Szia! Szerintem/Nekem az egyes a legkönnyebb, remélem jó lesz:

The one thing I can never live without is my phone. In the 21st century, this device can be used for everything. To pay the bills, order from a website, get and stay in touch with others and search for information about anything you can imagine. It's needed for school as well, especially since we have learned online. I can communicate with my teachers and classmates, and look for statistics for my projects. In my free time, it's easy to play some games or watch a film on it. It's always in my pocket or bag, so I can take some pictures with it whenever I need to or I feel like it. It's an opportunity to ask for help quickly, I just have to put the right number in depending on who I want to call. In some situations, it can save lives, but we have to be cautious with it. It's harmful to use it a lot and we should not give out our personal information such as passwords, card numbers and our addresses because these can be easily stolen.
