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 rubb ( http: / / www.21cnjy.com )ish 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。
