If you go into a forest with your friends, stay with them. If you don't, you may get lost. If you get lost, this is what you should do: Sit down and stay where you are. Don't try to find your friends—let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle(吹口哨) three times. Stop, then shout or whistle three times again. Any signal(信号) given three times is a call for help.
Keep shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles back. When a signal is given twice, it is an answer to a call for help.
If you don't think that you will get help before night comes, try to make a little house with branches. Make yourself a bed with leaves and grass.
When you need some water, you have to leave your little house to look for it. Pick off small branches and drop them when you walk, then you can go back again easily. When you are lost, the most important thing is to stay in one place.

【分析】
本题是关于森林迷路后应对方法的英语阅读理解题，解题思路为：先通读全文把握核心内容，再针对每道题的题干关键词定位原文对应段落，逐一分析选项排除错误答案，选出正确选项。具体各题：第1题定位迷路后的应对措施，第2题定位回应求救的信号次数，第3题理解划线句含义，第4题归纳全文主旨。
【解析】
1. 第1题：根据第一段内容，迷路后应待在原地，通过三次呼喊或吹口哨发求救信号。A选项“找朋友”与原文“不要尝试找朋友”矛盾；C选项“在森林里四处走”与“待在原地”矛盾；D选项“尽量大声喊”不符合原文“三次呼喊”的要求，故选B。
2. 第2题：根据第二段最后一句“When a signal is given twice, it is an answer to a call for help”可知，回应求救信号需两次呼喊，故选B。
3. 第3题：划线句意为“走路时摘下小树枝丢下，就能轻松返回”，说明作者认为在森林里容易迷路，需要标记路线，故选A。
4. 第4题：全文围绕“在森林里迷路后应该做什么”展开，A选项“如何在森林旅行”、B选项“如何在森林过夜”、C选项“如何找水”均为局部内容，只有D选项概括了全文主旨，故选D。
