Simon: Hey, Anna. This is Simon, calling from the Old Town of Lijiang!

Anna:  Hi, Simon! You are already in Lijiang! Great to hear you! So{#blank#}1{#/blank#}do you like the Old Town there?

Simon: Oh, we love it very much. You know it is so different from {#blank#}2{#/blank#}.

Anna: Really? How long are you staying there?

Simon: Four days. {#blank#}3{#/blank#}my dad has to go back to work next Monday. We arrived yesterday and visited the Old Town. Tomorrow we're going to Yulong Snow Mountain. {#blank#}4{#/blank#}save time, we're taking the cable car up there. If we still have time, we're planning to see Blue Moon Valley and Yak Meadow.

Anna: Sounds great! Oh, don't forget it's much colder on Snow Mountain. Be sure to keep {#blank#}5{#/blank#}!

    This term we have a new English teacher from Australia, Mr Green. He teaches very well and is {#blank#}1{#/blank#} to us.

    Last Sunday some of my classmates and I went to visit him. He cooked some Australian food for us. We taught him {#blank#}2{#/blank#} to use chopsticks and the way of making dumplings.

    He had an interest in making Chinese food. He also told us a lot of western customs(习俗). For example, when they have dinner in a restaurant together, they {#blank#}3{#/blank#} keep quiet.

    When it was time for us to leave, I said to him, "Come to my home for dinner when you have time." He looked happy and asked, "When?" But {#blank#}4{#/blank#} fact, I was just to be polite. From that, we could see the {#blank#}5{#/blank#} from country to country.
