A team of scientists has come up with a plan hey say could help rebuild the Arctic ice cap. The ice cap is a huge area of a ice that covers most of the Arctic Ocean all year round.
Usually, the a ice gets thicker and spreads further each winter, but this hasn’t happened for the past few years. Last month, the ice cap had shrunk to its smallest size since scientists began keeping records of it 38 years ago. The weather in the Arctic has been unusually warm this winter. Some days, temperatures have been 20℃ higher than is normal for this time of year. In March, the temperature was above 0℃ at least one day.
The Arctic ice cap is needed to be rebuilt becau a ice reflects heat and light from the sun back into space. With less ice, the ocean would absorb more heat. The Arctic would warm up even more quickly, and more ice would melt. Without a ice, many animals would lo their natural habitats and could become endangered. It could also affect the weather, with more storms and erosion along the coast.
Dr. Steven Desch and a group of scientists from Arizona State University in the United States think they can help to build up Arctic a ice again. They want to t up wind-powered pumps on the existing a ice. During the winter, the pumps would spread water from the ocean over the surface of the ice where it would freeze and form a new layer of ice. The scientists say that in 10 years, this could add an extra metre of ice to the ice cap.
The plan would require about 10 million pumps and it would be very expensive—about $655 billion. Some other scientists are wondering if the pumps would actually work in vere Arctic conditions. They are also concerned about how the project might affect the environment.
Dr. Desch said his team hoped their proposal would get more people interested in looking for a solution to the problem of melting a ice. He said the only plan people have right now is to try to reduce greenhou gas emissions (排放) from cars and other man-made sources. He and his team don’t think that will be enough to save the a ice, so they’re going to work on their plan and hope that it will give everyone a good start on saving the Arctic ice cap.
41. Why is Arctic ice cap important?

People Who Can’t Count
A recent study has discovered that dyscalculia, the mathematical inability in reading, affects about 5% of children in Britain. There is no simple way of finding out the reason a
nd kids with this learning disability are usually labelled unintelligent.每天改变一点点
So what exactly is this learning disability in mathematics? Unlike most people, dyscalculics cannot recogni three or four objects. 35 For example, they need to count the books on the table before they can say how many there are. In other words, they have to count them one by one. This is where they are different from others. The majority of us, if shown three or four similar things, can immediately recogni them.
36 孕晚期吃什么 They cannot understand, for instance, why two and three makes five. Another problem is not being able to tell which group contains more objects than the other. Experiments have proved that dyscalculics have not developed the part of the brain responsible for processing numbers.
There are also problems with the abstract concept of time for dyscalculics. 37 If your best friend is always late, he might be suffering from dyscalculia. Dyscalculics cannot keep track of time, and they never know how much time they have spent getting ready and how long it will take them to get to work. In addition, rearch has shown that dyscalc
ulics behave oddly in social situations. 38 This poor ability can explain why they never know how much change they are due or what kind of budget they need for their holiday.
On the other hand, dyscalculics are very good at creative arts. People suffering from dyscalculia can become painters or poets. Dyscalculia does not em to delay language acquisition. Dyscalculic children acquire language at the same time as, if not earlier than, most children and have no problem learning to read or write. 39
A. Dyscalculics have difficulties in using numbers at all.
B. This disability scares children away from learning mathematics.
C. They have to go through the routine of counting even a small number of objects.

D. It is quite reasonable for dyscalculics to solve this kind of specific problem at any time.
E. They never know how much they should tip the waiter or they’ve got left after a shopping trip.
