知识清单
一、重点词组(教材Unit5核心)
1. in case of(万一~如果发生)
用法提示:后接名词或名词性短语,表假设
教材例句:Keep a first
aid kit at school in case of emergencies(教材Unit5:Keep a first
aid kit at home in case of emergencies)
核心搭配:in case of injury(万一受伤)、in case of bleeding(万一出血)
2. make a difference(发挥作用~产生影响~有帮助)
用法提示:可与to连用,后接名词
教材例句:Correct first
aid skills can make a big difference to the injured(教材Unit5:Your correct first
aid skills can make a big difference to the injured person)
核心搭配:make a difference to recovery(对康复有帮助)、make a difference to safety(对安全有影响)
3. call for(要求~需要~呼叫)
用法提示:后接名词,可表示"需要"或"呼叫"
教材例句:This emergency calls for professional first
aid treatment(教材Unit5:This kind of emergency calls for professional medical help)
核心搭配:call for help(呼救)、call for patience(需要耐心)
4. as soon as possible(尽快~尽早)
用法提示:副词短语,可置于句末或句中
教材例句:We should send the injured to the hospital as soon as possible(教材Unit5:Send the injured to the hospital as soon as possible)
核心搭配:treat as soon as possible(尽快治疗)、help as soon as possible(尽快帮助)
5. prevent from(防止~阻止~避免)
用法提示:常用prevent sb./sth. from doing结构,from可省略
教材例句:Wearing gloves can prevent us from getting hurt during first aid(教材Unit5:Wearing protective gloves can prevent you from getting hurt when giving first aid)
核心搭配:prevent from bleeding(防止出血)、prevent from infection(防止感染)
二、核心语法:省略(教材Unit5语法重点)
简化规则:状语从句中,主语与主句一致或为it,且含be动词,可省略主语和be动词
易错点:主语不一致不可省略;无be动词不可省略;省略后逻辑主语需与主句一致
教材场景例句:When giving first aid,we should stay calm(教材Unit5:When(you are)giving first aid,you must stay calm)
教材场景例句:If necessary,we can call for professional help(教材Unit5:If(it is)necessary,ask others for help while giving first aid)
三、基础练习题(考用法)
1. 填空:We must act ______ soon as possible to help the injured.(考查as soon as possible的搭配)
答案:as
解析:易错原因是遗漏as soon as possible的固定结构,对应教材Unit5"急救及时性"的核心考点
2. 翻译句子:在急救过程中,戴手套可以防止我们受伤。(考查prevent from的用法)
答案:During first aid,wearing gloves can prevent us from getting hurt
解析:易错原因是prevent from后接动名词的规则,对应教材Unit5"安全防护"的表达考点
四、变式练习题(考易错点)
1. 改错:While we gave first aid,we should follow the correct steps.(考查省略结构)
答案:While giving first aid,we should follow the correct steps
解析:易错原因是未使用省略结构,主句主语与从句主语一致且含be动词(可补全为while we are giving),对应教材Unit5省略语法考点
2. 选择:In case of ______,call the emergency number immediately.(bleeding/bleed)(考查in case of的用法)
答案:bleeding
解析:易错原因是in case of后接动词原形,此处需接名词,对应教材Unit5"紧急情况应对"的搭配考点
五、综合练习
1. 用所学词组和语法完成句子:万一发生紧急情况,正确急救技能会对伤者有很大帮助,我们应该尽快实施急救,同时防止自己受伤。
答案:In case of emergency,correct first
aid skills can make a big difference to the injured,and we should give first aid as soon as possible while preventing ourselves from getting hurt
2. 句型转换:When we are dealing with bleeding,we need to apply gentle pressure.(使用省略结构改写)
答案:When dealing with bleeding,we need to apply gentle pressure
六、拓展
同义替换:avoid(=prevent from,防止)、need(=call for,需要)、as soon as we can(=as soon as possible,尽快)
校园场景例句:In the school playground,we should know how to call for help in case of injury and avoid getting hurt when giving first aid(在学校操场,我们应该知道万一受伤如何呼救,并且在实施急救时避免自己受伤)
七、考点总结
词组重点:in case of的名词搭配、prevent from的动名词用法、as soon as possible的固定结构
语法重点:省略结构的适用条件、省略后的逻辑一致性
