课时作业(20) Unit 5 Period 4（Word练习）-【金榜题名】2026-2027学年高二英语选择性必修第二册高中同步学案（人教版）

课时作业(二十)　Unit 5　Period 4 Ⅰ.阅读理解 A Sunstroke is a condition that can quickly go from dangerous to deadly，especially if proper care isn't given immediately. Sunstroke，sometimes called heatstroke，is a result of the body temperature rising above the safe limit. This causes the body's necessary functions to stop working. It's usually pretty easy to avoid sunstroke，as long as proper action is taken. In that case，you need to act as quickly as possible to return that person's body to a safe temperature. Here are a few tips to help treat sunstroke. Call for help Call to get an ambulance as quickly as possible. This should be the first thing you do，especially if the sunstroke person has fainted(昏倒)．Also，call for help from anyone nearby if you're in a public place. If there's no one around，call someone nearby if they can get there sooner than an ambulance. Ask everyone to bring you as much water as possible，if there isn't much nearby. Get the person to a cooler area If there's a building nearby，aim for that. Anywhere with plenty of air conditioners and water is perfect. If a building isn't available，bring the person to a well-shaded area. Get the water flowing If the person is still conscious，get him or her to drink water. If there's a bathtub available，fill it with cool water and put the person in it. If your water supply is limited，you have to save it. Dampen a towel or shirt and put it on the person's body. Focus on the face，neck，and chest. Fan the person Getting moving air over the person cools him or her down. Use anything，a towel or sheet，a shirt，your hands，or a piece of board. This is where having many people around really helps，as they can combine to fan the entire body. 1．When does a person get sunstroke? A．When the body doesn't function.

A bit young to be a first aider，aren't you? You might think that，but in fact I've been doing this for almost a year now.I already have a huge amount of valuable experience. Why did you join the British Red Cross? I've always been interested in first aid，so when I saw some Red Cross volunteers at a local event I went over for a quick talk.After hearing what they had to say，I jumped at the chance of joining. What's the big attraction? As soon as you've treated an injured man，you will never look back.I've treated many types of injury now，from cut fingers to even heart disease cases.It's endlessly challenging and interesting. What have you learned? I'm now a skilled volunteer，which means I have additional qualifications(资历) on top of my standard first aid certificate(证书)．For example，I'm qualified to use Entonox (laughing gas) for pain management.First aid with the Red Cross is a whole lot more than just cleaning and dressing wounds. Any standout memories? Once，my colleague and I attended a call.As we approached the scene，all I could see was someone lying perfectly still on the floor.When you realize that someone is helpless and completely depending on you to do the right thing，you will feel this sudden rush of responsibility.But fortunately，our training means we have the confidence and knowledge to deal with such situations. Best thing about being an event first aider? You get to help people，while also enjoying the chance of going to lots of great events.It is really a win-win situation. 5．We learn from the text that Liam Mills .

Also you can ask for his name, if he knows what has happened, and then about his interests. 3 . You'd better listen to the sound of air coming in and out, and feel for air using the side of your face. If there are no signs of breathing, place two fingers under the chin and gently guide the face pointing upwards to open up their airways. Perform 30 chest compressions (胸外按压) and two rescue breaths as part of CPR. 4 . And then press the chest down about 2 inches at a rate of 100 compressions per minute. After 30 compressions, give two rescue breaths, done by opening the airways, closing the nose and fully covering the mouth hole. Make sure the person is warm as you wait for medical help.

Here are some tips for first aid(下面是一些急救的小窍门)符合语境，故选D。 2．解析：选B　细节句。根据空前“Care for the person who has just gone through serious damage, including both physical treatment and emotional support.”以及空后的“Let the person know that help is on its way and that everything will be all right.”可知，B. Remember to stay calm(记住要保持冷静)符合语境，故选B。 3．解析：选G　主旨句。根据空后“You'd better listen to the sound of air coming in and out, and feel for air using the side of your face.”可知，G. If a person is in a state similar to sleep, he may need checking for breath符合语境，故选G。 4．解析：选F　细节句。本段主要讲的是如何实施心肺复苏，下文中的And then是解题关键。由此可推断设空处应有逻辑衔接词first，故选F。 5．解析：选A　细节句。根据空前“However, if the person has heatstroke, do not cover him or keep him warm.”(但是，如果这个人中暑了，不要盖住他或让他保持温暖)可知，A．Instead, try to cool him(相反，试着给他降温)符合语境，故选A。 Ⅲ.语法填空 CPR is an effective form of first aid 1.

And the chest compression should start again right after two breaths are given. Learn CPR, for you never know when you might need 10. . And it feels good to know that you could help in an emergency. 【语篇解读】　本文是一篇关于如何实施CPR(心肺复苏)的科普文章。 1．given　考查过去分词。句意：心肺复苏是一种对心脏突然停止跳动的患者进行急救的有效方式。该句有系动词is，故设空处应使用非谓语动词，give与其逻辑主语之间是被动关系，故使用过去分词given，此处相当于定语从句which is given to the victim...。 2．survival　考查名词。句意：实施心肺复苏可以增加患者存活的希望。the victim's后接名词，故使用名词survival。 3．simply　考查副词。句意：只有三个步骤。设空处修饰系动词are，应使用副词，故用simply。 4．In　考查介词。句意：用这种方式，它可以使血液流向大脑、心脏和其他器官。in this way为固定短语，意为“用这种方式”。 5．the　考查冠词。句意：进行按压时，将一只手放在另一只手上，连续多次用力按压患者的胸部，每次按压至少按下2英寸深。 人共有两只手，一只用one，两个中的另一个则用the other。故用定冠词the。 6．pushing　考查现在分词。句意：见上句。该句已有谓语动词，故此处应用非谓语动词形式，又因push与谓语动词表示的动作几乎同时发生，且与逻辑主语即省略的you构成逻辑上的主动关系，故使用现在分词pushing，作伴随状语，相当于and push。 7．is completed/has been completed　考查动词的时态和语态。句意：然后在按压完成后，检查呼吸道，看这个人是否在呼吸。 after引导时间状语从句，从句中缺少谓语，根据语境可知，应用一般现在时。且complete与主语compression构成被动关系，故使用一般现在时的被动语态is completed。又因该动作发生在主句谓语动词表示的动作之前，故也可以使用has been completed。 8．to see　考查动词不定式。句意：见上句。该句谓语动词为check，故此处使用非谓语动词形式，根据下文“看看这个人是否在呼吸”，表目的，故使用不定式to see作目的状语。 9．which　考查定语从句。句意：如果没有呼吸，就进行口对口人工呼吸，这有助于将氧气输送到患者的肺部。设空处引导非限制性定语从句并在从句中作主语，先行词指物，故应使用which。 10．it　考查代词。句意：学习心肺复苏，因为你永远不知道什么时候你可能会用到它。need后缺少宾语，根据句意可知，此处指的是心肺复苏，为避免重复，使用it来代替。 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
