The sun rises above the Artic Ocean (北冰洋). Across the frozen sea, a white bear moves slowly.

The bear stops and sways (摇晃) his head from side to side. There is nothing to see but endless ice and red sky. Then his powerful nose senses what his eyes cannot: a beluga whale is nearby.

The bear follows the smell and spots a large hole in the ice where a small white whale is swimming. He silently walks towards the hole, then stops, standing still. The whale does not see the bear, whose white fur makes him appear invisible (看不见的) against the ice.

Finally, the whale swims close to where the bear is waiting. With terrifying speed, the bear comes to life and moves towards the whale. In a moment it is over, and the bear eats his first meal in nearly a week.

Polar bears rule the frozen sea, but their ancestors weren’t always built for ice and snow. The first Arctic bears were brown bears, a species that includes grizzly bears. They came to the icy north over a hundred thousand years ago.

No one knows for sure why these bears traveled to such a cold place. Scientists think they might have wandered north looking for food. Maybe they became trapped by glaciers and couldn’t leave. Whatever the reason, the bears never should have survived.

But they did. They got used to their new environment. Their bodies changed. Their behavior changed, too. Eventually, the bears developed into an entirely new species: the polar bear. You can see some of the characteristics that polar bears developed to survive.

Sadly, these characteristics may now threaten the polar bear’s survival. As sea ice melts due to global warming, polar bears are frequently forced to come ashore (在岸上). They are poor hunters on land, which means they often go a long time between meals. The polar bear, king of the Arctic, is now classified as a threatened species.

Although the future of the polar bear is unknown, the tale of two bears continues. As temperatures rise, grizzly bears have been spotted moving north into polar bear territory (领地). These long-lost cousins, once forced apart by nature, are coming back together again.

1.What can be inferred about the white bear mentioned in the first four paragraphs?

A. It is noisy.    B. it is smelly.    C. It is starving.    D. It has good eyesight.

2.Why are polar bears struggling to survive?

1. C 2. B 3. C 【解析】 这是一篇说明文,主要介绍了由于全球气温变暖使冰川融化,北极熊因此受到威胁,而灰熊也开始往北迁移,侵入北极熊的领地。 1.推理判断题。前四段主要讲述北极熊捕食的过程,根据第四段的In a moment it is over, and the bear eats his first meal in nearly a week. 可知,北极熊一周没有吃到东西了,由此推断出北极熊出于饥饿状态,故选C。 2.推理判断题。根据第八段的As sea ice melts due to global warming, polar bears are frequently forced to come ashore (在岸上). They are poor hunters on land, which means they often go a long time between meals. The polar bear, king of the Arctic, is now classified as a threatened species 可推断出,全球气温变暖,冰川融化,它们被迫上岸,没有了捕食之地,故选B。 3.主旨大意题。文章主要讲述了北极熊是怎样由灰熊变来的,以及随着全球气温变暖北极熊面临着生存威胁,结合四个选项,选项C:北极熊黑暗的过去,最合题意。故选C。

“Hey, how are you doing? I’m Courtney. What grade are you in? What’s your favorite book? Elephant and Piggy? Yeah, I got it.”

If you thought you’d walked into a library with a greeting like that, you wouldn’t be too far off. In fact, you’ve entered the workplace of Courtney Holmes, the Storybook Barber.

Two years ago, Dubuque, Iowa, held its first yearly Back to School Bash, offering needy families an opportunity to learn about free resources in the community. Holmes agreed to participate. Saturday was his busiest haircutting day, but he chose to donate his time and give free haircuts to underprivileged kids so they’d look sharp on that first day of classes. But then he had a lightbulb moment(突然醒悟的一瞬): “The kids should earn their free haircut by having to read a book to me,” Holmes said.

The idea was so popular that he continued it for the next two years. Five-to ten-year-old boys would grab a favorite book, settle into the barber chair, and read aloud while Holmes cut their hair. If they stuttered(结结巴巴) over a word, Holmes was there to help.

After the haircut, they’d review the book, from the characters and vocabulary to the themes --- just like in school, only more fun.

Holmes admits he, too, benefits from the free snip-and-reads.

“There was this seven-year-old Bob, who struggled through his book, stuttering over words even though he didn’t have a stutter,” said Holmes. He had the boy take the book home and practice. When the child came back a few days later, “He read it with no problems. That inspires me.”

Holmes and his family have recently moved from Dubuque to a Chicago suburb. When they get settled, he plans to continue his role as the Storybook Barber. “The way the world is today is with guns and violence,” he says, “it’s a safe haven for the kids, to come to the barbershop and read books.”

1.What does the underlined word “underprivileged” in Paragraph 3 mean?

A. Unruly.    B. Poor.    C. Intelligent.    D. Unusual.

2.What did Holmes say about Bob?

A. He fired his enthusiasm.    B. He gifted him a new book.

C. He preferred to read alone.    D. He had a language disability.

3.What can we infer about Holmes from the last paragraph?

A. He showed great concern for kids.    B. He faced serious money problems.

C. He had an excellent sense of humor.    D. He built a shelter for homeless kids.
