25. 主语从句 1．What we need is more time.我们需要的是更多的时间。 2．Who will go is not important.谁去都不重要。 3．Whether she’ll come or not has not been decided yet. 她来不来还没有定。 注意：(1)从句作主语，谓语动词用单数。 (2)主语从句中表“是否”用whether，不用if。 (3)从句作主语，为避免“头重脚轻”，可用it作形式主语，而将从句放在后面。 例：It is a pity that she has made such a mistake. 她犯了这样一个错误，真是遗憾。
