One morning, Mrs Black was going to do some shopping with her daughter, Mary. When they were walking in the street, Mrs Black was knocked down(撞倒) by a fast car and was quickly taken to a hospital.
The next day the driver came to the hospital to see her with a bunch of flowers. But Mrs Black was weak and could hardly(几乎不) speak, so her daughter went in and spoke quietly to her mother, "Mother, the young man who knocked you down is waiting outside. May he come in?" "Yes, " Mrs Black also spoke quietly, " If he is on foot."
