracy of their predictions about the patient’s future behavior

(C) the accuracy of predictions about the patient’s future behavior lessens

(D) a decrease in accuracy is seen in predictions about the patient’s future behavior can be predicted less accurately

(E) the patient’s future behavior can be predicted less accurately

 

请教:为什么选B,mental health professionals 是后加的,不算改变原句意思吗?

我选了C,不知错在哪里,呵呵,请高手不吝赐教

只能选B了,因为前面by -ing词组限定了后面的主语是-ing的发出者
