Fill in the gaps with the correct form of the verbs in brackets. Use the FULL form.

Let's fill in the gaps with the correct forms of the verbs in brackets, using the FULL form as requested. A: You look worried. What **is happening**? *Explanation:* Since the speaker sees someone looking worried now (present continuous), the question refers to something that is happening at the moment. Therefore, we use the present continuous tense. The full form is "is happening". B: I **did not pay** pay the bills last month. *Explanation:* The sentence indicates an action that did not happen in the past ("last month"). We use the past simple negative form here. The full form of the negative past simple of "pay" is "did not pay". **Translation into Russian:** A: Ты выглядишь обеспокоенным. Что происходит? B: Я не оплатил счета в прошлом месяце.
