“The new Arctic Report Card tells a story of widespread and continued effects of a warming Arctic，” said Jackie Richter-Menge of the US’s Cold Regions Research and Engineering Laboratory.
“This isn’t just a climatological (气候学的) effect. It impacts the people that live there，” she added.
Scientists concerned about global warming focus on the Arctic because that is a region where the effects are expected to be felt first， and that has been the case in recent years.
There was a slowdown in Arctic warming in 2009， but in the first half of 2010 warming was near a record pace. The monthly readings were over 4 degrees Celsius above normal in northern Canada， according to the report card. The report card was prepared by 69 researchers in eight countries.
Researchers said last winter’s big snow storms that struck some Northern countries were tied to higher Arctic temperatures.
“Normally the cold air is bottled up in the Arctic，” said Jim Overland of the US National Oceanic and Atmospheric Administration. “But last December and February， winds that normally blow west to east across the Arctic were instead bringing the colder air south，” he said.
“As we lose more sea ice... warming in the atmosphere can create more of these winter storms，” Overland said.
There is a powerful connection between ice cover and air temperatures， Richter-Menge explained. When temperatures warm， ice melts. When ice melts it shows darker surfaces underneath ， which absorb more heat. “That， in turn， causes more melting and on the cycle goes，” she said.
In September the Arctic sea ice extent was the third smallest in the last 30 years， added Don Perovich of the US Army Laboratory. He said the three smallest ice covers have occurred in the last four years.

However， the study author Dr Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend， and people with small heads should not automatically believe they are less intelligent. For instance， Albert Einstein’s brain was “not particularly large”， McDaniel noted. “There’s some relationship between brain size and intelligence on the average， but there’s plenty of room for exceptions，” he said.
Interest in the relationship between brain size and intelligence grew in the1830s， when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was “an unquestionable connection between the size of the brain and the mental energy displayed by the individual man”. Since that statement， scientists have conducted numerous studies to determine if Tiedmann’s assertion was， in fact， correct. Most studies have looked into the link between head size and intelligence. More recently， however， researchers have published additional studies on brain size and intelligence， measured using MRI scan(核磁共振成像扫描).
For his study， McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average， people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men， and in adults than in children. McDaniel notes in the journal Intelligence.
McDaniel is not sure why the relationship was stronger for adults and women. “Other research has shown that women， on the average， tend to have smaller brains than men， but score just as well—if not higher—in tests of intelligence，” he said.
McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-sized people who are highly intelligent，” he said， “But， on the average， the relationship holds.”

Most Americans prefer to have a lot of eye contact when they are talking with someone. When a person doesn’t make eye contact with them, they tend to think that the person is hiding something or the person doesn’t believe in himself/herself.
When you are having a conversation and you want to leave a friendly impression, be sure to keep looking at that person frequently while you are talking. If it really bothers you to look directly into another person’s eyes, you can gaze generally at, not above, the eyebrow area or the bridge of the nose; this is close enough to the eye region that you will appear to be looking at the person’s eyes. But neither the hair or the shoulders have the same effect. Don’t stare at other people too intensely, otherwise, you will look aggressive(攻击性).
Keep the majority of your focus on the other person. If you glance around the room too much, or look too frequently at other people, your conversation partner may guess that you are looking around for someone else you would rather talk with.
You can lighten your nervousness by smiling more often, nodding, and by gazing at the entire face as well as the eyes. In addition, you can frequently look away for very short periods.
When people get the sense that you are really paying attention to them, they will be much more likely to want to have conversations with you!
小题1:Which of the following is NOT the impression left by those who don’t make eye contact during the talk?
| A．They are not telling the truth. | B．They are bored with the partner. |
| C．They are lacking in confidence | D．They are angry and ready to attack. |
| A．hair | B．shoulders | C．the bridge of the nose | D．area above the eyebrows |
| A．looking away during conversation should always be avoided. |
| B．looking at a person frequently can give him/her a good impression. |
| C．many Americans feel like being stared at for a long time. |
| D．all successful people are good at making eye contact. |
| A．How to make yourself socially successful |
| B．How to use eye contact to make a good impression |
| C．How to make friends with the people around you |
| D．How to leave a good impression during a talk |
A survey on the reaction to Wang’s death, conducted by Tencent, which runs China’s most popular instant-messaging service, received more than 600,000 responses, as of press time Monday．Forty-one percent of respondents expressed sorrow over her death, saying, "It’s a pity she died at such a young age．" Some 31 percent said she should have been more cautious and less vain, while 10 percent were enraged at the hospital that conducted the surgery．The remaining 18 percent were indifferent．
A common thread of online discussion is why someone considered beautiful was so dissatisfied with her looks．Some netizens said Wang was a victim of society’s unrealistic ideal of beauty: double eyelids, an aquiline nose and the pointed chin typical of Western celebrities．Others said her death underscores the limits to which people will go to achieve fame and fortune．Young people, see cosmetic surgery as the key to wealth and love．
"They want to improve their appearance to find better opportunities at work and in marriage," says Ding Xiaobang, a plastic surgeon with the Peking Union Medical College Hospital．"We’re living in a highly competitive society．People regard appearance as a weapon and a means of empowerment…Most of them tell me, ’I don’t care how much I spend, just make me look beautiful’．" In the past decade, Ding says he Has seen a growing number of patients, like Wang Bei, who are young and naturally good-looking．The surgeon attributes this trend to people becoming richer, the standards of beauty changing, competition and frustration．
"Some are frustrated with life and use surgery as a way to try and recover," lie says．
The surge in demand for plastic surgery has resulted in a rise in the number of unauthorized business establishments and surgeons conducting such procedures．
Meanwhile, experts say, young and beautiful people who still seek plastic surgery need to address their self-awareness issues and be more accepting．
“They’ve built their identity around the admiration of others and fail to establish a system to assess themselves," says Zhu Wenbo, a psychologist with Blue Bay Psychological Consulting Center in Chengdu．"People’s opinions always change, so this is not a reliable way to evaluate oneself．"

Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry’s trade association, CTIA, estimates（估计） more than 48 billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation’s emergency alert system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies.
"The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alert system by carriers –telecommunications companies is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alerts.
There would be three different types of messages, according to the rules.
The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (绑架) emergencies, or so-called Amber Alerts.
The service could be in place by 2010.
小题1:What is the purpose of the approved plan?
| A．To warn people of emergencies via messages. |
| B．To popularize the use of cell phones. |
| C．To estimate the monthly number of messages. |
| D．To promote the wireless industry. |
| A．CTIA | B．the Warning Alert and Response Network |
| C．FCC | D．federal regulators |
| A．the US federal government | B．mobile phone users |
| C．the carriers themselves | D．the law of the United States |
| A．Cell Phone Alerts Protecting Students | B．Cell Phone Alerts by Wireless Industry |
| C．Cell Phone Alerts of National Disasters | D．Cell Phone Alerts Coming Soon |
