A happy family life doesn't happen by chance. It is a result from husband and wife who carefully and diligently create a home where there is love, respect, forgiveness, patience, service and selflessness.

4. If there is patience in the family, anger will be controlled and there will be peace and harmony.
5. Small acts of service in a family make people's hearts glad. Children learn simple acts of service by giving their parents a glass of water, and a couple serve each other by taking care of family members.

People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals(个人;个体), according to a new analysis of nearly 100 international studies.
The studies, most conducted within the past decade, included about three million adults from around the world. The result of these studies by researchers at the National Center for Health Statistics in Maryland, part of the U.S. Centers for Disease Control and Prevention, shows that slightly overweight or obese people were six percent less likely to die from all causes compared to people of normal weight. But the researchers found that seriously obese individuals were still at a 30 percent greater risk of death compared to healthy-weight individuals.
Study lead author Katherine Flegal says she was not surprised that overweight people would not have a higher death risk. “Because we'd actually already read a lot of this literature and realized that death rates for overweight would be at least not higher than normal[weight," she said. “I guess l was a little bit surprised that it was definitely lower. And l was also surprised that the lower rates of obesity didn't seem to differ from normal weight."
But Flegal stresses the difference in death rates appear to be small between normal-weight people and overweight and mildly obese individuals.
The finding by Flegal and colleagues have raised new questions about the reliability(可靠性)of the so-called "body mass index" or BMI, a measurement of body fat as a ratio(比例，比率)of height to weight, that has become popular in recent years among public healthexperts to measure potential health risks.
But Heymsfield warns that individuals should not conclude that it's okay to put on extra kilograms, since being at a healthy weight lowers the risk for heart disease and diabetes.
1.Katherine Flegal feels surprised at the fact that____.
A. obese people have higher death rates
B. slightly obese people have lower death rates
C. obese people tend to die early
D. death rates have nothing to do with body weight

A. It's OK to put on extra weight.
B. It doesn't matter if you are slightly obese.

When I was a kid, my siblings（兄弟姐妹） and I used to have ice cream for dessert.Every day, we would choose which ice cream flavor to have, whether to eat it in a cone or a bowl. Then we would happily wolf down our treat(款待) as fast as we could.
Once, though, when I was probably about 10 0r 11, our grandpa came to visit. Grandpa always had a unique view on things. On this particular occasion, my sister and I were making bets as to who could finish their ice cream first. With a smile, Grandpa said, "Why would you want to finish first? If you eat slowly, it will last longer. You should have acompetition to see who can finish last." Even now, I always try to taste my ice cream, but of course this is about more than just dessert.
Too often, kids want to scramble（争夺） for more, whether it's more ice cream, more toys, or more friends. This habit persists into our adult years, and we end up constantly scrambling for more. We never develop the skill of appreciating what we have. If we learn to recognize this pattern and change it, we can raise our kids a little differently, giving them the tool of tasting their proverbial dessert, which could lead to a happier life for them.
What my grandpa taught me that day was really that if you take the opportunity to enjoy what's in front of you, the pleasure will last longer and be more rewarding than if you rush through life always trying to get the next treat. It's a lesson that, I think, has made my adult life happier, as well. These days, when I want something, I wait as long as I can before I allow myself to have it. Then, when I finally get it, I make sure to treasure it as long as possible, because I know that, no matter what it is, it will be gone all too soon.
