     Alex is going to study in Chicago for a year. He's reading a travel (旅游) book about the weather,

which says: it's usually cool in spring. Sometimes it rains. It's usually hot and sunny in summer. It's

normally cool and windy in autumn. It gets very cold in Chicago in winter.

     He asks himself, "What can I do there during that time? Oh, I can have a lot of free time in summer.

In autumn, I can't have a lot of free time because I'll be in school. I can play football. I can't go

ice-skating, because I don't know how to ice-skate. Then I can visit my family in Florida at Christmas

and New Year and get some sunshine. "
