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.

Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available soon. The British pany Malloy Aeronautics has developed a prototype (原型) of its flying bicycle. Grant Stapleton, marketing sales director of Malloy Aeronautics, says the Hoverbike is able to get in and out of small spaces very quickly. It can be moved across continents very quickly because it can be folded and packed, he adds. Mr. Stapleton says safety was the pany39。s main concern. He says the designers solved the safety issue by using overlapping rotors to power the vehicle. The pany is testing a fullsize prototype of the Hoverbike, which will most likely be used first by the police and emergency rescue teams. In New Zealand, Martin Aircraft Company is also testing a fullsize prototype of its personal flying device, called the Jetpack. It can fly for more than 30 minutes, up to 1, 000 meters high and reach a speed of 74 kilometers per hour. Peter Coker is the CEO of Martin Aircraft Company. He said the Jetpack is built around safety from the start. In his words, Reliability is the most important element of it. We have safety built into the actual structure itself, very similar to a Formula One racing car. The Jetpack uses a gasolinepowered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute that would be used, if there should be an emergency. It starts to work at very low altitude and actually saves both the aircraft and the pilot, he adds. Mr. Coker says the Jetpack will be ready for sale soon.（1）We can learn from the passage that the Hoverbike ________. A.can hardly get in and out of small spaces quicklyB.can fly for over 30 minutes,
