These dreams can be very big, such as winning the Nobel Prize, or they can be small. You may just want to become one of the ten best students in your class.Once you find a dream, what do you do with it? Do you ever try to make your dream real? Follow Your Heart by Australian writer Andrew Matthews tells us that making our dreams real is life’s biggest challenge.You may think you’re not very good at some school subjects, or that it is impossible for you to become a writer. These kinds of thoughts stop you from getting your dream, the book says.In fact, everyone can make his dream come true. The first thing you must do is to remember what your dream is.Don’t let it leave your heart. Keep telling yourself what you want. Do this step by step and your dream will come true faster because a big dream is, in fact, many small dreams.You must also never give up your dream.There will be difficulties on the road to your dreams. But the biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of watching TV will lead to better exam results, while saving five yuan instead of buying an ice cream means you can buy a new book.

This is good as you have the chance to learn more skills and find new interests.根据短文内容，选择正确答案，并将其字母代号填入答题卷相应空格内。（共5小题，每小题2分，满分10分）1.Follow Your Heart is .A. the first thing you must do to make your dream realB. the most important dream to have for teenagersC. the name of a famous Australian writerD. the name of a book by Andrew Matthews2.
