B
Most American kids love Halloween treats, but a bucket of Halloween candy can be a dentist’s nightmare. Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need to separate the good kinds of treats from the bad.
It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to pediatric dentist Dr. Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice. Hard candies take a long time to consume and are also a bad choice for Halloween treats
If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies, chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the bacteria in the mouth. But no matter what a child eats, brushing after each meal is still the best way to fight cavities.
55.What is the main purpose of this passage?
A. To discuss how cavities can be treated.
B. To point out the problems with Halloween celebrations.
C. To tell parents what sweets are less damaging to their children’s teeth.
D. To teach parents the meaning of Halloween candies for their children.
56.Why are hard candies especially bad for teeth?
A. They may break the child’s teeth.
B. They contain too much sugar.
C. They help bacteria to produce tannins.
D. They stay in the mouth for a long time.
57.According to the passage, which of the following is a better choice for Halloween treats?
A. Chocolate. B. Crackers. C. raisins. D. Potato chips.
58.According to the passage, which of the following is true of tannins?
A. They are produced when the bacteria digest the food.
B. They help to get rid of some bacteria in the mouth.
C. They help chocolate to dissolve more quickly.
D. They destroy the surface of the teeth.

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(自動(dòng)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 (評(píng)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(榜樣) 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.
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
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.
According to the writer, the test given by the professor was ________.
A. funny | B. meaningful | C. difficult | D. harmful |
The point of the story is to advise readers _________.
A. to pay attention to what they can do
