Experts are finding your standard first aid response may be the worst thing you can do in an emergency.Here’s how to update your first aid kit.
CUTS AND SCRAPES
When the skin isn’t broken，it’s hard to beat iodine (碘酒) for killing bacteria.
doctors use it to clean before surgery.But when there’s a cut，full?strength iodine and rubbing alcohol can be harmful to skin cells，preventing healing.Putting iodine on cuts and wounds kills bacteria，but it won’t clean the wound.The most effective way is washing the wound with water.
BURNS
If you spread some butter on the burn to ease the pain，it isn’t a good idea.Butter was thought to cool the burn，but it can cause infection and create an environment for bacterial growth.Run the burn under cool water immediately to help remove the heat and put an end to the damaging process. Wrap the burn with a bandage，and keep it clean and dry.If blisters (水泡) form，don’t break them.
POISONING
When a child swallows anything poisonous，parents probably think they’re well prepared if ipecac (催吐剂) is on hand.Wrong.Ipecac was thought to be a good way to treat a child who had swallowed a poisonous substance，but not any more because it doesn’t always remove the toxic substance.That may cause dehydration (脱水) and prevent doctors from giving other treatments.
EXCESS BLEEDING
Everyone learns how to stop bleeding with a tourniquet (止血带).But studies show this method causes more harm than good.Tourniquets can increase the risk of tissue damage or even the loss of a limb.Apply direct pressure to the wound.Simply place a clean cloth on the wound and press firmly；don’t remove the cloth，even if it gets black.If necessary，add more cloths.If that’s not enough，you can further slow the blood flow by applying pressure to the main artery (动脉) of the upper arm or leg.

People living on parts of the south coast of England face a serious problem. In 1933, the owners of a large hotel and of several houses discovered, to their surprise that their gardens had disappeared overnight. The sea had eaten into the soft limestone cliff (悬崖) on which they had been built. While ex??perts were studying the problem, the hotel and several houses disappeared altogether, sliding down the cliff and into the sea.
Erosion (侵蚀) of the white cliffs along the south coast of England has always been a problem but it has become more serious in recent years. Dozens of homes have had to be aban??doned as the sea has crept farther and farther inland. Experts have studied the areas most affected and have drawn up a map for local people, forecasting the year in which their homes will be eaten up by the hungry sea.
Angry owners have called on the Government to erect sea defenses to protect their homes. Government surveyors have pointed out that in most cases, this is impossible. New sea walls would cost hundreds of millions of pounds and would merely make the waves and currents further along the coast, shifting the problem from one area to another. The danger is likely to continue, they say, until the waves reach an inland ar??ea of hard rock, which will not be eaten as limestone is. Mean??while, if you want to buy a cheap house with an uncertain fu??ture, apply to a house agent in one of the threatened areas on the south coast of England. You can get a house for a knock??down price but it may turn out to be a knockdown home.
What is the cause of the problem that people living on parts of the south coast of England face?
A. The rising of the sea level.
B. The experts’ short of knowledge.
C. The washing-away of limestone cliff.
D. The disappearance of hotels, houses and gardens.
The erosion of the white cliffs in the south of England ________.
A. will soon become a problem for people living in central England
B. has now become a threat to the local residents
C. can be stopped if proper measures are taken
D. is quickly changing the map of England
The experts’ study on the problem of erosion can ________.
A. warn people whose homes are in danger
B. provide an effective way to slow it down
C. help to its eventual solution
D. lead to its eventual solution(www.nmet168.com)
It is not feasible to build sea defenses to protect against erosion because ________.
A. house agents along the coast do not support the idea
B. it is too costly and will endanger neighboring areas
C. the government is too slow in taking action
D. they will be easily knocked down by waves and currents
