ing和ed的区别
The main difference is that –ing adjectives are usually used to talk about the person, place or thing that is making us feel a certain way:
- Yawn! This lecture is really boring!
But –ed adjectives are used to talk about how we feel:
- I’ve been listening to him for hours – I’m so bored.
Be careful: If you say I am boring – it’s grammatically correct, but it means that you make other people feel bored!
