Cartoon characters have the power
Cartoons are a popular form of entertainment for young children.
Children like to act like the characters in their favourite shows, so the cartoons play an important role in forming children's personalities.
But when viewers become teens, they often lose interest in cartoons. A show has to be really well made, with brilliant storylines, to attract teenage viewers.
A recent educational cartoon from the mainland, Happy Sheep and Grey Wolf, is an example of how cartoons can put people off. While it teaches important lessons, the images are too childish and the storylines are badly planned.
If these things were changed, the show would be more attractive.
With a little thought and care, cartoons can be used to teach important lessons to viewers of all ages.

A remarkable but tragic life
Michael Jackson took his first step towards fame when he was only a child. His impressive talents made him stand out. He was destined for huge success.
Unfortunately, with success came a lost childhood and loneliness. He couldn't live a normal life because he was always in the public eye.
As an adult, he tried to recreate his childhood, building a home called Neverland and spending time with children, which landed him in legal trouble.
Unfortunately, Jackson's often bizarre behaviour overshadowed his genius. People forgot how much effort he put into raising money for charity. They forgot how many Grammy awards he had won and how many No1 singles he had produced.
People forgot why he was called the King of Pop.
While his death on June 25 was a great loss for the world, I feel at least he's no longer being criticised.

Online learning offers benefits
Online learning is becoming increasingly popular. The internet allows us instant access to all sorts of knowledge at any time.
Learning is no longer confined to traditional textbooks and classrooms. What's more, online learning platforms provide interactive bonuses like animation and sound, which make learning more interesting.
Although online learning is beneficial and an effective way of education, excessive use of the computer can lead to internet addiction.
We should learn to use online learning resources wisely, and not be distracted by other sites. Time is precious, so make the most of what the internet has to offer, and then switch the computer off.

Drug testing unlikely to help addicts
There has been a lot of discussion about the drug-testing scheme being introduced this school year.
Some people have criticised the move, saying the scheme has been introduced in too much of a hurry.
A government spokesman has even said by law, students have the right to refuse to be tested.
If I were selected, I would refuse. I don't take drugs, but one in five sample tests has been found to give the wrong result. Students could be wrongly accused of taking drugs. Those who do take drugs could get away with it.
A better scheme would be to focus on the reasons young people take drugs. While some take them because they mistakenly think it's 'cool', most start because they are stressed or worried.
The government could help drug addicts more if they focused on counselling and support.
