【题目】— What should we avoid when we work out in summer?
— ______ when the temperature is over 32℃.
A. To run B. Running C. Having run D. To have run
在线课程【答案】B
【解析】
考查非谓语动词。句意：—夏季在外面工作时应该避免什么？—温度超过32度时要避免跑动。根据问题可知，如果把答语补充完整就是We should avoid running when the temperature is over 32℃. 而avoid doing sth.是固定搭配，避免做某事。故选B。
