It is bad to have food stuck between your teeth for long periods of time. This is because food attracts germs(细菌), germs produce acid, and acid hurts your teeth and gums. Flossing(使用牙线) 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 your 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 fight 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. The incidence(发生率) 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 sure to help your teeth. This is enough of a reason for everyone to floss their teeth every day. From the passage, we know that_____
| A．food stuck between your teeth may hurt your teeth |

I don’t often lose things and I’m always careful with money, so I was quite surprised when I reached for my wallet and it wasn’t there. At first, I thought it was possible that I could have left it at home. Then I remembered taking it out to pay the taxi, so I knew I had it with me just before I walked into the restaurant. I wondered if it was possible that it could have dropped out of my pocket while I was eating dinner. I turned and walked back to the table where I had been sitting. Unluckily, there were several people sitting at the table at that time, so I had the waiter go over to the table to see if my wallet was on the floor. While the waiter was looking for it, the head of the restaurant came up to me and asked me if anything was wrong. I told him what had happened. He asked me to report the missing wallet to the police. I told him I didn’t want to do so; I was in a hurry because I had to reach my waiting room before two o’clock, where some people were waiting to see me.

There are good Santas and there are bad Santas. The good Santas all realize one thing: In the mind of a child, Santa Claus is perfect.
That’s difficult. And so they come from around the world to attend the Charles W. Howard School in Midland, Mich. The school offers a three-day, 40-hour course for Santas hoping to be excellent. A former Macy’s Santa named Charles Howard founded the Michigan school in 1937. “Many people will think if you have a suit and you’re a Santa,” said Tom Valent, the school’s current dean. “It’s more than that.”
The school teaches everything from breathing techniques for carol singing to the beard maintenance. There are lessons in child psychology, sign language and even media training for talk-show appearances and call-in shows. Santas also need to make sure they know all the names of the reindeer(驯鹿). What’s harder to deal with, however, is children who ask for Christmas gifts like bringing daddy home or making mommy happy again.
After spending time in the classroom, Weir went to the mall to test his training. However, at one point, his hat fell off, and he was unsure how to react. “You’re the real Santa,” Valent said. “Pick that hat up, slip it back on, keep smiling and do your job. You’ve got to stay on top of your game. Even the last one at night, when you’re tired, you’ve got to remember: This one’s forever, so do a good job.”According to the passage, good Santas should be the ones that ______.
| A．can offer the children some gifts |
| B．help adults look after their children |
| C．have ability to make children happy |
| D．should be perfect in the mind of children |
The Michigan school was founded by Charles Howard with the purpose to ______.
| A．train the pet reindeer for the Santas |
| B．earned money from its students |
| C．train perfect Santas for the world |
| D．show the world’s concern to the poor |
According to Weir’s performance, we can conclude that ______.
| A．Weir was short of experience |
| B．Weir was not fit for the job as a Santa |
| C．Weir did very badly in the game |
| D．Weir was not a good student in school |
People say teenagers are no good. They make too much noise in shopping malls; they drive carelessly up and down America’s main streets. And at least some of the time those things are true. But we shouldn’t forget that there are hard moments in the life of a teenager too.
I watched such a moment not long ago at a woman’s funeral which happened in a church. A teenage grandson stepped forward. Softly he began:“ I want to share a few values that Nana taught me. She never failed to see light in any situation. When our family dog would attack her, what would Nana say? ‘Oh, what beautiful markings that dog has.’ That was Nana.
“She was a strong woman who often lived in the shadow of my grandpa, who was a successful businessman in this city. But she was the one behind the scenes who provided the strength and support for Grandpa’s career,” he said, with a voice now trembling. “That was Nana’s way.”
Finally, in a voice breaking free of sorrow, he looked up and said, “Nana taught me courage. She put up a fight to the end, when she died peacefully, which is how she lived her life. That was Nana’s way, and I hope I can carry on in the same manner.”
There are no hearts as sensitive as those of teenagers, because everything is happening to them for the first time. The trouble with teenagers is that they haven’t learned to be controlled. When that boy rose to speak about the woman who had been his dearest friend, his honest voice dragged each of us out into the open where we could no longer hide. I was moved and learned a lot.According to the first paragraph, ______.
| A．young people are living a hard life |
| B．people don’t think highly of the teenagers |
| C．people shouldn’t forget the young people |
| D．young people should keep quiet before the public |
From the boy’s speech, we know his grandmother ______.
| A．was a weak woman living in the shadow of his grandpa |
| B．liked dogs very much even if they often attacked her |
| C．could see everything around her though she was old |
| D．had great influence over the boy when she was alive |
We can infer from the passage that the boy ______.
| A．was filled with sadness and gave up finishing his talk |
| B．was always very good at expressing himself |
| C．practiced a lot in order to give a moving speech |
| D．had great difficulty in accepting the loss of Nana |
The writer wanted to tell the readers ______.
| A．the young people were too weak to face certain facts |
| B．the young people have learned to control themselves |
| C．the adults could learn something valuable from the young |
| D．the adults should teach the young how to deal with the death |
