It is midnight on September 22,2012.The sky above Manhattan,New York is filled with a curtain of colorful light. New Yorkers are fascinated by the beautiful aurora(極光).However, their fascination is short-1ived.

 Within a few seconds,electric bulbs dim(變暗)and flicker(閃爍),then become unusually bright for a few seconds.Then all the lights second  go out.Within 90 seconds,the entire eastern half of the US is without power.

 Besides the US,Europe,Japan and China are also  hit by the same terrible event.It is a violent solar flare(太陽耀斑),150 million kilometers away on the surface of the sun.

 Science fiction? No.A report funded by NASA and issued by the US National Academy of Sciences in January this year says it could happen.

 A massive solar flare is most likely on a spring or autumn night in 2012,according to the report.

Solar flares are huge explosions on the surface of the sun.In a matter of just a few  minutes they heat material to many millions of degrees and release as much energy as a billion megatons(百萬噸)of TNT explosives.Solar flares release a stream of charged high-energy particles(粒子).They are called“solar winds”

 If one solar‘‘wind’’should hit the Earth's  magnetic shield(磁揚),the result could be terrible for humans.

But there’s no need to run  for cover from solar winds.  They do not harm 1ife on  Earth,they only affect the way we live,especially since  we depend so much on modern  technology.They can pump extra electricity into power line,  and pipelines,causing blackouts and fuel leaks(泄漏).  Solar winds are also known to affect mobile phone operations, and may disrupt wireless Internet services.

Moreover, solar winds can prevent normal satellite operations,and disrupt radio communications  and navigation systems such as the Global Positioning System.

 Auroras  are  powered  by  solar wind.This wind blows  past the Earth at about 400-700 km per second and creates storms in the Earth’s magnetic environment.In the polar regions these explode into southern or northern polar lights.

 The most serious solar storm that hit Earth in history happened in 1859. It caused the failure of telegraph(電報)systems in Europe and  North America.

 So, for humans,the sun is  a  double-edged sword. Without1 the sun, there would  be no 1ife  on  Earth. Without the sun,   Earth would be a frozen dark   ball floating in space.However,  on the other hand,the sun can  disorder our 1ives from time  to time.    

10.What is the main idea of the passage?

A.It introduces to readers the advantages and disadvantages of the sun.

B.It describes a science fiction set in Manhattan on 22 September 2012.    

C.It shows readers the way in which solar winds form inside the sun.

D.It explains what solar flares are and their effects on human life.

11.The first two paragraphs are written_________.

A.to show a beautiful scene in a true story

B.to describe the beautiful scenery of Manhattan

C.to describe the power problem around the world

D.to introduce the topic of this passage

12.What can we conclude from the passage?

A.Solar flares will do great harm to those who are using the Internet.

B.Solar flares cannot reach as far as the polar regions.

C.Solar flares are huge explosions that happen inside the sun.    

D.1f it weren’t’t for our reliance on technology, solar flares probably wouldn’t affect us.

13.Solar winds will likely affect us in the following ways EXCEPT that    

A.normal satellite operations will be stopped

B.the lights in the areas affected will go out at the same time

C.people on the streets will be struck to death

D.some navigation systems will be out of order

After our early morning wake-up, we are still a couple of

hours away from the overlooks.It is pitch black.I can feel the

heavy humid fog left behind my last night's rain. This is why

the tour memo listed "flashlight". Unfortunately; the majority

of our hiking party of nine must have missed the memo, so we

have only four flashlights between us.

    An hoar later,we are on the trail. It is dark, foggy, wet and the rocks are alippery.We alternate places between the flashlights "haves" and "have-nots". As we march, the only voices heard are from the "haves": "Step up, step down, watch out for the rock on your left."

    We reach Intipunku with only 15 minutes to spare. The view at sunrise is not what we were told in the travel brochures. Three feet in front of our faces is a white substance called "fog".

    As we walk towards the Machu Picchu ruins, my anticipation is mounting. When will the fog lift? Slowly, as if someone is cranking up a curtain, Huayna Picchu begins to appear,overlooking Machu Picchu. First there are fleeting glimpses, and then finally, there is, in its full splendor.

    When I envisioned going to Machu Picchu, I always thought of mysterious ruins and the famous postcard picture looking toward Huayna Picchu. But there is more to this man-made / natural wonder of the World. It is the adventure of getting there. I knew I wanted to experience the feel of the Inca culture and the energy of this sacred valley, I also knew I didn't want to take the train, but needed to hike. Depending on your starting point,the Inca Trail is 25 to 33miles of semi-arid desert, breathless mountain passes and stunning tropical cloud forest. Our hike took us four nights and 25 miles to finish.

    Our local guide MaurO keeps telling us "no worries, the hike is 90 percent mental and only 10 percent physical. "I am not convinced that the physical percentage is correct, but I definitely become more and more excited as we are now getting closer to Machu Picchu.By getting myself into good shape, running 20 miles and hiking a 500-foot-high hill five to seven times per week before I left for Peru, I was able to enjoy the beauty of the hike and not worry much about aching muscles and lungs.

About flashlights, which of the following statements is true?

    A. The local guide had asked them to take flashlights for the hike.

    B. They had taken enough flashlights for the hike.

    C. Before they got to Intipunku, they depended a lot on their flashlights.

    D. They used flashlights all the time.

Put the following events into the right order.

     a. They reached Intipunku,

     b. They read the travel brochures.

     c. They walked on the trail in the dark.

     d. They advanced to get closer to Maehu Picchu.

     e. They enjoyed the splendor of Huayna Picchu.

     A. ebade        B. bacde         C. abced         D. bcaed

What does the underlined word "anticipation" in Paragraph Four mean?

     A. expectation   B. excitement      C. disappointment  D. enthusiasm

What can NOT be inferred from the text?

     A. The writer made good preparation for the tour.

     B. The Inca Trail took them four nights.

     C. Machu Picchu is in the country of Peru.

     D. They reached Intipunku ahead of time.

According to the writer, what attracted him most in the tour?

     A. Mysterious ruins.               B. The famous post-card picture.

     C. The hiking.                     D. The Inca culture.
