1. My dad has the best computer in our house.

2. My laptop is the lightest one you can buy.

3. The most popular website among my friends in YouTube.

4. This smartphone has the biggest screen of all the ones in the shop. Do you like it?

5. The most bad thing about my computer is the mouse. It doesn't work properly.

6. My mum's phone is the oldest one in our family.

Хорошего дня! :)
