Answer:
1. Concentrate on your work so you will do it properly.
2. These men risk their lives so that we can live safely.
3. Team of rescue workers arrived at the spot in order to save those involved in the accident.
Step-by-step explanation:
We completed the sentences above with "so", "so that", and "in order to", which are some conjunctions of purpose. Other examples of such conjunctions are "to", and "so as to". The function of these conjunctions is to create a relationship of purpose in a sentence, connecting two ideas. One idea is the goal, the purpose of the other. Let's use one of the sentences above as an example:
3. Team of rescue workers arrived at the spot in order to save those involved in the accident.
What is the purpose of the team of rescue workers arriving? It is to save those involved in the accident. To indicate that, we connected the two ideas with "in order to".
