Mrs Black was having a lot of trouble with her skin (皮肤),so she went to her doctor about it.He could not find anything wrong with her,so he sent her to the hospital for tests.The hospital,of course,sent the result of the tests to Mrs Black's doctor,and the next morning he telephoned her to give her a list of the things that he thought she should not eat,because any of them might be the cause of her skin trouble.
Mrs Black carefully wrote all the things down on a piece of paper,which she then left beside the telephone while she went out to a party.
When she came back home several hours later,she found her husband waiting for her.He had a basket full of packages （包）beside him,and when he saw her,he said,"Hello,dear.I have done all your shopping for you."
"Done all my shopping?" she asked in surprise,"But how did you know what I want?" "Well,when I got home,I found your shopping list beside the telephone and bought everything you have written down."
