Hospital emergency rooms treat injured fingers all the time． Without treatment, a bad cut can lead to permanent damage．But how should a person know when a bleeding cut is serious enough to require medical attention?
Here are some tips from Dr． Martin Brown, chairman of the department of emergency at Inova Alexandria Hospital in Virginia．
1． Laceration （裂口）
The medical term for a cut or tear in the skin is a laceration．71 A long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep． However, if you have a short but deep laceration, you will need professional attention．
2． Fingertips cut off
Some injuries, like a fingertip that gets cut off, might even need surgery to repair．72 More often, cutting down the bone is what is done because reattaching a fingertip is often not successful．
3． Bleeding
73 Small cuts usually produce what is known as venous （静脉的） bleeding． This means the blood flows steadily from the injury． The bleeding will often stop when pressure is put on the wound． In most cases holding direct pressure with a clean cloth for four to rive minutes would do．But if a cut appears to be pumping blood out with some force, this may be a sign of arterial （动脉的）bleeding． 74
Finally, always keep this in mind: even a cut that does not require medical attention must be kept clean to prevent infection． Small cuts should be cleaned gently with clean water． 75 Then cover it with a clean, dry bandage．
A． How a wound bleeds can be a sign of how serious it is．
B． That requires a specialist to either cut down the bone or reattach the fingertip
C．This kind of injury should be treated by a medical professional as soon as possible．
D．The first signs of this disease include difficulty in opening the mouth．
E．Use a washcloth to clean the area if the wound is dirty．
F．With a cut finger, holding the hand above the heart can reduce the loss of blood．
G．The length-is usually not as important as the depth．

In 1990 a report was published about what the earth might be like 20 years from then on. 71 According to the report,the picture of the earth in the year 2010 is not a pleasant one. 72 The population could be as large as 6300 million,almost 2150 million more than in 1985.More people would move into cities ,especially cities in developing countries.Cities like Cairo and Jakarta probably would each have 15 million by then.
73 Farmers will grow 90% more food than they did in 1985,but most of the increase would be in countries that already produce enough food for their people. 74 Poor farming ways are destroying large areas of crop land,changing farms into deserts.More farmland is lost as cities become larger and more houses are built.Air pollution will get worse as industrial countries burn more coal and oil.Many of the world's forests could disappear as more and more trees are cut down.Energy will continue to be a serious problem. 75 They only workde out the situation that exists today.By changing the situation,by settling the problems,the picture can be changed.There is still time for the nations of the world to work out a plan of action.But they warned that waiting too long to make de cisions would greatly reduce the chances of success.
