The story began with his 6-year-old daughter.One day they were going on a hike when the girl noticed a     3     (break)plastic tub(浴盆)in a river.She said,“Daddy,that doesn’t go there.”That took Kirschner by surprise.He,like many adults,had become so used to the rubbish around them that he hadn’t given it a second look.    4     his daughter said reminded him of the serious problem our planet faces.

Jeff started to take       5    (act).He created Litterati,an app that makes it fun to pick up litter.The idea is       6    (fair) simple:Spot a piece of trash,take a photo,post the photo online and then put the litter into dustbins.

    7     (see)that Jeff was keeping a record of the positive impact he was having on the planet,people worldwide started participating.Up to now,over 2,500,000 photos posted by 3,500 people from over 40 countries     8     (find)their way to Litterati’s digital landfill.

Throughout the world, only 15% of the material that are used to make clothing is properly recycled, according to the Alle SacUrthur Club, an organization in Liverpool, UK, that boosts the circular economy. Most clothing waste—an     1    (estimate) 82 million tonnes from the fashion industry alone-produced every year ends up buried or burnt.

    2    (handle) all that waste, methods to recover and reuse the material are intended as an active response to the future risks by researchers and start-up companies. Much of their focus is on chemical recycling,     3     the material is broken down into its building blocks and applied to create new materials, including fibres that     4     (weave) into new clothes. The challenges lie in     5     (develop) the processes for such treatment. They have to be practical, but they also have to be at least as cost-effective as simply making new fibres.

    6     the natural cellulose fibres from cotton, some other materials include human-made cellulosic fibres. They are derived from wood-pulp cellulose and may be used to produce materials such as viscose (rayon) and a similar material called lyocell.

A change in the manufacturing process is being applied to the textile-waste problem by Essen, a start-up in Seattle, Washington.     7     the company has fundamentally devoted to the process is that it uses discarded textiles, instead of wood, as the source of its cellulose. It has also adjusted the process to produce a fibre that the firm’s co-founder and president Christo Stan says is superior to     8     other cellulosics and cotton, and that can be recycled more times.

Although there are abundant technical challenges, the main barrier     9     widespread textile recycling could be economic, says materials engineer Lijiang Jiang at the Massachusetts Institute of Technology in Atlanta. “Most of the materials are not that invaluable,” Jiang says. So cheap it is to produce polyester, cotton and other fabrics     10     there’s little profit margin unless the recycling processes themselves are very inexpensive.

The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change     1     coffee is grown from shade-grown production to full-sun production endangers the very     2     (exist) of certain animals and birds, and even disturbs the world’s ecological balance.

On a local level, the damage     3     (cause) by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a habitat     4     birds and other species that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many species are     5     (quick) dying out. On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens human life.

Medical research often makes use of the forests’ plant and animal life,     6     the destruction of such species prevents researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the local water and     7     (poison) the world’s groundwater in the future.

The loss of shade trees is gradually causing     8     slight change in the world’s climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming.

It is obvious that     9     (grow) much full-sun coffee affects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind     10     (be) surely worth more than an inexpensive cup of coffee.

The initiative is in line with the Chinese government's strategy of transforming the nation into a "Green Economy".       3     (accomplish) this objective,China has been taking aggressive action in expanding its green coverage.

For example,the "Great Green Wall" was initiated in the northern region to restrict the       4     (expand) of the Gobi Desert.
