听力原文： TUVALU, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the sea. Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five meters above sea level. Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country's days are numbered. But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy, best known for its canals, has sunk about 24 cm over the past 100 years.
Experts say that it will have sunk another 20-50 cm by 2050. A century ago, St. Mark's Square, the lowest point in the city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands. Tuvalu's rising sea level is caused by global warming. The average global temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years. The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.

听力原文： Never a very confident man, Hanley was happy to leave all the arrangements for the exhibition to his agent, a young man by the name of Green, who had a talent for organization. Green had been to his studio and, with the help of Hanley's wife, had selected the pictures for the exhibition. He had decorated the hall and had personally supervised the hanging of the pictures. Most important of all, he had seen to it that all the invitations went to the right people: critics, reporters and, of course, people with money to spend on paintings.
"There's no doubt about it," Green assured him during the exhibition," everything has gone off very well. "Hanley was pleased, but remained shyly in the background, unwilling to meet his public.
"One picture caught special attention. "Green told him. He consulted his catalogue. "Number thirty-seven. It did not have a name, so your wife and I decided to call it' Midnight'-- because all the colors are very dark."
Hanley, unable to recognize the picture from this description, was puzzled, but he said nothing. When everyone had left, he slipped across to see for himself the painting which had attracted so much attention. He laughed so much that Green came across to see what the matter was. Trying hard to suppress his amusement, Hanley told him that one of his son's paintings had been hung up by mistake.
