 10 kg = 1 yến                                                                   8 yến = 80 kg

1. I usually use my computer

2. I'm online for about 1, 2 hours

3. I prefer a laptop because it's quite convenient

4. I use my computer to study online, listen to music, watch movies and sometimes I even read stories online!

5. I think it's very important to learn how to use a computer, especially in an era where the technology industry is developing like now.
