英语necessary的问题
It is necessary for us to learn.可不可以改成
We are necessary to learn

英语necessary的问题It is necessary for us to learn.可不可以改成We are necessary to learn
It is necessary for us to learn的结构是it做形式主语,真正的主语是后面的“to learn”.如果把句子顺过来说就会变成To learn is necessary for us,或者Learning is necessary for us——学习对于我们来说是必需的.
如果说We are necessary to learn,主语就变成“我们”,后面的to learn不再是主要结构的一部分,于是主系表结构的意思为“我们是必需的”,显然不通.
因此,这个是不能改的.

nope. necessary means "a need" , so it's like :it's a need for us to learn, not : we are a need to learn? it just doesn't make sense.

no...
It is necessary for us to learn
we are required to learn

不可以。因为人不可能被叫做necessary。
