“Dirty”和“filthy”这两个英语单词都表示“脏的”，但它们之间存在细微的差别。简单来说，“dirty”指一般的脏，比较常见；而“filthy”则表示非常脏，令人作呕，程度更深。 “Filthy”通常暗示着一种不卫生、令人厌恶的状态，而不仅仅是表面上的脏。

让我们来看一些例句：

• Dirty: My hands are dirty after playing in the garden. (我的手在花园里玩耍后脏了。) This is a relatively mild statement, simply stating a fact.

• Filthy: The room was filthy; it hadn't been cleaned for weeks. (房间脏得令人作呕；好几个星期都没打扫了。) This sentence implies a much higher degree of dirtiness and suggests neglect.

再来看一些其他例子：

• Dirty: The car is dirty, I need to wash it. (车子脏了，我需要洗洗。) This is a simple observation.

• Filthy: The dishes were filthy with dried food and grease. (盘子脏得油腻腻的，上面还粘着干了的饭菜。) This emphasizes the unpleasant and disgusting aspect of the dirt.

另一个区别在于，"filthy" 可以用来形容不只是物质上的脏，还可以形容语言、想法等方面的不洁净。例如：

• Filthy: He told a filthy joke. (他讲了一个下流的玩笑。) Here, "filthy" refers to the moral offensiveness of the joke, not its physical state.

因此，选择哪个词取决于你想表达的脏的程度和性质。如果只是普通的脏，用“dirty”即可；如果想强调脏得令人反感，甚至恶心，那就用“filthy”。
