3a
Look at the title of the passage, discuss the following questions.
From Shy Girl to Pop Star
For this month’s Young World magazine, I interviewed 19-year-old Asian pop star Candy Wang, Candy told me that she used to be really shy and took up singing to deal with her shyness. As she got better, she dared to sing in front of her class, and then for the whole school.Now she's not shy anymore and loves singing in front of crowds.
I asked Candy how life was different after she became famous. She explained that there are many good things, like being able to travel and meet new people all the time.“ I didn’t use to be popular in school, but now I get tons of attention everywhere I go.” However, too much attention can also be a bad thing. “I always have to worry about how I appear to others, and I have to be very careful about what I say or do. And I don’t have much private time anymore. Hanging out with friends is almost impossible for me now because there are always guards around me.”
What does Candy have to say to all those young people who want to become famous “Well,” she begins slowly, “you have to be prepared to give up your normal life. You can never imagine how difficult the road to success is. Many times I thought about giving up, but I fought on. You really require a lot of talent and hard work to succeed. Only a very small number of people make it to the top.”

When he was a little boy, he seldom caused any problems, and his family spent a lot of time together. However, things began to change a few years ago. His parents moved to the city to look for jobs, and his grandparents came to take care of him. But he missed his parents so much and he often felt lonely and unhappy.

Li Wen’s unhappiness began to influence his schoolwork. He became less interested in studying. Sometimes he was absent from classes and failed his examinations. Finally, Li Wen’s parents made the decision to send him to a boarding school.

However, Li Wen was shy and not able to make friends quickly in school. He found life there difficult. One day he told his teacher that he wanted to leave the school. His teacher was worried about him and she called his parents. She advised them to talk with their son in person. So his parents took a 24-hour train and a 5-hour bus ride to get to Li Wen’s school.
They had a long talk. “It was exactly what I needed,” he said. “Now I understand that even though they are busy, they are always thinking of me. They take pride in everything good that I do.” 定语从句

After that, Li Wen ’s parents had much more communication with their son than they used to. Now Li Wen has really changed. He has become more outgoing and made some good friends in school. He has even joined the school basketball team and become active in many other activities. “I’m much happier now, and I work even harder than I used to. I know my parents love me and they’re always proud of me,” says Li Wen .“It’s very important for parents to be there for their children”.
