It is said that four children died in fire yesterday.
The earth’s surface temperature has risen by about 1 degree Fahrenheit and sea level has risen 4-8 inches over the past century. Warming has occurred in both the northern and southern hemispheres (半球), and over the oceans. Confirmation of global warming is further proved by melting glaciers, decreased snow in the northern hemisphere and even warming below ground.
There is new and stronger evidence that most of the warming over the last 50 years is due to human activities. Human activities have altered 改变 the chemical composition of the atmosphere through the buildup 布局 of greenhouse gases. Problems may arise when the atmospheric concentration (浓度) of greenhouse gases increases. Scientists generally believe that the burning of fossil fuels and other man activities are the primary reasons for the increased concentration of carbon dioxide. Fossil fuels are burned to primary cars and trucks, heat homes and businesses, and power factories. Increased agriculture, deforestation, landfills, industrial production, and mining also contribute to a significant share of emissions.
Global warming poses real risks. Our health, agriculture, water resources, forests, wildlife and coastal areas are in danger to the rapid climate changes that global warming may bring. This is why we have to use our best judgment to determine what the most appropriate response should be. Individuals should recognize that collectively they can make a difference. It only takes little changes in lifestyle and behavior to make some big changes in greenhouse gas reduction Keep in mind that the changes are significant when the action is multiplied by the 6 billion people worldwide. Everyone’s contribution counts. so why not do your share?

The author attempts to start a conversation with her/his friend Adam ,but Adam was busy texting using his cellphone, which disappointed her/him. She/He thought people should not be under the control of technology. What happened to the author reminds me of some negative effects caused by cellphone on teenagers’ life. Some of my classmates bring their cellphones to the classroom, which distracts them from putting their heart into their studies. Others spend too much time playing with cellphones, which makes them ignore their friends and families.
It is certain that students can keep in touch with friends by cellphones. But we should bear in mind that spending too much time on it is harmful to us. There are times when it’s OK to text or make a telephone call, such as to remind or ask a friend about something. But I don’t think texting frequently is necessary when I’m with my friends, in class, at a family dinner or at the movies.
