2024-2025学年江苏省无锡市小学五年级数学上册期中素质自测试卷及答案

2024-2025学年江苏省无锡市小学五年级数学上册期中素质自测试卷班级:________________ 学号:________________ 姓名:______________一、单选题(每题3分)1.一个数的因数的个数是()。

A. 无限的B. 有限的C. 有时无限有时有限答案:B2.0.5×8和8×0.5两个算式相比,()。

A. 结果相同,意义不同B. 结果相同,意义也相同C. 结果和意义都不同答案:A3.下列各数中,与0.5相等的数是()。

A. 0.50B. 0.05C. 5.0答案:A4.一个三角形的底是10cm,高是8cm,它的面积是()。

A. 40cmB. 80cm²C. 40cm²答案:C5.一个平行四边形的底是12厘米,高是底的2倍,它的面积是()。

A. 24平方厘米B. 144平方厘米C. 288平方厘米答案:B二、多选题(每题4分)1.下列说法中,正确的有()A. 平行四边形的对边相等B. 两个梯形一定能拼成一个平行四边形C. 两个底角为45°的等腰三角形一定是锐角三角形D. 圆的周长是直径的π倍答案:A、D解析:A项,平行四边形的性质是对边相等,所以A项正确;B项,只有当两个梯形完全相同时,它们才能拼成一个平行四边形,所以B项错误;C项,等腰三角形的两个底角为45°,则顶角为90°,所以它是直角三角形,不是锐角三角形,C 项错误;D项,圆的周长C和直径d之间的关系为C = πd,所以D项正确。

2.在下面的图形中,对称轴最多的是()A. 等腰三角形B. 长方形C. 正方形D. 圆答案:C、D解析:等腰三角形有一条对称轴(底边上的高所在的直线),长方形有两条对称轴(对边中点的连线),正方形有四条对称轴(两条对角线及两组对边中点的连线),圆有无数条对称轴(经过圆心的任意直线)。

因此,对称轴最多的是正方形和圆。

1折半查找的判定树
2查找54,依次比较哪些元素30,63,42,54元素
3查找90,依次比较哪些元素30,63,87,95元素
4查找概率相等,求查找成功的平均查找长度
答:求ASL之前,需要统计每个元素的查找次数。判定树的前3层共查找1+2×2+4×3=17次;但最后一层未满,不能用8×4,只能用5×4=20次,所以ASL=1/12(17+20)=37/12≈3.08
③希尔排序增量(5,3,1)
{12, 2, 16, 30, 28, 10, 16*, 20, 6, 18}
第一轮:增量为5:
12,2,16,30, 28,10,16*,20,6, 18
由下图更清楚的看到:
12,10
2,16*
16,20
30,6
28, 18
颜色相同的进行比较大小,按照左小又大的原则交换
第8章
T1用以下序列排序
{12, 2, 16, 30, 28, 10, 16*, 20, 6, 18}
①直接插入排序
选一项为基数,每加入一向,进行比较
(12)2, 16, 30, 28, 10, 16*, 20, 6, 18
(2, 12) 16, 30, 28, 10, 16*, 20, 6, 18
2,12,16,30,10,28,16*,20,6,18第二轮
2,10,12,16,16*,20,28,30,6,18第三轮
2,6,10,12,16,16*,18,20,28,30,
(2, 12, 16), 30, 28, 10, 16*, 20, 6, 18
(2, 12, 16, 30),28, 10, 16*, 20, 6, 18
(2, 12, 16, 28, 30),10, 16*, 20, 6, 18
(2,10, 12, 16, 28, 30),16*, 20, 6, 18
如此类推
(2, 6, 10, 12, 16, 16*, 18, 20, 28, 30)
②折半插入排序
在进行每轮后产生的结果与直接插入排序是一样的
(12)2, 16, 30, 28, 10, 16*, 20, 6, 18
(2, 12) 16, 30, 28, 10, 16*, 20, 6, 18
(2, 12, 16), 30, 28, 10, 16*, 20, 6, 18
2,12,16,28,10,16*,20,6,18,30
2,12,16,10,16*,20,6,18,28,30
2,12,10,16,16*,6,18,20,28,30
2,12,10,16,6,16*,18,20,28,30
2,12,10,16,6,16*,18,20,28,30
2,10,6,12,16,16*,18,20,28,30
2,6,10,12,16,16*,18,20,28,30
⑦堆排序
⑧二路归并排序
序列项:两两一组,判断大小;
序列间:两两合并,归并大小
{12, 2, 16, 30, 28, 10, 16*, 20, 6, 18}
12, 2,16, 30,28, 10,16*, 20,6, 18分组
2,1216,30,10,28,16*,20,6,18第一轮
2,6,10,12,16,16*,18,20,28,30
2,6,10,12,16,16*,18,20,28,30
⑤快速排序(不好掌握)
先选定一个基数,然后从右向左找第一个比基数小的,交换
已选定基数不变,然后从左往右找第一个比基数大的,交换
直到遍历完成
⑥简单选择排序
每轮挑出一个最小的(感觉像冒泡排序的逆过程)
{12, 2, 16, 30, 28, 10, 16*, 20, 6, 18}
(偷懒省去了后半部分序列)
2,
2,6
2,6,10
2,6,10,12,
2,6,10,12,16
2,6,10,12,16,16*
2,6,10,12,16,16*,18
2,6,10,12,16,16*,18,20
2,6,10,12,16,16*,18,20,28
因此,第一轮结果为:
10, 2, 16, 6, 18,12, 16*, 20, 30, 28
第二轮:增量为3:
利用上一轮的方法可以很快得出:
第二轮结果为:
6,2,12,10,18,16,16*,18,20,28,30
第三轮:
2,6,10,12,16,16*,,18,20,28,30
④冒泡排序
每一轮筛选出最大的一项直至排序完成
(2, 12, 16, 30), 16, 28, 30),10, 16*, 20, 6, 18
(2,10, 12, 16, 28, 30),16*, 20, 6, 18
如此类推
(2, 6, 10, 12, 16, 16*, 18, 20, 28, 30)
