What is Mr Green’s main purpose in having this class discussion
A. To check if students remember facts about disasters.
B. To give homework about emergency bags.
C. To help the class learn about staying safe together.
D. To find student volunteers for rescue work.
1. They are very powerful and dangerous.
Language points
powerful /'pa fl/ adj. 力量大的
powerful 强调“具有强大力量、能量或影响力的”，可用于描述物体、自然现象、人或组织等。
相关词汇：power n. 力量；权力 powerfully adv. 强烈地；强大地
e.g. The elephant is a powerful animal that can carry heavy loads.
大象是力量强大的动物，能搬运重物。
My dad bought a powerful computer to help with his work.
我爸爸买了一台功能强大的电脑来辅助工作。
2. When it comes to earthquakes, what should people do to stay safe
说到地震，人们为了保证安全应该怎么做？
分析结构：此句是含时间状语从句的特殊疑问句，结构为“时间状语从句(When it comes to + 名词/ 动名词)，特殊疑问句(特殊疑问词what + 情态动词+ 主语+ 谓语+ 其他)？”。
When it comes to ... 是固定句型，意为“当提到……时；说到……时”，用于引出话题，后接名词、代词或动名词(v.-ing)。类似表达：talking of ...(谈到……)、speaking of ...(说起……)。
e.g. When it comes to math, how do you solve difficult problems
说到数学，你如何解决难题？
When it comes to reading, she always shares interesting books with classmates. 说到阅读，她总是和同学们分享有趣的书籍。
3. If an earthquake happens, we should stay calm and quickly find shelter to protect ourselves from falling objects.
protect sb. from ... 保护某人免受……的伤害
e.g. Parents often try to protect their children from online dangers. 父母常试图保护孩子免受网络危险。
4. For typhoons, we should stay indoors, away from windows.
长难句分析：该句为简单句。For typhoons为介词短语作状语；主语是we；谓语是should stay；indoors为地点副词作状语；短语away from windows作状语，用于补充说明stay的状态要求。
5. We should shut all windows and doors.
shut 一词多义：(1) 作动词时，shut 可表示“关闭；(使)关门”，过去式和过去分词均为shut。
(2) 作形容词时，shut 常用于“be shut”结构，表示“关闭；停业”。
常见搭配：(1)shut the door/window 关上门 / 窗
(2) shut down(使)(系统、大型设备)停止运转；(机构、企业)关闭
(3) shut off 切断煤气(或水等)的供应；停止供应煤气(或水等)；关闭机器
e.g. Remember to shut the window before you leave the room.
离开房间前记得关上窗户。
The store shuts at 9 p.m. every day. 这家商店每天晚上 9 点关门。
The restaurant has been shut for renovations since last week.
这家餐厅从上周起停业装修了。
6. If there is a wildfire nearby, we should follow what authorities advise and leave if necessary.
长难句分析：该句为复合句。If there is a wildfire nearby为条件状语从句；主句中，we是主语，should do和(should) leave为并列谓语，由and连接；what authorities advise作follow的宾语；if necessary为省略的条件状语从句，完整形式为if it is necessary，补充说明leave的前提条件。
advise 动词，意为“建议；劝告”。
常见用法：(1) advise sb. to do sth. 建议某人做某事，后接不定式作宾补；
(2) advise doing sth. 建议做某事；
(3) advise sb. against (doing) sth. 劝告某人不要做某事；
(4) advise + that 从句，从句用虚拟语气，谓语为“should +动词原形”，should 可省略。
相关词汇：advice 不可数名词，意为“建议”，需搭配量词使用，例如：a piece of advice 一条建议。
e.g. My teacher advised me to read more books to improve writing skills.
我的老师建议我多读书以提高写作能力。
The doctor advised him against staying up late every day.
医生劝告他不要每天熬夜。
We advised that she (should) take a break before the exam.
我们建议她考试前休息一下。
