Review Questions

• How does the use of 'could' differ when expressing past ability versus hypothetical situations?
  • 'Could' indicates past ability when used to describe something someone was capable of doing before, such as 'I could ride a bike when I was younger.' In contrast, when discussing hypothetical situations, 'could' suggests potential outcomes that depend on certain conditions being met. For example, in a sentence like 'If I studied harder, I could pass the exam,' it illustrates a possibility rather than a certainty.
• In what ways does 'could' function within the subjunctive mood and conditional sentences?
  • 'Could' functions within conditional sentences to indicate possibilities based on certain conditions. For instance, in a sentence like 'If he practiced more, he could improve,' it highlights a future possibility contingent on the condition. In the subjunctive mood, although it doesn’t directly appear as a subjunctive form, it conveys similar hypothetical meanings through sentences like 'If I were rich, I could travel the world,' expressing an unreal condition.
• Evaluate how using 'could' in polite requests impacts communication style and social interactions.
  • 'Could' enhances politeness in requests by softening the command and making it sound less imposing. For example, asking 'Could you help me with my homework?' is more courteous than saying 'Help me with my homework.' This subtlety fosters positive social interactions by promoting consideration and respect for others’ autonomy. In various cultures and settings, such polite phrasing can influence how requests are received and whether individuals feel comfortable responding affirmatively.
