(·山东济宁模拟)How close parents are to their children a strong influence on the development of the childrens characters.

A. having

B. had

C. has

D. have

答案：

A. having

B. had

C. has

D. have

解析：C考查主谓一致。句意：父母与他们的孩子们的亲近程度对孩子们的性格培养有很大影响。题干中缺少谓语，故排除A项；“How close parents are to their children”作主语，谓语动词用单数形式，故排除D项；本句在介绍一种理论，故用一般现在时，故答案为C项。
