【答案】

1polluted

2possibility

3crowded

4risks

5disadvantages

【解析】

1句意:被污染的空气和水对人们的健康是有害的。名词 air and water,与pollute之间是被动关系,故用过去分词。故答案为:polluted

2句意:有可能你在周末前回来吗?这里缺少句子的主语,谓语动词是单数形式is,所以这里应该用名词单数形式。故答案为:possibility。

3句意:我们要上的这辆公交车太拥挤了。空格前有was,所以这里应该用形容词,crowded形容词,“拥挤的”。故答案为:crowded

4句意:这种方法有种危险,在家不要尝试去做。根据谓语动词are,可知,句子的主语应该是复数形式。故答案为:risks

5句意:这台机器有两个严重的缺点,因此我们必须找到方法来改善一下。空格前有数词two,所以空格处应该用名词的复数形式,advantage优点;根据must find some ways to improve them可知要改善的应该是缺点,disadvantage缺点。故答案为:disadvantages
