    　　Overcoming shyness is not impossible．Let's discuss the steps to bring you out of shyness．

    　　Step 1

    　　Overcoming shyness is mainly a case of mind over matter．If you're afraid to do it, then do it again．The more you come to talk with people, the easier it will become．You may also find that it's not as difficult as you thought anyway．Just talk to people a little more every day．

    　　Step 2

    　　Step 3

    阅读下面短文，根据短文内容完成下列各题。

    What is the top hit single of 2006? It′s "Don′t Wanna Grow Up "!

       Taiwan girl band S.H.E took home the gold hit award at the 2006 Hong Kong TVB8 Top Chart Awards (金曲榜) last week, with "Don't Wanna Grow Up" from their eighth album "Once Upon A Time".

        It′s the first time S.H.E has won the award. The three members, Selina, He be and Ella were all very excited about it. They not only performed the song at the award ceremony, but also offered big hugs (拥抱) when giving awards to their artists.

    "Don′t Wanna Grow Up" is a song with light tunes (旋律) and easy lyrics.

    It′s music writer Zuo Arian used the tunes from Mozart's Symphony No.40 as the refrain (副歌). That gives the song a very classical feeling.

          The song had been quite popular among high school students since it came out. Xiao Xue, a Junior 3 student from Shanghai, said that she often hums the refrain part herself.

       "I like the lyrics, too," she said, "I often wish that I could go back to my childhood, when I had enough time to play and didn′t have to worry about all the exams."

    S.H.E said that the song also expresses their true feelings. Their rocking success in the past six years has led to the three young girls heavy workloads and forced then to grow up quickly. 〝When we. first, started singing, we were quite relaxed and we had our own musical dreams," said S.H.E. "Don′t Wanna Grow Up′reminds us of those happy times and of our original dreams."

    1. Where are the members of S.H.E from?

    2. Why does the song "Don't Wanna Grow Up" have a classical feeling?

    3. Xiao Xue prefers the refrain part to the lyrics, doesn′t she?

    4．将第四段划线句改写成含有定语从句的复合句。

    5．对文章最后一句做划线提问.
