---

Exercise: Fill in the blanks with the correct modal verb from the options given.

---

#### 1. It ________ rain tonight. (may/might)
✔ Answer: may / might
Both are correct here. "May" and "might" both express possibility.
👉 *"It may rain tonight."* or *"It might rain tonight."* — both are grammatically correct.
Note: "Might" is slightly more tentative than "may".

---

#### 2. You ________ go now. (can/could)
✔ Answer: can
"Can" is used for permission or ability in present/future contexts.
👉 *"You can go now."* — this is a direct permission.
"Could" is more polite but less common for immediate permission unless being formal.
So, "can" is best here.

---

#### 3. ________ you live long! (may/might)
✔ Answer: May
This is a wish or blessing.
👉 *"May you live long!"* — this is a traditional expression.
"May" is used for wishes, not "might".
✘ "Might you live long?" — sounds unnatural.

---

#### 4. He ________ lift the box. (can/could)
✔ Answer: can
This refers to present ability.
👉 *"He can lift the box."* — he has the strength now.
"Could" would imply past ability or a hypothetical situation.

---

#### 5. I ________ punish you. (will/shall)
✔ Answer: shall
"Shall" is used for future actions when expressing a promise, threat, or intention (especially in formal English).
👉 *"I shall punish you."* — implies a firm decision.
"Will" is also possible in modern usage, but "shall" is more appropriate here in formal tone.

> Note: In British English, "shall" is used for future tense in first person (I/We), while "will" is for second/third person.

But since it's a threat, "shall" fits better.

---

#### 6. We eat so that we ________ live. (may/might)
✔ Answer: may
"May" expresses purpose or intention.
👉 *"We eat so that we may live."* — indicates purpose.
"May" is used here to show purpose or desire.
"Might" would be too uncertain.

---

#### 7. I ________ not come yesterday. (can/could)
✔ Answer: could
This refers to past ability or possibility.
👉 *"I could not come yesterday."* — I was unable to come.
"Can" is present tense; "could" is past tense.

---

#### 8. You ________ leave the room at once. (will/shall)
✔ Answer: shall
This is an order or command.
👉 *"You shall leave the room at once."* — "Shall" is used for commands, rules, or obligations.
"Will" is more about willingness or future prediction.

---

#### 9. Everyone ________ make a mistake. (can/could)
✔ Answer: can
"Can" expresses possibility in general.
👉 *"Everyone can make a mistake."* — it’s a general truth.
"Could" would suggest hypothetical or less likely situations.

---

#### 10. He hoped that he ________ pass the test. (would/should)
✔ Answer: would
This is a past hope about a future event.
👉 *"He hoped that he would pass the test."* — "would" refers to future action from his perspective in the past.
"Should" would imply expectation or obligation, not the intended meaning here.
