题型：不详难度：来源：

You should do the things worth ____, and if you have difficulty _____ them, you can turn to your family.

A．doing; doing

B．doing; to do

C．being done; to do

D．being done; doing

答案

A

解析

试题分析：考查固定句式。第一空是固定短语:be worth doing值得做；第二空是固定句式have difficulty (in) doing sth做某事有困难；句意：你应该做值得做的事情，如果你有困难，你可以向你的家人求救。故A正确。
点评：在高中的学习中平时要多积累固定句式的用法，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句式的意思，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。
