Many residential burglaries occur because of widespread misconceptions. For example, while people typically worry about nighttime thefts, almost half of residential break-ins happen during the day, when homes are vacant because owners are working. Moreover, robbing a house probably takes less time than many people think. "Most burglars get in and out in less than ten minutes," says Jean O’ Nell, director of research and policy at the National Crime Prevention Council in Washington, D.C. And thieves are well aware that, even for properties with sophisticated security systems, time is on their side. Police can take five to 45 minutes to respond to an alarm or call, especially in rural or suburban areas where they may have considerable distance to cover.

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda(大熊猫) eats only one particular type of bamboo(竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶)will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet(多样化饮食). The bear eats fruits and fish. T
