Before winter arrives, many kinds of birds know that it is time to fly south. The migration (迁徙) has always made us think hard. Why do only some birds migrate? How do birds know when to go south? How do they find their way?
Some birds fly south because their food supply runs short in winter. The woodpecker (啄木鸟), for example, doesn't need to fly south because it can find food in the bark (树皮) of trees. Some birds eat grains, insects and other food that disappear in winter, so they must fly south where food can still be found. But why don't they stay in the south? Perhaps they know that if they stayed down south, they would run out of food there, too.
It is possible that birds know when winter is coming because they find that the days are getting shorter. Once they leave from the north, they use the sun as a compass. The sun is in different positions in the sky at different times of day. To use it as a guide, birds would have to know the time of day. On long flight, most birds use the stars to navigate (导航) their way.
The homing pigeon (信鸽) doesn't use the sun or the stars. Scientists believe that it uses the magnetic field (磁场) of the earth. One of the most amazing migrations is that of the tiny hummingbird (蜂鸟). It travels from Canada to Mexico—a long distance of over 3,600 kilometers.

为什么我们不一样
Have you ever wondered why you are the way you are? What makes you different from your brothers and sisters?
People have asked these questions for centuries, and researchers are trying to answer them. One idea they're thinking is that birth order influences the person we become. In general, the oldest child is described as confident, organized, responsible, and determined(有决心的)to get what he or she wants. Oldest children are seen as born leaders. Because they're the oldest, their younger brothers and sisters sometimes see them as bossy (专横的), or too willing to tell other people what to do.
The middle child may be described as being competitive in order to get more attention. They sometimes feel that their family give them less attention because they are in the middle. Because middle children tend to avoid conflict(冲突), they can be friendly and easygoing. They are usually more influenced by their friends than by their family, perhaps because they get more attention from their friends.
The youngest child is described as the baby of the family. They can be spoiled(宠爱) by their parents, who spend a lot of time with them and often give them what they want. Youngest children enjoy being the center of attention, and they are seen as outgoing, openminded, and likely to take risks.
What if you're an only child? Many people think that a child with no brothers or sisters grows up wanting lots of attention. Some think they're selfish, or unwilling to share with others.
