Mr.Tom Forester lived by himself a long way from town.He hardly ever left his home，but one day he went into town to buy some things in the market.After he had bought them，he went into a restaurant and sat down at a table by himself.When he looked around，he saw several old people put glasses on before reading their newspapers，so after lunch he decided to go to a shop to buy himself some glasses too.He walked along the road，and soon found a shop.
The man in the shop made him try on a lot of glasses，but Tom always said，"No，I can't read with these."The man became more and more puzzled （迷惑不解），until finally he said，"Excuse me，but can you read at all？"
"No，of course I can't!"Tom said angrily."If I was already able to read，do you think I would have come here to buy glasses？"

The shop Tom went into sold（）.
