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(灭绝) 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.
1.What’s the final purpose of the Britain’s seed bank?
A. To collect enough money for the project. B. To safeguard food crops.
C. To protect wild plants from extinction. D. To help scientists study wild plants.
2.The wild banana seed in China is in danger because of _______.
A. the expanding of farming work B. the climate change in this area
C. the large number of Asian elephants D. human’s large consumption
3. We can learn from the passage that _______.
A. the seeds in the bank can be used now and then all over the world
B. India and Brazil haven’t joined in the Seed Bank Project at present
C. there is only one seed bank in the world at present
D. the wild plants in places like India and China will never die out
4. What does the underlined word “it” in paragraph 7 refer to?
A. The extinction of plant species. B. The Millennium Seed Bank Project.
C. Britain’s seed bank. D. Kew Gardens’ next goal.
5.Which of the following information isn’t mentioned in the passage?
A. The global partnership of collecting wild plant species.
B. The temperature condition of the conservative wild plant species.
C. The government’s financial support for the seed bank project.
D. Scientists’ concern on the extinct wild plant species.

According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate (互换). The end result is that the opposite sides of the body are controlled by the opposite sides of the brain.
The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in reading, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies.
Theory number two focuses on the asymmetrical nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left.
There is no doubt that all exist in a “right-handed society”, which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instruments for the 96%. Left-handed people make up for the unfairness by being members of an elite (精英) society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci.
1.Which of the following statements is TRUE according to the passage?
A. Left-handed people are better at speaking
B. Left-handed people are believed to have stronger left halves of the brains
C. Right-handed people are cleverer than left-handed people
D. Right-handed people work best with the right side of their bodies
2.Which of the words or phrases is closest in meaning to the word “asymmetrical”?
A. valuable B. not typical
C. not balanced D. negative
3.What can be inferred from the passage?
A. Left-handed people may feel inconvenient in this right-handed society
B. This is an equal society for the left-handed people
C. Most great geniuses are left-handed
D. Left-handed people are considered to be disabled
4. What’s the best title for the passage?
A. Which proves to be the better way to live, right-handed or left-handed?
B. How do left-handed people differ from right-handed ones?
C. Why are some people left-handed?
D. Are left-handed people equally treated in society?

W e all love bank holidays. In the UK, we only get eight bank holidays in one year, and at least five of those occur around Christmas time and Easter time! A bank holiday is a British English term. This is an official day that is decided by the government, when banks, shops and offices close for the day even though it’s a weekday—usually a Monday, and a lot of people have a day off work.
Bank holidays are different in Colombia—firstly, they are called “festivos”. There are twenty festivos for the whole country in one year! In Britain ,people get more holiday allowance(津贴)than Colombians but fewer bank holidays. There can be even more festivos in Colombia, depending on which region of Colombia you live in. This is because different regions have their own holidays. For example, some regions have a patron saint(守护神) in their region, so they have an extra festivo to celebrate that saint.
However, there are some days that are national holidays for historical reasons. There is an Independence Day celebration on July 20 every year. This is just like Bastille Day in France on July 14, or Independence Day in the United States on July 4. Other important festivos in Colombia are :Labour Day, on May 1, and Columbus Day on October 12. Columbus Day is a historical bank holiday that almost every county on the continent of America celebrates. This includes Colombia, Chile, Peru, Argentina, Mexico and the United States. It is a memorialization of the day that the Italian sailor, Christopher Columbus, first reached land on the continent in the year 1492. Many people criticize this day and say it is not something to celebrate because of the way Columbus and his teams treated the people that were already living there.
1.What is a “bank holida” according to the text?
A. An official nationwide vacation.
B. A holiday only for the bank staff.
C. A British traditional religion festival.
D. A celebration for Christmas and Easter.
2.What can we learn from paragraph 2?
A. Colombia and Britain have the same number of festivos.
B. All Colombians have the same number of festivos.
C. Colombians have less holiday allowance than British people.
D. People in most regions celebrate a patron saint.
3.Why do many Americans refuse to celebrate Columbus Day ?
A. Because Columbus wasn’t an American at all.
B. Because Columbus once treated the locals badly.
C. Because it wasn’t Columbus that found America first.
D. Because Columbus didn’t live in the continent of America.
4.What is the text mainly about?
A. A British English term.
B. Bank holidays in Colombia.
C. Important festivos in America.
D. Different bank holidays in the world.

People all over the world have some strange hobbies, and one of the most unusual in Britain is "trainspotting". 1..You'll see the grown.ups standing around a railway stations and other places where trains pass by, and you'll see them taking photos and exchanging notes with each other. So, what are they doing?
2. - the numbers on the front of the trains, or the make and model of the "locomotive (火车头)" -the part of the train which pulls all the other part. In the same way that some people collect toys or stamps, these men collect and exchange all kinds of details about trains and railways.
The idea goes back as far as 1942. That year, a young man named Ian Allan was working at Waterloo railway station in London.3., and quite a lot of the questions he received were very similar. He found himself getting a little annoyed at sending the sine replies to the same questions .so he had a word with him boss. He asked if he could write a brochure giving the answers to the most frequently asked questions. His boss said if he wanted to waste his time on such a project, that'OK.4..So he did. The brochure he wrote was the earliest version of the FAQs (常见问题) you see on websites nowadays.
The first 2,000 copies were all sold in days, and by the 1950s, a million copies of British Railways Locomotives were selling every year. Ian Allan went to become a successful publisher, and got an Order of the British Empire(OBE,大英帝国勋章) from the Queen in 1995.5..
A.But he should do it in his own time
B.The young man spent much time on it
C.They're looking for the trains they've taken
D.Well, they're collecting information about trains
E.It's usually men over the age of 40, but not always

G.It was his job to answer letters from people about trains
