主语从句,what is Britain now作主语.你可能有点混淆it作形式主语时的区别.举个例子
主语从句---What I said was important.(翻译:我所说的很重要).慢慢体会what放在句首的味道.可以反过来读 I said what(当然英语中没这种说法,是句子成分划分时才用,主语I 谓语said 宾what).what I said可以看成一个句子,可以在心里悄悄的当做It(形式主语it) ,此话就简单为it is important.简单吧?
另外有些特殊句式必须用It作主语.It is +adj+ to do sth
It is important to learn English well.
建议:英语多读课本多背书,读到一定境界直接就知道.无需太花功夫纠缠语法.
因为选A是错误的,所以不选A了
what is Britain now是作主语,表示:我们现在所说的英国
这是一个主语从句啊。 what is british now 是主语,所以不能用形式主语it
what引导的是主语从句。句子中缺少成分所以用what` it引导的是形式主语句~要看句中有没有它指代的部分,此句中没有,所以用what·
