     In England, people don't usually talk very much. You can get on a bus or a train, and everyone likes

looking out of the window. Often they read books and papers. But they don't talk much.

     When you meet English people, they often talk about one thing-weather. So  when  you  meet your

friends in England, you can say," Nice weather for the time of this year ! "

    "But it was a little cold yesterday. " Someone may answer.

    "But it got a bit warmer later!" You can say.

     Talk like this, and the English will think," How friendly you are!"

     It is never too hot or too cold for working or living in England. This is because of the sea. It keeps

the country warm in winter and cool in summer. The weather changes very often in England. One can

never has the same kind of weather for a long time. In spring, sunshine and rain follow each other quite

often during the day. So when one goes out, he must never forget to take an umbrella.
