When I was going home to India last year, I called up my mother to ask if she wanted anything from China,

　　 When India had not opened up its markets to the world, I carried suitcase loads of dark glasses and jeans. Thankfully, we can get all these anywhere in India now.

　　 Still, her answer surprised me: “Green tea.”

　　 As long as I can remember she didn’t even drink Indian tea.

I dutifully bought a big packet of Longjing and headed home to hear the story. My mother and her brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all illnesses.

At the turn of the century, China was not really familiar to the average Indian. It was a strange country.

　 How things change! And how soon!

　 Now every town of any size seems to have a “China Market”. And everyone is talking about China.

The government of India has planned to send a team to China to see how things are done. A minister once said that India must open the doors for more foreign investment(投资)and such a step would “work wonders as it did for China”.

But it’s a two-way street. I just heard about a thousand Shenzhen office workers who have gone to Bangalore to train in software. Meanwhile, all the IT majors are setting up a strong presence in China.

No wonder that trade, which was only in the millions just ten years ago, is expected to hit about US$15 billion for last year and US$20 billion by 2008, a goal set by both governments.

No wonder, my colleague wrote some weeks ago about this being the Sino-Indian(中印)century as the two countries started on January 1 the Sino-Indian Friendship Year.

But what is still a wonder to me is my mother drinking Chinese tea.

“The world’s oceans are slowly getting more acidic.” say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.

The lowering of the waters’ PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.

These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change. “This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere,” said Dr Caldeira. “And we predict the amount of future acidity will exceed(超过) anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小行星) impacts.

However, it is not absolutely clear what that means for ocean life. Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes. Coral reefs(珊瑚礁) and other organisms whose shells contain calcium carbonate(碳酸钙) may be particularly affected if the water’s acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH.

In recent years some people have suggested storing carbon dioxide from power station in the deep ocean as a way of dealing with global warming. But Dr Caldeira said that such a strategy should now be re-considered. “Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing --- because in releasing CO2 into the atmosphere we warm the planet, and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.”

答案：63-66 CBCA

D

I have a friend who lives by a three-word philosophy: Seize the moment. Just possibly, she may be the wisest woman on this planet. Too many people put off something that brings them joy just because they haven’t thought about it, don’t have it on their schedule, don’t know it is coming or are too strict to depart from their routine.

I can’t count the times I called my sister and said, “How about going to lunch in half an hour?” She would gasp and stammer (结结巴巴地说), “I can’t. I have clothes on the line. My hair is dirty. I wish I had known it yesterday, I had a late breakfast, and it looks like rain.” And my personal favorite response: “It’s just Monday.” She died a few years ago. We never did have lunch together. From then on, I’ve tried to be a little more flexible.

Life has a way of going faster as we get older. The days get shorter, and the list of promises made to ourselves gets longer. One morning, we awaken, and all have to show for our lives is repetition of “I’m going to” , “I plan on” and “Someday, when things are settled down a bit.”

When anyone calls my “seize the moment” friend, she is open to adventure and available for trips. She keeps an open mind on new ideas. Her enthusiasm for life is contagious. You talk with her for five minutes, and you’re ready to trade your bad feet for a pair of Rollerblades and skip an elevator for a bungee cord.

My lips have not touched ice cream in 10 years . I love ice cream. The other day, I stopped the car and bought a triple-decker. If my car had hit an iceberg on the way home, I would have died happily.

Now ... go on and have a nice day. Do something you WANT to … not something on your SHOULD DO list.
