I'm a student of Grade Seven. Now I (read ) a book about the time difference(时差). It's very interesting. Let me give an example. It's one o'clock in the early morning in Beijing. are the people in different countries doing?
In London, some people are leaving work to go back to (they) houses. Some people (shop) in the supermarket.
In Moscow, some people are taking walk in the park after dinner. Some are going to the (movie). Some are drinking in the pub(酒吧).
It's morning in Los Angeles. People are working in the office. Some (child) are studying at school. How New York? It's noon. People aren't working but (have) lunch. They are eating hamburgers, hot dogs or other foods. Some people are meeting friends. Everyone wishes (have) a happy day.
