Have you ever thought, “I wish I could take a year off and just travel around the world”? Well, three lucky American teenagers were able to do just that. The teens—two males and one female--got an all-expenses paid, yearlong hike to five continents.

This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.

Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored (赞助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.

The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.

As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions. They realized that each of them can make a difference.

These teenagers went on the journey around the world _____.

A. to experience the most serous environmental problems on the earth

B. to bring the kindness of America to the other parts of the world

C. to go on sightseeing around the world

D. to call on more teenagers to join Earthwatch Institute

What’s true about their journey?  

A. They had to pay for their journey on their own expense.

B. They often had to move from one hotel to another.

C. They had to take great pains to collect environmental information.

D. They received a warm welcome every time they arrived at a new place.

It can be inferred that Earthwatch Institute could be _____.

A. an international university that takes in students from all over the world

B. a TV station that makes programmes on the beautiful scenery of the earth

C. a travel agency that organizes adventure trips specially for school children

D. an organization that brings science to life for people concerned about earth’s environment

What did they these teenagers learn from the journey?

A. It was high time that people protected the environment.

B. Long journey was not suitable for school children.

C. It should take the whole world to help the children.

D. Environmental problems can be solved if school children take part.

To win an Oscar is an achievement at any age. To do so at 22, as Jennifer Lawrence has, is just amazing. Recently, the American star won Best Actress at this year's Academy Awards for her role in the film The Silver Linings Playbook. According to Time magazine's Richard Corliss, Lawrence is that rare young actress who "lends a mature intelligence to any role".

Though Lawrence has found great success through her big screen work, Lawrence wasn't sure what she really liked doing before the age of 14. She thought she'd go to college and maybe find a career as a doctor or a travel agent.     

Lawrence's two brothers were star athletes and one of them was a straight-A student. Unlike them, she suffered through school, never quite finding where she belonged. However, during a trip to New York, Lawrence suddenly realized that she wanted to be an actress. When she was enjoying the beautiful city, a model seeker asked if he could take her picture, and the next day he called her in for an audition (试镜).      

"I read the script and it was the first time I had that feeling like I understand this," Lawrence said. "Within 20 minutes, in the cab ride from the hotel room, I decided I didn't want to be a model. In fact, I wanted to be an actress." Having appreciated this young lady's performance, the agency was so impressed with her reading that they signed her on the spot. But she insisted on finishing high school so she could give her full attention to her acting career.        

Lawrence burst onto the Hollywood scene last year with The Hunger Games, which established her as the highest-grossing (票房最高的) female action hero of all time. Rolling Stone called her “the most talented young actress in America".

A. confidence     B. ambition               C. independence  D. talent

4.What is the best title of the text? 

A. Choosing Right                                    B. Acting Wisely

Still want a laptop? That was so yesterday. Get ready for the next stage in the personal computer revolution: It's the ultrathin (超薄的), cheap netbook.
According to a New York Times report last week, personal computers are about to go through their biggest change since the rise of the laptop. By the end of the year, consumers are likely to see laptops the size of thin paperback books that can run all day on a single charge and are equipped with touch screens or slide-out keyboards. The netbook is a kind of portable computer with learner functions for online surfing and basic computing activities, for example, word processing. To cut the cost and weight, they usually have a low-powered processor, small screen, narrow keyboard, and no ODD.
Currently, some of the devices look more like a toy than a full-feature computer. That's because most of the netbooks sold today run on an Intel chip called Atom. This is a lower-power version of the company's standard laptop chip, so they have trouble running demanding software like games and photo-editing programs.
This year, a group of companies who make cheap, power-saving chips used in cell phones are applying that expert skill to PCs. That means they will break Atom's netbook dominance (统治地位) and reduce the size while letting it run complicated programs.
The big winner in the rise of netbooks will be the consumer. AT&T announced last week that customers in Atlanta, Georgia, US, could get a netbook for just $50 (342 yuan) if they signed up for an Internet service plan. This trend will soon spread to Asia, according to industry experts.
University campuses are a major target of Shanzhai netbooks—uncopyrighted (无版权的) domestic copies of foreign brands. These products are usually sold at less than 2,000 yuan. But industry insiders suggest students not use these nameless products because many of them don't provide good after-safes services.
49．The following are all advantages of netbooks EXCEPT that      .
A．people can easily edit photographs with them
B．they cost less than other personal computers
C．they are very thin and easy to carry
D．they save power

A．Because they are of poor quality.
B．Because they are not easy to operate.
C．Because they will soon be out of date.
D．Because they lack good after-sales services.
51．What can be inferred from the passage?
A．Laptops are becoming more and more popular.
B．University students seldom buy Shanzhai netbooks.
C．Shanzhai netbooks are sold better than those of famous foreign brands.
D．Atom's netbooks make up the largest part of the sales of portable computers at present.
52．What is the general idea of this passage?
A．Shanzhai netbooks are taking control of laptop market.
B．Netbooks have advantages over laptops in everything.
C．Netbooks are becoming the trend of personal computers.
D．Most of the netbooks sold today run on an Intel chip called Atom.
