suppose
1.下面每组里的三句意思相同，第一句最普通：
- I suppose (that) he is about forty.
I suppose him to be about forty.
I suppose him about forty. - It was then supposed that she was dead.
She was then supposed to be dead.
She was then supposed dead.
2.下面每组里的两句意思相同：
- Suppose he is absent, what shall we do?
Supposing he is absent, what shall we do? - Suppose he were absent, what should we do?
Supposing he were absent, what should we do?
Suppose属于祈使语气，supposing是现在分词。有人以为用suppose比用supposing好。注意第一组的两句里都用is absent，不用will be absent。
3.比较下面每组里的两句：
- Suppose we look him up today.
Suppose we looked him up today. - Suppose you look him up today.
Suppose you looked him up today.
每句都表示建议，每组里的第二句比第一句婉转。
4.Suppose you come to my house tomorrow morning, and I will show you all my books里的suppose表示建议。
