(2010年朝阳十二校第二次联考)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，the seeds can last for thousands of years and 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.

One possible version：

Dear_editor，

Nowadays，there exists an increasingly severe phenomenon that teenagers don’t show respect to their parents. As we can read in newspaper or watch on TV，some teenagers quarrel with parents，some talk back and some even resort to violence. As to this problem，I’d like to offer several proposals as follows.

Initially(Firstly)，we should realize that it’s our parents who give us lives. Without parents，we can not live in this world. Therefore，the importance of respecting our parents can not be too overemphasized. What’s more，it goes without saying that we have to remember the birthday of our parents，when we can express our gratitude to them. None the less (Meanwhile)，respecting our parents should be done from every detail. Just as a proverb goes，“Piety is above all.(百善孝为先。)”

To sum up，respecting parents is our traditional virtue in China. No matter how old we are，it’s a priority to respect our parents.

Yours，

David
