【参考答案】1．【答案】B【解析】细节理解题。根据“Itisabout9,000,000squarekilometresinsize.ThisisalmostthesizeofAmericaorChina.”可知，撒哈拉沙漠的面积几乎相当于美国或中国的面积。因此，正确答案是B。2．【答案】A【解析】代词指代题。根据“Becauseofthehightemperaturesandpoorconditionsofthedesert,onlyafewplantslivehere,justabout500kinds.”可知，画线部分“They”指代的是前面提到的高温和恶劣的条件。因此，正确答案是A。3．【答案】D【解析】细节理解题。通读全文可知，第一段介绍了撒哈拉沙漠的面积，第二段介绍了它的地形，第三段介绍了它的温度，第四段介绍了该地区的人口、语言和文化，未提及它的未来。因此，正确答案是D。4．【答案】D【解析】细节理解题。根据“Becauseofthistherearemanydifferentculturesandlanguagesinthisarea.”可知，撒哈拉沙漠拥有丰富的文化和语言。因此，正确答案是D。5．【答案】C【解析】推理判断题。通读全文可知，本文主要介绍了撒哈拉沙漠的相关内容，故推出我们最有可能在地理书上看到这篇文章。因此，正确答案是C。6．【答案】B【解析】根据上文“...floodsallovertheworldaregettingmoreandmoreserious.Alotoflandhasgonewiththem.”可知，因为人们滥砍滥伐，洪水越来越严重，许多土地也随之流失。最后一句应是对前面内容的总结：这是来自自然界的一次教训。因此，正确答案是B。7．【答案】A【解析】根据上文“...theyoftencutdowntreesorpulloutmanywildplantstomakefarmland.”和下文“Theyalsodon’tknowthattreescanstopfloods...manyofthesewildplantsarefoodforsomewildanimals.”可知，正确答案是A。8．【答案】E【解析】根据上文“…orthatmanyofthesewildplantsarefoodforsomewildanimals.”和下段中的“Nowthedeerhadnothingtoeatandmanyofthemdied.”可知，此处表示“如果动物找不到足够的植物吃，它们将会饿死或不得不离开这个地方”。因此，正确答案是E。9．【答案】D【解析】根据上文“Thenthedeerbegantoeatthegreenleavesoftheyoungtrees.”和下文“Nowthedeerhadnothingtoeatandmanyofthemdied.”可知，鹿没有东西吃，很多都饿死了，结合选项推断，鹿没有东西吃是因为人们开始想办法保护他们的树。因此，正确答案是D。10.【答案】C【解析】根据前面文章内容及最后一段的陈述“Peopletrytoplantmanymoretreesandgrass,toprotectwildplantsandallkindsofwildanimals,eventigers.”可知，最后这一句是对全文中心思想的总结。因此，正确答案是C。11．【答案】B【解析】bring带来；watch观看；ask询问；help帮助。联系常识可知，此处指去泰山看日出。因此，正确答案是B。12．【答案】C【解析】shortest最短的；highest最高的；longest最长的；widest最宽的。根据“thesecond...oneistheYellowRiver”可知，此处指黄河是第二长河。因此，正确答案是C。13．【答案】D【解析】light灯；tradition传统；background背景；birthplace发源地。根据“becauseChineseancestorswerebornintheareas”可知，这里是中国文化的发源地。因此，正确答案是D。14．【答案】C【解析】thanksto多亏；welcometo欢迎来到；comparedto与……相比；nextto挨着。根据“...theriversinChina，therearealsoagreatnumberoflakes.”可知，相比于河流，中国还有大量的湖泊。因此，正确答案是C
