第九章 轴对称
复习二
学习目标
1．进一步认识轴对称及其基本性质． 2．进一步了解基本图形的轴对称性． 3．按要求能够作出简单平面图形经 过轴对称后的图形． 4．能利用轴对称进行一些图案设计．
一、填空题
1、把一个图形沿一条直线对折，对 折的两部分能完全重合，那么就称 轴对称图形 。 这个图形为 2、轴对称图形（或关于某条直线对 称的两个图形）对应线段 ， 相等 相等 对应角 。
答:如图
对称轴是图中的虚线． 对应点、对应线段(略)
2、已知： a⊥b，a、b相交于点O，点P为a、 b外一点． 求作：点P关于a、b的对称点M、 N．并说明：OM＝ON
解：作法：(1)过点P作PC⊥a，并延长 PC到M，使CM＝PC． (2)过点P作PD⊥b，并延长 PD到N，使DN＝PD． 则：点M、N就是点P o 关于a、b的对称点． ∵点P与点M关于直线a对称． ∴直线a是线段PM的中垂线 ∴ OP＝OM b 同理可证：OP＝ON∴ OM＝ON
中考化学知识复习第2讲：氧气的性质和用途
精品基础教育教学资料，仅供参考，需要可下载使用！中考化学知识复习二讲 氧气的性质和用途知能解读：（一）氧气的物理性质在通常状况下，氧气是无色、无味的气体，不易溶于水，在室温下，1L 水中只能溶解约30mL 氧气。
在标准状况下，氧气的密度为11.429g L -⋅，比空气略大。
氧的三态变化（101kPa ）：()()-183-218⎛⎫⎪⎝⎭−−−→−−−→←−−−←−−−℃℃无色淡蓝色淡蓝色雪花状固体气态氧液态氧固态氧 友情提示：氧气考查较多的物理性质是溶解性和密度，利用溶解性和密度可以解释一些自然现象，如高空中氧气的含量、水生动物的生存等。
知能解读：（二）氧气的化学性质氧气是一种化学性质比较活泼的气体，在一定条件下，可以跟多种物质发生化学反应，同时放出热量，氧气具有氧化性，在化学反应中提供氧，是一种常用的氧化剂。
注意：①氧气可以帮助可燃物燃烧（或支持燃烧），具有助燃性，与可燃性有本质区别。
②“剂”是一种发生某种变化的作用物质，如氧气具有氧化性，是常用的氧化剂，氧气可以提供氧从而把别的物质氧化的性质是氧气的氧化性，具有氧化性的物质可用作氧化剂。
注意：烟—大量固体小颗粒分散在空气中产生的现象；雾—大量小液滴分散在空气中产生的现象。
光—固体物质燃烧时发光；火焰—气体物质和容易汽化的物质燃烧时产生火焰。
镁条燃烧发出耀眼的强光；木炭在氧气中燃烧产生白光；蜡烛在空气中燃烧产生黄色的火焰，是石蜡汽化后的气体燃烧而产生的；铁丝燃烧没有火焰。
通过以上几个实验，我们可以看出，物质在纯氧气中燃烧比在空气中燃烧要剧烈，甚至某些不能在空气中燃烧的物质能在纯氧气中燃烧，说明氧气的化学性质比较活泼，同时也说明物质燃烧的剧烈程度与氧气浓度有关。
规律总结：上述这些反应的共同特点:①都是物质跟氧气发生的反应；②这类反应属于氧化反应；③生成物都是氧化物。
知能解读：（三）氧气的用途供给呼吸和支持燃烧。
冶炼钢铁（用纯氧炼钢，使生铁中的杂质氧化而除掉）；氧炔焰焊接和切割金属（乙炔在纯氧中燃烧，产生高温）；液氧炸药（将锯木屑等可燃固体用液氧浸泡后制成炸药）；是急救、高空飞行、潜水等的必备品。

Generally speaking, it is often used to describe anything from creative imagination, including works of poetry, drama and fiction.Then why read literature, since it is often imaginary and seems unconnected with real life?A lot of us re ad literature for enjoyment and relaxation. It’s always pleasant to read some interesting b ooks in our spare time. In a modern life full of stress, it is our common wish to read some imaginary works and look for relaxation from the stress in life.Reading literature is more than fun; it also allows us to get knowledge. As a general rule, literature represents a language of a people, and it often gives us an insight(洞察⼒) into the traditions, attitudes and values of the age in which it was written. Sometimes literature can even offer us new, creative ways to have a better understanding of the world. It introduces us to new worlds of experiences. We enjoy the comedy and the tragedy of poems, stories and plays; and we may even grow through our literary journey with books. At last we may discover meaning in literature by looking at what the writer says and how he or she says it. In some ways, we explore the human condition and analyze(分析) the way they think and feel the way they feel. Literature helps us think clearly and encourages us to open minds.So we can certainly say literature is of great importance to us.

第六讲期中复习二（阅读理解）知识归纳一、重点课文主要内容。
第1课《观潮》：描写了作者观看钱塘江大潮的盛况，展现了潮来前、潮来时、潮头过后的景象，突出了大潮的奇特、雄伟与壮观，赞美了钱塘江大潮这一奇丽壮美的自然景观。
①“那条白线很快地向我们移来，逐渐拉长，变粗，横贯江面。
再近些，只见白浪翻滚，形成一堵两丈多高的水墙。
浪潮越来越近，犹如千万匹白色战马齐头并进，浩浩荡荡地飞奔而来；那声音如同山崩地裂，好像大地都被震得颤动起来。
”赏析：主要描写潮来时壮观的声势和画面，其生动优美、富有感染力的语言把钱塘江大潮描写得有声有色、气势非凡，具有强烈的震撼力。
第3课《鸟的天堂》：记叙了作者和朋友两次经过“鸟的天堂”所看到的美丽景色，生动地描写了傍晚静态的大榕树和早晨群鸟活动的景象，表达了作者对大自然的热爱和赞美之情。
①课文第8自然段：榕树正在茂盛的时期，好像把它的全部生命力展示给我们看。
那么多的绿叶，一簇堆在另一簇上面，不留一点缝隙。
那翠绿的颜色，明亮地照耀着我们的眼睛，似乎在每一片绿叶上都有一个新的生命在颤动。
这美丽的南国的树！赏析：“一簇”说明树叶多，榕树非常茂盛。
“似乎”是作者对榕树旺盛生命力的一种感觉。
每一片叶子都很绿，都是一个鲜活的生命。
作者从富有光泽的绿叶中感受到有一种生命力在涌动，赞美了榕树充满活力的蓬勃生机。
课文最后一句：“……昨天是我的眼睛欺骗了我，那“鸟的天堂”的确是鸟的天堂啊！”赏析：加引号的鸟的天堂表示一种特定称谓，特指那棵大榕树。
最后一次没有加引号，是因为作者亲眼看到鸟儿在大榕树里生活得十分自由、幸福，真像在天堂一样，作者发自内心的认可和赞美。
第5课《古诗两首》《题西林壁》横看成岭侧成峰，远近高低各不同。
不识庐山真面目，只缘身在此山中。
这是苏轼游庐山时题在西林寺墙壁上的一首诗。
庐山景色秀美，山中奇花异木，险峰怪穴，流泉飞瀑，山亭云阁，气象万千，不可胜数。
全诗不仅是对庐山雄奇壮观、千姿百态景象的赞美，而且还蕴含着人生的哲理，内涵深刻，耐人寻味。
人教版六年级数学上册期末专项复习二比与百分数(原创)
专项复习二、比与百分数一、比考点一：比的概念：两个数的比表示两个数（ ）。
例：4:5=（ ）÷（ ）=()()=（ ）（填小数） 考点二：比值：比的（ ）除以（ ）所得的商，叫作比值。
考点三：比的基本性质：比的（ ）和（ ）同时乘或除以相同的数（0除外），（ ）不变。
例1、先化成最简整数比再求比值。
45:60 0.15:0.27352： 35.0:43 30cm ：5m例2、盐占盐水的 30%，那么盐和水的比为( )。
例3、（1）女生人数是男生人数31,则女生人数与男生人数的最简比是（ ）。
（2）女生人数比男生人数多31,则女生人数与男生人数的最简比是（ ）。
例4：甲数比乙数为 2：3，乙数比丙数为 4：5，那么甲数与丙数的比是( )。
例5、8：15 的前项增加 16，要使比值不变,后项应( )。
A 、增加16B 、增加30C 、增加 8D 、无法确定 考点三：按比分配。
例：用 120cm 的铁丝做一个长方体的框架。
长、宽、高的比是 3：2：1。
这个长方体的体积是多少？二、百分数概念：百分数表示（ ）是（ ）的百分之几。
又叫百分率或百分比。
注意：百分数表示的是分率，不能表示具体的量，故（ ）带单位。
考点一：百分数、分数、小数的互化。
例1、把下面的百分数先化成最简分数再化成小数。
5% = = 35% = = 12.5% = =例2、把下面各数化成百分数。
0.7= 1.35= 83253= 65 考点一：求一个数是另一个数的百分之几。
例1、20kg 是25kg 的（ ）%；25kg 是20kg 的（ ）%例2、检验了40个零件，有38个合格，合格率是（ ）。
考点二：求一个数的百分之几是多少。
例1、40kg 的80%是（ ）kg 。
例2：六（3）班有50人，体育达标的人数占80%，达标的有多少人？考点三：已知一个数的百分之几是多少，求这个数。
例1：（ ）kg 的80%是40kg 。
例2：一本书，看了60%，正好看了48页。
