Walk through the Amazon rainforest today and you will find it is steamy ,warm ,damp and thick .But if you had been around 15,000 years ago, during the last ice age ,would it have been the same ?For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted(反应)to the cold ,dry climates of the ice ages ,but until now ,no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming . Currently the trees in the Amazon take in around 500 million tons of CO2 each year; equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier ,will it still survive and continue to draw down CO2 ?Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.
Unfortunately ,getting into the Amazon rainforest and collecting information are very difficult .To study past climate ,scientists need to look at fossilized pollen ,kept in lake mud .Going back to the last ice age means drilling deep down into lake sediments (沉淀物),which requires specialized equipment and heavy machinery .There are very few roads and paths ,or places to land helicopters and aeroplanes .Rivers tend to be the easiest way to enter the forest ,but this still leaves vast areas between the rivers completely unsampled(未取样).So far ,only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.

Three months after the government stopped issuing(发放)or renewing permits for Internet cafes because of security(安全)concerns, some cafe owners are having financial(经济的)concerns of their own.
The permits were stopped suddenly three months ago by the government until new safeguards could be put in place to prevent misuse of the information superhighway, but for cafe owners it’s a business breakdown with no fix in sight.
“I handed in a request to open up an Internet café and received the conditions,” said the businessman Obeidallah. “I rented a place in the Sharafiah district at SR45,000 and prepared the place with equipment that cost me more than SR100,000. When I went to the local government after finishing everything, I was surprised to find that they’d stopped issuing permits for Internet cafes.”
Having an Internet cafe without Internet is much like having a coffee shop without coffee. “I’m avoiding closing the place, but it’s been more than three months with the situation ongoing as it is.” Obeidallah said. “Who will bear the losses caused by the permit issue?”
The decision took many cafe owners by surprise. “I asked to open an Internet café, and I was handed a list of all the things that were needed to follow through, such as a sign for the place, filling out forms,” said Hassan Al-Harbi.
“I did all that was asked and rented a place. And after the Haj vacation I went to the local government and they surprised me, saying that there are new rules that forbid the issuing of any more Internet cafe permits and that one can’t even renew his permit. I’ve lost more than SR80,000,” Al-harbi added.
As for the government, officials say a method to deal with it is on the way. But security concerns come before profit(盈利).

Paul Zindel’s death on March 27,2003 ended the brilliant life of a famous writer.
Not only did Paul Zindel win a Pulitzer Prize as well as an Obie Prize for his 1970 play The Effect of Gamma Rays on Man-in-the-Moon Marigolds, but be was one of the earliest writers in the field of contemporary(当代的) literature for young adults(成人). The Pigman, published in 1968, is still one of the most well-known and widely-taught novels in the genre.

Edwards Prize for his lifetime achievements, and later that same year he was presented with the ALAN Prize for his contributions to Young Adult Literature.
