In the future, I want to live in a smart house located near the beach, where I can enjoy both nature and modern technology. My smart house will have voice-controlled lights, automatic doors, a smart fridge, and a home security system with AI cameras. It will also include a smart assistant that can help manage daily tasks like turning on appliances, reminding me of appointments, or even ordering groceries. The main advantage is that it saves time and makes life more comfortable. However, a disadvantage is that it depends on electricity and internet connection, which could cause problems during outages. I want to live there with my family, so we can enjoy a relaxing and convenient life together. I dream of this house because it combines comfort, safety, and technology in a peaceful place.

One smart technology device that will be widely used in the near future is the Smart Traffic Control System. This machine is applied in the field of transportation, and it is expected to become common between 2025 and 2030. It works by using sensors, cameras, and artificial intelligence to monitor traffic in real time. The system can automatically change traffic light patterns and provide the best driving routes for vehicles. This operation helps to reduce traffic jams, save fuel, and cut down on air pollution. It also improves road safety by warning drivers about accidents or dangerous situations ahead. Overall, this technology brings great benefits by making transportation faster, safer, and more eco-friendly. It offers an effective solution to one of the biggest problems in modern cities: traffic congestion.

One eco-friendly machine that helps protect the environment is the solar-powered water pump. It looks simple, but it’s actually a smart and useful machine. It uses clean energy from the sun to help bring water where it’s needed. This type of energy is chosen because it is safe, abundant, and doesn’t create pollution. It’s especially helpful in sunny countries like Vietnam. The system has four main parts: the solar panel, the controller, the electric motor, and the pump. First, the solar panel takes sunlight and turns it into electricity. This electricity is clean and does not create pollution. But because sunlight changes during the day, the system needs a controller. The controller helps manage the electricity — making sure the power stays stable and safe. Then, the motor uses the electricity to run the pump. The pump pulls water from a well, river, lake, or tank and sends it to where it’s needed — like farms, houses, or storage tanks.

The system works automatically during the day and needs little care. One problem is that it doesn’t work well on cloudy or rainy days.

Now, I am going to tell you some activities that we can do to save the planet Earth. First of all, as a mechanical engineering student, I can help protect the Earth by living a more eco-friendly life. In my daily routine, I can save energy by turning off lights when not in use, using public transport, and recycling plastic or paper. Furthermore, I can talk to my friends and family about protecting the environment. In the future, when I work as an engineer, I will try to design machines that use clean energy like solar or wind. Besides, I can help make machines that use less electricity and produce less pollution. Last but not least, I want to learn more about green technology so I can help create better solutions for our planet. Even small actions matter, and engineers like us can make a big difference.

In the future, I want to work as a mechanical design engineer at a company that focuses on technology and innovation. I would like to join a company like VinFast or Thaco because they work in the automotive field and use modern machines. These companies often offer good benefits such as a stable salary, health insurance, and training programs. I think these are very helpful for young engineers.

Besides that, I would like to have flexible working hours and support for further education like master’s degrees or technical courses. It would be great if the company also had team-building trips or sports activities.

The benefit I prefer the most is training and learning support. I want to improve my skills and grow in my career, so learning chances are very important to me.

Dear Mr.Tu

I have just graduated in Mechanical Engineering. I can use design software like NX, SolidWorks, and Geomagic Design X. I also know how to do sheet metal simulation in AutoForm. I joined many school projects about reverse engineering and mold design. These helped me learn how to solve problems and work well in a team. I am also doing research about making car parts.

In the next five years, I want to become a skilled design engineer and join new product development. I know your company uses modern technology and works on exciting projects. That’s why I want to apply for the junior mechanical design engineer position. I believe my skills, willingness to learn, and love for design make me a good fit.Thank you for taking the time to read my application. I hope to have the chance to work with your team.

Yours sincerely

Duy Vu

Dear Mr. Tu,

I am writing to apply for the position of Junior Mechanical Engineer, which was advertised on your website – abc.com. The job description matches my skills and experience, especially in the field of reverse engineering.

I am currently pursuing a Bachelor's degree in Mechanical Engineering at Hanoi University of Industry and will graduate in 2026. Although I have not yet graduated, I am confident in my knowledge of reverse engineering, 3D modeling, and CAD software such as SolidWorks and Geomagic.

I have participated in and completed several reverse engineering and 3D scanning projects at the university’s Research Center. These projects have given me hands-on experience in turning real objects into accurate 3D models.

I am hard-working, eager to learn, and highly interested in this position. Thank you for considering my application.

Yours sincerely,
Nguyen Duy Vu

Dear Mr.Tu

I hope you’re well. I’m writing to kindly request an advance payment due to an unexpected financial difficulty. Recently, my wife gave birth unexpectedly earlier than planned, and I was not financially prepared for the hospital and baby-related expenses.

Because of this, I would like to request an advance payment of $1,000 to help cover these urgent costs. I understand the responsibilities that come with this, and I am willing to support the team in any way I can during this time.

Thank you very much for understanding and for considering my request.

Yours sincerely

Now, I am going to tell you about how to use a machine I like the most that is ABC cordless hammer drill. It stands out with its compact design and lightweight construction, weighing only 3.6 pounds. Additionally, the drill is equipped with advanced features such as a 20-volt battery, a brushless motor, and a two-speed transmission, which improve efficiency and performance. The ABC cordless hammer drill is designed to creae holes in various materials and work in tight space. Operating this machine is very easy. There are two stage but today we are focus into stage 2: Drilling safely. After preparing to drill, you should drill a pilot hole. It will help prevent your drill bit from slipping. Next step, Hold the drill steady and push it in to the material you’re drilling. The third step, Each drill has a twistable collar to adjust the torque, often with a series of numbers on it and Remember to not touch the drill bit because it is overheating, it can be damaged your hand. That’s so. I hope some information about how to use a ABC cordless hammer drill that will help you work better.
