Many cultures around the world have a grain that is not grown or even known outside its home area.
Now,an ancient grain from Ethiopia teff,is appearing in America.Teff has been an important part of the Ethiopian diet for thousands of years.Like oats,rice and wheat,it is a cereal(谷类的) grass.Teff is known for its small grain.It is used mainly to make flour(面粉).Teff has mild and earthy taste.Teff flour is the main thing for the well known flatbread found in Ethiopian restaurants.
Wayne Carlson learned about teff while doing public health work in Africa in the mid 1970s.In the late 70s,Wayne returned to the U.S,married and settled in southwest Idaho.Then he came up with an idea to grow teff in his home state.
Wayne and his wife Elisabeth are not farmers;nor do they want to be.So they convinced actual farmers in Idaho,Oregon and Nevada to grow teff for them.The Carlsons milled(碾磨) it themselves.
Until last year though,there was not a single Ethiopian restaurant in the entire state of Idaho to buy the milled flour.And that is how the business slowly grew for many years,serving the Ethiopian and Eritrean community in the U.S.
Wayne says teff production has increased over the past decade in the U.S..The grain has gone from 1,200 hectares in 2007 to more than 40,000 by 2014.He says most teff grown in the U.S.is fed to farm animals.In Idaho,however,more of the teff production is for human food.Teff contains lots of calcium(钙),iron and fiber.

Every year the Royal Botanic Gardens,Kew,and the New York Botanical Garden open their doors to thousands of visitors.They go there for the world famous orchid(兰花) shows.But these organizations are not just protecting living plants but also recording the culture connected with them.
Working with the Institute of Medicinal Plant Development,Beijing,Kew has developed a collection of plants—including orchids.The plants are collected in the forms they are used in traditional Chinese medicine.This is a storehouse of medical knowledge and a tool for cultural research.
Dr Barnabas Seyler,assistant researcher in the department of environment at Sichuan University,believes in the key role of botanical gardens.As an ethnobotanist(民族植物学家),Seyler is looking at the relationship between orchids and local culture of Liangshan.“They can help the culture continue to exist through providing protection,educating the general public,and supporting traditional knowledge,stories,and cultural traditions connected with these plants,” he says.
In China,orchids are more than just wild plants.“If you walk into any Chinese restaurant around the world,or into any tea house in China,you will likely find paintings,place settings,or other cultural things showing orchids,” he says.“Many people,especially in the west,do not fully understand the weight that the plant has held throughout history in traditional Han Chinese culture.”
The researchers have noticed that orchid species native to Sichuan are disappearing rapidly.Their beauty is killing them.Wild collected rare forms could be sold for thousands of dollars.In his study,Seyler asked locals of Yi and Han communities whether they could recognize different orchid species.They also asked them about how to find and grow orchids,and knowledge about orchids in arts and language.They found that when species were locally dying out,knowledge about them would be forgotten.
Culture doesn’t soon disappear because of the loss of one plant or group of plants.But what happens if species loss continues
4.What is Seyler’s opinion about botanical gardens
A.They can help keep orchid culture alive.
B.They will win more support from the public.
C.They should pay more attention to local cultures.
D.They can play a key role in environmental protection.
5.What does Seyler mainly discuss in Paragraph 4
A.The long history of orchids in China.
B.The many uses of orchids in the world.
C.The importance of orchids in Chinese culture.
D.The great influence of orchids on Western people.
6.What did Seyler’s study center on
A.How to prevent orchids from dying out.
B.What will happen to orchids in Sichuan.
C.How to increase knowledge about orchids.
D.What the loss of orchids will bring about.
