Question

    You are walking down the street.  Suddenly it starts to rain and you don’t have an umbrella.  What do you do? Run or walk?

Most people would choose to run because it will get you out of the rain faster.  But if you run, you also run into more raindrops.  So what should you do?

Franco Bocci, a teacher at the University of Brescia in Italy, found that you should consider the wind direction and your body shape when you try to decide to move slowly or quickly in rain, according to the BBC.    

When there is no wind and the rain is landing directly on you, Bocci suggests that you should run as fast as possible.

But if the wind comes from behind and blows the rain onto your back, the best thing to do is walking at the same speed as the wind.  This way, both your front and back will stay mostly dry.

When the wind blows from the side, you'll have to think about one more thing—your body shape.  Thinner people are hit by fewer raindrops.  So a fatter person should run, while a thinner person should still try to match their speed to the wind.

“In general (大体来说)，the best thing is to run, as fast as you can—not always, but in general, Bocci told BBC News.  “If you’re really thin, it’s more probable that there will be an optimal speed.  Otherwise (否则），it is better to run fast. ”

Now you know what to do next time the rain catches you in the middle of the street.  But the best way to stay dry is still to carry an umbrella.

【解析】

本文是一篇说明文。当你正在街上走，突然下雨了，你是赶紧跑还是继续走？本文分析这与风向以及身材有关，并列举出种种情况。

1.细节理解题。根据上文“When there is no wind…you should run as fast as possible. ”可知，当下雨时没有风，尽量跑快点。故选B。

2.细节理解题。根据“both your front and back will stay mostly dry”可知，这种情况下前后身体能最大化地保持干燥。故选D。

3.细节理解题。根据“a thinner person should still try to match their speed to the wind”可知，更瘦的人需要思考风速问题。故选C。

4.词义猜测题。根据“a thinner person should still try to match their speed to the wind”可知，瘦的人需要考虑风速，如果步行速度和风速匹配上，那是最合适的，所以该单词的意思应该是“合适的，最佳的”。故选A。
