Let's Clean Up!PPT，第三部分内容：Language Points
1. It's a special day to draw people's attention to the environment.

2. We should pick up that garbage!

pick up 动词短语，意为“拾起，捡起”，如果宾语是代词，应放于两词中间。例如：

例如：put on（穿上），take off（脱掉），turn off（关上），turn on（打开），put away（收拾好），look up（查词、字），try on （试穿）等，代词作宾语时放中间，名词作宾语放中间放后均可。
