中学生学习报人教版数学八年级上期中测试答案
1、把200千米的水引到城市中来,这个任务交给了甲,乙两个施工队,工期50天,甲,乙两队合作了30天后,乙队因另有任务需离开10天,于是甲队加快速度,每天多修0.6千米,10天后乙队回来,为了保证工期,甲队速度不变,乙队每天比原来多修0.4千米,结果如期完成。
问:甲乙两队原计划各修多少千米?解:设甲乙原来的速度每天各修a千米,b千米
根据题意
(a+b)×50=200(1)
10×(a+0.6)+40a+30b+10×(b+0.4)=200(2)
化简
a+b=4(3)
a+0.6+4a+3b+b+0.4=20
5a+4b=19(4)
(4)-(3)×4
a=19-4×4=3千米
b=4-3=1千米
甲每天修3千米,乙每天修1千米
甲原计划修3×50=150千米
乙原计划修1×50=50千米

4.解:解:设方程的解为x,则有3x+2=2x+5,化简得x=3,即方程的解为x=3。
第二章一元二次方程1.解:解:设方程的解为x,则有x^2-2x-3=0,设其因式分解为(x-a)(x-b),则有a+b=-2,ab=-3,解得a=3,b=-1,即方程的解为x=3, -1。
2.解:解:设方程的解为x,则有x^2+2x-3=0,设其因式分解为(x-a)(x-b),则有a+b=2,ab=-3,解得a=-1,b=3,即方程的解为x=-1, 3。

Frank Mother's Day Mothcr's Day is a celebration to honor the mother of the family, motherhood and the influence【影响) of mothers in society,
Mother's Day was first celebratcd in 1908, when Anna Jarvis held a memorial for her mother in Gratton, West Virginia. Her campaign (运 动) to make Mother' s Day a recognized holiday in the United Statcs began in 1905, the year her mother, Ann Reeves Jarvis, died. Anna Jarvis wanted to honor her mother by continuing the work shc started and to set aside a day to honor all mothers, because she believed a mother is "the person who does more for you than anyone else in the world". In 1908, the U.S. Congress rejected the proposal (提案) to make Mother ' s Day an official holiday. However, because of the efforts of Anna Jarvis, by 1911 all U.S. states observed the holiday, with some of them officially recognizing Mother ' s Day as a local holiday.

2授之以渔 掌握方法技巧 提升学习能力
语文学习方法经验分享
语文怎么学习好呢?下面给大
家分享一些语文学习的方法和经验,
希望能够对大家有所帮助,一起来看
看吧。
抓好学习环节,学习可分为四个
主要环节:预习、听课、复习、作业。
每个环节都有其特点,也有其关键。
预习:预习要养成习惯,习惯很重要,既然是习惯决不能三天打鱼两
天晒网。
预习的时间要根据实际情况
而定,可以在学习曰挤时间,也可以
在周末,还可以在节假曰。
预习要找
难点,找难点的目的是就是要攻破
它,这是预习的关键。
这能证明一个
人的能力,
同时也能培养一个人的能
力,更会磨练一个人的意志。
听课:
听课是学习时最重要的环节,会听课意味着会抓重点,能理解
老师的意图。
复习:复习要摸规律,复习的目的是把学习内容进一步巩固、掌握,
以便摸清其内在规律,在运用中举一
反三。
作业:作业要独立完成,典型的内容要反复练习,这样才能形成技能
技巧。
语法点拨——should 与ought to 的用法
1.一般说来,两者可替换,只是ought to 语气稍重。
e.g.You ought to (should) go and see Mary sometime. 你应该什么时候去看看玛丽。
The train ought to (should) have arrived at six. 火车本应该6点钟到的。
Such things ought not to be allowed. 这种事情是不允许的。
2.表示出于法令规则、行为准则、道德责任等客观情况而“应该”做某事时,一般应用ought to ,若用should 则含有个人意见,强调主观看法。
e.g.We ought to go and see Mary tomorrow, but I don’t think we will.
明天我们按理应该去看看玛丽,但是我认为我们不会去(此句不宜用should)。
3.在公告、须知或条例中,出于礼貌,常用should 。
如: e.g.You should not run alongside the swimming-pool. 不准在游泳池边奔跑。
那天,一九
那天,一九。
打开了记忆的窗。
时间将记忆轻轻重叠,覆盖了太多的尘埃,久经了时间的历练,封锁,在时间的末端,那未敢触动的乱音符,好似记忆里悠扬的歌。
岁月的列车不知开往何处,也不知道何时会停下。
人如潮来往返,故事里的我们都忘了曾扮演的角色。
某些,离开了,下了生命的这趟列车,又搭上了另一趟列车。
我相信,离别是为了再见,在现实的“意外”中相遇。
可能,人,都会相信,都会耐心守候,在我看来,时间真不算什么,它带走了本该消逝的,留下它无法带走的东西。
在时间过滤下来的,都会是最最真实而美好的吧。
至少,我认为。
昨天已成为今天的“物是人非”。
现实总爱用它的残酷去取代过往,去改变那些你本不想要改变的东西,淘汰了昨日腐朽的人事,提炼现实的意义。
有时候我们依然会站在现实中,傻傻回望,争议着那些或有或无的。
多年后的今天,我仍然相信,时间不仅会带来冲撞和阅历,而且也可以带回沉睡的友谊。
那一种无需言语来定义的快乐和幸福。
木叶上栖息着风、鸟儿和往事/编织着新一季的梦幻/原来/我们都不曾遗忘/只是将它埋得太深/我们都不曾孤单/幸运的天使一直伴随/成长的伤痛/请允许我为你分担
告诉我,你很快乐,是我最大的心愿。
只要朋友还在,我们就不会伤悲,纵使黑夜吞噬了一切,太阳明天依旧。
那天,一九,不曾断开的梦。
几只鸟儿斜掠而起,剪断四溢的忧郁,雨丝里苍翠激荡,撞击我沉郁的心情。
心随雨燕,漫溯苍穹,何时记忆的角落盛开失落的追求?
世间的事情,并不是一味执著就能进步的,新的学期,又接触了许多新的面孔,可是这么多新面孔还是未能冲破那长久笼罩在班上的“阴霾”,反而让人觉得更压抑——每天6点来到教室,一片黑压压的人群,离开时,还是一片黑压压。
其实,有点恐惧坐在后面,每当抬起头,望着前面一大片弯成“小虾米”似的背影时,竟感到有点恐怖,顾不得揉揉发涩的双眼,有赶忙低下头跟数学题“厮杀”。
读死书而不活用,是不能从中获益的。
留下一点空间容自己转身,留下一点时间让自己思考,不急不缓,不紧不松。
最喜欢去的地方就是运生楼后的小山坡,草色青青,也绿了读书人的眼。
天涯的百合为谁摇碎这淡淡的忧伤?
时光漂白了朵朵艳丽,青春的草地滚落岁月的点点滴滴。
太重视感情的人容易变得固执,可是有什么用呢,当自己毅然绝然地对他们说:“没有你们,我可以过得很好”!你们说我冷血。
可是,亲爱的,世界上有太多事是我们决定不了的,或许你们都是内敛的,所以你们才会把这段我看得很重要的友谊当看成理所当然,终是,一切成空……
回忆倒带时,我在天涯之角微伤,天空尽头,是淡淡的蓝。
才明了,留下一段空白,才能学会释怀。
我常思考一个问题:当我穿梭过走廊来往的人群,在诸多同样款式颜色乃至相同质地的校服当中,谁能够清楚第辨认出是我?
又或者,我根本不需要谁来记得。
能让自己脱离这真空的枷锁的只能是自己!
当自己学会坚强,当自己能够发光发热。
蓦然回首,任雨裹我身,回归自然,不再沉迷孤寂。
乘着神怡的诗情,旋转自己,雕刻人生!
4心灵港湾远离繁华虚无独辟润泽小径
如何克服自卑心理
正确认识自己,提高自我评价
自卑的人往往注重接受别人对他的低估评价,而不愿接受别人的高估评价.在与他人比较时,也多半喜欢拿自己的短处与他人的长处相比.越比越觉得自己不如别人,越比越泄气,自然产生自卑感.其实,我们每个人都有各自的优点和缺点.因此,有自卑心理的人,首先要正确认识自己,提高自我评价,要经常回忆自己的长处和自己经过努力做成功了的事例;要善于发现自己的优点,肯定成绩,以此激发自己的自信心,不要因为由于自己某些缺点的存在而把自己看得一无是处,不能因为一次失败而以偏概全,认为自己什么都干不了。
善于自我满足,消除自卑心理
自卑的人一般都比较敏感脆弱,经不起挫折打击.一旦遭受挫折,就很容易意志消沉,增强自卑感.因此,凡事应不怀奢望,要善于自我满足,知足常乐,无论生活,工作或学习,目标都不要定得过高,这样,就容易达到目标,避免挫折的发生.必须明白和做到:努力的目的是完成自己的既定目标,而不是为了打败别人.而每次取得的成功体验,都是对自己的一种激励,是十分有利于恢复自信心的.
坦然面对挫折,加强心理平衡
自卑的人心理防御机制多数是不健全的,自我评价认知系统多数比较偏低。
改变
你改变不了环境,但你可以改变自己;你改变不了事实,但你可以改变态度。
你改变不了过去,但你可以改变现在;你不能控制他人,但你可以掌握自己;你不能预知明天,但你可以把握今天;你不能样样顺利,但你可以事事尽心;你不能左右天气,但你可以改变心情;你不能选择容貌,但你可以展现笑容;你不能延伸生命的长度,但你可以决定生命的宽度;
换一副“眼镜”看世界,我们就会少些忧愁与烦恼,多些开心与快乐。
