Before science became professionalized in the 19th century,     1     naturalists were collecting information and helping us understand the natural world. A 2009 study found that nearly 50% of the UK     2    feed wild birds. The National Trust has more than 5 million members, and 60,000 active volunteers helping to protect the countryside as well as historic     3    . Now, with our environment arguably under greater threat than ever and species declining at a(n)    4    rate, volunteers are once again at the forefront of efforts to limit the damage.

Volunteers can be powerful drivers for big changes. On the Isle of Man, more than 8,000 people(nearly 10% of the population)are involved in regular weekend beach cleans. At one recent event, 123 volunteers turned up and removed 183 bags of litter in just a couple of hours. Thanks to     5    such as this, the island shares UNESCO biosphere reserve status with the Galapagos, Yellowstone in the US, Uluru in Australia, and hundreds of other sites.

Recreational divers are making a real difference underwater, too. They monitor the spread of     6    species, and record how native species respond. Divers also     7    levels of marine litter and other human impacts. Volunteers have also made a vital contribution to the conservation of basking sharks. The work of a citizen science Basking Shark Project in the 1980s and 1990s was     8    in getting these sharks on the protected species list in the UK, while satellite tagging     9    the first recorded trans-Atlantic crossing by a basking shark.

Actually, no one can know better, or care more about, our most special places than the volunteers who live in them and give up their free time to look after them. As a group of divers and     10    residents who live on the shores of the bay, they take their campaign on to national and international stages and continue to inspire people who might otherwise feel powerless when faced with threats to the places that matter to them.

Last Saturday, I went out to see a film after supper. On my     1     to the cinema, I met an Englishman. He looked puzzled (茫然的). So I walked up to him and said     2     to him. His     3     name was Kevin. I asked if I could help him. He told me he had     4     his way. So I     5     up the opportunity to see the film and took Kevin to his hotel.    6     going there, I told him the great changes that had taken place in my hometown in the     7     few years and Kevin told me     8     interesting about his country.

Though I didn’t see the film, I felt very     9    ，for I had not only helped Kevin get out of     10     but also practiced my spoken English. I also realized that if I had not worked hard at English, I would not have been able to help Kevin.
