1. On Saturday he sometimes goes to the cinema. (Choose: Present Simple or Present Continuous)

Answer: The correct answer is "1) On Saturday he sometimes goes to the cinema." We use the Present Simple tense to talk about habitual actions or regular activities. In this sentence, the action of going to the cinema on Saturdays is a habitual action.

2. She is calling him. (Make a sentence in Present Continuous)

Answer: The correct answer is "3) She is calling him." We use the Present Continuous tense to talk about actions happening at the moment of speaking or actions that are temporary. In this sentence, the action of calling is happening at the moment of speaking.

3. It hasn’t stopped raining. (Make a negative sentence in the Present Perfect)

Answer: The correct answer is "1) It hasn’t stopped raining." We use "hasn't" to make a negative sentence in the Present Perfect tense. In this sentence, the action of raining started in the past and is still continuing.

4. If we knew about his plans, we wouldn’t hire him. (Choose the correct form)

Answer: The correct answer is "1) Knew." We use the past simple tense in the conditional clause to talk about a hypothetical situation or something that is contrary to fact. In this sentence, the condition is not knowing about his plans, which is in the past, so we use the past simple tense "knew."
