China's second female astronaut, Wang Yaping, has given the country's first-ever video lecture from space. The whole lecture lasted about 40 minutes.

Speaking to students through live video, from the Tiangong-I space laboratory, Ms. Wang used spinning tops (旋轉(zhuǎn)的陀螺), a ball and some water to explain physics in zero-gravity(失重), with the help of a fellow astronaut.

Ms. Wang used different experiments to demonstrate the concepts of weight and mass (重量和質(zhì)量的概念) in space. Towards the end of the class, Ms. Wang made a film(薄膜) of water using a metal ring. She then turned the film of water into a water ball by pouring more water onto it.

Around 330 primary and secondary school students watched the lecture from a special classroom in Beijing, where they could also ask Ms. Wang questions through live video. From time to time, the students greeted her lecture with warm applause(掌聲).

When answering a student's question, Ms. Wang described what she could see in space. "The stars we see are much brighter, but they do not twinkle(閃爍)," she said, "The sky we see isn't blue, but black. And every day, we can see the sun rise 16 times because we circle the Earth every 90 minutes."

About 60 million students and teachers around China also watched the lecture live on TV.

Hello, this is your gardening adviser. Now, just as our garden are at their most colorful, and most productive time, what do we do? We'll go off on holiday. What I suggest you do is this: invite a friend or neighbor to help you. You can ask him to water the plants in the greenhouse until you return, but first make sure that he knows how to do it. What he should not do is throw water over the leaves of the plants themselves, because if he does that, it will invite diseases. Also for the same reason, ask him if he can possibly water in the morning, rather than in the evening.

If you haven't got a greenhouse, there is one safe and easy way to keep the plants well when you are away, and this is how you do it. Place six-inch-deep newspapers in the bottom of the bath. Yes, the bath! Turn the tap on and keep the water running until the papers are all wet. Now put the flower pots (花盆) to stand on the wet paper, go off holiday, and they should be alive and well when you return in two weeks' time.

Thank you for calling. Goodbye and good gardening!
