Ask and answer in pairs.Act out二Grammar time出示Grammar time 的完整图片。1.分大组进行问答，能熟练问答。2.语法要点归纳：1)What 作为疑问词看作是单数，所以动词make使用了第三人称单数形式。2)Smoke 和rubbish都是不可数名词。一般现在时的肯定句中，主语是不可数名词，谓语动词也用第三人称单数形式。3)Make和keep的不同用法：Make 的意思有很多，做，制作，制造，整理，获得等，在本单元中的意思是“使变得”，make+sth/ sb+形容词 。如：Smoke from cars makes the air dirty. 汽车排出来的烟使空气变得肮脏。Rubbish makes the steeets messy and dirty. 垃圾使街道杂乱无章。Keep的意思是保持，经营，饲养，遵守等，本单元中的意思是“保持”。例如：We can put rubbish in the bin to keep our city clean. 我们把垃圾放进垃圾桶能让我们的城市保持干净。Trees help keep the air clean. 树木有助于空气保持清新。三.Make some sentences.
