初二年上册数学课本复习14习题答案（P137——P139）会做的进来- -

P120/1.s=90t（t≥0）
2.二、四 0 -5 减少
4（1）Y=4X
8、设函数解析式为y=kx
由题意得{2k=-3a
ak=-6
∴a的二次方=4；
所以a=±2
又因为直线经过第四象限,所以点（2,-3a）在第四象限
所以-3a＜0；a＞0
所以a=2得k=-3
所以函数解析式为y=-3x

1．如果在平房里，突然发生地震，要迅速钻到床下、桌下，同时用被褥、枕头、脸盆等物护住头部，等地震间隙再尽快离开住房，转移到安全的地方。地震时如果房屋倒塌，应呆在床下或桌下千万不要移动，要等到地震停止再进出室外或等待救援。

依题意得
25 除 100=1/4 < 四分之一（下面也这样看）> ( 得出这中学的学生可分为四份,初一占一份)
4 - 1 = 3 （减去初一所占的一份后,初二和初三的所占比例为3/4）
3/4 * 4/3+4 = 3/7 （分量转换,得出初三的在学校里的所占比例）
3/7 - 1/4 = 5/28 （因初一比初三少40人,这里得出的是40人在学校的所占比例）
40 除 5/28 = 224（人） （得出学校一共有多少人）
224 * 1/4 = 56（人） （最后这步知道应该知道的了,不知道就去问别人）
（答自己写）
大概就这么解答,嫌步骤麻烦就自己总结写,悬赏分别忘了哈!

I like the summer holidy so much.I look forward to summer holiday every year.Last summer,I went to Shen zhen for my holiday,which is also a city of seashore like Haikou.I enjoyed having a walk along the beach after supper or having a swim in the afternoon.The sky is blue,the air is fersh.Wherever you go,You can always see the green trees,the neat grasses and the colourful flowers.They were really wonderful.Shen Zhen has a lot of tall buildings.And it is a modern city.
I am planning to spend my summer holiday on sports this year.Playing basketball is always my favourite,so some of my classmates and I will form a small team and play basketball together.Sometimes we may have a match against some other teams and I do enjoy the sense when we win the game.
If you ask me what my favourite summer holiday will be like,traveling aound the only answer.I hope that one day I could meet different people and vist different places of interest.
英语小短文,
（一）I have rested for a week.I began to feel bored.So I went out with my friends.They are my best friends in the middle school.We didn’t go to someplace special.We just saw the other.We had lunch together.While we were having lunch,we were still talking about the new school and new friends.Yes!A year later,we have grown riper.And we learned much more things and got new life.We haven’t enough time to play,to waste and to lose the way.We only have two years.Two years to go,we will get the real life which belongs to us.
（二）
I have stayed in Shanghai alone for a week.It’s time for me to go to my real home—it is in Beijing.My parents are waiting for me.Although outside is no matter how beautiful,Beijing is still my home.In fact,there is many fresh things.Like red bayberries.In the afternoon,I took a bus to Beijing.I was very unlucky that my mp3 was stolen.I was very sad.I didn’t know why thieves went to steal other’s things.Why don’t they hunt for a job?I don’t why!I hope there is no thief in our motherland.

如果AD和EF的交点是O.因为AD是角BAC的平分线,DE垂直AB,DF垂直AC,所以DE等于DF.
又因为OD等于OD,DE等于DF,角ADE等于角ADF,内角和180.,角AED等于角AFD,角EAD等于角FAD.所以三角形EOD全等于三角形EOD.所以角EOD等于角FOD,OE等于OF.又因为角EOD,角FOD的和为180度,所以DA垂直EF,所以AD垂直平分F.

其实你的基础知识已经掌握的可以了,在中考中,压轴题一般都不提倡全做完的,按照我的经验,现在你可以少做基础题,但是必须每隔几天做一回.既然老师讲的对你没用,你就可以不用认真听讲,上课的时候做点压轴题,学会总结,慢慢适应这种无头绪的感觉,等你做多了就会找到感觉的.总之,我个人建议你还是应该做一下压轴题.找找感觉.

如果是正课的话,应该是每周3到4节课,辅导课还要看你所在学校的具体安排.

别样的风采,高昂的斗志,现在向我们走来的是初二四班.他们正以整齐的步伐,饱满的精神展示着必胜的信心.这是一个拥有54名成员的大集体.这是一个团结向上,朝气蓬勃的集体；这是一个积极进取、奋勇争先的集体.54名成员,54张可爱的笑脸.诚实守信是他们的标志,踏实创新是他们的个性,虽然今天他们还是稚嫩的幼苗,但在关爱的阳光下,他们一定会成为格外耀眼的花朵.他们一直在不懈努力着,因为他们相信：是雄鹰,就该搏击长空；是蛟龙,必能畅游四海.此刻,迎着朝阳,沐浴着阳光,他们正昂首阔步,意气奋发,誓与其他各路英豪一决高下.请为我们加油,请为我们喝彩吧!

首先要清楚本学期学校的基本要求、基本教育任务及初二年级的教学任务、教学重点,再根据本校初二年级学生特点写出工作计划就比较有针对性了.要求：一是符合教学大纲；二是有针对性；三是实事求是；四是可操性强.

美,无处不在!只要你有一双能发现美的眼睛.
在公园里:郁金花,美!牡丹花,美!杜鹃花,美……可最美的还是那些双手沾满了泥土的园丁们.一滴滴汗水从他们脸颊滑落,美丽的笑容在他们脸上绽放.
在田野里:金灿灿的油菜花,多美!黄澄澄的稻谷,多美……再看那些辛勤劳作的农民伯伯们,衣着朴素,可他们就是田野里那些美的来源,丰收的喜悦在他们眼中闪耀,他们才是最美的.
在大街上,环境优美,地上没有一片落叶.每天,清扫的环卫工人的脸上、手上都是灰尘,可他们不嫌脏,不怕累,任劳任怨,他们也很美.
美还在很多地方——深夜里,在医院的手术室,灯光还亮着,忙碌的医生护士们的身影是很美的;那些看望孤儿、捐助希望小学的人,也很美;还有更多的默默努力的志愿者们……
美无所不在!可最美的还是创造美的人!

要多做题,灵活运用,还要能确定出在什么情况下用什么公式,公式有这几个
F浮=P液gV排-------给出 V排或间接给出 gV排
F浮=G空-G液-------给出这两个重力
其他公式也同上
当P液不变时F浮只与g.V排有关 g为常量,在完全浸没前P物越大V排越大,当 P物= P液时悬浮,P物大于P液时沉底,这只是技巧,大题不能这麽说还要导的

1、可列方程
n=-m-3
n=-(2/m)
解出m n的值即可
2、不一定 如果系数k异号则在不同象限 不相交 而同号则反之
3、求出有交点时两数的积 则可推出无交点时的解
或可画图像求解
