本题考查非谓语动词作定语,一定要记住,过去分词词组表被动,不可以带be动词.
considered impossible in the past=that were considered impossible in the past.
前者为过去分词作后置定语,后者为定语从句,语法功效一样.
many things considered impossible in the past are quite common today 为什么 不用be conaidered 不是被动吗 be done吗 be 呢
many things considered impossible in the past are quite common today 为什么 不用be conaidered 不是被动吗 be done吗 be 呢
