选哪个? 顺便解释一下~ THX!
water pollution; the polluted water
exchange for
第一个是水污染,应该用污染的名词形式。。
第二个是过去分词做形容词,表示被污染的水
had somebody do something
因此要用动词原形。exchange sth for sth.表示用某物交换某物
C. pollution, polluted
第一个pullution是名词,water pollution是水污染的意思,第二个pullted是动词,意思是被污染的水。
B exchange, for
have sb do sth是个固定用法
句子意思是哪个男孩很淘气,他让女孩用玩具换了他的糖

b
have sb do sth 是固定搭配,意思是让某人做某事,与let,make用法相同.而exchange for 意为交换
