不对.
It is high time we should make people more aware of the fact that environmental protection is vital to us.
最好是：
It is high time we raised the level of people's awareness of the importance of the environmental protection
It is high time we raised people's awareness of the importance of the environmental protection"It is high time we should" 不是固定句型吗？要改成过去式？ 我句子里的that后面做people的同位语不可以吗？麻烦详解我句中的错误？最好举个例子哈。俺底子薄。先谢了这个句型中的虚拟语气的动词形式虽有should+ 动词原形的， 但用动词过去式更为常见
