BEIJING, Nov. 25, 2005（Reuters）— China’s home-grown human bird flu vaccine① is at least a year away from hitting the market but tests on humans have been approved by the government, head of the research drug company said on Friday.
Development of the vaccine started last year after bird flu outbreaks in Thailand and Vietnam and animal trials have already been completed, said Yin Wei-dong, managing director of Sinovac Biotech.
“It is not a virus that is spreading from human to human，so we are very optimistic②,” Yin told Reuters in an interview.
The deadly H5N1 made its first known jump to humans in Hong Kong in 1997, killing six people. The virus appeared again in late 2003 and is known to have infected 130 people in several parts of Asia, killing 68 of them.
“It is not decided yet when the human trials will begin. We just got approval on November 22 by the State Food and Drug Administration,” Yin said.
Oregon, Nov. 26, 2005（AP）— The deadly strain of bird flu that appeared in Asia and has already spread to other parts of the world has not affected the Oregon poultry③ industry or consumers, according to Oregon State University researchers.
There are many strains of bird flu that do not usually infect humans. But one strain, called H5N1, has jumped from chickens to humans and is blamed for more than 60 deaths in Asia.
International disease control experts are worried about a worldwide outbreak of bird flu, raising concerns such as whether it is safe to eat poultry.
But Oregon State University researchers say there is no proof that the virus can jump to humans by eating cooked poultry products.
“Consumers needn’t be overly concerned about bird flu,” said Jim Hermes, OSU Extension Service poultry specialist. But he urged consumers to follow standard food safety practices in preparing poultry —including washing hands while preparing food, and proper cooking of poultry meat and eggs.
He noted that a 2003 outbreak of bird virus caused much damage to commercial poultry operations in California but did not get into Oregon because of industry safeguards.
Notes:
vaccine  n. 疫苗
optimistic  adj. 樂觀的
poultry  n. 家禽

　For almost forty years the Empire State Building in New York City was the world's tallest skyscraper（摩天大樓）. The building reaches a height of 1, 250 feet. It has 102 floors. The use of steel frames made its height possible. Steel walls can rise height without needing to be thick. Steel frame construction is strong. All plates are fixed firmly together by metal bolts（螺栓）called rivets （鉚釘）. When set in place, rivets are usuall red- hot. One end is already rounded. A riveter uses a special hammer to shape the other end. Then the rivet cools. It holds the plates firmly. High winds can move this strong building. A wind of a hundred miles an hour has caused it to move almost one and a half inches.

Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value.
The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer — Mauritius was to become the fourth country in the world to issue stamps.
Before the order was filled and delivered, a ball was planned at Mauritius’ Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words “Post Office” instead of “Post Paid” on the several hundred stamps that he printed.
Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue’s rareness and age, collectors have paid as much as ＄16 800 for it.
小題1:Over a century ago, Mauritius _______.
A．was an independent country
B．belonged to India
C．was one of the British colonies
D．was a small island in the Pacific Ocean
小題2:The mistake on the stamps was made _______.

London has become a cycle friendly zone after the launch of a new bike hire scheme. It has been designed to encourage more people to cycle in and around central London.
So how does it work? First you have to sign up to the scheme to be sent a key. The key will unlock one of the bikes, which are kept at docking stations in and around central London. You have to pay an access fee for the key and then you pay as you go, for the length of time you use the bike.
Transport for London, which runs the scheme, is hoping to have 6,000 bikes and 400 docking stations in place by the end of the year. The new hire system is hoping to ease congestion  (擁擠 )  in London and is expected to create up t0 40 ,000 extra cycle trips a day into the city centre. London Mayor Boris Johnston launched the scheme and said London had been 6ifilled with thousands of gleaming machines that will transform the look and feel of our streets and become as commonplace on our roads as black cabs and red buses".
However, there have been a few problems since the scheme was launched last Friday. On the first day some people found they couldn't dock their bike properly and their usage of the bike had not registered. Transport for London did admit they had been expecting a few "teething problems" and have said they wouldn't charge for the first day as a "gesture of goodwill". Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.
Despite the comments, the green-thinking London Mayor still seems very positive about things, saying, "My campaign for the capital to become the greatest big cycling city in the world has taken a big pedal-powered push forwards. "
小題1:. London Mayor Boris Johnston launched the new bike scheme in order to______.
A．reduce the air pollution of the city
B．deal with the city's traffic problems
C．increase employment opportunities
D．encourage the citizens to take exercises
小題2:. If you want to hire a bike, in which order will you do?
a. pay for the key to a bike
b. sign up as a member to get a key
c. cycle in and around central London
d. pay for the bike according to the time you use it
A．b→a→c→dB．b→d→c→a
C．d→c→b→aD．d→b→c→a
小題3:. All the following are the problems of the scheme EXCEPT_____.
A．the high cost to hire a bike
B．docking the bikes properly
C．not registering their usage of the bikes

B
(BBC News April 18) All flights in and out of the UK and several other European countries have been cancelled as ash from a volcanic eruption in Iceland moves south.
Up to 4,000 flights are being cancelled with airspace closed in Norway, Sweden, Finland and Denmark among others.
The UK’s air traffic control service (Nats) said no flights would be allowed in UK airspace until at least 07:00 BST on Friday for fear of engine damage.
Safety group Eurocontrol said the problem could last for 48 hours.
The volcano is still erupting and the wind direction is expected to continue bringing clouds into UK and European airspace for some time to come.
The UK’s airspace restriction was the worst in living memory, a Nats spokesman said. Some 600,000 people are thought to have been affected.
Nats suggested that the restrictions were unlikely to be lifted (解除) after 07:00, saying it was “very unlikely that the situation over England will improve in the foreseeable future”.
Passengers were advised to contact their carriers before travelling.
Transport Secretary Lord Adonis said he was “closely monitoring the situation” and would be meeting with key transport officials on Friday morning.
Experts have warned that the tiny particles of rock, glass and sand contained in the ash cloud from the still-erupting volcano could be sufficient to jam aircraft engines.
The Health Protection Agency said the ash from the eruption did not bring a significant risk to public health because of its high altitude.
However, the British Lung Foundation has warned people with lung conditions to keep their medication (醫(yī)療護(hù)理) with them as a precautionary measure.
These are some of the knock-on effects:
● Eurocontrol says Germany is monitoring the situation and considering partial airspace closures.
● The two main airports in Paris and many others in the north of France are closing. 
● There is severe disruption (崩潰) in France and Spain, where all northbound flights are cancelled. 
● Nats is due to make an announcement shortly as to the arrangements that will be in place
through to 13:00 BST on Friday.
● British Airways offers refunds or an option to rebook after all its domestic flights are suspended.
Flybe announces it has cancelled all flights up until 13:00 BST on Friday and more than 25 services due to run after that.
British sports teams have been hit by travel problems after flights were grounded.
60. What may passengers do on hearing the news according to the passage?
A. They may cancel their international flights.
B. They may contact the airlines before traveling.
C. They may take measures to protect their lungs from the ash.
D. They may stay indoors till the volcanic eruption dies down.
61. Why have some European countries cancelled flights after the volcanic eruption?
A. Because the volcanic ash may make passengers ill.
B. Because people refuse to take the international flights.
C. Because the volcanic ash may jam or damage the engine.
D. Because the flights may be hit by the rocks from the eruption.
62. Which of the following statements is true according to the passage?
A. All the flights are likely to return to normal in 48 hours.
B. British people had experienced a worse airspace restriction before that.
C. Germany is monitoring the situation and considering closing all airspace. 
D. The UK airspace restrictions are unlikely to be lifted in the foreseeable future.
