Keep an eye on Citizens' Radio

One of the objectives of Citizens' Radio is to allow the public to hear more diverse music and political opinions.

But I think the broadcaster should be regulated by the government.

Even some legislative councillors attended a broadcast by Citizens' Radio, which is unlicensed. They should act more responsibly.

The Office of the Telecommunications Authority received a complaint from the Civil Aviation Department about the broadcaster's radio signals.

The department said the signals could disrupt Hong Kong's air traffic.

Citizens' Radio DJs also use foul language. This sets a bad example for children.

If the government opens up the airwaves, it could weaken the market share of the city's three main radio broadcasters.

Citizens' Radio should not abuse the freedom of speech enjoyed by Hongkongers.

The broadcaster should be regulated by the government.

Valuable tips on public speaking

It was an honour to have Philip Yeung as a guest speaker at our school recently.

Mr Yeung, who writes speeches for celebrities, gave us some very important tips about public speaking.

He reminded us that a good speech should contain three ingredients - levity, brevity and repetition.

Levity means humour. A boring speech could send our audience to sleep.

We can add spice to our speech by including some jokes related to our topic, Mr Yeung said.

By brevity, he meant that our speech should be short and sweet.

He said shorter sentences would allow our audience to 'digest' our words.

Finally, Mr Yeung said we should repeat our main points to ensure the audience knows where we stand on an issue.

I hope these tips are useful to you as they are to me.

Read more, and learn more

Many Hong Kong students worry about their academic results. They spend a lot of time reading school textbooks.

They don't have time to do any extra reading, like novels or newspapers. Many students think this is a waste of time. I don't agree.

The more we read, the more knowledge we gain.

Besides, it can improve our vocabulary and writing skills.

I hope Hong Kong students learn to enjoy reading.

Urgent need for tax on plastic bags

I support a tax on plastic bags because plastic bags cause tremendous damage to the environment.

They cause serious harm to wildlife, especially marine creatures. For example, turtles die when they swallow plastic bags which they think are jellyfish, their main source of food.

Moreover, there is no suitable way to treat used plastic bags.

If we burn them, they will release toxic gas. If we bury them, they won't dissolve completely and could destroy the soil and the surrounding environment.

They will haunt our planet forever unless we take immediate action. I don't see any reason why a compulsory levy on plastic bags should not be introduced.

It would surely reduce the amount of plastic bags being used in Hong Kong.

Damage to the environment would also be reduced.

People who oppose the tax are clearly selfish - they are just thinking about themselves, and don't care about the environment.
