Sichuan Giant Panda Sanctuaries (栖息地) has great 【小题1】 (important) for the conservation of the giant panda, 【小题2】 (recognize) as a “National Treasure” in China and an icon of 【小题3】(globe) conservation efforts. It is the largest and most important remaining area of panda habitat in China and the world, consisting of seven nature reserves and nine scenic 【小题4】 (park).

In addition 【小题5】 the giant panda, the property features 【小题6】 great number of local and threatened species of plants and animals, including other iconic mammal species, such as the red panda and snow leopard. The property is an important center for some birds, 300 of 【小题7】 breed (繁殖) locally. Besides, the property is 【小题8】 (particular) important for plants, 【小题9】 (become) one of the botanically richest sites of any temperate (温带的) region in the world. The property is a major source and gene pool for hundreds of traditional medicinal plants, many now under threat. Because of its biodiversity and conservation of giant pandas, these reserves 【小题10】 (list) as UNESCO World Heritage Sites in 2006.

Each year, billions of pounds of trash and other【小题1】（pollute）enter the ocean. Where do they go? Some sinks, some is eaten by sea animals【小题2】mistake it for food and some washes up on our beaches.

"There's almost nothing【小题3】（bad）than oceanfront sands littered with trash. It could be paradise," said Ma Jiayu, who joined the International Coastal Cleanup event, which was held by the Blue Ocean Conservation Association（BOCA）,【小题4】nonprofit organization in Shenzhen.

On the third weekend of last September, hundreds of volunteers【小题5】（arm）with bags, gloves, litter pickers got to work cleaning beaches. The volunteers—【小题6】（include）teenagers, teachers, workers and statesmen—【小题7】 （separate）into 26 cleaning spots along the 260.5 kilometer coastline.

Founded by a few divers, the BOCA has long gone to the bottom of the ocean to clean.【小题8】heavy scuba tanks （潜水空气瓶）,masks and dive fins, divers face the dangers of low visibility or getting stuck. But they are happy【小题9】（save）clownfish and protect the coral reefs.

"Change comes from each of us, through our actions and【小题10】（behave）. If you do it, others might do it as well through the power of example. And they will teach others to do it too, and slowly, our plant might start being a cleaner place," said Ma Haipeng, the chairman of the BOCA.

Now, Mount Everest is actually an interesting comparison of a new approach 【小题1】how we deal with garbage produced in the course of space exploration, as it’s often given the dubious hono r(耻辱) of being the world’s highest garbage dump. Decades after the first conquest of the world’s highest peak, tons of rubbish left behind by climbers 【小题2】 (start) to raise concern, and you may have read in the news that there’s expectation 【小题3】Nepal will crack down on mountaineers with stricter enforcement of penalties and legal obligations. The goal, of course, is to persuade climbers to clean up after themselves, so maybe local not-for-profits will pay climbers who bring down extra waste, or expeditions might organize voluntary cleanup trips. And yet still many climbers feel that independent groups 【小题4】police themselves. There’s no simple or easy answer, and even well-intentioned efforts at conservation often run into problems. But that doesn’t mean we shouldn’t do 【小题5】is in our power to protect the environments that we depend on, and like Everest, the remote location and inadequate infrastructure (基础设施)of the orbital environment make waste disposal a challenging problem. But we simply cannot reach new heights and create an even higher garbage dump, 【小题6】out of this world.

The reality of space is that 【小题7】a component on a satellite breaks down, there really are limited opportunities for repairs, and only at great cost. But what if we were smarter about 【小题8】we designed satellites? What if all satellites, regardless of what country they were built in, had to be standardized in some way for recycling, servicing or active deorbiting (脱离轨道)? What if there actually were international laws that enforced end-of-life disposal of satellites instead of moving them out of the way as a temporary solution? Or maybe satellite manufacturers need 【小题9】(charge) a deposit to even launch a satellite into orbit, and that deposit would not be returned 【小题10】the satellite was disposed of properly. Or maybe a satellite needs to have technology on board to help accelerate deorbit.
