A

If you travel to a new exhibit at the San Francisco Conservatory of Flowers, you will have chances to see some meat eating plants.Take bladderworts (狸藻类植物), a kind of such plant, for example.They appear so small and grow in a quiet pond.“But these are the fastest known killers of the plant kingdom, able to capture a small insect in 1/50 of a second using a trap door!”

Once the trap door closes on the victim, the enzymes (酶) similar to those in the human stomach slowly digest the insect.When dinner is over, the plant opens the trap door and is ready to trap again.

Meat eating plants grow mostly in wet areas with soil that doesn’t offer much food value. In such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years.North America has more such plants than any other continents.

Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers (a container like a bottle) full of nectar (花蜜).

The Asian pitcher plant, for example, has bright colors and an attractive half clos ed lid.Curious insects are tempted to come close and take a sip, and then slide down the slippery (光滑的) slope to their deaths.

Hair like growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes can get to work.A tiny insect can be digested in a few hours, but a fly takes a couple of days.

Some of these pitchers are large enough to hold two gallons.Meat eating plants only eat people in science fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn’t a good place to get a drink.

【解题导语】本文是一篇科普文章,介绍了以动物(主要是昆虫类)为食的食虫草。1.From the first paragraph, we learn that bladderworts can________.

A.kill an insect in a second B.capture an insect in 1/50 of a second

C.be found floating on a quiet lake D.digest a fly in a few hours

2.If the trap door of a meat eating plant is closed, the plant is________.

A.fooling insects into taking a sip B.producing nectar

C.tempting insects to come close D.enjoying a dinner

3.Meat eating plants c an grow in wet and poor soil because they________.

A.can get nutrition from animals B.don’t need much food value

C.can make the most of such conditions D.have developed digestive enzymes 4.What can be captured by meat eating plants for food?

A.A child.B.A dog. C.A little bird. D.A little fish.

How many things can you see in the night sky?A lot! On a clear night you might see the Moon,some planets,and thousands of sparkling stars.

You can see even more with a telescope.And with bigger and bigger telescopes you can see more and more objects in the sky.And you can see those objects in more and more detail.

But scientists believe there are some things in the sky that we will never see.We won’t see them with the biggest telescope in the world,on the clearest night of the year.

That’s because they’re invisible.They’re the mysterious dead stars called black holes.

You might find it hard to imagine that stars die.After all,our Sun is a star.Year after year we see it up in the sky,burning brightly,giving us heat and light.The Sun certainly doesn’t seem to be getting old or weak.But stars do burn out and die after billions of years.

As a star’s gases burn,they give off light and heat.But when the gas runs out,the star stops burning and begins to die.

As the star cools,the outer layers of the star pull in toward the center.The star squashes into a smaller and smaller ball.If the star is very small,the star ends up as a cold,dark ball called a black dwarf.If the star is very big,it keeps squashing inward until it’s packed together tighter than anything in the universe.

Imagine if the Earth were crushed until it was the size of a tiny marble.That’s how tightly this dead star,a black hole,is packed.What pulls the star in toward its center with such power?It’s the same force that pulls you down when you jump-the force called gravity.A black hole is so tightly packed that its gravity sucks in everything-even light.The light from a black hole can never come back to your eyes.That’s why you see nothing but blackness.

So next time you stare up at the night sky,remember:there’s more in the sky than we can see!Scattered in the silent darkness are black holes-the great mystery of space.

【解题导语】每当你抬头仰望天空中闪烁的群星时,你是否知道在广袤的太空中还隐藏着无数我们无法看到的东西——黑洞。本文向读者介绍了这些黑洞的形成原因和过程。5.According to the article,what causes a star to die?

A.As its gases run out,it cools down. B.It has a collision with other stars.

C.It can only live for about a million years. D.As it gets hotter and hotter,it explodes. 6.Which of the following statements is NOT true?

A.Black holes are dead stars. B.Black holes have gravity.

C.Black holes are invisible. D.There is nothing as mysterious as a black hole. 7.What happens AFTER a star dies?

A.It becomes invisible. B.It falls to the Earth.

C.It burns up all of its gases. D.It becomes brighter and easier to see.

8.Why can’t you see light when you look at a black hole?

A.Because most black holes are so far away.

B.Because the gravity of a black hole is so strong that it sucks the light inward.

C.Because as the star’s gases burn,it stops giving off heat and light.

D.Because as a star cools,its outer layers pull in toward its center.

Keys:Ⅰ.单项填空

1.解析:选D。考查交际用语。根据Everyone present will burst into laughter可知选D。fun是不可数名词,前面通常不用冠词。No wonder难怪;No doubt肯定地,想必。

2.解析:选C。考查冠词。success和failure此时都是抽象名词具体化,前面通常要加不定冠词a。a success/failure 在此表示“一个成功/失败的人”。

3.解析:选C。考查短语辨析。thanks to因为,由于。此句用了强调句型It is...that...,强调thanks to ill health。instead of代替,而不是……;in place of代替,取代;in face of面对。

4.解析:选A。考查动词用法。根据答语“不,正相反,我认为它非常有必要”,可知bring up这一动作已发生,故选A。regret doing表示后悔/遗憾做过……(已经做过了);regret to do表示遗憾地要做……(还未做)。

5.解析:选D。考查动词的时态。由该句的时间状语“Ever since Dolly,...in 1997”判断,应用完成时,但ring是瞬间动词,不能与“ever since+过去时(间)的时间状语”连用,故用现在完成进行时。

6.解析:选D。考查动词短语词义辨析。句意:如今在中国每个人都应担负起构建和谐社会的责任。make up

表示“弥补”;take up表示“占据,从事”;open up表示“开放,开辟”;build up表示“使强壮,建造”。7.解析:选A。考查动词辨析。expand不仅指尺寸的增加,还可指范围和体积的扩大。stretch一般指由曲变直、由短变长的伸展;extend指空间范围的扩大或长宽的向外延伸,也可指时间的延长;spread一般指向四面八方扩大或传播。

8.解析:选B。考查过去分词作定语。修饰spacecraft,表示被动和完成。句意:中国成功地发射神舟七号飞船,飞船上配备着精密的科技装置。

9. 解析:选C。考查倍数表达法。表达倍数时应把表示倍数的词放在比较级的前面,由此可判断此项正确,此处是“倍数词+比较级+than”结构。

10.解析:选D。句意:当他遇到这个使人困惑的问题时,他脸上露出了困惑的表情。

Ⅱ.完形填空

1. 解析:选B。上一句提到儿子在一次大火中被严重烧伤,由此可知此处应用recover,表示经过一系列治疗,他“康复”了。假如选择A项,应变成被动形式。

2.解析:选A。本句的前半部分提到医生告诉他六个月内不能再做手术,后半部分解释的是其中的原因,所以空格处表示的是因果关系。

3.解析:选D。由于暂时无法进行手术,他的脸上有一道十英寸长的清晰可见的“伤疤”。下一段前半部分中的scar也是线索提示。cut表示“伤口”;wound多用来表示刀伤或枪伤;injury多指(对躯体的)伤害,损伤。

4.解析:选A。此处是作者在安慰自己的儿子,意在表明如果儿子自己不把伤疤放在心上,“没有人”会留意儿子脸上的伤疤。

5.解析:选C。根据本句中的more可知是进行比较。

6.解析:选B。如果儿子自己不会因脸上的伤疤而烦恼,“其他人”也不会把此事放在心上。此处是泛指其他人。

7.解析:选B。hold one’s head high是固定短语,表示“趾高气扬,扬眉吐气”。此处是介词with的复合结构。

8.解析:选C。此处是作者进行了引申,“事实上”每个人都有伤疤和缺点。after all毕竟;in conclusion 在结束时,最后;above all首先,最重要的是,都不符合所给语境。

9.解析:选B。一些人可能认为“如果”自己的长相、衣着等与众不同,人们就会喜欢自己。as long as只要;even if即使;as if似乎,语意都不恰当。

10.解析:选D。此处与下一段中的car相呼应。其余选项在文章中没有信息支持。

11.解析:选A。此处与上一段中的or dressed differently相呼应,由此可判断应选clothes“衣服”。12.解析:选B。作者认为仅仅凭借外在因素去评价一个人是错误的评判“标准”。means方法,手段;comments 评论;rules规则,均不符合语境。

13.解析:选D。根据本段最后一句可知作者的这位朋友长相“丑陋”。

14.解析:选C。由于此人长相丑陋,人们遇到他时自然会长时间地盯着他看,因此looks“外貌”最符合语境。

15.解析:选C。根据本句后半部分中的内容可知这个人自我感觉“良好”。

16.解析:选D。虽然这个人长相丑陋,却有一颗善良的心,他用大部分的时间去“关心”别人的舒适和福利。inquire打听;ask询问;know了解,语意都不恰当。

17.解析:选B。他的善意感动了周围的人,人们“逐渐”忽视了他的相貌。A项表示“彻底”,过于绝对。18.解析:选D。上一句提到人们不再过于注意他的相貌,由此可知人们“看”到的是他的善良和对别人的关心。

19.解析:选A。作者以自己的一个朋友为例,意在表明人的内心比外貌更加重要,所以要注重自己的“内在”价值。

20.解析:选C。如果你能看到你的内在美,其他与你有接触的人同样可以看到你的“美”。

Ⅲ.阅读理解A

1. 解析:选B。由第一段最后一句话可知B项是正确的。

2.解析:选D。根据第二段内容“Once the trap door closes on the victim,the enzymes...slowly digest the insect”可知它在消化昆虫,即在享受食物。因此D项符合题意。

3.解析:选A。根据第三段第二句话可知,这种植物能够生长在这些地方是因为它们以昆虫为食。所以A 项正确。

4.解析:选C。根据文章最后一句话可知,这种植物可能会捕食小鸟。

B

5.解析:选A。细节理解题。文章第六段讲述了其原因。当恒星周围的气体烧尽时,它便停止燃烧然后死亡。

6.解析:选D。细节理解题。文章只提到黑洞是宇宙中神秘的天体,但并没有说它是最神秘的东西。7.解析:选A。推理判断题。从第七、八段的内容可知A项正确。8.Why can’t you see light when you look at a black hole?

A.解析:选B。细节理解题。根据文章倒数第二段中的“A black hole is so tightly packed that its gravity sucks in everything-even light.The light from a black hole can never come back to your eyes.”(黑洞的密度如此之大,

以至于其重力能吸引一切——甚至于来自黑洞的光永远无法到达你的眼睛)可知答案。

高中英语作业分层设计的思路与应用

龙源期刊网 https://www.360docs.net/doc/504117983.html, 高中英语作业分层设计的思路与应用 作者:李凤善 来源:《课程教育研究》2018年第20期 【摘要】随着我国教育教学改革的实施和素质教育的普及,以学生为主体的教育模式日渐成熟,特别是高中教学,不仅形式多元,课上课下也多以激发学生学习兴趣和主动性为目标。在教学过程中,给学生布置作业是由来已久的帮助学生巩固所学知识的关键环节,对提高学生对所学知识的掌握和记忆能力大有裨益。本文立足于高中英语作业布置存在的问题,重点探究了高中英语作业分层设计的思路和具体应用。 【关键词】高中英语教学作业布置分层设计教学原理应用策略 【中图分类号】G633.41 【文献标识码】A 【文章编号】2095-3089(2018)20-0101-02 每一科目预留的课堂作业和课后作业都是为了加强并巩固学生的课堂学习效果、提高学生对同类知识的掌握能力以及及时延伸课程内容。在我国的教育体系中,小学、初中甚至高中学生对布置作业丝毫不陌生,但是部分学生普遍对其感到厌烦,不愿意做,主要是在于教师布置作业的形式没有激发学生的学习欲望。部分教师受传统应试模式影响,给学生布置的作业使用“题海战术”,很少根据学生的实际学习情况进行分层安排,影响学生学习成绩的提升。 一、高中教师英语作业布置存在的问题 首先,作业形式不够灵活,对学生不具有实用性。布置作业的目的是让学生复习所学内容,温故而知新,但是部分教师将作业看作简单的题海战术,只是为学生订阅一系列试题和资料,然后集中下发给学生。学习好的学生会认为此种复习方式过于单一,没有激发其钻研欲望,学习主动性较差的学生面对如此浩如烟海的试题和资料,更加觉得厌烦,总之,这种复习做法已经失去了其本来的意义。 其次,课程复习方式落后,针对性不强。受应试教育的影响,很多学生学习英语的思维和方式较为固定死板,加之一些英语教师受传统应试教育观念影响较深,不关注学生的学习压力,一味采用落后的复习方法引导学生,久而久之,学生对英语的学习会产生恐惧,甚至一无所获[1]。 第三,教师在设计作业时缺少层次感,很难准确达到教学目的。每一个学生都是独立的个体,学习方式千差万别,学习能力也各有不同,表现在英语学习方面也是参差不齐。因此,教师在布置作业时应该照顾到这个因素,对学生的复习和作业布置进行分层处理。但是目前很多教师显然没有意识到这一点的重要性。 二、高中英语作业分层设计的具体策略

(完整word版)人教版高一英语必修二英语课文原文(2)

Frederick William Ⅰ,the King of Prussia , could never have imagined that his greatest gift to the Russian people would have such an amazing history . This gift was the Amber Room , which was given this name because several tons of amber were used to make it . The amber which was selected had a beautiful yellow-brown colour like honey . The design of the room was in the fancy style popular in those days . It was also a treasure decorated with gold and jewels , which took the country's best artists about ten years to make . In fact , the room was not made to be a gift . It was designed for the palace of Frederick Ⅰ. However, the next King of Prussia , Frederick William Ⅰ,to whom the amber room belonged, decided not to keep it. In 1716 he gave it to Peter the Great. In return , the Czar sent him a troop of his best soldiers. So the Amber Room because part of the Czar's winter palace in St Petersburg.About four metres long, the room served as a small reception hall for important visitors . Later,Catherine Ⅱhad the Amber Room moved to a palace outside St Petersburg where she spent her summers. She told her artists to add more details to it .In 1770 the room was completed the way she wanted . Almost six hundred candles lit the room ,and its mirrors and pictures shone like gold. Sadly , although the Amber Room was considered one of the wonders of the world , it is now missing . In September 1941, the Nazi army was near St Petersburg . This was a time when the two countries were at war . Before the Nazis could get to the summer palace , the Russians were able to remove some furniture and small art objects from the Amber Room . However , some of the Nazis secretly stole the room itself . In less than two days 100,000 pieces were put inside twenty-seven woooden boxs . There is no doubt that the boxs were then put on a train for Konigsberg, which was at that time a German city on the Baltic Sea . After that, what happened to the Amber Room remains a mystery . Recently , the Russians and Germans have built a new Amber Room at the summer palace . By studying old photos of the former Amber Room , they have made the new one look like the old one .In 2003 it was ready for the people of St Petersburg when they celebrated the 300th birthday of their city . A FACT OR AN OPINION? What is a fact? Is it something that people believe? No. A fact is anything that can be proved. For example, it can be proved that China has more people than any other country in the world. This is a fact. Then what is an opinion? An opinion is what someone believes is true but has not been proved. So an opinion is not good evidence in a trial. For example, it is an opinion if you say “Cats are better pets than dogs”. It may be true, but it is difficult to prove. Some people may not agree with this opinion but they also cannot prove that they are right. In a trial, a judge must decide which eyewit nesses to believe and which not to believe. The judge does not consider what each eyewitness looks like or where that person lives or works. He/she only cares about whether the eyewitness has given true information, which must be facts rather than opinions. This kind of information is called evidence. Unit 2 AN INTERVIEW Pausanias, who was a Greek writer about 2,000 years ago, has come on a magical journey on March 18th 2007 to find out about the present-day Olympic Games. He is now interviewing Li Yan, a volunteer for the 2008 Olympic Games.

高一英语必修二课文翻译

高一英语必修二课文翻译 Have you ever wanted to be part of a band as a famous singer or musician? Have you ever dreamed of playing in front of thousands of people at a concert, at which everyone is clapping and appreciating your music? Do you sing karaoke and pretend you are a famous singer like Song Zuying or Liu Huan? To be honest, a lot of people attach great importance to becoming rich and famous. But just how do people form a band? Many musicians meet and form a band because they like to write and play their own music. They may start as a group of high-school students, for whom practising their music in someones house is the first step to fame. Sometimes they may ptey to passers-by in the street or subway so that they can earn some extra money for themselves or to pay for their instruments. Later they may give performances in pubs or clubs, for which they are paid in cash. Of course they hope to make records in a studio and sell millions of copies to become millionaires! However, there was one band that started in a different way. It was called the Monkees and began as a TV show. The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles. The TV organizers had planned to find four musicians who could act as well as sing. They put an advertisement in a newspaper looking for rock musicians, but they could only find one who was good enough. They had to use actors for the other three members of the band. As some of these actors could not sing well enough,they had to rely on other musicians to help them. So during the broadcasts they just pretended to sing. Anyhow their performances were humorous enough to be copied by other groups. They were so popular that their fans formed clubs in order to get more familiar with them. Each week on TV,the Monkees would play and sing songs written by other musicians. However。 after a year or so in which they became more serious about their work,the Monkees started to play and sing their own songs like a real band. Then they produced their own records and started touring and playing their own music. In the USA they became even more popular than the Beatles and sold even more records. The band broke up about 1970,but happily they reunited in the mid-1980s. They produced a new record in 1996。 并非乐队的乐队

新课程理念下高中英语作业的设计

新课程理念下高中英语作业的设计 摘要:针对高中英语作业设计存在的种种问题,结合新时代的实际情况,提出高中英语作业设计应体现层次性、多样性、趣味性、人性化以及网络化的特点,使学生更好地吸收、消化所学的知识,进而大幅度推动高中英语课堂教学效果的提升以及学生英语综合能力的提高。 关键词:高中英语;作业 传统高中英语作业布置存在的问题在学生中做了一系列的问卷调查,从反馈回来的信息总结出传统英语课外作业的布置具有盲目性。教师布置作业仅仅是让学生今天有作业做,忽视学生对本堂课知识的巩固和运用。传统英语教学强调以教师为中心,课堂主要以教师讲授为主,课下作业的布置以教师为中心,忽视学生的主动性和自主性。传统的教学模式和应试教育严重影响学生综合运用语言的能力,学生创新英语课外作业的形式不能即时起效,从而影响到学生创新能力的培养。传统英语课外作业的布置,具有随意性,缺乏系统性。在布置作业时,没有一个完整的体系,训练学生什么能力没有明显表现。传统英语课外作业的布置,具有统一性,缺乏个体差异。班级由每个个体组成,每个学生都是不同的,但是教师却忽视这一点,在作业的布置上千篇一律,

忽略学生的个体差异性。有的学生吃不饱,有的学生吃撑了,这样就忽视了学生的个体差异性,作业布置缺乏层次性。 一、高中英语作业设计思路 英语作业是教师检查教学效果和获得信息反馈的一个重要手段。英语作业设计是否合理、有效,直接影响教学改革的效果以及学生的学习效率。结合新课程理念,笔者提出了如下的作业设计新思路: (1)作业设计要保质保量。传统的英语教学以行为主义心理学为理论基础,认为在其他条件相等的情况下,某种行为练习得越多,习惯形成就越迅速。因此,练习的次数在习惯形成中起重要作用。在行为主义心理学的影响下,大部分英语教师坚信“熟能生巧”,不仅要求学生完成课本的配套练习,还会额外征订各种模拟试题、针对相应模块的强化练习、阅读周刊。在高考的压力下,教师更是争相抢夺学生的课后时间,分发不同地区历年高考真题、各试题编写机构所编写的模拟题,其中不乏含有质量低劣的练习题。这些单调、重复的作业浪费了学生大量的时间和精力,剥夺了学生的课余时间,禁锢了学生主动探究的学习能力和创造力。作业过于繁重,会激起学生厌恶、逆反心理,不仅达不到预期的效果,还可能让学生产生厌学情绪。作业是课堂教学的延伸和补充,能使学生更好地吸收消化所学的知识,是巩固、掌握和深化课堂所学知识必不可少的手段,是培养学生综合

浅谈高中英语作业的布置 作业是课堂教学的自然延续和补充,他能使学生更好地吸收消化所学的知识,是巩固、掌握和深化课堂所学知识必不可少的手段,是培养学生综合运用语言能力的有效途径。教师通过布置作业来检查学生对所学语言知识的掌握和运用情况,从而有效地调整教学重心和策略,进行有效教学。然而,在实际教学中,作业的布置存在种种问题,比如,作业内容大量重复,很少考虑学生的个体差异;作业形式简单机械,缺乏弹性;作业的内容脱离学生生活实际,不能给学生提供创造和自主的空间。据此,我们可以尝试改变作业的设计,变被动为自主,变单一为多样,变乏味为有趣,变低效为高效。 一、关注“层次性”弹性作业 了学生,为了学生的一切”是新课程标准的出发点和归宿。在教学过程中,教师在布置作业时,也因遵循因材旋教的原则,根据学生的个体差异,水平的高低,布置难度不同的作业,让学生根据自己的实际情选择要做的哪个层次的作业。但如果教师的硬性规定往往会伤害学生的自尊心,挫伤他们的学习积极性。在学习完人教版高中英语必修三Unit3 The Million Pound Bank Note后,我布置三个层次的不同作业:A、小组合作分角色朗读课文 B、小组合作分角色朗读,并表演对话。(要求学生自做道具并注意表演的表情到位) C、小组合作自编自演英语生活剧。这种作业源于教材,又高于教材,新颖有趣,能开发和利用课程资源。同时教师要相信学生能认识自我,在各自原有的基础上各有收获,体会到成功的喜悦。这样能使优等生“吃得好”,中差生“吃得饱”,后进生“吃得了”,具有人本化和弹性化。这样学生在做作业的过程中既能培养小组合作及沟通能力,又找到了运用所学知识的乐趣。 二、凸显“趣味性”活动作业 一个欢乐而光明的教学环境的主要途径之一”。因此,教师在设计作业时,不仅要考虑教学的需要,还要充分考虑学生好奇求新的心理特征,善于挖掘语言教学中的“趣”,努力提高作业的趣味性,这样才能牵动学生的注意力,唤发学生内心强烈的学习需要。如Duty Report环节中,让每天值日的1名学生或邀请同学自编自导自演英语对话或英语小品。在教完人教版必修一 Unit1 Friendsh ip后,学生本来对大学和大学友谊很向往,可以主他们上网查找自己理想大学的有关信息并介绍自己想像中的大学友谊,这样学生既树立了远大的学习目标又了解了知识,而且能运用所学知识来进行创造性学习。

高中英语作业设计方案的有效性探究

高中英语作业设计的有效性探究-英语论文 高中英语作业设计的有效性探究江西省奉新县奉新一中魏婷 在教案中,不少教师发现传统的英语作业设计模式存在一些弊端,不仅作业知识面狭窄,作业结构单一、缺乏应用性和灵活性;书面作业多,口头作业少,缺乏交际性;作业设计统一,缺乏个性化和层次性;内容枯燥,多以巩固语言知识点为主要目的,很少注重听、说、读、写等语言技能的训练;作业评价注重结果,忽视过程,缺乏激励;作业的批改刻板单一,作业体现教师意志,缺乏张扬学生个性,已不符合与新课程理念的要求。因此,针对作业设计中存在的问题,结合自身的教案实践经验,笔者对作业设计的有效性方面做了探索与研究,以期不断提高教案质量,促进学生全面发展。一、探究英语作业设计的重要意义(一)激发学生的英语学习兴趣有效的作业设计,应当兼顾不同层次学生的接受水平,如果千篇一律地布置作业,不仅会拉大学生学习的差距,更会使一些成绩落后的学生失去学习兴趣。因此,面对学生水平差异、能力差异和素质差异,依据因材施教和可接受性原则进行有效作业布置的研究。从学生实际出发,有的放矢,充分发挥学生的英语学习潜能,激发学生的英语学习兴趣。(二)促进教师专业成长作业设计是课堂教案的延伸,对促进教师专业成长有重要意义。通过对高中英语作业布置有效性的研究与实践,探索高中英语新教材的作业布置方法,使英语教案质量得到提高,从而促进教师专业成长,提升业务水平。. (三)完善课堂教案的需要普通高中英语作业是英语教案过程中的一个重要环节,是学生课内外学习英语的重要形式,英语作业设计是教案设计必不可少的部

分。对这一主题进行研究主要是我校英语作业的现实状况不尽人意,作业设计并没有像课堂教案设计那样受到应有重视,其设计、辅导和评价成为英语教案的盲区,其有效性的问题很少得到探究。对学生而言,作业是课堂学习内容巩固和运用的反映,体现着学习的过程,能有效地促进学生对教案三维目标的达成;对教师而言,作业是检验课堂教案效果的手段,是有效调整和改善教案内容、教案方法的基本依据之一。二、高中英语作业的设计策略(一)坚持正确原则——适度、层次、趣味课后作业的布置,首先应当坚持适度原则。这就要求作业设计必须强化教案目标,突出教材重点、难点;其次是注重层次性。从教育心理学角度看,学生的身心发展由于先天禀赋以及后天诸多因素的影响存在差异,同样的作业,一般的学生只需要五、六分钟便可完成,而学困生要拖上半小时甚至一小时,所以,要让不同层次的学生都能获得成功的体验,教师必须采取把课外作业分层的策略,让不同层次的学生完成不同的作业;第三是坚持趣味性原则。兴趣是思维的动力,是促进学生乐学的先决条件。如果学生对作业设计感兴趣,便会兴奋并且集中注意力,思维敏捷。作业的设计还应有利于对学生进行思维方面的训练,必须注重启发学生的思维。启发诱导学生运用适当的学习方法达到提高学生的综合运用英语的能力。后,可以让学生查询各国的不同交往方式,LanguageBody 4 Unit 如在上完 让同组学生之间相互合作、模仿。这一活动不仅使学生掌握了相关词汇,而且使学生了解了各国的风俗民情,激发了学生的想象力和创造力,更重要的是让学生认识、了解了朋友之间各自的特长和闪光点以及相互协作配合的重要性,有利于开发学生智力,也利于学生实践能力、创造能力和合作意识的培养,使课外作业与任务型课堂教案融为一体。(二)坚持合理评价——评价、激励、启发可

Unit1 IN SEARCH OF THE AMBER ROOM Frederick William I, the King of Prussia, could never have imagined that his greatest gift to the Russian people would have such an amazing history. This gift was the Amber Room, which was given this name because several tons of amber were used to make it. The amber which was selected had a beautiful yellow-brown colour like honey. The design of the room was in the fancy style popular in those days. It was also a treasure decorated with gold and jewels, which took the country's best artists about ten years to make. In fact, the room was not made to be a gift. It was designed for the palace of Frederick I. However, the next King of Prussia, Frederick William I, to whom the amber room belonged, decided not to keep it. In 1716 he gave it to Peter the Great. In return, the Czar sent him a troop of his best soldiers. So the Amber Room became part of the Czar's winter palace in St Petersburg. About four metres long, the room served as a small reception hall for important visitors. Later, Catherine II had the Amber Room moved to a palace outside St Petersburg where she spent her summers. She told her artists to add more details to it. In 1770 the room was completed the way she wanted. Almost six hundred candles lit the room, and its mirrors and pictures shone like gold. Sadly, although the Amber Room was considered one of the wonders of the world, it is now missing. In September 1941, the Nazi army was near St Petersburg. This was a time when the two countries were at war. Before the Nazis could get to the summer palace, the Russians were able to remove some furniture and small art objects from the Amber Room. However, some of the Nazis secretly stole the room itself. In less than two days 100,000 pieces were put inside twenty-seven wooden boxes. There is no doubt that the boxes were then put on a train for Konigsberg, which was at that time a German city on the Baltic Sea. After that, what happened to the Amber Room remains a mystery. Recently, the Russians and Germans have built a new Amber Room at the summer palace. By studying old photos of the former Amber Room, they have made the new one look like the old one. In 2003 it was ready for the people of St Petersburg when they celebrated the 300th birthday of their city.
