Practice Forming The Future Tense

The future tense has several forms in English. The two main forms are:

• will+ (base form of) verb,
• be + going to + verb

In casual conversation we also use be + going without a verb, especially when we are talking about the near future.  (An example would be “He’s going to the fair next week.”)

We sometimes talk about the future using plan, hope, want, or need with another verb infinitive:

• I plan to go.

• He wants to study at MIT.

• You need to get better grades!
