Bad teeth can be painful -- and worse. They can even be deadly. Infections (感染) of the gums (牙龈) and the teeth can cause bacteria (细菌) to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk.

For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿保健) he needed. He was twelve years old.

Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.

But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.

When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.

The use of fluoride (氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (珐琅质) , the hard surface on teeth, to help prevent holes from forming.

NOT all memories are sweet. Some people spend all their lives trying to forget

bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.

Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce ,or possibly erase(抹去),the effect of painful memories.

In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.

The research has caused a great deal of argument. Some think it is a bad idea, while others support it.

Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.

“Some memories can ruin people's lives . They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."

But those who are against the research say that changing memories is very dangerous because memories give us our identity (特质). They also help us all avoid the mistakes of the past.

"All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.

47. The passage is mainly about _________.

A. a new medical invention

B. a new research on the pill

C. a way of erasing painful memories

D. an argument about the research on the pill

48. The drug tested on people can __________.

A. cause the brain to fix memories

B. stop people remembering bad experiences

C. prevent body producing certain chemicals

D. Wipe out the emotional effects of memories

49. We can infer from the passage that ___________.

A. people doubt the effects of the pills

B. the pill will stop people's bad experiences

C. taking the pill will do harm to people's health

D. the pill has probably been produced in America

50. Which of the following does Rebecca Dresser agree with?

A. Some memories can ruin people's lives.

B. People want to get rid of bad memories.

C. Experiencing bad events makes us different from others.

D. The pill will reduce people's sufferings from bad memories.

Working hard for fun

No more pencils! No more books

No more teacher’s serious looks!

After a long period of study and work, the young Americans burst through the school doors singing.

But unfortunately, American students do very poorly and are among the worst students in the world. In the entire field of subjects---from geography and maths to science and general knowledge. American students are the poorest performers. Why? What’s the reason behind the scene? One problem lies in the fact that so little is expected from them. The standards of success are too low. Teachers are not willing to give out low grades and fail students. Besides, the existing negative results are few and mean little to students if their performance in study is poor . Of course some students realize that a high school diploma is a measure of success and will be important to get a job or get admitted into college. But they only have to go through the motions without really trying. They learn to get by with a minimum of effort.

In America, it is simply too easy for high school students to enter college. This forms a sharp contrast with the students in China and other Asian countries who have to suffer heavy pressure from parents, teachers and cruel social facts. Chinese students have to study hard for long years to pass the national college entrance examination which few Americans will take such trouble to enter to university. The majority American students know that they will be able to get into some college, so they do not really worry about it.

It turns out that American high school students are just too busy to find time to study. They spend almost no time on study while students from other countries spend four or five hours per day on homework. American students on the average give less than five hours per week to their studies. Learning and reading for future are not important to them. Many American never read. It is little wonder why Americans knows less than students from other countries.

1. Why are American students the poorest performers in the entire field of subjects?

A. Because they are too busy to find time to study.

B. Because they are too stupid and too lazy.

C. Because they care little about their study.

D. Because so little is required from them

2. Which of the following is Not true ?

A. Most of American students spend less than five hours on their study every week.

B. Few American students have trouble to enter college.

C. American students can be admitted into college even without a high school diploma.

D. It is hard for the students in China to enter college.

3. What seems to be the writer’s attitude towards American students?

A. He probably thinks much should be expected from them.

B. He is in favour of American students’ learning methods.

C. He shows no interest in American students’ study.

D. He thinks American students study hard.

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!

There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green －a strange world indeed.

Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.

Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

1. The passage is mainly about _____________.

A. color and its surprising effects. B. women being luckier than men

C. danger caused by color blindness D. color blindness

2. According to the passage, with the help of the “cones”, we can_______________.

A. tell different shapes B. see in a weak light

C. kill mosquitoes D. tell orange from yellow

3. Why do some people say it is safer to be driven by women?

A. Women are more careful. B. There are fewer color-blind women

C. Women are fonder of driving than men. D. Women are weaker but quicker in thinking.

4. Which of the statements about the color- blind is true?

A. Not all of them have the same problem in recognizing color.

B. None of them can see deep red.

C. None of them can tell the difference between blue and green.

D. All of them see everything in shades of green.

5. We can attract and kill mosquitoes by using a _____________.

A. red light B. yellow light C. blue light D. green light
