新人教版九年级英语下册Unit 13 We’re trying to save the earth!教案
Unit 13 We’re trying to save the earth!教案一、时态复习1. 一般现在时一般现在时表示经常性或习惯性的动作，常与often, usually, always, sometimes, everyday 等时间状语连用。
一般现在时中，当主语是第三人称单数时，实义谓语动词应在其后加s 或es；构成疑问句或否定句时借助do，don’t或does，doesn’t，谓语动词应用原型。
例如：Lucy always goes to work on time. 露西总是按时上班。
Does he usually watch TV in the evening? 他晚上经常看电视吗？2. 现在进行时现在进行时由“be动词(am is are)+现在分词”构成，其中现在分词的构成为：一般在词尾加-ing；以重读闭音节结尾的动词，若末尾只有一个辅音字母，要双写这个辅音字母，再加-ing；若以不发音的字母e结尾的动词，则去e加-ing。
现在进行时的句式变化如下：肯定式：I’m reading. 我在读书。
否定式：I’m not reading. 我没在读书。
疑问式：Are you reading? 你正在读书吗？3. 一般将来时由助动词shall，will或be going to加动词原形构成。
shall用于第一人称(尤其在疑问句式中)，will通常用于第二、三人称，也可用于第一人称的陈述句式中：be going to用于所有人称，表示计划、打算、准备要做的事情或即将发生或肯定要发生的事情。
一般将来时的句式变化如下：肯定式：We shall go. 我们要走了。
否定式：We shall／will not go. 我们不会走。
疑问式：Shall you go? 你(们)要走了吗？4. 一般过去时由动词的过去式表示，动词的过去式分为规则和不规则形式两种。
规则形式变化为：一般在原形末尾加-ed；以e结尾的加-d以重读闭音节结尾，末尾只有一个辅音字母的，双写结尾的辅音字母，再加-ed，结尾是辅音字母加-y结尾的，变y为i，再加-ed。

九、练习及作业设计
Exercise
根据句意用take, spend, pay或cost的适当形式填空。
1)That new car ________ them lots of money.
2)Mona __________ 50yuanon the books just now.
这一课的听力是对上一节课内容的延续与拓展。因为上一节课的铺垫，学生对话题熟悉，所以听力部分并不难。但是，九年级的学生不喜欢发言，这对我如何上好2d的对话训练提出考验，鼓励与前面的知识铺垫是必不可少的。
三、教学目标
1. 语言知识目标：
1) 能掌握以下单词及短语：coal, ugly, cost, wooden, plastic, takeaway, bin
2）句型The air is badly polluted.
2. 情感态度价值观目标：
