(10 points) The idea that some groups of people may

be more intelligent than others is one of those

hypotheses that dare not speak its name.

But Gregory Cochran is to say it anyway.

He is that bird, a scientist who works independently

any institution.

He helped popularize the idea that some diseases not

thought to have a bacterial cause were actually

infections, which aroused much controversy when it was

first suggested.

he, however, might tremble at the of what he is

about to do.

Together with another two scientists, he is

2023高二数学教案篇1

【教学目标】

知识目标：了解中心对称的概念,了解平行四边形是中心对称图形，掌握中心对称的性质。

能力目标：灵活运用中心对称的性质，会作关于已知点对称的中心对称图形。

情感目标：通过提问、讨论、动手操作等多种教学活动，树立自信，自强，自主感，由此激发学习数学的兴趣，增强学好数学的信心。

【教学重点、难点】

重点：中心对称图形的概念和性质。

难点：范例中既有新概念，分析又要仔细、透彻，是教学的难点。

关键：已知点A和点O，会作点Aˊ，使点Aˊ与点A关于点O成中心对称。

【课前准备】

叫一位剪纸爱好的学生，剪一幅类似书本第108页哪样的图案。

【教学过程】

一.复习

回顾七下学过的轴对称变换、平移变换、旋转变换、相似变换。

二.创设情境用剪好的图案，让学生欣赏。师：这剪纸有哪些变换?生：轴对称变换。师：指出对称轴。生：(能结合图案讲)。生：还有旋转变换。师：指出旋转中心、旋转的角度?生：90°、180°、270°。

三、合作学习

1、把图1、图2发给每个学生，先探索图1：同桌的两位同学，把两个正三角形重合，然后把上面的正三角形绕点O旋转180°，观察旋转180°前后原图形和像的位置情况，请学生说出发现什么?生(讨论后)：等边三角形旋转180°后所得的像与原图形不重合。

探索图形2：把两个平形四边形重合，然后把上面一个平形四边形绕点O旋转180°，学生动手后发现：平行四边形ABCD旋转180°后所得的像与原图形重合。师：为什么重合?师：作适当解释或学生自己发现：∵OA=OC，∴点A绕点O旋转180°与点C重合。同理可得，点C绕点O旋转180°与点A重合。点B绕点O旋转180°与点D重合。点D绕点O旋转180°与点B重合。

2、中心对称图形的概念：如果一个图形绕一个点旋转180°后，所得到的图形能够和原来的图形互相重合，那么这个图形叫做中心对称(pointsymmetry)图形，这个点叫对称中心。

The Power of Reading

Reading is a valuable skill that can open up a whole new world for us. Whether it's

for pleasure or for learning, reading has the ability to transport us to places we've

never been and introduce us to people and ideas we've never encountered.

Books provide a window into different cultures, historical periods, and ways of

thinking. They allow us to step outside our own lives and experiences and gain a

deeper understanding of the world. Reading can also be a source of inspiration,

encouraging us to pursue our dreams and aspire to greater things.

Moreover, reading is a great way to improve our vocabulary and language skills. It

helps us to develop a stronger grasp of grammar and sentence structure, and it

exposes us to new words and phrases that we can use in our own writing and
