Translate the following passage from English into Chinese.

For more than two weeks this month, I commuted between two countries each day. And although it‟s not quite like being in Istanbul, where you can take a short boat ride to dinner in another continent, it‟s certainly been an experience.
It happened because, by the time I joined The Daily Telegraph last summer, there seemed to be no reasonable hotel rooms left in Copenhagen for the time of the climate summit. So I ended up in Malmo in southern Sweden, a 40-minute train ride, by bridge and tunnel, across the narrow straits between the two. This had its downsides. Waiting for the none-too-reliable trains in Arctic conditions was no fan; nor was negotiating in a blizzard with Malmo‟s notoriously crooked taxi drivers. But the benefit of the commute was that it enabled me to get to know two of the world‟s greenest cities. Copenhagen is so environmentally minded that it has been lighting its 60ft Christmas tree by pedal power: to keep it bright, passers-by have to jump on to one of 15 special bikes and generate the electricity themselves. And Malmo claims to be even greener.
In fact, the two have a none-too-friendly rivalry. Copenhagen aims to be the world‟s first carbon-neutral capital city by 2025; Malmo to be powered entirely by renewable energy by 2030. Copenhagen boasts 250 miles of bicycle paths, with 32 per cent of commuters using two wheels; Malmo, which has a smaller area, pips it with 255 miles and 40 per cent. Copenhagen was last week named as Europe‟s greenest major city; Malmo brandishes an award from the UN.Malmo will cut its carbon dioxide emissions by at least 40 per cent by 2020. In the process, it is growing, and attracting people, as never before.
And what is happening there, and in Copenhagen, is important to us, because the battle against climate change will be won or lost in towns and cities. They may only cover 5 per cent of the world‟s land surface, but they emit three quarters of its greenhouse gases. And as the World Wildlife Fund points out, they will invest $250 trillion in infrastructure over the next 30 years: it is important that this is green.
All this shows that we should stop being quite so unremittingly negative and gloomy. Even though countries seem unwilling to save us, cities might.
