What's the difference between or and in English?

In English, "or" and "are two commonly used conjunctions, which connect different parts in sentences. Although they are all used to connect words, phrases or sentences, there are some important differences between them.

In addition, or and can also be used in negative sentences. In negative sentences, "or" means exclusive relationship, and "and" means inclusive relationship. I don't know.

In addition, or and can also be used in conditional sentences. In conditional sentences, "or" means optional condition, and "and" means necessary and sufficient condition. For example, if it rains, we will stay at home or go to the movies. In this example, we can choose to stay at home or go to the movies. On the contrary, if we say, "If there is a train, we will stay at home and watch TV." If it rains, we will stay at home and watch TV. ), indicating that you can only watch TV at home.

In short, "or" and "and" have different usages and meanings in English. "or" indicates the selection relationship and connects mutually exclusive options; "And" means a parallel relationship connecting similar or related options. In addition, they can also be used in negative sentences and conditional sentences, indicating exclusion relationship and necessary and sufficient conditions respectively. Therefore, when using these two conjunctions, we need to choose the appropriate conjunctions according to the specific context to ensure the accurate transmission of the meaning of the sentence.
