Unit2If you want to succeed, you must be in good condition. “Then self-confidence is half done.” Not only can self-confidence make you succeed, but also it has a great impact on your work. Besides, you must be in favour of yourself. You will be cast down when your parents object to you doing something you love. You must bring yourself back to life and encourage yourself from time to time. Don’t let your work be done in vain.
You should also try your best to do your work, it will pay off and you will be bound to prove to your parents that you are right . I think you must strike this thing into your heart.If so, You will owe your success to self-confidence. Because self-confidence has made you grow up and succeed.（from Yangliu）Step 7 短语句型串成篇 1Unit 2Millie wanted to be journalist when graduating the university. But her father thought that she would try in vain to do it. Millie was cast down by what his father objected to her being a journalist.
She said, “ I should owe my success to my father and my sister . Because the objection of my father struck strong decision into my heart. And my sister was all in favor of my decision. Besides that, she also encouraged me that if I could work hard, I would be bound to become a good journalist from time to time . Not only did her encouragements have a great impact on my work, but also they brought my spirit back to life, I had much confidence to keep on my work. My efforts paid off at last and my work is in good condition. If my father had approved of me being a journalist, I couldn’t have attained my goal. “The good seaman is known in bad weather.” Don’t be afraid of troubles, you must deal with them by yourself . Don’t give up and believe in yourself. (By Wangziyu)短语句型串成篇 2Group work(12minutes),
