4. Work in groups. Write tips for one of the following situations
Gợi ý trả lời:
Situation 1: A friend of yours cannot get a good night's sleep.
Go to bed and wake up at the same time every day, even on weekends. This helps your body develop a natural sleep pattern. Avoid using your phone or computer at least 30 minutes before bedtime because the blue light can keep you awake.
Situation 2: A friend of yours does not feel very well.
When you don't feel well, your body needs time to recover. Try to get at least 8-9 hours of sleep each night. Take short naps during the day if you feel tired, but don't sleep too much during daytime as it might affect your night sleep.
Situation 3: A friend of yours cannot remember the words he/she learnt.
Don't just read the words - write them down several times, say them out loud, and use them in sentences. Make flashcards with the word on one side and the meaning on the other. The more ways you practice, the better you'll remember.

Gợi ý trả lời:
I talked with Nam about how he manages a well-balanced life. First, regarding time management, Nam believes that making a schedule is essential. He creates a weekly plan where he lists all his tasks and gives priority to homework and exam preparation. He also sets specific times for studying, exercising, and entertainment to avoid wasting time.
Second, about spending time with others, Nam thinks it's important to maintain good relationships. He joins sports clubs at school to spend time with friends. On weekends, he often goes to the cinema or plays badminton with his classmates. He also makes sure to have dinner with his family every day and shares his school experiences with them. When he faces difficulties with his studies, he doesn't hesitate to ask his teachers for help.
Third, to avoid stress and anxiety, Nam has several strategies. He takes short breaks every 45 minutes when studying to rest his mind. He listens to music or reads comic books when he feels stressed. Most importantly, he talks to his parents and friends about his problems instead of keeping them to himself.
Finally, Nam pays great attention to his physical health. He eats three balanced meals a day with plenty of vegetables and fruit. He goes to bed before 10 PM to get 8 hours of sleep. He plays football with his friends twice a week and cycles to school every day instead of taking the bus. He avoids eating too much fast food and drinks water instead of soft drinks.
I think Nam has very good habits for maintaining a well-balanced life!
