This is because food attracts germs。 germs produce acid, and acid hurts your teeth and gums. Flossing (使用牙線) 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 also be good for your heart. It may seem strange that something you do for your teeth can have any effect on your heart. Doctors have e 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 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 there germs. For some reason, the way the body fights these mouth germs may end up weakening the heart overtime. 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. The incidence (發(fā)生率) of two or more events is pletely 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. Similarly, some doctors think that people who have bad flossing habits just happen to also have heart problems, and people who have good flossing habits just happen to have healthy hearts. 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 true to help your teeth. This is enough of a reason for everyone to floss their teeth every day.（1）From the passage, we know that ________.A.food stuck between your teeth may hurt your teethB.all of the doctors agree that flossing is good for your heartC.doctors39。 judgment about flossing is based on medical researchD.not every doctor thinks flossing helps to keep your teeth healthy（2）The underlined sentence in Paragraph 3 is to ________.A.provide an exampleB.make a parisonC.introduce a new topicD.develop the previous statement（3）Which of the following best states the main idea of the last paragraph?A.It is a fact that flossing can help your heart as well as your teeth.B.There is no good reason to believe that flossing will help your heart.C.Because doctors find flossing won39。t help your heart, it is useless to floss.D.Even if flossing is only good for your teeth, you should still do it every day.（4）Which is the best title for the passage?A.Flossing by CoincidenceB.How to Keep Your Teeth HealthyC.Flossing Habits and Healthy HeartsD.Why Doctors Disagree About Flossing【答案】 （1）A（2）D（3）D（4）C 【解析】【分析】本文提到經(jīng)過研究，剔牙與保持心臟之間沒有必然的聯(lián)系，但剔牙能保護(hù)牙齒的健康是可以肯定的。( 1 )推理判斷題。根據(jù)第一段提到It is bad to have food stuck between your teeth for long periods of time.

We had heard in school about a planet called Pluto. It was the farthest, coldest, and darkest thing a child could imagine. We guessed how long it would take to die if we stood on the surface of such a frozen place wearing only the clothes we had on. We tried to figure out how much colder Pluto was than Antarctica, or than the coldest day we had ever experienced in Pennsylvania. Pluto, which famously was downgraded from a “major planet” to a “dwarf planet”（矮星） in 2006, captured our imagination because it was a mystery that could plete our picture of what it was like at the most remote corners of our solar system. Pluto39。s underdog discovery story is part of what makes it so attractive. Clyde Tombaugh was a Kansas farm boy who built telescopes out of spare auto parts, old farm equipment and selfground lenses.
