Read and listen. Find two advantages of the metro system.
Travel round Hong Kong The Hong Kong Metro (MTR) is very popular. It is one of the cleanest and most comfortable metro systems in the world. However, there are some strict rules to make sure that it stays this way: • You must have a valid ticket to travel. • You mustn’t eat or drink on trains. Fines are up to HKD$5,000! • You must stand behind the yellow line on the platform. • You mustn’t take bikes on trains. • You mustn’t shout. A guard may ask you to leave the train if you do! • You mustn’t play musical instruments, dance or sing on trains.

Read and listen. What are the best parts of a pilot’s job?
I have to travel a lot. Sometimes I have to travel thousands of miles and work in different time zones on the same day. A pilot must concentrate at all times. I’m responsible for a lot of people so I mustn’t get distracted. I don’t have to reserve a seat when I travel on another plane because there is always an extra seat for a pilot. And I don’t have to wait for my bags, so I can leave the airport really quickly!
We use have to or must + the infinitive to talk about obligations: I have to travel a lot. A pilot must concentrate. We use mustn’t to talk about an obligation, BUT we use don’t have to when something is not necessary and we have a choice: I mustn’t get distracted. (This is a rule.) I don’t have to reserve a seat. (It is not necessary.) 2 Read and circle the correct word. I’m a flight attendant. I (a) have to / mustn’t take care of people on the plane. Before take-off, I (b) have to / mustn’t explain the safety instructions carefully. Some people think they (c) mustn’t / don’t have to listen, but the instructions are very important. If a passenger becomes really ill, the plane (d) must / doesn’t have to land at the nearest airport. We (e) mustn’t / don’t have to panic. One great thing about my job is that I (f) mustn’t / don’t have to work every day. Sometimes I (g) mustn’t / don’t have to fly back immediately and I can visit a new city.

Australia is an enormous country and some people live hundreds of miles from a city. If they get ill, they (a) have to / must see a doctor, but this can be difficult. If people can’t travel to a city, the Flying Doctors (b) fly to them. The doctors (c) fly the plane because a pilot always goes with them. You pay for the service because (d) it’s free. There are about 60 planes to take doctors all over Australia, so people who are ill (e) wait long for help. Many remote areas also have a medical chest. Before you use it, you (f) speak to a flying doctor by phone. And you (g) use the medicine for animals, it is only for people.
