America hopes to start building a base that can continue to exist all the time on the moon within 20 years.
By the mid-2020s, astronauts will be staying there for six months a time. So what do scientists think food
and water will be like for those first moon residents?
In the short term, food would have to be brought from Earth. The dream, however, is to grow things in
greenhouses on the moon. "You'd grow things in the liquid-there's no reason why that wouldn't work," says
Pillinger, a professor. This would mean floating plants in a nutrient-rich solution of water. "Soil is not a
necessary thing for plants; it's only to keep them standing upright," Pillinger adds.
It would take at least a decade of experiments after the base was built before such a plan would work,
however. The main problem is working out how to get nutrients from the lunar soil. "Getting all that to work
requires a minimum level of infrastructure (基础设施) present before you can start experimenting with
greenhouses," says Pillinger.
Finding strong plants to grow in space will also be hard, though scientists are already working on it:
scientist Amy Grunden of North Carolina State University has been working on genetically engineering food
crops that can be grown in harsh, off-planet environments.
Water is a somewhat easier prospect (前景). One of the reasons that America wants to put its base at
the moon's south pole is that it thinks that, in the permanently shaded craters, there are large pools of frozen
water. If that's true, it could easily be mined and used to drink and to create oxygen for the habitants.

I am an English teacher, with over 15 years' experience of teaching in London. I started
the DailyStep audio email lesson service because I noticed that when I started their English
course, my students' speaking and listening skills were much weaker than their reading and
writing skills. In my view, this is because education in school does not focus enough on
communication skills. DailyStep is designed to remedy this situation by offering more practice
in speaking, listening and vocabulary.
I am crazy about the English language and it is a real pleasure for me to see the
development of my students' language skills.
I majored in (以….为专业)law at university and then worked for three years as a
researcher and journalist for Sky television and BBC magazines. I decided to change to
English teaching because of my love of the English language and my wish to move into more
satisfying work.
Then I qualified (取得资格)as an English teacher in 1992. My first teaching job was at
a language school in Covent Garden, London, where I taught examination classes and
Business English . After two years, I moved to the Nippon Club where I taught General
English and Business English courses for 9 years. I also developed a unique course cal
led
British Society & Culture, covering all areas of British life, such as politics, law, e
ducation & music. At the same time, taught Business, Financial& Law English in the financial
centre of London. My students included staff (工作人员)from banks and law firms.
As well as running the DailyStep website, I also provide in-company English speech
training for companies in London. If you have an important speech coming up and would like
some information about how I can help you, please email me at jane@dailystep.com.
