Lets remember the day, 12th in May, in 2008. 2 Tremors1 were felt across China except the northeastern Jilin and Heilongjiang provinces and the northwestern Xinjiang Uygur Autonomous region. 3 And it also cut off electricity, telecommunications, transport and water supply.
We pay our respect to the countrymen2 who have been lost in the quake and pay tribute3 to the lives which were perished4 in darkness. The death toll in the quake had risen to 41,353 as of 8:00 p.m. on May 21, according to the earthquake relief headquarters. Those quake victims are our fathers, mothers, sons and daughters, brothers and sisters, and the same flesh and blood of the Chinese nation, and all the dear ones that cannot be torn away from the PRC. The anguish5 shall be taken jointly by 1.3 billion people across China and the distress shall be shared by the Chinese nation together.
4 We believe together with them, we can go through it, as everyone in our country is trying his or her best to do something for the victims. History shall prove that the earthquake can destroy some things but it is bound to recast them in other forms.
5 May the national mourning coheres the staunch belief to press ahead with the relief effort and the rebuilding of homes and inspire the countrymen and console those who have gone in the quake with our unyielding fighting will and concrete actions.
“Any difficulties cannot beat the heroic Chinese people.”

Every year there are changes in climate in different parts of the world. Some of these changes are due to natural causes.However, some climate changes are caused by air pollution and these changes may increase.
If the pollution affects the level of carbon dioxide in the atmosphere, the results are likely to be serious. Carbon dioxide has only a small part of the atmosphere. But it has an important function1 in keeping the balance between radiation from the sun entering the atmosphere and radiation leaving the earth. Some of the radiation is absorbed by the earth and some is radiated back into the atmosphere. The carbon dioxide in the atmosphere prevents some of the radiation from leaving the atmosphere. Thus the heat remains in the atmosphere and carbon dioxide helps to prevent the temperature of the earth from falling.
If the proportion2 of carbon dioxide in the atmosphere is increased as a result of air pollution the temperature of the atmosphere may rise. This might cause the ice in the North and the South to melt3. If this happened, the sea level could rise and parts of the earth would be flooded. This happening is not quite likely but the possibility exists.
There is also a fairly strong possibility that the dust level in the atmosphere will rise as . This dust pollution will reflect4 sunlight back into space. If this happens less sunlight will reach the earth and the temperature will fall.
Another danger comes from the destruction of the earths vegetation（植被）
such as the forests of Brazil, which are being cleared away for farmland and cities. Trees use carbon dioxide and their destruction may upset the balance of carbon dioxide in the atmosphere.
