Beijing had its biggest snowfall since 1951. Britain is suffering through its longest cold snap (寒潮) since 1981. And freezing weather is hitting the Deep South, including Florida’s orange groves and beaches.
Whatever happened to global warming?
Such weather doesn’t seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn’t contradict global warming at all—it’s just a temporary phenomenon in the long-term heating trend. “It’s part of natural variability,” said Gerald Meehl, a senior scientist. With global warming, he said, “we’ll still have record cold temperatures. We’ll just have fewer of them.”
Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes. But experts did not connect the current cold snap to climate change.
So what is going on?
“We basically have seen just a big outbreak of Arctic air over populated areas of the Northern Hemisphere”, Arndt said.
In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic and the tropics. This air flow acts like a fence to keep Arctic air restricted. But recently, this air flow has become bent into a zigzag (之字形) pattern, wandering north and south. If you live in a place where it brings air up from the south, you get warm weather. In fact, record highs were reported this week in Washington state and Alaska.
But in the eastern United States, like some other unlucky parts of the globe, Arctic air is coming from the north. And that’s how you get a temperature of 3 degrees in Beijing, a reading of minus-42 in mainland Norway, and 18 inches of snow in parts of Britain. The zigzag pattern arises naturally from time to time, but it is not clear why it’s so strong right now.

It all started at the beginning of this term. At first, Carmen wasn’t really sure what was happening. In class, she had to squint (眯眼) to see the blackboard clearly. As it got worse, she became more and more worried. It was important for her to see the notes and homework the teacher wrote on the board.
In class, she asked for a desk that was closer to the blackboard. One day, her teacher said, “Carmen, I’ve noticed you squinting a lot. Are you having trouble seeing the board?” Carmen shook her head. “I’m fine, Mrs. Cruz.”
At home, she had to sit closer and closer to the television. Her mother noticed her squinting as she watched her favorite shows.
“Tomorrow I will go to see a doctor,” she said firmly. Three days later, Carmen had new glasses. She was told to wear them all the time. “All of the kids at school will think I am a nerd (书呆子)，” she said. “You look just as beautiful with those glasses on as you do without them,” her mother said. But Carmen didn’t believe her.
The next day, Carmen kept the glasses in her pocket as she walked into the schoolyard. Suddenly, she heard her friend Theresa shout. “What’s wrong?” she asked.
“My silver ring is gone!” Theresa cried. Carmen could tell that Theresa was very upset. They all looked for the ring in the grassy area of the playground.
Carmen realized that she could search better if she could see better. She took the glasses out of her pocket and put them on. Everything looked so different! So clear! And a glimmer (微光) of silver caught her eye.
“Here it is,” she shouted. “Thanks Carmen,” Theresa said. “I didn’t know you wore glasses. They look great!” “Thanks,” Carmen replied shyly.
As they walked back toward the school building, two more girls praised her glasses. Carmen smiled. “Maybe wearing glasses won’t be so bad after all,” she thought.According to the text, Carmen_________.

Camping wild is a wonderful way to experience the natural world and, at its best, it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness, it is becoming more and more important to camp unobtrusively(不引人注目地)and leave no mark.
Wild camping is not permitted in many places, particularly in crowded lowland Britain. Wherever you are, find out about organizations responsible for managing wild spaces, and contact them to find out their policy on camping and shelter building. For example, it is fine to camp wild in remote parts of Scotland, but in England you must ask the landowner’s permission, except in national parks.
Camping is about having relaxation, sleeping outdoors, experiencing bad weather, and making do without modern conveniences. A busy, fully-equipped campsite(野营地)seems to go against this, so seek out smaller, more remote places with easy access to open spaces and perhaps beaches. Better still, find a campsite with no road access: walking in makes a real adventure.
Finding the right spot to camp is the first step to guaranteeing a good night’s sleep. Choose a campsite with privacy and minimum influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot. When camping in woodland, avoid standing dead trees, which may fall on a windy night. Avoid animal runs and caves, and possible homes of biting insects. Make sure you have most protection on the windward side. If you make a fire, do so downwind of your shelter. Always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite is found, not made—changing it should be unnecessary.You needn’t ask for permission when camping in .
| A．national parks in England | B．most parts of Scotland |
| C．crowded lowland Britain | D．most parts of England |
The author thinks that a good campsite is one .
| A．with easy access | B．used previously |
| C．with modern conveniences | D．far away from beaches |
The last paragraph mainly deals with
| A．protecting animals |
| B．building a campfire |
| C．camping in woodland |
| D．finding a campsite with privacy |
The passage is mainly about
| A．the protection of campsites |
| B．the importance of wild camping |
| C．the human influence on campsites |
| D．the dos and don’ts of wild camping |
Do you know of anyone who uses the truth to deceive (欺骗)? When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.
For example, some might say, “I just won a hundred dollars on the lottery (彩票). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”
This guy’s a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only one was a winner. He’s really a big loser!
He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half-truths are not technically lies, but they are just as dishonest.
Some politicians often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents(对手) says, “During Governor Smith’s term, the state lost one million jobs!” that’s true. However, and honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.”
Advertisers(广告商) will sometimes use half-truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.
This kind of deception happens too of often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.How much did the lottery winner lose?
| A．One hundred dollars. | B．Two hundred dollars. |
| C．Three hundred dollars. | D．Four hundred dollars. |
We may infer that the author believes people should _______.
| A．buy lottery tickets |
| B．make use of half-truths |
| C．not take anything at face value |
| D．not trust the Yucky Company |
What do the underline words “net gain” in Paragraph 5 mean?
| A．final increase | B．big advantage | C．large share | D．total saving |
What can we know from the example of the Yucky Pill advertisement?
| A．False statements are easy to see through. |
| B．Half-truths are often used to mislead people. |
| C．Doctors like to act in advertisements. |
| D．Advertisements are based on facts. |
Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases（案例， 病例） with his students．The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems．His condition was not improving, and there was not much hope he would live．
Dr.: Mellinkoff asked to see the patient．He introduced himself in Spanish and, in a very gentle voice, asked how he felt．The patient smiled and said everything was all right．Then the doctor asked if he was able to eat．The patient said that he had no desire to eat．
"Are you getting food you like?"
The patient said nothing．
"Do you get the kind of food you have at home?"
The answer was no．
The doctor put his hand on the man's shoulder and his voice was very soft．
"If you had food that you liked, would you eat it?"
"Yes, yes," the patient said．
The change in the patient's appearance couldn't have been more obvious．Nothing was said, but it was easy to tell that a message had been sent and had also been received．
Later, the doctor asked why the Guatemalan man wasn't getting food he could eat．One of the students said, "We all know how difficult it is to get the kitchen to make special meals．"

"I would probably insist," the student said．
"Very well," the doctor said．"You might want to try the same method in the kitchen．It won't be-easy, but I can help you．Meanwhile, let's get some food inside this man as fast as possible, and stay with it．Or he'll be killed by hunger．By the way, there must be someone among you who can speak Spanish．If we want to make real progress, we need to be able to talk with him．"
Three weeks later．Doctor Mellinkoff told me that the Guatemalan man had left the hospital under his own power．It takes more than medicine to help sick people; you also have to talk to them and make them comfortable．The patient had no desire to eat because __________________.

Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. “It’s a well-known pattern,” said lead researcher Frank Stafford at University of Michigan’s Institute for Social Research. “Men usually work more outside the home, while women take on more of the housework.”
He points out that differences among households (家庭) exist. But in general, marriage means more housework for women and less for men. “And the situation gets worse for women when they have children.” Stafford said.
Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005.
Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most – about 21 hours a week.
Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men.
Having children increases housework even further. With more than three, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands’ 10 hours.According to the “well-known pattern” in Paragraph 1, a married man ________.
| A．takes on heavier work |
| B．does more housework |
| C．is the main breadwinner |
| D．is the master of the house |
How many hours of housework did men do every week in the 1970s?
| A．About 28 | B．About 26 | C．About 13 | D．About 6 |
What kind of man is doing most housework according to the text?
| A．An unmarried man. |
| B．An older married man. |
| C．A younger married man. |
| D．A married man with children. |
What can we conclude from Stafford’s research?
| A．Marriage gives men more freedom. |
| B．Marriage has effects on job choices. |
| C．Housework sharing changes over time. |
| D．Having children means doubled housework. |
