在英语写作中，一个优美且有力的结尾往往能够起到画龙点睛的作用，让整篇作文更加出彩。以下是一些可以用于英语作文结尾的优美句子：

总结观点式结尾。这种结尾方式适用于各种类型的议论文和说明文。例如：“In conclusion, it is clear that the advantages of regular exercise far outweigh the disadvantages. Not only does it improve our physical health, but it also has a positive impact on our mental well - being.（很明显定期锻炼的好处远远超过坏处。它不仅改善我们的身体健康，还对我们的心理健康有积极影响。）”通过简洁地总结前文所论述的观点，再次强调主题，使读者对文章的核心内容有更清晰的印象。又如在一篇关于环保的作文中可以这样结尾：“To sum up, protecting the environment is not just the responsibility of the government and large organizations; every individual should take action. Only when we all work together can we create a cleaner and more sustainable world for future generations.（总而言之，保护环境不仅仅是政府和大型组织的责任；每个人都应该采取行动。只有我们大家共同努力，才能为后代创造一个更清洁、更可持续的世界。）”这个结尾既总结了全文对于环保责任的讨论，又呼吁大家共同行动起来，升华了主题。

提出建议式结尾。如果文章是针对某个问题进行分析和探讨，在结尾处提出合理的建议是一个很好的选择。比如在一篇关于青少年沉迷手机游戏的作文结尾可以写：“Therefore, it is high time that we took effective measures to address this issue. Parents should monitor their children's screen time and guide them to engage in more meaningful activities. Schools can also organize more extracurricular activities to enrich students' lives. Only in this way can we help teenagers break free from the addiction to mobile games and grow up healthily.（因此，我们是时候采取有效措施来解决这个问题了。父母应该监督孩子的屏幕使用时间，并引导他们参与更多有意义的活动。学校也可以组织更多的课外活动来丰富学生的课余生活。只有这样，我们才能帮助青少年摆脱对手机游戏的沉迷，健康成长。）”这种结尾针对问题给出了具体的解决办法，体现了作者对问题的深入思考和解决问题的决心。再如在一篇关于改善城市交通拥堵的文章中可以说：“In view of the increasingly serious traffic congestion in cities, I suggest that the public transportation system be further improved. More buses and subways should be put into use, and the routes should be optimized. At the same time, citizens are encouraged to choose greener modes of transportation, such as cycling and walking. With these efforts, we can hopefully alleviate the traffic pressure in urban areas.（鉴于城市交通拥堵日益严重的情况，我建议进一步改善公共交通系统。应投入更多公交车和地铁使用，并且优化路线。同时，鼓励市民选择更环保的出行方式，如骑自行车和步行。通过这些努力，我们有望缓解城市地区的交通压力。）”

此外，引用名言式结尾也能为文章增色不少。名言警句通常具有深刻的内涵和广泛的认同感。例如在一篇关于坚持的作文结尾可以写：“As the saying goes, 'Where there is a will, there is a way.' We should always keep this in mind and never give up in the face of difficulties. Only by persevering can we achieve our goals and realize our dreams.（俗话说，'有志者事竟成'。我们应该始终牢记这一点，在困难面前永不放弃。只有坚持不懈，我们才能实现目标和梦想。）”引用名言使结尾更具权威性和说服力。又或者在一篇关于友谊的文章中结尾：“'A friend in need is a friend indeed.' This old saying reminds us of the true value of friendship. We should cherish our friends and support each other through thick and thin.（'患难见真情'这句古老的谚语让我们想起了友谊的真实价值。我们应该珍惜我们的朋友，并在艰难困苦中相互支持。）”这样的结尾既简洁又有深度，能让读者在读完文章后产生共鸣。

英语作文的结尾可以通过总结观点、提出建议或者引用名言等方式来使文章更加完整和优美。无论是哪种方式，都要紧密围绕文章主题，做到简洁明了、富有力度，给读者留下深刻的印象，让文章的质量得到进一步提升。
