Pupils’ lives spared during Falmont earthquake
By Raymond Tran
18 March
FALMONT - On 17 March,476 students and 36 teachers at Falmont Primary School escaped① an earthquake that hit the county② at 2:27 p. m.Only 5 students suffered slight injuries③,despite the current④ figures of 7 killed and over 200 injured in the disaster⑤ area at large⑥.
Alice Brown,head teacher at Falmont Primary School,was teaching when the floor began to shake.【1】 Her students’ reaction⑦ was quick and correct—they moved under their desks,head first,and held on to⑧ the legs of the desks. At the same time,Miss Brown quickly opened the classroom door,in case【2】 it became damaged during the shaking and could not open. There were loud crashes⑨ of glass breaking and things falling to the ground,but the students remained still and waited calmly and quietly.
【1】be doing... when... 正在做……这时(突然)……。
【2】in case以防……。后常跟that从句,that可省略;如果跟短语,则使用in case of。
The moment the shaking stopped,Miss Brown sensed⑩ it was the best time for the class to make their escape.【3】 She signalled to her students to exit the classroom in an orderly line covering their heads with their hands.【4】Within one minute and twenty seconds,the whole class went down the stairs and rushed to the playground. Soon students from other classes arrived too. After a roll call confirmed that all were safe and sound, they relaxed,laughing,crying and hugging each other.【5】

Girl saves 100 from tsunami
By Jessie Cable
21 December
NEWDALE -On 20 December,a series of huge waves caused by an undersea earthquake raced across the ocean near Goldshore and left thousands dead.【6】 Goldshore Beach was the only local beach to survive the disaster without any loss of life. A 10yearold girl,Sabrina Andron,helped around 100 people escape danger with her knowledge of tsunamis.
【6】caused by an undersea earthquake为过去分词短语作定语,修饰名词waves;left thousands dead为“leave +宾语+宾语补足语”结构。
The day began like any other on Goldshore Beach. People were walking,running or simply sitting on the sandy beach,enjoying the warm sea air and the soft wind that brushed their hair.【7】 Sabrina was one of the happy tourists until she noticed something odd.“The water was like the bubbles on the top of a beer,” she later explained.“It wasn’t calm and it wasn’t going in and then out. It was just coming in and in and in.” Sabrina had just learnt about tsunamis in a Geography lesson. It immediately occurred to her that these were signs of an approaching tsunami.【8】
【7】画线部分为动词ing形式作伴随状语;that引导定语从句,修饰先行词the soft wind,that在从句中作主语,不可省略。
【8】画线部分it作形式主语,that引导的从句作真正的主语。
Sabrina was frightened,but she soon kept her head.She warned her parents of the danger,though at first they just thought she was joking. However,Sabrina was certain that a terrible disaster was on its way and kept asking her parents to talk to a safety officer. To her great relief,the officer immediately realized the coming danger. The beach was rapidly cleared ofpeople,just before the huge waves crashed into the coast.

弗尔蒙特发生地震 小学生成功逃生
雷蒙德·特兰
3月18日
弗尔蒙特——3月17日下午2:27,一场地震袭击了弗尔蒙特县,弗尔蒙特小学476名学生和36名教师成功逃生。尽管目前整个灾区伤亡数字为7人死亡,200多人受伤, (弗尔蒙特小学)却仅有5名学生受轻伤。
弗尔蒙特小学校长艾丽斯·布朗当时正在授课,突然地面开始晃动。她的学生们反应迅速正确——他们头朝里,钻到桌子下面,并紧紧抓住桌腿。与此同时,布朗女士立刻打开教室门,以防门在震动中损坏打不开。尽管玻璃破碎、东西倒地发出阵阵巨响,但是学生们仍然一动不动,沉着安静地等待着。
晃动一停止,布朗女士立即意识到这是全班逃生的最好时机。她示意学生们用双手护着头,排好队,有序离开教室。1分20秒内,全班下楼梯,跑到了操场上。很快,其他班的学生也赶到了。点名确认所有人都安然无恙后,大家才松了一口气,笑啊,哭啊,互相拥抱着。
“我们每年进行两次地震安全步骤演练,”布朗女士说,“因此在地震时,孩子们都十分镇定,能够保护好自己。”
女孩拯救百人免遭海啸袭击
杰西·凯布尔
12月21日
纽代尔——12月20日,由海底地震引发的巨浪接连席卷了金海岸附近海域,造成数千人死亡。金海岸海滩是当地唯一一个在此次灾难中没有任何人员损失的海滩。一个10岁的女孩,萨布丽娜·安德龙,利用自己掌握的海啸知识帮助大约100人脱险。
那天刚开始,金海岸海滩上与往常一样。人们在散步、晨跑,或者就是坐在沙滩上,享受着温暖的海边空气和拂过发际的微风。萨布丽娜是这群快乐游客中的一位,直到她察觉到一丝异样。“海水像啤酒表面的泡沫一样,”她后来解释说,“不平静,也没有潮来潮去。海水只是一个劲儿地涌过来,涌过来,再涌过来。”萨布丽娜刚在一节地理课上学习了有关海啸的知识。她立刻意识到这是海啸来临的前兆。
萨布丽娜吓坏了,不过她很快冷静下来。她提醒父母有危险,但一开始他们只当她是在开玩笑。不过,萨布丽娜确信,一场可怕的灾难正在逼近,于是便不停地让父母去和安全员谈一谈。使她大为宽慰的是,安全员立即意识到危险即将来临。就在巨浪拍岸的前一刻,海滩上的人迅速疏散一空。
