When animals make long journeys across places where there is no food or shelter, such as deserts or oceans, it is very important that they should be able to find their way accurately.
Birds find their way by the stars at night and by the sun during the day. People thought that this was impossible. Then some scientists made an experiment. They put some migrating birds(候鸟)in cages inside a planetarium(天象图). When the operator turned the artificial sky(人造天空)round, the birds began to fly to the sides of the cage. Every time he moved it, the birds moved to a new position. Scientists discovered that they always flew toward the direction in which they would have flown if the sky had been real. This proved that they could see the stars and respond to them.
Many animals, especially birds, have a very precise sense of time, which is called their “internal clock”. In cloudy weather, birds delay setting off on long journeys, but if the cloud lasts for a long time,
A. Birds find their way by the stars at night and by the sun during the day.

C. Birds can see the stars and would move when the stars change position.

[单项选择]When a customer claimed to have found a severed finger in a bowl of chilli served at a Wendy’s fast-food franchise in California, the chain’s sales fell by half in the San José area where the incident was reported. Wendy’s brand and reputation were at risk, until the claim was exposed as a hoax in late April and the company, operator of America’s third-biggest hamburger chain, was vindicated.
Yet the share price of Wendy’s International, the parent company, rose steadily through March and April, despite the finger furore and downgrades from analysts. One reason was heavy buying by hedge funds, led by Pershing Square Capital. This week Pershing made its intentions public, saying that it was worried by market rumours that Wendy’s might soon buy more fast-food brands, and arguing that the firm should be selling assets instead. Pershing’s approach indicates rising pressure on American restaurant companies to perform, at a time when the industry’s growth prospects look increasingly tou
