英语短语 "would rather…than" 核心含义是 “宁愿……而不愿……”，用于在两个选项中明确优先选择前者、拒绝后者，强调主观偏好或意愿。
表示主语自己在两个动作中选择前者，前后动词均用原形（需保持平行）。
I would rather walk than take a bus. 我宁愿走路也不愿坐公交。
She would rather study alone than work in a group. 她宁愿独自学习也不愿小组合作。
若涉及别人的动作（希望他人做/不做某事），从句需用虚拟语气（一般过去时表示现在/将来的愿望），than后保持一致。
I would rather you told me the truth than lied to me. 我宁愿你告诉我真相，也不愿你骗我。
He would rather his sister helped him with homework than his brother did. 他宁愿姐姐帮他做作业，而不是哥哥。
否定可加在would rather后（不愿做前者）或than后（不愿做后者），根据语义调整。
I would rather not go to the party than wear that dress. 我宁愿不去派对，也不愿穿那条裙子。
She would rather study hard than not pass the exam. 她宁愿努力学习，也不愿考试不及格。
用于询问对方偏好，结构与肯定句一致。
Would you rather eat pizza than hamburgers? 你宁愿吃披萨也不愿吃汉堡吗？
Would he rather play football than basketball? 他宁愿踢足球也不愿打篮球吗？
1、 动词形式一致：than前后的动词必须保持相同形式（原形或过去式，取决于是否虚拟），不可混淆（如不用动名词/不定式）。
❌ 错误：I would rather to go than stay.
✅ 正确：I would rather go than stay.
2、 虚拟语气规则：当涉及“希望他人做某事”时，从句动词用一般过去时（即使描述将来）。
❌ 错误：I would rather you come tomorrow.
✅ 正确：I would rather you came tomorrow.
3、 可省略重复成分：若than后的主语/动作与前文重复，可省略重复部分（但动词仍需保持原形/过去式）。
I would rather stay at home than (stay) in the library. 我宁愿在家也不愿在图书馆。
两者都表示偏好，但结构不同：
would rather…than：后接动词原形（强调“动作选择”）；
I would rather read than watch TV. 我宁愿读书也不愿看电视。
prefer…to…：后接动名词/名词（强调“事物偏好”）；
I prefer reading to watching TV. 我更喜欢读书而不是看电视。
"would rather…than"是表达主观偏好的高频短语，核心是“选A不选B”。记住以下口诀：
自己做，用原形；别人做，用过去；
前后要平行，否定加not；
疑问把would提前，虚拟语气别忘改。
通过例句多练习，就能熟练掌握啦！
