We heard it that she would get married next month.

We think it possible that the price will rise.

注意：1. 关系词that常可以省略;

2. 介词宾语用whether, 不用if;

3. find / make / see / hear / feel / think... + it + adj. / n. + that ...句型中, it 作形式宾语, that引导真正的宾语从句, 不能省;

4. 若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。

I don't think (that) the film is interesting.

I don't think this dress fits you well. 我认为这件衣服不适合你穿。

5. be sure / certain / glad / afraid / sorry / pleased + that ...句型中, that 可以省;

6. what is / was the matter /wrong with sb作宾语从句, 不改变语序;

Who knows what is the matter / wrong with him?

7. 有两个或两个以上宾语从句时, 第二个和第二个以后的从句必须用that引导.

She said she was pleased at her victory and that she would work harder.
