In this way，I can not only work it out but also improve my ability to overe problems all by myself.However，when it is something beyond my petence，I turn to my classmates or teachers for help. Sometimes I also ask my parents for advice. As a result I have made steady progress in my studies.预习自测：课文原句欣赏：1． think of a world without metals.很难想像一个没有金属的世界。

But the difficulty lies not in your English,but in your concept,as you have never thought yo u can do an experiment report in English.You are frightened.Su:Maybe so,I have not had the heart to start it,just because I don't think I can do it.Pt:Me too.SM:But you have done well in both chemistry and physics.You should be sure that you can do an experiment well not because it is in Chinese,but because you are able to do it well.So remember,you'll never know if you can do something unless you have the heart to h ave a try.You've got it?Su and Pt:Yeah,that's the very point.We'll go back and
