Four New Cool Inventions
Mip
Mip, a playful robot, was developed by a Canadian toy maker named Wowwee. It stands 19 cm tall. You can control it simply with your gestures(手势) or a smart phone. Mip can run, balance and dance on two wheels. It can also bring you a bottle of water.
Android Wear
Google is developing a smart watch called Android Wear. The watch uses a touchscreen and voice control. Simply say “OK, Google” to ask what ever you want to know. For example, say “OK, Goodgle. Where’s the nearest toy store?” Your answer will tell you the answer on Google Maps.
Le Pen
Do you like listening to music while doing homework? If you do, you will like Le Pen. With a music player planted inside, Le Pen plays music while you write on paper. The music stops when you stop writing. So if you want to enjoy more of your favourite songs, keep on writing.

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
"We’ve learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It’s hard to get a clear result.
Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
"It’s our first scientific journey, Huang said, "But it makes me want to try harder." Whom did the three kids want to challenge?
| A．Their chemistry teacher. | B．Their headmaster. |
| C．Robert Boyle | D．Thomas Edison |
From the text, a red cabbage is a kind of ____.
| A．plant | B．animal | C．paper | D．liquid |
What is widely used as the acid-base indicator now?
