It's wonderful to go to another country, complete a volunteer project and feel that you reallyhave a positive influence. But how can you become an international volunteer?
* Plan practically. Contact the organizationa few months before leaving and find out if thereare materials which are rare and hard to attain forthe project. What you often consider plentifulhere, such as nails or hammers, is in great needin other parts of the world.

If you can't speak thelanguage, smiles work wonders. And you will besurprised — you will find a way to communicate!

Scientists have been puzzled by the phenomenon that migrating ( 迁徙的) birds fly not just ingroups all the time, but in“V”formations andthey have tried to figure out what benefit birds getfrom this particular formation. Now, a researchgroup from University of London may have foundthe answer—migrating birds fly in a“V”to saveenergy, according to a study published in thejournal Nature.
When a bird flaps ( 振翅) its wings, it stirsthe air around it and causes the air to move in different directions. Scientists found in the study thatthe air creates an upward-moving wave at the tipsof the wings, which means that if a bird fliesaround the wingtips of another bird, it can get aboost ( 抬高) from the rising air and therefore useless energy to stay in the air.
But there is a small problem — the lead birdgets no lift advantage and can easily get tired.This is why a group of migrating birds regularlyswitches leaders, according to The New YorkTimes.
Apart from the“free ride”strategy, scientistswere also surprised to observe that migrating birdstimed their wing beats and adjusted their positionsin a very precise way to maximize the lifting effectwhile avoiding areas where the air moved downward.
“They're able to sense what's going on fromthe bird in front, where this ‘good air' is comingfrom and how to position themselves perfectly init, ”lead researcher Steven Portugal told BBC.
In fact, the“V”formation has long beenthought to help birds fly more efficiently ( 效率高地) . A previous study showed that birds' heartrates went down when they were flying together ina“V”formation. Jet fighters were also found tobe able to reduce their energy use by up to 18%by staying near the wingtips of other jet fighters.Both of these findings led scientists to suspect thatthe“V”formation had an efficiency purpose, butuntil now they still lack proof.
“For scientists, the new study provides aninsight into an interesting natural phenomenon.But it could mean even more for aircraft companies — helping them understand how they canimitate that with their plane formations to savefuel, ”said Portugal.
28. What is the author's purpose in writingthis article?
A. To explain how birds benefit from migration.
B. To introduce how migrating birds find their way.
C. To tell some applications of migrating birds'“V”formations.
D. To report new findings about migrating birds'“V”formations.
29. According to the recent study, whenbirds migrate _.
A. they don't often change their lead birdsduring the whole journey
B. they fly in“V ” formations to protectthemselves against enemies
C. they form the shape of a “V ”to makebest use of the lifting effect
D. the air they stir around makes it hard forthe birds behind to fly fast
30. What is the significance of the new studyaccording to this article?
A. It might inspire aircraft companies tothink of ways to save fuel.
B. It has proved that the “V”formation canimprove efficiency in many fields.
C. It has led scientists to discover that birds'heart rates go down when they fly in a “V”.
D. It shows that the best formation of jetfighters in battles should be a “V”formation.
31. The underlined word“imitate”in the lastparagraph most probably means“_”.
A. use
B. copy
C. change
D. learn
D
Facebook ( 脸谱网) friends cannot replacethe real thing, say psychologists ( 心理学家) .
People are happier and laugh 50% morewhen they talk face to face with friends or viawebcam ( web camera) than when they use socialnetworking sites, a study has found.
Dr. Roberts, a famous lecturer at the University of Chester, said such websites don't appearto help people make true friendships. Based ontwo questionnaires ( 调查表) , he found there wasno link between Facebook use and people withlarger groups of friends.
Dr. Roberts, whose work will be presentedat the British Psychological Society conference inHarrogate, said, “The bottom line conclusion isthat our relationships are not dependent on thequantity of our communication. They depend onquality, and even Skype ( 一种网络即时语音沟通工具) is better at increasing the quality of ourcommunication than time spent on Facebook. ”Even talking on the phone or texting does notmake people feel as good as sharing a smile, theresearch says. The studies suggest quality, notquantity, of communication is the most importantfor keeping friends for life.
People find the most satisfying relationshipscome from a small number of close friends, withan outer“ring ” of 10 significant others. Withthese people, it doesn't matter what type of socialmedia you use for communication. But people whowant to “contact the world at large”using Facebook can be disappointed because they spreadthemselves too thinly, claim researchers.
In a third study, Dr. Roberts asked peopleto communicate with friends face to face or viaSkype and keep a 14-day diary. This was compared with communicating via phone, text messages or social networking sites. People communicating face to face or on Skype were 50% more likely to laugh, and they rated themselves as significantly happier.
32. Dr. Roberts's finding that there was noconnection between Facebook use and people withmany friends was _.
A. based on questionnaires
B. based on conversations
C. through instant messages
D. through social media
33. What is the main idea of the fourth paragraph?
A. Most people contact each other online.
B. Keeping a friend for life is not easy.
C. The quality of communication is important.
D. Skype is better at understanding us thanFacebook.
34. What does the underlined sentence inthe fifth paragraph probably suggest?
A. They are too excited to express themselves.
B. They limit their social circle to a smallrange.
C. They spread their information at a lowspeed.
D. They lack information to introduce themselves.
35. What is Dr. Roberts's attitude towardsthe use of Facebook?
A. Positive.
B. Casual.
C. Responsible.
D. Unsupportive.

There are too many cars in our town now.For a result, there are lots of traffic jams, and theair which we will breathe is terrible. Our town isvery old but all the streets are quite narrow, sothere is no room for bus lanes, which mean thatbuses always get stuck in the traffic jams, too.However, lots of accidents with cyclists often happen because of crowded street. But I think thereis a simple solution of these problems. Thegovernment should close city center to all trafficexcept buses and bikes, and build very larger carparks outside the town. Car drivers can take a businto the city center and arrive at work or the shopsrelaxing and in a good mood.

35 . D。考查理解 作者态度的 能力。通过Roberts博士的调查、实 验、研究可知, 朋友圈较大的人们与脸谱网之间没有联系, 想借助脸谱网广泛交友的人们不能把自 己的信息传播得很广, 面对面交流或通过即时语音沟通比通过电话、短信或社交网站交流效果更好。根据这些情况可以推断, Roberts博士对脸谱网的使用持不支持的态度。因此, 该题选D。
第二节
【主旨大意】本文讲述汽车安全带的发明经过及应用。
36. E。考查推理判断的能力。该句以美国使用安全带保护生命的情况与下句世界范围内的情况作对比。因此, 该题选E。
37. G。考查推理判断的能力。根据上文可知, Edward Claghorn发明了一种安全装置, 他称之为“安全带”。因此, 该题选G。
38. F。考查推理判断的能力。该句与上下文紧密衔接, 起承上启下的作用。其他发明家跟着发明了不同版本的安全带, 但是一百多年过去了, 现在通用的安全带才被研发出来, 它是瑞典工程师尼尔斯·布林发明的。因此, 该题选F。
39. C。考查推理判断的能力。该句与上句紧密衔接。尼尔斯·布林发明的三点式安全带包括一条跨越胸部的布带子和一条环绕臀部两侧的布带子, 这种设计将两条带子在挨着臀部的地方连在一起。因此, 该题选C。
40. A。考查推理判断的能力。该句与下文紧密衔接。这位瑞典工程师因为发明三点式安全带而赢得了很多荣誉, 1995年瑞典皇家工程科学院授予他金质奖章。因此, 该题选A。

第四部分写作
第一节短文改错
第1处: For改为As。考查固定短语中的介词。as a result意为“因此”。
第2处: 删除will。考查动词时态。此处讲述现在的一种实际情况, 应该用一般现在时。
第3处: but改为and。考查连词。根据句意“我们的城镇很破旧, 街道相当狭窄”可知, 这两句之间是并列关系。
第4处: mean改为means。考查主谓一致。分析句子结构可知, 非限制性定语从句对前面的句子起补充说明作用。从句中的主语which是关系代词, 替代前面的整个句子, 为单数第三人称形式, 因此谓语动词也应该用第三人称单数形式。
第5处: However改为Besides。考查副词。从上下文语境可知, 此处和上句之间是递进关系而不是转折关系, 即“公交车总是陷入交通堵塞, 此外由骑自行车者引发的事故时常发生”。
第6处: street改为streets。考查名词的数。根据句意和名词的意思可知, 此处的可数名词street应该用复数形式表示泛指。
第7处: of改为to。考查惯用法中的介词。“……的解决 办法”习惯上 表达为“asolution to”。
第8处: city前加the。考查冠词。此处的city center是大家心目中都清楚的地方, 应该用定冠词表示特指。
第9处: 将larger改为large。考查形容词的比较等级。根据上下文语境可知, 此处表示“建造一些大型停车场”, 并没有与上文形成对比, 应该用形容词的原级。
第10处: relaxing改为relaxed。考查非谓语动词。此处表示汽车驾驶员所处的一种“放松的”状态, 应该用过去分词做伴随状语。
第二节书面表达

5.二年级《曹冲称象》说课稿 篇五
《曹冲称象》是统编教材小学语文二年级上册第三单元第四课,这篇课文讲了曹操的儿子曹冲小时候称象的故事,教育我们应该多观察、遇事多动脑筋就能找到解决问题的方法。
二、说学情说目标
二年级的学生通过一年多的语文学习已经具有初步理解词语能力。但曹冲称象这个历史故事远离孩子们的生活实际,需要借助多媒体的图片和动画等帮助理解。根据本课生字很多的特点,选用一个课时的时间,让学生完成识字、写字,让他们对课文有一些初步的了解,第二课时重点在于理解课文,根据学生的实际学习情况,我制订了以下教学目标:
1、认识本课的14个生字,会写10个生字。(教学重点)
2、正确、流利、有感情的朗读课文。
3、理解曹冲称象的过程,懂得只有动脑筋,才能解决生活中问题。(教学难点)
这样设计,是在充分尊重低年级阶段目标的前提下,重视情感、态度、价值观的正确导向功能,从而体现语文教学中的工具性与人文性的统一。
三、说教法和学法
语文课是学生学“语”习“文”,学生应该是课堂的主体,我在遵循低年级学生自身情况特征以及语言阶段性特征,利用多媒体课件激发学生兴趣,在组织课堂教学中利用朗读法,学生自主、合作、探究的方法,掌握教学重点,突破教学难点。在整个教学过程中老师为主导,学生为主体,通过开放而有活力的语文课程,激发学生对语文学习的兴趣,进而全面提高学生的语文素养。
四、说教学过程
1.第一课时,创设情境,导入新课。通过多媒体展示大象图片,引出课题,激发学生学习的兴趣,拉近学生与文本的距离。再初读课文,整体感知,随后课件出示生字词,学生自由认读、指名读、领读、比赛读等不同形式让学生会认会读,对个别易出错的生字词重点指导。然后再读课文,读准字音,读通句子,读好每一自然段,感知课文大意。最后指导书写,按照正确的笔顺书写生字并组词。
2.第二课时复习字词导入,再出示大象图片,让学生围绕图片讨论探究,相机指导朗读课文第二自然段描写大象的句子,进而质疑导入:这么重的大象怎么称呢?这样设计本环节的目的是:利用图片和文中句子的形式吸引学生的注意力,通过质疑激发学生的学习兴趣。通过学生齐读第三自然段,抓住“有的···有的···也有的···”理解官员们不合理的称象方法,就顺理成章的理解了曹操“直”摇头的原因。接着学生同桌合作、探究,利用找找,画画,读读,找到曹冲具体称象的方法,抓住表示顺序的关联词“把···再把···然后···”读懂曹冲称象的方法,然后利用多媒体课件演示曹冲称象的方法,体会这个方法的可行性。
我这样设计本环节的目的是:利用多媒体课件,学生自主、合作、探究,亲自去感受,真正理解课文的内容,在我的引导下,突破本课的难点。
最后把“你还有哪些称象的好方法?”这样一个发散性思维的问题抛给学生,这样设计可以激发学生去大胆构想,培养学生的思维能力,从而达到了升华主题的目的,即遇到问题要多动脑筋。
五、说板书
4.称象
官员们(有的···有的···也有的···)
曹冲(把···再把···然后···)
课文《曹冲称象》说课稿2一、说教材
《曹冲称象》二年级下册的一篇课文,是一篇经典的历史故事。记述了曹冲动脑筋想办法称出大象体重的故事。全文围绕“称象”这一中心,运用渲染烘托、映衬对比的方法记叙了称象的全过程,表现了曹冲的聪明才智,给人以深刻启迪。
二、说学情说目标
二年级的学生通过一年多的语文学习已经具有初步理解词语能力。但曹冲称象这个历史故事远离孩子们生活实际,需要借助多媒体的图片和动画等帮助理解。本课是第二课时,重点在于理解课文。根据低年级学生的说话训练。我制订了以下教学目标。
1、会正确、流利,有感情地朗读课文。
2、会用自己的话说一说曹冲称象的过程。通过官员称象的方法和曹冲称象的办法对比,理解曹冲称象方法的科学巧妙。
3、培养学生爱动脑筋的好习惯。
教学重点:会正确,流利,有感情地朗读课文,会用自己的话说一说曹冲称象的过程。
教学难点:会用自己的话说一说曹冲称象的过程。
三、说内容过程
在讲解这篇课文的时候,我主要分为以下几个步骤。
(一)巧设情境、导入新课
通过创设情境,使学生走进生活实际,了解秤是不能称大象的。所以称大象的难度是可想而知的。
(二)复习生字,朗读课文
学生复习生字词。教师适时指导朗读。使用个别读,齐读的方式。使同学们能够正确、流利、有感情的朗读课文。
(三)辅助动画,理解内容
1、自读课文,初步感受。
2、播放动画,整体感受曹冲如何称象。
3、分步演示,深入理解课文。
4、按照课件的提示,复述称象过程。
5、独立叙述称象过程。
(四)总结全文,拓展积累
通过几个小问题,使同学们懂得做事要想曹冲那样多动脑。
四、说信息技术的应用
下面,我将从以下三个切入点介绍一下信息技术在本课教学的整合。
(一)创设情境,走进历史故事
任何的一个历史故事都产生于特定的时代背景下,本篇文章距离学生的生活实际相对遥远,但是运用多媒体教学技术,就能拉近学生与课文的距离,所以在开课我以大家都很熟悉的秤来导入主题,进而出示大象的图片,大象是否能用秤来称?设置悬念,激发学生思考。利用了多媒体课件色彩鲜明、形象生动、化静为动的特点把学生的注意力吸引过来,同时把教材比较抽象的内容活灵活现的展现在孩子们的面前,直接导入课题,便于学生很多接受知识。
由于学生对于曹冲不是很熟悉,所以我出示一幅关于曹操和曹冲的图片,并且简单给孩子们介绍他们。他们生活在1800年前的三国时期,当时曹冲只有七岁。曹冲是怎样称象的呢?设置悬念,激发学生思考。
(二)多媒体游戏,复习旧知
二年级的识字是一个重点的内容,但是孩子们往往只是机械的记忆,达不到理想效果。我深知兴趣是学生最好的老师。因此,在本课教学中,我利用课件设计了游戏来复习生字,以多媒体游戏为载体,轻松突破教学难点。充分吸引孩子的眼球,提高了孩子兴趣。请看我的教学实录。在进行游戏教学时,同学们情绪高涨、精力集中、积极发言,生怕丢掉一个生字,同学们在妙趣横生的摘苹果游戏中复习了生字,使原本枯燥的识字变得富有生命力。达到了复习生字的学习目的。同时又通过谁能赶走大象的游戏,来进行词语填空,使学生们在轻松愉悦的环境中进行复习旧知。
(三)理解复述,突破难点
二年级的教学仍以朗读作为孩子们的主要任务,这个环节我借助信息教育技术,让孩子们由浅入深的进行朗读学习理解。最初的朗读要给学生一个准确的,直观的印象,所以将课文的重点句呈现在大屏幕上,同时,图片出示大象的身子和腿都像什么,训练孩子们口语表达能力。重点句单独呈现反复连读语气“这么大的象,到底有多重呢?”让同学们把疑问的语气充分读出来。学生自读第二段课文,找到官员们称象的办法。并且理解这些办法行不行,为什么?同时知道学生读出反驳的语气。
二年级的同学具有初步理解词语的能力,但是要让他们对整个故事进行复述就有一定的难度。为了使孩子们能更加直观的了解称象的过程,这个环节我设置了动画来帮助大家理解课文。这样能轻松突破教学难点。首先通过学生自读汇报的方式,让学生对曹冲称象的过程有一个初步、抽象的理解。然后通过看动画片的方式,产生一个完整直观的感受。给学生一个全新的“身临其境”的境界享受,同学们仿佛亲眼看到了,聪明绝顶的曹冲通过动脑筋、想办法称象的过程。
为帮助他们完整的讲出曹冲称象的过程做好铺垫。最后通过再次分步看图提示的方式,让学生用自己的话讲出曹冲称象的过程。这样,把抽象化为具体、乏味化为有声有色的一个过程。这些动画能够唤起学生对语言的主动感悟,积累词语,乐于表达。更有助于学生理解课文内容,掌握学习重点,练习从低年级开始就能有序的说一段话。让学生在一种“现实感”中进行主动地学习。学生通过对课文的理解,培养他们爱学习、爱动脑筋的好习惯。
借助多媒体的教学,丰富了学生的情感体验,提升的学生对语言的感受能力。
