问题补充：

Your mother will be with you if she knows your grades.

A. pleased

B. pleasing

C. pleasure

D. pleasant

答案：

(答案→)A. pleased

B. pleasing

C. pleasure

D. pleasant

解析：根据be pleased with表示“对……满意”是固定短语，另外pleased一般修饰人，此处修饰Your mother；pleasant“令人愉快的”一般用来修饰事物，pleasure是名词。本句的意思是“如果你妈妈知道了你的成绩，她会很满意的。”所以本题选A。
