Heading overseas on a business trip or just for pleasure any time soon？If so，have you thought about what you are going to do about communication？You may need to arrange cab service or get directions to an attraction，not to mention you want to stay in touch with the folks back home.
Hope you aren’t counting_on your personal cell phone.Industry experts estimate that most American cell phones won’t work overseas due to compatibility (兼容性) issues.And even if yours did work，the roaming (漫游) charges would be too high.
So what are your choices？You could rent a phone with a local number in the country you’re traveling to，but that wouldn’t do you much good if you’re constantly on the go.A more cost?effective way would be to rent a satellite phone from a company like Global Cellular Rental.
The process is amazingly fast and simple.All you have to do is to log onto the company’s website，www.globalcellularrental.com，and place an order.The site will show you the countries you will be traveling to and ask you how long you will need the phone.The company then ships a cell phone directly to you anywhere in the world.The phone arrives with complete instructions.
The traveler also learns his overseas phone number well in advance，enabling him to inform all vital contacts of the number before he ever steps on a plane.
Roaming rates are usually 80 percent less than those charged by American service providers.Calls back to the US can be discounted 40 percent or more.The rentals cost is just $5 per day，and discount packages are available for long?term rentals of two months or more.
This cell phone solution is becoming so popular that Global Cellular Rental actually has relationships with hotel chains around the world to keep phones in stock for hotel guests.And for those whose journey really takes them off the beaten track，the company can also rent satellite phones to them.These phones work anywhere in the world as long as you are outside.

解析 词义猜测题。由文章第二段第二、三句可知，通信专家说美国手机因为兼容问题到了国外可能不能使用，即便能使用，漫游费也会很高。由此可推出第一句的大致意思为“希望你不要依靠你的个人手机”，故B项“依靠，依赖”符合文意。
2.2】 C
解析 细节理解题。由文章倒数第二段可知，打回美国时，该公司的收费比其他的运营商收费要低，所以得知其为一家美国公司。该公司有一些连锁饭店，在饭店里也可租到手机，故A项错误；文中并未说明优惠资费包需要提前申请，故B项错误；对于一些去偏远地区的游客来说，也能得到这种服务，故D项错误。

名校课堂系列答案In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet（彗星）. When the fragment（碎片）landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the Earth’s atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the Earth, but the north won’t escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs（恐龙）were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn’t survive in the cold climate that followed and they became extinct. Will we meet the same end?
【小题1】 Which of the following is NOT TRUE according to the author’s description of the disaster in 2094?
The whole mankind becomes extinct.
All the coastal cities in African are destroyed.
The whole world becomes extremely cold.
The visit of the comet results in wars.
【小题2】Why does the author mention dinosaurs at the end of the passage?
| A．Because they could only live in the warm climate. |
| B．Because they once dominated the Earth. |
| C．Because dinosaurs and humans never live in the same age. |
| D．Because their extinction indicates future disasters |
| A．give an accurate description of the possible disaster in the future |
| B．warn of a possible disaster in the future |
| C．tell the historical development of the Earth |
| D．prove that humans will sooner or later be destroyed |
| A．horror story | B．news report |
| C．article of popular science | D．research paper |
As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets sage. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.
Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attracted meteor shower(流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn’t be able to see the meteor shower as well, and I would surely be run over by a car.
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you’ve ever taken a flight at night, the view is beautiful, but you must remember that all the light you see is wasted electricity. The crew of the space shuttles see an even bigger picture of ho
w extensive the wasted electricity is worldwide.
Additionally, electricity needs to be generated, and the generation of electricity creates pollution by giving off greenhouse gases. This affects the air we breathe and our quality of life.
Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny sea turtle hatchlings become lost and follow lights on the shore instead of heading towards the sea.
Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.
【小题1】The author tells the story in the second paragraph mainly to _________.
| A．remember the past beauty of the town. |
| B．stress the advantages of less pollution |
| C．show the great changes of the town |
D．prove the bad effects of li ght pollution |
| A．to try to reduce unnecessary light. |
| B．not to ignore the beauty around. |
| C．to set proper light for animals |
| D．not to destroy the animal’s living conditions. |
| A．Light pollution is difficult to deal with. |
| B．Light pollution is a threat to some animals. |
| C．Light pollution has nothing to do with global warming |
| D．Astronauts can’t see clearly in space due to light pollution. |
agraph?| A．The author’s contribution to light pollution |
| B．Other sources of light pollution |
| C．Ways of reducing light pollution |
| D．More bad effects of light pollution |
The drug store was closing for the night and Alfred Higgins was about to go home when his new boss approached him.
“Empty your pockets please, Alfred,” Sam Carr demanded in a firm voice.
Alfred pretended to be shocked but he knew he’d been caught. From his coat he withdrew a make-up kit, a lipstick and two tubes of toothpaste.
“I’m disappointed in you, Alfred!” said the little gray-haired man.
“Sorry, sir. Please forgive me. It’s the first time I’ve ever done such a thing,” Alfred lied, hoping to gain the old man’s sympathy.
Mr Carr’s brow furrowed as he reached for the phone, “Do you take me for a fool? Let’s see what the police have to say. But first I’ll call your mother and let her know her son is heading to jail.”
“Do whatever you want,” Alfred shot back, trying to sound big. But deep down he felt like a child. He imagined his mother rushing in, eyes burning with anger, maybe in tears. Yet he wanted her to come quickly before Mr. Carr called the police.
Mr. Carr was surprised when Mrs Higgins finally arrived. She was very calm, quiet and friendly. “Is Alfred in trouble?” she asked.
“He’s been stealing from the store,” the old man coolly replied.
Mrs. Higgins put out her hand and touched Mr. Carr’s arm with great gentleness as if she knew just how he felt. She spoke as if she did not want to cause him any more trouble. “What do you want to do, Mr. Carr?”
The woman’s calm and gentle manner disarmed the once-angry store-owner. “I was going to get a cop. But I don’t want to be cruel. Tell your son not to come back here again, and I’ll let it go.” Then he warmly shook Mrs. Higgins’s hand.
Mrs. Higgins thanked the old man for his kindness, then mother and son left. They walked along the street in silence. When they arrived home his mother simply said, “Go to bed, you fool.”
In his bedroom, Alfred heard his mother in the kitchen. He felt no shame, only pride in his mother’s actions. “She was smooth!” he thought. He went to the kitchen to tell her how great she was, but was shocked by what he saw.
His mother’s face looked frightened, broken. Not the cool, bright face he saw earlier. Her lips moved nervously. She looked very old. There were tears in her eyes.
This picture of his mother made him want to cry. He felt his youth ending. He saw all the troubles he brought her and the deep lines of worry in her grey face. It seemed to him that this was the first time he had ever really seen his mother.
