How often do you use your car? Can you use your car less often? Do you know the following facts in the UK? ·About 50% of all car journeys are just for fun. ·Over 80% people go to work by car. ·25% car journeys are under two miles. ·70% car journeys are under five miles. WALKING & CYCLING Instead of using the car for short journeys, why not walk or ride a bicycle? Walking is the most popular form of exercise—it’s healthy and it can save money. If you work nearby, try walking or cycling instead of driving. Walking your children to school gives them valuable road experience. BUSES Bus companies are using new buses: some run on new fuels which produce less pollution; some have easier access(通路)for disabled and old people. There are special traffic lanes (行车道)to make bus journeys easier. So do something to help solve the pollution problem—let the bus take you to work and your children to school. TRAINS All car journeys, long or short, can be hard work. For some trips, it is wiser to take the train. Leave your car at home and walk, cycle or take a bus to and from the station. Train travel is fast, safe and comfortable. Train tickets are not always expensive. 20. How many of car journeys are just for fun in the UK? A. 25% B. About 50% C. 70% D. Over 80% 21. The writer believes that _________ can give children valuable road experience. A. walking to school B. travelling by train C. taking new fuel buses D. having car journeys for fun 3

22. What does the writer think of travelling by train? A. Tiring B. Exciting C. Terrible D. Comfortable

B Most people want to be happy, but few know how to find happiness. Money and success alone do not bring lasting happiness. Aristotle, a Greek thinker, said, “Happiness depends on ourselves.” In other words, we make our own happiness. Here are a few suggestions to help you be happier. The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future-for example, getting into college or getting a good job-that we fail to enjoy the present. You should enjoy life’s simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have several close friends often live happier and healthier lives. Another secret to living a happy life is to be active, and have hobbies where you forget your problems and time. Many people experience dancing, or playing a sport, such as swimming. You can forget about your problems, and only think about the activity. Finally, many people find happiness in helping others. Studies show that people feel good when they spend their time helping others. If you want to feel happier, do good things for someone. You can help a friend with his or her studies, go shopping to buy food for an elderly person, or simply help out around the house by washing the dishes. 23. What/Who makes happiness for us? A. Most people B. Money C. Success D. We ourselves 24. The second paragraph tells us that ________. A. we shouldn’t think about our future. B. some people fail to live a happy life. C. happiness is to enjoy the simple things in life. D. the more friends you have, the happier you will be. 25. The passage gives us ________ pieces of advice on happiness. A. one B. two C. three D. four 26. Which of the following is not mentioned in the passage? A. Reading a good book B. Traveling to a foreign country C. Playing a sport D. Spending time with close friends 27. What is the underlined “close” mean? A. within a short distance B. liking and knowing each other very well C. seeing each other very often D. evenly matched

D.40°(2)如图2,P是三角形ABC内一点,比较∠BPC与∠A的大小并简单说明理由.(3)如图3,∠1=27.5°,∠2=95°,3=38.5°,那么∠4=.2016年北京市第十届“学而思杯”综合能力测评试卷(六年级样卷)参考答案与试题解析一、填空题1.(4分)下面这几个图形中,阴影面积占总面积的的图形有2个.【分析】判断出每个图形被平均分成了几份,阴影部分占几份,即可判断出阴影面积占总面积的的图形有多少个.【解答】解:左起第一个图形中阴影面积占总面积的:=;左起第二个图形中阴影面积占总面积的:=;左起第三个图形中阴影面积占总面积的;左起第四个图形中阴影面积占总面积的:=.所以阴影面积占总面积的的图形有2个.故答案为:2.【点评】此题主要考查了分数的意义和应用,要熟练掌握,解答此题的关键是判断出每个图形的阴影面积占总面积的几分之几.2.(4分)三个互不相同的质数的和是10,那么,这三个质数的乘积是30.【分析】三个质数和是10证明这三个数都是个位数,个位数字是质数的有2,3,5,7.找出满足条件的即可.【解答】解:小于10的质数有2,3,5,7四个数字.数字和为10的是2+3+5=10,2×3×5=30.故答案为:30.【点评】要知道什么是质数,还必须掌握100以内25个质数方便计算.此类型题用枚举法比较直接简单.3.(4分)学而思教研部一共购买了300本书,其中有五分之二是数字书,三分之一是语文书,其余是英语书.那么,英语书共有80本.【分析】把书的总本数看作单位“1”,那么英语书的本数占总本数的(1﹣﹣),单位“1”已知用乘法计算即可.【解答】解:300×(1﹣﹣)=300×﹣300×﹣300×=300﹣120﹣100=80(本)答:英语书共有80本.故答案为:80.【点评】本题考查了分数较复杂的乘法应用题,关键是确定单位“1”,解答依据是:求一个数的几分之几是多少用乘法计算.4.(4分)如图,有一个棱长是10厘米的正方体木块,从它的上面、前面和左面的中心分别凿穿一个边长为4厘米的正方形孔,穿孔后,木块剩余部分的体积是648立方厘米.【分析】根据题干可得,这个图形剩下的体积等于原正方体的体积减去3个长宽高分别是4厘米、4厘米、10厘米的小长方体的体积,因为最中间的边长为4厘米的小正方体被多减了2次,所以再加上2个边长4厘米的小正方体的体积,就是这个图形剩下的体积.【解答】解:由分析可知:木块剩余部分的体积是10×10×10﹣4×4×10×3+4×4×4×2=1000﹣480+128=648(立方厘米)故答案为648.【点评】解答此题的关键是明确剩下的体积比原来正方体的体积减少了哪几个部分.二、填空题5.(5分)请计算:当a+2b=5,c=3时,代数式5c﹣2b+[3a﹣(3c﹣12b﹣2a)]的结果是31.【分析】去括号,整理再代入,即可得出结论.【解答】解:5c﹣2b+[3a﹣(3c﹣12b﹣2a)]=5c﹣2b+3a﹣3c+12b+2a=2c+10b+5a=6+5×5=6+25=31,故答案为31.【点评】本题考查代换问题,考查去括号的运用,比较基础.6.(5分)如图,正方形ABCD边长为40厘米,其中M、N、P、Q为所在的中点:分别以正方形的顶点为圆心,以边长的一半为半径做直角扇形,那么形成图中阴影部分的面积是344平方厘米.(π 取3.14)【分析】从图中可以求出看出:阴影部分面积=正方形ABCD的面积﹣四个四分之一圆的面积=正方形ABCD的面积﹣1个圆的面积【解答】解:小圆的半径=20厘米;一个小圆的面积=πγ2=1256平方厘米;阴影部分面积=正方形ABCD的面积﹣1个圆的面积=40×40﹣1256=344平方厘米.故:应该填344.【点评】找出阴影部分面积的等量关系即可.7.(5分)一个五位数,各位数字互不相同,并且满足:从左往右,第一位是2的倍数,前两位组成的两位数是3的倍数,前三位组成的三位数是5的倍数,前四位组成的四位数是7的倍数,这个五位数是11的倍数.那么,这个五位数最小是21076.【分析】根据题意确定出各位的数字即可解决问题.【解答】解:因为万位是2的倍数,故万位最小应为2,前两位组成的两位数是3的倍数,故前两位最小应为21,前三位组成的三位数是5的倍数,故前三位最小应为210,前四位组成的四位数是7的倍数,故前四位最小应为2100,但是要求各位数不同,故应为2107,这个五位数是11的倍数,故此数为21076.故答案为21076.【点评】本题考查最大与最小、数的整除特征等知识,确定符号条件的各位的最小的数字是解题的关键.8.(5分)填入合适的数字,使如图所示乘法竖式成立.两个乘数的和是925.【分析】根据第一个因数的个位与第二个因数十位乘积的末位数是1,可确定第一个因数和第二个因数的十位是1,或9,或3、7,如是1,第二个因数的十位与第一个因数相乘的积是二位数,与算式矛盾;如是9,则第一个因数应是几十九,它与2的乘积不可能得到几百零几,所以第一个因数的个位是3或7,如是7,则第一个因数应是几十七,它与2的乘积不可能得到几百零几,所以第一个因数的个位是3,第二个因数的十位是7,据此可推出第一个因数的十位是5,进而推出第二个因数的百位是8.【解答】解:53+872=925答:两个乘数的和是925.故答案为:925.【点评】本题的重点是根据第一个因数的个位与第二个因数十位乘积的末位数是1,来推出第一个因数和第二个因数十位上的数是多少.三、填空题9.(6分)有浓度为30%的盐水若干,加入100克水后浓度变为20%,原有浓度30%的盐水200克.【分析】根据公式浓度=%.水的浓度是0%,利用十字交叉法即可求解.【解答】解:根据浓度问题的十字交叉法得.混合前的浓度是30%和水的是0%,混合后的浓度是20%,列出十字做差,在一直线上大减去小得,30%﹣20%=10%.20%﹣0%=20%,得到浓度差是20%和10%.浓度差的比值就是2:1.再根据浓度差的比等于溶液的质量比.也就是30%的溶液质量比谁的溶液质量是2:1.100×2=200(克).【点评】十字交叉法是浓度问题中的重要方法,对应量分别是溶液质量﹣混合前浓度﹣混合后浓度﹣浓度差﹣浓度差的比.特别注意纯酒精(溶质)浓度是100%,水的浓度是0%.10.(6分)算式(﹣)×(﹣)×(I﹣J)=2014中,不同的字母代表不同的数字,那么两位数的最大值是98.【分析】对2014进行分解质因数可以得到2014的质因数有2,19,53,作出假设,猜想,结合实例(98﹣45)(36﹣17)(2﹣0)=2014,即可解决问题.【解答】解:因为2014=2×19×53,故知I﹣J=2,另外两个括号分别是19和53;或者I﹣J=1,另外两个括号分别是38和53,的理论最大值为98,另一方面有实例(98﹣45)(36﹣17)(2﹣0)=2014,故答案是98.【点评】本题考查数字问题,解题的关键是学会质因数分解,学会假设、猜想,需要熟练掌握数字之间的运算规则.11.(6分)如图,三角形ABC是直角三角形,M是斜边BC的中点,MNPQ是正方形,N在AB上,P在AC上.如果,AB的长度是12厘米,AC的长度是8厘米.那么,正方形MNPQ的面积是20平方厘米.【分析】如图,作MD⊥AB于D,以AD为外围正方形的边,作出以MN为内含正方形的弦图.根据S=S正方形ADEF﹣4•S△DMN计算即可.正方形MNPQ【解答】解:如图,作MD⊥AB于D,以AD为外围正方形的边,作出以MN为内含正方形的弦图.易知DM=AN=AC=4,AD=AB=6,∴DN=6﹣4=2,=S正方形ADEF﹣4•S△DMN=62﹣4××2×4=20cm2,∴S正方形MNPQ故答案为20.【点评】本题考查三角形的面积、弦图、正方形的性质等知识,解题的关键是学会添加辅助线,构造弦图解决问题.12.(6分)将数字1~6填入空格中,使每行、每列及每个粗线宫内数字不能重复.灰色粗线两侧格内数字之差为1,没有灰色粗线的相邻两格内数字之差不为1.【分析】根据灰色粗线两侧格内数字之差为1,先填灰色粗线另一侧的数字,再根据没有灰色粗线的相邻两格内数字之差不为1,逐步填入数字,可得结论.【解答】解:根据数独规则就是要求在每个区域内出现的数字都为1~6,从左列第二个3×2入手,6右边是5,4右边是3,3右边只能是1,可得填右列第二个3×2,5的左边是6,6的上边是3,可得其它两格的数,可得根据灰色粗线两侧格内数字之差为1,可得填右上方3×2,根据灰色粗线两侧格内数字之差为1,可得填右下方3×2,可得填左上方3×2,可得填左下方3×2,可得【点评】本题考查六宫连续数独,考查学生动手动脑能力,属于中档题.四、填空题13.(7分)甲、乙两人分别从A、B两地同时出发,相向而行,在靠近B地三等分点处相遇,相遇后两人都将速度提高30千米/小时继续前进.若2小时后,当甲到达B地时,乙距A地还有400千米,那么AB两地相距860千米.【分析】确定甲乙速度的比是2:1,设乙的速度为x千米/小时,则甲的速度为2x千米/小时,利用相遇后两人都将速度提高30千米/小时继续前进,2小时后,当甲到达B地时,乙距A地还有400千米,建立方程求出x,即可求出AB的距离.【解答】解:由题意,甲乙第一次在靠近B地三等分点处相遇,可得甲乙速度的比是2:1,设乙的速度为x千米/小时,则甲的速度为2x千米/小时,相遇后两人都将速度提高30千米/小时继续前进,2小时后,当甲到达B地时,乙距A地还有400千米,则2(x+30)+400=2(2x+3)×2,解得x=,AB两地相距2(2x+30)+2(x+30)+400=860千米,故答案为860.【点评】本题主要考查了一元一次方程的应用﹣行程问题,审清题意找到等量关系是解决问题的关键.14.(7分)一个自然数恰有48个约数,并且其中有10个连续的自然数,那么这个数的最小值是2520.【分析】因为这个数中的因数中有10个连续的自然数,那么这个数最小是1、2、3、4、5、6、7、8、9、10的最小公倍数,然后再验证这个最小公倍数是不是有48个约数.如果验证不到,再求2、3、4、5、6、7、8、9、10、11的最小公倍数,就这样去尝试.【解答】解:因为10=2×5,9=3×3,8=4×2,所以这10个数的最小公倍数,也就是7、8、9、10的最小公倍数.7、8的最小公倍数是56,9、10的最小公倍数是90,56和90的最小公倍数是2520.将2520分解质因数得23×32×5×7,所以它的因数个数是(3+1)×(2+1)×(1+1)×(1+1)=48个故此题填2520.【点评】此题考查是求公倍数的方法,以及如何去求约数的个数,采用的是假设验证的解题策略.15.(7分)在小于2015的自然数中,可以表示成5个连续自然数的和,又可以表示成6个连续自然数的和,还可以表示成连续7个自然数的和,这样的数共有10个.【分析】将连续的5、6、7个自然数求和,找出“5个连续自然数的和,一定是5的倍数;7个连续自然数的和,一定是7的倍数;6个连续自然数的和,一定是3的奇数倍”,找出5、3、7的最小公倍数,再找出在小于2015的自然数中,是105的奇数倍的数的个数即可.【解答】解:设连续的5个自然数分别为n、n+1、n+2、n+3、n+4,∴连续的5个自然数的和为n+(n+1)+(n+2)+(n+3)+(n+4)=5n+10=5(n+2),∴5个连续自然数的和,一定是5的倍数;同理,可得出7个连续自然数的和,一定是7的倍数.设连续的6个自然数分别为n、n+1、n+2、n+3、n+4、n+5,∴6个连续自然数的和为n+(n+1)+(n+2)+(n+3)+(n+4)+(n+5)=6n+15=3(2n+5),∴6个连续自然数的和,一定是3的奇数倍.∵5、3、7的最小公倍数为:5×3×7=105,105是3的奇数倍,∴2015÷105=19…20,∴在小于2015的自然数中,是105的奇数倍的数一共有(19+1)÷2=10个.故答案为:10.【点评】本题考查了数字问题以及最小公倍数,通过自然数求和找出“5个连续自然数的和,一定是5的倍数;7个连续自然数的和,一定是7的倍数;6个连续自然数的和,一定是3的奇数倍”是解题的关键.16.(7分)对一个大于1的自然数进行如下操作:如果是偶数则除以2,如果是奇数则先减去1再除以2,如此进行直到得数为1,操作停止.那么,所有经过3次操作结果为1的数中,最大的数是15.【分析】分析与解答过程如下.【解答】从1开始向前倒推,寻求原数的最大值;若发现上一步是偶数,则须本数×2;若上一步是奇数,则须本数×2+1;显然,每次向前推出的奇数可使原数更大,倒推过程为:1→3→7→15所以,15是原数的可能达到的最大值.故:填15.【点评】利用数论、倒推方法,研究奇偶性.五、解答题17.(8分)计算:(1)2.015×128+20.15×76+201×1.12(2)++.【分析】(1)确定2.015为公因数,然后根据乘法的分配律简算即可.(2)把拆分为﹣,然后简算即可.【解答】解:(1)2.015×128+20.15×76+201×1.12=2.015×128+2.015×760+2.015×112=2.015×(128+760+112)=2.015×1000=2015(2)++=++﹣=++=+=【点评】此题重点考查了学生对运算定律的掌握与运用情况,要结合数据的特征,灵活选择简算方法.18.(8分)解下列方程(组),并用方程(组),解应用题,写出简要解题过程:(1)解方程:=3﹣.(2)某班有45名同学,其中有5名男生和女生的参加了数学竞赛,剩下的男女生人数恰好相等,这个班有多少名男生?【分析】(1)利用一元一次方程的求解步骤,即可解方程;(2)设原来男生有x人,离开5人还剩下(x﹣5)人;女生原来有45﹣x人,走了女生的还剩下(1﹣)(45﹣x)人,根据剩下的男女生人数相等列出方程.【解答】解:(1)=3﹣,去分母:5(x+8)=45﹣3(x﹣1)去括号:5x+40=45﹣3x+3,移项、合并同类项:8x=8两边同除以8:x=1;(2)设原来男生有x人,由题意得:(1﹣)(45﹣x)=x﹣5,x=21;答:这个班原来有男生21人.【点评】解决本题先设出数据,把剩下的男女生的人数分别表示出来,再根据等量关系列出方程求解.19.(15分)如图所示,△ABC的面积是210,D、E分别是BC、AC的中点,F 分别是AB的四等分点(靠近B 点).(1)求△ABE的面积是多少?(2)求BP:PE(3)求△PMN的面积是多少?【分析】(1)利用三角形中线的性质即可解决问题;(2)根据PB :PE=S △ABD :S △ADE ,计算即可;(3)根据S 阴=S △EDF ﹣S △EFN ﹣S △DFM ﹣S △EDP 计算即可;【解答】解:(1)∵AE=EC∴S △ABE :S △ABC =1:2,∴==105;(2)如图,连接DE .∵PB :PE=S △ABD :S △ADE =:•S △ABC =2:1,∴BP :PE=2:1;(3)连接EF 、DF .∵S △DEF =S △ABC ﹣S △AEF ﹣S △DBF ﹣S △DEC =S △ABC ﹣S △ABC ﹣S △ABC ﹣S △ABC =S △ABC , 又∵FN :CN=S △FBE :S △BCE =1:4,∴S △EFN =S △ABC ,∵FM :CM=S △ADF :S △ADC =3:4,∴S △FDM =S △ABC ,∵PA :PD=S △ABE :S △BDE =2:1,∴S △PED =S △ABC ,∴S 阴=S △EDF ﹣S △EFN ﹣S △DFM ﹣S △EDP =(﹣﹣﹣)S △ABC =8.【点评】本题考查三角形的面积、掌握比例模型的解决问题的关键,学会添加常用辅助线,构造比例模型解决问题.20.(13分)定义符号“|a|”,称做a的绝对值.绝对值的几何意义是:如图所示,|a|表示数a的点到原点(图中的0)的距离:距离不能小于0.如:3的到原点距离是3,所以3的绝对值是3;同样﹣3的绝对值也是3;(1)若|a|=1,|b|=2,且b>a>0,则a+b3.(2)若|3a﹣b﹣5|+|b+c﹣9|+|a+c﹣8|=0,则a+b+c=12.【分析】(1)由|a|=1,|b|=2,且b>a>0,推出a和b都是正数,且a=1,b=2(2)|3a﹣b﹣5|+|b+c﹣9|+|a+c﹣8|=0,说明3a﹣b﹣5=0,b+c﹣9=0,a+c﹣8=0【解答】解:(1)a+b=1+2=3(2)3a﹣b﹣5=0①b+c﹣9=0②a+c﹣8=0③①+②得3a+c﹣14=03a+c=14④④﹣③得2a+8=14a=3由②得b+c=9所以a+b+c=3+9=12【点评】这题的关键是一个数的绝对值大于或等于0,第(2)题只有三部分都得0等式才成立.21.(18分)三角形的内角和是不变的,即在任意三角形ABC中,∠A+∠B+∠C=180°.利用三角形内角和是180度这一性质,可以推出一个非常重要的结论:三角形的一个外角等于和它不相邻的两个内角的和,如图所示:∠A+∠B=∠ACD.根据以上内容,解答下面的题目:(1)已知在三角形ABC 中,∠C=80°,∠A﹣∠B=20°,那么∠B的度数是D.A.60° B.30° C.20° D.40°(2)如图2,P是三角形ABC内一点,比较∠BPC与∠A的大小并简单说明理由.(3)如图3,∠1=27.5°,∠2=95°,3=38.5°,那么∠4=19°.【分析】利用“三角形内角和是180度、三角形的一个外角等于和它不相邻的两个内角的和”这2个性质和结论求解即可.【解答】(1)角形ABC 中,∠C=80°,则:∠A+∠B=180°﹣80°=100°,而∠A﹣∠B=20°,则:∠B=40°,故选D.(2)∠BPC=180°﹣∠PBC﹣∠PCB,∠A=180°﹣∠ABC﹣∠ACB;而∠PBC<∠ABC,∠PCB<∠ACB,故∠BPC>∠A.(3)∠CDB=∠1+∠4,∠CDB=180°﹣∠2﹣∠3,则∠1+∠4=180°﹣∠2﹣∠3,故:∠4=180°﹣(∠1+∠2+∠3)=180°﹣(27.5°+95°+38.5°)=19°.【点评】根据“三角形的一个外角等于和它不相邻的两个内角的和”和“三角形内角和是180度”,逐一求解即可.第21页(共21页)。
