Чем поле отличается от природной экосистемы?

1. Jane usually goes to work by bike or on foot.
2. The plane is flying at 600 miles an hour.
3. How long does it take from New York to Los Angeles by plane?
4. Get on the train! Quick! It's ready to leave.
5. We traveled from Paris to Moscow by train.
6. I didn't use my car very often. I prefer to go on my bike.
7. I saw Jane this morning. She was on a bus which passed me.
8. I didn't feel like walking, so I came home in a taxi.
9. At last the bus arrived and I got on the bus.
10. I have to get on (off?) the train at the next stop. (get on - сесть в поезд, get off - выйти. Второе логичнее, но такого предлога нет в задании)
11. Let me help you to get your things in the car.
