It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。
It is reported that China has sent another man-made earth satellite into orbit.
据报道中国又成功地发射了一颗人造地球卫星。
D. It+seem, happen等不及物动词及短语+that从句。如：
It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。
It happened that I was out that day. 碰巧我那天外出了。
E. It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。如：
It doesn’t matter whether she will come or not. 她是否来这无关紧要。
It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。
F. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。如：
Is it true that the scientist will give us a lecture next week? 下周那位科学家将给我们作报告是真的吗？
Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗？
G. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如：
How strange it is that the children are so quiet! 孩子们这么安静真奇怪！
2．注意连接代词whoever, whatever, whichever等引导主语从句的含义
Whoever comes will be welcome. (whoever=the person who) 来的人将受到欢迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正确的。
Whichever of you comes in will receive a prize. (whichever=anyone of you who) 你们当中不论哪个进来将会得到奖
