Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help.
First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling (腫大) and pain may occur. Unless the burn involves large portions of the body, it can be treated at home.
Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters (水泡) develop. Severe pain and swelling also occur. Second-degree burns require medical treatment.
Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention.
Follow these steps when treating minor burns at home:
1) If the skin is not broken, run cool water over the burn for several minutes.
2) Cover the burn with a sterile (消過(guò)毒的) bandage or clean cloth.
3) Take aspirin to relieve any swelling or pain.
Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps:
1) Remove the person from the source of the burn (fire, electrical current, etc.).
2) If the person is not breathing, begin mouth-to-mouth resuscitation (人工呼吸) immediately.
3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it.
4) Cover the burned area with a cool, moist, sterile bandage or clean cloth. Do not place any creams, ointments (藥膏) or ice on the burned area or break blisters.
5) Monitor the patient for signs of shock, and treat accordingly.

We can make mistakes at any age.Some mistakes we make are about money.But most mistakes are about people.One might say, "Did Jerry really care when I broke up with Helen?" "When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?" When we look back, doubts like these can make us feel bad.
Why do we go wrong about our friends? Sometimes what people want to say hides their real meaning.And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, "You're a lucky dog." Is he really on your side? If he says, "You are a lucky guy", that's being friendly.But if he says "a lucky dog", there's a bit of envy in those words.Maybe he doesn't see it himself.But he puts you down a little if he brings in the "dog".What he may be saying is that he doesn't think you deserve your luck.
"Just think of all the things you have to be thankful for" is another noise that says one thing and means another.It could mean that the speaker is trying to get you to see your problem as part of your life as a whole.But is he trying to? Wrapped up in this phrase is the thought that your problem isn't important.It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.
How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking.Do his words fit the way he looks? Does what he says agree with the tone of voice, his posture, or the look in his eyes? Stop and think.The minute you spend thinking about the real meaning of what people say to you may save another mistake.
Therefore, when you hear someone saying, please try to know what he really means.Don't just listen to what he says with your ears but feel the words he uses with your head.In this way you may make fewer mistakes.

.In the 1st paragraph, the writer says something that happened between him and his friends ____.

When it comes to eating out, we can't help thinking of big meals in the restaurants, which usually contain much more fat and less fibers. Whether it is a business meeting over lunch or a fast food meal with the kids, eating out is a part of our lives. We eat out to save a lot of time, like grabbing a bite at fast food restaurants, or we take dining out as a favorite way to relax and socialize with friends.
Eating out can be fun but many people still like eating at home more because it is healthier. When my dear wife does not prepare foods for me, I would rather cook some instant noodles and eat at home! However, we go out to eat once in a while for holidays or on special occasions.
More and more people want to make healthy food choices nowadays. Some are watching calories, while others want to keep their cholesterol(膽固醇)under control or eat less fat. Plan ahead and choose wisely, you will find foods that fit into your meal plan and make eating out both healthy and enjoyable.
Here are some pointers to remember that can help you make wise choices when eating out: go for balance, watch portion sizes and drink water or low-fat milk. Keep the ground rules of good nutrition in mind. Eat a variety of foods in moderate(適中的)amounts, limit the amount of fat you eat, and watch the amount of salt in food. If you develop the skills to make healthy choices now, your body will thank you later.
Eating out can be one of life's great pleasures. Make the right choices, ask for what you need, and balance your meals out with healthy meals at home. You can enjoy yourself and take good care of yourself at the same time.

科目:高中英語(yǔ) 來(lái)源:不詳 題型:閱讀理解

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “l(fā)imitless” and could “l(fā)ast forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
  Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.
  For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水區(qū)) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方體的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.
小題1:The author’s attitude towards the use of natural resources is _________.
A.positiveB.uninterestedC.optimisticD.critical
小題2:According to the author, the greatest mistake of our forefathers was that _________.
A.they had no idea about scientific forestry
B.they had little or no sense of environmental protection
C.they were not aware of the importance of nature study
D.they had no idea of how to make good use of raw materials
小題3:To avoid repeating the mistakes of our forefathers, the author suggests that _________.
A.we plant more trees
B.natural sciences be taught to everybody
C.environmental education be directed toward everyone
D.we return to nature
小題4:How can you understand the underlined sentence in the last paragraph?
A.Our living space on the earth is getting smaller and smaller.
B.Our living space should be measured in cubic volume.
C.We need to take some measures to protect space.
D.We must preserve good living conditions for both birds and animals.

There is a boy called Bill in my gym class who has unbearably yellow teeth that almost make everyone feel unpleasant.Recently another boy told Bill that he should "go Ajax" his teeth.Bill was crushed.If the other boy had been thinking, he would have realized that there is a better way to handle such a situation.He could have dealt with it with tact.He could have showed this hurtful truth in a more careful, sensitive way—that's "tact".
If a person isn't sensitive to another's feelings, there is no way he or she can be tactful.Yesterday, my 5-year-old brother proudly announced that he had cleaned the screen on our television set.Unfortunately, he used furniture polish, which produced an oily film on the television screen.My mother smiled arid thanked him for his efforts—and then showed how to clean the screen properly.Her sensitivity enables my brother to keep his self-respect.Yet, sensitivity alone does not make tact.
"Tactfulness" also requires "truthfulness".Doctors, for example must be truthful.If a patient has just been disabled in an accident, a tactful doctor will tell the truth—but express it with sensitivity.The doctor may try to give the patient hope by telling them curing techniques under study or about advanced equipment now available.Doctors must use tact with patients' relatives as well.Instead of bluntly saying, "Your husband is disabled," a doctor might say, "I'm sorry, but your husband has lost feeling in his legs and..."
Tact should not be confused with trickery.Trickery occurs when a nurse is about to give a patient an injection(注射) and says, "This won't hurt a bit." Instead of trickery, the nurse might guarantee the patient that the discomfort of the injection is a small thing compared to the benefits of it.It would also be thoughtful for the nurse to tell the patients about some of these benefits.
Tact is a wonderful skill to have, and tactful people are usually admired and respected.Without tact our society would become an intolerable place to live in.
小題1:The underlined word "crushed" in the first paragraph probably means____.
A.surprisedB.cheatedC.regretfulD.painful
小題2:According to the author, his mother's praise for the brother is ____.
A.sensitive and tactfulB.sensitive but not tactful enough
C.truthful but not tactful enoughD.sensitive but trickish

Goats are being hired to do the work of people near SanDiego. The fires that occurred in Hillborbough four years ago destroyed thirty homes, most of which have been rebuilt. While people were rebuilding the homes, the grasses and bushes were growing back. The area is now so overgrown in bushes that there is again a major danger of fire.
The city council asked for offers to remove the bushes. The lowest bid they received was $50,000-----and that was if the city provided breakfast and lunch for the workers for thr six weeks it would take to clear the overgrown area. The city only wanted to give unlimited coffee and a piece of bread a day for each person. When that offer was rejected, the city asked for help on its website.
A sheepherder(養(yǎng)綿羊的人) in Montanta and a goatherder(養(yǎng)山羊的人) in San Bernardino read about the city’s plight (困境)while surfing the Web on their laptops. They both offered to do the job for $25,000. The council chosed the goatherder because he lived closer. When he was told that the city dump(垃圾場(chǎng)) was overflowing , the gotherder said, “No problem. My goats will eat everything in your dump, except the car engines, of course.” So ,for another $5,000, the city killed two birds with one stone. If all goes well, they will invite the goatherder and his “family” back every three years. The goatherder said that he would probably visit San Diego while his goats were in the dump. “I want to go there by plane, I just hope we don’t crash. My goats will miss me a lot.” He said.
小題1:Why did the city council want to remove the bush?

小題2:The goatherder was chosen to do the job because       
A.He offered to do it for the lower price
B.It was easier to transport his goat

小題3:According to the passage,

B.the lowest bid to remove the bushes was $50,000

Butter is bad for you—so is margarine(人造黃油).Coffee raises blood pressure, but may protect against cancer.Alcohol is okay, but only if it's wine.The confusing studies on what is safe to eat and drink are enough to make it impossible for anyone to understand what "good food" is.
Take the margarine-butter debate for example.Studies that linked fat—found mostly in animal products such as meat and butter—with cancer and heart disease sent millions rushing to buy margarine.But then another study found that people who ate a lot of margarine also had high levels of heart disease.For those who have a firm faith in science, this seems to be the end of the world.
But many doctors point out that their advice has never been conflicting.For years, and in various countries, they have recommended eating less fat.
People in western countries such as Britain and the United States get about 40 percent of their calories from fat.Doctors say this should be around 30 or even 25 percent,
"We must try to reduce total fat," said Dr.Robert Richardson of the University of Edinburgh, who has been studying the effects of fat on human health for years.
"We need to go to more such food as bread, in particular brown bread, and more fruit and vegetables."
Fresh produce may not be so safe, either.Last month the British Government advised consumers to peel their pears before eating, while many Americans briefly avoided apples because of fears over an insect killing chemical.
But Dr.Arnold, a British scientist, said any risk of such poisoning would be outweighed by the costs of not eating plant foods.
"On balance, if you were to put both risks against each other, the advice has to be eating as much fruit and vegetable daily as possible," she said.
In general, doctors conclude, variety truly is the best policy."The general advice is pretty much the same advice that doctors have been talking about for a long time—a varied diet, a mixture of foods and not too much of any one," Arnold said.
小題1:In which section of the magazine are you most likely to find this passage?
A.Arts and CultureB.Entertainment
C.NatureD.Health
小題2:The British Government advised consumers to peel their pears before eating because ________.
A.it found that there were insects on the pears
B.it wanted consumers to avoid insect, killing chemicals
C.the skin of pears was found to be bad for people's health
D.it was a bad habit not to peel them
小題3:The underlined word "outweigh" (Para. 8) means " __________."
A.to be heavier than usual or allowedB.to be more dangerous than
C.to be greater in value or importance thanD.to be considered less important than
小題4:What can we infer from the passage?

B.Science provides answers to all our questions.
C.We should peel our pears before eating.
D.We should eat plant foods despite the risk of poisoning.
