Use the Simple Present tense to state facts, general truths, or actions that happen regularly. Remember that plural subjects take the base form of the verb (e.g., "they go," "stars shine").
Step 1: Analyze the subject and the action. The subject is 'Stars' (plural). The sentence describes a general truth or a habitual action that happens repeatedly.
Step 2: Determine the correct verb tense. For general truths or habitual actions, the Simple Present tense is used.
Step 3: Select the correct verb form for a plural subject. In the Simple Present tense, a plural subject takes the base form of the verb (without '-s').
Step 4: Apply the correct form. The correct verb is 'shine'. The sentence is: "Stars shine all night."
