Dear fellow students, I’m writing to call on everyone to help the people in the disaster-stricken area. A terrible flood has struck our neighbouring county. Many people have lost their homes and are now in urgent need of help. As members of a big family, we should do our part. The disaster has destroyed thousands of houses, leaving many people trapped or injured. Some are even in shock. Although the rescue workers have been on hand to offer aid, more supplies are needed, such as food, water, medicine, and first aid kits. The power and water supply have also been cut off, making the situation even worse. We are calling on everyone to donate what you can — money, clothes, or daily necessities. Every small effort counts. As the saying goes, “Unity is strength.” Let’s come together to help the victims survive this difficult time. The survival of many people depends on our timely help. Don‘t wait! Your kindness can make a difference. Join us and deliver hope to those in ruins! The Students’ Union 五、读后续写：如何用单元词汇写“灾难与希望”主题 “灾难与希望”是读后续写的高频主题，情感递进四步法，融入本单元词汇： 第一步：灾难降临（用 strike, destroy, in ruins, in shock） Without warning, the earthquake struck. Within seconds, the whole city lay in ruins. Buildings were destroyed, and people were running in all directions, screaming in shock. 第二步：困境与无助（用 trap, suffer, shelter, evacuate） Many people were trapped under the fallen bricks. They suffered from hunger and thirst. The survivors had no shelter and had to evacuate to the open areas. 第三步：救援与希望（用 rescue, effort, supply, deliver, revive） Rescue workers arrived quickly with helicopters and first aid kits. They made every effort to rescue the injured. Food and water were delivered to the affected areas. The hope began to revive. 第四步：重生与感悟（用 survive, unify, wisdom, effect） The disaster brought great damage, but it also unified the whole nation. People realized that only through calm thinking and joint efforts could they survive such a crisis. It was a lesson of wisdom and courage. 六、读后续写主题范文：《废墟中的希望》 【题目场景设定】 一场大地震摧毁了李华所在的小镇。他和家人被困在废墟下，凭借冷静和意志，最终成功获救。 范文： Li Hua’s Story: Surviving the Earthquake Li Hua never expected that a deadly earthquake would strike his peaceful town. The ground shook violently, and within seconds, everything was in ruins. He found himself trapped under heavy bricks and metal, with darkness all around. He could hardly breathe. His legs were badly injured, and he could feel the shock and fear creeping in. But he knew he had to stay calm. He remembered his father’s words: “Even if everything is lost, hope still exists.” Hours passed. He began to suffer from thirst and exhaustion, but he refused to give up. He tapped on the pipe beside him, hoping someone might hear. Then came a faint whistle — the rescue team had arrived! He shouted with all his strength. Soon, the rescuers delivered him from the ruins. His family survived. Looking at the destroyed buildings, he realized that disasters could ruin houses, but they could never destroy people’s determination. The effort and unity of the rescue workers affected him deeply. He knew that he would set an example of wisdom and calm for others in the future. The disaster had ended, but his new life had just begun. 范文亮点句解析： 1.开头突转：Li Hua never expected that... —— 用“从未想到”制造反差，瞬间带入灾难场景。 2.感官细节：darkness all around / could hardly breathe —— 视觉+触觉，营造紧张氛围。 3.内心独白：“As if everything is lost, hope still exists.” —— 引用内心格言，增强人物韧性。 4.救援信号：tapped on the pipe / faint whistle —— 动作细节+声音描写，制造紧张感和转折点。 5.结尾升华：The disaster had ended, but his new life had just begun. —— 结尾反转，呼应标题，深化主题。 1 学科网（北京）股份有限公司 $
