Ⅰ. 词汇串记
　　Of all the subjects, I like chemistry best, which is
about how substances react with each other. I
learned from the lesson that water exists as solid,
liquid and gas. Metals will expand when heated and
contract when cooled. Most substances belong to mixture. Most metals have reaction with oxygen, which produces oxide. For example, iron will rust in the open air. Our teacher tells us that when we do an experiment, we should make sure what aim we will get, then how many stages it includes, and at last what conclusion we can get. Ⅱ. 句式背诵
