Many scientists think that the Earth is getting warmer and warmer. If the change continues, the natural world and human society will face danger. Scientists believe human activity is responsible for the climate change. We produce too many greenhouse gases. They keep heat in the air and make the Earth warm.

    Many of the world's governments agree. And they want to solve the problem. So from 7 to 18 December, 2009，they held a conference in Copenhagen, Denmark to talk about global warming and climate change.

    Representatives(代表) from 192 countries and regions went to the meeting. Although they have not reached an agreement, the Copenhagen Accord(《哥本哈根协议》) was an important beginning to save the Earth. It was made by a small group of countries including China，the USA，India, Brazil and South Africa. Some other countries at the conference also showed support.

    What are the key points of the Copenhagen Accord? The accord limits global temperature increases to 2C by 2050. Scientists think it could help the world to avoid serious climate change.

    The accord also says that developed countries must promise to cut greenhouse gas emissions(排放) to the UN by 31 January, 2010. The accord asks developed countries to give money to help developing countries.

    Many countries and organizations are disappointed that the conference didn't reach a legal document(法律文书). And they think the accord is not clear enough about its goals.

African leaders are worried that the goal of a 2℃ global temperature increase isn't good enough, because it will mean a much higher increase in temperature across Africa. This could cause big problems like food and water shortages across the continent.

    Still, UN Secretary General believes the conference was an "improvement".

    "Finally we reached a deal," Ban said," the accord may not be everything everyone had hoped for, but this is an important beginning."

    Americans think much about time. From childhood they learn to {#blank#}1{#/blank#} time. They are taught to be on time to go to school, to work and to do everything. When they are having a good time, they time goes easily. When a person is dying, they say he is living on borrowed time.

    Time is money. Time is knowledge. Time is {#blank#}2{#/blank#}in America. A working American has to work hard for eight hours a day or forty hours a week. This is the working time. In his free time, he also works hard for more money. Even on Saturday and Sunday he also works hard as {#blank#}3{#/blank#}. In the street you can hardly see a man walking{#blank#}4{#/blank#}. They walk very fast. In fact, they are running.

    They love time because time can bring them money and lots of things.{#blank#}5{#/blank#}sometimes they also hate time, because they feel they have become servants of the clock.

Courage is often thought to be one of the important spirits everyone needs. Then what is courage? {#blank#}1{#/blank#}One isn't necessarily born with courage, but one is born with potential(潜力). Kids build courage as they are growing up. 

 Many people talk about connections between courage and fear. {#blank#}2{#/blank#}If there is no fear, there is no need for courage. That is to say, courage is the ability to do what makes you feel afraid. Courage doesn't only mean great actions such as saving one's life or taking a big risk. {#blank#}3{#/blank#}For example, we show courage when we raise our hand to answer a hard question during class or try a new sport. 

 Courage is in everyday choices we make. Can you be kind to the new kid in class? {#blank#}4{#/blank#}Or can you stand up for someone in need? Often, these things don't come with praise, but they need courage. 

{#blank#}5{#/blank#}When we become brave enough to face failure, we'll be more willing to try new things and try again after we fail. Courage doesn't always shout. Sometimes courage is the little voice at the end of the day that says, "I'll try again tomorrow."
