The Arctic will soon be free from ice, expert...

The Arctic will soon be free from ice, experts say. The change is bound to take place, but the global warming and climate change are changing the earth’s landscape (地形) rapidly，causing panic worldwide.

Experts say that the Arctic sea ice is melting (融化) quite faster than expected and it can affect not just the region, but Earth in general. A scientist even says that next year, or maybe the year after that, the Arctic will be free of ice.

Peter Wadhams, a scientist, said that the melting trend led to his statement. “Most people expect this year will see a record low in the Arctic’s summer sea-ice cover. Next year or the year after that, I think it will be free of ice in summer and by that I mean the central Arctic will be ice-free,” Peter Wadhams, director of the Scott Polar Institute in Cambridge, said in an interview with the Guardian. “You will be able to cross over the North Pole by ship,” Peter Wadhams added. He strongly believes that although some pieces of ice will remain, the Arctic basin may be free of sea ice in the next two years starting in the summer of 2017.

Wadhams’ study says that melting sea ice will have a great influence on the planet since the sea ice is more capable of reflecting (反射) sunlight compared to water that can only reflect 10% of the sunlight. Once the sea ice melts, the water can only reflect a small amount of sunlight. This means that the Earth will receive and absorb more sunlight, making the planet even hotter.

The year 2016 has already broken records of the hottest temperature ever recorded and the trend doesn’t seem to show any decrease in global warming. “It doesn’t look like the ice is healing and growing back,” Tom Wagner, NASA’s manager for cryosphere (冰冻圈) research said in a statement.

Like Wadhams, scientists and researchers all over the world are lecturing around to educate people to help lighten global warming that has already changed the planet’s landscape.

A new report says sea ice in the Arctic Ocean is melting more quickly than expected. American scientists say the ice is melting even faster than computer programs had estimated.

Scientists know that climate change has a major effect on the Arctic Ocean partly because sea ice is disappearing. They also know that areas of open seawater are expanding. Such areas are known to take in sunlight and increase temperatures. Scientists say this has helped to cause the loss of the Arctic’s ice cover.

For the study, the American scientists compared eighteen computer programs with observations made by satellites and other instruments. The Intergovernmental Panel on Climate Change used the computer programs to prepare its 2007 estimates of climate change.

The computer programs gave estimates of the amount of ice in the Arctic Ocean in the month of September. September is when the Arctic has the least ice, after the warm, summer months. The computer estimates suggested an ice loss of two and a half percent for every ten-year period between 1953 and 2006.

Newer studies of the Arctic have used information gathered by aircraft, satellites and ships. This information showed a loss of September ice cover of almost eight percent for every ten-year period between 1953 and last year. This means the ice is disappearing about thirty years faster than the computer programs estimated.

The scientists say the programs might not have recognized the full effect of increased carbon dioxide and other gases in Earth’s atmosphere. They say their study suggests the gases may have more of an effect than had been thought.

1.It is reported that sea ice in the Arctic Ocean is melting more quickly than expected mainly because _________.

A. climate change                        B. sea ice’s disappearance

C. seawater’s expansion              D. the loss of the Arctic’s ice cover

2. How did the scientists draw the conclusion that sea ice in the Arctic Ocean is melting more quickly than expected?

A. The scientists have been observing the Arctic Ocean for many years.

B. The scientists have compared the computer programs with observation made by satellites and other instruments.

C. The scientists have figured out many numbers with the help of computer.

D. The scientists have found that the seawater take in sunlight and increase temperatures.

3.If the ice melts at the present speed, by the end of this century the ice loss in the Arctic Ocean will be _________ according to newer studies.

A. 22.5%                B. 35%          C.72%         D. 100%

4.Which of the following is TRUE according to the passage?

A. The figures of the computer estimates are wrong.

B. Scientists study climate change through studying sea level.

C. Newer studies show gases may have more effect on sea ice in the Arctic Ocean.

D. The ice is melting even faster than satellites have estimated.

5.This report mainly warns human to _________.

A. prevent the sea ice in the Arctic Ocean from melting any more

B. pay more attention to the loss of the Arctic’s ice cover

C. take necessary steps to protect the environment of our earth

D. stop summer sea ice in the Arctic from disappearing so fast

Over the past decades, sea ice _____ in the Arctic as a result of global warming.

A. had decreased     B. decreased        C. has been decreasing D. is decreasing

高二英语单项填空中等难度题查看答案及解析

Due to climate change, Arctic ice is breaking up earlier in the spring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.

Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking（减少） ice has also forced more polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed.

In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast（绝食） during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.

1.What is Arctic ice doing earlier each year?

2.What is true of polar bears that are spending more time on land in Alaska?

3.What do polar bears in Hudson Bay do during the summer?

4.In which publication would you most likely find this passage?
