12、2.条件状语从句（真实条件句）： 用if引导，假设很有可能发生，主句常为将来时或祈使句或情态句，从句常要变为一般时。 without后加名词也可以看成是个省略的条件句。 例如：If he is sleeping, dont wake him up. I will tell him the news if he comes. If you give me a fulcrum (支点), I can pry the earth.Without water, people cannot live.五、反思和练习1.对学生表现作出肯定评价并鼓励学生继续进步2. 71页的选择题，背课文和单词。3.记新单
