我有一个幸福的家庭。我的家庭有三口人:爸爸、妈妈和我。
我的父母和我住在城市里。爸爸是一名工人,他的工作很辛苦。妈妈是一所中学的语文老师。她7点骑着自行车去工作,在中午她不回家,在晚上她做晚餐,食物很可口。我和弟弟是学生,每天都上语文课、数学课和英语课,那很无聊。我学习比弟弟好。我有许多朋友,课后,我和我的朋友一起玩。
我们是累的,但我们很开心。我爱我的家庭。
19世纪初,人们开始使用煤气灯(瓦斯灯),但是煤气靠管道供给,一但漏气或堵塞,非常容易出事,人们对于照明的改革,十分殷切。事实上,爱迪生为自己订定了一个不可能的任务:除了改良照明之外,还要爱迪生发明的电灯 Intheearlynineteenthcentury,peoplebegantousegas(gaslight),butthegaspipelinesupplybyaleakorblockage,veryeasytohaveanaccident,peopleforilluminationofreform,veryardent.Infact,Edisonforhimselfsetthemissionimpossible:inadditiontoimprovelighting,butalsoofThomasEdisonelectriclight 创造一套供电的系统。于是他和梦罗园的伙伴们,不眠不休的做了1600多次耐热材料和600多种植物纤维的实验,才制造出第一个炭丝灯泡,可以一次燃烧45个钟头。后来他更在这基础上不断改良制造的方法,终于推出可以点燃1200小时的竹丝灯泡。19世纪80年代中期,爱迪生的电灯事业获得了成功,这一成功比以往任何成就给他带来的声誉都大。在80年代中期以前,他很少有失误,中期以后,尽管他也取得了很大成就,但失败也是屡见不鲜的。爱迪生最不值得称赞的行为之一就是他批评交流电,说它有副作用,可能造成死亡与损伤,但他未加具体说明。所以有人说,“像他这样一个自己搞出了许多发明创造的人竟然对别人的新发明大加攻击,这是很矛盾的事。”他反对使用交流电而赞成直流电,因而在一场激烈而固执的论战中败北。在这方面,反映出了爱迪生成为名人之后渐渐滋生的顽固守旧的缺点。 Createasetofpowersupplysystem.AndheandthedreamLuoYuanbuddies,sleeplessdo1600repeatedlyheat-resistantmaterialandmorethan600plantfiberexperiment,onlyprocedthefirstcarbonwirebulb,canaburning45hours.Laterhemoreonthisbasis,themethodofcontinuousimprovementmanufacturecanignite12hoursfinallycameoutwiththeZhuSibulbs.The19thcenturythe1980s,Edisonelectriclightcareersucceeded,thissuccessthananypreviousachievementsbroughthimreputation.Inthe1980s,beforehehadlittlemistake,intermediatelater,althoughhehasmadegreatachievements,butalsocommonoccuranceoffailure.Edison'smostnotcommendableactionsisoneofhiscriticismalternatingcurrent,sayithassideeffects,likelycauseofdeathandinjury,buthedidnotadddetails.Sosomebodysaid,"ashesuchamessoutmanyinventionsthatpeopleaboutothers'newinventionsaurdayattack,thisisverycontradictorythings."Heopposestheuseofalternatingcurrentanddirectcurrent,sotheapproveafiercedebateandstubborninfailure.Inthisrespect,reflectstheEdisonbecameacelebrityafterthestubbornnessofstartedtofosterold-fashionedshortcomings.

• this morning i went to the english corner which is in the
park near my home. it is three years since it was founded. many
middle school students as well as college students and foreigners
take part in the activity
. people there practice speaking english by
talking about something interesting. people also exchange the
experience in english learning. i think it is a good chance for me to
use what i have learnt in my english class. i felt very cool after i
got back home. i’ll try my best to learn english better, for it is so
widely used in the world.
