单选题Directions: This task is the same as Task 1. The five questions or unfinished statements are numbered from 41 to 45. Why don't birds get lost on their long flights from one place to another? Scientists have puzzled over this question for many years. Now they're beginning to fill in the blares. Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly at night? Tests with artificial stars have proved that certain night -- flying birds are able to follow the stars in their long-distance flights. A dove had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star- filled sky. The bird tried to fly in the same direction as that taken by {{U}}his outdoor cousins{{/U}}. Any change in the position of the artificial stars caused a change in the direction of his flight. But the stars are apparently their principal means of navigation. When the stars are hidden by clouds, they apparently find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.

单选题 The Red Cross is an international organization which cares for people who are in need of help. A man in Paris hospital who needs blood, a woman in Mexico who is injured in an earthquake, and a family in India that lose their home in a storm may all be aided by the Red Cross. The Red Cross exists in almost every country around the globe. The world Red Cross organizations are sometimes called the Red Crescent, the Red Mogen David, the Sun, and the Red Hon. All of these agencies share a common goal of trying to help people in need. The idea of forming an organization to help the sick and wounded during a war started with Jean Henri Dunant. In 1859, he observed how people were suffering on a battlefield in Italy. He wanted to help all the wounded people regardless of which side they were fighting for. The most important result of his work was an international treaty called the Geneva Convention. It protects prisoners of war, the sick and wounded, and other citizens during a war. The American Red Cross was set up by Clara Barton in 1881. Today the Red Cross in the United States provides a number of services for the public, such as helping people in need, teaching first aid, demonstrating water safety and artificial respiration, and providing blood.
