任务型阅读 （共10小题，每小题1分，计10分，每空一词。） What’s the most important thing in your life? Have you thought about this question? I began to think about it when I was just a little girl. I had a lot of friends and I loved playing with them. So I thought friendship was the most important thing in life. If I had no friends, I would be very sad. When I got older, I thought the most important thing was music. I was crazy about music at that time. In my opinion, if I couldn’t sing or couldn’t listen to music, my life would be meaningless. As time went by, I changed my mind again. When I was 12, I read a book that tells a beautiful story about the love between a mother and her child. I was happy to find that love was the most important thing. I thought love made my life beautiful. Not long ago, I got a new answer to the question from another book. The writer said, “happiness is the destination for everyone.” Soon I realized that, in fact, friendship, music, love and happiness are all very important to us. There are many important things that make our lives colourful and beautiful. What’s the most important thing in life? I don’t have the answer yet. However, in fact, I don’t want to know. I just want to care about everything important in my life. And I believe I will be very happy if I can achieve that. I hope everyone can find the important things in their lives, and cherish them!
