Read the text:
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 they 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 to 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.
Read the text again and write if the following sentences are True or False:
1. Travel is something that people don't often do.
2. People like to spend their holidays abroad.
3. Sickness means that people will become unwell each time they travel.
4. Cost of travelling often depends on distance you want to travel and the type of
transport.
5. If you want to travel very long distances you should use a car and motorcycle.
6. People often need to arrive at the airport about an hour before the departure.
7. If you need to travel foe a long distances within the same country, or between
countries which are connected by land you can use a train.
8. Sometimes people choose to go on a cruise for their holiday, when a ferry can
stop at many different city ports for a short period of time.
