小学四年级数学下册四则混合运算单元测试
新人教版数学四年级下册：第一单元《四则运算》测试卷(解析卷)
人教版数学四年级下册：第一单元《四则运算》测试卷（解析卷）一、单选题（共5题；共10分）1. ( 2分) 2473＋(6000－2632)= （）A. 4862B. 5841C. 4702D. 4802【答案】B【解析】2473+(6000-2632)=2473+3368=5841故答案为：B【分析】算式中含有小括号，要先算小括号里面的减法，再算小括号外面的加法。
2. ( 2分) 计算完880-229=651之后，正确的验算方法为（）。
A. 880+651B. 229+651C. 651-229【答案】B【解析】计算完880-229=651之后，正确的验算方法为229+651。
故答案为：B。
【分析】减法的验算方法为：用差加减数看等于不等于被减数，或者用被减数减去差看等于不等于减数。
3. ( 2分) 下面算式中先计算减法的是（）。
A. 24+32-24B. 20+（65-60）C. 36-（19+9）【答案】B【解析】A项中，先算加法；B项中，先算减法；C项中，先算加法，所以20+（65-60）先算减法。
故答案为：B。
【分析】在没有小括号，只有加减法的计算中，按照顺序从左往右计算即可；在有小括号的计算中，先算小括号里面的，再算小括号外面的。
4. ( 2分) 8×12÷8×12的结果是（）。
A. 1B. 144C. 64【答案】B【解析】8×12÷8×12=8÷8×12×12=12×12=144故答案为：B。
【分析】整数混合运算顺序：先算乘除，后算加减，有括号的先算括号里面的，同一级运算按从左到右的顺序依次计算，能利用加法运算律和乘法运算律进行简便运算的，就进行简便运算，据此计算即可。
5. ( 2分) 下列算式中，去掉括号后不改变结果的是（）。
A. （58＋22）×（34－19）B. 150＋（180－4×28）C. （102×5－110）÷2 【答案】B【解析】A：去括号前：（58+22）×（34-19）=80×15=1200去括号后：58+22×34-19=58+748-19=806-19=787本选项不符合要求；B：去括号前：150+（180-4×28）=150+（180-112）=150+68=218去括号后：150+180-4×28=330-112=218本选项符合要求；C：去括号前：（102×5－110）÷2=（510-110）÷2=200去括号后：102×5－110÷2=510-55=455本选项不符合要求.故答案为：B.【分析】先计算原算式，再去掉括号计算，看结果是否相等。

西师大版数学四年级下册《第1单元 四则混合运算》练习题含答案
第1单元 四则混合运算例1：先在口里填上数，再列出综合算式．分析：（1）按照先同时计算括号里面的减法，再算括号外面的乘法顺序计算即可解答；（2）按照先同时计算括号里面的减法和除法，再算括号外面的乘法顺序计算即可解答。
解答：例2： AB 两地相距940千米，一辆汽车和一辆货车同时从两地相向开出，汽车平均每小时行驶88千米，货车平均每小时行驶72千米，4小时以后，两车相距多少千米？分析：此题属于行程问题速度、时和路的关系，可以首先根据速度×时间＝路程，用两车速度之和以4，求两4小行驶的路程之和是少；后用地之间的距离两车4小时行驶的程和，求出小时后，两车相少米即。
解答：940-（88+72）×4＝940-160×4＝940-640＝300（千米）答：4小时以后，两车相距300千米。
例3：杨老师在批改作业时，发现小明抄题时丢了括号，但结果是正确的，请你给小明的算式添上括号：4+28÷4-2×3-1＝4。
分析：根据题意，错误的算式是丢了括号．只能按先乘除，再加减的运算顺序来计算， （24-18）×（350÷7） ＝6×50＝300 （480-400）×（120-98）＝80×22 ＝1760因此括号添在乘除法的两侧是毫无意义的，所添的括号要能够改变运算顺序．所以，括号应添在含有加减运算的两边。
从左往右看，在4+28两侧试添括号，计算得32，再除以4得8。
小明的算式就变为8-2×3-1＝4，等式错误；如果把括号加在8-2的两侧，计算结果大于4，只能把括号加在3-1的两侧，很容易得到：（4+28）÷4-2×（3-1）＝4。
解答：正确的算式应为：（4+28）÷4-2×（3-1）＝4例4：奥斑马和小美各有钱若干元．若小美给奥斑马10元，则奥斑马比小美多的钱是小美余下来的钱数的5倍；若奥斑马给小美10元，则他们的钱数正好相等．奥斑马和小美原来各有多少钱？分析：解答此题关键是明白“奥斑马给小美10元，二人钱数相等．可知奥斑马原来钱比小美多10×2＝20（元），”再由若小美给奥斑马10元，这时奥斑马就比小美多20+20＝40元，它恰好是小美余下钱数的5倍，就可求出小美余下的钱数，进而求出他们原有的钱数。

4.【答案】B
【解析】
二、判断题
5.【答案】错误
【解析】【解答】40÷5+3
=8+3
=11
40÷8=5；
11≠5；
故，40÷5+3≠40÷8。
故答案为：错误。
【分析】混合运算的计算要按照先乘除后加减的顺序进行计算，按运算顺序分别计算等号左右两边的算式得数，再比较大小。
6.【答案】错误
【解析】【解答】两个运算不同级，要先算除法，再算减法，原题说法错误.
【分析】根据整数四则混合运算，先相除后相乘即得下午5时刚换成红灯，到5时10分要转换的次数。
【分析】根据去小括号前后的运算顺序是否发生变化去判断，如果去小括号后的运算顺序与去小括号前的运算顺序相同，那么小括号可以去掉。如果去小括号后的运算顺序与去小括号前的运算顺序不相同，那么小括号不能去掉。根据以上分析可得答案。
三、填空题
8.【答案】650+150-240÷8
【解析】【解答】解：650与150的和就是650+150，240除以8的商就是240÷8，所以算式是650+150-240÷8。
【解析】【解答】解：36÷4＋5=14，÷7=4，14>4，所以36÷4＋5> ÷7；56÷7-4=4，3+5×4=23，4<23，所以56÷7-4<3+5×4；（6+2）×9=72，2×9+6=24，72>24，所以（6+2）×9>2×9+6；42-36÷4=33，48÷（8-2）=8，33>8，所以42-36÷4>48÷（8-2）。
