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。
