英语作文开头和结尾的万能句型可归纳为以下五类，结合权威信息源整理如下：

一、开头句型

1. 名人名言+转折

2. 数字统计+现象描述

   • 例：According to recent survey, about 78.9% of college students want to further their study after graduation.

   • 可替换场景：85% prefer bicycles for short-distance travel, 70% spend their leisure time on entertainment.

3. 固定表达+强调

   • It is high time that...（如：It is high time that we improve our English.）

   • From all the reasons above, it is evident that...（如：It is evident that studying English is necessary.）

二、结尾句型

1. 结论总结

   • Taking into account all these factors, we may reach the conclusion that...（如：We should encourage more students to use English.）

2. 建议呼吁

3. 观点升华

   • There are some people who hold different opinions about...（如：Some people think English is not essential.）

三、注意事项

• 编造数据 ：考试时可编造合理数字（如70%、85%），但需确保逻辑通顺；

• 避免雷区 ：不要使用虚假数据或生硬表达，优先选择权威句型。
