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 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 Hold away, 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 advance 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.

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

2. What can be inferred about the solar activity described in the passage?

A. The most fatal matter from the corona falls onto Earth.

B. The solar storm peak occurs in the middle of each cycle.

C. It takes several seconds for the charged matter to reach Earth.

D. The number of sunspots declines after coronal mass ejections.

3. 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            D. improve the communications on Earth

4. Which of the following might be the best title of the passage?

A. Solar Storms: An Invisible Killer

B. Solar Storms: Earth Environment in Danger

C. Solar Storms: Threatening the Human Race

D. Solar Storms: Human Activities to Be Troubled

Time, a faithful company of our life, is a universal topic. People are always curious about what it is, how it travels and who it meets.
Stephen Hawking, one of the world’s smartest physicists, once said. “I’m fascinated by time.”
Many of us are, and the popularity of time travel novels, movies and TV series has proved that. After Palace and Startling by Each Step achieved astonishing ratings last year, Palace 2 aired on January 20, attracting time travel fans back to TV.
Woody Allen’s movie Midnight in Paris achieved great success. It was nominated for Best Picture, Directing, Original Screenplay and Art Direction for the 2012 Academy Awards.
Dream of heroism
Time travel TV series and movies connect both today and the past, thus offering room for imagination. Imagination creates a chance for the young to fulfill a dream that is hard to achieve in reality.
Chinese writer Xi Juan is a pioneer of time-travel stories in China. In 1993 she published a love story about a young woman time traveling to ancient times. The leading role’s modern personality and perception of love help her win the heart of a cool, handsome martial art master. Such a plot satisfies female fans’ love fantasy.
Starting from the late 1990s, novels about men traveling back to the past prevailed (盛行), with a Step into the Past as the most popular example. In these stories, the male leading roles accomplish great things with their modern skills and wisdom.
It is usually “a dream of heroism come true”, along with enviable romances.
Eye candy
“I’m hooked by the shows because they are characterized by dramatic and poetic love and have eye-pleasing actors,” Xia Xiaoyan, who works for a foreign-owned enterprise in Shanghai, explained her love for time travel TV series.
Her comment echoes a 2011 survey by Creat Marketing Research Co Ltd in China. When asked about what is so appealing about time travel TV series, 21 percent of respondents answered, “These attractive characters.”
A bigger reason behind the popularity of time travel stories, however, is the relaxation they offer, according to the survey.
Cai Yinong agrees. “Many people are facing tremendous pressure in their fast-paced lives, so this genre is more relaxing than other shows as it provides people with a terrific outlet to escape reality,” Cai told China Daily.
Cultural homesickness
“Which dynasty would you like to live in if you could travel to the past?” asked a survey launched by Shanghai University and Shanghai Social Sciences Association last December.
About 60 percent of the 2,543 respondents chose Tang Dynasty, while Qing Dynasty, and the Spring and Autumn and Warring States periods were the other top two destinations.
The survey results reflects people’s definition of the good days: prosperous economy and culture, steady society, fair and uncorrupted politics, and opening up to the outside world.
As for the movie Midnight in Paris, it features modernity versus cultural homesickness. The New York Times commented, “The past seems so much more vivid, more substantial, than the present. The good old days are so attractive because we were not around, however much we wish we were.”
