题型：不详难度：来源：

Mary is very clever and      worth teaching , but her brother is not .Look ,he is now      asleep in class .

A．very ; very

B．much; very

C．well; very

D．well；fast

答案

D

解析

试题分析：考查固定搭配。固定搭配be well worth doing 值得做某事；用副词fast修饰形容词asleep.句意：Mary非常聪明，值得教，但是她的兄弟却不是这样。看现在课堂上他就要睡着了。故D正确。
点评：在高中的学习中平时要多积累固定搭配的用法，考试时只能凭借记忆力来答题，尤其是单项选择很难推出某个搭配的意思，所以平时的积累记忆是尤其重要的。学生可以将常考的全部积累在一起，通过反复的复习，从而达到永久的记忆下来。
