如果你上高三,这样就是相当少啦～
六年级么……不算多～要不初一会受不了的,这样会有一个过渡

根据A的纵坐标变化：-1→5
可以得知线段向上平移了6个单位
所以根据B的纵坐标变化有：2n-m+6=m+2n
根据B的横坐标变化：-2→2
可以得知线段向右平移了4个单位
所以根据A的横坐标变化有：m+6n+4=2m+5n
联立之后解得：m=3,n=-1
所以A'（1,5）,B’（2,1）
有问题可以继续追问,

　　英语作文：游览长城
　　A Trip to the Great Wall
　　Three days ago we decided to visit the Great Wall.
　　Today we met at the bus stop early in the morning. When we were
　　on the bus, we saw a lot of new buildings and new shops.Beijing was
　　taller than before, I thought.
　　It took us about two hours to get to the Great Wall. When the
　　Great Wall appeared in front of us, we couldn' , t help thinking how
　　wonderful it is! I wondered how the people in the past built it
　　without modem machines. It is said you can see it from the space.I
　　was proud of it.
　　After coming home I made up my mind to study harder than before.
　　When I grow up, I will work hard to make our country more beautiful
　　and stronger.

工作时间不仅包括了作业时间,还包括准备工作时间、结束工作时间以及法定劳动消耗时间.且午餐时间属于工作时间的胜诉的案例就是最好的证明——午餐时间属于工作时间.

分针每分钟转6°,所以转了20*6°=120°
时针每分钟0.5° ,所以转了20*0.5°=10°

一人贫苦特甚,生平虔奉吕祖,吕祖乃吕洞宾也,相传为道教之祖也.吕祖感其诚,一日忽降至其家,见其家徒四壁,不胜悯之,因伸一指,指其庭中磐石.俄顷,粲然化为黄金,曰：“汝欲之乎?” 其人再拜曰：“不欲也.” 吕祖大喜,谓：“子诚能如此,无私心也,可授以大道.” 其人曰：“不然,吾欲汝之指头也.”吕祖倏不见.
一个人特别贫穷,一生虔诚地供奉吕祖,吕祖就是吕洞宾,是道教的先祖.吕洞宾被他的诚意所感动,一天忽然从天上降到他家,看见他家十分贫穷,不禁怜悯他,于是伸出一根手指,指向他庭院中一块厚重的石头.立刻,变化成了金光闪闪的黄金,说：“你想要它吗?” 那个人拜了两次回答道：“不想要.”吕洞宾非常高兴,说：“你如果能这样,没有私心,可以传授给你成仙的真道.” 那个人说：“不是这样的,我想要你的那根手指头.” 吕洞宾忽然消失了.
1.解释：

“雨”全诗七句：
五月的雨滴/像熟透了的葡萄/一颗,一颗/落进大地的怀里!
以“熟透了的葡萄”来形容“五月的雨滴”,这是多么精彩的比喻!把雨滴写得多么可爱!这就传达了雨的重量.
下面接着三句是：
这是酿造的季节啊/到处都是密的气息/到处是酒的气息.
“酿造”、“密”、“酒”都和“葡萄”紧密地联系起来了,达到了集中地表现事物的手法.

楼上的,指出你一个错误：在8点40 不是at eight to twenty 而是twenty to nine,这里to表示距离,twenty to nine就是说离九点还有20分钟
在8点十分 at eight past ten
8点一刻 a quarter past eight; 注意,十五分钟用quarter；例如8：45,是a quarter to nine,就是说离九点还差一刻钟
在8点40 at twenty to nine
8点半 half past eight
具体时刻全用at
整点后超过三十分的用to
没有用past

好好学习,遵守校纪校规是我们每个学生应该做的,也是中华民族的优良传统美德,可是我作为当代的学生却没有好好的把它延续下来.就像很多中国青年都不知道有圣诞节,却隆重的去过圣诞节一样.我们都在无知中遗失了纪律,不明白自己的学习目的……
花自飘零水自流,一次自习,吵闹沸腾,老师您几次忧愁,此愁难消在心头,为我们的无知,特向您检讨.
首先,造成自修讲话最直接的原因是我们自我约束力差了,作业完成以后,就觉得没事可做；间接原因是我们希望做点课业之外的事情,不免相互交流,说话声音无所顾忌之时,慢慢的自习课就沸腾了.当然,这不能成为自习课不遵守纪律的理由.鲁迅先生说过……歌德也说……我们只有认真反思,寻找错误后面的深刻根源,认清问题的本质,才能给集体和自己一个交待,从而得以进步.
这次上自习讲话违背了教育管理体制,影响了老师的工作正常运转,此乃不忠,一罪也.又有辜负了伟大父母对我殷切希望,好浪费在校学习的时间,乃不孝,二罪也.更让老师您为此事殚精竭虑,伤心失望,此乃不仁,三罪也……在写此检讨之时,我深感自己的无知,后悔之极.
最后,麻烦老师及同学费时来检阅本人所做之检讨,交了这份检讨,我正处在老师对我的考验之中,……我现在彻底理解老师教育我们的苦口婆心…… 自习课不遵守纪律,决不是一件可忽略的小事!只要我们都有很好的约束能力、自主学习能力,在自习课上就没有任何借口,任何理由可以为讲话开脱!我们只有认认真真思考人生有那么多事要做,那么多的担子要挑,就没有理由在正常的自习课堂上不遵守纪律了.
为了老师辛苦地花了平常所没有的,大量时间和大量耐性给我的教导,为了不再让老师和我丧失宝贵的时间,我依循老师写了这份检讨,检讨自己的错误,由于本人第一次写检讨且加脑袋愚钝,虽用整个午休时间和不让精神休憩外加眼酸……怀着沉重复杂的心情写这篇检讨,但还是写得不好,只怿自己才蔬学浅,不能更好的运用我们深厚的汉语言文化,敬请老师谅解.
为了感谢老师的淳淳教导,我在此保证如果有一次重来的机会放在我面前,我尽我之所能克制自己,绝不让老师失望.请老师谅解我这一次的错误吧!
（以上是正文,检讨书前后的格式写全,应该足有1000字了,够你交差了!就得给我加分噢）

地球一小时标识 地球一小时（Earth Hour）是世界自然基金会（WWF）应对全球气候变化所提出的一项倡议,希望个人、社区、企业和政府在每年3月最后一个星期六20：30-21：30熄灯一小时,来表明他们对应对气候变化行动的支持.过量二氧化碳排放导致的气候变化目前已经极大地威胁到地球上人类的生存.公众只有通过改变全球民众对于二氧化碳排放的态度,才能减轻这一威胁对世界造成的影响.2011年3月26日20:30—21:30,“地球一小时”将再次引发全球城市、企业和个人的自愿参与,在这一小时内共同熄灭不必要的灯光,为地球的可持续未来祈福.

整点最简单了,8点整就是：eight o'clock
从8点零一分开始到8点30分,都可以用一个词:past.
(past表示已经过去的时间)
e.g.8:05 -- five past eight
8:15 -- quarter past eight
8:30 -- half past eight
(P.S.quarter表示四分之一,half表示一半)
从8点31分开始到8点59分,都可以用一个词：to．
(to表示即将接近的时间)
e.g.8:32 -- twenty-eight to nine.(当然咯,这样的算法比较烦,你可以直接说时间：eight thirty-two)
8:45 -- quarter to nine
8:58 -- two to nine
