The 24 Solar terms came into being during the Qin 211-206BC and Han 206BC-AD220 dynasties. 2 So, weather changes were important. But of course, they had no satellite, Internet or weather broadcast to help them.

3 They studied the sun’s movement with a sundial(日冕仪).They also paid attention to other natural changes such as temperature, water and crops growth. In the end, they worked out the 24 Solar terms to mark the changes.

4 For example, the solar terms jingzhe(惊蛰)is when insects wake up from a long sleep in the cold winter. Farmers take it as a sign of warm weather and get busy working.

【题目】 Imagine having an ear made out of an apple. It seems like a crazy idea. But it could happen in the near future.

Canadian biophysicist Andrew Pelling used an apple to grow a human ear. He thinks fruit and vegetables can be used to cheaply repair human body parts in the future.

Scientists have been trying to grow organs in labs to replace our old ones. But it‘s a hard job. In the past, scientists have used man-made materials, animal parts and even dead people as scaffolds(支架). But that has proved to be difficult and expensive.

Pelling and his team, however, found the apple to be a cheap and easy-to-use scaffolds.They first cut an apple into the shape of an ear. Then they used a special way to take out the apple‘s cells(细胞)and make it a scaffold. The team then added human cells to the apple, and watched it grow. “You can implant(移植)these scaffold into the body, and the body will send in cells and a blood supply and actually keep these things alive, ” Pelling said during a Ted Talk speech.

The team put the apple scaffold inside a living mouse and the mouse’s cells slowly take over the pieces of the apple.

Now Pelling is thinking of the other fruit, plants or vegetables to use.
