A.完全停止居民生活供水

B.加強(qiáng)預(yù)警，做好農(nóng)業(yè)生產(chǎn)防護(hù)

C.對(duì)溫室和畜舍等農(nóng)業(yè)設(shè)施進(jìn)行加固

D.及時(shí)清除高速公路和城市市區(qū)的路面積雪

【答案】A

【解析】

寒潮是冬半年影響我國(guó)的主要災(zāi)害性天氣，指的是大范圍的強(qiáng)冷空氣活動(dòng)。具體來說，長(zhǎng)江中下游地區(qū)及其以北48小時(shí)內(nèi)氣溫下降10℃以上，最低氣溫在4℃以下，且陸地上伴有5～7級(jí)大風(fēng)，海上伴有6～8級(jí)大風(fēng)，就可視為寒潮發(fā)生。寒潮南下使所經(jīng)過的地區(qū)產(chǎn)生急劇降溫、霜凍、大風(fēng)，有時(shí)還伴隨著雨雪天氣。

寒潮來臨時(shí)，完全停止居民生活用水是錯(cuò)誤的做法，故A錯(cuò)誤。為了應(yīng)對(duì)寒潮，可加強(qiáng)預(yù)警，故B正確。對(duì)溫室、大棚和畜舍等農(nóng)業(yè)設(shè)施進(jìn)行加固等，故C正確。及時(shí)清除高速公路和城市市區(qū)的路面積雪，故D正確。故選A。

【題目】 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(肥胖癥), 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.

說明：21、22題完成句子；23題簡(jiǎn)略回答問題；24題用英語(yǔ)簡(jiǎn)要概括文章的主旨大意；25題將文中畫線句子譯成漢語(yǔ)。
