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 fresh 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 (通信) 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 (日冕物质抛射) occur in the Sun’s atmosphere, throwing out great quantities of electrically-charged (带电) matter. “A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometers 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 (太阳耀斑) and explosions as they occur.

Professor Richard Holdaway, 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 underlined part in paragraph one most probably refers to _______ during the 2012 Olympics.

A. the state of the Olympic torch being put out

B. the failure 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 deadly 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 decreases after coronal mass ejections.

3.

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

The baby is just one day old and has not yet left hospital. She is quiet but alert（警觉）. Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze（凝视）starts to lose its focus--until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
　　 Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise（同样地）when the researchers started with drumbeats and moved to spots.

1.The experiment described in Paragraph 1 is related to the baby’s　　　 .

A. sense of hearing　　 B. sense of sight

C. sense of touch　　 D. sense of smell

2.Babies are sensitive to the change in _______.

A. the size of cards　　 B. the colour of pictures

C. the shape of patterns　　 D. the number of objects

3.Why did the researchers test the babies with drumbeats?

A. To reduce the difficulty of the experiment.

B. To see how babies recognize sounds.

C. To carry their experiment further.

D. To keep the babes interest.

4.Where does this text probably come from?

A. Science fiction.　　 B. Children’s literature.

C. An advertisement.　　 D. A science report.
