Advances in health， education and disease prevention and treatments are making human life longer. But what you may not know is that some seemingly unimportant things can also influence how long and how well youll live. Here is the latest research on longevity（长寿）signs.

Sign 1： Your Mom Had You Young

If she was under age 25， youre twice as likely to live to 100 as someone born to an older mom. They think that younger moms produce healthier babies.

Sign 2： Youre a Tea Lover

Both green tea and black tea contain catechins（儿茶酚）， something that helps blood vessels（血管）relax and protects your heart. In a study of more than 40，500 Japanese men and women， those who drank five or more cups of green tea every day had the lowest risk of death from heart disease. Other studies about black tea showed similar results. You really need only one or two cups of tea daily to start doing your heart some good. Ready-to-drink tea doesnt offer the same health effects. “Once water is added to tea leaves， their catechins disappear within a few days，” says a professor. Also， some studies show that adding milk may get rid of teas effects， so stick to just lemon or honey.

Sign 3： Youd Rather Walk

“Fit” people—defined as those who walk for about 30 minutes a day—are more likely to live longer than those who walk less. So take a walk during your lunch hour， do exercise around the field while your kid is at soccer practice—try by hook or by crook to move a little more， every day.

Sign 4： You Have Strong Legs

Lower-body strength translates into good balance， flexibility， and power， which， as you get older， play an important part in reducing your risk of falls and injuries， leading to better health. Now you see， it is necessary to strengthen your lower-body. But the question is： how？

Itake the position that parents do not owe their children a college education. If they can afford it， they can certainly send them to the best universities. But they must not feel guilty if they cant. If the children really want to go， theyll find a way. There are plenty of loans（贷款）and scholarships for the bright and eager ones who cant afford to pay.

When children grow up and want to get married， their parents do not owe them a down payment on a house. They do not have the duty to look after their grandchildren. If they want to do it， it must be considered a favor， not an obligation.

Do parents owe their children anything？ Yes， they owe them a great deal.

One of their obligations is to give their children a personal worth. A child who is always made to feel stupid and unworthy， constantly compared with brighter brothers， sisters， or cousins will become so unsure， so afraid of failing that he （or she） wont try at all. Of course they should be properly corrected when they do wrong， but its often better to let children learn their mistakes by themselves in time. All their parents should do is to trust them， respect them， understand them and give them chances to try and fail. They must learn to stand failure. When criticisms are really needed， they should be balanced with a smile and a kiss. That is the way children learn.

Parents owe their children a set of solid values around which to build their lives. This means teaching them to respect the rights and opinions of others； it means being respectful to elders， to teachers， and to the law. The best way to teach such values is by deed（行为）. A child who is lied to will lie. A child who sees no laughter and no love in the home will have difficulty laughing and loving.

No child asks to be born. If you bring a life into the world， you owe the child something.

5. We can learn from Paragraph 1 that parents ___ .

A. must support their children even after they get married

B. should make a down payment on a house for their children

C. should take loans to send their children to go to college

D. neednt feel guilty if they cant send their children to universities

6. What does the underlined word “obligation” in Paragraph 2 mean？

A. Duty. B. Loan.

C. Right. D. Excuse.

7. What should parents do when children make mistakes according to the author？

A. Understand them and tell them not to do that again.

B. Let them learn the mistakes by themselves in time.

C. Compare them with brighter brothers or sisters.

D. Correct their mistakes immediately.

8. What does the author mainly talk about in this passage？

A. The duties of the parents.

B. The best way to teach children.

C. The reason why children feel stupid and unworthy.

D. The reason why parents owe their children something.
