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.

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。
