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 |
| B．all of the doctors agree that flossing is good for your heart |

The professor stood before his class of 30 senior biology students, about to pass out the final exam. “I have been honored to be your instructor this term, and I know how hard you have all worked to prepare for this test. I also know most of you are off to medical school or graduate school next fall,” he said to them.
“I can well understand how much pressure you are under to keep your grades up, and because I know you are able to understand this material, I am prepared to offer an automatic(自动的) “B” to anyone who would prefer not to take the final.”
In relief a number of students jumped up to thank the professor and left the class. The professor looked at the students who remained, and offered again, “Any other takers? This is your last chance.” One more student decided to go.
There were seven students left. The professor closed the door. Then he handed out the final exam. There were only two sentences typed on the paper: “Congratulations, you have just received an “A” in this class. Keep believing in yourself.”
I never had a professor who gave a test like that. It may seem like the easy way out of grading (评分) a lot of exams, but it’s a test that any teacher in any subject could and should give. Students who don’t have confidence in what they’ve learned are “B” students at best.
The same is true for students of real life. The “A” students are those who believe in what they’re doing because they’ve learned from both successes and failures. They have learned life’s lessons, whether from formal education or the school of hard knocks, and become better people.
Take your cue(榜样) from Sir Edmund Hillary, the first person to reach the top of Mount Qomolangma: “It’s not the mountain we conquer (征服), but ourselves.” Don’t let the biggest limit be yourself.
53. The professor offered an automatic “B” to those who would prefer not to take the final exam because _________.
A. he liked the students who wanted to get a “B”
B. he believed they were able to pass the exam
C. he thought any teacher should give them a “B”
D. he thought it was the easy way of grading exams
54. According to the text, which of the following statements is TRUE?
A. 22 students got a “B” in the final test without doing the paper.
B. Most of the students would go to medical school shortly after the exam.
C. There were actually no problems on the test papers for the students to work out.
D. The way the professor tested his students would not be suitable for other subjects.
55. According to the writer, the test given by the professor was ________.
A. funny B. meaningful C. difficult D. harmful
56. The point of the story is to advise readers _________.

A frightening example of the sea’s power saw 125,000 people die in 12 different countries last week. The terrible disaster was caused when a great earthquake sent tsunamis breaking into Indian Ocean coastlines. Various areas in Sri Lanka, Indonesia, Thailand, India, Malaysia and East Africa have been destroyed by the huge waves. Whole towns were simply swept aside by the power of the water. Cars, trains and buildings could not remain steady, not to say the people who stood in the way.
The earthquake measured 9.0 on the Richter scale and occurred off the coast of Indonesia. It was recorded as the fifth strongest since 1900. Scientists said the quake was as powerful as a million of the atomic bombs that were dropped on Japan during the World War II. “This may be the worst natural disaster in recent history because it is affecting so many heavily populated coastal areas.” said Jan Ege-land, a UN official.
Because such waves hardly happen in the Indian Ocean, there is no system in place to warn coastal people who are about to be hit. Tsunami is a Japanese word. They are usually caused by a sudden rise or fall of part of the Earth’s crust under the ocean. Tsunamis often happen in oceans and they are most common in the Pacific.
Tsunamis can be very long, as much as 100 kilometers. They are able to cross entire oceans without losing much energy. One of the most striking facts about tsunamis is that an earthquake on one side of the Pacific Ocean can cause huge waves on the other side.
When the ocean is deep, tsunamis can travel unnoticed at speeds of up to 800 kilometers per hour. They can cross the entire ocean in a day or less. The wave may only be a few meters high in the ocean, but when it is near the shore and reaches shallow water, the wave builds up very quickly in height.
61. How many countries were stricken by the terrible disaster?
A. 6. B. 12. C. 18. D. Not sure.
62. All of the following statements are true EXCEPT __________.
Tsunami is a word taken in from Japanese
Tsunamis are quite common in the Indian Ocean
The earthquake measured 9.0 on the Richter scale
No warning system has been set up to watch tsunamis there
63. We can know from this passage that __________.
the earthquake has been the strongest in the last century
the wave soon becomes higher when it reaches the shore
the atomic bombs were more powerful than the earthquake
tsunamis can cross entire oceans with almost the same energy
64. You’ll see the passage in __________ section of a newspaper most probably.
A. Sports B. Health C. News D. Culture
In 2007, the first solar electric boat crossed the Atlantic Ocean. Now a Swiss group wants to cover that distance and keep going, circling the globe on nothing but the sun’s power for the first time.
The team of engineers and scientists has started the building of its 98-foot long boat, named Planet Solar, in Kiel Germany. The boat’s power will come from the 5,000 square feet of solar panels（电池板）, about the size of two tennis courts, covering its broad deck. When the sun is shining bright above, they will turn 23 percent of the sun’s rays to energy — six percent more than average solar panels.
Even though batteries aboard Planet Solar can store enough energy to power it through up to three days of cloudy weather, the sailors will try to avoid clouds: constant communication with the French meteorological institute, Meteo France, will help the sailors stay with the sunny course.
The $11.5 million project, which is led by Raphael Domjan, should be ready for its first voyage next summer. The solar electric boat will warm up in European waters, and attempt to deal with traveling around the globe in spring 2011. At a maximum speed of 16 mph, Planet Solar will be the fastest solar electric boat. The team expects to finish the first leg of its journey across the Atlantic in about two weeks, compared to the six months the solar boat took back in 2007.
If sailing by sun becomes practical, it would be a return to the green boating methods of the days of Christopher Columbus. Those long-ago voyages relied only on a different type of renewable energy: wind. And, if wind-powered sails could be combined with solar panels, we might really pick up the boating speed.
57. Which of the following is NOT true about Planet Solar?
A. Its deck is covered by solar panels.
B. It will be the fastest solar electric boat.
C. It is 98-foot long and is to be made in Germany.
D. It can turn 17 percent of the sun’s rays into energy.
58. Planet Solar will be likely to __________ in continuous rainy weather.
A. continue traveling forward
B. ask the local weather station for help
C. stop to wait for the weather to clear up
D. turn to Meteo France for help to choose the sunny course
59. What can be inferred from the passage?
A. Sailing by solar energy has not been widely used in today’s green boating.
B. Planet Solar will be the first boat to circle the globe using solar energy in 2011.
C. The solar panels in Planet Solar can turn more sunlight to energy than average ones.
D. Batteries aboard Planet Solar can be consumed for at most three days of cloudy weather.
60. What is the main idea of the passage?
A. Planet Solar uses solar energy all over the world.
B. Planet Solar aims to be the first to circle the globe.
C. Planet Solar collects a different kind of renewable energy.
D. Planet Solar combines traditional methods with modern technology.
