1.As he thought he could sell the jar and get some money for it,he immediately opened it.
2.The boy rushed out and almost knocked me down.
3.I'm very interested in geography,so I find it quite easy to learn it well.
4.I heard someone calling my name.
为什么我老是不懂改呢?哪里是要点呢请告诉我吧,谢谢.
就是句子里边有分词的结构，原意不变。

答案

改为：1.HAving thought he could sell the jar and getting some money for it,he immediately opened it.要点：当主句和从句的主语指同一人或同一事物的时候,从句中的谓语动词就可以用分词.分词有现在分词和过去分词,表示主动的用现在分词,表示被动的用过去分词,分词在时间上有一般式和完成式,与谓语动词同时发生用一般式（doing）,发生在谓语动词之前用完成式（having done).
2.The boy rushed out ,almost knocking me down.要点同上
3.Being interested in geography,I I find it quite easy to learn it well.要点同上
4.I heard someone calling my name.此句本身就是现在分在分词作宾语补足语,hear sb.doing.不需要再改.
