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 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 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 there germs. For some reason, the way the body fights these mouth germs may end up weakening the heart overtime. _ . Some doctors think that the link between good flossing habits and good heart health is only a coincidence. The incidence of two or more 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. 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. Question: Which is the best title for the passage? Options: A: Flossing by Coincidence B: How to Keep Your Teeth Healthy C: Flossing Habits and Healthy Hearts D: Why Doctors Disagree About Flossing

Article: The interview had been going on for about 20 minutes and everything seems to be going well.Then, suddenly, the interviewer asks an unexpected question, "Which is more important, law or love?" Job applicants in the west increasingly find themselves asked strange questions like this.And the signs are that this is beginning to happen in China. Employers want people skilled, enthusiastic and devoted.So these are the qualities that any reasonably intelligent job applicants will try to show no matter what his or her actual feelings are.In response, employers are increasingly using questions which try and show the applicant's true personality. The question in the first paragraph comes from a test called Kiersey Personality Sorter.It is an attempt to discover how people solve problems, rather than what they know.This is often called aptitude testing. According to Mark Baldwin of Alliance many job applicants in China are finding this type of questions difficult. When a Chinese person fills out an aptitude test he or she will think there is a right answer and they may fail because they try to guess what the examiner wants to see. This is sometimes called the prisoner's dilemma .Applicants are trying to act cleverly in their own interest.But they fail because they don't understand what the interviewer is looking for.Remember that in an aptitude test, the correct answer is always the honest answer. Question: The writer wrote the passage to _ . Options: A: give you a piece of advice on a job interview. B: tell you how to meet a job interviewer C: describe the aptitude test. D: advice you how to find a job

Article: In meditation ,people sit quietly and focus their attention on their breath .As they breathe in and out ,they attend to their feelings .As thoughts go through their minds. They let _ go. Breathe .Let go .Breathe .Let go . According to a recent study at the Insight Meditation Society in Barre,Massachusetts. Three months of training in this kind of meditation causes a market change in how the brain allocates attention. It appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things and events in the outside world. Expert mediators are better than other people at catching such fast-changing stimuli( ),like facial expressions. The study provides evidence for changes in the workings of the brain with mental training. People can learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-being. In an experiment, 17 volunteers with no meditation experience in the experimental group spent three months meditating 10 to 12 hours a day .A control group also with no meditation experience meditated for 20 minutes a day over the same period .Both groups were then given the tests with two numbers in a group of letters. As both group looked for the numbers , their brain activity was recorded. Everyone could catch the first number .But the brain recordings showed that the less experienced mediators tended to grasp the first number and hang onto it, so they missed the second number .Those with more experience gave less attention to the first number .as if letting it go ,which led to an increased ability to grasp the second number ,This shows that attention can change with practice. Just ask Daniel Levision , who meditated for three months as part of the study ."I am a much better listener," he said . " I do not get lost in my own personal reaction to what people are saying." Question: The study proves that _ . Options: A: meditation improves one's health B: brain activity can be recorded C: human attention can be trained D: mediators have a good sense of hearing
