Researchers and many scientists are concerned that the earth's climate and atmosphere are becoming warmer than they should be. What scientists do agree on is that the temperature will continue to increase if measures are not taken to reduce pollution and emission from cars and factories. It is widely agreed that oil and coal create greenhouse gases when they are burned to produce heat or power. These emissions include carbon dioxide, which is the cause of most of the global warming problem. The loss of the trees in many areas is making the problem worse, because trees and plants absorb carbon dioxide and release oxygen. The fewer trees that are left standing, the less carbon dioxide can be absorbed. Scientists predict that the sea level will rise, ice caps will melt, and some animals and plants will fail to survive because their habitat will disappear. There may be more deserts and less available farmland because of the dry ground, and there may be more storms and floods in many countries. Some countries, including the UK and the US, are taking steps to prevent the situation from becoming worse. There are programmes to educate citizens and students about the situation and recycling waste is becoming more common. New guidelines are being introduced to try to limit greenhouse gases from being produced by factories and businesses. Using more alternative energy sources is also a good way to prevent global warming. One thing that everyone can do is limit their use of energy every day, and you can do this no matter how old or young you are. Try to limit the unnecessary use of electricity and work to conserve energy every day. What is the best title for the text? A) How to Reduce Emissions B) What Global Warming Brings C) Take Action to Prevent Global Warming D) No Emissions, No Warming

In the early days of the Internet, the idea that it represented an entirely new and separate field distinct from the real world was seized upon by both supporters and critics of the new technology.Supporters liked the idea that the virtual world was a placeless datasphere, liberated from constraints and restrictions of the real world, and an opportunity for a fresh start.For instance, John Perry Barlow, an internet activist, issued the "Declaration of the Independence of Cyberspace" in February 1996.He thundered, "Governments of the industrial world, I come from cyberspace, the new home of mind.Cyberspace does not lie within your borders.We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth. Where Mr.Barlow found the separation between the real and virtual worlds exciting, however, critics regarded it as a cause for concern.They worried that people were spending too much time online, communicating with people they had never even met in person in chat rooms, virtual game worlds and, more recently, on social - networking sites such as MySpace and Facebook.A study carried out by the Stanford Institute for the Quantitative Study of Society in 2000, for example, found that heavy internet users spent less time talking to friends and family, and warned that the Internet could be "the ultimate isolating( ) technology". Both groups were wrong, of course.The Internet has not turned out to be a thing apart.Unpleasant aspects of the real world, such as taxes, crime and cheating are now characteristics of the virtual world, too.C'amers who make real money selling swords, gold and other things in virtual game worlds may now find that the tax man wants to know about it.Designers of virtual objects in Second Life, an online virtual world, are seeking to real -world lawsuits in order to protect their intellectual property. At the same time, however, some of the most exciting uses of the Internet rely on combining it with the real... The passage suggests that critics of the new technology _ . A) worried that friends would never meet in person B) believed that the Internet could isolate people online C) worried that people would be separated from the real world D) were concerned that people were addicted to social networks

(Question)
It was the day after Halloween when my grandmother was admitted to the hospital with the worst headache she'd ever had. While posing in our costumes the night before, we knew something was wrong, just not how wrong. Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas -- all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me. Then November 1, 1991 began her month-long stay in the hospital--she suffered from a rare infection called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess , and Grandma even made it into a local medical journal. Her doctor called her "the brain lady". Grandma celebrated her 85thbirthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother! When celebrating Halloween, the author's family _ . A) knew Grandma would appear in a local medical journal B) found that something was wrong with the costumes C) didn't realize that Grandma was feeling unwell D) didn't know how serious Grandma's illness was
