Travel is something that people do every day. It is very difficult to avoid the need to travel. It may be a trip
to school, university or to work. Travelling can often take a long time, especially when great distances need to be
covered. People often enjoy travelling abroad for holidays. However, for some people travelling is not fun at all.
Some people suffer from travel sickness. This means that they will become unwell each time they travel.
Travelling can be either affordable or costly. It often depends on how far you want to travel and the choice
of transport. Using a bicycle will not cost anything as you power it by using your legs. However, the use of a
bicycle can be hard work and can take a lot of time to travel long distances. Cars and motorcycles are faster
modes of transport, but are more expensive to use as gasoline is needed for them to work. It can usually be
assumed that the longer you wish to travel, the more expensive and time consuming it will be.
The use of a plane is necessary for people wanting to travel very long distances. A pilot will fly a plane
from an airport for many thousands of miles to take people to places far away. Although traffic is rarely a
problem for airplanes, it can take a lot of preparation to travel by plane. People often need to arrive at the airport
three hours prior to departure.
A train is another mode of transport which is ideal for travelling long distances within the same country, or
between countries which are connected by land. A train driver will stop at train stations on route to allow
passengers wishing to proceed to the scheduled destination to board the train.
A number of destinations can be travelled by using the sea. People often depart from a harbour in a ferry
which is driven by a captain. If the journey is a long distance, people may choose to sleep on the ferry while they
wait to arrive at their destination. Some people choose to go on a cruise for their holiday, which would involve
stopping at many different city ports for a short amount of time. People who need to travel short distances may
choose not to use any transport at all. People often rely on their legs to take them to places nearby and they walk.
This is often encouraged as certain modes of transport have been said to produce harmful emissions and damage
the environment.

4. If the journey is long, people can spend the night on the ship, waiting to arrive at their destination.
5. People who do not want to travel far, can’t use transport.
6. Some types of transport don’t harm the environment.

Русский ученый М.В. Ломоносов писал о времени Петра: «При Петре Великом не одни бояре и
боярыни, но и буквы сбросили с себя широкие шубы». Как вы думаете, что хотел этим сказать М.В.
Ломоносов?

Некоторые исследователи считают преобразования Петра I не чем-то новым, а продолжением
начавшихся во второй половине XVII в. процессов. Какую точку зрения вы разделяете? Свое мнение
обоснуйте письменно.*
