Julie Astonis ,an Australian housewife in Brisbane is one such example, Even though autumn is approaching Australia’s Brisbane in April, one can still watch colorful blooming (盛开的)flowers in Julie’s little garden, as she tells that in her community, “Each of us has a beautiful yard, The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden.”
“Gardening is the most popular club in our community,”she says, “A lot of retired people don’t just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training , So you can see that flowers continue to bols-som in our gardens throughout the year.”
Talking about her people’s sense of care for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog’s waste, “In our community ,you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass,”says Julie with a smile,“Taking care of the dog’s waste can also help to develop children’s sense of responsibility!”
As to protecting water resources , the Australian government has made strict rules for families, Julie says, “We certainly would not use tap water to water the flowers!”She ways almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, connect the water tank with their toilets.

举一反三
The device connects to a person’s knee, As the person walks, the device captures energy each time the person slows down, To do this ,the device helps with the slowing sown movement of the leg, The movements of the walking person push parts of a small machine that produces electricity, Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute, Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device ,Developers say it could help people who work in areas without electricity to operate small computers, The deice could also be used in hospitals to operate heart pacemakers(起博器),It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy, But the researchers hope to make a lighter, less costly version.An improved version should be ready in one year.
The developers hope the device will one day help developing countries, Nearly twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania,He created a bag carried on a person’s back that also produces power from walking, The knee device does not produce as much electricity as the bag ,But the bag requires the walker to carry a load of twenty to thirty kilograms.

Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct.The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity(酸性), overfishing and pollution.
The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation.This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel.
"Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project."In these regions, we"ll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said."Their projects will last initially for two years.We provide them with a whole host of tools to carry out their projects including funding and intensive training." She added.
Coral reefs are the planet"s most diverse marine ecosystem(生态系统), known as the rainforests of the oceans.Despite taking up under 0.2% of the ocean floor, they provide food and shelter for almost a third of all sea life.If we lose the ecosystems, we lose not only the biodiversity (生物多样性), but we also lose the capability of people to obtain income and food from coral reefs.
Climatic instability, which leads to rising sea temperatures, causes corals to bleach.Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour.Bleached corals often die if the stress continues.Among the 10 species chosen to start the Edge project are the pearl bubble coral, a food source for the hawksbill(玳瑁)turtle, and the Mushroom coral, which supports at least 15 brightly colored fish.

D.A Research about Endangered Coral Reefs. |
“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.
Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”
小题1:What can we learn about Dr. Marcy from the passage?
A.He is fond of watching Jupiter. |
B.He is from a scientist family. |
C.He dislikes working with Paul Butler. |
D.He is interested in finding life in outer space. |
A.The planet is not as protective as Jupiter. |
B.The planet is close to star 55Cancri. |
C.The planet proves to be a gas planet. |
D.The planet is as large as Jupiter. |
A.1995 | B.1985 | C.2002 | D.1981 |
A.he has found the system similar to the solar system. |
B.he has discovered an Earth-like planet there. |
C.he has discovered a rocky planet there. |
D.he has found signs of life in the system |
A.they felt discouraged | B.they carried on with it |
C.they failed in their attempt | D.they made some progress |
Sometimes an animal has a plant partner. The relationship develops until the two partners cannot do without each other. This is so in the corals(珊瑚)of the sea. In their skins they have tiny plants which act as “dustman”, taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from light so that they cannot live normally, the corals will die.

While admitting that times are tough for families across the country, Obama reminded students that hard work now can mean big success later. “Nobody gets to write your destiny(命运)but you,” he said. “Your future is in your hands. Your life is what you make of it. And nothing—absolutely nothing—is beyond your reach."
Obama spoke about his own life, and lessons he learned from his mother, who had to remind him to stay focused on his studies. He told students the recipe (诀窍) for success: “Showing up to school on time. Paying attention in class. Doing your homework. Studying for exams. Staying out of trouble. ”
Obama encouraged students to embrace(欣然接受)what makes them different. “We shouldn"t be embarrassed by the things that make us different,” he said. “We should be proud of them.”
He also suggested taking advantage of all of the opportunities at your school, and always being open to trying new things. “Just because you’re not the best at something today doesn"t mean you can"t be tomorrow,” he said. “Even if you don"t think of yourself as a math person or as a science person—you can still excel in those subjects if you"re willing to make the effort. And you may find out you have talents you’d never dreamed of.”
小题1:What does Obama mainly want to tell the students in Paragraph 2?
A.Some families are experiencing a hard time. |
B.Different people have different destinies. |
C.They can create their own future. |
D.Those who don"t study hard will achieve nothing. |
