垃圾分类从我做起作文1000字

垃圾分类到我家作文字 学校的垃圾分类宣传己深入我的内心,我自告奋勇的做起了我们家的环保小天使。绝不纸上谈兵,在我的倡议下,家里准备了四个垃圾筒,分别装四类垃圾。爸爸妈妈也在我的带动下,习惯了四个垃圾袋子并存的现实。 可是有一天,我却被打击了。打击我的不是难度极高的什么归入可回收垃圾,什么归入厨余垃圾,什么归入有害垃圾,什么归入其他垃圾。我提着四个装满分好类的垃圾袋子下楼,在楼下刚好看到了收垃圾的清洁工叔叔。叔叔热心的接过我手里的垃圾,将它们一股脑扔在垃圾车上。这怎么会保证这四个袋子会始终分类? 可以用土壤埋起来,成为有机化肥也可以利用腐化产生的能量做清洁能源;有毒垃圾会污染环境,我们就收集起来做特别处理;余下的其他垃圾就会减少,其他垃圾的焚烧少排出有害气体,填埋少占用空地。 叔叔再来的时候,车子被区分成了四部分。不只是这个叔叔,其他清洁工叔叔阿姨也改造了垃圾车。我想如果每个人都进行垃圾分类,地球妈妈就不会再资源短缺,不再臭气漫天,我们人类将迎来美好的未来! 垃圾分类从我做起作文字 随着经济的发展,科技越来越发达,但是人们忽略了垃圾分类的重要性,他们随地乱扔垃圾,严重污染了环境。 暑假的一天,我和小伙伴们一起去公园玩,回家的路上我买了瓶可乐,可当我喝完准备把可乐瓶扔掉时,发现垃圾箱已经“换上新衣服”:原本土黄色的垃圾箱穿上了蓝色和黑色的衣服。“可回收垃圾…… 嗯,其它垃圾。”我歪着脑袋念道,“那我应该扔进哪个呢?”我呆呆地站在垃圾箱前,看着手中的瓶子,有些不知所措。于是我决定去 问问路人。一个阿姨迎面走来,我连忙问:“阿姨,请问一下可乐瓶应该属于哪类垃圾?” 阿姨地笑着说:“不好意思,小朋友,我也不知道啊!”说完,她就匆匆地走了,我又去问一个大哥哥,他很不耐烦地回答道:“随便扔,反正有人会处理的!”我想:如果这样的话,那为什么还要分这么多垃圾箱呢?正当我郁闷的时候,一个身穿制服、手拿扫帚的环卫阿姨拍拍我的肩膀,然后说:“可回收垃圾包括各种瓶子、报纸、纸箱等;其它垃圾包括卫生纸、

高考英语短文改错常见错误类型

短文改错常见错误类型: 1.动词的错误是历年考试的重点和热点,常见动词错误类型有 ①一般现在时与一般过去时错用 ② and前后动词时态不一致 ③主谓不一致 ④缺少动词,特别是be动词 ⑤第三人称单数形式错用; ⑥主动语态和被动语态错用。 如2014新课标全国卷I Since then—for all these year—we had been allowing tomatoes to self seed where they please. 答案:had改为have 本句的时间状语是all these years,通常和现在完成进行时连用。所以使用have been doing的形式。 如2014新课标全国卷II My dream school starts at 8:30 am and ends at 3:30 pm. There are three lesson in the morning and two in the afternoon. We didn’t need to do so many homework. 答案:didn’t改为don’t 本文叙述“我”的梦想学校的情况。根据文章第一句My dream school starts at 8:30 am可知本文基本时态是一般现在时。 如2014新课标全国卷II We can lie on the grass for a rest, or sat by the lake listening music. 答案:sat改为sit 本句中的or表示选择关系,也是一个并列连词,所以与前面的lie同样都使用动词原形。 如2014四川卷 Today, I am going to talk about what you should do when a fire alarm go off. 答案: go改为goes。本句的主语a fire alarm为单数,谓语动词使用第三人称单数形式goes。

初中作文:关于垃圾分类的作文3篇

关于垃圾分类的作文3篇 导语:垃圾分类,指按一定规定或标准将垃圾分类储存、分类投放和分类搬运,从而转变成公共资源的一系列活动的总称。分类的目的是提高垃圾的资源价值和经济价值,力争物尽其用。下面是小编分享给大家的写垃圾分类的作文,希望对大家有帮助。 篇一:关于垃圾分类的作文垃圾,是我们日常生活中常见的东西,它们有的是旧布料和废纸巾,有的是塑料瓶和废电池,有的是果皮杂物。它们给世界带来了污染,因此,我们要将他分类,将一些垃圾回收再利用。 有一次,我在家看了一条公益广告,上面是关于垃圾分类的,它让我有很大的感想: 废纸回收,废纸主要包括报纸、期刊、图书、各种包装纸、办公用纸、广告纸等。那有的人会问了,为什么纸巾和厕纸不能回收呢?哈,是因为它们的溶水性太强了,不能回收。现在知道至今是不能作为回收的,所以一定要节省至今哦。 之后,废纸就会被运往再生厂,将它们做成纸浆,再次造纸,然后再回收,再造纸,就这样的循环过来。所以,这种方法不仅节约了纸张,还能少砍些树木,保护环境。 有害垃圾,主要有废电池、废日光灯管、废水银温度计、过期药品等。这些垃圾须丢进有害垃圾桶中,再由专

业人员进行处理。在这里我要提个醒,碰过有害垃圾的人,那手上就会有残留的细菌,要洗洗手才能吃东西。 厨余垃圾,包括剩菜剩饭、骨头、菜根菜叶、瓜果皮……它们经过生物技术处理,变成了肥料,然后培养植物。就这样,既不会污染环境,还能净化空气呢。 砖瓦陶瓷、渣土、厕纸、纸巾等,这种难以回收的有害垃圾,它们是经过填埋减少污染。 看完了这段广告,我不经赞叹起来,原来我们不知道的实在是太多了。 垃圾分类,从我做起!希望我们能通过垃圾分类,让世界更美好。 篇二:关于垃圾分类的作文随着环保意识的不断强化,我们学校的脚步也不落人后,所以我的工作量瞬间爆增,每当第二节课时,我便会如坐针毡似的,而快接近下课时,心中更是忐忑不安,垃圾分类大挑战让我紧张万分,只因为,我又得跟“垃圾们”来场近身肉搏战了。 “哔……砰!砰!哔……砰!砰!”我像个小小指挥家,指挥着堆积如山的垃圾,“杯子套起来!那边的塑胶袋!进去!铝罐也是!杯子套好!计算纸,滚回你的家!”随着时间一分一秒过去,我也整理好了,接着,我便火速的冲下楼,转个弯,三步并做两步的跑走,好不容易,才抵达初一年级一回收场。

高考英语专题短文改错二十篇1-20(附答案)

1. Three friends and I was driving on a highway. While we were going at least 50 miles per hour, we passed over a car. It had broken down, stopped on the side of the road. My friend slows down, and pulled behind the other car. He got out of the car immediate and before I knew it he was helping the other person push the car down the road to a spot where wasn’t so close to the passing cars. From the way they were pushing the car, it looked as if my friend was pushing them all by himself. I thought my friend help a complete stranger like this was a great thing, but I won’t forget his good nature or character. 2. Dear Brad, I’m very glad to hear from you. In your last letter you ask about the post-80s in China. Actually I am the boy who belongs to this group. Comparing with our parents, life for us is getting much hard. The job market is tough and the house is expensively to afford. Now many girls prefer to marry with a man who owns a house and a car. Therefore, I don’t think love built on house and cars is true love, and I doubt how long it will last. As a matter of fact, though situations are tough today, a lot of we post-80s are making great efforts live a good life. I believe we will have a nice future. Li Hua 3. Good morning, ladies and gentlemen, Some of us are having problems about our parents, as they often look into our school bags or read our diaries. I fully understand why we are comfortable about it, but it is no need to feel too sadly. Our parents are checking in our bags or diaries to make sure we’re not getting into troubles. They have probably heard of some horrible stories about other kids and thinking we might do the same. Or perhaps they just want to connect with us and are doing it all wrong. My suggestion is: Tell them we want them to trust us as many as we’d like to trust them. If you don’t think you can talk to them, write them a letter and leave it lie around --- they are bound to read it. Thank you!

高考英语短文改错分类解析

高考英语短文改错分类解析 解题步骤: 1. 着手篇章,了解大意 考生做短文改错时,不应急于改错,而应先把文章浏览一遍,弄清文章的脉络层次和中心思想,把握作者所采用的时态、语态、人称和数。可以先把短文中明显的错误(如固定词组、词性、单复数)或认为有可能的错误(如句子结构的错误)用铅笔轻轻地标出来,为下一步正式改错做准备。 2. 逐句分析,依句改错 在短文改错中,题随行出、错随句生。因此,考生应在略读全文、把握文章中心思想的基础上,对文章进行逐行逐句研究,从词汇的用法、句子的结构到文章的篇章逻辑都要进行仔细地推敲,把错误之处一一改正过来,切不可孤立地依行改错。若一时发现不了错误,不要揪住一处不放而耽搁太多时间。可以在全文改完以后,再回过头来进行难点突破。若已改出了八、九处错误,剩余一两处实在找不出错误而时间又来不及时,则大胆地打上钩,不留空白。当然,有些考生在考试过程中由于紧张而脾气急躁,一看找不到错处就打勾,这也是不明智的。因为近几年来,该题的出题方式基本稳定,只有一处是正确的。 3. 复读全文,检查核对 考生在做完短文改错题后,务必要把已改好的短文复读一遍,查看是否出现疏漏或遗漏的地方,特别要注意时态、语态、代词所指及人称和数等篇章逻辑方面的问题,检查无误后方可定稿作答。 错误分类解析: 高考英语短文改错分类解析---名词 一、考点规律分析 短文改错的名词考点主要涉及名词的单复数问题,即在该用复数的地方误用其单数,或在该用单数的地方误用其复数。 二、真题单句归纳 (1) We stopped to rest for a while and to drink some waters from a stream. (2) We climb everywhere, not only in America. We have been to Europe many time. (3) There are branch library in many villages. (4) I hope that you two could come and visit us some times soon.

垃圾分类保护环境作文6篇

垃圾分类保护环境作文6篇 ----WORD文档,下载后可编辑修改---- 下面是小编收集整理的范本,欢迎您借鉴参考阅读和下载,侵删。您的努力学习是为了更美好的未来! 垃圾分类一 今天是星期一,下午2点钟30分,我们进行了社会实践活动(公益)----捡垃圾。 我们每个班分成两组,一队在路南,一队在路北。我和几个好朋友分在了路北。 我们正好捡了40分钟的垃圾,才捡了40分钟的垃圾就已经气喘吁吁了,那清洁卫生的叔叔阿姨们每天起早贪黑的打扫见到,那得有多累啊! 我们每两个人拿一个袋子,带上环保手套,一路上捡了不少垃圾,这说明人们有多么不爱护环境啊!我在检垃圾的时候听到几位老爷爷说上次市里来的官员来查的时候,某某某(居住城市名)是环境最差的城市。由此可见,我们更应该好好保护环境,不能落在别人后面。 我们捡了许多垃圾,但还是不怎么干净,一定是在我们剪完后又有人乱扔了。这是在外面,如果是在自己家里呢?他(她)们一定不会乱扔。 有些人嘴上说“保护环境,人人有责”,可是到了实际的时候,又有几个人会像自己说的那样做呢?因此,我们的环境总是很差。 有些人,对大街上的标语和垃圾箱视而不见,将垃圾直接扔到地上。不管在什么地方,只要有垃圾就随地乱扔,明明在不远处就有垃圾箱,难道他们忘记了自己每天说的“文明只差一步”了吗? 有一句名言“但存方寸地,留与子孙耕”,他们现在不好好保护环境,那以后他们的子子孙孙又要怎么生存呢?所以,我们要好好保护地球,保护环境,造福与我们的子孙后代。 这次通过捡垃圾的活动,我懂得了在课本上学不到的道理,我以后要多参加这样的活动,懂得更多道理,让自己的只是变得更加丰富! 垃圾分类二 我们老师组织我们同学去温州乐园春游。大家自然非常高兴。

英语短文改错常见类型

英语短文改错常见类型 1. while 和when ●when 解析〔引导时间状语从句〕 (1).表明一个动作发生的时候,另一个动作正在进行之中。例如: When the teacher came into the classroom ,we wereplaying.当老师走进教室时,我们正在玩闹。 (2).表明当某一动作正在进行时,另一动作发生了。如: When Lily was flying a kite,she found a child crying on the ground.莉莉正在放风筝时,她发现操场上有个小孩哭。 〔特别提示〕当when从句放在主句之后时,它更强调某一动作的突然性,此时的when相当于and then,and suddenly,just at that time。 I was taking a walk when I came across Lily.我正在散步时,(没想到)遇见了莉莉。 特别是主句中有just,或when从句中有suddenly时,这种突然性更为明显、强烈。例如:We were doing my homework at home last night when the lights went out.昨天晚上我正在家写作业时,灯(突然)灭了。 〔相关链接〕when引导的状语从句除了上述意义之外,也常具有其他一些含义:1.一……就……(=as soon as) We will stand up when the teacher comesin.老师一进来我们就起立。 2.虽然;然而;可是(=although) We had only five boxes when we needed eight.我们需要八个箱子,可是只有五个。 3.每当……(=whenever) It is always very hot here when it is summer.每当夏季,这儿总是很热。 4.既然(=since,as) Why did you come here on foot when you know you should come by bike?既然你知道该骑自行车来,你为何还要步行呢? ●while 解析 while引导状语从句,有以下两种含义: (1).表示某个动作正在进行的同时,另一动作也在进行之中,这时主从句都用进行时态,有对同类的两个动作进行对比的意味。如: While I was playing the game,she was readcing.我在玩游戏,她在读书。 (2).表示某个动作正在进行时,又发生了另一动作(该动作用一般过去时)。如: While I was reading,I fell asleep.我读着读着就睡着了。 〔相关链接〕 while还有以下几种常见用法: (1).只要(=as long as) There will be life while there is water and air.只要有空气和水,就会有生命。 (2).而;然而〔表示对比〕 He is a driver while I'm a teacher.他是司机,而我是老师。 (3).虽然(=although);尽管〔表示让步〕 While I see what you say,I can't agree with you.虽然我能理解你说的话,但是我不能同意你。(4).用作名词,表示“一会儿或一段时间”,常与a,the或this等连用。如: Just wait a while and then I will help you.等一下,我会来帮你的。 2.不定冠词与定冠词

高中生垃圾分类作文800字【三篇】

高中生垃圾分类作文800字【三篇】 记得前几年在德国旅游的时候,我在超市里看到一台陌生的机器,它有点像自动取款机,但面板上一个又大又圆又深的孔洞宣告了它另有用途。正巧此时有人来使用,我便好奇地在一边观察。这人拎着个布袋子,里面装了大大小小十几只空塑料瓶。只见他把塑料瓶条形码朝上依次从圆孔放入,瓶子经过扫描后就“扑通、扑通”地被吞了进去。全部放完之后,旁边的屏幕显示出塑料瓶的总数和一个金额,他按下确认键,机器随即“唰”一下吐出一张卡片,他放进口袋就离开了。这机器挺受欢迎,我饶有兴趣地连着看了好几个人进行相同的操作。同时我发现:人们投进机器的塑料瓶都是干干净净的,并没有残余的饮料和水。 当地的朋友看我很感兴趣,热情地向我介绍说:这是塑料瓶回收机,每个超市都有这个机器。因为德国每一瓶水的售价都包含了至少0。25欧元的空瓶押金,远远高于饮料本身,所以德国人习惯了把空塑料瓶洗干净后带到超市投入回收机器,凭打印的小票可以在结账时抵扣货款,或者直接换成现金。也有人会把空瓶送到专门的地方,让无家可归者拿去换钱。 “无论是谁拿走,最终都会送进回收机器。你知道吗,德国的塑料瓶回收率达到97%呢!” 听着他的介绍,语气中有隐隐的自豪,我心里又惊讶又佩服。心

里不由得生出强烈的期盼――什么时候在我生活的上海也有这样的回收机器呢? 我们对喝瓶装水和瓶装饮料早已习以为常,喝完顺手扔进垃圾桶,渴了再买一瓶,多方便啊!但是,能主动把塑料瓶投进垃圾桶还算好的,有很多塑料瓶被人们图方便随手丢弃在马路边,草坪中,甚至河道里,虽然不情愿但又不得不承认,我们对此似乎也习以为常了…… 上海是个现代化国际大都市,在很多方面都毫不逊色于发达国家;但在垃圾分类回收这件事上,我们的观念和行动都落后了。好的观念要有好的措施来配合,才能相得益彰,发挥更大作用。 “这个洗发水瓶子是什么垃圾啊?是干垃圾还是可回收垃圾?还有这个……”所幸的是,如今上海正进行生活垃圾强制分类,相信在不久的将来,塑料瓶回收机和更多更强大的设备也能在上海看到,而这些机器设备的使用也会帮助我们把垃圾分类的工作做得更好。 我坚信,垃圾分类很快也成为我们的习惯,而那将标注我们这座城市文明的新高度。【篇二】 这一种情景在我们生活中也许是司空见惯的。同样司空见惯的还有垃圾分类。 垃圾分类,这已经提出好几年了,也倡导市民垃圾分类好几年了。为什么要垃圾分类呢?垃圾分类,是将垃圾按可回收再使用和不可回收再使用的分类法为垃圾分类。人类每日会产生大量的垃圾,大量的垃圾未经分类回收再使用并任意弃置会造成环境污染。垃圾分类的优点又是什么呢?1、减少占地:生活垃圾中有些物质不易降解,使土地

The last thing was to go on helicopter ride. My little sister was so young to go by herself, so I volunteered to accompany with her on the ride. When I got into the helicopter, I attempt to close the door. Airplanes have doors;so do a helicopter. Wrong!The pilot told me that there was no door as they went skywards. I had never been more frightening in my life. It’s a good thing which the ride lasted for only 15 minutes. No more air rides for me, I swear! 解析: ①before常与完成时连用,ago常与一般过去时连用。句意:几年前,我们全家去佛罗里达参加了一次海鲜节。 ②海鲜好吃,天气很好,坐船的经历也很棒。三个分句之间为并列关系,而不是转折关系,故改but为and。 ③句意:最后一件事就是乘坐直升机。ride在句中意为“乘坐;搭乘”,为可数名词,此处表示泛指,故加冠词a。 ④句意:我妹妹太小,不能独自前往,因此我主动提出陪她乘坐。too...to...意为“太……以至于不能”。 ⑤accompany“陪伴”为及物动词,故直接跟宾语,不用介词。 ⑥由When引导的时间状语从句中的谓语动词的时态(一般过去时),可推知主句谓语动词需用一般过去时,故将attempt改为attempted。 ⑦句意:飞机有门。直升机也有门。根据前一分句中的have可知本句用一般现在时态,主语a helicopter为第三人称单数,故将do改为does。 ⑧“我”和妹妹都在直升机上,所以用代词we作主语。 ⑨frightening意为“吓人的;令人害怕的”;frightened意为“感到害怕的”。错误处表示“感到害怕的”, 故用形容词frightened作表语。 ⑩本句中It为形式主语,主语从句为真正的主语,由that引导主语从句。Correction 2(2018重庆七校第三次诊断) The other day, as I walked to school, I passed small construction area. It was not far away in my school. I notice a man bringing a bunch of things: shoes, blankets, some canned food, and clothing.Perhaps the items were gathered from his family and some of his friend. He started laying it down for people to take. Certainly, I was curious about what things would be going. But I rushed there after school. I saw that much of the items were taken by others. I have read lots of inspired stories of kindness. This is probably the sweetest act of kindness I’ve been witnessed so far. 解析: ①句意:几天前,我走路去学校的时候,途经一处小建筑工地。根据句意可知此处表示泛指,area(区域,领域)为可数名词,故small construction area前加a。 ②far away from...为固定短语,意为“距离……远”,故将in改为from。 ③根据首句中的时间状语The other day并结合语境可知,此处叙述过去的动作,故
