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.
B. To safeguard food crops.
C. To protect wild plants from extinction.
D. To help scientists study wild plants.
B. the climate change in this area
C. the large number of Asian elephants
D. human"s large consumption
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
B. Kew Gardens" next goal.
C. Britain"s seed bank.
D. The Millennium Seed Bank Project.
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.

kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for
years. Now researchers say there are three different types of loneliness.
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and
does not require any special, attention. The second kind, situational loneliness, is a natural result of a particular
situation, for example, a family problem, the death of a loved one, or moving to a new place. Although this kind
of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for
more than a year.
The third kind of loneliness is the most severe. Unlike the second type, chronic (长期的) loneliness usually
lasts more than two years and has no specific cause. People who experience habitual loneliness have problems
socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or
nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a person"s social contacts, e. g., friends, family
members, co-workers, etc. We depend on various people for different reasons. For instance, our families give
us emotional support, our parents and teachers give us guidance, and our friends share similar interests and
activities. However, psychologists have found that, though lonely people may have many social contacts, they
sometimes feel they should have more. They question their own popularity.
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and
unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease.
While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very
sad, and sometimes dangerous condition.
B. Just ignore it.
C. Go to see a doctor.
D. Ask your teachers for guidance.
B. we depend on various people for different reason
C. lonely people don"t have many social problems
D. lonely people don"t have many friends
B. Chronic loneliness can cause serious illness.
C. Chronic loneliness can not be overcome.
D. A, B and C are all correct.
B. Loneliness and Diseases
C. Loneliness and Social Contacts
D. Chronic Loneliness
of cholesterol (胆固醇) in children, even those with no family history of high cholesterol. To help your kids
maintain a healthy diet and healthy cholesterol levels, you need to do the following.
Pack their lunches
That way you can at least try to ensure they get something healthy instead of the fried and starchy (富含
淀粉的) food that dominate most school cafeterias. The three most common food ordered in elementary
school cafeterias are ground beef (碎肉), chicken nuggets (鸡肉块) and cheese.
Limit fast food
Set a limit of no more than one or two fast-food meals a month, and when you do make a fast-food visit,
push the salads, plain baked potatoes, and broiled chicken. If the kids must have hamburgers, order them
without cheese.
Forget white
White bread, white rice, white pasta, that is. Serve them peanut butter and jelly on whole wheat bread and
meatballs on whole wheat pasta.
Make it easy
Cut up a bowl of fruit and put is before your TV-gazing kids. They"ll eat it as if it were popcorn (爆米花).
Better yet, turn the TV off and serve the fruit to them after they"ve finished a bike ride around the block.
Set an example
The best way to make sure your kids live a heart-healthy lifestyle is to live one yourself. That could be
more rewarding to see benefits not only to your cholesterol, but to your children"s as well.
B. very tall
C. very thin
D. very fat
B. more than one or two fast-food meals a month
C. fruit instead of popcorn
D. as mush white food as possible
B. a heart-healthy lifestyle
C. a kid
D. a kind of food
B. tell parents how to set an example to their children
C. tell kids the best way to lose weight
D. tell kids how dangerous overweight is
lack basic sanitation.
The combination proves deadly. Each year, diseases related to inadequate water and sanitation kill between
2 and 5 million people and cause an estimated 80 percent of all sicknesses in the developing world. Safe
drinking water is a precondition for health and the fight against child death rate, inequality between men and
women, and poverty.
Consider these facts:
The average distance that women in Africa and Asia walk to collect water is 6 kilometers.
Only 58 percent of children in sub-Saharan Africa are drinking safe water, and only 37 percent of children
in South Asia have access to even a basic toilet.
Each year in India alone, 73 million working days are lost to water-borne diseases.
Here are three ways you can help:
(1) Write Congress
Current U. S. foreign aid for drinking water and sanitation budgets only one dollar per year per American
citizen. Few members of Congress have ever received a letter from voters about clean drinking water abroad.
(2) Sponsor a project with a faith-based organization
Many U.S. religious groups already sponsor water and sanitation projects, working with partner organizations
abroad. Simply putting a single project by a U.S. organization can make safe water a reality for thousands of
people.
(3) Support nonprofit water organizations
Numerous U.S.-based nonprofits work skillfully abroad in community-led projects related to drinking water
and sanitation. Like the sample of non-profits noted as follows, some organizations are large, other small-scale,
some operate worldwide, others are devoted to certain areas in Africa, Asia, or Latin America. Support them
generously.
B. people have no access to clean drinking water
C. women"s rights are denied in some developing countries
D. safe drinking water should be a primary concern
B. overseas sponsors
C. congressmen
D. U.S.-based water organizations
B. donate money to people short of water through religious groups
C. fight against the worldwide water shortage and sanitation problem
D. take joint action in support of some non-profit water organizations
B. A list of non-profit water organizations to make contact with.
C. Some ways to get financial aids from U.S. Congress.
D. A few water resources exploited by some world-famous organizations.

of as being a chicken.
However, one tiger, which lives in an English zoo, turned out to be more cowardly than his keepers could
ever have imagined.
Tanvir, a two-year-old Bengal tiger, got stuck at the top of a new 5m-high activity tower in his enclosure,
after climbing it for the first time.
The branching tower had been designed to provide mental stimulation for Tanvir by testing his ingenuity,
but after scaling the exercise structure in just a few seconds, he lost his nerve when it came to coming back
down.
Tanvir went on to spend nearly two days at the top of the tower trying to pluck up the courage to attempt
a descent.
A spokesperson for the zoo said chat Tanvir had taken half an hour to come down from a smaller structure
only l.5m high previously, and that the taller tower had clearly been too much for him.
"Every time he gets to the edge, he looks out, puts a paw over, and thinks, "no, I"m not doing it!"" said
Samantha Cordrey.
In the end Tanvir"s hunger got the better of his fear, and after almost 48 hours he made his way down in
order to eat.
It appears that Tanvir is none the worse for his experience, but it is not known if he will find the guts (勇
气) to go back up his exercise tower again.
The whole episode only serves to underline the difficulties faced by zoo staff in creating environments that
will stimulate the animals living in enclosed spaces.
"It was made to challenge him but he"s a bit of a wimp," said Tanvir"s keeper.
B. tigers have nothing to do with chickens
C. tigers sometimes feed on chickens
D. tigers are generally not so cowardly
B. The first tower did not have any effect in training the tiger.
C. It is uncertain whether Tanvir will go back up the tower once more.
D. Tanvir enjoyed his stay on the tower so much that he refused to come down.
B. To call on us to protect tigers that are being kept in enclosed spaces.
C. To emphasize the difficulties of creating suitable environments for enclosed animals.
D. To tell readers how to train wild animals, such as tigers.
B. Zoo keepers knew the structure was a bit difficult for Tanvir.
C. Tanvir was the only tiger that was trained by the zoo keepers.
D. All tigers needed training before they were set free from the zoo.
