Task 1. Read the text. Transport There are as many means of transport as you can only imagine. They are a bus, a bicycle, a car, a ship, a train, a plane and so on. And today I want to discuss all of them. The most popular means of transport is a car. Nowadays there are so many car producers and brands that a car becomes the most popular and comfortable type of transport. You can travel by car everywhere. Another popular transport is a bus. The cost of travelling by bus is much lower than that of a car. Bicycle is popular among young people. They use it during the warm seasons to travel around the city or the nearby places. It's healthy and affordable for most of people. Train is popular for its low cost and cozy atmosphere. You can make a long travel on the train and don't need to pay a lot for it. Plane is popular for its speed but the cost is quite high. The most luxurious means of transport is a ship. I mean not those small ordinary ships, but the ones that travel across the oceans with thousands of tourists. They are often called liners. So we just need to pick up the one we like and completely enjoy it. Choose the correct answer A, B, C or D. 1) This kind of transport is healthy for people of all age. a) A bicycle c) A car b) A plane d) A train
