1. Mary has worked overtime every day this week, as it’s the busiest time in the company.

Explanation: The word "overtime" indicates that Mary has been working additional hours beyond the normal working hours. We use the present perfect tense "has worked" to show that the action started in the past and continues up until the present moment.

2. What I like about working as a freelancer is that I don’t have to stay in the office.

Explanation: A freelancer is a person who works on a project basis without being employed by a specific company. We use "a freelancer" to talk about someone's profession, and "working" to show that it is their current activity.

3. Her husband got a new job in the other city, so they had to move there.

Explanation: "Move" means to change one's residence or location. In this sentence, it indicates that the couple needed to relocate to the other city due to her husband's new job opportunity. We use "had to" to show that it was necessary for them to move.

4. The animals landed safe and sound before the eyes of a huge crowd.

Explanation: "Safe and sound" is an idiom used to indicate that something or someone is safe and unharmed. In this sentence, it describes how the animals landed without any harm. We use "landed" to show the action of the animals' descent.

5. As his father is a military man, John has to change schools quite often.

Explanation: "Change" means to move from one thing to another. In this context, it means that John needs to switch schools frequently because his father's military profession requires them to relocate frequently. We use "has to" to express obligation or necessity.

6. Soon the brothers came to the conclusion that it was heat but not smoke that lifted things.

Explanation: "Come to the conclusion" is a phrase used to say that someone has reached a decision or formed an opinion after considering all the information. In this sentence, it means that the brothers understood that it was heat, not smoke, that caused things to rise. We use "came" to show the action of reaching a conclusion.
