1. "Please fasten your seat for take-off."

This sentence is an instruction given to passengers before a plane takes off. It is a safety measure to ensure that everyone is securely fastened in their seats during the potentially turbulent take-off process.

Explanation: When an airplane is preparing to take off, the flight attendants will typically make an announcement requesting all passengers to fasten their seat belts. This is because take-offs can be bumpy and it's important for passengers to be seated and secured to prevent any injuries or accidents during this phase of the flight.

Step-by-step solution:
- Find your seat on the airplane.
- Locate the seat belt, which is usually found on the side of the seat or attached to the seat itself.
- Take one end of the seat belt and insert it into the buckle on the other end.
- Pull the loose end of the seat belt to tighten it around your waist.
- Make sure the seat belt is snug and secure, but not too tight.
- Listen to any further instructions from the flight attendants or pilot.

2. "Our plane is delayed and we've been waiting in this security lounge for hours!"

This sentence expresses frustration and annoyance about a delay in the flight schedule, resulting in an extended waiting time in the security lounge of the airport.

Explanation: Sometimes, due to various reasons such as weather conditions, technical difficulties, or air traffic congestion, flights may experience delays. Passengers are often required to wait in designated areas, such as the security lounge, until the plane is ready for departure.

Step-by-step solution:
- Check the departure board or listen for announcements to stay updated with the latest information regarding your flight.
- If you notice that your flight is delayed, find a comfortable seat in the security lounge or utilize any facilities available.
- Use the extra time to read a book, play games on your electronic device, chat with fellow passengers, or engage in any other activity to pass the time.
- Keep track of any new announcements or updates from the airline or airport staff regarding the status of your flight.
- Remain patient and understanding, as delays are often unavoidable and the airline is working to ensure your safety and provide a smooth travel experience.

3. "The GPS said, 'Turn left here. You have caught your destination.'"

This sentence indicates that the Global Positioning System (GPS) device or application is instructing the user to make a left turn and that they have reached their intended destination.

Explanation: GPS is a navigation system that uses satellite signals to provide users with accurate positioning and directions. It assists individuals in finding their way to a specific location by giving turn-by-turn instructions and displaying maps.

Step-by-step solution:
- Use a GPS device or a GPS-enabled smartphone application to input your desired destination.
- Follow the instructions provided by the GPS, which often include turn-by-turn directions.
- When the GPS notifies you to "turn left here," look for appropriate signage, road markings, or landmarks indicating the required left turn.
- Slow down your vehicle and safely make the left turn, ensuring that you are complying with all traffic laws and regulations.
- Continue following the GPS instructions until it indicates that you have arrived at your destination.

4. "Can we go out on holiday for a week in the summer?"

This sentence is a request or inquiry about the possibility of going on vacation for a week during the summer season.

Explanation: Many people have holidays or breaks during the summer months and may want to plan a vacation or leisure activities during that time. It is common to seek permission or make arrangements in advance for such plans, especially for school students who have a defined academic calendar.

Step-by-step solution:
- Determine the exact dates you would like to go on holiday.
- Request permission from your parents or guardians, as they will need to be aware of and approve your plans.
- If you are a student, check your school's academic calendar to see if the proposed dates conflict with any important events or exams.
- Have a discussion with your family or whoever is responsible for your vacation plans, considering factors such as budget, availability of accommodations, and any other commitments during that time.
- If it is feasible, make the necessary arrangements, such as booking flights or accommodations, and ensure you have all the necessary documents, such as passports or visas, if required.

Please note that these step-by-step solutions are general guidelines and the specific steps may vary depending on the situation or individual circumstances.
