Sprained（扭伤）Ankle

One of the most common injuries teenagers and adults experience is a sprained ankle.A sprain occurs
when the ligaments（韧带）of a joint are twisted（扭伤）and possibly torn. Ligaments are bands of fibers that
hold the bones of a joint in position.A sprain can occur from a sudden twisting at the joint,or a stretching or
tearing of the fibers of the ligaments. The injured area usually swells（肿胀）and becomes black and blue.
Stepping off the sidewalk at the wrong angle or having one foot land in a hole while walking or running can
leave you rolling on the ground in pain with an ankle on fire!If you cannot walk without experiencing intense
pain,you must seek medical help.If the pain is manageable,and you can walk,here are three words to help
you remember how to treat yourself:
●Elevate（抬高）
●Cool
●Bandage（打绷带）
As soon as there is injury to that ligament,there will be a certain amount of bleeding under the skin.
Once the blood pools around the damaged blood vessels,swelling occurs.The pressure from the swelling
results in additional stress and tenderness to the region.In order to reduce the degree of swelling,lie down as
soon as possible and keep the ankle elevated so that it is actually higher than your heart.Next,to reduce
blood distribution and keep bleeding（流血）to a minimum, apply a cold pack. After 20 minutes, take the
pack off,wait half an hour and then reapply.This can be done several times a day for a total of three
days.
Never leave a cold pack on for more than 20 minutes at a time.Reducing the temperature in that area for
an extended period of time signals the body to increase blood flow to raise the body temperature!Therefore,
one accidentally triggers（引起）more blood distribution to the affected area by leaving a cold pack on for too
long!Finally,bandage the ankle.Be careful not to wind it too tightly;doing so can restrict blood flow and
cause harm to the entire foot.

选项 The black-and-blue symptom of a sprain is due to________. A:pressing one's ankle B:a tight bandage C:applying a cold pack D:bleeding under the skin

答案 D

解析由文章第一段第二句“A sprain occurs when the ligaments of a joint are twisted...”可知选C。
由文章第一段第五句“The injured area usually swells and becomes black and blue”可知受伤的地方会肿起来而且皮肤会青一块紫一块。’
由第二段第四行it前的“keep the ankle elevated”可知是将脚躁抬高，使其超过心脏的位置。
由文章第二段倒数第二句“wait half an hour, and then reapply”可知选A。reapply意为 “重新做”。
通读全文可知，文章主要讲的是当脚躁扭伤时，我们应该怎样进行处理：故选B。第二篇文章主要介绍了人们对艾滋病的看法。
