How is the future tense formed in English?

In English, the future tense is formed with the auxiliary verb "will" or "shall" followed by the base form of the main verb. For example, "I will go" or "I shall go." Another way to express the future tense in English is to use the present tense of the verb "to be" followed by the present participle of the main verb. This is known as the "be going to" construction, and it is used to express plans or intentions. For example, "I am going to go." Additionally, the future tense can be formed using the present tense, or base form of verb to indicate a scheduled event in the future, like "The train leaves at 4 PM." The Future Continuous Tense, which indicate an action that will be in progress at a specific time in the future, formed by using will/shall + be + verb + -ing, like "I will be studying at 8 PM." The Future Perfect Tense, which indicate an action that will have completed at a specific point in the future, formed by using will/shall + have + verb in past participle form, like "I will have finished my work by the evening."
