The first Earth Hour was held in 2007 in Sydney, Australia when 2.2 million individuals(个体) and more than two thousand businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had grown into a global event with more than 50 million people across 35 countries and territories(行政区)participating(参加). Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent(紧急) by the hour. In March 2009, millions of people took part in the third Earth Hour. Over 4000 cities in 88 countries and territories have promised their official support for the event. On Saturday 27 March, Earth Hour 2010 became the biggest Earth Hour. A record said 128 countries and territories joined the global display of climate action.
The event is organized by the World Wide Fund for Nature, also known as the WWF. The organizers say climate change is one of the greatest threats(威胁) facing wildlife and nature. They also say when it comes to save energy and money, big changes start with small steps like turning out the lights. Now people are all joining together in a global effort to show that it’s possible to work on global warming. Earth Hour has brought about some new changes to our lives. People join in activities such as candle-lit dinners and star-gazing parties as a response to the call for "going dark".

This year , Earth Hour is asking people to take the next step and go beyond one hour. So if you haven’t done so, next year, late half past eight to half past nine, let us turn off the lights for one hour for the environment! Earth Hour is a call to stand up, to take responsibility(责任) and to get involved(与……有关) in working towards a better future. Earth Hour is a message of hope and a message of action. Everyone can make a difference.

The water tap was leaking(漏水) again, and the noise was driving Cassie crazy. Cassie looked at her watch. It was nearly nine o’clock. She climbed out of bed and stood on a chair by the shelf. Her mother’s Mr. Fix-It Book was on the top shelf. Cassie stepped down quietly. She read the book quickly until she found the page she was looking for, and then began to read carefully.
Next, Cassie opened a box in the kitchen and picked out the tools she needed--- a hammer, a wrench, and several small things. It was so easy job for her to do the repair, and she tried several times. Finally, the water tap was in pieces. One by one, she carefully laid them out on the table. That way she would know how they went back. While this was going on, her cat walked over to watch what she was doing.
Cassie worked late into the night. At one point, she thought she was done. Oops! A small piece that she had forgotten still lay on the table. Slowly Cassie took the water tap apart(分开) one more time. This time she made sure everything was in place. She turned the water tap on and then off. One…two…three… She waited a full minute. There was no leak! Cassie smiled and put the tools back into the box. Then she went back into bed.
The next morning, Dad was in the kitchen when Cassie got up.
“Notice anything, Dad?” she asked.
He looked around and listened. “Hmm, something’s missing… I can’t find out what it is… Wait, it’s too quiet in here!”
“That’s right,” Cassie said. ‘Something is missing. I fixed the water tap. It doesn’t leak any more.”
“That’s my girl,” Dad said.Its a good thing you are really like your mother.

Suppose you are reading a book. Suppose you suddenly close your eyes, can you still see the book? "Of course not." you will say. But can you tell why? You would p__【小题1】 say, "When I close my eyes, my e__【小题2】___ cannot get out of my eyes to get to the book." Many others might give an explanation(解释) very much like the above . But this explanation is w__【小题3】___.
You cannot see any object if light from that object doesn’t get into your eyes. Some of the things you see give off light of their own.
The sun, the star, a lighted lamp are examples that can be seen by their own light. S__【小题4】__ things are luminous(发光的). Most of the things you see are not giving off light of their own. They are simply reflecting(反射) light that falls on them from the sun or some other luminous bodies. The moon, for example, doesn't give off any light of i__【小题5】_ own. It's non-luminous. You see it because sunlight falls on it and some of it reflects in your d__【小题6】__. So moonlight is only second-hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from w__【小题7】__ you are, so that there would be no light for the book to reflect, then you could not see the book e__【小题8】__ with your eyes wide open.
