Should and Shouldn't Exercises

Should and shouldn't are modal verbs used for advice, recommendations, and opinions about the right thing to do. "You should eat more vegetables" gives friendly advice. "You shouldn't stay up so late" recommends against an action. Unlike must (which expresses strong obligation or prohibition), should is softer — it suggests what is a good idea, not what is required. The person is free to choose.

Should is also used for expectations based on logic or plans: "The bus should arrive in ten minutes" (I expect it will based on the timetable). The structure is simple: should / shouldn't + base verb, with no changes for third person (he should, she should, it should — no "s"). Questions are formed by putting "should" before the subject: "Should I call the doctor?" For past regrets or criticism, use "should have" + past participle: "You should have told me earlier" (but you didn't). The word "ought to" has the same meaning as "should" but is less common in everyday English.
