To make negative sentences in the Present Simple for ‘he’, ‘she’, and ‘it’, you always use doesn’t followed by the base form of the verb. This means you do not add ‘-s’ to the main verb. For example, you say He doesn’t work here, 而不是 He doesn’t works here. The word doesn’t is a short form of does not. It helps us show that the action is not happening or is not true for a singular third-person subject. Remember this simple structure to speak and write correctly about what ‘he’, ‘she’, or ‘it’ does not do.
What is the Present Simple Negative for He, She, It?
The Present Simple is for actions that happen regularly or for facts. When we want to say that something is NOT true or NOT happening for ‘he’, ‘she’, or ‘it’, we use the negative form.
- 我们使用 doesn’t to make the verb negative.
- Doesn’t is the short form of does not.
- After doesn’t, the main verb always stays in its base form (the infinitive without ‘to’).
How Do We Form Negative Sentences?
The structure for negative sentences with 'he', 'she', and 'it' is very simple:
- Subject + doesn't + Base Form of the Verb
For example, if you want to say that a person does not like coffee, you would say:
- She doesn't like coffee.
It is important to remember that doesn't is only for 'he', 'she', and 'it'. For 'I', 'you', 'we', and 'they', we use don't.
Remember: No '-s' on the Main Verb!
This is a very common mistake for learners. When you use doesn't, the main verb does NOT get an '-s' at the end.
这个词 does already shows that the subject is 'he', 'she', or 'it'. So, you do not need to add '-s' to the next verb.
- 正确： He doesn't play football.
- 错误： He doesn't plays football.
示例
- He doesn't live in London.
- She doesn't speak French.
- It doesn't rain much in summer here.
- My brother doesn't work on Sundays.
- The cat doesn't eat fish.
- He doesn't like fast food.

西班牙语母语者常犯的错误
Many Spanish speakers make two common mistakes when forming negative sentences with 'he', 'she', 'it' in the Present Simple:
- Using 'no' directly before the verb: In Spanish, you might say Él no trabaja. But in English, you cannot say He no works. You must use doesn't. The correct form is He doesn't work.
- Adding '-s' to the main verb after 'doesn't': This is a very common error. You might think, 'It's 'he', so the verb needs an '-s'.' But does already has the '-s' form. So, you should say She doesn't like, 而不是 She doesn't likes.
