Popcorn Park is not like most zoos. It is a very special place. Workers at the zoo
care for hurt or sick animals. They return some of these animals to their natural homes.
Those animals that cannot live on their own stay at Popcorn Park Zoo.
At first this unusual place was not a zoo. It was called the Forked River Animal Care
Center. The workers there took care of lost or unwanted cats and dogs.
The change to the center began in 1977 when a raccoon(浣熊) needed help. The workers
cared for the animal. Finally it was better, but it could not care for itself. The raccoon
was allowed to live at the center.
Once people heard about the wonderful work being done at the center, they began taking
all kinds of hurt or homeless animals there. Soon the center was no longer just a home
for cats and dogs. So many animals were living at the center that it became more like
a zoo. It was time for a new name.
Popcorn Park Zoo got its funny name because many of the animals there like to eat
popcorn （爆米花）made without oil or salt. Also the popcorn is sold at the zoo to help
make money to care for the animals. People buy the popcorn to feed the animals as a treat. Popcorn Park Zoo now takes care of more than 200 kinds of animals. All the animals at the zoo get lots of care and love. ( )39. Workers at the zoo look after ______. A. only homeless cats and dogs B. hurt or sick animals

江苏省沭阳县修远中学2020-2021学年九年级上学期第四次月考数学试题(解析版)
2020—2021学年度第一学期第四次阶段测试 初三数学试题 一、单选题 1. 若a、b 是一元二次方程x2+3x -6＝0 的两个不相等的根，则a2﹣3b 的值是（） A. -3 B. 3 C. ﹣15 D. 15 【答案】D 【解析】 【分析】 根据根与系数的关系可得a+b=﹣3，根据一元二次方程的解的定义可得a2=﹣3a+6，然后代入变形、求值即可． 【详解】∵a、b是一元二次方程x2+3x﹣6=0的两个不相等的根，∴a+b=﹣3，a2+3a﹣6=0，即a2=﹣3a+6，则a2﹣3b=﹣3a+6﹣3b=﹣3（a+b）+6=﹣3×（﹣3）+6=9+6=15． 故选D． 【点睛】本题考查了根与系数的关系及一元二次方程的解，难度适中，关键掌握用根与系数的关系与代数式变形相结合进行解题． 2. 下列说法正确的是（） A. 三点确定一个圆 B. 圆的切线垂直于过切点的半径 C. 平分弦的直径垂直于弦，并且平分弦所对的两条弧 D. 长度相等的弧是等弧 【答案】B 【解析】 【分析】 根据圆的切线，弦和弧的概念逐一判断即可． 【详解】不共线的三点确定一个圆，故A选项错误； 圆的切线垂直于过切点的半径，故B选项正确； 平分弦（非直径）的直径垂直于弦，并且平分弦所对的两条弧，故C选项错误； 能够互相重合的弧为等弧，故D选项错误；
故选B ． 【点睛】本题考查了圆的基础知识，熟练的掌握圆的相关基础定义和性质是解决本题的关键． 3. 若1x ，2x ，3x ，4x 的平均数为4，5x ，6x ，7x ，???，10x 的平均数为6，则1x ，2x ，???，10x 的平均数为（ ） A. 5 B. 4.8 C. 5.2 D. 8 【答案】C 【解析】 【分析】 由平均数公式，计算一组数据和另一组数据的和，再由平均数公式，即可得到所求值． 【详解】解：一组数据x 1，x 2，x 3，x 4的平均数为4， 可得x 1＋x 2＋x 3＋x 4＝4× 4＝16， 一组数据x 5，x 6，x 7，x 8，x 9，x 10的平均数为6， 可得x 5＋x 6＋x 7＋x 8＋x 9＋x 10＝6×6=36， 则x 1＋x 2＋…＋x 9＋x 10＝16＋36＝52， 可得数据x 1，x 2，x 3，x 4，x 5，x 6，x 7，x 8，x 9，x 10的 平均数为 52 10 ＝5.2， 故选：C ． 【点睛】本题考查一组数据的平均数的计算，正确运用公式和变形是解题的关键． 4. 如图，在3×3的方格中，A ，B ，C ，D ，E ，F 分别位于格点上，从C ，D ，E ，F 四点中任意取一点，与点A ，B 为顶点作三角形，则所作三角形为等腰三角形的概率是（ ） A. 1 B. 14 C. 12 D. 34 【答案】D 【解析】 【分析】 根据从C 、D 、E 、F 四个点中任意取一点，一共有4种可能，选取D 、C 、F 时，所作三角形是等腰三角形，
