【题目】应对寒潮灾害性天气,以下做法不恰当的是(  )

A.完全停止居民生活供水

B.加强预警,做好农业生产防护

C.对温室和畜舍等农业设施进行加固

D.及时清除高速公路和城市市区的路面积雪

【答案】A

【解析】

寒潮是冬半年影响我国的主要灾害性天气,指的是大范围的强冷空气活动。具体来说,长江中下游地区及其以北48小时内气温下降10℃以上,最低气温在4℃以下,且陆地上伴有5~7级大风,海上伴有6~8级大风,就可视为寒潮发生。寒潮南下使所经过的地区产生急剧降温、霜冻、大风,有时还伴随着雨雪天气。

寒潮来临时,完全停止居民生活用水是错误的做法,故A错误。为了应对寒潮,可加强预警,故B正确。对温室、大棚和畜舍等农业设施进行加固等,故C正确。及时清除高速公路和城市市区的路面积雪,故D正确。故选A。

【题目】 In today's world, sleep experts often say that for a better night's rest, Americans should turn off their smart phones or iPads before sleeping. Such electronic products make the brain more active, and then influence their sleep. But according to a latest survey, more than 90% of Americans often use a computer or some other kinds of electronic products in the hour before bed.

Researchers find that manmade light from some electronic products at night may reduce the brain chemicals that help to sleep. In the study, the researchers let volunteers read, play games and watch movies on a screen for different time while measuring how much light their eyes received. They found that two hours of sitting before a bright screen at night reduced the sleep chemical levels by about 22%.

Then the researchers studied the college students who often used computers at night. They got the similar results. And researchers say that may not only cause sleeplessness, but also raise the risk of obesity(肥胖症), diabetes(糖尿病) and other diseases.

To be on the safe side, the researchers suggest that we should use computer less than before, or turn down our screens as much as possible before sleeping.
