【題目】In the past, many rivers were ______________(污染) seriously, but now they are cleaned up.

【答案】polluted

【解析】

句意：在過(guò)去，許多河流被嚴(yán)重污染，但是現(xiàn)在它們被清理干凈了。

“污染”可用pollute表示，動(dòng)詞；分析句子可知，本句主語(yǔ)many rivers是動(dòng)作pollute的承受者，此處應(yīng)使用被動(dòng)語(yǔ)態(tài)結(jié)構(gòu)，所以用其過(guò)去分詞形式。故填polluted。
