As we all know, there are many kinds of pollution all over the world, air pollution, water pollution, noise pollution and so on. Although we can't save the world in a short time, we can take   some measures to protect     1    . For example, we can prevent people throwing litter; we can sort the rubbish in the community; we can drive less and produce less carbon dioxide.

    2     (actual), there is a new recycling program at our school, which aims to help us create     3    better environment. The recycling we've planned is simply a three-part program: sorting, collecting and delivering. The first part — sorting is also the     4     (hard) one. Most people don't like taking the time to do the     5     (separate) of the rubbish and this is usually why most recycling     6     (program) fail. However, we have reasons     7     (believe) that our words will work. From now on, instead of seeing the usual black rubbish cans all over the school, you     8     (see) three different colors of rubbish cans. Pink cans are for paper, blue cans for bottles, and white ones for all other waste. After the rubbish     9     (sort), it needs to be collected and then taken     10     different rubbish recycling centers.

Do you know human-wildlife conflict?

Human-wildlife conflict, referring to direct interactions between humans and wildlife with negative outcomes, costs the     1    (globe) economy billions of dollars annually. Worse still, it     2     (threat) human lives and causes many species to die out. These conflicts     3    (large) result from humans and wildlife seeking limited resources in the same landscapes and often have many     4     (expect) consequences. As a matter of fact, both extreme climate events and climate change have the potential to influence the interactions between humans and wildlife. Serious climate events can bring about rapid changes in resource availability,     5    may drive strong responses in animals and people. The     6    (compete) between the two grows tougher as a consequence. Droughts     7     particular have caused some of the most visible conflicts. Despite the gravity of these conflicts, climate change is making human-wildlife conflict even     8    (serious). With people and wildlife sharing crowded spaces and limited resources, human-wildlife conflict is rising in frequency. Many people,     9    , still haven’t really realized how complex and severe the problem is. Therefore,     10    (protect) wildlife and humans alike, it is vital that a wide range of research and institutions should consider the role of a changing climate in shaping the complex dynamics of conflict.

For those consuming Asian food, using chopsticks is almost second nature. About 20 to 33 percent of people in the world use chopsticks     1    a daily basis. Not all of those are disposable (一次性的),     2    no doubt many are.

Felix Bock, a student at the University of British Columbia, was eager to find a way     3     (recycle) wood from construction projects, and he had a particular interest in bamboo. One day he noticed a drawer in his friend’s house filled with disposable bamboo chopsticks, and an idea hit     4    .

He decided to give     5    second life to disposable chopsticks by making them into home     6    (decoration) or other accessories (配件). He told the idea to restaurant owners,     7    (convince) them to install recycling bins in their restaurants. He cleaned the chopsticks, pressed them into square pieces and coated them with glue. The square pieces were then     8     (creative) arranged into household and office products. Bock’s company, called Chop Value, has repurposed chopsticks into desktops, cutting boards and even table games.

Since 2016 when the company     9    (found), Chop Value has rescued billions of chopsticks from landfills. Instead of an economy of the typical take-make-dispose model, Chop Value seeks to create one     10    transforms waste into a usable resource.
