Postcard From Canada

Dear Weihan,

      Hi from Canada! We are having a wonderful holiday. We haven't seen a bear yet, but there are bears

and deer in the forests around the lake where we're staying. The bears often go to the rubbish dump (垃圾场)

to look for food. Perhaps we'll go to see them at the dump. We will need to be careful because bears are

quite dangerous. They will attack if you surprise them, so people carry bells (铃) when they are out

walking to warn the bears away.

     On our first night we saw a fireworks (烟火) show. It doesn't get dark here until 10 o'clock, so it was

a really late night for us.

      Today I had a very short swim in the lake. It was cold. The weather has been sunny, but not like the

weather at home.

     Bye for now. We will be home next week.

                                                                                                                                            Yours
