这次爬山不只是一次户外锻炼，而是接触大自然的机会。（求英文翻译，尽量简单点）

when i prepared this duty,looking at the photos ,i found that i really put on a litttle weight.
finally,i decided to tell about this photo,bacause it meant a lot for me.
it happened four years ago.one day,8 girls including me and 7 boys were ready to take a picnic.my parents went with us too,for something took place a few days before.this picnic impressed me most,although we had done many times.well,we went to open wasted land instead of a picnic.
first,the place we went to is called Biwenquan,we can go to the spa or play on the hills.there were all kinds of trees,it was cool.if you were not tired,you can go to the top of the hill within one hour.there were pure water which float from the bamboo tube,it was very sweet.as far as i know,the old people will take some water from the hill top home after they finishes the morning exercise.
i brought a lot of food,but we changed the routine and went to the hill near to Biwenquan.this hill is not that hight.it looked like few people came here.there was no available road later,however,we still continue to climb.it was winter,no need to worry about snakes.trees became fewer and grass more and more,it took us a lot of time and energy,sometimes we got hurt by the wild grass.i omitted a lot happenning in the middle.at last,we were so tired that we decided to go down.but we open the wasted hill,which is meaningful.in another word," i openned the hill,if you wanna go through this hill,please leave the money“
and my father said," why didn't you go on the bright road,it was time-consuming to take the mule path"

（1）由题意得
c=1 4a－2b＋c=0 ﹣b／2a=0
∴a=﹣1／4 b＝0 c＝1
y=﹣1／4x²＋1
(2)设P（X1,y1﹚
半径PO²=X1²＋y1² P到直线的距离为d²=(2－y1)²
(2－y1)²=y1²－4y1＋4
d²－PO²=－4y1＋4－X1²=－4×﹙﹣1／4X1²＋1﹚＋4－X1²=0
∴圆与L相切

这次活动真有意思
我参加过许多活动,但最有趣的还是“添嘴巴”的游戏.有一次,我们上活动课,老师笑眯眯地对我们说：“今天,我们做‘添嘴巴’的游戏好吗?”老师的话音刚落,教室里就响起了震耳欲聋的掌声,同学们拖长声音说：“好——!”
老师先把我们分成两个组.然后,老师拿着粉笔在黑板的左右两边各画了一个人头,人头的样儿倒画得不错,可惜没有嘴巴.看了这个人头,我想：这大概就是“添嘴巴”这名称的来历吧!最后,老师简单讲了游戏的玩法：两个组各派一个同学上去,交叉给另一组“添嘴巴”的人蒙眼睛,每个同学添完以后,集体评比.然后擦掉,下一个同学又再添,依次类推.
游戏开始了,每个同学都兴致勃勃的上去“添嘴巴”.但是,有的同学添到了鼻梁上,有的添到了额头上,还有的同学,走出了教室,怎么也找不到黑板,逗得大家哈哈大笑.
轮到我了,我又兴奋又紧张地走到讲台上,眼睛被蒙上以后,眼前一片黑暗,什么也看不见.我拿着粉笔,摸索着走到黑板面前；东一摸,西一摸,似乎哪儿都是一样的.过了好一会儿,我才把“嘴巴”添上去.刚添完,同学们就哈哈大笑起来.我赶紧解下毛巾一看：原来,我把嘴巴添到了眼睛上.自己也不由自主的大笑起来.
在一阵阵欢笑声中,游戏很快就结束了.但大部分同学都添错了位置,只有几个同学添得好些.老师说：“从活动可以看出,我们的眼睛是多么重要.如果没有眼睛,多艰难啊!我们一定要时时注意保护自己的眼睛.如果到双目明的人,一定要主动帮助一下.”
“叮铃铃——”下课铃响了.同学们还意犹未尽,大家都说：“这次活动真有意思,我们不仅玩得高兴,还懂得了一定的道理.”

Barbie in the "Barbie in the 12 Dancing Princesses"play the Genevieve,bring many amazing Ballet,and set foot on the fantasy adventure.
Genevieve princess one day and her 11 ballet Princess sisters,find a mysterious tunnel,to a can dream come true magic world,but at this time their father Facing to lost the throne‘s danger.Genevieve princess will and her sisters make concerted efforts,help their father,and find precious family affections,will to overcome all difficulties.

答案B
本题考查的是一元一次方程的应用.
设盈利的进价为x元.则（1+20%）x=60解得x=50故盈利为10元.
设亏损的进价为y元.则（1-20%）x=60解得y=45故亏损为15元.
综上亏损15-10=5元.
故选择B.

解题思路：实际售价=进价×（1+40%）×60%，和进价相比即可．

实际售价=a×（1+40%）×60%=0.84a，
0.84a＜a，
∴亏了．

点评：
本题考点： 列代数式．

考点点评： 考查列代数式，得到实际售价的等量关系是解决本题的关键．

人与人之间本来就有一种隔阂,但是有些人互相关爱,让他们更加亲近、和谐、还记得那一天发生的事……
那天,要数学考试.离考试还有五分钟的时候,我再一次检查我的文具盒,看看文具准备好了没.中性笔,好好地躺在文具盒中；铅笔,乖乖地趴在文具盒里内；橡皮,安静地坐在文具盒里；尺子,尺子跑哪去了?我再一次检查,嘴里还喃喃自语“中性笔,铅笔,橡皮……”还是不见尺子.我看了看表,糟了,快上课了,怎么办?怎么办呢?我着急地看了看旁边的同学,心里想“要是有人可以帮帮我就好了”----可是没有,周围的同学都在认真地准备着东西,只有我,在焦急地东张西望,六神无主的我心里想有一只调皮的小兔子在嘭嘭直跳,我心想“昨天晚上还在呀,现在怎么没了呢?难道它长翅膀飞了?那我考试怎么办?这次百分之八十的题目都要用上尺子,我该怎么办?向同学借?可是每个同学也都只带了一把呀!我越想越着急.”
就在这时,杨诗祺看见我的样子,便跑过来关心地问：“韦祎然,你怎么了?”我着急地说：“我的尺子不见了,怎么办,要是现在去买肯定来不及,更何况我又没带钱,更不要说回家拿了.怎么办呀……”她听完以后说:“原来是这么回事呀,这好办,交给我吧.”她说完回到自己座位上,把一把崭新的尺子“啪”得一声掰成了两半,我当时就愣了,傻傻地望着她,她看我傻愣在那,“扑哧”一声笑了,说：“还愣在那干什么?快拿着呀!”说着,便把手中的一截断尺子伸向了我,她看我还傻傻地看着她,便把我的手摊开,把尺子放在我的手心,我终于醒了过来,半晌,才说出一句话:“你这是干什么?”她笑着说：“‘断尺救人’呗”……就在这时,上课铃声响了起来……
事后,我一直珍藏着这把断尺,直到永远……

解题思路：设盈利衣服的进价为x元，亏损衣服的进价为y元，根据售价=进价+利润列出两关系式，表示出x与y，进而表示出x+y，即为两件衣服的进价和，与两件衣服的售价和2a比较大小即可得到商店的盈亏情况．

设盈利20%的衣服进价为x元，亏本20%的衣服进价为y元，根据题意得：
x（1+20%）=a，y（1-20%）=a，
解得x=[a/1+20%]=[5/6]a（元），y=[a/1−20%]=[5/4]a（元），
两套衣服的进价和为x+y=[5/6]a+[5/4]a=[25/12]a（元），两套衣服的售价和为2a（元），
∵[25/12]a＞2a，
则这次出售过程中商店赔[25/12]a-2a=[1/12]a（元）．

点评：
本题考点： 整式的加减．

考点点评： 此题考查了整式的加减运算，以及列代数式，属于整式加减的应用题，解此题的关键是表示出两件衣服的进价和与两件衣服的售价和，比较两者大小可得出盈亏情况．

别枉费美丽
擦去灰尘放手吧
听听别人在说什么
别人在说什么
现在别企图逃避了
为什么还要苦苦坚持?
你的坚持不会有结果
我不明白你为何要这么做
因为你的光芒开始陨落
别由着他去,你值得更多
别在他身上枉费美丽
别在苦痛中枉费美丽
当难以承受时不要放弃
别在生活里枉费美丽
很快你便能再次高飞
无论所得为何,你会明白
别枉费你的美丽
嘿
坐定来个深呼吸
瞧瞧我们何其幸运
瞧瞧我们何其幸运
这就是我们的生活
你必须心从所欲
你知道我总在不远处
挣脱你眼里的痛苦
我看到你在掩饰什么
但现在一切还不晚
因为我知道你能挽回
别怕,你能解决的
听我说
别在他身上枉费美丽
别在苦痛中枉费美丽
当难以承受时不要放弃
别在生活里枉费美丽
很快你便能再次高飞
无论所得为何,你会明白
别枉费你的美丽
当你需要人提醒时
记住,你很美,这么美
每一次酸楚,你都隐藏起来
因为你如此美丽
你很美
别在他身上枉费美丽
别在苦痛中枉费美丽
当难以承受时不要放弃
别在生活里枉费美丽
很快你便能再次高飞
无论所得为何,你会明白
别枉费你的美丽
希望可以帮到您!

The experiment would be critical for tesing the conclusion
检验数据,结论的真实性一般用test

1.设有选手x位,
[x*(x-1)]/2=45
x*(x-1)=45*2
x*x-x=90
x*x-x-90=0
(x+9)(x-10)=0
得x1=-9,x2=10（去掉负数）
所以有10位选手
2.设个位上的数为x,
则十位上的数为（9-x）
x（9-x）=[10(9-x)+x]/2
2x^2-27x+90=0
(2x-15)(x-6)=0
解得x=6或x=15/2(去掉)
所以这个两位数为36

What else can I do?
The terrible disaster caused more then 40075 inhabitants deaths and countless injured up to18:00 May 20th.The 8-day search-and- rescue efforts have put more strain on people's nerves.Many Chinese spent the agonizing week following news on TV,on net,or glancing over newspapers and on public transport during rush hours.Even strangers exchanged information on the updated death toll and the latest outcome of rescue missions; cheered for every survival narrowly escaping hell; mourned each new death; and prayed for the strong lives still trapped in the debris.But hope is dimming as time is running out.So many people lost their lives in a flash,so many happy family become destitute and homeless far and near,so many buildings collapsed without any hesitate,the earth cracked,and even worse,it rained while others try to rescue them…I can not image how sad a child will be that she or he turn out to be orphan after this earthquake.Or the old lost all her offspring in this earthquake.People begin to wonder what they can do to help those who are still suffering.
"What else can I do?" has been the question on everyone's mind since the deadly quake hit Sichuan Province.
After all,only a few warm-hearted volunteers could access "the front lines of combating disaster" considering the complicated conditions and fear of potential calamity.People can be seen everywhere lining up to make donations.In many cities,blood banks have been reported up to saturation; and volunteers wishing to donate blood have to register and wait for to be notified.More and more people are eager to be involved in the rescue and relief work that they are becoming unsatisfied with the disaster-relief efforts made outside of the quake-ravaged areas; and volunteers are descending upon the worst-hit areas in growing numbers.
It is pity that there are a lot of disasters in this Olympic year.This year,we,Chinese people,really have suffered a lot.however,we have not been defeated,instead,we've become more united and show great resolution to overcome all kinds of challenges to make our country more thriving and prosperous.
When people shout slogans "Cheer up,China!","Cheer up,Wenchuan!" after a three-minute silent tribute to quake victims,at the Tian'anmen Square in central Beijing,I know that the nightmare of the 8 days gone by will fade from the collective Chinese mind with time;and I could see the Chinese longings to rebuild a better future with dauntless perseverance and national esprit de corps !
此外短一点的话就是这篇了
may 12th,lantitude31.0,alttitude103.4,a great shock shocked all the Chinese.the 7.8 Richter degree earthquake happened to quick and silent for people to react.buildings collapsed down.mountain slided away roads.people were buried in debris.rain fell down.the world was sorry for those concerned.but it is not the end.we must save those survive in the collaps.mounts of soldiers tried hard to get to the way to the epicentre.people used their hands to chuck away darkness and despair,creating a warm hope for them.even two senior school students who had just escaped from the disaster enrolled in searching and saving.This time ,our chinese are tremendously united as one!

一天,正走在路上,手机响了,话筒里是个稚嫩的小女孩的声音：“爸爸,你快回来吧,我好想你啊!”凭直觉,我知道又是个打错的电话,因为我女儿的声音我太熟悉了..这年头发生此类事情也实在是不足为奇.我没好气的说了声：“打错了!”便挂断了电话.
接下来几天里,这个电话竟时不时地打过来,搅得我心烦,有时态度粗暴的回绝,有时干脆不接.
那天,这个电话又一次次打来,与往常不同的是,在我始终未接的情况下,那边一直在坚持不懈地拨打电话.我终于耐住性子开始接听,还是那个女孩有气无力的声音：“爸爸,你快回来吧,我好想你啊!妈妈说这个电话没打错,是你的手机号码,爸爸我好疼啊!妈妈说你工作忙,天天都是她一个人在照顾我,都累坏了,爸爸我知道你很辛苦,如果来不了,你就在电话里再亲妞妞一次好吗?”孩子天真的要求不容我拒绝,我对着话筒响响地吻了几下,就听到孩子那边断断续续的声音：“谢谢……爸爸,我好……高兴,好……幸福……”
就在我逐渐对这个打错的电话发生兴趣时,接电话的不是女孩而是一个低沉的女声：“对不起,先生,这段日子一定给您添了不少麻烦,实在对不起!我本想处理完事情就给您打电话道歉的.这孩子的命很苦,生下来就得了骨癌,她爸爸不久前又……被一场车祸夺去了生命,我实在不敢把这个消息告诉她,每天的化疗,时时的疼痛,已经把孩子折磨得够可怜的了.当疼痛最让她难以忍受的时候,她嘴里总是呼喊着以前经常鼓励她要坚强的爸爸,我实在不忍心看孩子这样,那天就随便编了个手机号码……” 我十分难过,“那孩子现在怎么样了?”我迫不及待地追问.
“妞妞已经走了,您当时一定是在电话里吻了她,因为她是微笑着走的,临走时小手里还紧紧攥着那个能听到‘爸爸’声音的手机……”
这是我找的,你可以当中心故事

Last saturday,our class managed an activity to dong river.We leave for dong river at about 8 am on our school gate.When we fininally reached the river ,everyone seemed to be absorbed in its beautiful scenery,it was all so attrative and so comfortable when we looked at them.
However,there was something uncompatable happen,that was,many visitors throwed the rubbish anywhere.It is a common sense that we shoule live in peace with environment ,once we broke down this connection ,we ought to be punished.
I suggest that there should be more dustbin in it,thus ,the visitors can throw the rubbish easier.
touching with the nature is really a wonderful thing,I look forward to visiting a another nutural scnenry.
