根据短文内容回答下列问题
A city without cars would be very strange, right?
But Venice is such a city.
Venice is in the northeast of Italy. It isn't
built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater
is everywhere around the city.
Even so, travel isn't difficult. The
waterways have always been the best way to get around. There are 117 waterways
and more than 400 bridges that can lead you where you want to go.
People in Venice move from place to place
by boat. They like to enjoy cool summer nights while taking boat trips. They
can talk to other people as they go along.
Venice grew out of small islands in
saltwater lakes when some Italians escaped(逃跑)from
a war more than 1,500 years ago, and built homes there.
Water makes the city special, but it is also
a big problem.
Once, people used too much underground
water. This made the city get lower, little by little. Now the city has gone
down by 23 centimetres.
Another problem is the rising seawater. The
temperature has risen over the years. This has made arctic(北极的)ice melt.
Scientists are trying different ways to
stop the city from getting even lower.
