It is bad to have food stuck between your teeth for long periods of time. This is because food attracts germs, germs produce acid, and acid hurts your teeth and gums. Flossing helps to remove the food that gets stuck between your teeth. This explains why flossing helps to keep your mouth healthy,but some doctors say that flossing can be also good for your heart.
It may seem strange that something you do for your teeth can have any effect on your heart.
Doctors have come up with a few ideas about how flossing works to keep your heart healthy. One idea is that the germs that hurt your teeth can leave the mouth and travel into your blood. Germs that get into the blood can then attack your heart. Another idea is based on the fact that when there are too many germs in your mouth, the body tries to fight against these germs. For some reason, the way the body fights these mouth germs may end up weakening the heart over time.
Not every doctor agrees about these ideas. Some doctors think that the link between good flossing habits and good heart health is only a coincidence. A coincidence is the occurrence of two or more events at one time apparently by mere chance. The incidence of these events is completely random, as they do not admit of any reliable cause and effect relationship between them. For example, every time I wash my car,it rains. This does not mean that when I wash my car,I somehow change the weather.
This is only a coincidence.
The theory that flossing your teeth helps to keep your heart healthy might not be true. But every doctor agrees that flossing is a great way to keep your teeth healthy. So even if flossing does not help your heart,it is sure to help your teeth. This is enough of a reason for everyone to floss their teeth every day.
Flossing effectively helps to keep your mouth healthy by preventing________.
A.germs from producing acid
B.food from entering your body
C.germs from entering into your blood
D.acid from contacting your teeth and gums

Years ago, a cigarette commercial asked if you were smoking more, but enjoying it less. That describes the way many of us live today. We are doing more, but enjoying it less. And when that doesn't work, we compound the problem. In our frantic search for satisfaction, we try stuffing still more into our days, never realizing that we are taking the wrong approach.
The truth is simple; so simple it is hard to believe. Satisfaction lies with less, not with more. Yet, we pursue the myth that this thing, or that activity, will somehow provide the satisfaction we so desperately seek.
Arthur Lindman, in his devastating book, The Harried Leisure Class, described the futility of pursuing more. His research focused on what people did with their leisure time. He found that as income rose, people bought more things to occupy their leisure time. But, ironically, the more things they bought, the less they valued any one of them. Carried to an extreme, he predicted massive boredom in the midst of tremendous variety. That was more than twenty years ago, and his prediction seems more accurate every year.
Lindman of course, is not the first to discover this. The writer of Ecclesiastes expressed the same thought thousands of years ago. It is better, he wrote, to have less, but enjoy it more.
If you would like to enjoy life more, I challenge you to experiment with me. How could you simplify your life? What could you drop? What could you do without? What could you stop pursuing?
What few things could you concentrate on?
The more I learn, the more I realize that fullness of life does not depend on things. The more I give up, the more I seem to gain. But words will never convince you. You must try it for yourself.
Arthur Lindman wrote________.
A.a novel
B.The Harried Leisure Class
C.Ecclesiastes
D.an article on smoke
