in village A, we saw many chemical factories standing here.这句话用的是什么时态??
but unfortunately we slso found many villages had suffered from diseases caused by polluted air and water.这句呢?
have been tried这个是不是现在完成时态的被动?
standing现在分词修饰FACTORIES ???什么意思?
but unfortunately we slso found many villages had suffered from diseases caused by polluted air and water.这句呢?
have been tried这个是不是现在完成时态的被动?
standing现在分词修饰FACTORIES ???什么意思?
in village A, we saw many chemical factories standing here.这句话用的是过去式，你要看谓语动词SAW，（see）
standing现在分词修饰FACTORIES
第二句要看主句的谓语动词FOUND（find）,也是过去式
have been tried这个是不是现在完成时态的被动?
要看具体语境。
如 the boy have been tried to skip class是现在完成时态的被动
in village A, we saw many chemical factories standing here.是一般过去时
but unfortunately we slso found many villages had suffered from diseases caused by polluted air and water主句是一般过去时，从句是过去完成时
have been tried是现在完成时态的被动语态
