Read this article from a school magazine, written by Wei Hua, who studied in the UK for one year.School life in the UK

Going to a British high school for one year was a very enjoyable and exciting experience for me.I was very happy with the school hours in Britain because school starts around 9 a.m.and ends about 3.30 p.m.This means I could get up an hour later than usual, as schools in China begin before 8 a.m.On the first day, all of the new students attended an assembly in the school hall.I sat next to a girl whose name was Diana.We soon became best friends.During the assembly, the headmaster told us about the rules of the school.He also told us that the best way to earn respect was to devote ourselves to study and achieve high grades.This sounded like my school in China.I had many teachers in the past year.Mr.Heywood, my class teacher, was very helpful.My favourite teacher was Miss Burke— I loved the lesson that she gave in English literature.In our class there were 28 students.This is about the average site for British schools.We had to move to different classrooms for different classes.We also had different students in some classes, so it was a struggle for me to remember all the faces and names.I found that the homework was not as heavy as what I used to get in my old school.However, it was a bit challenging for me at first, because all the homework was in English.I felt lucky, as all my teachers gave me much encouragement and I enjoyed all my subjects: English, History, English Literature, Computer Science, Maths, Science, PE, Art, Cooking and French.My English improved a lot, as I used English every day and spent an hour each day reading English in the library.I usually went to the Computer Club during the lunch break, so I could send e-mails to my family and friends back home for free.I also had an extra French class on Tuesday evenings.Cooking was really fun as I learnt how to buy, prepare and cook food.At the end of term we held a class party and we all had to cook something.I was glad that all my classmates were fond of the cake that I made.Students at that school have to study Maths, English and Science, but can stop studying some subjects if they do not like them, for example, History and French.They can choose other subjects like Art and Computer Science, or languages such as Spanish and German.In the Art class that I took, I made a small sculpture.Though it did not look very beautiful when it was finished, I still liked it very much.I missed Chinese food a lot at lunch.British food is very different.British people like eating dessert at the end of their main meal.After lunch, we usually played on the school field.Sometimes I played football with the boys.Sometimes I just relaxed under a tree or sat on the grass.I was very lucky to experience this different way of life.I look back on my time in the UK with satisfaction, and I really hope too go back and study in Manchester again.Reading strategy: skimming and scanning

We skim a text when we want to get a general idea of what it is about.We look at the titles, the first and last sentence of paragraphs, as well as pictures and charts.to guess what the text is about.When we want to find certain information in a text quickly, we scan the text for key words and phrases, dates, numbers and so on.We do not need to read the whole text word by word.

牛津高中英語模塊一課文翻譯 UNIT1.在英國的學校生活

在英國高中讀一年書對于我來說是一個有趣又刺激的經歷。我對學校的作息時間很滿意因為學校在上午9.00左右開始上課在下午3.30放學。這意味著我可以比往常晚起一個小時因為中國的學校在8.00之前上課。

第一天，所有的學生都去參加了會議。我坐在一個叫戴安娜的女孩邊上。我們很快成了很要好的朋友。在會議期間。校長把有關學校的校規告訴了我們。他還告訴我們在學校贏得別人尊重最好的方法就是努力讀書取得高分。這聽起來就像是我中國的學校。

在過去的一年里我有很多老師，他們每一個人都只教一門功課。海伍德先生是我的班主任。我最喜歡的老師是伯克老師。她是教我們英國文明的老師。在我們的班級里只有29個學生。這是英國學校每個班的學生平均數。我們不得不為了上不同的課程而去不同的教室。在一些教室，我們還有不同的同學，所以記住所有同學的長相和名字是很困難的。

我發現家庭作業也沒有我以前的學校所布置的多了，但是起初它對于我來說是一個挑戰因為所有的功課都是英語。我感到很幸運因為我所有的老師都很樂于助人并且我很喜歡我所有的課程：英語，歷史，英國文明，電腦技術，數學，自然科學，體育，藝術，烹飪和法語。我的英語改善了不少因為我每天都在使用英語并且每天花一個小時在圖書館看英語書。我經常在午餐時間到電腦俱樂部，所以我可以免費回復我家人和朋友的電子郵件。我在周二晚上也有一個額外的法語。烹飪是真的很有趣因為我學會了怎樣去買，準備以及烹飪食物。在學期結束時我們還舉辦了班級派對。我們都烹飪了些東西。當我的朋友很喜歡我制作的蛋糕時我很快樂。

在那個學校的學生必須學習數學，英語和科學，但是可以放棄一些他們不喜歡的科目，比如歷史，法語和藝術。他們可以選擇其他科目例如木工制作，電腦技術或者是像西班牙語德語的語言。在木工制作的課程上我做了一個小桌子。盡管他剛完工的時候看上去不像一個桌子，我仍然很喜歡它。

在午餐時間我也很想中國的食物。英國的食物實在是很不同。英國人在他們主食之后會吃很多的甜點。午飯后，我們經常在學校的操場上玩耍。有時候我也和男孩們一起踢足球。有時候我只是坐在樹下或草地上休息。

能體驗到如此不同尋常的生活方式我感到很幸運，而且我也很希望有一天我還能回來繼續在曼徹斯特讀書。

第五篇：牛津高中英語M5U3兩篇課文

The perfect copy

Scientists have announced that they have cloned the first human embryo.This has caused much debate round the world.On the one hand, some scientists point out that if you clone an embryo, you can produce valuable human tissues----such as bone or lung tissue----that could be used to save human lives.On the other hand, many people, including some scientists, disagree and are afraid that, if mankind toys with nature in this way, we may be on our way to producing a real-life Frankenstein’s monster.Cloning is producing an exact copy of a plant or an animal using its cells.The first mammal to be cloned successfully from an adult cell was Dolly the sheep.She was born in 1996 and died in early 2003, at a much younger age than normal.When she was born, many people were worried that cloning would lead to more diseases in animal world.However, in general the scientists were praised for their wonderful scientific advance.Ian Wilmut, the Scottish scientist who created Dolly, is shocked that some scientists are now considering cloning human beings.Although he researches cloning, his intention has never been to create copies of humans.Instead, he thinks research efforts should concentrate on creating new tissues and organs that can be used to cure diseases like cancer.However, some people believe that cloning human embryos with the intention of destroying them shows no respect for human life.Even though human cloning is causing a lot of anxiety, it is good news for Faye Wilson, a 41-year-old saleswoman who cannot have a baby.“I am anxious to have a child of my own,” she says.“I don’t want to adopt someone else’s child----if I had the chance, I would have a cloned baby right now.”

While cloning human embryos is not legal in many countries, some scientists are already pushing ahead with research in order to produce a cloned human baby.Severino Antinori, an Italian physician, has declared that he wants to be the first to clone a human being.In China, scientists have focused their efforts on cloning animals, as well as cloned tissues to be used in medical treatment.China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.Dear Editor

I believe that human cloning is wrong.If we toy with nature, we will have to deal with the consequences.Who knows what could happen? Human life would just become a crop to be harvested or a product for sale.The human race is using up the Earth’s natural wealth.We should be having fewer babies in order to reduce the Earth’s population, not cloning more.I feel sorry for the lady who cannot have a baby, but I would like to point out that there are man children in the world with no parents who would be delighted to have a mother.Pauline carter

Dear Editor

I would like to comment on your article, “The perfect copy”.I think the scientific advances mentioned in your article are fantastic!I am in complete agreement with human

cloning.After all, scientists have been challenging moral ideas for centuries.Why should we stop them now?

On a personal note, cloning would totally transform my life, seven years ago, my 10-year-old daughter died of heart failure.She was beautiful, cheerful and bright.I miss her every single day.If I had the chance, I would clone her immediately so that I could be with her again.Colin Jake

Project Having a debate

Man and nature

For a long time, our environment has been damaged because humans have been careless.People have harmed nature through agriculture, fishing, hunting and tourism.We further damage the Earth by building new channels in the sea and factories on the land, and by creating pollution with chemical waste.We will some day destroy the planet we live on if we continue in this way.However, if we focus only on conservation, then people may suffer.Not everything that is best for nature is good for people.Would anyone say that development should be stopped in favor of nature? From the point of view of some people, we are only doing what humans have always done, using nature to meet our own needs.Other people argue that such thinking may cause a catastrophe, unless we start to look around and understand how a clean environment benefits us all.After decades of destroying nature and using up natural resources, many developed nations are now concerned about saving nature rather than developing or destroying it.However, many poorer nations must focus on meeting the everyday needs of their people.In doing so, they are using up natural resources at a fast pace.They have not yet seen the effects of the careless use of the environment like many wealthy nations have.Often they do not realize that the choices they make are bad for the environment.Should they be blamed for destroying hundreds of thousands of acres of rainforest if it means a better income for their people? The developed and developing countries of the world need to work together to make sure that people enjoy healthy and happy lives, without the environment around them suffering.It should not be a question of humans winning and nature losing.Humans can only really win by protecting nature.After all, food has to be produced in a healthy, natural system, and we all need clean air to breathe and pure water to drink.It is mankind’s responsibility to find answers that good for everyone, and everything.GM food: hope or danger?

In recent years, there has been great progress in the study of genetics.With this progress,doors have been opened up to technologies that never existed before.While many people are excited about these new technologies, these same technologies frighten others.Nowhere is this truer than with genetically modified(GM)food.There are two ways in which a plant or an animal can be genetically modified.First, new material can be inserted into its DNA to give the plant or animal qualities which it would never have in nature.Second, material can be taken from the DNA of a plant or an animal in order to remove qualities which are not desired.One aim of GM research is to produce food which will make us healthier.So far, this technology has been used to produce plants which are better able to defend themselves against pests and disease.Supporters of GM food argue that GM plants are healthier and have larger harvests.While there has been research in GM animals such as pigs, no GM meat is being sold at present.Many questions have been raised about GM food.No one really knows whether it is safe for animals or humans to eat.Scientists admit that more tests should be done on GM food.Research has been limited to increasing production profits, rather than making sure that GM foods are safe.GM food could therefore be dangerous to eat.There is also a question as to whether GM plants are safe for the environment.Since GM crops are planted outside, they are of the food chain----insects and other animals eat them or use their products, and these insects and animals will be eaten by yet other animals.No one knows what effects the GM material might have on the food chain.Since no one really knows whether GM food is safe, many countries have hesitated to give permission for the production of GM foods, as they would rather be cautious with this new technology.
