1) If I see Tom, I will tell him the news.
To rewrite the sentence using the first conditional, we need to use "if" followed by the present simple tense (do/does) and the future simple tense (will + base verb). In this case, the first part of the sentence "I see Tom" is in the present simple tense, so we need to use "will tell" for the second part.
2) If you wait for me, I will go to the market with you.
Again, we use "if" followed by the present simple tense and the future simple tense. In this case, the first part "You wait for me" is already in the present simple tense, so we just need to use "will go" for the second part.
3) If we had a yacht, we would sail around the world.
To rewrite the sentence using the second conditional, we need to use "if" followed by the past simple tense and the would + base verb. In this case, the first part "We have a yacht" is in the present simple tense, so we need to use "had" for the second part.
4) If your room were tidy, you wouldn't look for your things.
Using the second conditional again, we need to use "if" followed by the past simple tense and the would + base verb. However, for the second part, we need to use the negative form "wouldn't look" because the original sentence says "You don't look for your things."
5) As soon as they watch TV, she cleans the flat.
To rewrite the sentence using the first conditional, we need to use "if" or "when" instead of "as soon as" and use the present simple tense for both parts. In this case, we can use "When they watch TV, she cleans the flat."
6) If children don't play with matches, a fire doesn't break out.
Using the second conditional, we can rewrite the sentence using "if" followed by the present simple tense and the present simple tense for both parts. Since the original sentence says "A fire doesn't break out" in the second part, we keep it the same.
7) Unless he reads your e-mail letter, he won't turn on his computer.
To rewrite the sentence using the first conditional and "unless," we need to use "if" and the present simple tense for the first part, and the negative form of the future simple tense (won't + base verb) for the second part.
8) If we helped her, she would tell the truth.
Using the second conditional, we use "if" followed by the past simple tense and the would + base verb. In this case, the first part "We help her" is in the present simple tense, so we need to use "helped" for the second part.
9) When they play a game of chess, father returns home.
To rewrite the sentence using the first conditional and "when," we can use "When they play a game of chess, father will return home." Both parts use the present simple tense.
10) If the train doesn't arrive later, we won't meet you here.
Using the second conditional, we can rewrite the sentence using "if" followed by the present simple tense and the negative form of the future simple tense (won't + base verb) for both parts.
Explanation:
In this sentence, we are talking about a planned event that will happen in the future. The verb "to arrive" is in the infinitive form. To talk about future events, we use the Future Simple tense. In the Future Simple tense, we use the auxiliary verb "will" followed by the base form of the main verb.
Step-by-step solution:
1. Identify the verb: The verb in this sentence is "to arrive."
2. Determine the tense: In this case, we need to use the Future Simple tense because we are talking about a future event.
3. Construct the sentence: To form the Future Simple tense, we use the auxiliary verb "will" followed by the base form of the main verb. Therefore, the sentence becomes "The train will arrive at 12:30."
Additional notes:
The Future Simple tense is commonly used to talk about events that have been planned or scheduled to happen in the future. It is important to note that the Future Simple tense is not used for actions that are spontaneous or decisions made at the moment of speaking.
