Well, there's a two-bedroom house in Newtown which is quite cheap.W：That'll be good, because it's very near the university. But if we all want our own rooms, it isn't really big enough.M：Too small.

Three-bedroom flat, close to the university...It's $400 a week.W：Oh, it's too expensive.M：Well, here's a three-bedroom house with a small garden.

If you like sports, particularly basketball, you are going to like this one. Have you heard about Jeremy Lin? He is an Asian-American player, and the subject of a film about his unusual career.92 foreign players from 39 countries began this season in the professional U．S. basketball league. That is more foreign players than ever before. But none is from Asia. At the moment, only one Asian-American plays in the U．S. National Basketball Association (NBA) and his name is Jeremy Lin. A new film called “Linsanity” shows Lin's unlikely road to becoming a star last season.Lin has always loved the game. He led his high school basketballteam to the state championship. But no college offered him an athletic scholarship. Lin attended Harvard, known as one of America's top universities. His playing broke Ivy League basketball records. Still, no NBA team signed him to play for it.As Lin struggled to prove he could play in the professional league, a group of Asian-American filmmakers began documenting his rocky start. Teams would hire him, but then remove him from the team. Evan Jackson Leong directed the project that watched Lin's career struggle upward, but then downward again.第二部分阅读理解(共两节，满分40分)第一节(共15小题；每小题2分，满分30分)21．C细节理解题。

综合能力测试题及答案
综合能力测试题及答案综合能力测试是一种综合评价个体在不同领域维度上的能力水平的评估工具。
下面将为您提供一道综合能力测试题及答案，希望对您的能力提升有所帮助。
题目：小明要给一本书设计封面，他需要在一张正方形的封面上画一个半圆形的图案，并且尽可能使半圆形图案的面积最大。
请问他应该选择怎样的半圆形图案，才能使面积最大化？答案：要使半圆形图案的面积最大化，需要选取一个半径尽可能大的半圆形。
由于封面是一个正方形，我们可以假设正方形的边长为x。
根据题目的描述，我们可以推导出半圆的直径应等于正方形的边长，即2r = x。
而半圆的面积公式为：A = πr²/2。
通过代入直径的关系式，我们可以将半圆面积公式中的r用x表示：A = π(x/2)²/2 = πx²/8。
现在我们的目标是使半圆形的面积最大化，换句话说，就是要找到一个最大的x值。
因为x代表正方形的边长，所以x必须大于0。
为了求得最大的x值，我们可以通过求导数的方法来解决。
对半圆面积公式求导数：dA/dx = (π/8)(2x) = πx/4。
令导数dA/dx等于0，即πx/4 = 0，解得x = 0。
但是，由于我们已经规定x必须大于0，所以此处的x值无意义。
另外我们还需要考虑边界情况，即当x趋近于0时或者趋近于无穷大时，半圆形的面积都会趋近于0。
综上所述，我们可以得出结论：小明应该选择直径等于正方形边长的半圆形图案，才能使面积最大化。
通过这样的综合能力测试题目，我们可以培养思维逻辑、数学运算和推导解决问题的能力，帮助提升解决实际问题的能力。
希望本次综合能力测试题及答案能对您有所帮助，谢谢阅读！。

第一章综合能力测试本试卷分第Ⅰ卷(选择题)和第Ⅱ卷(非选择题)两部分．时间120分钟，满分150分．第Ⅰ卷(选择题共60分)一、选择题(本大题共12个小题，每小题5分，共60分，在每小题给出的四个选项中，只有一项是符合题目要求的)1．2015年的世界无烟日(5月31日)之前，小华学习小组为了了解本地区大约有多少成年人吸烟，随机调查了100个成年人，结果其中有15个成年人吸烟．对于这个关于数据收集与处理的问题，下列说法正确的是()A．调查的方式是普查B．本地区约有15%的成年人吸烟C．样本是15个吸烟的成年人D．本地区只有85个成年人不吸烟[答案] B[解析]调查方式显然是抽样调查，∴A错误．样本是这100个成年人．∴C也错误，显然D不正确．故选B.2．某班的78名同学已编号1,2,3，…，78，为了解该班同学的作业情况，老师收取了学号能被5整除的15名同学的作业本，这里运用的抽样方法是()A．简单随机抽样法 B.系统抽样法C．分层抽样法 D.抽签法[答案] B[解析]所抽出的编号都间隔5，故是系统抽样．3．下列问题，最适合用简单随机抽样的是()A．某电影院有32排座位，每排有40个座位，座位号为1～40.有一次报告会坐满了听众，报告会结束后为听取意见，要留下32名听众进行座谈B．从10台冰箱中抽出3台进行质量检查C．某学校在编人员160人．其中行政人员16人，教师112人，后勤人员32人．教育部门为了解学校机构改革意见，要从中抽取一个容量为20的样本D．某乡农田有：山地8 000亩，丘陵12 000亩，平地24 000亩，洼地4 000亩. 现抽取农田480亩估计全乡农田某种作物的平均亩产量[答案] B[解析]A项的总体容量较大，用简单随机抽样法比较麻烦；B项的总体容量较小，用简单随机抽样法比较方便；C 项由于学校各类人员对这一问题的看法可能差异较大，不宜采用简单随机抽样法；D 项的总体容量较大，且各类田地的产量差别很大，也不宜采用简单随机抽样法．4．一个容量为50的样本数据，分组后，组距与频数如下：[12.5,15.5)，2；[15.5,18.5)，8；[18.5,21.5)，9；[21.5，24.5)，11；[24.5,27.5)，10；[27.5,30.5)，6；[30.5,33.5)，4.根据分组情况估计小于30.5的数据占( )A ．18% B.30% C ．60% D.92%[答案] D[解析] (2＋8＋9＋11＋10＋6)÷50＝92%.5．如图所示的是2006年至2015年某省城镇居民百户家庭人口数的茎叶图，图中左边的数字从左到右分别表示城镇居民百户家庭人口数的百位数字和十位数字，右边的数字表示城镇居民百户家庭人口数的个位数字，从图中可以得到2006年至2015年此省城镇居民百户家庭人口数的平均数为( )2 9 1 1 5 83 0 2 6 31247A.304.6B.303.6 C ．302.6 D.301.6[答案] B[解析] 由茎叶图得到2006年至2015年城镇居民百户家庭人口数为：291,291,295,298,302,306,310,312,314,317，所以平均数为291＋291＋295＋298＋302＋306＋310＋312＋314＋31710＝3 03610＝303.6.6．某地区共有10万户居民，该地区城市住户与农村住户之比为4∶6，根据分层抽样方法，调查了该地区1 000户居民冰箱拥有情况，调查结果如下表所示，那么可以估计该地区农村住户中无冰箱的总户数约为( )A.1.6万户 C ．1.76万户D.0.24万户[答案] A[解析]由于城市住户与农村住户之比为4∶6，城市住户有4万户，农村住户有6万户，调查的1 000户居民中共400户城市住户，有600户农村住户，其中农村住户中无冰箱的有160户，所以可估计该地区农村住户中无冰箱的总户数约为10×1601 000＝1.6(万户)．7．对某商店一个月内每天的顾客人数进行了统计，得到样本的茎叶图(如图所示)，则该样本的中位数、众数、极差分别是()12 52023

A[解析]本题考查了茎叶图的应用及其样本的中位数、众数、极差等数字特征，由茎叶图可知，中位数为46，众数为45，极差为68－12＝56.在求一组数据的中位数时，一定不要忘记先将这些数据排序再判断．8．有一个容量为200的样本，其频率分布直方图如图所示．根据样本的频率分布直方图估计，样本数据落在区间[10,12)内的频数为()A．18 B.36C．54 D.72[答案] B[解析]频率分布直方图中所有小矩形的面积之和为1，每个小矩形的面积表示样本数据落在该区间内的频率，故样本数据落在区间[10,12)内的频率为1－2×(0.02＋0.05＋0.15＋0.19)＝0.18，故样本数据落在区间[10,12)内的频数为0.18×200＝36.9.已知两个变量x ，y 之间具有线性相关关系，测得(x ，y )的四组值分别为(1,2)，(2,4)，(3,5)，(4,7)，则y 与x 之间的回归直线方程为( )A ．y ＝0.8x ＋3 B.y ＝－1.2x ＋7.5 C ．y ＝1.6x ＋0.5 D.y ＝1.3x ＋1.2[答案] C[解析] 利用排除法． ∵x ＝14(1＋2＋3＋4)＝2.5，y ＝14(2＋4＋5＋7)＝4.5，由于回归直线方程y ＝bx ＋a 必过定点(2.5,4.5)，故排除A 、D.又由四组数值知y 随x 的增大而增大，知b >0，排除B.10．某路段检查站监控录像显示，在某时段内，有1 000辆汽车通过该站，现在随机抽取其中的200辆汽车进行车速分析，分析的结果表示为如下图的频率分布直方图，则估计在这一时段内通过该站的汽车中速度不小于90 km/h 的约有( )A ．100辆 B.200辆 C ．300辆 D.400辆[答案] C[解析] 由题图可知汽车中车速在[60,90)的频率为10×(0.01＋0.02＋0.04)＝0.7， ∴在[90,110]的频率为(1－0.7)＝0.3.∴车速不小于90 km/h 的汽车数量约为0.3×1 000＝300辆．11.某人5次上班途中所花的时间(单位：分钟)分别为x ，y,10,11,9，已知这组数据的平均数为10，方差为2，则|x －y |的值为( )A ．1 B.2 C ．3 D.4 [答案] D[解析] 依题意，可得⎩⎪⎨⎪⎧10＝x ＋y ＋10＋11＋95，2＝15[(x －10)2＋(y －10)2＋(10－10)2＋(11－10)2＋(9－10)2]，⇒⎩⎪⎨⎪⎧ x ＋y ＝20，(x －10)2＋(y －10)2＝8，⇒⎩⎪⎨⎪⎧ x ＝12y ＝8，或⎩⎪⎨⎪⎧x ＝8y ＝12，所以|x －y |＝4.12．甲，乙，丙三名运动员在某次测试中各射击20次，三人测试成绩的频率分布条形图分别如图1，图2和图3，若s 甲，s 乙，s 丙分别表示他们测试成绩的标准差，则()A ．s 甲<s 乙<s 丙 B.s 甲<s 丙<s 乙 C ．s 乙<s 甲<s 丙 D.s 丙<s 甲<s 乙[答案] D[解析] 由频率分布条形图可得甲，乙，丙三名运动员的平均成绩分别为 x －甲＝0.25×(7＋8＋9＋10)＝8.5；x －乙＝0.3×7＋8×0.2＋9×0.2＋10×0.3＝8.5； x －丙＝0.2×7＋8×0.3＋9×0.3＋10×0.2＝8.5，s 2甲＝0.25×(1.52＋0.52＋0.52＋1.52)＝1.25；s 2乙＝0.3×1.52＋0.52×0.2＋0.52×0.2＋1.52×0.3＝1.45； s 2丙＝0.2×1.52＋0.52×0.3＋0.52×0.3＋1.52×0.2＝1.05，∴s 丙<s 甲<s 乙．第Ⅱ卷(非选择题 共90分)二、填空题(本大题共4个小题，每小题5分，共20分，将正确答案填在题中横线上) 13．一个容量为40的样本，共分成6组，第1～4组的频数分别为10,5,7,6，第5组的频率是0.10，则第6组的频率是________．[答案] 0.20[解析] 第5组的频数为40×0.10＝4，第6组的频数为40－(10＋5＋7＋6＋4)＝8，则频率为840＝0.20.14．(2015·广东文，12)已知样本数据x 1，x 2，…，x n 的均值x ＝5，则样本数据2x 1＋1,2x 2＋1，…，2x n ＋1的均值为________．[答案] 11[解析] 因为样本数据x 1，x 2，…，x n 的均值x ＝5，所以样本数据2x 1＋1,2x 2＋1，…，2x n ＋1的均值为2x ＋1＝2×5＋1＝11.15．(2014·江苏，6)设抽测的树木的底部周长均在区间[80,130]上，其频率分布直方图如图所示，则在抽测的60株树木中，有________株树木的底部周长小于100cm.[答案] 24[解析] 本题考查频率分布直方图．由题意在抽测的60株树木中，底部周长小于100cm 的株数为(0.015＋0.025)×10×60＝24.频率分布直方图中的纵坐标为频率组距，此处经常误认为纵坐标是频率．16．下图是某学校一名篮球运动员在五场比赛中所得分数的茎叶图，则该运动员在这五场比赛中得分的方差为________.(注：方差s 2＝1n [(x 1－x －)2＋(x 2－x )2＋…＋(x n －x )2]，其中x －为x 1，x 2，…，x n 的平均数)[答案] 6.8[解析] 本题考查茎叶图、方差的概念．由茎叶图知x －＝8＋9＋10＋13＋155＝11，∴s 2＝15[(8－11)2＋(9－11)2＋(10－11)2＋(13－11)2＋(15－11)2]＝6.8.三、解答题(本大题共6个小题，共70分，解答应写出文字说明、证明过程或演算步骤)

＝3000－(523＋487＋490＋510)＝990，现用分层抽样的方法在全校抽取300名学生，应在高三年级抽取的人数为：3003000×990＝99名．答：(1)高二年级有510名女生；(2)在高三年级抽取99名学生．19．(本小题满分12分)为了了解一个小水库中养殖的鱼的有关情况，从这个水库中多个不同位置捕捞出100条鱼，称得每条鱼的质量(单位：千克)，并将所得数据分组，画出频率分布直方图(如图所示)．(1)(2)估计数据落在[1.15，1.30)中的概率为多少；(3)将上面捕捞的100条鱼分别作一记号后再放回水库，几天后再从水库的多处不同位置捕捞出120条鱼，其中带有记号的鱼有6条，请根据这一情况来估计该水库中鱼的总条数．[解析] (1)根据频率分布直方图可知，频率＝组距×频率组距故可得下表：(2)0.30＋0.15＋0.02＝0.47，所以数据落在[1.15，1.30)中的概率约为0.47. (3)120×1006＝2000.所以水库中鱼的总条数约为2000条．20．(本小题满分12分)某农场为了从三种不同的西红柿品种中选出高产稳定的西红柿品种，分别在5块试验田上试种，每块试验田均为0.5公顷，产量情况如下表：[解析]因为x甲＝15(21.5＋20.4＋22.0＋21.2＋19.9)＝21.0(kg)，x乙＝15(21.3＋18.9＋18.9＋21.4＋19.8)＝20.06(kg)，x丙＝15(17.8＋23.3＋21.4＋19.9＋20.9)＝20.66(kg)，所以s甲＝15[(21.5－21.0)2＋…＋(19.9－21.0)2]≈0.756(kg)；s乙＝15[(21.3－21.06)2＋…＋(19.8－21.06)2]≈1.104(kg)；s丙＝15[(17.8－20.66)2＋…＋(20.9－20.66)2]≈1.807(kg)．由于x甲>x丙>x乙，s甲<s乙<s丙，所以甲种西红柿既高产又稳定．21．(本小题满分12分)潮州统计局就某地居民的月收入调查了10 000人，并根据所得数据画出了样本的频率分布直方图(每个分组包括左端点，不包括右端点，如第一组表示收入在[1 000,1 500))．(1)求居民月收入在[3 000,3 500)的频率； (2)根据频率分布直方图算出样本数据的中位数；(3)为了分析居民的收入与年龄、职业等方面的关系，必须按月收入再从这10 000人中用分层抽样的方法抽出100人作进一步分析，则月收入在[2 500,3 000)的这段应抽多少人？[解析] (1)月收入在[3 000,3 500)的频率为0.000 3×(3 500－3 000)＝0.15. (2)∵0.000 2×(1 500－1 000)＝0.1， 0．000 4×(2 000－1 500)＝0.2， 0．000 5×(2 500－2 000)＝0.25， 0．1＋0.2＋0.25＝0.55>0.5.∴样本数据的中位数为2 000＋0.5－(0.1＋0.2)0.000 5＝2 000＋400＝2 400(元)．(3)居民月收入在[2 500,3 000)的频率为0.000 5×(3 000－2 500)＝0.25， 所以10 000人中月收入在[2 500,3 000)的人数为0.25×10 000＝2 500(人)，再从10 000人中分层抽样方法抽出100人，则月收入在[2 500,3 000)的这段应抽取100×2 50010 000＝25(人)．22.(本小题满分12分)(2015·新课标Ⅰ理，19)某公司为确定下一年度投入某种产品的宣传费，需了解年宣传费x (单位：千元)对年销售量y (单位：t)和年利润z (单位：千元)的影响．对近8年的年宣传费x i 和年销售量y i (i ＝1，2，…，8)数据作了初步处理，得到下面的散点图及一些统计量的值．表中w i ＝x i ，w ＝，(1)根据散点图判断，y ＝a ＋bx 与y ＝c ＋d x 哪一个适宜作为年销售量y 关于年宣传费x 的回归方程类型？(给出判断即可，不必说明理由)(2)根据(1)的判断结果及表中数据，建立y 关于x 的回归方程；(3)已知这种产品的年利润z 与x ，y 的关系为z ＝0.2y －x .根据(2)的结果回答下列问题： (①年宣传费x ＝49时，年销售量及年利润的预报值是多少？②年宣传费x 为何值时，年利润的预报值最大？附：对于一组数据(u 1，v 1)，(u 2，v 2)，…，(u n ，v n )，其回归直线v ＝α＋βu 的斜率和截距的最小二乘估计分别为β^＝，α^＝v －β^u .[解析] (1)由散点图可以判断，y ＝c ＋d x 适合作为年销售量y 关于年宣传费x 的回归方程类型．(2)令w ＝x ，先建立y 关于w 的线性回归方程，由于d ^＝∑i ＝18 (w i －w )(y i －y )∑i ＝18 (w i －w )2＝108.81.6＝68， c ^＝y －d ^w ＝563－68×6.8＝100.6.∴y 关于w 的线性回归方程为y ^＝100.6＋68w ，∴y 关于x 的回归方程为y ^＝100.6＋68x .(3)①由(2)知，当x ＝49时，年销售量y 的预报值y ^＝100.6＋6849＝576.6，年利润z 的预报值z ^＝576.6×0.2－49＝66.32.②根据(2)的结果知，年利润z 的预报值z ^＝0.2(100.6＋68x )－x＝－x ＋13.6x ＋20.12， ∴当x ＝13.62＝6.8，即x ＝46.24时，z ^取得最大值． 故年宣传费为46.24千元时，年利润的预报值最大．。
