The snow in Antarctica is turning green and scientists say climate change may be to blame. According to a study at the Cambridge University, microscopic algae blooms (藻类爆发) across the surface of the snow is slowly turning Antarctica’s winter white landscape green. Although microscopic, scientists say they’re able to see the “green snow” from space when the algae blooms all together.
Researchers created a large-scale map of green snow algae along the Antarctic coast using a combination of satellite data and on-the-ground observations over the course of two summers. The study found that the green snow algae bloomed in warmer areas where the average temperatures are just above 0℃ during the southern hemisphere’s (半球的) summer months from November to February.
“As Antarctica warms, we predict the overall mass of snow algae will increase,” said Dr Andrew Gray, lead author of the paper, and a researcher. Researchers say larger blooms of algae can be found north of the Antarctic and South Shetland Islands, where it can spread to higher ground as the snow melts.
The team also discovered some sea birds and mammals influenced the distribution of algae. Over 60% of algae blooms were found within three miles of a penguin settlement. Scientists hypothesize this may be due to their droppings, which act as a “highly nutritious fertilizer.”
“This is a significant advance in our understanding of land-based life on Antarctica, and how it might change in the coming years as the climate warms,” said Dr. Matt Davey in the University of Cambridge’s Department of Plant Sciences, who led the study.

As the coronavirus (冠状病毒) outbreak continues, many Americans are fearful of using public transportation. They are also looking for ways to get exercise without going to a gym. So, it may not be surprising that the pandemic (疫情) has led to a major increase in bicycle sales.
In the US, bicycles at big stores have sold out. And small bicycle stores cannot keep up with demand for “family-style” bicycles: the low-cost, easy-to-ride models. “The bicycle industry is seeing its biggest sales increase since the oil crisis of the 1970s,” said Jay Townley, an industry expert. He compared the sale of bicycles to the rush to buy products like toilet paper at the start of the pandemic.
The rise in bicycle sales is not happening just in the US. Italy has created bicycle paths for the growing number of people who want to avoid public transportation. In London, city officials plan to ban cars from some central roads. Bike shop owners in Manila say demand is even stronger than what they see at Christmas time.
Of course, you can only buy a bicycle if you can find one. In the US, the shortages now mean it may take many months to get a bicycle. High demand is not the only reason for the shortage. Many bicycle factories were shut down to stop the spread of COVID-19. The increase in bicycle demand began in March as countries began to close down. In April, the sale of bicycles increased 200 percent in the US.
Joe Minutolo is the co-owner of Bar Harbor Bicycle Shop in Maine. He said he hoped the increased sales meant a change in the way people think about transportation. “People are having a chance to rethink things,” he said, “Maybe we’ll all learn something out of this, and something really good will happen.”
1.What causes the increase in bicycle sales?
A.Shortage of public transportation.
B.Outbreak of the coronavirus.

D.People’s fear of natural disasters.
2.What change has the pandemic caused in Italy?
A.More bikes are sold than at Christmas time.
B.“Family-style” bicycles are in great need.
C.Cars are banned from some central roads.
D.New bicycle paths have been built.
3.What can we know from Paragraph 4?
A.It’s impossible to buy a bike.
B.Bike factories were closed in April.
C.High demand for bikes began in March.
D.It takes many months to produce a bike.
4.What is Joe Minutolo’s attitude towards the increased sales of bicycles?
A.Doubtful. B.Positive. C.Uncertain. D.Critical.
