Section_ⅠWarming Up & Reading —Prereading Now many hospitals suggest that we use the letters DR ABC to remember what to do when dealing with an emergency. Do you know what they stand for？Now read the following passage to get the answer.The most important thing to keep in mind when dealing with an emergency (紧急情况) is to stay calm. By staying calm we will be able to think what to do and make better decisions.Many hospitals suggest that we use the letters DR ABC to remember what to do when we have to think fast. D stands for danger. We should first of all make sure that the accident scene is no longer dangerous. If we were to get hurt trying to save someone, we would not be able to help. R is for response. We can do a lot of good by simply asking “A re you all right？” If the person can answer, we know that he or she is conscious and can breathe. The question will also calm the person, letting him or her know that help is on the way.A is for airway (呼吸道). We must make sure that a person's airway is open and it is easy to breathe. This can be done by gently tipping the person's head backslightly. B is for breathing. We should check that the person can breathe. Is his or her chest moving？If the person is not breathing, we must try to start his or her br eathing at once, using the mouthtomouth method. If this is not done within five minutes, the person will die. If a person is breathing but not conscious, it is usually best for him or her not to be moved. C is for circulation (循环；环流)．Is the person's blood circulating？We can look for colour, coughing, and eye movement. We can also check a person's pulse (脉搏) by putting a finger on the person's neck or wrist.This is what we call DR ABC, which can remind us of what to focus on when there is an emergency.Warming Up1.Look at the pictures and tell what happened.(1)The girl in Picture A cut_her_finger.(2)The girl in Picture B burnt_her_hand.(3)The man in Picture C got_an__electric_shock.(4)The woman in Picture D was_drowning.2．Nowadays there are a lot of unexpected accidents.What would you do in such situations?(1)What kind of first aid should you give to a snake bite?①The_person_bitten_must_get_a_doctor_or_go_to_hospital_at_once.②Speed_is_very_important.③It_will_help_the_doctor_greatly_if_you_can_tell_him_what_kind_of_snake_it_was,_or_describe_the_situation.(2)What kind of first aid should you give to bleeding?①Try_to_stop_the_bleeding.②Press_a_handkerchief_onto_the_bleeding_point_and_hold_it_there.③Hold_up_the_part_of_body_which_is_bleeding_if_possible.(3)What kind of first aid should you give to a sprainedankle?①Tied_with_medical_bandage.②It_is_better_to_avoid_walking_with_the_injured_ankle.③It_is_correct_to_use_ice_bag_for_removing_pain_and_bleeding,_and_also_not_influence_our_own_body_healing.(4)What kind of first aid should you give to a choke?To_treat_a_choke,_you_should_make_him/her_spit_by_patting_him/her_on_the_back.(5)What kind of first aid should you giveto a broken arm?①Do_not_move_the_patient.②Support_the_broken_arm_in_the_most_comfortable_position.③Get_medical_help_immediately.Fast Reading1．Read the text quickly and complete the main idea of it.The text mainly introduces (1)three types of burns and their characteristics as well as how to give (2)first_aid_treatment when burns happen.2．Scan the text and then choose the best answer according to the text.(1)In the text, burns are sorted according to the ________ of the skin burned.A．layer B．functionC．type D．area(2)Which of the following is NOT the function of the skin according to the text?A．It protects you against disease, poisons and the sun's harmful rays.B．It helps the heart beat.C．It can keep you warm or cool.D．It prevents your body from losing water and gives the sense of touch.(3)When cooling burns, cool water is used to do the following EXCEPT ________.A．stop the burning processB．prevent the pain becoming unbearableC．reduce swellingD．prevent any blisters being broken(4)Which of the following first aid treatment is RIGHT according to the text?A．Take clothing off the burned area even though it is stuck to the burn.B．Do not put cold water on second degree burns.C．If burns are on the face, the victim should sit up.D．If the injuries are second degree burns, it is unnecessary to get the victim to the doctor or hospital at once.(5)If someone gets burned and his hands get black and white and charred, it belongs to________.A．the first degree B．the second degreeC．the third degree D．none of the above答案：(1)～(5) ABDCCCareful Reading1．Read the text carefully and then fill in the blanks.BurnsCauses hot liquids, steam, fire, radiation, the sun, electricity orchemicals(1)Types First degree burns Second degree burns Third degree burnsCharacteristics◆dry, red andmildly(2)swollen◆mildly painful◆turn (3)whitewhen pressed◆rough, red andswollen◆blisters◆(4)watery surface◆extremely painful◆black and whiteand charred◆swollen; often(5)tissue underthem can be seen◆little or nopain if (6)nervesare damaged; maybe pain aroundedge of injuredareaFirst aid treatment◆Take off clothing and (7)jewellery near the burn.◆Place(8)cool,_clean, wetcloths on them untilthe pain decreases.◆Place cool clothson the burned arearepeatedly for(9)an_hour or so.◆Send the victim to the doctor orhospital at once.◆(10)Dry the burned area gently.◆Cover the burned area with a dry, clean (11)bandage.◆Keep burned arms or legs (12)higher than the heart.2．The text can be divided into five parts.Then find out the main idea of each part.Part 1：The_importance_of_skinPart 2：Causes_of_burnsPart 3：Types_of_burnsPart 4：Characteristics_of_burnsPart 5：First_aid_treatmentSummaryFill in the blanks according to the text.The skin, which acts as a barrier 1.against disease, poisons and the sun's harmful rays, is an essential part of your body.
