Global emissions（排放）of carbon dioxide from fossil fuel burning jumped by the largest amount on record in 2010. Emissions rose 5.9 percent in 2010, according to an analysis released on Sunday by the Global Carbon Project.
Scientists said the increase was almost certainly the largest absolute jump in any year since the Industrial Revolution. The increase solidified a trend of ever-rising emissions that will make it difficult, if not impossible, to stop severe climate change in coming decades.
The burning of coal represented more than half of the growth in emissions, the analysis found. In the United States, emissions dropped by a remarkable 7 percent in the year of 2009, but rose by over 4 percent in 2010, the new analysis shows.
“Each year, emissions go up, and there’s another year of negotiations, another year of indecision,” said Glen P. Peters, a researcher at the Center for International Climate and Environmental Research. “There’s no evidence that this path we’ve been following in the last 10 years is going to change.”
Scientists say the rapid growth of emissions is warming the Earth and putting human welfare at long-term risk. But their increasingly urgent pleas that society find a way to limit emissions have met sharp political resistance in many countries because doing so would involve higher energy costs.
The new figures show a continuation of a trend in which developing countries have surpassed (超过) the wealthy countries in their overall greenhouse emissions. In 2010, the burning of fossil fuels and the production of cement (水泥) sent more than nine billion tons of carbon into the atmosphere, the new analysis found, with 57 percent of that coming from developing countries.
On the surface, the figures of recent years suggest that wealthy countries have made headway in stabilizing their emissions. But Dr. Peters pointed out that, in a sense, the rich countries have simply exported some of them.
The fast rise in developing countries has been caused to a large extent by the growth of energy-intensive manufacturing industries that make goods that rich countries import. “All that has changed is the location in which the emissions are being produced,” Dr. Peters said.
Many countries, as part of their response to the economic crisis, invested billions in programs designed to make their energy systems greener. While it is possible, the new numbers suggest they have had little effect so far.

Going Zero Waste means more than just managing the rubbish we create．It means reducing it too．While it might seem like a difficult thing to do, it's well worth it．And what better time to start than Christmas?
We need to copy the way Nature wastes nothing．Many things are created by human society that we know will soon become useless and be thrown out．How many plastic bottles or even PCs end up in the rubbish bin? Instead，we should design products that can be more easily repaired，reused and recycled．
Kamikatsu, a Japanese village，has already gone Zero Waste．The 2，000 villagers compost their leftovers，and recycle everything else．There are 34 different boxes at the re-cycling centre! Residents grumble about the inconvenience，but they also see the benefits．
People who live Zero Waste lives are careful about what they do．They never take more than they need．Reusing plastic bags at supermarkets is a great way to reduce waste．And those who plan before they shop avoid having to throw food out later．Also，it’s best not to go food shopping when you’re hungry：You’ll be sure to buy too much!
Let’s think about how to enjoy a Zero Waste Christmas．By sending recyclable cards，we can help our friends and family reduce waste．And what better way to enjoy the spirit of Christmas than with a real tree that can be replanted in the spring?
Going Zero Waste requires us to think more about what happens before and after we act．It takes ambition，and it's not always easy．But just think how good it would be，both for ourselves and for the environment, if we never had to waste anything．
【小题1】When is this passage probably written?
| A．After a Christmas． | B．Before Zero Waste starts． |
| C．Before a Christmas． | D．When Zero Waste is very popular． |
| A．To stop using plastic bottles or even PCs． |
| B．To create more things that can be repaired quickly． |
| C．To avoid sending cards on Christmas． |
| D．To copy the way Nature wastes nothing． |
| A．taking no more than we need |
| B．reusing plastic bags |
| C．not going food shopping when we’re hungry |
| D．not making a plan before we shop |
| A．To enjoy a clean Christmas． |
| B．To complain about the pollution． |
| C．To educate people to behave well． |
| D．To call on people to attend Zero Waste． |
