However, a recent study has shown that under 20% of business owners would be willing to upgrade to the new version of Windows. The reason for this remains to be discussed and debated, and we will try to throw light on this research by providing you with some of the most common advantages and disadvantages of Windows 8,Generally speaking, there are a great number of plus sides related to upgrading from Windows 7 to Windows 8.Speed- this is the biggest advantage to mention.

Yes, there is no Start button in the lower left corner, and this might be a real puzzle of many Windows users. Also, many users have had a problem to get used to the new interface(界面）introduced by Windows 8.

Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate(迁徙）north.Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.According to Science Daily, a new study predicts that by the year 2100，many of todays familiar climates will be replaced by climates unknown in todays world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004，a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesnt matter what is causing it, but rather, what can be done about it. Whats more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.However, other planets are experiencing global warming as well as our own and some scientists there may be some connection between this. No one knows anything for sure at this point because there is simply, not enough data.1. What is the major function of Paragraph 1 ?A. To arouse the readers concern.B.

Animal and plant species may not be able to adapt enough and could disappear.B. It could lead to the spread of diseases.C. Current world climate zones could shift and completely disappear.D. Natural disasters are becoming more frequent and serious.4. What can be inferred from the passage?A. Animals and plants wont die out as long as climate changes slowly.B.
