Oldest , Youngest , or in the Middle ?

Were you the first or last child in your family? Or were you a middle or the only child? Some people think it matters where you were born in your family. But there are different ideas about what birth order means.

Some people say that oldest children are smart and strong-willed. They are very likely to be successful. The reason for this is simple. Parents have a lot of time for their first child. They give him or her a lot of attention. So this child is very likely to do well. An only child will succeed for the same reasons.

What happens to the other children in a family? Middle children don’t get so much attention. So they don’t feel that important. If a family has many children, the middle ones sometimes get lost in the crowd. The youngest child, though, often gets special treatment. He or she is the “baby”. Often this child grows up to be funny and charming.

Do you believe these ideas about birth order? A recent study saw things quite differently. This study found that the first children believed in family rules. They didn’t take many chances in their lives. They usually followed their own ideas . They took chances. And they often did better in life.

Which theory about birth order do you believe? Look at your own family or you friends’ families. Decide which idea fits what you see.

Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.
