An exciting trip （激动人心的旅行）
I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.

An exchange visit is
educational and interesting!
“I was very nervous at first,” says Sarah. “However, my host family are really friendly. I’m glad to be a guest in their home. I’ve learnt to use chopsticks, and they’re teaching me a little Chinese!”
The students spend the weekdays studying with Chinese students. At the weekend, they tour around Beijing and visit places of interest with their host families.
“It’s been a fantastic experience so far,” says Eric. “I’ve learnt a bit of t’ai chi, and I really enjoy it. We’ve already learnt a lot about Chinese culture and history. The teachers have introduced us to Chinese painting as well. We’ll also try to paint some pictures ourselves! I haven’t had much success yet, but I’ll keep trying.”
“I’ve made many new friends,” says Sarah. “I plan to keep in touch with them when I return home. We’ll see one another soon because they’ll come over to the UK for the second part of the exchange next month. I can’t wait!”
A group of British students from Woodpark School in London are visiting Xinhua Junior High School in Beijing on an educational exchange.

Lesson 28 No parking 禁止停车
Jasper White is one of those rare people who believes in ancient myths. He has just bought a new house in the city, but ever since he moved in, he has had trouble with cars and their owners. When he returns home at night, he always finds that someone has parked a car outside his gate. Because of this, he has not been able to get his own car into his garage even once. Jasper has put up ‘No Parking’signs outside his gate, but these have not had any effect. Now he has put an ugly stone head over the gate. It is one of the ugliest faces I have ever seen. I asked him what it was and he told me that it was Medusa, the Gorgon. Jasper hopes that she will turn cars and their owners to stone. But none of them has been turned to stone yet!
