Choose the correct variant. We usually ... to school by bus.

Grammar Rule: The Present Simple tense is used for habits, routines, and general truths.

The sentence describes a usual activity, which is a habit or a routine. Therefore, the Present Simple tense is appropriate.

The subject is 'We', which is plural. For plural subjects in the Present Simple, the base form of the verb is used.

Let's analyze the options:

• 'go' - This is the base form of the verb, suitable for plural subjects in the Present Simple.
• 'are going' - This is the Present Continuous tense, used for actions happening now.
• 'have gone' - This is the Present Perfect tense, used for actions with a connection to the present but not necessarily a routine.
• 'have been going' - This is the Present Perfect Continuous tense, used for actions that started in the past and continue up to the present, often emphasizing duration.
• 'goes' - This is the third-person singular form of the verb, used for singular subjects (he, she, it).

The correct choice for 'We usually ... to school by bus.' is 'go'.
