英语作文的结尾部分应该简洁、有力，并且能够有效地总结文章的主要内容或重申文章的中心思想。以下是一些常见的英语作文结尾技巧：
重申主题：
在结尾段落中重新申明文章的主要论点，但要注意变换表达方式，避免直接重复前文内容。例如：“In conclusion, transitioning to renewable energy sources is crucial for addressing climate challenges and creating a healthier planet.”
总结论点：
如果文章中涉及多个分论点，可以在结尾段落中对这些论点进行总结。这样不仅可以强化文章的逻辑性，还能帮助读者更好地理解文章的核心内容。例如：“Regular physical activity boosts mood, reduces anxiety, and improves cognitive function, making it a natural remedy for mental health challenges.”
自然结尾：
随着文章的结束，文章自然而然地结尾。这种方式不需要过多的修饰，简洁明了地表达出文章的最后意思。例如：“After her death, I felt as if something were missing in my life. I was sad over her passing away, but I knew she would not have had any regrets at having given her life for the benefit of the people.”
引用名言或警句：
在结尾处引用名言或警句，可以为文章增添深度和文采。例如：“As Shakespeare once said, 'All's well that ends well.'”
提出建议或展望未来：
如果文章讨论的是某个问题，可以在结尾处提出一些建议，或者展望一下未来。例如：“In conclusion, to build a sustainable future, we must all take responsibility for our actions and make conscious choices.”
首尾呼应：
在文章的结尾，把含义较深的话放在末尾，以点明主题，深化主题，起到画龙点睛的效果。例如：“I love my home town, and I love its people. They too have changed. They are going all out to do more for the good of our motherland.”
选择合适的结尾方式取决于文章的内容和作者的意图。确保结尾部分与文章的整体风格和内容保持一致，并且能够给读者留下深刻的印象。
