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. 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 |
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 |
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. |
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 |
第三部分：阅读理解（共20小题，每题2分，满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters(爬行生物) like to do the same thing!
Winter is the time when bugs (虫子) invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.
Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There’re different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn’t when the temperature drops.
They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there’s each day. They use that to tell them when to shut down. Bugs are cold-blooded, meaning that their inside temperature is the same as the outside. They can’t move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.
They’re looking for protection. These guys have been doing this for 300 million years, so they don’t really know they’re coming into your house. The home is a recent event in terms of their evolutionary behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don’t care about humans.

“Love your neighbor as yourself”is a saying familiar to most of us. It means that you must have he ability to love and accept yourself in order to form and keep satisfying relationship with others self-esteem means accepting yourself for who you really are, and believing that you are indeed a worthwhile person who is deserving of love and respect from others.
Self-esteem is our sense of how good we feel about ourselves. It is based on our judgment of ourselves, not on other people's assessment, but simply on our own. Our self-esteem is not dependant on our talent. Some very ordinary people feel very good about themselves, while other extraordinarily high achievers hold low opinions of themselves.
Self-esteem is the primary key to long-term stress management. Why? The first three sources of stress are: predictable life event, unexpected changes and build-up of daily stresses, These are much easier to handle when we believe in ourselves, A positive, healthy self-esteem gives us the “hardiness”(强健) to deal with the difficulties of life, and to see them as challenges to be met, rather than threats to be feared.
The forth category of stress is entirely the result of a low self-esteem. It is the category of stress that is most common and tiring over the long run. This kind of stress cannot be overcome, or even changed, until the self-esteem problems that cause it are corrected.
Learning to love yourself for who you are is the key to overcoming stress. Self-esteem comes form the self, and cannot be promoted by others. A person who feels that his self-esteem comes from the approval of those around him or her is bound to self-destruct(自毁), One cannot keep the level of “performance” required to please everyone else, especially if that performance disagrees with who you are and is simply a facade that makes you popular with the world. When the applause is gone, there is nothing left.
Only those who can feel the strength of knowing who they are and those who can feel good about that will survive the stresses of life. Self-esteem is the basis of contentment and positive living.What is self-esteem?
| A．A kind of positive lifestyle. |
| B．The impression we have on other people. |

In February 2006, Lydia Angyiou and her two sons were walking through their village in northern Canada．The sound of children shouting made her turn around．To her horror, Lydia saw a 700-pound polar bear behind her eyeing her seven-year-old son．Getting between the bear and her child, Lydia yelled at the children to run away．She then began hitting and kicking the animal as hard as she could．A neighbor who heard all the noise came and shot the bear．But everyone agreed it was Lydia who had saved her children's lives．A local policeman described it this way: “…I guess when your back is up against the wall…we come up with super-human strength．”
Where does this “super-human strength”，courage and quick thinking come from? Experts say it comes from stress! In stressful situations, the body releases chemicals that prepare it to take action．These chemicals give people the speed and strength they need to fight danger or run away from it．
When we think of stress, we usually think of its negative effects．Studies, though, show that moderate levels of stress are actually helpful．In fact, the way we perform is usually affected by the amount of stress we feel．
Stress causes the brain to release adrenaline（肾上腺素）which in turn increases our energy and excitement．The chemical gives us clearer minds and helps us to do more．This is why some people say they work better under a deadline．
Adrenaline that is not released for long periods of time can cause us to increase and strengthen our abilities instead of weakening them．We sometimes turn out our very best work when we push ourselves to the limit．Stress can also make us more confident．Handling small amounts of stress now prepares us for handling serious situations in the future．Who knows? Today's stress may even prepare for the next polar bear that comes along!In the first paragraph, the case of Lydia Angyiou is mentioned to ______．
| A．introduce the topic to be followed |
| B．praise Lydia Angyiou for her bravery |
