[Gardener wanted.NASA requires a gardener to grow plants in a greenhouse.The successful applicant must be willing to travel long distances.The location is Mars.Transport will be provided.Please contact for further details and to arrange an interview.]
For the moment the position described above is an imaginary vacancy.It will probably be many more years before gardeners are needed on Mars.However, the actual growing of plants on Mars may be only a year away.Scientists are currently suggesting a mission that might put plants on Mars next year.
The idea is to use a small NASA spacecraft called a ’Mar Scout’ to send the plants in a miniature greenhouse.Landing on Mars it would scoop up some Martian soil.Enhance it with nutrients and then try to germinate and grow the seeds.The seeds would be bioengineered mustard plants, altered so that they would glow when they are struggling.Using bioengineering the mustard seed genes can be combined with jellyfish genes that make the plants glow with a soft green aura when they encounter problems.Healthy, thriving plants will not glow.When the scientists observe a plant is glowing, they can study it and learn what needs to be charged for plants to be able lo grow on Mars.
The aim of the experiment is to eventually be able to successfully grow plants in Martian greenhouses, and perhaps one day openly on Mars itself.What value does this have? After all, it would not be viable to farm food on Mars and then return it to Earth.
The meaning lies in being able to sustain life on Mars itself.It is far too expensive to transport all the supplies that would be needed by a Martian colony form Earth.So a crucial element for establishing a long-term human presence on Mars is a sustainable life support system.This is called ’ Bioregenerative’ , a renewable symbiotic relationship between plants, humans, and microbes.The humans produce the carbon dioxide and nutrients via their waste that the plants need, in turn they produce the oxygen and food that the humans need.The microbes make the process possible.Also, there is the social and symbolic value.When Earth life is actually growing on another planet that is likely to reignite interest in space travel: public interest and support for space travel is essential if governments are to be permitted to invest the huge sums of money required for such experimentation.
Questions 56—60 Complete the following schema with no more than three words for each blank according to the passage.

答案
interest and support
解析
根据题意定位至文章最后一段。 原文最后一句提到“When Earth life is actually growing on another planet that is likely to reignite interest in space travel: public interest and support for space travel is essential if governments are to be permitted to invest the huge sums of money required for such experimentation.” 由此可知,当地球上的生命正在另一个星球上生长,这可能会重新点燃人们对太空旅行的兴趣:如果要允许政府为这类实验投入巨额资金,公共利益和对太空旅行的支持是必不可少的。因此本空填interest and support。
