1.People in developed countries usually get their drinking water from a faucet(水龍頭) or a bottle.But finding safe drinking water can be rather (54)difficultin developing countries.People in India,for example,often drink polluted water,which can lead to illness or even (55)death.But one Indian country,Sarvajal,has (56)inventeda great machine:the"water ATM".Sarvajal's water-filtering(水過濾) network has already (57)provided/produced/preparedclean water in more than 130places.Many of these places are small (58)villages.The water ATM is new and important part of Sarvajal's business. How do these water ATMs (59)work?First,local workers filter water using Sarvajal's equipment(設(shè)備).Then workers (60)sendthe clean water to the ATMs and sell prepaid (預(yù)付費(fèi)) cards to local people.Then they can (61)easilyget water from the ATMs with the cards. Thanks to Sarvajal's network and water ATMs,clean water is now (62)availbleto over 70.000people in India.It makes sense that in one of the local(63)languagesSarvajal means"water for all".
