WEEK 15 自然环境（2）

一、完形填空（共20小题；共35分）

A

Too hot Some mountains offer climate animals lots of land. Pikas(兔鼠) like living there. When it gets warm, they like 1 uphill. They look for cooler environments they like better. And pikas aren't alone. A 2011 study found that many mountain 2 move their living place. They move uphill by about 11 meters every ten years since the 1960s.

Scientists think this would be 3 news for the animals. For one, the higher up a mountain they travel, the 4 space that they can live in. After all, mountains look like pyramids, right

In many 5 , animals like pikas and birds may actually get ground when they move uphill, the study shows. Paul Elsen is a scientist. His team published its 6 on May 18 in Nature Climate Change.

Most scientists thought that higher living place for migrating(迁移) animals became 7 and smaller. If it is true, that would mean that many earth-warming animals might run out of their new living place—and face 8 .

But Elsen started to doubt about this while he was studying 9 in the Himalayas. "That's a huge mountain area in East Asia. Such mountain area might actually 10 more living place to some animals that like living in cooler environments," he said.

Scientists in the UK are surprised that so many flowers are in bloom(开花期) this winter. They said that in usual years, between 20 and 30 kinds of flowers and plants are open. However, on New Year's Day, scientists found 368 different kinds in bloom.

Scientists believe so many flowers are in bloom because of climate change (气候变化). Last year was the warmest year Britain has ever had. Dr. Tim Rich told the BBC about his surprising at the number of flowers he saw at the start of this year. He said, "Fifty years ago, it was difficult to find plants in winter. But it seems everything's becoming different." He said some flowers were in bloom five months earlier.

Scientist Rich explained how the weather affects flowers. The flowers are usually killed by the cold in December. He said, "We are now in our fourth warm winter. Usually flowers go away by Christmas but this year it hasn't happened." He added, "But many flowers are still in bloom now, after New Year's Day."

Britain's weather report talked about the climate for last year. It said, "All months except August were warmer than usual years, and this was the warmest year on record for the UK. It was also wetter than usual years for many areas."
