清洁
1.Well, lately when I've been arriving at work in the morning. The office isn't as clean as it used to be. I think we might need to find another cleaning company.
嗯.最近我早上上班到公司时发现办公室没以前干净了.我认为我们也许有必要再找另一家清洁公司.
2.We need to solve the problem of air pollution before we destroy the atmosphere. There`s lots of clean, modern technology, but companies in developed countries say it`s expensive. Developing countries put more emphasis on economic development than on envir
我们需要在大气层被破坏以前解决空气污染问题,这里有很多清洁的现代科技,但是发达国家的大公司们都说成本太高.发展中国家游吧精力集中在发展经济上而不注重环境保护.
