A cold drink may be just the thing. But be carefu "I what you pour down your throat; something that looks
cool may not be good for your health.
There are plenty of so-called energy drinks on the market. Most of them have an attractive color and
cool name.
But after a careful check you may find that most energy drinks have high levels of caffeine. These drinks
are specially aimed at young people, students, busy people and sports players. Makers sometimes say their
drinks make you better at sports and can keep you awake. But be careful not to drink too much.
Caffeine raises your heartbeat. Because of this, the Intemational Olympic Committee has limited their use.
The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.
Research by Australian scientists has found that many teenagers are affected by caffeine. The results of
their study show that 27 percent of boys aged 8-12 take in more caffeine than their parents. There are hidden
health problems connected to energy drinks. Just one can of energy drink can make you nervous, have
difficulty sleeping and can even cause heart attacks.
"Teenagers should not be encouraged to have drinks with high level caffeine in them," a scientist from
the Australia Nutrition Foundation said.

off planes at a small airport near College Station. All of them were running away from Hurricane (飓风) Ike.
They had something else in common as well. Each passenger wore a bright yellow wristband (腕标), RFID,
developed by Rubio"s company. The wristband had a computer chip (芯片), which allowed the state"s
emergency response center (急救中心) to follow the person who wore it.
"The wristband really made a difference," says Rubio, adding that thousands of families who called the
state"s emergency response center during the hurricane were able to find loved ones. The wristbands also
made a lot of money for Rubio"s company.
That"s a goal Rubio could not have imagined even a few years ago, as a 36-year-old stay-at-home mum
with three kids under ten and a husband who traveled for work five days a week. "All I wanted was to have
my family back together," she says.
Rubio considered doing something different after the birth of her third child and returned to work. A friend
suggested the technology of RFID. It wasn"t new but was mainly used to find packages.
Rubio began imagining wider use of RFID, and in 2005 the wristband appeared at a business conference and
did a good job. In the wake of Hurricane Katrina, the company further used the technology, and later during
Ike about 27,000 people were successfully saved.
"I"m a mum with three kids or a woman in a technology field. I"ve succeeded and got confidence (信心)."
Rubio also achieved something else. She finally has the family life she always wanted.
B. be allowed to get on the planes
C. lead their way to a safe place
D. be found easily by other people
B. she liked the new technology
C. she needed a change in life
D. she was used to hard work
B. All right.
C. Not well.
D. Very badly.
B. Family life.
C. Creat success.
D. Social position.

| It took me three long and hard years to get a lovely little dog named Dion. My family and I met it at a dog show. We drove for four hours to its owner"s house where she showed us three little dogs, two males and one female. They were so lovely with their little legs, long bodies and heads that looked too big for their bodies. It took me a long time to decide which one I wanted,but I finally decided when the female came up to me and licked (舔) my face. My mother and I took Dion to a kindergarten (幼稚园) for little dogs. She was very shy and hid from people. But she was very friendly with the other dogs. If you want to get a dog, think about your time and the work you must do. I walk Dion four to six times a day. I feed her, spend time with her and watch her when she is out of her doghouse. Even if my favorite TV program is on, or a good part in a movie is coming up, I still have to take care of her. It is a lot of work to keep her clean. Sometimes when I brush her I end up with hair all over me. But I think it is all worth it. Dion also gives her love to me in return. She is always there to lick me and lie on me. I like playing with her. I think she can tell when I am happy, sad, angry or troubled. Dion is not only my dog, but she is also my friend. |

| Have you seen Avatar (《<阿凡达》)? It"s a popular movie this year. It is three-dimensional (3D), so you may have to wear a special pair of glasses to see it. The 3D glasses make the images (图像) from the movie look like they are coming straight at you. More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. Three-dimensional technology can make TV and movies more exciting. But people with eye problems may get headaches if they spend too much time watching 3D movies. Why? When we look at an object, each eye sees it at a different angle (角度). Our eyes send the two images to our brain, and the brain puts them together. That" show we see depth. Three-dimensional technology uses two film projectors (投影机). One projects a left eye image and the other projects a right eye image. 3D glasses allow us to see a different image in each eye. There are a lot of people walking around with very small eye problems, for example an eye muscle imbalance. Under normal situations, the brain can get used to their eyes so they can see things normally. But when they are watching a 3D movie, the images projected to their eyes can"t be put together by their brain. So the brain needs to work harder at "reading" the images. That makes it easier for these people to get dizzy or develop headaches. Dr John Hagan, an eye doctor in Kansas City, said some people who do not see depth normally cannot see in 3D at all. He said people whose eyes can" t focus on (聚焦) the same object at once will have trouble seeing 3D images. |

| A. our brain will get a different image from each eye B. our brain will put the different objects together C. our eyes will focus on the same object easily D. our eyes will see an object at the same angle |
| 2. What does the underlined words "normal situations" mean? |
| A. When people see things normally. B. When people have no eye problems. C. When people don"t have a headache. D. When people aren"t seeing a 3D movie. |
| 3. What does the writer want to tell us in this passage? |
| A. Seeing 3D movies can bring us eye problems. B. Not all the people can watch 3D images. C. The 3D glasses make the movie seem alive. D. The 3D movies will be very popular soon. |

| Today is the Earth Day. Our reporter Nick Ford interviewed several people in the street. This is what they told him: 9:24 Miss Mayfield, a young teacher I try to tell my students the importance of our relations with wild animals. I take them to zoos and forests, and I avoid using materials that come from wild animals, for example, ivory, which comes from elephants. I don"t wear things made of fur, and I even avoid buying leather shoes. Wool is okay, though-the sheep don"t get hurt! 10:03 Mr. Perdue, a businessman I don"t use my car for short journeys. I walk or go by bike. It"s good for my health, and it doesn"t pollute the air. 10:30 Tom Pitt, a 14-year-old student I only buy writing paper and notebooks made from recycled paper. And when I buy something made of wood, like a wooden table, I"ll make sure that the wood comes from a forest where they plant new trees. 11:01 Mr. White, an artist I"m an artist, and I enjoy recycled art. They are things made out of rubbishlike this model plane made from old containers. In fact, I hate throwing things away. I even keep my old woolen clothes and cotton handkerchiefs and use them for cleaning. 11:35 Ms Nelson, a policewoman I"m careful not to waste electricity. For example, I always turn the lights off when I leave a room. And I don"t have the TV on when I" m not watching it. 12:00 Mr. Parks, a doctor I take my empty bottles, jars, and anything else made of glass to the recycling center, every week. I try not to buy plastic bottles because you can"t recycle most kinds of plastic. |
