Having finished her homework,Ma Li wants some music for relaxation(娱乐).As usual,she starts her computer and goes to Baidu.Come to download music files.But this time she is surprised when an announcement about protecting songs'copyright bursts onto the screen.The age of free music and movie downloads may have come to an end as Web companies like Baidu are accused of pirating copyright.Lawsuits(诉讼)have been filed against four websites offering free downloads.In September 2005, a Beijing court ordered Baidu to pay recording company Shanghai Push compensation(赔偿)for their losses.Baidu was also told to block the links to the pirated music on the website.This caused a heated discussion on Internet file sharing.

“Baidu's defeat in the lawsuit shows it is not right to get copyrighted songs without paying.Downloaders may face lawsuits or fines,”said an official.

Like many teens,Huang Ruoru,an 18­year­old girl from Puning in Guangdong Province,doesn't think that getting music from websites is wrong.She always shares her favourite songs downloaded from Baidu with her friends.When told about the lawsuit,she began to feel a little guilty about obtaining others' work without paying.

However,other teenagers have different ideas.Wang Yafei,a Senior 2 girl from Jinan,Shandong Province pointed out that file sharing is a good way to promote pop singers.“If I download a song and really like it,I will buy the CD,”she said.“So what the recording companies really should concentrate on is improving their music,rather than pursuing(追赶,追击)file­sharers.”
