British engineers at a company called Reaction Engines, have successfully tested a whole new kind of jet engine, named Sabre, Financial Times is reporting, so that the time of long-distance flight could be halved, or even quartered. Britain’s Orange News says jets with the new engine could fly from London to Sydney in four hours, instead of the usual twelve to sixteen hours and Mail Online adds that new engine not only allows for faster travel but pollutes less and the fuel for it costs less as well.

The secret to the new engine is patented(获得专利) and this new technology very quickly changes air from normal temperature to super-cold temperature. This means the engine can run faster without breaking apart due to overheating, which keeps most modern jets from traveling faster. The engine is air-breathing and use hydrogen as its fuel source. In addition to flying faster, a jet with the new engine would also fly much higher, allowing for an even faster flight in the very thin air. Because of the very high speed produced by the engine and the high altitude, a jet with Sabre in it would not have any windows.

This is the biggest breakthrough in jet technology since the invention of the jet engine, and they expect new aircraft with the new engine to be traveling in the sky in just ten years. They also note that tests of the engine were overseen by the European Space Agency which has now wholly supported the new engine and has even begun talking about booking flight time with future jets that could be used to deliver satellites into orbit around the earth.

This technology is not something that happens overnight. Instead, it is the result of many years’ hard work by thousands of engineers from over seventeen countries. Research has suggested that, with advances in jet plane technology to match the engine, flights could eventually reach speeds of nearly 20,000 miles per hour, making travel to distant parts of the globe as quick and simple as driving across town.

1.Which advantage of jets with the new engine is NOT mentioned?

A. traveling faster　　 B. polluting less

C. costing less　　 D. flying more safely

2.What does the underlined word “it” in Paragraph 1 refer to ?

A. Reaction Engines.　　 B. A long-distance flight.

C. A jet with the new engine.　　 D. Mail Online.

3.The modern jets without the new engine can’t travel faster mainly because ________.

A. their engines can’t stay cool

B. they use a normal fuel source

C. they just fly at very high altitudes

D. their engines can’t allow jets to fly in the thin air

4.The European Space Agency hoped to ________.

A. be in charge of testing the technology

B. play the leading role in jet technology

C. use jets with the new engine to launch satellites

D. buy all the products made by Reaction Engines

The engineer Camillo Oliver was 40 years old when he started the company in 1908.

At his factory in Ivrea, he designed and produced the first Italian typewriter. Today the company's head office is still in Ivrea, near Turin, but the company is much larger than it was in those days and there are offices all around the world.

By 1930 there was a staff of 700 and the company turned out 13,000 machines a year. Some went to customers in Italy, but Olivetti exported more typewriters to other countries.

Camillo's son, Adriano, started working for the company in 1924 and later he became the boss. He introduced a standard speed for the production line and he employed technology and design specialists（专家）. The company developed new and better typewriters and then calculators(计算机). In 1959 it produced the ELEA computer in Italy.

After Adriano died in 1960, the company had a period of financial problems. Other companies, especially the Japanese, made faster progress in electronic technology than the Italian company.

In 1978, Carlo de Benedetti became the new boss. Olivetti increased its marking and service networks and made agreements with other companies to design and produce more advanced office equipment. Soon it became one of the world's leading companies in information　 technology and communications. There are now five independent companies in the Olivetti group — one for personal computers, one for Systems and services, and two for telecommunications.

British author JK Rowling was at the release of her latest Harry Potter book called “Harry Potter and the Deathly Hallows” at the Natural History Museum in London, Friday July 20, 2007.

J.K. Rowling has been spotted at cafes in Scotland working on a detective novel, a British newspaper reported Saturday.

The Sunday Times newspaper quoted Ian Rankin, a fellow author and neighbor of Rowling's, as saying the creator of the "Harry Potter" books is turning to crime fiction.

"My wife spotted her writing her Edinburgh criminal detective novel," the newspaper quoted Rankin as telling a reporter at an Edinburgh literary festival.

"It is great that she has not abandoned writing or Edinburgh cafes," said Rankin, who is known for his own police novels set in the historic Scottish city.

Rowling famously wrote initial drafts of the Potter story in the Scottish city's cafes. Back then, she was a struggling single mother who wrote in cafes to save on the heating bill at home.

Now she's Britain's richest woman - worth $1 billion, according to Forbes magazine - and her seven Potter books have sold more than 335 million copies worldwide.

In an interview with The Associated Press last month, Rowling said she believed she was unlikely to repeat the success of the Potter series, but confirmed she had plans to work on new books.

"I'll do exactly what I did with Harry - I'll write what I really want to write," Rowling said.

46 What is JK Rowling famous for?

47 Which of the following is Not rue about Ian Rankin?

48 Why did Rowling like to write the “Harry Potter stories” in the cafes?

49 What can we learn from the passage?

50 What is the best title for the passage?

Freshers’ Week

In British universities, new students have a special name: they are called Freshers. After their A-level exams, young people in the UK often make a fresh start by going to university. Which can involve leaving their family and moving to a new city. 1..

Freshers’ Week is a chance to make lots of new friends and try out different hobbies. Most universities in the UK have a Union building: a place where students go to have fun. 2. It also hosts various societies, including sports teams, political groups, etc. Students buy a membership to be part of a society and go to social events to meet others with similar interests. Sometimes there are quite a lot of students in lectures so it is difficult to get to know people in class. Therefore, each subject has its own club, such as the English Society and the Philosophy Society.

3. Tours of the town, creative workshops and parties are great ways to socialize with others. Sometimes famous singers come and play concerts especially for the new students of the university. There are also opportunities to go on trips to theme parks or other big cities nearby.

Students often move into “halls of residence” in their first year. 4. This is an excellent way to make friends but sometimes it can be difficult if you don’t get along with your new flat-mates or if the shared area gets very messy.

Freshers’ Week can be quite an exhausting experience because so many activities happen at once. A lot of students feel homesick when they first arrive on campus and keep themselves very busy to avoid feeling sad about leaving their family. Some students use their new liberty to drink a lot of alcohol and eat unhealthy food during Freshers’ Week. 5. However, it is supposed to be the best week of your life, and it is also an opportunity to make friends. Remember that it is only the beginning of your time at university and that you have three years ahead of you.

A. Usually it has shops, bars and even underground nightclubs.

B. They live in apartments with their own bedrooms but share a kitchen.

C. The best part of it is that you can share your interests with people around.

D. In Freshers’ Week, lots of activities are organized for Freshers to meet each other.

E. Then comes the great opportunity to make friends, join clubs and settle into university life.

F. This can cause “Freshers’ flu”: people get ill after a week of late nights and non-stop parties.

G. The first week of university life is called Freshers’ Week and is both an exciting and scary experience.

British scientists have discovered the willow trees planted at an angle could increase sugars for biofuel production.

Willow is a fast-growing species. It is already used to produce fuels for the renewable heating and power market. In future it could also help to produce biofuel to power vehicles. It has been known that when willows growing in the wild are blown sideways, they tend to produce more sugars. But for a while it has not been known why this happens.

Researchers at Imperial College London, led by Dr Nicholas Brereton and Dr Michael Ray of the Department of Life Sciences, have now solved the mystery. When the tree is blown sideways, its genes (基因) produce large numbers of sugar molecules (分子) to straighten the tree upwards.

“This is an important breakthrough. Our study now shows that natural genetic changes are related to these differences. And this could well be the key to unlocking the future for green energy from willow,” said Dr Brereton.

The research was carried out under lab conditions. The willows were grown at an angle of 45 degrees. They were compared to willows which grow naturally straight upwards. The team then looked for the same effect among the willows growing on the Isle of Orkney where strong winds cause the trees to bend at extreme angles. They discovered that the Orkney trees produce five times the amount of sugars found in willows grown in sheltered conditions.

Willow is widely planted across the UK. The results show that biofuel crops such as willows could be grown in climatically changeable conditions where chances of growing food crops are limited.

The study is published in Biotechnology for Biofuels.

1.What may happen when willows are planted in strong winds?

A. They stop growing.　　 B. Few sugars are produced.

C. They try to grow sideways.　　 D. Changes in genes take place.

2.The Orkney willows ________.

A. are unusually rich in sugars　　 B. grow naturally straight upward

C. look taller than ordinary willows　　 D. are stronger than those growing in labs

3.Farmers living in changeable climate _______.

A. use biofuel for heating and power　　 B. are encouraged to grow biofuel crops

C. can plant different kinds of food crops　　 D. should make their willows grow straight

4.Where does this passage most probably come from?

A. A personal diary.　　 B. A travel magazine.

C. A scientific journal.　　 D. A newspaper advertisement.
