You may just want to become one of the ten best students in your class. If you find a dream, what do you do with it? Do you ever try to make your dream come true? Follow Your Heart by Australian writer Andrew Matthews tells us that making our dreams come true is life’s biggest challenge (挑战). “You may think you’re not very good at some school subjects, or that it is impossible (不可能) for you to become a star. You won’t make your dream come true with these ideas,” the book says. In fact, everyone can make his dream come true. The first important thing you must do is to remember what your dream is. Don’t let it leave your heart (心). Keep telling yourself what you want. Do this step by step (一步步地) and your dream will come true faster. A big dream is, in fact, many small dreams. Never give up (放弃) your dream. There will be difficulties on the road. But the biggest problem comes from yourself. You need to decide what is the most important. Studying instead of (代替) watching TV will bring you better exam points. Saving five yuan instead of buying an ice cream means you can buy a new book. When you get closer to your dream, it may change a little. Then you will be able to learn more skills and find new interests. 57．Follow Your Heart is ________. A. the first thing you must do to make your dream come true B. the most important dream to have for students C. the name of a book by Andrew Matthews D. the name of a famous Australian writer 58．If you want to make your dream come true, you should ________.

A. Watch TV to get better exam points. B. Do what you should do step by step. C. Always remember what your dream is. D. Read more books, learn more skills and find new interests. 60．What is the best title (标题) of the text? A. Dreams Are Important B. How to Find Your Dream C. Make Your Dream Come True D. Students Have Many Dreams D Every Monday, Mike comes to his father’s cookie shop to make 40 chocolate cookies. He does that carefully to make them yummy. Then, he and his father take the cookies to Old People’s Home. The cookies are for the old people there, one for each. Each time, a cute cookie elf (小精灵), watches the kind father and son quietly. One Monday, John, a businessman, comes. “Your cookies taste like my grandma’s! They’re so delicious!” he says. “I want to buy your recipe (食谱) and you can have lots of money!” “Really?” Mike says. "But we just use a usual recipe." “No secret (秘密)?”John asks. “No. I don’t think so.” Mike says. Mike’s father nods（点头） to show Mike is right. “I know what’s the secret!” the elf laughs. John finds one cookie and puts it into his bag. “I’ll find the secret,” he says, then he leaves. Seeing this, the worried elf makes a new cookie. Quietly, she puts it into the basket. At Old People’s Home, Mike and his father give cookies to the old people again. The last grandma gets the cookie made by the elf. “It tastes more delicious! You must put more love into the cookies today.” the grandma smiles.
