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.
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 |

Rae Armantrout, who has been a poetry professor at the University of California San Diego(UCSD) for two decades, has won the 2010 Pulitzer Prize in the poetry category for her most recent book, “Versed”.
“I’m delighted and amazed at how much media recognition that the Pulitzer brings, as compared to even the National Book Critics Award, which I was also surprised and delighted to win,” said Armantrout.
“For a long time, my writing has been just below the media radar, and to have this kind of attention, suddenly, with my 10th book, is really surprising.”
Armantrout, a native Californian, received her bachelor’s degree at UC Berkeley, where she studied with noted poet Denise Levertov, and her master’s in creative writing from San Francisco State University. She is a founding member of Language Poets, a group in American poetry that analyzes the way language is used and raises questions to make the reader think .
In March, she won the National Book Critics Circle Award for “Versed.”
“This book has gotten more attention,” Armantrout said, “but I don’t feel as if it’s better.”
The first half of “Versed” focuses on the dark forces taking hold of the United States as it fought the war against Iraq. The second half looks at the dark forces casting a shadow over her own life after Armantrout was diagnosed with cancer in 2006.
Armantrout was shocked to learn she had won the Pulitzer but many of her colleagues were not. “Rae Armantrout is a unique voice in American poetry,” said Seth Lerer, head of Arts and Humanities at UCSD.
“Versed”, published by the Wesleyan University Press, did appear in a larger printing than her earlier works, which is about 2,700 copies. The new edition is scheduled to appear in May. According to Rae Armantrout, ____________.
| A．her 10th book is much better |

What can we learn about “Versed”?
| A．It consists of three parts. |
| B．It is mainly about the American army. |
| C．It is a book published two decades ago. |
| D．It partly concerns the poet’s own life. |

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place. The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard. Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example. But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But is also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.What does the underlined phrase “over-consumption” refer to?
| A．Using too much packaging. |
| B．Recycling too many wastes. |
| C．Making more products than necessary. |
| D．Having more material than is needed. |
The author uses figures in Paragraph 2 to show _______.
| A．the tendency of cutting household waste |
| B．the increase of packaging recycling |
| C．the rapid growth of super markets |
| D．the fact of packaging overuse |
According to the text, recycling ______.
| A．helps control the greenhouse effect |
| B．means burning packaging for energy |
| C．is the solution to gas shortage |
| D．leads to a waste of land |
What can be inferred from Paragraph 4?
| A．Unpackaged products are of bad quality. |
| B．Supermarkets care more about packaging. |
| C．It is improper to judge quality by packaging. |
| D．Other products are better packaged than food. |
What can we learn from the last paragraph?
| A．Fighting wastefulness is difficult. |
| B．Needless material is mostly recycled. |
| C．People like collecting recyclable waste. |
| D．The author is proud of their consumer culture. |
Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with insulin(胰岛素) three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance. After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar , and created diabeticrockstar.com, a free online community for diabetics and their loved ones—a place where over 1,100 people share personal stories, information, and resources.
Jason Swencki‟s son, Kody, was diagnosed with type diabetes at six. Father and son visit the online children's forums(论坛) together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone." Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.
These days, Thomas's main focus is his charity慈善机构, Fight It, which provides medicines and supplies to people—225 to date—who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000—in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean.
Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar one of Rockstar's original members. "But Christopher is the only person I know saying people need help now." Which of the following is true of Christopher Thomas?
| A．He needs to go to the doctor every day. |

I have a friend who lives by a three-word philosophy: Seize the moment. Just possibly, she may be the wisest woman on this planet. Too many people put off something that brings them joy just because they haven't thought about it, don't have it on their schedule, didn't know it was coming or are too strict to depart from their routine.
I can't count the times I called my sister and said,“How about going to lunch in half an hour?” She would gasp and stammer(结结巴巴地说), “I can't. I have clothes on the line. My hair is dirty. I wish I had known yesterday. I had a late breakfast. It looks like rain.”And my personal favorite response:“It's just Monday.”She died a few years ago. We never did have lunch together. From then on, I've tried to be a little more flexible.
Life has a way of going faster as we get older. The days get shorter, and the list of promises made to ourselves gets longer. One morning, we awaken, and all have to show for our lives is repetition of “I'm going to”,“I plan on” and “Someday, when things are settled down a bit.”
When anyone calls my“seize the moment” friend, she is open to adventure and available for trips. She keeps an open mind on new mind on new ideas. Her enthusiasm for life is contagious. You talk with her for five minutes, and you're ready to trade your bad feet for a pair of Rollerblades and skip an elevator for a bungee cord.
My lips have not touched ice cream in 10 years. I love ice cream. The other day, I stopped the car and bought a triple-decker. If my car had hit an iceberg on the way home, I would have died happy.
Now go on and have a nice day. Do something you WANT to, not something on your SHOULD DO list.The example of the writer's sister serves as__________.

| C．To advise people to keep their promise. |
| D．To convince readers to be flexible on their schedule for practical joy. |
Every spring scores of people flock to the Buzzard Festival at Hinckley, Ohio. They come to watch for buzzards. Most would be glad just to take a look at a buzzard. If they do see one of these" flying garbage cans", it will probably be circling high in the sky. From there it can watch the ground for signs of the waste and the dead animals on which it feeds.
The buzzard is the ugliest bird in the United States. In fact, it may well be the ugliest bird in the world. It has a small, bare, pink head. Its thick body is covered with dark, rough feathers.
In spite of its looks, the buzzard is important to the people of Hinckley. It is their first sign of spring. After a winter in the south, buzzards return to their homes in the north. In the Hinckley area, they always return on March 15. No one knows why. But they have come back to Hinckley Ridge on that day, sure as clocks work, for at least forty years.
The excitement starts in February. By the middle of March it has reached a high peak. Bets are placed. Prizes go to the person who sees the first buzzard. Radio stations and newspapers tell of the coming festival. And on the weekend after March 15 the people of Hinckley hold their Buzzard Festival.
The people come and look around. They chat. They eat their fill of pancakes and sausages. Then they drive past Buzzard's Roost on Hinckley Ridge.
A lot of them stop near the road at the stand set up to give information to visitors. There they can hear, from a recording, the main facts about the buzzard. They can see a stuffed buzzard. They can look at some pictures taken of buzzards in other years. With good luck and a strong pair of field glasses, they may sight one or two live buzzards high in the sky.
Buzzards may be ugly. They may be "flying garbage cans". But in Hinckley they are just as welcome as the swallows in Capistrano, California. It would be a sad spring indeed if the buzzards ever failed to come back to Hinckley Ridge. A good title for this story would be __________.
| A．The Hinckley Buzzard Festival |
| B．Buzzard, the Ugliest Bird |
| C．Why the Buzzard Has a Pink Head |
| D．The Return of“The Garbage Can" |
The buzzard is called the "flying garbage can" because it __________.
| A．is ugly | B．eats waste and dead animals |
| C．looks like a garbage can | D．collect rubbish on the ground |

| A．they spend the winter in the south |
| B．they come very close to the town |
| C．they return on the same day each year |
| D．both buzzards and swallows return to Capistrano on March 15 |
