Put the verbs in brackets into the correct tense.
1 If I ... (get) lost in a forest, l'd be scared.
2 If I were you, I ... (take) lots of water with me.
3 If he'd known, he ... (not/go) there.
4 I wish I ... (take) my GPS. I wouldn't have got lost.
5 Unless they work hard, they... (not/succeed).
6. I wish I ... (not/hurt) my knee. I can't walk.
7 What ... (you/do) if you saw a snake?
8 If it ... (snow), we won't go hiking.
Explanation: In this case, we are talking about a hypothetical situation in the present. The speaker is imagining what would happen if they were to get lost in a forest. "If I got" is the correct tense, using the simple past form of the verb "get".
2. If I were you, I would take lots of water with me.
Explanation: "If I were you" is an example of a conditional sentence called the second conditional. We use the past simple tense "were" for the verb "to be" in these types of sentences. The speaker is giving advice to someone else, saying what they would do in their position.
3. If he had known, he would not have gone there.
Explanation: Here, we are again using the second conditional structure. "If he had known" refers to a past unreal situation, and we use the past perfect tense "had known" to indicate that the action happened before the other action. "He would not have gone" is the result of the unreal situation.
4. I wish I had taken my GPS. I wouldn't have gotten lost.
Explanation: Here, we use the past perfect tense "had taken" to indicate that the action should have happened before another past action. "I wouldn't have gotten lost" is the result of not taking the GPS. The speaker expresses regret for not taking the GPS and states the consequence of that decision.
5. Unless they work hard, they will not succeed.
Explanation: "Unless" is used to express a condition indicating that if something does not happen, the result will not happen either. In this case, the speaker is saying that if they do not work hard, they will not succeed. "They will not succeed" is in the simple future tense, indicating a possible outcome in the future.
6. I wish I hadn't hurt my knee. I can't walk.
Explanation: "I wish I hadn't hurt" is the past perfect tense used to express regret for something that happened in the past. The speaker regrets hurting their knee and states the consequence of that action, which is the inability to walk.
7. What would you do if you saw a snake?
Explanation: "What would you do" is an example of the second conditional structure. We use the simple past tense "saw" to indicate the unreal situation, imagining what the person would do if they saw a snake.
8. If it snows, we won't go hiking.
Explanation: Here, we use the present simple tense "snows" to indicate a possible future condition. The speaker is stating that if it snows, they will not go hiking.
