名校课堂系列答案Nations plan next steps to end global warming
On December 3，more than 10,000 scientists, environmental activists and government officials from 187 countries met in Bali, Indonesia, which is the largest global warming conference ever held.
One of the main goals of the two-week meeting is to develop a replacement for the international treaty called the Kyoto Protocol, which has been signed by 174, countries, calling for limits on the emission of greenhouse gases.
Under the Kyoto Protocol, nations were legally bound to reduce greenhouse gases, but since it was signed in 2005, they have continued to increase worldwide. Of the largest greenhouse gas emitters, only Russia and Japan have agreed to follow me rules. China and India－second and sixth on the list－are making efforts to make cuts.
The U.S signed the treaty in 1997 but has not yet agreed to follow the strict rules, which require that greenhouse gas release be reduced by 10% by 2012. U.S. officials are opposed to these mandatory（强制性的），or required, cuts in emissions. "We’re worrying that it would be too costly and would hurt the U.S. economy. But we're not here to be a roadblock," said Harlan L. Watson, a top U.S. climate official.
Even if greenhouse gases are reduced, scientists say it will take decades or longer to stop the global warming that is already underway. To help poor countries deal with rising temperatures and climate changes, the UN has developed the "Adaptation Fund" to help them improve farming techniques and water systems.
But so far, it has only raised $67 million.
"The money should come from the countries most responsible and most capable," said Kate Raworth, a senior research official from the Oxfam International aid group. She listed the U.S., European Union, Japan, Australia and Canada.

| D．the U.S thinks this conference of no importance |
| A．Japan | B．European Union | C．India | D．Canada |
| A．Because the greenhouse gases they emitted are not so harmful. |
| B．Because they fear that it would affect the U.S economy. |
| C．Because they shouldn’t be responsible for global warming. |
| D．Because they think these gases won’t cause global warming_____. |

What will you be doing when you are 26 years old? Studying at university or working for a living? Take a look at what Albert Einstein was doing at the age of 26.
100 years ago, Einstein was working in Switzerland. His hobby was physics. Without much money or help, he wrote five papers(论文) for a physics magazine. Three of these greatly changed the study of physics and our understanding of space, time, light and matter(物质). His most famous work is on the Theory of Relativity(相对论). Einstein was given the Nobel Prize for his discoveries. Although he also did many other things later, the years 1905 has been called Einstein’s “Year of Wonders”. It has been 100 years since then. Because of this, the UN has named 05 the World Year of Physics.
Today, over fifty years after Einstein’s death, a question is asked, “ Will there ever be another Einstein?” It may take a long time. After all, Einstein was born more than 200 years after Sir Isaac Newton, another great scientist. Besides, physics is a different field now, and education is different, too. Even if you can’t be the next great scientist, it is still helpful to remember some of the things that made Einstein great. He thought independently(独立地) and read widely. He left with us a formula(公式) for life: If A is a success in life, then A="X+Y+Z." X is work, Y is play, and Z is keeping your mouth shut.
1.The year 1905 is known as Einstein’s “Year of Wonders” because .

B．Einstein was 26 years old in 1905 |
|
C．Einstein made some very important discoveries in 1905 |
D．Einstein studied physics in 1905 |
2.Why hasn’t there been another scientist as great as Einstein?
|
A．Because the study of physics is not enough. |
|
B．Because it is hard to make important discoveries as Einstein did. |
|
C．Because people don’t work hard any more. |
|
D．Because physics is getting more and more difficult. |
3.The UN has named 05 the World Year of Physics because .
|
A．Einstein is 100 years old this year |
|
B．Einstein has been dead for more than 50 years |
|
C．there have been other great discoveries after Einstein’s death |
|
D．it is the 100th year since Einstein’s “Year of Wonders” |
4. What does Einstein’s formula for life mean?
|
A．Success means years of hard work. |
|
B．Success means all study and no play. |
|
C．Success means working hard, relaxing and not talking too much. |
|
D．Success is a secret that nobody knows. |
