知识要点一:

I'll help to clean up the city parks.

我将帮忙清理城市公园。

(1) clean up意为“打扫(或清除) 干净”，而clean则含义较单纯，意为“打扫；把……弄干净”。例如：

放学后我们必须把教室打扫干净。

(2) 经常与up连用的短语还有：

set up“建立； 创立；开办”

cheer up“使高兴起来”

think up=come up with“想出”

注意:clean up，cheer up，set up，call up，fix up，look up，put up和think up都是由动词和副词构成的动词词组。若代词作宾语则必须放在动词和up之间；若宾语是名词，则名词放在up之前或之后皆可。例如：

Please clean up the classroom before going home.

回家前请先打扫好教室。

When I was ill，several friends sent me flowers to cheer me up.

当我生病时，有几个朋友送给我鲜花使我高兴起来。
