Since its invention 100 years ago, plastic , the superstar of the technological age, has become ugly and ungreen . But that’s about to change. An exhibition at London’s Science Museum this week could put it back on the cutting edge of science.
Have you ever hesitated in donating blood? The invention of “plastic blood” might make you feel better.
British scientists are working on the artificial blood as a replacement for real blood in emergency situations. It is made of plastic molecules(分子 ) and can join oxygen and transport it around the body. As a red, honey-like glue , plastic blood can be carried around conveniently . You just add water to make as much blood as you need.
The cells of our body are strict about what molecules the let in and out . For example , if we inject protein or DNA directly into the body, our immune ( 免疫 ) SYSTEM WILL DESTROY IT BEFORE IT REACHES THE CELLS.
To get around this , a British scientist has created drug-carrying plastic balls that fool the body into thinking they are natural. Once inside the cell, their contents are spread out through a small controlled explosion.
Skin transplants are widely done these days. But removing a piece of skin from, say , the bottom to plant it on the face can hurt and be troublesome.
The British company, Celltran, is working on plastic skin. Using plastic, they plan to take a small piece of the patient’s skin and grow it into an extra lay of skin on top of the plastic. a
The plastic feels similar to skin, so skin cells like to grow on it. The plastic then gradually disappears, without any reaction or infection .

The World Trade Organization (WTO), founded on January 1, 1995, aims to encourage international trade to flow as possible, making sure that trade agreements are respected and that any disputes can be settled.
In the five years since its founding, the WTO has become well known as one of the world’s most powerful economic organizations, taking its place alongside the World Bank and International Money Fund.
The system of global rules for international trade, however, dates back half a century to 1948 when the General Agreement on Tariffs and Trade was formed after World War II.
As time went by, it became clear that the GATT had two major drawbacks-the limited areas of trade it covered, and the lack of an effective system to settle disputes.
After seven years of trade talks ending in 1994, the so-called Uruguay Round finally give birth to the WTO, complete with an effective system to settle disputes and new rules covering trade in services and intellectual property.
Even after seven years of talks and 22, 500 pages of agreements, there were still problems, especially the difficulty to deal with areas of agriculture and services, which the member nations agreed to revise in 2000. The WTO, with its head office in Geneva, has 135 members with 30 more waiting to join.
From the passage we know that the GATT stopped working ________.
A. soon after World War II ended
B. a little more than 50 years after World War II
C. just in the year 1994
D. seven years before the Uruguay Round talk
Compared with the GATT, the WTO _______.
A. didn’t pay enough attention to services and intellectual property
B. got its members to sign the agreements more easily
C. has got to many areas of international trade to deal with to work effectively
D. can do better to settle disputes in more areas of international trade
In the new century the WTO will ________.
A. take the place of the World Bank and International Monetary Fund
B. have more members and settle more problems
C. make complete new rules in every area of international trade
D. have new rules covering trade in services and intellectual property

Even British People Can’t Speak English Properly
There are different regional accents across the UK, and a number of regions have several different dialects, that is, they have their own unique vocabulary and grammatical phrases. There were at least six different accents born to London the last time I counted.
Worse than that, it is not just where a person is born in the UK that decides their accent. For example, a language and its accents often vary across class or level of education. Another example is how language can differ among age groups in the UK. The words and pronunciations used by young people in the UK can be radically different compared with those used by adults.
Yoof culture
The word ‘yoof’ is a slang spelling of ‘youth’. Some people consider ‘yoof’ to be a negative term, since its pronunciation is easier and lazier than ‘youth’. Other people see the term as positive, because it describes how young people are creating their own language, concepts and identity. When people find it difficult to understand their children, the children can say more things than without censorship(审查，检查) of their parents. In this way, young people are starting to find freedom, independence and self-expression. They are creating a ‘yoof culture’.
It is not possible to come up with a complete list of words used by yoof. By the time the list was completed, it would be out of date. New words come and go like fashions. However, a few features of the yoof style of language are as follows:
◆instead of saying something like ‘That’s good!’ or ‘I understand’, yoof will use a single adjective like ‘Safe!’, ‘Sorted!’, ‘Sound!’, ‘Cool!’ or ‘Wicked!’.
◆instead of ‘He then said no!’, yoof will say ‘She was like: no!’
◆Instead of ‘She’s attractive!’, yoof will say ‘She’s fine!’ or ‘She’s fit!’
◆Instead of ‘I don’t care!’, a yoof will say ‘Whatever!’.
New social and political language
Certain groups of society feel threatened by ‘yoof culture’ or by the British working classes having more social freedom. As a result, a negative term now commonly used in the UK is ‘chav’. It is insult and is meant to describe someone who is uneducated and anti-social (e.g. ‘He’s a chav!’). A young person who wears a jacket with a hood(风帽，头巾) (after all, it rains a lot in the UK) is sometimes called a ‘hoodie’. It is a negative term and suggests that the young person is interested in committing crime.
Where does that leave us?
Learners of English often feel that the best test of their English is how well they can talk to a native speaker. Yet learners should not worry about communicating with native speakers so much. Research conducted by the British Council shows that 94 per cent of the English spoken in the world today is spoken between non-native speakers of the language. In fact, when we think about ‘international English’, there is no such thing as native or non-native speakers. The UK no longer owns the English language.
