Scientists are making new studies of color and its effects on our health. They have known for a long time that the color of a room or the color of the light in it can affect our feelings and emotions. Many prisons and hospitals have at least one room that is painted pink. Officials have found that light and color can produce physical changes in our bodies.

Professor Falfan worked with a group of 9 disabled children at school in Albert. Two of the children were blind. The other seven had normal sight. The scientists changed the color of the school room, and then looked for changes in blood pressure, heart beat and breathing rate. The effects of color changes were the same for the blind children as for those with normal sight. Their blood pressure dropped from about 120 to 100. Similar changes were reported in heart-beat and the breathing. The children were also calmer and less excited. Then the colors of the room were returned to orange and white. Blood pressure, heart-beat and breathing rate went up and the children became excited again.

Professor Falfan said different colors produce different levels of light energy. He said the differences seem to affect chemicals in the brain that carry messages from nerve to nerve and from nerve to muscle.

1. Light and color can affect　　.

A. only one’s feelings and emotions

B. one’s energy

C. one’s mental changes

D. one’s heart-beat, brain activities, blood pressure, feelings and emotions

2. The color of pink had a calming effect, that is to say, the color affects　　.

A. the chemicals in the brain

Many songs, poems, and books have been written on love’s strong effect on people. The state of being in love has even been compared to being sick or mad. A study by Professor Semir Zeki of University College London has found that love does affect people’s brains by making them feel great.

Zeki studied young men and women who had recently fallen in love. He found that, when they were looking at photos of their loved ones, there was heightened activity in four areas of their brains. These areas deal with emotions, and one of them, in particular, is known to respond to drugs that cause feelings of great joy and excitement.

Interestingly, the study also found a lack of activity in two other areas of the brain when the volunteers looked at their lovers’ photographs. One of these areas is linked to feelings of sadness, while the other is often active in people suffering from depression. It seems love really can be uplifting.

The state of being in love, according to some scientists, may actually be good for your health. Although scientists know that being in love can make a person feel great, the exact influence of love on a person’s health is harder to determine. However, scientists say that people do need love in order to live healthy lives.

According to Dr. Thomas Lewis, people need to be in relationships because that is how we are designed. He says the brain can only maintain(保持) the overall stability of a person’s immune(免疫) system, bodily rhythms, and heart if it receives input(输入) from outside the body in the form of emotional connections with others.

Professor Antonio Damasio has a similar view. He says that love enriches a person’s imagination and creativity, and makes a person’s body work better. He also believes that love can even improve the body’s ability to fight against disease. Damasio’s wise words of advice are “ Choose love and you will live longer.”

1.What is the main idea of this passage ? __________.

A. love can really cause people active

B. love has an effect on songs and books

C. love is linked with emotion

D. love is what we need

2.What does the underlined word “uplifting” mean? It means __________.

A. inspiring　　 B. available　　 C. cold　　 D. mad

3.From the passage we can conclude that__________.

A. People write songs, poems and books to say love is the sweetest thing

B. nobody but Professor Semir Zeki has understood love does affect people’s brains

C. being in love sometimes may make someone act as if he/ she were mad

D. love causes heightened activity in all areas of a person’s brains

4.Which of the following statements is not true?

A. Some scientists have the idea that love does good to people.

B. It is possible for scientists to decide how much influence love can give people.

C. People are born to be in need of getting on touch with each other.

D. A person’s health depends on partly on emotional connections with others.

For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants（污染物）can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.

People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.

As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.

1. Generally speaking, indoor air pollution may be more harmful than the air outside because _　　　　　　　　 .

A．indoor air pollution can often make people seriously ill

B．there may be more harmful gases outside the buildings

C．man-made building materials give off dangerous gases

D．the air indoors is polluted, which is very harmful

2. Some kind of indoor pollution can be found in _______.

A．every old house　　　 B．every modern house

C．all kinds of houses D．all kinds of offices

3. The indoor air pollution is caused by ______.

A．the man-made building materials and the limit of air-flow

B．the building way that the builders want to save energy

C．the building things that are made of man-made materials

D．the limit of the flow of air between inside and outside

4. The reason why we should use different kinds of plants to clean the air is that ______.

A．plants can let out all kinds of pollutants indoors

B．plants may take in more oxygen which people need

C．plants can make our houses prettier and more healthy

D．plants can absorb all kinds of harmful indoor chemicals

Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.

That food is related to illness is not a new discovery. In 1945, about 68 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

1.What is the best possible title of the passage?

A．Drug and Food                         B．Cancer and Health

C．Food and Health                        D．Health and Drug

2.Which of the following statements is NOT true?

A．Drugs are always given to animals for medical reasons

B．Some of the additives in our food are added to the food itself and some are given to the living animals

C．Researchers have known about the potential dangers of food additives for over thirty-five years.

D．Food may cause forty percent of cancer in world.

3.How has science done something harmful to mankind?

A．Because of science, diseases caused by polluted food have been virtually eliminated.

B．It has caused a lack of information concerning the value of food.

C．Because of the application of science, some potentially harmful substances have been added to food.

D．The scientists have preserved the color of meats, but not of vegetables.

4.What are nitrates used for?

A．They preserve flavor in packaged foods.

B．They preserve the color of meats.

C．They are the objects of research.

D．They cause the animals to become fatter.

5.The word 'carcinogenic' most nearly means '_____'.

A．trouble-making     B．color-retaining      C．money-making      D．cancer-causing
