"worse than"是英语中比较级结构，核心含义是：比……更糟/更差/更坏/更恶劣。
其中：
"worse"是形容词/副词bad（坏的；差的）或ill（生病的；恶劣的）的比较级；
"than"是比较级的标志词，连接被比较的对象。
"worse than"用于比较两个事物的负面程度，可修饰名词、动词、形容词等，覆盖"情况、质量、行为、健康、感受"等场景。以下是常见用法分类：
用于描述某情况比另一情况更糟，常搭配be动词（am/is/are/was/were）。
The weather today is worse than yesterday.（今天的天气比昨天更糟。）
The traffic after the accident was much worse than usual.（事故后的交通比平时堵得多。）
The situation in the region is far worse than we expected.（该地区的局势比我们预期的恶劣得多。）
用于比较物品、服务、能力等的质量差异，强调"更差"。
This restaurant's food is worse than the one around the corner.（这家餐厅的菜比街角那家差。）
His English writing is worse than his speaking.（他的英语写作比口语差。）

"worse than"后可接完整从句或省略句（省略与主语重复的部分）。

1、 比较对象要对等：
被比较的两者需属于同一类别，避免逻辑错误。
错误：Her grades are worse than Tom.（她的成绩比汤姆差？→ 成绩 vs 人）
正确：Her grades are worse than Tom's.（= Tom's grades）
正确：She is worse at math than Tom.（她数学比汤姆差。→ 人 vs 人）
2、 程度副词的修饰：
可在"worse than"前加程度副词（如much/far/a lot/a little），强调"更糟的程度"。
This problem is much worse than I thought.（这个问题比我想的严重得多。）
The pain is a little worse than yesterday.（疼痛比昨天稍重一点。）
3、 固定表达：
worse than ever：比以往更糟
Example: His temper is worse than ever since he lost his job.（他失业后脾气比以前更差了。）
It's worse than that：更糟的是……（口语中用于引出更坏的情况）
Example: A: I missed the bus. B: It's worse than that—you forgot your wallet too!（A：我没赶上公交。B：更糟的是，你还忘带钱包了！）
"worse than"是负面比较的核心结构，本质是用"worse"（更糟）连接两个对象，突出前者比后者"更坏/更差"。只要记住比较对象对等和程度修饰的规则，就能灵活运用啦！
