Passage 1 Let's learn some of the green opportunities in an ordinary day. You get up in the morning, shower, and get dressed. Take shorter showers to save water. "Put a timer in your shower and see how quickly you can shower," suggests Byron Emmons. He's a student environmental leader at Northland College in Ashland, Wis. Or, he adds, pick a five-minute song (or shorter!) and see whether you can finish your shower before it ends. Try natural soaps with fewer chemicals and less packaging. Bars of soap use less packaging than liquid soaps, for example. Be aware that some body care products contain chemicals that can be harmful to the environment. Wear used clothes. Check out hip used clothing shops or Goodwill, suggests Kelly Simpson, an environmental educator in Oregon. "It's guilt-free, fun, and you can buy a lot more!" You go to school. Get there green. Walk or bike if you can. "It's good for your body and good for the planet," says Simpson. Otherwise, take a bus or carpool. Think twice about school supplies. Can you reuse notebooks or folders from last year? Teens Turning Green member Hannah Gross suggests getting a nice refillable pen and pencil set — goodbye, disposables. Green your school. "If you can turn off a couple of computers for even an hour, do it," says Emmons. "If you can turn off the lights in the restroom, do it. If you can convince your administration to turn off the lights in sunny hallways or classrooms, do it." You sit down for a meal. Eat less meat. It's a simple move that can have a big impact. All those animals need a lot of resources, such as grain and water, just to become our food. "For every pound of beef that you replace with veggies and tofu, you save hundreds of gallons of water," says Emily Packer, copresident of Teens Turning Green. Eat local. "If your food doesn't have to travel to get to you, you not only cut down on carbon emissions [from trucks], you also get fresher food!" Emily notes. If your area has a farmer's market, check it out. When buying an apple for a snack, consider choosing the apple that traveled the shortest distance to reach you. 1. What does "green" mean in the title "A Day in a Greener Life"? _______( )A. covered with grass or other plantsB. environmentally friendlyC. having little experienceD. full of energy

It challenges the belief that short-sightedness is caused by computer use, watching TV or reading in weak light. The Australian government researchers believe that the sunlight is good for people's eyes. They compared the vision and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the Singaporean children were short-sighted — this rate was ten times higher than Australian children. Both groups spend a similar amount of time reading, watching television and playing computer games. However, the Singaporean children spent an average of only half an hour a day outdoors — 90 minutes less than the Australian children. Professor Ian Morgan, from the Australian Research Council's Vision Centre, said, "Humans are naturally long-sighted,but when people begin to go to school and spend little or no time outdoors, the number of short-sighted people gets larger." We're also seeing more and more short-sighted children in cities all around the world and the main reason may be that city children spend less time outdoors. Daylight can be hundreds of times brighter than indoor light. But why does playing outside prevent us from becoming short-sighted? Scientists believe that natural light has a special chemical which stops the eyeball from growing out of shape and prevents people from becomingshort-sighted. So be outdoors. It doesn't matter if that time is spent having a picnic or having sports

题目10单选题
The underlined word in Paragraph 1 probably means "______".( )A. TirednessB. VisionC. Eye problemD. NearsightednessPassage 3 All resorts look very much alike whether they are in Bali or Negril. This is because many are owned by a select group of corporations who have bought up land with help from politicians in order to set up, say, a Club Med on some previously untouched beach. What is the point of spending all that time and effort to pay for a man-made illusion? Doesn't the idea of traveling to experience a new land, culture and environment sound better? There is much more to be gained by taking the back roads, supporting local establishments, veering from the mainstream, and looking behind the façade of the resorts. Traveling in a way that makes you feel integrated into your new surroundings opens the door to greater cultural awareness. In other words, it's important to see and experience a world outside of our own, to learn that it's not like at home everywhere, and to understand the value of other cultures. America is such an expansive country, with long distances between most state lines, let alone national borders, that many people never travel abroad. In comparison, Europe is far more diverse when it comes to the number of different countries in an area that is smaller than the U.S. Most Europeans speak more than two languages and have traveled to their neighboring countries. While regional and cultural differences exist, Europeans seem to have a much stronger sense of community across borders. The forces behind commercialized tourism have created the misconception that traveling has to be expensive. But that depends on a person's choice of travel style. There is a whole world apart from the resort towns and guided tourism that caters to middle- or upper-class people. Once you experience this real world, you'll never go back to the "package deals." Why go somewhere to be amongst people that are just like you? There is nothing new to be gained there. I encourage all those who have the inkling to travel and see the real world to just go out and do it
