     The Channel is the name given to the stretch(伸展) of water which separates England and France.

Ferries(轮渡) operate all year round to carry people across the Channel, and they are busy most of the

year. January is the only quiet month nowadays. As well as summer holiday-makers, there are day trippers and coach traffic, not to mention lorries and other commercial vehicles. Some ferries carry cars and their

passengers, while others also connect train passengers with the continental rail network.

     The biggest hazard for the ferry is the wind. The crew listens to BBC weather reports four times a day. Or they sometimes get gale(wind) warnings from local radio station.

     Crossing the Channel by ferry is a bit like trying to cross Oxford Street on a busy afternoon, according to one ferryboat captain. The ferries from Folkstone and Dover to Calais and Boulogne have to cross the main flow of traffic. This consists of ships traveling through the Channel to and from Northern Europe.

There may be four hundred ships making the journey at any one time, and they all pass through a "choke

point" which is only fifteen miles (twenty-five kilometers) wide. The cross-channel ferries have to sail right

through the middle of all this traffic.
