1、It 用法导学案学习目标：熟悉课文中出现的it句型，能熟练运用并了解其他常见it句型。学习重点：it做形式主语和形式宾语 学习难点：运用it 句型学习内容： It表指代(人、事物、时间、距离、价值、天气、气候及温度等); It作形式主语、形式宾语； it引导的强调句、It表时间的固定句式。一It作代词v I am sending you some advice. _(它可能会帮助你）to stop and strengthen your resolve.(P18L29) 归纳：it指代_.练习: 1. There is a river along the village. _ (它能帮助村民）
