Cách sử dụng
The word 'not' is used to make sentences negative or to express the opposite meaning. It is usually placed after a helping verb such as 'am', 'is', 'are', 'was', 'were', 'has', 'have', 'had', 'will', 'would', 'can', 'could', 'should', 'may', or 'might'. For example, "I am not happy" means that I am not feeling happy. It can also be used before a verb to mean the same thing. For example, "I do not like pizza" means that I don't have a positive feeling towards pizza. It is important to use 'not' appropriately to avoid conveying the wrong meaning.
