Create wildlife­friendly areas in your backyard.When choosing your lawn and landscaping，choose native plants that can provide food or living places for native wildlife.This will also help cut down on pollution.Add bird or bat houses to your yard or garden to attract these species and offer places to them to live in. Avoid disrupting(扰乱) the natural ecosystem in your area.Non­native plants or animals can destroy habitats，particularly if there is no natural predator(捕食性动物) to keep the species in a certain amount.They can kill or disturb native plants that provide food and living places for wildlife. Practice a greener lifestyle.By saving water and fossil fuels，you will be helping to protect the wildlife around you.Take public transportation when you can，turn off electric devices when you're not using them，take shorter showers and keep your heat at or below 20 ℃ during the winter.Become knowledgeable about what can cause global warming，which disrupts migration patterns and habitats. Buy products that are wildlife­friendly.Avoid products that are made from threatened or endangered animals.Keep in mind that some endangered animals are killed by traps，or hunters who are after other wildlife within the same habitat. Talk to or write to policymakers about protecting wildlife.Write letters to a local newspaper.Discuss ways to help animals with friends and family members. Limit the family size.Population growth is one of the major factors in habitat destruction.By living in established city limits and limiting the family size to around two children per family，the earth's population will stabilize(稳定) and native habitats can be protected.

This machine breaks down the waste in less than 24 hours—reducing the volume by up to 90% —producing a material that can be put back on the farm. The machine works by using heat and enzymes to reduce the moisture content. It's hoped that 　it　 will help the environment. “Going to landfill is not sustainable. And it's doing a huge amount of damage to the environment.So, we are addressing this food waste on­site where it's produced，”said William Bedell, the machine provider. The farm and cafe are part of the same business. Much of the produce for the cafe comes from the farm. And the cafe is now sending back the leftovers. The process is quick, usually taking around 15 hours per load. Peter French，the cafe and farm owner told the reporter，“It's become noticeable over the years how much material goes to waste—food waste in the kitchen preparation and leftovers from table are full of nutrient that we really need on the farm to keep the soil healthy and productive for next year's crops.” “It just feels right to be returning that organic matter to the land that originally produced the food.The compost that comes out is a beautiful light，fluffy material.We will be spreading this back on the land through the spring for this year's crops.And it's hoped that the produce will end up back on plates in the cafe soon，”said Peter French. 5．What does the underlined word“it”in Paragraph 1 refer to? A．The new way.　 B．The machine. C．The food waste. D．Heat and enzymes. 6．Where does the food waste from the cafe go? A．The landfill. B．The farm. C．The cafe shop. D．The machine factory. 7．Which best describes the new way to deal with the food waste? A．Recycling. B．Productive. C．High­cost. D．Time­demanding. 8．Which best describes the new way to deal with the food waste? A．The cafe and farm owner cares more about making money. B．Food waste should be returned to the land directly. C．Kitchen preparation is the main source of food waste. D．The technology of dealing with food waste has a bright future. [语篇解读]　这是一篇说明文。文章主要介绍了英国沙尔登的克利伯咖啡馆将产生的食物垃圾送回农场，再次回收利用的事情。 5．A　[代词指代题。根据第一段中的“Food waste produced from the Clipper Cafe in Shaldon in the United Kingdom used to be sent away to landfill，but they have found a new way to deal with it.”以及画线词后文“will help the environment”可知，咖啡馆找到了处理食物垃圾的新方法，希望这种新方法能对环境有所帮助。由此推知，it指的是“新方法”。故选A。] 6．B　[细节理解题。根据第二段中的“The farm and cafe are part of the same business.Much of the produce for the cafe comes from the farm.And the cafe is now sending back the leftovers.”可知，咖啡馆的食物垃圾去了农场。故选B。] 7．A　[推理判断题。根据第二段中的“The farm and cafe are part of the same business.Much of the produce for the cafe comes from the farm.And the cafe is now sending back the leftovers.The process is quick，usually taking around 15 hours per load.”以及最后一段中的“It just feels right to be returning that organic matter to the land that originally produced the food.”可推知，处理食物垃圾的新方法是回收利用。故选A。] 8．D　[推理判断题。根据最后一段中的“‘...We will be spreading this back on the land through the spring for this year's crops.And it's hoped that the produce will end up back on plates in the cafe soon，’said Peter French.”可推知，处理食物垃圾的技术有一个光明的未来。故选D。] Ⅱ.阅读填句 Green tourism, a form of ecotourism, is low­impact tourism with an eye toward protecting the environment and culture of an area.As the number of tourists traveling the world has been increasing, green tourism is getting more and more popular. In some areas, green tourism is not only preferable but a necessity.It might seem wiser to some people to protect natural habitats and fragile (脆弱的)environments by banning visitors completely to these areas.　__1__　 Green, sustainable tourism is considered to have offered the best of both worlds, protecting the ecology of an area while keeping local schools and businesses booming. Green tourism doesn't necessarily mean a vacation spent with little or no comfort.　__2__　 Ecotourism exists in almost every style and taste.From gray water recycling systems to tents on tree house, there are numerous vacationing options.Simple efforts can go toward “greening up” a standard vacation, such as keeping to pointed pathways, 　__3__　 and visiting cultural areas instead of typical tourist attractions.
