No one knows how man learned to make words. Perhaps he began by making sounds like those made by animals. Perhaps he grunted like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him—water splashing, bees humming, a stone falling to the ground. Somehow he learned to make words. As the centuries went by, he made more and more new words. This is what we mean by language.

Rice is one of the most commonly eaten basic foods around the world.Buying it and cooking it is a daily matter.Yet for many，its presence has been a matter of life and death.It is a main food because it is easy to grow，besides low cost and convenience.A poor community in the developing world may find it difficult to bring in foreign fruits or raise cattle for meat，but it can almost certainly use the land it has in order to grow plenty of rice.
This was the great achievement of Yuan Longping，who passed away on May 22 this year.A great Chinese scientist，Yuan successfully developed what is known as "hybrid rice" which can produce up a 30% higher output.Yuan Longping was born in the year 1930，a time when China was very different.It was a nation，without modern industry，depending on the rice which they grew.The first few decades （十年） of his life were met with major social events，and a rapidly growing population that made food supply not last all the time.This experience left its mark on Yuan Longping，which made him focus on （关注） farming science and work on his research of hybrid rice.
His achievement would see the rice supply in China increasing from 56.9 million tons in 1950 to 194.7 million tons by 2017.By 1991，20% of the world's rice output came from hybrid rice，even if only being planted in 10% of fields.
Always remember，human development begins first with the most basic and sample things，such as developing rice.We should be thankful for scientific thinkers like Yuan.

What do you do with your rubbish？Throw it out？You don't know what you're missing!Look closely at the two figures on your left.They were made from things most people throw away.The figures were made from used bottle caps.Those two bottle﹣cap figures were exhibited （展示） in a museum.
Folk art is art made by common people who have not been trained as artists.Their work is often based on traditions in their culture.Fine art，on the other hand，is usually made by people who have had training in art.Works of fine art are valued for their artistic beauty.They are supposed to be looked at but not used.Works of folk art，however，are often made for everyday use.
There were more than 800 pieces of folk art from nearly 50 countries in the exhibition.All of the pieces were made from used metal，wood，cloth，and plastic.The artists come from many different cultures.Still，they all share one thing.They take objects that are normally thrown away and change them into objects that are beautiful，useful，and fun.The artists may not think of what they do as recycling，but that's exactly what it is.Fine artists might work with expensive materials.They might use expensive tools to shape these materials into works of art.On the other hand，in poor countries rubbish might be the only material folk artists and toy makers can afford.The exhibition shows that a rich imagination is very important when there are only poor materials.Recycled art began long before people began to think about recycling.Some of the objects in the exhibition date from the 1930s.
Even if you don't create art out of rubbish，it's good to save our natural resources.Remember the three rules：reduce，reuse，recycle.If you reduce waste，true things instead of throwing them out，and recycle materials such as paper，plastic，and glass，you will protect the environment.
