Question

畫(huà)出作定語(yǔ)修飾名詞的分詞短語(yǔ)。

The river polluted by the chemicals from the factory has been a cause of disease in this city．

Answer 1

答案：
解析：

The river polluted by the chemicals from the factory has been a cause of disease in this city．本句的主干是The river has been a cause of disease in this city．這條河已經(jīng)成為這個(gè)城市疾病發(fā)生的一個(gè)原因。polluted by the chemicals from the factory修飾the river，指明是哪一條河，由于pollute和river之間是被動(dòng)關(guān)系，因此用的是過(guò)去分詞短語(yǔ)。
