That-从句作主语通常用it作先行词，而将that-从句置于句末，例如： It is true that the earth is round. It's a pity that you should have to leave. 你非走不可真是件憾事。,Attention,2.表示“是否”意义时，一般用whether 而不用 if引导主语从句， Whether she will come or not is still a question . 但如果有形式主语 it引导时，既可用 whether，也可用 if。 e.g. It is still a question if she will come . 3.有时可用形式主语it 代替主语从句： e.g. It is still a question whether she will come .
