Hello class! Good morning everyone!
Today, we will be practicing our English grammar, focusing on different tenses. Please pay close attention to the explanations and examples. Let’s get started!
Exercise 1: Fill in the blanks with the correct form of the verbs in parentheses.
1. Be quiet! The baby (sleep).
Explanation: This is an action happening right now, at this very moment. So, we use the Present Continuous tense.
Answer: Be quiet! The baby is sleeping.
2. Water (boil) at 100 degrees Celsius.
Explanation: This is a general truth, a scientific fact. We use the Present Simple tense for facts and general truths.
Answer: Water boils at 100 degrees Celsius.
3. My creative brother always (forget) his keys. It’s so annoying!
Explanation: The word “always” indicates a habit or a repeated action. We use the Present Simple tense for habits and routines.
Answer: My creative brother always forgets his keys. It’s so annoying!
4. What (you/do) under the table right now?
Explanation: The phrase “right now” tells us that the action is happening at this moment. We use the Present Continuous tense.
Answer: What are you doing under the table right now?
5. I (not/own) a car, so I go to work by bus.
Explanation: This sentence describes a current state or possession. “Not/own” is a negative verb describing a state, so we use the Present Simple tense.
Answer: I do not own a car, so I go to work by bus.
6. I (walk) down the street when I (meet) an old friend.
Explanation: This describes two actions in the past. One action (“walk”) was ongoing when another action (“meet”) interrupted it. The ongoing action uses the Past Continuous, and the interrupting action uses the Past Simple.
Answer: I was walking down the street when I met an old friend.
7. Yesterday at this time, we (sit) on the beach.
Explanation: “Yesterday at this time” refers to a specific point in time in the past when an action was in progress. We use the Past Continuous tense.
Answer: Yesterday at this time, we were sitting on the beach.
8. Shakespeare (write) many famous plays, including Hamlet.
Explanation: This is a statement about a historical figure and their completed achievements in the past. We use the Past Simple tense.
Answer: Shakespeare wrote many famous plays, including Hamlet.
9. While my mom (wash) the dishes, my dad (read) a newspaper.
Explanation: Both actions were happening at the same time in the past and were ongoing. We use the Past Continuous tense for both verbs.
Answer: While my mom was washing the dishes, my dad was reading a newspaper.
10. The power (go) out while we (have) dinner.
Explanation: Similar to sentence 6, one action (“have dinner”) was ongoing when another action (“go out”) interrupted it. The ongoing action uses the Past Continuous, and the interrupting action uses the Past Simple.
Answer: The power went out while we were having dinner.
11. I (live) in this city for 10 years, and I still live here now.
Explanation: This sentence describes an action that started in the past and continues up to the present moment. We use the Present Perfect Continuous tense (or Present Perfect Simple for states). Since it emphasizes the duration, Present Perfect Continuous is a good choice.
Answer: I have been living in this city for 10 years, and I still live here now.
12. I (live) in Paris for 2 years when I was a child.
Explanation: This refers to a completed period of time in the past (“when I was a child”). We use the Past Simple tense.
Answer: I lived in Paris for 2 years when I was a child.
13. (you/ever/visit) London?
Explanation: This question asks about an experience at any point in someone’s life up to the present. We use the Present Perfect tense.
Answer: Have you ever visited London?
14. She (already/finish) her homework, so she can go out.
Explanation: The word “already” indicates that an action has been completed before the present moment, and this completion has a result now. We use the Present Perfect tense.
Answer: She has already finished her homework, so she can go out.
15. He (lose) his key yesterday and he still can’t find it.
Explanation: The action of losing the key happened “yesterday,” which is a specific time in the past. Even though he still can’t find it, the losing event is in the past. We use the Past Simple tense.
Answer: He lost his key yesterday and he still can’t find it.
16. Your eyes are red. (you/cry)?
Explanation: The red eyes are a present result of an action that has just happened. We use the Present Perfect Continuous tense to show an action that has just finished and has a present result.
Answer: Your eyes are red. Have you been crying?
17. I (study) English for 3 hours and my head is spinning!
Explanation: This describes an action that started in the past (“for 3 hours”) and is still continuing, or has just finished and has a present effect (spinning head). The Present Perfect Continuous tense is appropriate here.
Answer: I have been studying English for 3 hours and my head is spinning!
18. When we got to the station, the train (already/leave).
Explanation: Both actions happened in the past. The train leaving happened before we got to the station. We use the Past Perfect tense for the earlier action.
Answer: When we got to the station, the train had already left.
19. By the time he turned 25, he (write) two books.
Explanation: “By the time he turned 25” refers to a point in the past. The action of writing the books happened before that point. We use the Past Perfect tense.
Answer: By the time he turned 25, he had written two books.
20. If it (not/rain) tomorrow, we will go camping
Explanation: This is a First Conditional sentence. It talks about a possible future condition and its likely result. The “if” clause uses the Present Simple tense.
Answer: If it does not rain tomorrow, we will go camping.
