prey(猎物) has seen them and will give up，since theyve lost the element of surprise.this psychological trickery has been called “icow”，which is actually not as strange as it sounds.the eyelike patterns on butterfly wings are known to prevent preying birds and woodcutters in indian forests wear masks on the backs of their heads when working to discourage hungry tigers.the inspiration for the icow strategy came while jordan was based in a village in botswana，when two lionesses were killed by local farmers to revenge their cattles death.the african lion is a vulnerable species，with numbers dropping from over 100,000 in the 1990s to about 30,000 today.much of that decline is due to these kinds of revengeful killings because farmers have no effective strategies for protecting their herds.“lions are hunters that like to attack by surprise.they move slowly，quietly，and carefully to their prey，get close，and jump on them unseen，”he said.when jordan was watching a lion follow an antelope one day，he noticed the lion gave up the hunt once the antelope spotted it.so he joined one of the local farmers on a 10week trial study，painting eyes on onethird of a herd of 62 cattle.when the cattle returned each night，they took a head count to see how many had survived.only three cows were killed by lions during this periodall without the painted eyes on their behinds.and all the painted cows survived.however，jordan warned that so far this is just a promising idea.he is now back in botswana for a more ambitious study，equipped with gps devices to better monitor the movement of predators(捕食者) and prey.28the icow strategy is designed to .akill the lions bscare off predatorscidentify cattle dhave fun29when hunting，lions like to .agive up halfwaybhesitate to take actioncchase their prey steadilydlaunch surprising attacks30what does the underlined word “vulnerable” mean in the third paragraph?abadly behaved. blikely to attack.ceasily cheated. deasily damaged.31what can be inferred from the passage?aneil jordan got the inspiration from the patterns on butterfly wings.bin the 10week trial study，more cattle were killed.cthe icow strategy is likely to bring great benefit.dthe farmers will continue to take their revenge on the lions.d(2018河南豫南豫北名校精英联赛)pollutions great effects on the environment have become more obvious in recent years，leading to a movement to promote energy efficiency(效率)，less reliance on fossil(化石) fuels，and a reduction in air and water pollution.most scientists agree that such changes are necessary to protect our environment from further harm.the construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution.in the united states，building and development account for 39% of the countrys total energy use,12% of total water consumption,68% of total electricity consumption and 38% of carbon dioxide emissions(二氧化碳排放)，according to the environment protection agency.green buildings use less energy，water，create less waste，and are healthier to live，work，and go to school in than standard buildings.builders of green buildings use techniques that use resources more efficiently during the entire building cycleconstruction，restoration，operation，maintenance(维护) and demolition(拆毁)than those who construct more regular buildings.the environmental benefits of building green include the protection of ecosystems(生态系统) and biodiversity，improved air and water quality，less waste flowing into streams，and the protection of natural resources.green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality，improving the health of people who live in such buildings.the process of building green includes technical and artistic planning with nature protection in mind.building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw.in addition，recycled resources found locally are used for green buildings，reducing the cost and air pollution associated with transporting materials over long distances.careful site selection is important to minimize(最小化) human impact on the surrounding environment.for example，placing a structure in an area that allows it to take advantage of cool breezes(微风)and sunlight can reduce energy use and expenses.more energy and expense are needed for larger buildings as well，so it is important to build small.green roofs are another feature of green houses that reduce energy use and cost.these roofs are partly or completely covered with plants，which helps to keep heating and cooling costs，prevent water running off and deal with pollutants.other features of green buildings often include energy and water conservation，recycling，and waste reduction.in addition，renewable energy sources such as solar power，hydropower(水能) and wind power are used for heat and electricity，which greatly reduces costs and decreases the impact on the environment.32what is the text mainly about?athe necessity of promoting energy efficiency.bthe process of building green buildings.cthe benefits and features of green buildings.dgreen buildings effects on the environment.33according to the text，green buildings refer to the buildings that .aproduce no wastebonly use clean energycare made of recycled materialsduse energy and resources more efficiently34which of the following statements is true about green buildings?athey rely on fossil fuels and solar power for heat and electricity.bsmall buildings are less efficient in energy use than larger ones.cthe ecosystem has to be considered when building a green building.dthey are difficult to maintain and thus need more operating costs.35why are green roofs used?athey fit the surrounding environment well.bthey are cheaper than other kinds of roofs.cthey can keep natural water for use in everyday life.dthey can help to control the temperature in the building well.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。(2018河北石家庄一中质量检测)i like travelling very much. 36 they are wonderful adventures filled with new sights and
