Push the breastbone up and down to a depth of about 5 cm about 30 times, at a rate of 100 beats per minute. Step 3. Give rescue breaths. Make sure the airway is open, and pinch (捏) the nose so it closes. Gently raise the chin (下巴) upwards with two fingers of your other hand. Take a deep breath, put your mouth over the patient's, and blow until you can see his chest, rise.

As you first hit the freezing water, you will almost breathe quickly at once. Remember to get control of your breathing and not to move around. 2 This means that it takes about one minute to gain control of your breathing, ten minutes to move before you get too cold. The final one is to remind you that it will take one hour before you become unconscious. Take that first minute and fully focus on your breathing. Slow it down, and then look around to see if you can locate the thickest area of ice. When you locate the ice, stretch your arms over the surface, and then begin to flutter-kick (上下打水) until your body becomes horizontal with the surface. 3 It is possible that you can live for several hours after passing out. This, however, does require some planning. You only have about 10 minutes before your muscles and nerves become too cold to work. Besides, what if you feel too weak to go on and you cannot get out? 4 The point is to encourage your coat to freeze to the ice, so that if you lose consciousness, you will keep your head out of ice. 5 A．It can help to remember the “1-10-1 principle”． B．However, if you remain calm, it can save your life. C．Place your arms over the surface of the ice and remain still. D．Thus you will remain visible for rescue, even if you pass out. E．Kick hard and use your arms and hands to climb out of the water. F．Remember that you should always stay off ice that's only 3 inches. G．Remove any clothing or heavy objects that are weighting you down. 【语篇解读】　这是一篇说明文。本文作者主要介绍了在结冰的湖面上跌倒遇到危险如何自救。 1．解析：选B　由前句的terrifying和后句的 “help you survive”可知，此处为转折关系，故B项(然而，如果你保持冷静，它可以拯救你的生命。)为正确答案。 2．解析：选A　此空与后一句 “This means that it takes about one minute to gain control of your breathing, ten minutes to move before you get too cold. ”形成概念与解释关系，后一句解释了“1-10-1法则”。 3．解析：选E　根据原文，落水后你有一分钟时间确定位置，那下一步一定是想办法如何爬出水面。 4．解析：选C　此空是对上一句问题的解答。没有力气爬出来怎么办，那应该让自己的胳膊支撑在冰面上，并保持不动。 5．解析：选D　上一句说解救自己的关键是让自己的衣服与冰冻在一起，目的在于自己失去意识前能够将头部露出冰面，这样就能够被他人发现，以得到解救。 Ⅲ.语法填空 Traditional Chinese medicine(TCM)isn't 1.
