Analysis of millions of infrared (红外线) photos and tens of     1    (thousand)of videos shows that the Sanjiangyuan area in the heart of the Qinghai-Tibet Plateau has one of the most complete food chains in the world. The analysis    2    (carry) out by the Shan Shui Conservation Centre more than a decade ago. A professor of conservation biology at Peking University,    3    founded the center in 2007 and has    4    (continuous) worked on the preservation of Sanjiangyuan for 17 years, said, “Conservation of nature is not about shouting slogans (口号) related to keeping rare animals alive It is not something you can learn from textbooks. Reality always    5    (tell) us what the problem is. Apart from protecting animals and the environment, we need to pay attention to the people who share the natural environment     6    wildlife. Wildlife conservation is all down to humans”.

Since her 20s, the professor has been devoted to protecting     7    researching endangered wildlife such as pandas and snow leopards,     8    (promote) the establishment of protected areas and related laws and policies. The conservation center has worked with the park’s management committee     9    (develop) supervisory(监管) systems, and provided product design     10    (solution) for nature experience programs.

The first “forest library” in Shanghai recently opened to the public, giving readers the chance     1     (relax) and read in a natural environment.

Known as Read & Joy Forest, the forest library that was     2     (joint) launched by Pudong New Area and Shanghai Library     3     (locate) in an urban green space area near Shanghai Library East. Covering an area of 20,546 square meters, it allows visitors to take a pleasant walk in the quiet and green forest,     4     includes many different kinds of trees.

The design of the forest library ensures minimal (极少的) disturbance to the forest, with existing green spaces     5     (connect) by wooden walkways. The library is in the open air and equipped with facilities such as benches and     6     information desk.

    7     (have) a library in the woods is an extension of reading indoors, according to Xu Qiang, one leader of Shanghai Library. “It offers different reading experiences to readers,” Xu added.

Most of the visitors to the forest library were young people and parents with their children, who either immersed (沉浸在) themselves in reading     8     took wanders leisurely in the forest. “The fresh air and the scents of the trees here are really     9     (impress). I’ve spent the whole morning indoors, and wanted to get some fresh air. The library makes it possible to enjoy reading in natural surroundings. I must say I have a     10     (prefer) for it,” said one reader sitting on a bench.

Plastic pollution at sea is reaching     1     (worry) levels. According to a review of hundreds of academic studies, it will continue to grow even if significant action is taken now     2     (stop) such waste from reaching the world’s oceans. The review by Germany’s Alfred Wegener Institute examined almost 2, 600 research     3     (paper) on the topic to provide an overview ahead of a United Nations meeting later this month.

As plastic breaks down into smaller pieces, it also enters the marine food chain,    4     (take) in by sea creatures from whales to turtles. What’s worse, some regions already contain dangerous levels of plastic, and others risk becoming     5     (increasing) polluted in the future. Getting that plastic out of the water again is nearly impossible,    6     policymakers should focus on preventing any more of it entering the oceans in     7     first place. Matthew MacLeod, a professor of environmental science at Stockholm University,    8     (involve) in a separate study not long ago,    9     also concluded effective measures are required immediately because of the possible global impacts.

While consumers can help reduce plastic pollution by changing their behavior, governments have to step up and accept     10     (responsible) for solving the problem. It’s a global problem and it needs global solutions.
