Format of English paper titles

The format of English paper titles is as follows:

There are three ways to write the title of an English paper. ? The first one is the ":"that your teacher said, with the colon on the left as the main title and the colon on the right as the subtitle. This is a relatively standardized title format and the most widely used format. For example: hand and heart: what information does the gesture reveal about the mind?

The second word is dash. In fact, in recent years, with the great cultural integration, some habits of China and the West are infiltrating each other. However, the dash in English is different from the traditional writing method in China. Generally, you don't need to start a new line, but follow it directly. For example: Challenger-a lesson for the future?

The third is semantic cohesion, and the most common one is question and answer. For example: What is Africa to me? Language, Ideology and African Americans
