The 2012 London Olympics had enough problems to worry about. But one more has just been added -- a communications blackout caused by solar storms.
　　After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
　　Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
　　"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
　　At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物質(zhì)拋射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. "A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is the greatest during a solar maximum when there is the greatest number of sunspots.
　　Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
　　The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太陽耀斑) and explosions as they occur.
　　Professor Richard Harrison, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advanced warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.
小題1:The phrase "communications blackout" in paragraph 1 most probably refers to____________ during the 2012 Olympics.
A．the extinguishing of the Olympic torch
B．the collapse of broadcasting systems
C．the transportation breakdown in London
D．the destruction of weather satellites

A．the sun’s activities have little to do with the earth
B．the London Olympic broadcasting will be possibly influenced by the 2012 peak of sunspots
C．the 2012 Olympic Games are during the solar maximum of throwing out greatest number of sunspots
D．solar explosion will cause strong storms on the earth

小題4:According to the passage, NASA will launch a satellite to _________.
A．take images of the solar system
B．provide early warning of thunderstorms
C．keep track of solar activities

The London Eye is a giant 135---meter tall Ferris wheel situated on the banks of the River Thames in the British capital. Since 20 January 2011, it has been officially known as the EDF Energy London Eye following a three---year deal with the company. It is the tallest Ferris wheel in Europe, and the most popular paid tourist attraction in the United Kingdom, visited by over 3.5 million people every year. The London Eye is located at the western end of Jubilee Gardens, on the South Bank of the River Thames In the London Borough of Lambeth in England, between Westminster Bridge( which has longer history than the famous Severn Bridge to the west of London) and Hungerford Bridge. When erected in 1999, it was the tallest Ferris wheel in the world, until surpassed first by the 160 m Star of Nanchang in 2006, and the 165m Singapore Flyer in 2008. A breathtaking feat of design and engineering, passengers in the London Eye’s capsules can see up to 40 kilometers in all directions. The London Eye is the vision of David Marks and Julia Barfield, a husband and wife architect team. The wheel design was used as a metaphor for the end of the 20th century, and time turning into the new millennium(千禧年). Back in 2000, the London Eye was known as the Millennium wheel. In 2009, a 4D Film Experience was added as a free extra to enjoy before your ride on the Eye. Once you get high enough and start coming down the other side, you will see people reach for their cameras. Here’s where the good stuff is right at your fingertips(or seems so). Parliament and Big Ben are beneath you, as are so many other historical things . If you are interested in other attractions in London, you can refer to the homepage.

Inside the pleasingly fragrant cafe, So All May Eat(SAME) in downtown Denver ,the spirit ofgenerosityis instantly noticeable :donation box stands in place of a cash register. Customers here pay only what they can afford, no questions asked.A risky business plan, perhaps, but SAME Café has done one unchangeable thing in the Mile High City for six years: Open only at midday, the restaurant allows poor local customers who cannot pay to work as volunteers instead. They can act as waiters and waitresses, and dishwashers, or look after the buildings and equipment for the cafe.   
It’s based on trust, and it’s working all right”, says co-owner Brad Birky, who started the café in 2006.  Previously volunteering at soup kitchens, the Birkys were dissatisfied with the often unhealthy meals they served there. “We wanted to offer quality food in a restaurant where everyone felt comfortable, regardless of their circumstances,” Birky says. SAME’s special lunch menu changes
daily and most food materials are natural and grown by local farmers. The café now averages 65 to 70 customers (and eight volunteers) a day. And the spirit of generosity behind the project appears to be spreading. In early 2007,one volunteer who had cleared snow for his meals during t he long
winter said goodbye to the Birkys, He said he was going to New Orleans to help with the hurricane clearing up,” says Birky.
小題1:What can we learn about the soup kitchens the Birkys previously worked for?

Opened in 1971, the Magic Kingdom was the first theme park at Walt Disney World. All Disney World theme parks are open 365 days a year, although opening and closing times for each park are different from day to day. If  you are traveling without kids, try to visit it on a school day to avoid the largest crowds. If you need to visit it during a school vacation, try at least to avoid the week between Christmas and New Year’s Day and the Fourth of July.
If you are not staying at a Disney World hotel, avoid visiting the Magic Kingdom on its Extra Magic Hours days. The hotel guests get into the park early on those days, increasing the waiting time for visitors who arrive at the normal opening time.
Buy your Walt Disney World tickets online at Disney World’s website. There will be some advice on picking the right ticket. See the guide to Disney World tickets. You will also need to call in advance to make lunch or dinner reservations (預(yù)訂). Disney accepts reservations, through 1-407-WDW-DINE, up to 180 days in advance. Time does pass quickly, so you should call six months before your trip to get a lunch reservation in the castle. We suggest you should have your lunch at Cinderella’s Royal Table for your tour. If you can’t get the reservation, ask for the Liberty Tree Tavern instead.
Keep in mind that to reach the Magic Kingdom, you must park at Disney World’s Transportation and Ticket Center (TTC) parking lot, take a tram (有軌電車), and then take a boat across the Seven Seas Lagoon to the Magic Kingdom.

The necktie looks set to follow the top hat in being handed over to the fashion museum by office workers within the next 50 years, according to research.
Nearly three quarters (74%) think the tie will not survive within British firms beyond the next half a century with the popularity of the open-collared shirt. Its demise is being blamed on the boom in creative businesses, such as Facebook and Google, and online trading companies where formal dress codes tend to be avoided in favour of a more casual approach.
Once considered an important part of business dress, the tie has become a victim of the spread of "casual Fridays" into other weekdays, according to researchers.
The poll, by Deal Jungle. com, which helps small and medium enterprises, found more than half (51% ) thought the tie would die out in offices within the next 20 years and almost a quarter (22%) believed it would last less than 10 years.
A spokesman for the site, which has 20, 000 registered members, said: "Ties have been around seemingly forever but increasing numbers of office workers are telling them to get away."

"The success of businesses such as Facebook and Google, where even the CEO turns up wearing jeans and a hoodie, also seems to have had a corrosive (侵蝕性) effect on the idea of dressing formally for work."
"Many of our members keep their expenses to a minimum by working from home so they feel no need to dress up to go to work. We know that when they meet with clients, they still put on a business suit, but a tie is no longer seen as an essential part of the suited-and-booted look."
"Instead, many businessmen and increasing numbers of executives choose a suit and shirt with an open collar. The tie-less suit creates an impression of a more approachable deal maker, someone who is still business-minded, yet creative and technology-sensible, too. "
小題1:Why are ties expected to disappear in offices?
A．CEOs in creative businesses set a rule to forbid wearing ties.
B．The idea of casual weekdays is increasingly accepted.
C．Office workers are tired of wearing ties daily.
D．The tie-less look appears more modern.
小題2:According to the spokesman, how are their members dressed before clients?
A．Business suits and casual jeans.
B．Formal suits and a shirt with a tie.
C．Casual suits and buttoned-up shirt.
D．Business suits and an open-collared shirt.
小題3:What kind of image does the tie-less suit create?
A．Accessible in business.B．Professional in fashion.
C．Casual in working.D．Creative in dressing.
小題4:What does the underlined word "demise" mean in Para.2?

Honesty may well be the policy, but it often deserts us when no one is watching, psychologists report today. Experiments with an honesty box to collect payments for hot drinks show that people are better at paying up when under the gaze(注視) of a pair of eyes. The surprise was that the eyes were not real, but photographed.
Researchers at Newcastle University set up the experiment in secret. They attached a poster to a cupboard of mugs above an-honesty box alongside a kettle ,with tea, coffee and milk. Over 10 weeks, they alternated each week between images of eyes and pictures of flowers.
Dr. Bateson, a behavioral biologist and leader of the study, said that even though the eyes were not real they still seemed to make people behave more honestly. They effect may arise from behavioral characteristics that developed as early humans formed social groups that increased their chances of survival. Individuals had to co-operate for the good of the group, rather than act selfishly.
"If nobody is watching us it is in our interests to behave selfishly. But when we think we're being watched we should behave better, so people see us as co-operative and behave the same way towards us, "Dr. Bateson said.
"We thought we'd get a slight effect with eyes, but it was quite striking how much difference they made. Even at a subconscious(潛意識的) level, it seems people respond to eyes, and that might be because eyes send a strong biological signal we have evolved(進化) to respond to."
The finding, which researchers believe sheds light on our evolutionary past, could be turned to practical use. The psychologists say images of eyes could promote ticket sales on public transport and improve monitor systems to prevent antisocial behavior.
小題1:This passage is mainly about _______________.
A．the policy of honesty
B．a(chǎn)n honesty box to collect money
C．evolution on honesty
D．a(chǎn)n experiment on honesty
小題2:The reason for doing the experiment secretly is that the researchers _____________.
A．wanted to get a comparatively more exact result
B．had known they wanted to do something illegally
C．meant to get the co-operation of their colleagues
D．intended to sell the hot drinks at a higher price
小題3:People behave honestly under watchful gaze of eyes because _____________.
A．they want to leave a good impression
B．they fear to be laughed at by others
C．they've got the nature through evolution
D．they take the photo for a real pair of eyes

Our spiritual intelligence quotient（精神智商）,or SQ, helps us understand ourselves, and live fuller, happier lives.
Though we're all born with SQ, most of us don't even realize that we have it. Fortunately, you don't have to sign up for classes to learn how to improve your SQ. Here are some simple steps that can lead you to this new level of understanding.
Sit Quietly. The process of developing spiritual intelligence begins with solitude（獨處）and silence. To tune in to your spirit, you have to turn down the volume（強度）in your busy, noisy, complicated life and force yourself to do nothing at all. Start small by creating islands for silence in your day. In the car, instead of listening to the music, use the time to think. At work, shut the door to your office between meetings, take a few breaths and let them out very, very slowly. Enjoy the stillness in your home after the kids are finally in bed.
Step Outside. For many people, nature sets their spirit free. Go outside to watch a beautiful sunset. If you are walking with the dog, take the time to admire flowers in bloom; follow the flight of a bird and watch clouds float overhead.
Ask Questions of Yourself. Ask open-ended questions, such as "What am I Feeling? What are my choices? Where am I heading?"
But don't expect an answer to arrive through some supernatural forms of e-mail. “Rarely do I get an immediate answer to my question,” says Reverend Joan Carter, a Presbyterian minister in Sausalito, California. “But later that day I suddenly find myself thinking about a problem in a perspective（角度） I never considered before.”
Trust Your Spirit. While most of us rely on gut（本能的）feeling to realize danger, spiritual intelligence pushes us, not away from, but towards some action that will lead to a greater good.
小題1:The passage is mainly about______.
A．what your SQ is and in what way it can benefit our life
B．what your SQ is and in what way it can be improved
C．the relationship between your SQ and your life
D．a(chǎn)dvantages and disadvantages of SQ
小題2:The underlined phrase "to tune in to your spirit" in the third paragraph probably
means to_________
A．get your spirit relaxedB．keep up your spirit
C．keep seated quietlyD．change your spirit
小題3:From the passage, we can know that the most important thing to improve your SQ is______
A．a(chǎn) peaceful mindB．deep thought
C．spare time and hobbies D．good spirits
小題4:According to the passage, which of the following is True?
A．Not everyone has SQ.
B．You have to go to classes to learn how to improve your SQ.
C．SQ leads us to take wrong actions.
D．SQ can benefit our life.
