The first Earth Hour was held in 2007 in Sydney, Australia when 2.2 million individuals(個體) 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（行政區(qū)）participating(參加). 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(緊急) 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(威脅) 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(責任) and to get involved(與……有關) in working towards a better future. Earth Hour is a message of hope and a message of action.

No Car Day was first started by 34 cities in France on September 22, 1998. It was started to protect the environment. By now, more than 1,000 cities around the world have had a No Car Day.
The first No Car Day in China was in Chengdu in 2001. Other cities including Taipei, Shanghai and Wuhan, also support the day.
In Beijing, more and more people are taking part in the activity. It asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars on June 5th (World Environment Day). The slogan(口號) for the day is, “ If we drive for one less day, we can have one more nice day.”
So far, more than 200,000 drivers have shown their support. “We can’t control the weather, but we can choose not to drive,” said Wu Zhonghua, a car club chairman. Beijing is trying to have 238 blue sky days this year. In the first quarter of 2007, Beijing only had 52 blue sky days. This was 11 days less than the number for the same period last year.

閱讀短文，根據(jù)其內(nèi)容回答問題。
Phys ed (physical education) is making a comeback, but with a difference. The new way is to teach skills that are useful beyond gym class, like lifting weights, balancing their diets and building physical endurance（耐力）.
Considering that 15% of American children 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-class model with fitness programs but also starting up phys ed programs because school boards（教育委員會）often “cut P.E. completely or decrease（減少）its teachers or the days it is offered,” says Alicia Moag-Stahlberg, the director of Action for Health Kids. The difference in phys ed programs is its short of a national standard.
The wisdom of the new idea has some scientific support. Researchers at the University of Wisconsin have showed how successful the fit-for-life model of gym class can be. They observed how 50 overweight children lost more weight when they cycled and skied cross-country than when they played sports. The researchers have also found that teaching group sports like football results in less overall（全體的）movement, partly because the students who are unwilling to do may sit on the bench.
Another problem with simply teaching group sports in gym class is that only a small part of students continue playing them after finishing their high school. The new method teaches skills that translate to adulthood, which means kids are given skills and experiences so they can lead a physically active life in their future.
小題1:Is the new Phys ed program different from the one before?
小題2:What does the new P.E. program teach the students?
小題3:According to the passage, what do some school boards do with P.E?
小題4:What are the problems with simply teaching group sports?
小題5:What’s the passage mainly about?

Expert(專家) say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger (手指) with his eyes still closed, begging(請求) for one more minute to sleep. Like thousands of students “early birds” in China, he has to get up before six every morning.
A report shows that without a good night’s sleep, students seem to be weaker (虛弱) than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.
Experts have ever said that the students should develop good study habits. So some clever students never study last, they are able to work well in class.
小題1:The 10-year-old boy begged for more minute to sleep because__________
