Bill performed much better when he was having fun with Joe in the school yard than he did when he was playing for the school team in front of a large crowd.“Maybe you just need to 4 more,” Joe suggested.“But I practice all the time with you!” Bill objected. He shook his head. “I just can’t play well when people are 5 me.”“You play well when I’m watching,” Joe pointed out.“That’s because I’ve known you since we were five years old,” Bill said with a smile. “I’m just not 6 playing when other people are around.”Joe nodded and understood, but he also had an idea. The next day Joe and Bill met in the school yard again to practice. After a few minutes, Joe 7 himself. “Practice without me,” Joe said to his friend. “I’ll be back in a minute.”Joe hurried through the school building, gathering together 8 he could find—two students, a math teacher, two secretaries, and a janitor.

郑州一八国际联合学校招生试卷解答一填空1.在比例尺是1:8的图纸上,甲乙两个圆的直径比是2:3,那么甲乙两个圆实际的直径比是( )。
分析与解:比的前项和后项同时扩大或缩小相同的倍数(0除外)比值不变,所以甲、乙两个圆实际的直径比还是2:32.甲、乙两个数的和是70,甲数的小数点向左移动一位就等于乙数的41,甲数是( )。
分析与解:甲数的小数点向左移动一位就等于乙数的41,也就是等于乙数的0.25,甲数的小数点不向左移动一位就等于乙数的2.5倍,甲、乙两数合起来就是2.5+1=3.5,又知道甲、乙两个数的和是70,70÷3.5=20这就是较小的乙数,那么甲数是20×2.5=503.按规律在括号里填上适当的数893、141、7912、3712、2316、121,( )。
分析与解:这些数看起来杂乱无章,经过变形后893、846、7912、7424、6948、6496,,可以发现分子的规律是后一个数是前一个数的2倍,分母的规律是依次减5.这样可知括号里的数应该是59192。
4.用15秒可以将一段木料锯成4段,用同样的速度将这根木料锯成5段需要( )秒。
分析与解:用15秒可以将一段木料锯成4段,锯成4段只需要锯3次,每次就需要5秒,用同样的速度将这根木料锯成5段需要锯4次就需要时间20秒。
5.把73化成小数,小数点后第2009位是( )。
分析与解:把73化成小数是0.128574...,每6个数一循环,2009÷6=334…5 小数点后第2009位也就是第335个循环的第五个数应该是7 。
6.分数20001997的分子和分母同时加上一个相同的自然数后得到20012000,加上的这个自然数是( )。
分析与解:原来分子分母相差3,现在相差1,说明分子分母是同时缩小了3倍,即除以3,再把分子2000乘以3的6000,这就应该是加上一个自然数后得到的数,6000-1997=4003,这就是分子分母同时加上的自然数。

一、填空题。
(共39分)1.(本题6分)已知654565⨯=⨯=⨯a b c ,(a 、b 、c 均不为0)。
则a 、b 、c 相比较最大的是( ),最小的是( )。
【答案】 c a【分析】假设式子的值为1,利用求倒数的方法计算出a 、b 、c 的值,最后比较大小即可。
【详解】假设6541565a b c ⨯=⨯=⨯=则56a =,65b =,54c =因为54>65>56,所以c >b >aa 、b 、c 相比较最大的是( c ),最小的是( a )。
【点睛】掌握用求倒数比较大小的方法是解答题目的关键。
2.(本题3分)当x =( )时,1:3x 的比值恰好是13的倒数。
【答案】1【分析】由题意可知,13的倒数是3,1:3x =3,解方程求出未知数的值即可。
【详解】根据题意列出方程: 1:3x =3 解:13x ÷=31133x ÷⨯=3×13x =1所以,当x =( 1 )时,1:3x 的比值恰好是13的倒数。
【点睛】应用等式的性质2求出方程的解是解答题目的关键。
