When you run, you put force that is equal to ...

When you run, you put force that is equal to three times your body weight on your feet. The human foot contains twenty muscles（肌肉）. This means that there is a lot that can go wrong when you run.

Most sports have some kind of running or jumping. So experts（专家） at many shoe companies work hard to design good sport shoes. First, a designer enters a plan for a shoe into a computer. Engineers then improve the design. A second computer designs a model for the shoe. Then a few pairs are made. Next, the shoe is tested.

Different kinds of sports shoes are made for different uses. Some are made to help marathon runners save energy during a race. Some are made for the stop-and-go kind of running tennis players. But all sport shoes have one thing in common: they are designed to help people’s feet comfortable during sports. Today, nearly every sport has its own special shoe designed for just the kind of running that sport requires.

If you want to see climate change, head north and keep going until you run out of globe. That is easier said than done. The Arctic (北极) is home to few people and covered in ice much of the year. But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else.

In September, scientists announced at the National Snow and Ice Data (数据) Center that Arctic summer sea ice had fallen to its second lowest level since 1979, and probably long before that. The Arctic has lost an area of ice greater than the area of all U.S. states east of the Mississippi River. And what ice remains appears to be getting thinner and weaker.

Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork. “There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area,” they say.

The changes happening in the Arctic are a warning for the entire world .　 As polar expert Walt

Meier puts it, “What happens in the Arctic doesn’t stay in the Arctic.”

Some scientists worry that Arctic sea ice may be going from a downward spiral (螺旋线) to a “death spiral”, one from which there is no escape. As more ice melts (融化), more dark open water appears. The darkness absorbs (吸收) more heat, which speeds up the pace of melting.

Until recently, many scientists thought it might take until the end of the century for the North Pole to become completely ice free during the summer. Now some believe it could happen by 2030 or even earlier. “The melting is happening faster in the real world than it has in the models,” says Nick Toberg.

1.The purpose of the first paragraph is to tell readers __________.

A. it’s difficult to arrive at the Arctic

B. it is too cold for people to live in the Arctic

C. what caused the climate change in the Arctic

D. we can see the most obvious climate change in the Arctic

2.From the second paragraph we can learn Arctic summer sea ice __________.

A. is still decreasing

B. began reducing in 1979

C. fell to its lowest level in September　

D. is equal to the Mississippi River

3.What does the underlined sentence in Paragraph 3 mean?

A. The changes don’t affect the Arctic at all.

B. The changes will only happen in the Arctic.

C. The changes happening in the Arctic will stop.

D. The changes will also affect other parts of the world.

4.Nick Toberg may agree that __________.

A. the ice in the North Pole will stop melting

B. the ice in the North Pole is melting faster than expected

C. the ice in the North Pole will melt before 2030 or even earlier

D. the ice in the North Pole will not disappear until the end of the century

高一英语单项填空中等难度题查看答案及解析

When I was 18, I had a motorbike accident that put me in a coma for three months. The doctors said there was little chance of my coming out of it, but my identical twin, Marcus, didn’t believe them and carried on talking to me. My first words when I came to myself were, “Hello, Marcus. ”Even though I had no memory of my own name, or that the woman crying at my bedside was my mother, I knew Marcus immediately; it was like a genetic(遗传的)memory. just felt close to him.

As weeks went by, I still could remember nothing before the accident. Marcus was the only person I could relate to.

I had to relearn everything, and Marcus helped me. Because of my twin I wasn’t scared of having lost my memory; I believed everything he said. He became my memory, telling me about my school, friends, previous girlfriends and holidays, showing me family photographs, and telling me how perfect I was.

With his encouragement I slowly recovered and tried to become the person everyone around me loved. Then years later, when my memories flooded back, I learned that I was anything but perfect—I was troublesome, selfish, and now very angry with Marcus for having lied to me.

But finally I understood. Out of love, Marcus had chosen not to tell me about my dark side. He wanted me to have a fresh start—and in fact I had one. Thanks to him, I was able to get married and have kids. I’m 46 now, and feel as if I’m in the third stage of my life. I know all there is to know, and wouldn’t want it any other way.

1.Which of the following words best describes Marcus?

2.According to the text, the author_____.

3.How did the author feel when he first got his memories back?

4.What was the author’s purpose in writing the text?

5.Which of the following would be the best title for the text?
