The hole in the Earth's ozone layer has until now protected Antarctic from the worst effects of global warming, but scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3degC on average, with melting ice contributing to a global sea level increase of up to 1.4 meters. In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, , been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctic, making much of the continent surface colder than usual. But now that the gases that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3degC and a reduction in sea ice by around a third. The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctic ice sheets, said, "The ice sheets in Antarctic are hundreds of meters thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly." Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctic has already resulted in a 10% rise in global sea level in recent decades. Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected----Antarctic may be a long way away but it is an important part of the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough, if it melts completely, to raise sea levels by 63 meters." Even in a worse-case situation scientists don't expect the ice to entirely disappear, but... Which of the following is true according to the passage? A) Antarctic is currently experiencing the full effects of global warming. B) The average temperature has increased by 3degC in recent decades. C) Antarctic contains most of the world's fresh water. D) Ten percent of Antarctic's ice has already been lost.

The Channel is the name given to the stretch of water which separates England and France. Ferries 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 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. The word hazard is closest in meaning to _ . A) trouble B) danger C) enemy D) problem
