2所以两个锐角拼在一起可以得到一个更大的锐角,也可以得到一个钝角,不可能得到一个平角. 故选:C .【点评】此题是考查角的意义及分类.关键是掌握锐角、钝角、直角、平角的意义.4.从上午8:45到当天上午9:40,钟面上的时针需要顺时针旋转( )度. A .25B .27.5C .30【分析】时针每小时绕中心旋转=30°,每第分钟绕中心旋转=0.5°.从上午8:45到当天上午9:40是8时45分﹣9时40分=55分,用0.5°乘55,根据计算结果进行选择. 【解答】解:时针每分钟绕中心旋转=0.5°8时45分﹣9时40分=55分 0.5×55=27.5(度)答:钟面上的时针需要顺时针旋转27.5度. 故选:B .【点评】两个关键:一个是时针每份钟旋转的度数;二是从上午8:45到当天上午9:40经过了多少分钟.5.六一儿童节,小明想要过一个特殊而有意义的节日,他想要用自己的零花钱邀请爷爷奶奶和父母去公园玩,其中成人门票一张8元,儿童门票一张5元,儿童节儿童免费,请你帮小明算算需要付( )元. A .13B .23C .32 【分析】根据题意,儿童节儿童免费,只需要买爷爷奶奶和父母共4张成人票,即需要付4个8元,即8×4. 【解答】解:8×4=32(元) 答:需要付32元. 故选:C .【点评】本题关键是明确儿童节儿童免费,以及需购买的成人票的张数,然后再根据乘法的意义进行解答.6.计算9.9×4.82时,用( )比较简便. A ..乘法交换律B .乘法结合律仅供参考C.乘法分配律【分析】把9.9看成10﹣0.1,再按照乘法分配律进行简算.【解答】解:9.9×4.82=(10﹣0.1)×4.82=10×4.82﹣0.1×4.82=48.2﹣0.482=47.718故选:C.【点评】注意运算顺序和运算法则,灵活运用所学的运算定律简便计算.7.一天当中,()时候物体的影子最短.A.早晨B.正午C.傍晚【分析】根据不同时刻物体在太阳光下的影子的大小、方向的改变规律:就北半球而言,从早晨到傍晚物体的指向是:西﹣西北﹣北﹣东北﹣东,影长由长变短,再变长,解答即可.【解答】解:由分析知:一天中最短的影子是在正午,故选:B.【点评】本题考查平行投影的特点和规律.在不同时刻物体在太阳光下的影子的大小在变,方向也在改变.8.一个除法算式的被除数、除数都除以4以后,商是20,那么原来的商是()A.20B.4C.80【分析】在除法算式中,被除数和除数同时扩大或缩小相同的倍数(0除外),商不变;据此解答即可.【解答】解:根据商不变的性质可知,一个除法算式的被除数、除数都除以4以后,商是20,那么原来的商是20.故选:A.【点评】解答此题应明确:只有被除数和除数同时扩大或缩小相同的倍数(0除外),商才不变.9.在跳远比赛中,合格的标准是3.00米,明明跳出了3.12米的成绩,记作+0.12米;玲玲跳的成绩是2.95米,记作()米.A.+0.05B.﹣0.05C.2.95【分析】此题主要用正负数来表示具有意义相反的两种量:选3.00米为标准3本卷由系统自动生成,请仔细校对后使用,答案仅供参考。
记为0,超过部分为正,不足的部分为负,直接得出结论即可.【解答】解:3.00﹣2.95=0.05(米),所以在跳远比赛中,合格的标准是3.00米,明明跳出了3.12米的成绩,记作+0.12米;玲玲跳的成绩是2.95米,记作﹣0.05米;故选:B.【点评】此题首先要知道以谁为标准,规定超出标准的为正,低于标准的为负,由此用正负数解答问题.10.小娟做抛硬币实验,前199次实验结果是:正面朝上100次,反面朝上99次.请判断小娟抛第200次结果()A.面一定朝上B.正面一定朝上C.正反面都有可能朝上【分析】抛硬币实验,每次都有两种结果:正面朝上或反面朝上,抛第200次结果也是如此.【解答】解:小娟做抛硬币实验,前199次实验结果是:正面朝上100次,反面朝上99次.抛第200次结果正反面都有可能朝上.故选:C.【点评】关键明白:抛的结果与次数无关,抛每次都有正面朝上或反面朝上两种结果.二.填空题(共7小题)11.2016年“十一”黄金周,某市共接待游客589700人次,改成用“万”作单位的数可以记作58.97万人.黄金周期间实现旅游收入一亿九千五百万元,省略“亿”后面的尾数大约是2亿元.【分析】改写成用“万”作单位的数,就是在万位数的右下角点上小数点,然后把小数末尾的0去掉,再在数的后面写上“万”字;省略“亿”后面的尾数就是四舍五入到亿位,就是把亿位后的千万位上的数进行四舍五入,再在数的后面写上“亿”字.【解答】解:589700=58.97万一亿九千五百万,省略“亿”后面的尾数大约是2亿,故答案为:58.97,2.【点评】做好该题的前提是熟练掌握多位数的读写法则,准确理解“亿”级“万”级“个”级数位单位及换算.把握近似数的求解方法.4仅供参考12.一个角的两边成直线,这个角是平角,是180°.【分析】根据平角的定义:当角的两边成一条直线时,这个角是平角,平角的度数是180°,据此即可填空.【解答】解:一个角的两边成直线,这个角是平角,是180°,故答案为:平;180.【点评】抓住平角的定义即可解答.13.在横线上填上适当的数,使各式的计算结果都在300到500之间.263+ 1001810÷517×20【分析】令运算的结果就是300或500,根据加减法的互逆关系,以及乘除法的互逆关系,求出横线上数的取值范围,选择其中的一个填上即可.【解答】解:(1)30﹣263=37500﹣263=237所以横线上的数在37~237之间,可以填100;(2)1810÷300=6 (10)1810÷500=3 (310)所以横线上的数在4~6之间,可以填5;(3)300÷17=17 (11)500÷17=29 (7)所以横线上的数在18~29之间,可以填20;故答案为:100,5,20.(答案不唯一)【点评】解决本题也可以运用估算的方法求出横线上的可能性,只要运算结果的范围在300~500之间即可,答案不唯一.14.用字母表示:加法交换律是a+b=b+c;乘法结合律是a×b×c=a×(b×c).【分析】加法交换律为:两个加数交换位置,和不变.用字母表示:a+b=b+c.乘法结合律为:在乘法算式中,先乘前两个数,或先乘后两个数,积不变.用字母表示为:a×b×c=a×(b×c).【解答】解:根据加法交换律与乘法结合律的意义可知,用字母表示:加法交换律是a+b=b+c;5本卷由系统自动生成,请仔细校对后使用,答案仅供参考。
