In some cases, dust and sand may set a limit to a shallow depth by a low-lying temperature change. 1 Drought is another cause of sandstorms. Poor farming practices make dust and sand free of protection from the wind. 2 A sandstorm can transport and carry large amounts of sand. Deserts are the key source of sandstorms. Saharan sandstorms have increased about 10 times during the half century since the 1950s, causing topsoil (表土层) loss in nearby countries. 3 Sandstorms have also been shown to increase the spread of disease across the globe. Viruses in the dust are blown into the atmosphere by the storms. Some diseases may not be urgent at the very beginning, but they can develop into deadly ones if left untreated. 4 Sandstorms cause soil loss from the dry land, doing harm to agriculture. Sandstorms also reduce visibility, affecting airplanes and road transportation. 5 Dust can also have good effects. Central and South American rainforests get most of their mineral nutrients from the Sahara; iron-poor ocean regions get iron. A．This is one of the effects of sandstorms. B．Bad results are caused by sandstorms. C．Dry land farming is one of the most serious practices. D．People know little about the effects about sandstorms. E．In other cases, dust may be blown as high as 6,100 meters high. F．For example, a breathing problem can lead to lung cancer, while dry eyes lead to blindness. G．In addition, sandstorms also discourage visitors from visiting these places, striking tourism. 六、语法填空 阅读短文，在空白处填入适当的内容或括号内单词的正确形式。 Be pleased to do anything even though it is very tiny. In fact, there’s no single thing that is not 1 (值得的) doing or you are not able to do. So 2 (live) a happy life with a light heart is the most important. Then how can you live a happy life? Make each day meaningful by helping someone or just making someone smile. The feeling 3 makes you want to help others stays at the bottom of your heart. Happiness depends 4 your feelings in your heart. Helping others is helping 5 (you). 6 (face) difficulties bravely in your life. Everyone may meet with difficulties. No one can 7 (避免) them. The difficulties can teach you a lot. They will help you to be closer to 8 (successful). Never worry about the things you can’t change. Worrying can 9 change the situation nor solve any problem. Perhaps, not every dream will be realized. Never mind, and take it easy. Come on, everybody! Let’s live a happy life with a light 10 and enjoy the beautiful sunshine every day. 1 / 9 学科网（北京）股份有限公司 $$ Unit 4 Period 3 Discovering Useful Structures分层练习 基础达标 01 能力提升 02 拓展培优 03 一、单词拼写 1.

Sandstorms also reduce visibility, affecting airplanes and road transportation.(沙尘暴造成旱地土壤流失，危害农业。沙尘暴还会降低能见度，影响飞机和公路运输)”可知，本句主要承接上文，对沙尘暴造成的其他影响进行说明。故G选项“此外，沙尘暴也使游客不愿去这些地方，从而打击了旅游业”符合语境，故选G。 六、语法填空 阅读短文，在空白处填入适当的内容或括号内单词的正确形式。 Be pleased to do anything even though it is very tiny.
