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.
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.
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
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
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.
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.

I once met a middle-aged stranger who said his money had been stolen at the railway station,so he had no money to go home. He begged for help from passers-by,but they all pretended not to have heard what he was saying and went by quickly. Then he stopped me and wanted me to give him the help. At first I could not accept that because I didn't think he was telling the truth. But when I saw tears in his eyes,I began to believe that he might be in the real trouble,so,just immediately I gave him all the money I had. When he took the money, his face turned red. Before he left,he expressed his great thanks and also said he would give back my money when he reached home.
When I came back to school and told my classmates about my story,they held different opinions. Some of them thought that I did a good deed to have given a hand to the person in trouble,while others said that I was cheated. Some even laughed at me and called me a fool who could not judge things in the right way. Now,I am really confused!

Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut.” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up (蜷伏)with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “In fact, parents are first on the list.” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
“The door to his room is always shut” suggests that the son .
A.keeps himself away from his parents
B.doesn’t want to be disturbed
C.is always busy with his studies
D.begins to dislike his parents
What troubles Tina and Mark most is that .
A.their daughter isn’t as lovely as before
B.they don’t know what to say to their daughter
C.they can’t read their daughter’s mind exactly
D.their daughter talks with them only when she needs help
Which of the following best explains “the wall of silence” in the last paragraph?
A.Teenagers do not talk much with their parents.
B.Teenagers do not want to understand their parents.
C.Teenagers talk a lot with their friends.
D.Teenagers talk little about their own lives.
.What can be learned from the passage?
A.Parents are unhappy with their growing children.
B.Parents have suitable ways to talk with their teenagers.
C.Parents should try to understand their teenagers.
D.Parents should be patients with their silent teenagers.
