It is about 120 kilometers long and 240 kilometers wide. It is a very important island because it is completely made of sand. In fact, it is the largest sand island in the world. There is no airport on the island, but there is a long beach along the east coast. Planes arrive and leave from here.The sand makes unusual shapes. There are hills made of sand called sandblows. Nothing grows on them. They move one or two meters a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island, such as Rainbow Gorge, The Cathedrals and Red Canyon, the sandy rocks have different colors. Sometimes the rocks are so brown that they turn the sea brown, like coffee. Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests-eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.About 500,000 people visit the island every year to see the island's beauty and nature. People enjoy camping and hiking(徒步) there. Unluckily, the visitors create problems. They damage plants and frighten animals. Their sun cream (防晒霜) makes the water dirty. So it is necessary to manage the visitors. For example, people may not use motor boats or go fishing in the lakes, and they need official papers to drive there.31.The passage is mainly about _____ .A.the shape of Fraser IslandB.nature on Fraser IslandC.the history of Fraser IslandD.daily life on Fraser Island32.From Para. 1 we know _____ .A.how large Fraser Island isB.Fraser Island is the largest islandC.many people live on Fraser IslandD.people will build an airport there33.The underlined word "They" in Para.2 refers to(指) the _____ .A.unusual shapesB.sandy hillsC.sandy rocksD.different plants34.From the 3rd paragraph we can infer (推断) that " _____ "is a kind of plant.A.eucalyptusB.owlC.curlewD.dingo35.Visitors may not be allowed to _____ on Fraser Island soon.A.camp and hikeB.go fishing in the seaC.wear sun creamD.drive without official papersⅣ.阅读还原The largest animal ever to live on Earth is the blue whale (鲸). It weighs about 80 tons-more than 24 big elephants. 36 A new baby whale weighs as much as a big elephant.Cats won't die if they fall off very high places because they can turn themselves up the right way so as to keep their bodies safe. 37 but it was just hurt a little.A bear can run as fast as a horse.A newborn panda is smaller than a mouse and weighs about 100 grams.38 A male(雄性) elephant may show his lady love for up to three years until the female(雌性) elephant takes his love. They often show their love by touching each other's body.39 For years a Canadian newspaper says that they would give anyone a lot of money if he or she could show that a wolf(狼) could hurt a person. 40 Wolves do not usually go together though（尽管）they may do this in winter and they only hurt people at an unusual time.根据短文内容，将下面方框内的句子还原到文中空白处，使短文内容完整、通顺。

初中数学八年级下册第二十章数据的分析单元检测练习试题一（含答案）某学校准备给教职工发放端午节福利，现随机对学校的一些教职工进行了粽子口味喜好的统计，并将统计结果绘制成如下图所示不完整的统计图，已知鲜肉粽15元/包，蛋黄粽12元/包，小枣粽和豆沙粽均为9元/包，调查中发现，每100人中，有40人喜欢蛋黄粽.（1）求出喜欢小枣粽的人数，并补全条形统计图；（2）假设此学校有教职工1000人，估计全校喜欢蛋黄粽的人数；（3）在（2）的基础上，学校预算1000元钱是否够买此次的福利粽；若不够，还差多少钱？【答案】（1）喜欢小枣粽的人数为120人，补全条形统计图如解图所示；见解析；（2）估计喜欢蛋黄粽的人数为400人；（3）学校预算的10000元不够，还需要2000元.【解析】【分析】（1）根据每100人中，有40人喜欢蛋黄粽，可以求出喜欢蛋黄粽的比例为40%，统计图中喜欢蛋黄粽的有240人，用上面所得比例估计总人数中喜欢蛋黄粽的人数比例，求出总人数，用总人数分别减去喜欢那三种粽子的人数即可解答；（2）用1000×蛋黄粽的人数占总比40%即可解答；（3）根据600人中喜欢每种粽子的人数所占比例，一次估算出1000人中，喜欢每种粽子的人数，从而求出每种粽子的数量，分别乘以各自单价，从而求出各自总价，进而解答.【详解】（1）由题知，抽查的总人数为：24040%600÷=（人）∴喜欢小枣粽的人数为60018060240120---=（人）.∴补全条形统计图如解图所示；（2）根据题意，喜欢蛋黄粽的人数占总比为40%，估计喜欢蛋黄粽的人数为100040%400⨯=（人）；（3）由（2）知，全校有1000名教职工，则喜欢鲜肉粽的人数有：1801000300600⨯=（人），喜欢蛋黄粽的有：100040%400⨯=（人），喜欢小枣粽的有：1201000200600⨯= （人），喜欢豆沙粽的有：601000100600⨯=（人），∴学校购买各类粽子所需要的费用为：30015400121009200912000⨯+⨯+⨯+⨯=元，∴学校预算的10000元不够，还需要12000100002000-=元.【点睛】本题考查条形统计图，突破此类问题的关键是数据统计图（表）的分析.错因分析：对统计图表中的数量关系理解不清，属于中等题..92．水果基地为了选出适应市场需求的小西红柿秧苗，在条件基本相同的情况下，把两个品种的小西红柿秧苗各300株分别种植在甲、乙两个大棚.对市场最为关注的产量和产量的稳定性进行了抽样调査，过程如下，请补充完整.收集数据从甲、乙两个大棚各收集了25株秧苗上的小西红柿的个数：甲26 32 40 51 44 74 44 63 7374 81 54 6241 33 54 43 34 51 63 64 73 6454 33乙27 35 46 55 48 36 47 68 8248 57 66 7527 36 57 57 66 58 61 71 38 4746 71整理数据按如下分组整理、描述这两组样本数据：（说明：45个以下为产量不合格，45个及以上为产量合格，其中45~65个为产量良好，65~85个为产量优秀）分析数据组样本数据的平均数、众数和方差如下表所示：得出结论a.估计甲大棚产量良好的秧苗数为________株；b.可以推断出________大棚的小西红柿秧苗品种更适应市场需求，理由为________________.（至少从两个不同的角度说明推断的合理性）【答案】120，乙；乙大棚里的秧苗众数产量比甲大棚里的多；乙大棚的秧苗产量方差比甲大棚的秧苗产量方差小，秧苗产量更稳定（答案不唯一）【解析】【分析】a．先完善两组样本数据表格，然后用样本数据中甲大棚产量良好的小西红柿株数÷25×300即得答案；b．从众数和方差两个方面进行比较即得答案．【详解】解：整理数据按如下分组整理、描述这两组样本数据：得出结论：a ．估计甲大棚产量良好的秧苗数为5530012025+⨯=； b ． ∵乙大棚里的秧苗众数产量是57，甲大棚里的秧苗众数产量是54，57>54；乙大棚里的秧苗产量方差是：215.04，甲大棚里的秧苗产量方差是：236.24，215.04<236.24；∴可以推断出乙大棚的小西红柿秧苗品种更适应市场需求；理由是：乙大棚里的秧苗众数产量比甲大棚里的多；乙大棚的秧苗产量方差比甲大棚的秧苗产量方差小，秧苗产量更稳定（答案不唯一）．故答案为：a ．120；b ．乙，乙大棚里的秧苗众数产量比甲大棚里的多；乙大棚的秧苗产量方差比甲大棚的秧苗产量方差小，秧苗产量更稳定（答案不唯一）．【点睛】错因分析：1．整理数据时记数错误；2．得出结论时没有掌握平均数、众数和方差的意义，没有掌握用样本估计总体．本题考查了平均数、众数、方差和用样本估计总体等知识，属于常考题型，熟练掌握基本知识是解题关键．93．甲、乙两名射击运动员在某次训练中各射击10发子弹，成绩如表：81且x乙=8，S乙2=1.8，S甲2=1.2，根据上述信息完成下列问题：（1）乙运动员射击训练成绩的众数是________，中位数是________．（2）求甲运动员射击成绩的平均数，并判断甲、乙两人在本次射击成绩的稳定性．【答案】（1）7；7.5；（2）甲在本次射击成绩的较稳定．【解析】试题分析：（1）根据出现次数最多的数为众数求出众数，然后从小到大排列这组数，取中间一个（共有奇数个）或两个的平均数（共有偶数个），即可得到中位数；（2）利用平均数的公式求出平均数，然后根据方差越小数据越稳定，可判断.试题解析：（1）乙运动员的成绩按照从小到大顺序排列为6，7，7，7，7，8，9，9，10，10，则乙运动员射击训练成绩的众数是7，中位数是（7+8）÷2=7.5；故答案为7；7.5；（2）甲运动员成绩的平均数为1×（8+9+7+9+8+6+7+8+10+8）=8.210（发）；∵S乙2=1.8＞S甲2=1.2，∴甲在本次射击成绩的较稳定．94．联合国规定每年的6月5日是“世界环境日”，为配合今年的“世界环境日”宣传活动，某实验中学课外活动小组对全校师生开展了“爱好环境，从我做起”为主题的问卷调查，并将调查结果分析整理后完成了下面的两个统计图．其中：A.能将垃圾放到规定的地方，而且还会考虑垃圾的分类；B.能将垃圾放到规定的地方，但不会考虑垃圾的分类；C.偶尔将垃圾放在规定的地方；D.随手乱扔垃圾．根据以上信息回答下列问题：（1）该校课外活动小组共调查了多少人？并补全条形统计图；（2）如果该校共有师生3060人，那么随手乱扔垃圾的约有多少人？【答案】（1）30人；详见解析；（2）随手乱扔垃圾的约有306人．【解析】【分析】（1）由条形统计图知，B种情况的有150人，由扇形统计图可知，B种情况的占总人数的50%，从而求出该校课外活动小组共调查的总人数．由统计图可求得D种情况的人数．（2）由（1）可知，D种情况的人数为300-（150+30+90）=30（人），从而求得D种情况的占总人数的百分比．已知该校共有师生3060人，便可求出随手乱扔垃圾的人数．【详解】解：（1）由统计图可知B种情况的有150人，占总人数的50%，所以调查的总人数为150÷50%＝300（人）D种情况的人数为300﹣（150+30+90）＝30人；（2）因为该校共有师生3060人．所以随手乱扔垃圾的人约为：3060×30÷300＝306（人）．答：随手乱扔垃圾的约有306人．【点睛】本题考查的是条形统计图和扇形统计图的综合运用，读懂统计图，从不同的统计图中得到必要的信息是解决问题的关键．条形统计图能清楚地表示出每个项目的数据；扇形统计图直接反映部分占总体的百分比大小．95．某单位组织职工观光旅游，旅行社的收费标准是：如果人数不超过25人，人均旅游费用为100元；如果超过25人，每增加1人，人均旅游费用降低2元，但人均旅游费用不得低于70元．该单位按旅行社的收费标准组团，结束后，共支付给旅行社2700元．求该单位这次共有多少人参加旅游？【答案】该单位这次参加旅游的共有30人．【解析】【分析】设该单位这次参加旅游的共有x人．因为100×25=2500＜2700，所以x ＞25，根据题意可列方程得，[100-2（x-25）]x=2700，解方程即可求解。
