问：介绍一种小物品（如：闹钟，笔盒，笔记本等），介绍什么好？你所介绍的物品又有什么词语，句子可以用？

如果真有一个人完全像我,看她就像拥有另一个自己,会是一件多么可爱的事!这是儿童文学 《世界上的另一个我》中的一句话.
故事中讲了女孩姚果粒发现,家中小猫豆沙在窗台和一只一模一样的流浪猫对视.没想到这种事眨眼也降临到她头上——一个古怪摄影师叔叔“不是双胞胎”的摄影计划,让她撞上和自己长得一模一样的毫无血缘关系的女孩蓝泰格.两个“形式”相同,“内容”相反的女孩,时而冲突,讨厌对方的存在；时而忍不住好奇,彼此悄悄探究；时而又有神秘的认同感.种种变化让她们的生活起伏不定,异想天开的置换游戏更让她们发现了内心的另一面.两个女孩在一种神秘的好奇和烦恼中豁然长大.“世界上的另一个我”,让她们彼此终于拥有了一种奇异的完整感,也揭开了果粒的身世之谜,更让脱线妈妈别丹心和时装女魔头妈妈蓝蔚蓝各自解开了心结.本书离奇却美妙,悬疑却温暖,让你读来不可思议,又爱不释手.
读完这个故事,我的脑海中跳出来的一个大问号：如果我有很多个呢?有胆小的我,有笨笨的我,有不会唱歌的我,有写字写很丑的我,有爱漂亮的我,有爱跑步的我……那么会不会就有很多个另一个我：有胆大的我,有聪明的我,有唱歌很好听的我,有写字很漂亮的我,有不爱漂亮酷酷的我,有不爱跑步懒懒的我……
宇宙天地间将有无数个我,世界上是没有陌生人的,只要我够用心,每个人都有可能跟我心灵相通,我可以和所有的他们交朋友,还可以让所有的他们喜欢哦.
我还在想 ：如果世界上真的有另一个我,她会是什么样子?我哭的时候 , 她一定在笑 ；我害怕的时候 , 她一定很勇敢；我想逃避的时候,她却挺身面对；我因冬日的阴霾而彷徨,她绽放出花开的微笑.我孤独、失落、迷惘 她豁达、坚强、自信 .我掉入一句话的深渊中黯然神伤苦思冥想,她耸耸肩膀扬扬眉毛向天空挥手 ；我透过指尖的缝隙看到流逝的光阴 拼命拼命想要抓住不要让它跑掉； 她推开窗户, 享受般深深呼吸着大自然的灵气 ；我怯懦了退到了墙角根处默默细数着这个时节逃不过劫难的银杏叶, 她双手叉着裤袋晃迹于大街小巷的人群之中饶有兴致的数着人们脸上的皱纹有几毫深 ；我犹豫着说不是的, 她爽朗的笑容早已证明了一切；我心有余悸地打开属于青春的潘多拉魔盒 ,她没心没肺地哼着小曲,咬着小调儿 ；我眉头深锁看到了荒芜的土地 ,她孩童般的欣喜地看着夜晚的星空；我穿越长长长长的长廊走向对面 , 她正在转身的刹那 ；我认出了她 ,她看到了我 —— 于是我和她相遇了.于是时光重叠 ,年华倒转 .

This semester we will have a new teacher. His name is Mr. Wilson, and he is 25 years old now. Mr. Wilson is Australian, and likes reading playing football and watching movies very mcuh. He will teach us English and math. He is of medium height, has curly blond hair, and wears a pair of blue glasses. Mr. Wilson is smart and very popular among students.

The Golden Ratio can occur anywhere.In plain English we can say that two lengths are in the Golden proportion if the ratio of the shorter lenth to the longer length is equal to the ratio of the longer length to the sum of both lengths.Let S=shorter length and L=longer length.Then using mathematical notation:S/L = L/(S+L).We can solve this equation for S in terms of L and we find that L=S*(1+5^.5)/2 or approximately L=1.6S.(If you know how to solve the equation above by using the quadratic formula,then porve th yourself that this is true.) So this is the unique case where the two lengths are in the Golden Ratio.

煤油灯 Kerosene lamp,(在英国被广为称作石蜡灯paraffin lamp),电灯普及之前的主要照明工具,以煤油或石蜡作为燃料.
早于9世纪的巴格达,已有使用煤油灯的记载,而近代的煤油灯则于1853年由一名波兰发明家Ignacy Lukasiewicz发明.
有两种主要的煤油灯,灯芯灯"wick lamp" 和 压力灯"pressure lamp",但运作方式不同.
煤油灯 Kerosene lamp结构：
旧式煤油灯使用棉绳灯芯,其灯头通常以铜制成,而灯座和挡风用的灯筒则用玻璃制成.
灯头四周有多个爪子,旁边有一个可控制棉绳上升或下降的小齿轮.
棉绳的下方伸到灯座内,灯头有螺丝绞与灯座相配合,故可把灯头扭紧在灯座上.而灯座内注满煤油,棉绳便把煤油吸到绳头上.
只要用火柴点着绳头,并罩上灯筒,便完成点灯的动作.现时旧式煤油灯已几近绝迹.

奇数间隔2,所以7户人家的门牌号可以表示为
X-6, X-4, X-2,X,X+2,X+4,X+6
7家之和=7X=259 可得 X=37
所以中位数是37,每家门牌号依次是 31,33,35,37,39,41,43

x^这个是平方的意思把?
那么就是先化简.y=1+（-3/x^+1）因为x^+1的值域为1到正无穷,所以-3/x^+1值域为【-3,0）,所以y值域为【-2,1）
方法有1、直接观察法； 2、配方法 3、换元法； 4、判别式法； 5、单调性法； 6、反函数法； 7、一一映射法； 8、数形结合法； 9,函数的有界性法； 10,基本不等式法； 11,多种方法综合应用.

Introduce myself
I have a happy family. My father is a worker,my mother is a teacher and I am a junior high school student.
I favorite sport is football ,when I was young I usually play it with my comates.But I haven't played it for three years,because I have too much homework.My mother always restricts my time-uot to make me study. I can't stand it .

解题思路：根据例题中的大小比较的方法，先求出2个[3/4]的积是：[9/16]；先把它与[1/2]相比较，[9/16]＞

1

2

；所以10个[9/16]的积＞10个[1/2]的积，10个[1/2]的积是[1/1024]，由此只要比较[1/1024]与[1/1089]的大小即可解决问题．

2个[3/4]的积是[9/16]；[9/16]＞
1
2；
所以10个[9/16]的积＞10个[1/2]的积，
10个[1/2]的积是[1/1024]，即20个[3/4]的连乘积＞[1/1024]；
又因为[1/1024]＞[1/1089]；
所以20个[3/4]的连乘积大于 [1/1089]．

点评：
本题考点： 比较大小．

考点点评： 此题考查了较大的分数的比较方法的灵活应用，这里找出10个[1/2]的乘积作为中间比较数，是解决本题的关键．

氙气大灯
根据统计,人们驾车发生事故的时间,几乎 60% 以上是集中在夜间及天候不良的情况中,这都是因为在这些时间的驾车视线通常较差,驾驶人就必须花费较多眼力及体力来聚精会神观看路面,间接造成疲劳及注意力分散,当然驾车发生意外的比例也会跟着水涨船高!
氙气大灯——全称是HID气体放电灯,它的发光原理是利用正负电刺激氙气（XENON）与稀有金属化学反应发光.所以您会发现在HID的灯管内还有一颗小小的玻璃球,这其中就充满了氙气及少许稀有金属,只要用电流去刺激它们进行化学反应,两者就会发出高达4000K以上色温的光芒,这是传统卤素灯所难以望其项背的光度,此外,由于氙气分子的活动能力会随着使用时间的加长而越趋活泼,因此氙气大灯会越用越亮!
通常计算亮度的单位称之为“流明度（Lu?men）”,氙气大灯可以输出高达3200Lumen的亮度,而一般卤素灯泡最多也只能产生1000Lumen上下的亮度,由此看出氙气大灯的亮度是传统卤素灯三倍.
根据一项研究显示,就算品质再高的卤素灯泡,最多也只能连续使用400小时；而利用气体发光的氙气灯泡,最少都有2500小时的使用寿命,也就是说您在正常的用车条件下,一组HID气体放电灯足够您用上6年多!

First Flight第一次坐飞机
Mr.Johnson had never been up in an aerophane before and he had read a lot about air accidents,so one day when a friend offered to take him for a ride in his own small phane,Mr.Johnson was very worried about accepting.Finally,however,his friend persuaded him that it was very safe,and Mr.Johnson boarded the plane.
约翰逊先生从前未乘过飞机,他读过许多关于飞行事故的报道.所以,有一天一位朋友邀请他乘自己的小飞机飞行时,约翰逊先生非常担心,不敢接受.不过,由于朋友不断保证说飞行是很安全的,约翰逊先生终于被说服了,登上了飞机.
His friend started the engine and began to taxi onto the runway of the airport.Mr.Johnson had heard that the most dangerous part of a flight were the take-off and the landing,so he was extremely frightened and closed his eyes.
他的朋友启动引擎开始在机场跑道上滑行.约翰逊先生听说飞行中最危险的是起飞与降落,所以他吓得紧闭双眼.
After a minute or two he opened them again,looked out of the window of the plane,and said to his friend,"Look at those people down there.They look as small as ants,don't they?"
过了一两分钟,他睁开双眼朝窗外望去,接着对朋友说道：“看下面那些人,他们看起来就象蚂蚁一样小,是不是?”
"Those are ants," answered his friend."We're still on the ground." “那些就是蚂蚁,”他的朋友答道,“我们还在地面!"

地球是我们的家园,我们必须照顾好它我们应该使减少污染,如我们所知大家在北美的垃圾进行1000公斤.
