33、10P4 ZH6Z4K2L7A4第6页共 7页2014 年广东省佛山市华英学校小升初数学试卷参考答案一选择题本大题包含6 小题，每题 3 分，共 18分1C；2A；3B；4B；5C；6B；二、判断题：对的打“”，错的打“”。每题 2 分7；8；9；10；11；三、填空题每题4分，共 28分122360；131；141080；15140；16；17800；1814；四、计算题第1 题每空 2 分，2-3 题每题 4 分，共 20 分19；81；1.75；2464；20259，521；21=68；五、解决问题每题8 分，共 24 分22 300，9，50a；皮筋伸长的长度，正比；解：设这袋苹果的质

34、量为a克，则43=8+50a解得 a=1750；答：这袋苹果的质量为1750 克23要使叠放一起后外表积最小，应将两个海绵中最大的一面叠合，且使叠合后最大的一面触地，示意图如下。遮罩的最小面积为：1 5 7.9m2；24解：1设甲、乙的相同速度为米/分，则据第一次两人离十字路口中心的距离相等得1500-5=5+5解得=100 此时甲、乙距十字路口中心均为1500-5=1000米这时甲到路口中心需要的时间是：1000(1002)=5(分)故设再过 y 分钟两人离十字路口距离又相等，有y-5 1002=1000+100y 解之得 y=20答：再过 20分钟两人离十字路口距离又相等，文档编码:CG2
