Billy always loved blueberries. They were his favorite fruit. Today he was going to make juice with his uncle. His uncle liked to make juice out of everything. He made carrot juice, apple juice, vegetable juice, and more juices. He had never made blueberry juice before though!
First, Billy and his uncle went to a blueberry farm. They were each given a basket. They picked for an hour and got several pounds. It was hard work picking the little berries from the trees. Now Billy understood why they were expensive in the store.
Next, they had to wash the fruit. Some of them still had leaves. Those had to be pulled off. Then the bad berries had to be thrown away. They washed the berries and made them air-dry.
After that, they pushed the blueberries through a strainer(过滤网). The strainer caught most of the seeds and skins, and only left a small glass of dark purple juice to them.
When they tasted the juice, it wasn't very sweet. Billy's uncle didn't want to add white sugar to the juice. It was better to use a naturally sweet juice, like apple juice, pear juice, or grape juice. They used grape juice as a sweetener (甜味剂), because grapes had a similar color to the blueberries.
Finally, they could drink it. It was a lot of work to make juice, but it sure was refreshing!
① wash blueberries. ②pick blueberries from trees. ③add grape juice to the blueberry juice. ④push the blueberries through a strainer.
Zhang Heng was a famous scientist in the history of China. His invention Hou Feng Seismometer was a great success and it helped us understand the world better.
(AD 78-139) | It was invented. Zhang Heng was born in Nanyang in the eastern Han Dynasty. At that time, there were many earthquakes every year. People thought they were from ghosts. Zhang Heng, however, didn't believe it. He tried to find ways to study earthquakes for many years and in 132 he invented the first seismometer in the world. |
It was used. But at first, people didn't believe it and all laughed at him. In February, 138, Zhang heng's seismometer told there was an earthquake in the west of Luoyang. After four days, three earthquakes really happened in Luoyang area. It was believed to be useful from then on. However, it was lost 1700 years ago. | |
It was reproduced(再生产). Scientists have been trying to reproduce one like that. In 2012, the latest reproduced seismometer was successfully listed in Shanghai museum. It was reported to have been a little helpful during the earthquakes in Tangshan, Yunnan and Sichuan. It is hoped to be improved better soon and be able to predict coming earthquakes one day. |
