2 What do you think people should do in an earthquake

Trapped in the Quake. 或From Fear to Relief.（答案不唯一）
The Highfield earthquake
It was about two o‘clock in the afternoon. I was working when the earthquake started. At first, I felt a slight /sla t/ shake/ e k/. Then I heard a loud noise like thunder/'θ nd (r)/.
Soon the real noise came, like bombs/b mz/ under the ground. The earth started to shake. People shouted /' a t d/ in fear /f (r)/.
Some ran out of the building. I tried my best to run out too. Outside, people were running in all directions /d 'rek ( )nz/ while pieces of glass and bricks /br ks/ were raining down. Then the walls began to come down too!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
长难句分析：这是一个含有时间状语从句的复合句。主句主语是people，谓语是were running，in all directions 是方式状语。从句是由while 引导的时间状语从句，while 表示两个动作同时发生。
~~~~~~
“坍塌；倒下”，其他含义：①下来；落下 ②（价格、温度等）下降 ③（飞机）着陆；降落
Finally, the noise and shaking ended. It was dark and silent /'sa l nt/ around me. I couldn‘t see anything at all, and I didn’t know if/ f/ anyone else was around me. I felt nervous/'n v s/ and my heart was beating /'bi t / really fast. “I‘m trapped,” I said to myself.
~~ ~~~
not... at all “一点也不”
~~~~~~~~~~~~~~~~~~
宾语从句，作know 的宾语。
A moment of fear went through my mind, but I told myself to calm /kɑ m/ down since/s ns/ I was still alive.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~
长难句分析：这是一个由并列连词“but”连接的并列复合句。第一个分句是一个“主谓状”结构的句子；第 二个分句的主语是I，谓语是told，宾语是myself，to calm down 是不定式短语作宾语补足语，since I was still alive 是since 引导的原因状语从句。
I shouted for help. I thought somebody could hear me but no one came for a very long time. I knew I had to save energy and wait for help.
Hours later, as I was trying to find my way out, I suddenly heard some noise above me. ”Help! Please help! I’m here!“
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
长难句分析：这是一个复合句。从句是由as 引导的时间状语从句，其中find one’s way out 意为“找到某人出去的路”；主句主语是I，suddenly 是副词，谓语是heard，some noise 是宾语，above me 是介词短语作状语。
I cried out in a weak /wi k/ voice /v s/. Then I heard shouts from excited people. They quickly moved away the bricks. At last, I was safe!
