Here is a timetable of courses in Children’s Palace.

Why did Chinese people have more than one name in ancient times?

In ancient China, people’s names had three parts, their family name, given name and courtesy name. Take famous poet Li Bai for example. His family name, which came from his father’s name, was Li. His given name was Bai, and his courtesy name was Taibai.

People used their given names when they were among family members. But in social life, they called each other by their courtesy names to show respect. This was mostly done among people of similar age. If you were talking about yourself, or if your elders were talking about you, the given name would be used instead of the courtesy name.

Men would get their courtesy names when they turned 20. It was a symbol of adulthood (成年礼). Women would get their courtesy names after getting married.

One’s courtesy name often had something to do with one’s given name. For example, the name of Mencius was Meng Ke. His courtesy name was Ziyu. Both Ke and Ziyu mean “carriage (马车)”. Zhuge Liang’s given name was Liang, which means “bright”. His courtesy name was Kongming, which means “very bright”.

What is a tsunami(海啸)? Tsunamis are often caused by earthquakes or volcanoes(火山). The average speed(平均速度)of the waves(波浪)is 300 mph and the waves can last from five minutes to an hour.

What to do in a tsunami?

Firstly, when a strong earthquake is felt, leave the water at once, get to the shore(海岸)and go as far away as you can from the beach fast. If it allows, go to a higher ground.

Secondly, turn on the TV for news and weather report. They will tell you more about the tsunami.

Thirdly, get all members of your family together and let everyone know the tsunami is coming. Choose a place to stay together. Make sure the place is safe and as far away from the shore as possible. Bring emergency supplies(应急用品)when you have to leave your house.

At last, if you find a huge wave is coming, climb onto the roof of your house or on the highest point of the nearest building. Hold on to anything that’s strong enough. Climb a tree if you have to.

For a tsunami, the only way to survive(幸免于)it is to be prepared.

You may know about “junk food” like French fries. But do you know about “junk sleep”? Recently, a British survey(调查)shows that there are many electronic products in teenagers’ bedrooms. They are influencing teenagers’ sleep badly.

The survey was done among 1,000 British kids from 12 to 16. It found that 50% of them got just 4 to 7 hours’ sleep every day. But doctors say they need 8 to 9 hours.

Almost 25% of the kids said they often fell asleep while they were watching TV, listening to music or using other electronic products.

“This is very worrying,” said Dr. Chris, a British professor(教授). “We call it ‘junk sleep’. It means you don’t get enough sleep and the quality(质量)of the sleep is low, too. If you don’t get a good rest, you won’t do well in school the next day.”

The survey found that quite a few of the kids felt tired each day because of the junk sleep, especially girls between 13 and 16 feeling the worst. Nearly all the teenagers have a phone, MP5 or TV in their bedrooms. And lots of them even have all the three.

Dr. Chris suggested that parents should help their children keep away from electronic products, and teenagers should spend less time on the electronic products.
