Pass on headphones, protect your ears
If you are always listening to music on headphones, you should take better care of your ears.
According to my teacher, 35 decibels and less refers to faint or no sound, 55 decibels refers to moderate noise, 75 decibels refers to loud noise and 100 decibels and above refers to deafening noise.
Continuous exposure to noise above 50 decibels is harmful to your ears, and may lead to stress, irritation, nervousness and fatigue.
Try to give up the habit of listening to music loudly and using headphones. Apart from the fact it is dangerous when crossing roads, it is damaging your ears and perhaps your mental health too.
Remind your friends and family of the risks.

Ditch the brand names, go budget
Many teenagers like to buy brand-name products. These products are expensive because the company needs to earn more so it can advertise its products. The actual production cost of the goods they sell is very low.
Sometimes, the quality and design of rival products is excellent - and they cost less too. I suggest teenagers think about buying cheaper items. This will save money.
By all means, enjoy shopping but buy good things that come at a low price.

Give a helping hand to the elderly
Recently as I was downstairs in my building, I saw an elderly man walking slowly with a stick in front of me. He lives on the 30th floor.
When we got to the lift, its door was about to close and I rushed in, hoping to hold the door open for the man. I heard the old man cry out, 'Wait! Wait ...' But there was a woman with two children in the lift, and she pressed the 'close' button before I could act.
I felt terrible for the old man, and annoyed with the woman. It's not so hard to give the elderly a little help. And the woman is setting a very bad example for her children.

Some tips for learning Putonghua
Until recently Putonghua was very hard for me, but I realise now it was just a lack of practice. Thankfully, my teacher gave me some tips for picking up the language. The best one was the simplest. Watch and listen to more Putonghua on television and on the radio.
Practice makes perfect, and one hour of exposure to Putonghua every day on television and on the radio makes a huge difference.
Also, consider joining some extra-curricular activities, such as a Putonghua drama club or Putonghua speaking competition.
Many students feel that Putonghua is boring and useless, but, if we learn it, it is easier to find a good job - and we might make new friends too.
Save the animals
Recently, I read the article 'That's entertainment?' (South China Morning Post, March 15), and I was horrified to learn how terribly people treat animals.
We need to launch educational programmes to make people understand the plight of animals.
We also need severe punishment for people who mistreat animals.
