Love in high school is a very sensitive topic, the students in high school have come to the age of being mature, inside, they desire to love someone, but it is the awkward time. First, they need to focus their attention so that they can enter a better college, second, their parents are strongly objective to their love, the teachers even ban the love relationship between students. As a student, they have their own rights to love someone, the inner desire and the objection from parents and schools make them struggle to their emotions. In my opinion, high school students have so many pressure, they should put aside their love emotions for a while, they need to focus on the study, when high school time ends, they can choose their love. It is much easier, if you want to love at the time, then to love. No one will stop you.

爱在高中来说是一个很敏感的话题,高中生已经来到了即将成熟的年龄,他们渴望去爱人,但是这也是一个尴尬的时间。第一,他们需要集中精力学习,以此来考取一个好的大学,第二,他们的父母强烈反对恋爱,老师甚至禁止学生谈恋爱。作为一名学生,他们有自己的权利去爱人,内心的欲望,父母和学校的反对,让他们在情感上做挣扎。在我看来,高中生有很多压力,他们应该暂时把感情放在一边,需要集中精力学习,当高中时光结束以后,他们可以选择去爱。这容易多了,如果你那时想要去爱,就去爱。没有人会阻止你。

When my friends ask me to take pictures of them, they will take a lot of pictures and then only keep a few of them.

Because they are not satisfied with most pictures, they think they are not perfect.

Actually, when I look at the pictures, there is nothing serious in my eyes, everyone in the pictures look as they are.

People chase for the perfect side, that’s why more and more people choose to have the plastic surgery.

Take the celebrities for example, they look beautiful enough, but to make themselves look perfect, most of them take the plastic surgery, which makes them look unnatural. People have to cost the great price for chasing the perfect side, while no one is perfect.

If we accept our imperfect side, we will live in the easy way and can enjoy the life.

当我的朋友们叫我帮拍照的时候,他们会拍很多照片,然而只有少部分照片能保存下来。因为他们不满意大部分的照片,觉得自己看起来不完美。实际上,当我看到照片的时候,在我看来没有什么大问题,照片中的每个人看起来都像他们自己的样子。人们追求完美的一面,这也是为什么越来越多的人选择去进行整容手术。就拿名人来说,他们看起来足够漂亮,但是为了让自己看起来完美,大部分人进行了整容手术,这让他们看起来不自然。为了追求完美,人们不得不付出很大的代价,然而没有人是完美的。如果我们接受自己不完美的方面,那么我们就会过得轻松点,享受好生活。

篇3:如何写好高中英语日记

日记是用来叙述一天中发生的有意义事件的文体。

第一,注意日记的格式:一般是左上角写当天的日期,右上角写当天的天气情况(cloudy/clear/windy/rainy/fine/snowy…)。日期通常采用两种写法:一种是按“月、日、年”顺序;另一种是按“日、月、年”的顺序。注意要在年份之前有一个逗号,而且月份通常可用缩写词(如:Jan.,Feb.,Mar.等)。如果需要写星期,可将其写在日期的前面或后面。如:Monday,May15th,2008或May15th,2008,Monday

第二,抓准日记的时态:日记记叙的时间通常是在当天的下午或晚上,因此所用的时态多为过去时态。但应灵活掌握,如果日记叙述天气、描写景色或为了描写生动,也可用现在时。

第三,日记一般按事情发生的先后顺序记述,所以常需借助一些表示先后顺序的词语,如atfirst,then,lateron,afterwards,finally,atlast等。一定要注意句与句、段与段之间的连接和过渡,适当使用一些过渡词语使其连接紧凑、过渡自然。

第四,确立日记的中心要点,尽量突出主题,可以通过对某个细节、某个侧面的描写来突出主题,千万不要写成一个流水帐。

一、形成性评价的概念

形成性评价(Formative Assessment)是美国评价学专家斯克里芬在1967年在其所著的《评论方法论》里提出来的。所谓的形成性评价是相对于传统的终结性评价(Summative Assessment)而言的,指的是对学生日常学习过程中的表现、所取得的成绩及所反映出来的情感、态度和策略方面的发展做出的评价,这种评价是通过对学生学习的整个过程持续观察、记录和反思之后得出来的。

形成性评价的目的是为了激励学生学习,帮助学生调控自己的学习过程。让学生获得成就感,增强其自信心和团结合作精神,让学生从被动接受评价变成一个评价的主体和积极参与者。形成性评价能够帮助教师了解学生的学习情况,从而制定下一步的教学计划。与终结性评价相比,形成性评价不只以考试成绩来衡量学生的学习情况,它更加灵活方便,也更加科学有效。形成性评价注重对学生学习行为和表现的评估,能够有效发挥学生的主动性和创造性,有利于培养学生的学习兴趣,也能够有效提高学生的自信心。

英语口语教学中运用形成性评价,能够让学生在课堂中互相评价,增强学生参与课堂教学的积极性,在提高英语口语能力的同时体会到成功的快乐,形成一个教师与学生、学生与学生之间良好互动的课堂。形成性评价注重开发学生的创新能力和思考能力,而要培养这些能力就必须依靠坚持不懈的学习和运用来完成。

二、形成性评价的方法与工具

首先,一般而言,形成性评价的方法大致分为:自我评价、同伴互评和教师评价。

自我评价是指学生在学习的过程中就自己学习进程中的某个阶段性成果的总结和评价。自我评价是形成性评价中尤为重要的评价方法,只有通过自我评价才能尽力发挥其的主观能动性,积极主动地参与课堂教学活动。只有主观积极地参与课堂,就自己不同阶段的水平,才能更好地定位自己进一步的目标,并在课程初期、中期及末期分别给予自己相对客观中肯的评价,以促进下一阶段的学习。

同伴互评是指在课堂活动中,就某一活动进行同学之间的评价,评价包括学习态度、学习能力及学习方法的评价。在同伴互评的过程中,学生们可以相互探讨学习方法、交流学习心得、提出改进的建议和意见。同伴之间相互比较、竞争,相互取长补短,既增强了合作精神又促进了学习能力和学习效率的提升。同伴互评作为形成性评价重要的方法之一,其评价形式既增强了课堂的趣味性又增强了学生的学习自信心和学习热情。

课堂学习的主体是学生,但是学习评价的主体却是教师。形成性评价侧重过程教育,在教学过程中,根据需要调整教学计划和内容,该评价尤其重视学生与教师在课堂的共同参与度,而非教师“一言堂”。首先,教师在教学过程中设定好学生自我评价与同伴评价的量化标准,列好学生自我评价和同伴评价的核查表;其次,学生根据核查表才可有的放矢,对照核查表所列的内容一一检查,每节课后,客观公正地给予自己和他人中肯的评价;最后,结合学生自我评价和同伴评价的反馈结果,教师针对学生课堂上的表现,纵向对比某一特定学生评价前后的差异,或者横向比较某一特定组别在同一活动中每位学生各项指标的完成情况,同时,以多种形式反馈给学生并提出整改意见。因而,在教学的不同阶段,根据学生的能力发展状况,教师可适时调整评价方式,不断改进教学方法和教学手段。

只有将自我评价、同伴评价与教师评价结合在一起评价方式才能保证较好的教学效果,才能促进教育改革的进一步深化,真正达到以素质教育培养复合型人才的终极目标。

其次,形成性评价的行为评估工具有课堂观察、学生档案、座谈、问卷调查、访谈和对话周记等。如何运用以及怎样运用这些评价工具要根据所授课程、课程目标和授课对象等诸多因素做适当调整。

课堂观察是教学行为和技巧的基本方式。根据Genesee and Upshur(2001:79)的观点,教师在观察的基础上,可以评估学生已掌握和未掌握的内容。换言之,教师应该评估促进或阻碍学生学习的策略。与此同时,教师还可评估一些特定的教学策略的有效性,确定学生们欣赏哪些课堂活动和形式。课堂观察有助于教师更好地了解课程设计和学生需求的契合度。通过正式或非正式的观察,教师可掌握大多数学生对于教学安排的可接受程度,根据学生的需求改进或调整教学安排等,以提升教学效果。

“questionnaires and interviews can all be thought of as conversations between students and teachers”(Genesee and Upshur,2001:136)。如上所述,问卷调查和访谈都可被看作教师和学生间的对话,访谈和问卷调查是相似的,但决定使用访谈或者问卷调查可依据不同的教学目的。无论是哪种方式,都是老师和学生之间相对正式的会谈,这非常有利于老师对他的教学效果进行评估,诊断学生在英语学习遇到的困难,为学生寻找合适的解决问题,获得良好的学习策略和学习得到更多的进步。访谈和问卷调查设计应该根据学生的个人需求并符合教学目标。

对话周记作为教师和学生沟通的另一种方式,深受学生的喜爱。因课程设置和班级规模的不同,课堂观察、问卷调查及访谈都相对比较片面,而对话周记则可以关注到每个学生的不同需求。师生间定期通信,既增加了教师和学生之间的相互了解,增强彼此的信任,又能解决学生的个案问题,做到因材施教;同时,为了促进“教学相长”,学生可及时反馈教师的课堂教学,对于教师的教学提出较好的建议和意见。

学生档案是一个综合各项评估功能于一体的评估工具。它可以记录学生的成长、课堂变化且兼顾多种需要。如今,众多评价工具只把学生作为评价的对象,而评估的责任和任务的则落到了教师身上。但事实上,几乎没有一种评价工具能很好地管理学生活动并对其课堂行为负责。相比之下, 建立学生档案,需要学生亲力亲为;本着自我负责的原则,他们要更好地自我监督和控制,同时,在建档案的过程中,学生可以见证自己的进步与成长,增强学习的自信,提高学习的效果。

三、形成性评价对于英语口语教学的重要性与紧迫性

众所周知,教育评估在大学英语课程改革中扮演着相当重要的角色。英语教学的重点已从传播知识转移到培养能力。多年来,在中国,人们只注重英语写作和阅读的能力的提升,而一直忽视英语口语交际能力。多年来,教学评价已经被狭义理解为量化教学,而后进一步局限于教学测试。考试作为教学的终极目的,期末考试的成绩也就成为教师评价学生的最重要的依据。而对于口语课堂,单一的这种评估方式和依据增加了大多数学生的心理压力和少部分学生侥幸心理。考试成绩给学生很大压力,危害学生的发展,评估过程中,学生一直被动地参与,无法调动其积极性。当课程结束时,教师将得不到及时准确的学生反馈,无法改善评估方法以助于提高学生的英语口语能力。

“形成性评价源于诊断性测试。与终结性评价相比,形成性评价通过教学过程中多方面的评价发现问题,解决问题,强调过程性、目标性和学生学习的主动性。” (魏薇,2005) 鉴于终结性评价在口语测试评分中的片面性和主观性,大学英语口语表达能力的培养还是受到了这种终结性评价的制约。在大学英语口语教学中,形成性评价最重要的任务的是帮助教师监控学生英语口语的学习过程,提高学生的英语口语学习。如能将形成性评价的理论引入大学英语口语课堂教学与测试中,建立大学英语口语课程与形成性评价相结合的评估模式,则会推动大学英语口语教学和测试的改革进程。

鉴于口语课堂的特点,为了克服传统终结性评价对于口语课堂的制约性,形成性评价与大学英语口语教学相结合有其不可忽视的重要性和紧迫性。

首先,由于口语表达能力除了包含最基本的发音、词汇、语法能力还有语用能力、文化知识储备力等多项复杂的技能,而所有的这些技能无法在某一次测试中完全体现出来。因口语学习的最终目的是运用到相关学科、为了更好地促进国际交流。

而形成性评价尤其注重过程教学,这种评价将教学过程分成了诸多阶段,学生可在每个不同的阶段就自己的学习态度、发音、语言运用的准确性、流利程度以及课堂活动参与的积极性进行横向的同学互评和纵向的自我比较。一方面,横向比较可以找到彼此间的差距,互相帮助已达到各方面的提升;另一方面,学生可在整理学习档案的过程中,纵向比较自己前后阶段的学习情况,时刻了解自己在每个阶段的学习状况,在教师和同学的辅助下,运用不同的学习方法和策略,逐项提高自己的口语能力。 另外,教师在学生进行评价的过程中,可真实地参与并记录学生在各方面的真实水平。

其次,口语课堂实际上是教师与学生、学生与学生之间的互动交际。教师需要花费大量的时间设计口语活动、鼓励学生参与活动、监控课堂活动、诊断学生的需求和问题、记录学生的表现等。学生则在各种学习任务和活动中不断地练习、发现问题、纠正偏差。

与传统的终结性评价不同,形成性评价的最显著特征是评价的主体是学生,学生和教师共同参与课堂,缺一不可。根据多数学生的关注点,学生参与确定研究目标、评分标准和英语口语的性能评估。因而,他们了解每一项活动的任务和目标,他们可合理运用各种评价方式和工具,课前认真准备,课堂上积极参与,能与教师积极互动,课堂上客观地评价自己、同伴和教师。这不仅是一种评价过程,更是学生回归自我认同感的方式。学生增加了学习自信,在评价过程中不断积累经验,逐步获得学习成就感。教师亦可在与学生互动的过程中,更好地了解学生的知识掌握和课堂反馈情况,根据反馈适时调整教学方法。如此良性循环,既增强了课堂的趣味性又提高了学生的学习效率。

四、结语

形成性评价,作为正常教学和学习过程的有机部分,可以全面、客观、科学、准确地提供与其学习目标相关的重要信息,它有助于促进学生的个性化发展和外语教学质量的根本性提高。形成性评价其中的一个重要作用是培养学生良好的英语学习习惯。将英语形成性评价与口语教学紧密地结合在一起,能提高学生学习的兴趣并及时、准确、客观地反映学生的真实水平,使学生的英语口语能力稳步提高。通过采用具体的形成性评价方式,发展学生的自我评价与学生间相互评价的能力,以促进学生的自我反思与自我管理能力。从而提高学生自主学习意识与自主学习能力,并为他们养成终身学习的意识与习惯打下基础。

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

I have a dream today.

I have a dream that one day every vally shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.

Wow, what a dream it has been for Martin Luther King. But the changing world seems telling me that people gradually get their dreams lost somehow in the process of growing up, and sometimes I personally find myself saying goodbye unconsciously to those distant childhood dreams.

However, we meed dreams. They nourish our spirit; they represent possibility even when we are dragged down by reality. They keep us going. Most successful people are dreamers as well as ordinary people who are not afraid to think big and dare to be great. When we were little kids, we all dreamed of doing something big and splashy, something significant. Now what we need to do is to maintain them, refresh them and turn them into reality. However, the toughest part is that we often have no ideas how to translate these dreams into actions. Well, just start with concrete objectives and stick to it. Don’t let the nameless fear confuse the eye and confound our strong belief of future. Through our talents, through our wits, through our endurance and through our creativity, we will make it.

Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up and make it alive from today.

高中英语日记(三)

The hot sun is like our enthusiasm, because no matter how hot the weather is, we still keep on studying English hard.

Today, the chinese teacher taught us some English songs. I like the song which is called ”seasons in the sun” very much. We all lost ourselves in the beautiful voice. Today our theme is youth. After the teacher spoke. I suddenly understand that maybe being young is our advantage, so we must value every minute. We have to do something significant.

In the afternoon, our American teacher is father who is an associate proferssor of English from central college give us a lesson. He told us something about higher education in the USA. I think it will be useful for our future.

On the other side. I felt uncomfortable today. Perhaps it’s a small regret for such a wonderful day. But I think tomorrow still will be rosy.

As the saying goes, "the state-owned national law, the home has rules", "no rules, no fangyuan." We have this home some unwritten rules.

Smokers. The house rules is mainly for my father. Want to know, my father had always loved smoking and smoking will open the floodgates, one, like the fire, a pack of cigarettes a blink, often by his home of cigar smoke. My mother and I often tried to persuade him to smoke less, smoking does no good to the body. But my dad always said: "no big deal, big deal I quit!" But he still as before. Mother see in the eye, pain in the heart, decided to "save" my father to help him "right."

One night, we just had a meal soon, dad is smoking a cigarette, spread "magnificent smoke at home. Mom saw very unhappy, angry look dad, dad but he said cheekily, "just a, a!" But, before long, his smoking again, and one, more. The rob people smoke permeated the room, I just and mother kept coughing. I cant help but say: "father, beginning from today, you can no longer smoke. If smoke again, I would to you a" dictatorship of the proletariat "!" Dad a listen to immediately protest, said: "I object!" "Do you know the dangers of smoking have how old?..." Ill persuade "that - well, I quit!" Dad also aware of the error, also accepted the "commands".

Since the house rules promulgated, dad smoking have trouble, we are proud of my father.

俗话说,“国有国法,家有家规”“没有规矩,不成方圆。”我们家就有这样一些不成文的家规。

抽烟者罚。这条家规主要是针对我爸爸定的。要知道,爸爸平时最爱抽烟,而且一抽就一发不可收拾,一支接一支的,像烧火一样,一包烟眨眼工夫就没有了,家里常常被他弄得乌烟瘴气的。我和妈妈经常劝他少抽一些,烟抽多了对身体没有好处。可是爸爸总是说:“没什么大事,大不了我戒烟嘛!”可他还是一如从前一样抽。妈妈看在眼里,痛在心里,决定“挽救”爸爸,帮助他“改邪归正。”

一天晚上,我们刚吃完饭过不久,爸爸就叼着一支烟,在家里散播“迷魂烟雾弹”。妈妈见了很不高兴,生气的看着爸爸,爸爸却嬉皮笑脸地说:“就一支,一支!”可是,没过多久,他又抽起来了,而且一支接一支,变本加厉。屋子里到处弥漫着抢人的浓烟,熏得我和妈妈不停地咳嗽。我忍不住说:“爸爸,从今天开始,你再也不能抽烟了。如果再抽,我就对你实行”无产阶级专政“!”爸爸一听立即提出抗议,说:“我反对!”“那你知道抽烟的危害有多大吗?……”我就以理服人“那——好吧,我戒!”爸爸也意识到了错误,也接受了“命令”。

自从家规颁布以后,爸爸抽烟的毛病收敛多了,我们为爸爸感到骄傲。

Thanksgiving Day

Thanksgiving is a holiday celebrated in much of North America, generally observed as an expression of gratitude, usually to God. The most common view of its origin is that it was to give thanks to God for the bounty of the autumn harvest. In the United States, the holiday is celebrated on the fourth Thursday in November. In Canada, where the harvest generally ends earlier in the year, the holiday is celebrated on the second Monday in October, which is observed as Columbus Day or protested as Indigenous Peoples Day in the United States.

Thanksgiving is traditionally celebrated with a feast shared among friends and family. In the United States, it is an important family holiday, and people often travel across the country to be with family members for the holiday. The Thanksgiving holiday is generally a "four-day" weekend in the United States, in which Americans are given the relevant Thursday and Friday off. Thanksgiving is almost entirely celebrated at home, unlike the Fourth of July or Christmas, which are associated with a variety of shared public experiences.
