Britain’s seed bank, the only one in the world aiming to collect all of the planet’s wild plant species, has reached its goal of banking 10 percent by 2010.
The Millennium Seed Bank Project, run by Kew Gardens—one of the oldest botanical gardens—will officially deposit the 24,200th species on Thursday, a pink, wild banana from China.
More than 50 countries are now on board with Kew's giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said.                                                                                                                                                            
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds. Its goal is to help protect the planet’s bio-diversity during a time of climate change.
The wild banana seed is under threat of extinction(滅絕) in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human consumption.
Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes—when the species no longer exist in the wild.
It is a race against time, Smith said, because in the last decade alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century.
"It is urgent and it is happening now. An area, the size of England, is cleared of primary vegetation（植被）every year." Smith said.
Because most of the world's food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity.
For Kew's next goal—to collect a quarter of wild varieties by 2020—the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.
【小題1】What’s the final purpose of the Britain’s seed bank?

   （Xinhu）The Expo 2010 Shanghai China formally opened its door to the highly avid public this morning．

Top Chinese political advisor Jia Qinglin and International Exhibitions Bureau President Jean-Pierre Lafon activated the opening device together at a commencement（開始；開端） ceremony．

Celebrations spread across China when Shanghai, the Oriental Pearl, was given the right to host the 2010 World Expo on December 3. Shanghai won the honor after beating rivals from Russia, Mexico, Poland and South Korea.

“I’m very proud of being Chinese,” said Wang Kaibo, a Senior 2 student of the Middle School Affiliated (附屬的) to Beijing Medical University. “The winning of the expo is a victory, not only for Shanghai residents, but for the people of the whole Chinese nation.”

Bidding for the expo shows that China is more confident of playing a more important role on the international stage. It’s competing for large events and the next one could be the World Cup, Wang said.

The World Expo 2010 and the 2008 Beijing Olympics will become the twin shining stars of China’s development over the next 10 years, said experts. The World Expo is known as “Olympics of the economic, cultural, scientific and technological fields.” It is usually held every five years and lasts for six months. The Olympics, World Cup and World Expo are considered three top international events in the world.

China is the first developing country to win the expo bid in the event’s about 159-year history. Not only will it attract more foreign investment to China, but experts say that the half-year-long exhibition will bring at least 70 million visitors to Shanghai.

The expo was first held in London in 1851. It has a history of global influence. The Eiffel Tower, built during the Paris World Expo in 1889, became the symbol of the French capital.Many historic inventions, such as the telephone and airplane, all made their first appearance at a World Expo.

[1]A long red bridge stretches out across water. It runs across the Golden Gate. This is not the entrance to some sacred land，but it is just as magical. The Golden Gate is where San Francisco Bay meets the Pacific Ocean, and at night the scene of the bridge lit up over the water takes your breath away.

[2]Welcome to San Francisco, a place famous for its beautiful parks, hilly streets and lovely beaches. But the bridge is undoubtedly the most well-known symbol of the city. Before its completion in 1937, the bridge was considered impossible to build because of the foggy weather ,powerful winds, and strong ocean currents in the city. However, despite the difficult conditions, the bridge was built in no more than four years. Its total length is nearly 2 kilometers.

[3]San Francisco ranks first on Lonely Planet’S list of best cities to visit in 2013. According to the world’s largest travel publisher, it came top as a result of its cultural mix.

[4]According to the US 2010 census (人口普查）, 21 percent of the city’s population is made up of Chinese people. San Francisco’s Chinatown is the largest outside of Asia and the oldest in North America. Two traditional festivals, the Spring Festival and Mid-Autumn Festival, are the biggest events of the year on the city’s calendar.

[5]If yellow cabs are a key part of New York city life, then the cable car is San Francisco’s equivalent. The first cable car came into public service in 1873, and the slow and noisy vehicle has been a symbol of the city ever since. The cable car network was once damaged by a serious earthquake but, luckily, it has now recovered and provides better views than the subway.

Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake occurs.
Currently, the most modern systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes, Wenchuan earthquake in 2008 and Haiti earthquake in 2010 were not identified early enough for people to flee the area, killing hundreds and thousands of people.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth’s surface.
Scientists performed experiments along California’s San Andreas Fault, an area famous for its earthquakes. Highly sensitive electrical devices are placed about one kilometer below ground in two different places. The devices were able to measure even small changes in air pressure on the Earth’s surface. The scientists say such changes are caused when rocks pushed together, forcing air out of small cracks in the rock.
Two earthquakes hit the area in late 2005. The first took place on Dec.25. A smaller earthquake struck five days later. The scientists noted changes in the earth’s surface about ten hours before the first quake struck. That quake measured three in intensity(強度). They then found similar changes taking place two hours before the other quake struck five days later.
If additional tests confirm the changes are linked to earthquakes, the scientists believe their equipment could be used for early warning systems. A system that provides a warning signal ten hours before a major earthquake could help move people from the area and save lives.
The scientists now hope they can find earthquakes with even greater intensity by placing their equipment deeper in the ground.
71. What’s the best title for the passage?
A.A new way to help predict earthquakes.
B.The earthquakes in the world
C.A better understanding of earthquake
D.Scientists and modern systems of earthquakes
72.If the new method does work, _______.
A.fewer earthquakes will break out
B.rescue workers can save more buried people in ruins
C.a warning can be given at least ten days before the major earthquake
D.fewer people will be killed in an earthquake
73.According to the passage, the devices can predict the earthquake by______
reaching the center of the earthquake
detecting the temperature changes in the earth’s crust
measuring changes in air pressure on the Earth’s surface
recording sound waves under the ground
74.We can infer from the passage that ______.
the equipment is perfect enough to be used in practice
it’s unknown if greater earthquake can be predicted by the equipment
the deeper the equipment is placed, the more accurate the measurement is
the equipment has helped save many lives in the earthquake in Haiti .
75.How many earthquakes are mentioned in the passage?
A. One           B. Two           C. Three         D. Four
