初级英语和逻辑问题
Once a man wanted to go from one side of a river to the other in a boat.He had to take with him a sheep,a wolf and a basket of vegetables.But he could take only one of them at a time,because the boat was very small."If I leave the wolf and the sheep together,the wolf may eat the sheep," he said to himself."If I leave the sheep and the vegetables together,the sheep may eat the vegetables." He thought and thought.At last,he had an idea.And he was able to get to the other side of the river.Do you know how he did it?
He had to take with him a sheep,a wolf and a basket of vegetables.这句的意思是不是“他要带上一只羊一只狼和一篮蔬菜”?那him用在这里是怎么回事?如果是他的一只羊那不是应该用his吗?或者干脆直接He had to take a sheep.../He had to take with a sheep...
就是文章最后一句话,他如何那3个事物都安全带过去的?如果先带羊,那第二个不管带狼还是蔬菜都不行啊.文章就这么短,
