下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。请根据文章的内容，从每题所给的4个选项中选择1个最佳答案。 第一篇 First Aid First aid is emergency care for a victim of
sudden illness or injury until more skillful medical treatment is available. It
may save a life or improve certain vital signs including pulse, temperature, a
clear airway (气道), and breathing. In minor emergencies, first aid may prevent a
victim’s condition from turning worse and provide relief from pain. First aid
must be administered as quickly as possible. In the case of the critically
injured, a few minutes can make the difference between complete recovery and
loss of life. First-aid measures depend upon a victim’s needs
and the provider’s level of knowledge and skill. Knowing what not to do in an
emergency is as important as knowing what to do. Improperly moving a person with
a neck injury, for example, can lead to permanent spinal (脊柱的) injury and
paralysis (瘫痪). Despite the variety of injuries possible,
several principles of first aid apply to all emergencies. The first step is to
cal*l for professional medical help. The victim, if conscious, should be
reassured that medical aid has been requested, and asked for permission to
provide any first aid. Next, assess the scene, asking other people or the
injured person’s family or friends about details of the injury or illness, any
care that may have already been given, and preexisting conditions such as
diabetes (糖尿病) or heart trouble. The victim should be checked for a medical
bracelet (手镯) or card that describes special medical conditions. Unless the
accident scene becomes unsafe or the victim may suffer further injury, do not
move the victim. First aid requires rapid assessment of victims
to determine whether life-threatening conditions exist. One method for
evaluating a victim’s condition is known by the acronym (首字母缩写语) ABC, which
stands for: A - Airway: is it open and clear
B - Breathing: is the person breathing Look, listen, and feel for
breathing. C - Circulation: is there a pulse Is the person
bleeding externally Check skin color and temperature for additional indications
of circulation problems. Before we administer first aid to a victim, it is very important for us
A．to refer to all kinds of handbooks on first aid. B．to make sure what to do and what not to do. C．to remove the ring or bracelet he may be wearing. D．to take him to a hospital at once.
