Question

Dust storms are violent and mostly unpredictable. They can cause property damage, injuries, and deaths, so it’s necessary to know what to do when you come across them.

     Watch out for dust storm warnings. Dust storms are most likely to occur on hot summer days, so listen to the local TV or radio broadcasts before traveling in hot, dry conditions, and consider changing or giving up your trip if dust storms are predicted. Roadside signs may also be able to warn you of dust storm danger.

     Be prepared. If you are in a storm-prone area, carry a mask(口罩) to keep out small dust particles (顆粒), and take eye protection to protect your eyes. A supply of water is also necessary.

     Go beyond the storm. If you see a dust storm from some distance, and you are in a vehicle, you should try to escape from it. Some dust storms can travel at more than 75 miles per hour, but they frequently travel much slower. However, it is not advisable to put yourself at risk by driving at high speed.

     Stay inside. Do not move about in a storm, as you will not be able to see hidden risks in your path. So if you’re in a house, stay inside.

     Protect yourself from flying objects. Cover as much of your body as possible. A dust storm’s high wind can carry heavy objects. If you find yourself without shelter, try to stay low, close to the ground, and protect your head with your arms, a backpack or a pillow.

【解析】

試題分析：本文主要講述了沙塵暴的有關(guān)信息以及在沙塵暴中如何保護(hù)自己不受傷害的具體措施。

1.C 推理題。根據(jù)本句However, it is not advisable to put yourself at risk by driving at high speed.說明在這種情況下迅速駕駛是不被建議的，故C項(xiàng)內(nèi)容正確。

2.C 細(xì)節(jié)題。根據(jù)文章倒數(shù)第二段Stay inside. Do not move about in a storm, as you will not be able to see hidden risks in your path. So if you’re in a house, stay inside.說明當(dāng)sand storm來臨的時(shí)候，盡量待在家里。故C正確。

3.D 細(xì)節(jié)題。我們需要眼鏡來保護(hù)眼鏡，需要牛奶給我們提供水分；需要毯子來保護(hù)自己。并沒有提及要使用旅游指導(dǎo)手冊。故D項(xiàng)符合要求。

4.D 細(xì)節(jié)題，ABC三個(gè)選項(xiàng)都是文章中提及在沙塵暴中保護(hù)自己的行為措施，D項(xiàng)內(nèi)容用盡可能多的東西蓋住自己，不符合文章的中心思想。

5.C 細(xì)節(jié)題。根據(jù)文章第二段告訴我們沙塵暴最可能是在夏天來臨，也告訴了我們沙塵暴的危害，在第四段中也告訴了我們沙塵暴的速度，唯獨(dú)沒有告訴我們歷史上最惡劣的沙塵暴是什么。故C項(xiàng)正確。
