LONDON—Terror struck in the heart of London on Thursday as explosions ripped through three subway trains and blasted(炸开)the roof off a crowded red double-decker bus. At least 37 people were killed and more than 700 wounded in the deadliest attack on the city since the blitz(闪电战)in World War II.

British Prime Minister Tony Blair blamed Islamic extremists and said the bombings were designed to coincide with the opening in Scotland of a G-8 summit of the world's most powerful leaders. Foreign Secretary Jack Straw said the bombings—which came the day after London won the bid to host the 2012 Olympics— have the “hallmarks(特点)of an al-Qaida-related attack”.

    Trapped passengers in the Underground railway threw themselves on the floor, some sobbing. As subway cars quickly filled with smoke, people used their umbrellas try to break the windows so that they could get air. Passengers emerged from the Underground covered with blood and soot(黑烟). On the street, in a light rain, buses ferried the wounded, and doctors used a hotel as a hospital.

     “I didn't hear anything, just a flash of light, people screaming, no thoughts of what it was. I just had to get out of the train,” said subway passenger Chris Randall, 28, who was hospitalized with cuts and burns to the face, the legs and hands.

     “It was chaos(混乱),” said Gary Lewis, 32, evacuated(撤离)from a subway train at King's Cross station. “The one haunting(萦绕)image was someone whose face was totally black( with soot) and pouring with blood.”

    Police said there had been no warning and that the blasts at three subway stations went off within 26 minutes, starting at 8:51 a.m. in an Underground train just outside the financial district. Authorities initially blames a power failure but realized it was a terror attack after the bus bombing near the British Museum at 9:47 a.m.—less than an hour after the first explosion.

    Arguments happen in every healthy relationship—we know it sounds contradictory, but it's true—but they can still have a negative impact if they aren't handled properly. {#blank#}1{#/blank#}

    Take a breath. We know that it can be hard to think clearly when you are angry, so we would first like to encourage you to try to take a second to collect your thoughts before engaging in a dialogue with your partner. {#blank#}2{#/blank#} If you are not careful you could potentially say what might damage your relationship.

    Take the situation as it is. Even though you are angry and it can be hard to be objective, try to see the situation for what it is. Do not escalate (不断恶化) the argument. {#blank#}3{#/blank#}Try to understand the purpose behind the action—if something happened accidentally, you should not treat as if it were done intentionally.

    {#blank#}4{#/blank#} If you have done something wrong, the best possible option for you is to admit it. Denying something only makes it more hurtful and often your partner will be able to forgive you much more quickly if you are honest.

    Set ground rules. After a fight you and your partner can have a heart-to-heart talk of what happened. {#blank#}5{#/blank#} At this point you can set some ground rules for future fights, like not cursing each other or calling each other's names, which might help reduce the intensity of your fights.

    Fighting with someone is never easy. And it's especially difficult when you are arguing with someone that you care about. Thinking carefully and controlling yourself during an argument can help you avoid saying something that could permanently hurt your relationship.

    Researchers P. Jason Rentfrow and Samuel Gosling gave 3,500 people a personality quiz. “We found that the musical styles people like are closely linked to their personalities,” Gosling says.

    RAP/HIP-HOP

    Known for their quick speech, some rappers can say more than 700 syllables（音节）a minute!

    If you like rap/hip-hop, you are energetic（精力充沛的）and have a way with words. You put a fresh spin on things, whether it's new moves on the dance floor or your hip style.

    CLASSICAL

    In the 18th century, classical musicians were like rock stars. Beethoven and Mozart, for example, played in crowded concert halls.

If you like classical, you are open to new ideas and like debating with friends. Creative and imaginative, you can easily spend many hours scrapbooking, writing or painting.

    COUNTRY

    Country music came from the folk songs of English, Scottish, and Irish settlers of the southeastern United States.

    If you like country, you express your opinions well, which makes you the ideal class president or team captain. Traditional and loyal, you enjoy spending time with your family.

    POP

    Pop music is designed to attract almost everyone, and it does. Each year, the industry brings in about 30 billion dollars!

    If you like pop, you are attractive to your friends. You can make big things happen, like planning for a huge party or inspiring your team to victory.

ROCK/ALTERNATIVE

    In the 1950s, rock music created a brand-new culture. Teenagers, for the first time, had an identity separate from adults and children.

    If you like rock/alternative, you are a risk-taker who never accepts no for an answer. You rise to any challenge, like doing very well in a big exam or landing the lead in the school play.

    If these personality profiles（人格剖析）don't match you, that's OK. These are just for fun.

    When mentioning China, what comes to mind? As a country with a history of more than 5000 years, China is rich in civilization and culture. What best represents China?

Confucius (551BC - 479 BC)

    Confucius was a teacher and philosopher from the Spring and Autumn Period of Chinese history. The philosophy of Confucius stresses individual morality including kindness, fairness, politeness, and sincerity. Confucius' principles have a broad basis in common Chinese tradition and belief.

Dragon

    A dragon is a legendary creature, typically with winding or crawling characters. The dragon symbol is frequently used on ancient Chinese emperor's items including chairs or costumes. It is considered a representation of power.

Peking Opera

    Peking Opera is considered the essence of China. As the larger form of Chinese opera, it has many “firsts” in Chinese dramas: the abundance of talents, the number of artists, opera groups and audience.

The Great Wall

    There is an old saying that goes, “He who has never been to the Great Wall is not a true man.” The Great Wall, one of the greatest wonders of the world, is a destination one must see when visiting China.

Traditional Chinese Medicine (TCM)

    Developed in China, TCM has a tradition dating back to more than 2,000 years, including various forms of herbal medicine, cupping, massage, exercise (Qigong), and dietary therapy.

    People love cellphones, which is why nine in ten Americans own one. But does heavy use of cellphones pose a risk of cancer? This question has caused controversy for many years. A new study in rats now augments those concerns. Its data linked long-term, intense exposure to radiation from cellphones with an increased risk of cancer in the heart or brain. The results have yet to be confirmed, the authors note.

    Indeed, although the rat study found a link between cellphone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet. He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles. Still, he calls the new study's findings “significant”.They could lead to studies researching how cellphone radiation might cause cancer, he says.

    Phone signals are relayed between cell towers and cellphones via radio waves. This radio frequency—or RF—radiation is a type known as non-ionizing (非电离的).Unlike X-rays, non-ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation, such as X-rays. But that does not mean radio waves might not cause harm.

    In very large doses (量) this radiation will heat the body and cause tissue damage. But it's not yet known what much lower RF levels might do, such as those from cellphone use. Five years ago, the World Health Organization's International Agency for Research on Cancer, or IARC, concluded that cellphone use “is possibly carcinogenic (致癌的)”.

    Its conclusion was based on what little research data was available at that time. But notice that IARC was not certain. It said only that phone use might “possibly” cause cancer. So scientists at the National Toxicology Program, or NTP, investigated further.

Rosie, a first-year university student in Beijing, entered a classroom for her oral English exam and slid her topic across the table to Joe, a foreign teacher. My Story, it read. "In middle school, my classmates laughed at me for having deaf-mute parents," she began softly. "From that moment on, I decided not to tell anybody. But today…"

It's widely considered taboo(忌讳) in Chinese to discuss the details of an unhappy family life with anyone other than very close friends. However, as Joe has noticed, many Chinese students appear surprisingly comfortable discussing emotional moments from their lives when they speak with foreign teachers in a language different from their own.

"Speaking English," one of his Chinese students told him, "I feel like another person." When speaking Chinese, he is kind of reserved; in English class, he is more open. English, to the Chinese speaker, may be like a mask, creating a buffer(缓冲物)between speaking the truth and the listener's reaction. Students focus on how to speak rather than what is being said. If there's a misunderstanding, English can take the blame.

Another reason why Chinese students are more comfortable sharing their secrets during English class may be the distinct approach to teaching used by their foreign teachers. "I always try to come to each student, make eye contact, have a 20-second conversation and see how they are doing," Joe said. Classes taught by Chinese teachers, in contrast, are more formal. Many students said they had never been asked their opinion in class.

Rosie's English vocabulary is now extensive, but she still can't find the words to describe her feelings towards the English language. "English makes me feel I am different," she said. "English is beautiful."
