语法不好,请大家帮忙

第二行中it was a bad new不对，应该是news，新闻就是news,不可数，改为it was a piece of bad news
同样第三行的were改成was

第二段应该是focused on
are related 后面不是with应该为are related to

第三段第一行末位的suspected是及物动词，后面要接宾语，你可以加一个it，然后再加上for 再接several years

Although very high does artificial may leaded to bladder cancer in animals,
这句话整个都有问题！！不知道你的原意是什么，不好作修改

剩下的没有什么错
