2)描述变化;
3)说明原因。
【正确答案】
Weibo

As is shown in the above table, among various social network services, the monthly effective browsing time ratio for microblogging rose from 1.2% in March to 10.0% in November at the same year of 2010, which grows above 6 times. However, for social networking site, the monthly effective browsing time proportion fell from 74.3% to 62.2% , and the community website increased from 23.1% to 26.2%.
Possible reasons account for the popularity of weibo. For one thing, due to the rapid spread of information and good interaction, weibo is increasingly popular among users. Thus the major portals and other Internet service providers all provide microblogging services. For another, as weibo services improve gradually and the influence of some "star microbloggers" (most of them are celebrities) grows, weibo is becoming an important way for people to establish and maintain relationships with the people that we meet on social media sites.
From the above reasons, we can predict there will be more and more people starting to use these services in the future.
