Question

I wish I could __________

• A. working on weekends.
• B. worked on weekends.
• C. work on weekends.
• D. works on weekends.

Answer 1

Answer:

C. work on weekends.

After the modal auxiliary “could”, we use the base form (V₁) of the verb.

👉 could + V₁ → could work

• working on weekends ❌ — could is not followed directly by V-ing.

• worked on weekends ❌ — could takes the base form, not the past form.

• work on weekends ✅ — correct base form after could.

• works on weekends ❌ — works is a third-person singular form and cannot follow could.

Rule:
Modal auxiliary + V₁

Examples:

• I could help you.

• She could come tomorrow.

• They could finish the work.
