或:Mr Li is an 80-year-old man without children. He feels lonely from time to time. Also, he is too
weak to do the housework. To make things worse, the supermarket is too far away for the old man to
do the shopping.
I am writing to ask you to help him. On the Charity Day, we can go to Mr Li's house to help with
the housework. We can also talk to him or read the newspapers for him. What's more, we can do some
shopping for Mr Li.
I hope all of us can give a helping hand so that Mr Li will feel less lonely.
