Step 2 Grammar time
1. T: Now, boys and girls, turn to page 60, look at the questions.
T:出示Grammar time 的完整图片。
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。
