January 16, 2014 –We know the saying“The early bird gets the worm”, but today you’re going to learn about the interesting saying “The early fish gets the bird.”
An African tigerfish(老虎鱼) was seen jumping out of the air and catching a flying bird. The African tigerfish has bright red fins and very sharp teeth. There have been rumors(传闻) this kind of fish preys on(捕食) birds since the 1940s, but no one was able to catch one.
"The whole action of jumping and catching happens so quickly that after we saw it, it took all of us a moment to really understand what we had just seen," said Nico Smit from Environmental Sciences and Management at North-West University.
Smit and his research team saw it at a lake in the Mapungubwe National Park in South Africa during summer. They found about 20 fish feeding on birds in the morning. Those birds may be out early to look for food, but we will never know for sure!

What do you think is the most common illness? Do you get ill sometimes? We are lucky to live now, because there are lots of medicines to make people better.
The most common illness in the world is the cold. It often begins with a sore throat. Then you sneeze and your nose runs. You usually have a headache too. Often you cough later. It’s not a very bad illness, but you can feel quite ill.
There isn’t a cure (治愈) for a cold, but you can take medicines to make you feel better. For instance, aspirin (阿斯匹林) can stop your headache. It is good to rest, and to drink a lot of water too. A doctor once said to me, “With the proper medicine, a cold will continue for seven days. With no medicine, it will continue for a whole week!”
Where does our medicine come from? A long time ago, people knew that some plants made them feel better. They ate the leaves, the roots, the fruit, or the seeds of plants. For instance, the juice of lemons makes a sore throat feel better.
In modern times, scientists have looked at these plants, and found out which chemicals (化学物质) are in them. Many of our medicines today are made from those chemicals.
There are some illnesses which we can’t cure yet. And nobody has found a cure for old age. But because of modern medicines, most people now live longer than their grandparents.
