　　According to scientists’ research, the month in which babies are born could affect them in some ways.

　　Babies born in spring get sick easily. Children born under Aquarius (Jan. 21st—Feb. 19th) may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn. Scientists believe many of the differences can be explained by the mother’s exposure to sunlight in pregnancy (懷孕).

　　Sunlight helps lead to the production of vitamin D in the body. The lack (缺乏) of vitamin D in the first months of life may have a bad effect on health.

　　Vitamin D is called the “sunshine vitamin”. It has a good effect on health. A study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the US showed that people born in autumn lived about 160 days longer than those born in spring.

　　Professor Russell Foster said the conclusions were surprising and interesting. He added, “These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth.”

　　American high schools have a dropout rate (輟學(xué)率) of up to 50%. There are many reasons for students leaving school:

　　● For two thirds of the dropouts, motivation (動(dòng)力) is the problem. They can’t just work hard enough.

　　● Almost half of them said that they had missed so many classes that they could not follow any more.

　　● Many said that they were not ready well enough in their earlier school.

　　● For a third of them, getting a job is more important than finishing school.

　　High school dropouts have more problems in their future lives. They are more likely to be out of work or live a poor life. There is also a big difference in income (收入) if you compare (比較) high school dropouts with graduates. A study shows Americans with a bachelor’s degree (學(xué)士學(xué)位) get about $50,000, those with a high school diploma about $28,000 and dropouts only about $20,000.

　　Many younger students do not understand the influence of dropping out of school. They often need better teachers, more lessons to get good grades in subjects and more help with learning problems. Some schools in America have changed this situation. Some schools offer evening classes or allow students to come back at a later age.
