Dave is my friend. His family is rich. His parents always give him lots of pocket money. But Dave thinks his parents work very hard and it's not easy for them, so he always tries his best to save money. He has some good ways to do it.

    Dave likes reading. He has lots of books. He tells me he often buys books online, because they're cheaper. And when he has free time, he often goes to bookstores or libraries to do some reading.

    Dave has a bike. He usually goes to school by bike instead of taking a bus. Sometimes when it rains or snows, he walks. These two ways help Dave keep healthy and save some money.

    Dave brings a bottle of water to school every day. When other students drink juice, he enjoys his water. He thinks water is the cheapest but the best drink.

    Some students think Dave is mean. But I don't think so. I think he is right. What do you think of him?

Dear Tom,

    Most of the time, I just stay at home for my vacation. That's too boring. But I had a special and exciting vacation last summer. My classmates and I made a trip to Mount Tai by bus.

    When we arrived there, it was dark(天黑). At 7 pm, we began to climb the mountain. It took us the whole night to get to the top of the mountain. On the morning of the next day, we enjoyed the beauty of the sunrise on the top. That's wonderful. In the daytime, we visited a temple (寺庙). In the evening, we had a big dinner in a local restaurant together. The food there was delicious but a little expensive.

    I hope you can come to China next year. Then we can visit more interesting places together.

Yours,

Mike
