　　An environmental  group in Colombia is leading a project to save wild areas in the San Lucas Mountains with the help of coffee growers.

　　Since 2016，San Lucas areas have been  threatened by mining and coca（古柯） planting. Gold miners and coca growers make more money  than coffee farmers. Now the group WebConserva helps link coffee farmers with coffee processors from around the country in order that they can earn more. At the same time coffee farms can serve as borders around forests to protect the biodiversity within.

　　To date，the project includes 10 families who farm 400 hectares of coffee plants. WebConserva said it hopes，in time，200 families will be included.  At that level，20，000 hectares of untouched forest could be protected. The families promise not to cut down trees to expand their crops or to hunt wild animals. In return，they receive $300 for 125 kilograms of coffee.

　　Arcadio Barajas is among those taking part. His coffee farm sets up a barrier between cattle farms and forests where wild animals live，thus  reducing the possibility of conflict between cattle farmers and wild animals.“Cutting down the forest to plant coca and killing wildlife are against my faith，and now I feel that growing coffee lets me be a good guard of the land，”he said.

　　Arnobis Romero is a former coca grower and miner.“Many families depended on illegal activities to support their children years ago.  Now，we feel it a duty to look after this biodiversity and to leave it for future generations，”he said.

　　Activists want San Lucas to be protected as a national park，but the process has been slow. Carlos Valderrama，director of WebConserva，hopes the project can build production system that will last far into the future.“It protects forests，biodiversity and ecosystems at the same time as improving coffee growers’ quality of life，”he said.

1. What does the underlined word“they”in Paragraph 2 refer to?

A. Gold miners.  B. WebConserva members.

C. Coffee farmers.  D. Coca growers.

2. How does WebConserva save wild areas in San Lucas?

A. By setting up a barrier. B. By increasing cattle farms.

C. By developing gold mining. D. By encouraging coffee farming.

3. What does the author intend to show by mentioning Arcadio Barajas and Arnobis Romero?

A. There are families having a sense of duty.

B. The project will attract more and more families.

C. Families have enough money for their children.

D. Coffee planting will last for several generations.

4. What can be inferred from the text?

A. Families protecting wildlife will get very rich.

B. WebConserva benefits ecosystems and local people’s life.

C. Gold mining and coca farming have been replaced rapidly.

D. San Lucas will develop into a national park in the near future.

　　The Tibet Autonomous Region has placed nearly half its land area under the strictest ecological supervision（监督）. It was announced at an  annual meeting of the regional People’s Congress， which kicked off on Wednesday.

　　The ecological protection area，which covers more than 539，000 square kilometers，makes up 45 percent of the region’s area，and 22 ecological reserves have been built and are operational.

　　According to the government work report，the  rate of days with good air quality in Tibet’s cities has reached 99.4 percent，and all the region’s drinking water sources have met applicable standards.

Five cities and three  counties have been named as national-level  ecologically civilized model cities and counties， and more rural residents have benefited financially  by undertaking part-time ecological protection work.

　　More advanced monitoring facilities have been in place in the reserve，with more ecological protection inspectors employed to undertake protection work. The professional ecological inspectors are provided with basic tools such as motorcycles，telescopes and paging receivers，and they provide feedback regularly. Professional inspectors also receive one week of training every year from professors at Tibet University.

　　Kunsang Darje，a railway maintenance worker in Nagchu，said that apart from maintaining the railway and highway，he also collects trash along the section with his colleagues.“The place where I work is in a no-man’s land，and I think it’s very important to protect the animals there without affecting them with human activities，and we are  also bound to take responsibility there，”he said.
