The family spent a lot of time watching the penguins and learned some interesting facts about them.One of the zookeepers, Mr. Smith, approached them and began to share some information about the penguins. “Did you know that penguins are flightless birds?” he asked. “They have evolved to be excellent swimmers and are also known for their unique waddling walk. They are found in the Southern Hemisphere,mostly in Antarctica.”Tom’s mother nodded, “That’s fascinating! But how do penguins keep warm in such cold climates?”Mr. Smith smiled, “Penguins have a thick layer of blubber, which is a type of fat, under their skin. This helps to insulate them from the cold.

阳江市中心学校2018-2019学年四年级下学期数学期中模拟试卷含解析班级__________ 座号_____ 姓名__________ 分数__________一、选择题1．（2分）所有的等边三角形都是（）三角形。

A. 锐角B. 直角C. 钝角【答案】A【考点】三角形的分类【解析】【解答】180°3=60°，60°90°,三角形是锐角三角形。

故答案为：A。

【分析】等边三角形为三边相等的三角形，其三个内角相等，均为60°。

锐角三角形：三个角都是锐角的三角形叫做锐角三角形。

2．（2分）2.5+2.5-2.5+2.5=（）A. 0B. 1C. 5【答案】C【考点】小数的四则混合运算【解析】【解答】解：2.5+2.5-2.5+2.5=5-2.5+2.5=2.5+2.5=5故答案为：C【分析】要按照从左到右的顺序计算。

且不可先计算两个加法，再计算减法，这是经常出现的错误。

3．（2分）3.8+1.37+6.2+12.63=（3.8+6.2）+（1.37+12.63），应用了（）。

A. 加法交换律B. 加法交换律和结合律C. 加法结合律【答案】B【考点】小数加法运算律【解析】【解答】解：3.8+1.37+6.2+12.63=（3.8+6.2）+（1.37+12.63），应用了加法交换律和结合律；故答案为：B.【分析】有两个加数相加，交换加数的位置，和不变，这叫做加法交换律 ; 三个数相加，先把前两个数相加，再和第三个数相加，或者先把后两个数相加，再和第一个数相加，和不变，这叫做加法结合律。

本题先交换了1.37和6.2的位置，然后先算3.8与6.2的和、1.37和12.63的和，再把他们的和加起来。

因此运用了加法交换律和结合律。

4．（2分）用简便方法计算61×49＝（）A. 2989B. 1025C. 1566D. 9875【答案】A【考点】运算定律与简便运算【解析】【解答】解：61×49=（60+1）×49=60×49+1×49=2940+49=2989故答案为：A【分析】可以把61写成（60+1），然后运用乘法分配律简便计算。
