For around 40,000 years before European settlement commenced in the late 18th century, the Australian mainland and Tasmania【 B3】 _around 250 individual nations of local Australians. After【 B4】 _visits by f
19、ishermen from the north, and European discovery by Dutch explorers in 1606, the eastern half of Australia was【 B5】_by the British in 1770 and initially settled in the colony of New South Wales, founded on 26 January, 1788. The population【 B6】 _in the following years and the continent was explored th
20、oroughly. During the 19th century, another five largely self-governing Crown Colonies were【 B7】 _. Since the six colonies became a federation and the Commonwealth of Australia was formed, Australia has【 B8】 _a stable liberal democratic political system and remains a Commonwealth realm. The populatio
21、n is just over 21.3 million, with about 60%【 B9】 _and around the mainland state capitals of Sydney, Melbourne, etc. Technologically advanced and industrialized, Australia is a prosperous multicultural country and has good results in many international【 B10】 _of national performance, such as health c

23、per that would transform how food is stored and kept fresh. Ten years later, her product is being used in 35 countries, has been called “the【 C1】 _paper“ and was recently launched in Whole Foods. Fresh Paper is infused with organic spices that inhibit【 C2】 _and fungal growth; when stored with produc
24、e, it can keep food fresh two to four times longer than normal like refrigeration without electricity. The spice mixture comes from an old family recipe passed along by Shuklas grandmother, who once gave it to her after she【 C3】 _drank tap water on a visit to India. “Drink this and you wont get sick
25、,“ she was told. On Friday, Shukla was joined onstage at the Women in the World Summit in New York by Rula Jebreal, a【 C4】 _and foreign-policy expert at MSNBC(微软全国有线广播电视公司 ). Jebreal lamented the fact that while the worlds farmers actually produce enough food to feed the worlds hungry, 13 billion to
26、ns of food are lost annually to spoilage. Whats more, some 1. 6 billion people currently living without【 C5】_to refrigeration struggle to keep their diets healthy. Shuklas company, Fenugreen, which she started in 2010,【 C6】 _these people, along with food banks and small-scale farmers. “For so many p
27、eople, this was about so much more than a piece of paper,“ she said. “It was about empowerment. “ Jebreal praised a low-tech solution in an era when many【 C7】 _are relying on high-tech innovation. “What if I had【 C8】 _it as too simple?“ Shukla asked. “Simple ideas are the ones that have the power to
28、 change things.and they have the power to【 C9】 _. “ For Fresh Paper, simplicity meant accessibility, which was key to【 C10】 _the product reached anyone who could benefit from it.

30、6 10 Ways Obama Could Fight Climate Change AOne of the biggest surprises of President Barack Obamas inaugural address on Monday was how much he focused on fighting climate change, spending more time on that issue than any other. “We will respond to the threat of climate change, knowing that the fail
31、ure to do so would betray our children and future generations,“ Obama said. The President pointed out that recent severe weather supplied an urgent impetus for energy innovation and staked the nations economic future on responding to a changing climate. “We cannot cede to other nations the technolog
32、y that will power new jobs and new industries -we must claim its promise,“ Obama said. “Thats how we will maintain our economic vitality and our national treasure our forests and waterways: our croplands and snowcapped(山顶积雪的 )peaks. That is how we will preserve our planet, commanded to our care by G
33、od.“ So what could the President reasonably do to deliver on that vow? Here are ten of their suggestions: Sunset coal with new incentives and regulations. B“Provide incentives to phase out the oldest, most polluting power plants,“ said Robert Jackson, a climate scientist at Duke University. Its alre
34、ady happening, to some degree, as more of the nation transitions to natural gas. Earth scientist Bill Chameides, dean of Dukes Nicholas School of the Environment and a former chief scientist at the Environmental Defense Fund, urges the administration to use its Clean Air Act authority to promulgate(
35、颁布 )carbon regulations for existing power plants like it has for new ones: “Doing that will force fuel switching from coal to natural gas. “ Invest federal stimulus money in nuclear power. CIts hardly a perfect fuel, as accidents like Japans Fukushima fallout have shown, but with safety precautions
36、new nuclear plants can meaningfully offset dirtier types of energy, supporters say. “Nuclear is the only short to medium-term way to really get away from fossil fuels,“ said Peter Raven, President emeritus of the Missouri Botanical Garden. He said the damage done by relentless global warming will fa
37、r exceed the damage done by faults in the nuclear system. Kill the Keystone pipeline. DThe controversial Keystone XL oil pipeline is up for review again by the White House this year. “The first thing he should do to set the tone to a lower carbon economy is to reject the Keystone pipeline,“ said Ray
38、mond Pierrehumbert, a geophysical scientist at the University of Chicago. The pipeline was never going to be a major driver of global emissions, but Pierrehumbert and some other environmentalists say that by killing it the President would send a clear message about Americas intent to ramp down fossi
39、l fuels. Protect the oceans by executive order. E Land use is complicated, but large swaths of oceans can be protected by executive order. Just as President George W. Bush designated the worlds largest marine monument northwest of Hawaii in 2006, Obama could single-handedly protect other areas. Nati
40、onal Geographic Explorer-in-Residence Sylvia Earle said the President should focus on parts of the Arctic that are under U. S. control, putting them off limits to energy production, commercial fishing, and mineral exploration. Marine sanctuaries(禁捕区 )wont stop climate change, but they can give marin
41、e species a better chance of adapting to it by reducing the other man-made threats the animals face. Experiment with capturing carbon. FHuge untapped reserves of natural gas and oil make it unlikely that the U. S. will transition away from fossil fuels in the immediate future. Instead, said Wallace
42、Broecker, geology professor at Columbia Universitys Lamont-Doherty Earth Observatory, we should attack the atmospheres carbon surplus directly. “Obama could make available funds to build and test prototype air capture units“ to capture and store CO2, said Broecker. Removing some carbon from the atmo
43、sphere could buy valuable time as policy makers and scientists explore more permanent solutions. Grow government research for new energy sources. GThe Department of Energy has a nimble program thats tasked with innovative energy research- -the Advanced Research Projects Agency-Energy. The ARPA-E fun
44、ds research in biofuels. transmission, and battery storage, with an annual budget of $275 million. Last year, DOE officials requested at least $75 million more. Increasing funding for ARPA-E, said Rafe Pomerance, former deputy assistant secretary of state for environment and development and currentl
45、y an environmental consultant, “you get new technologies that undercut coal, oil, and gas.“ Plus, he said, you get a competitive advantage if American researchers uncover the next big idea in new energy. Tax carbon. HCongress would have to agree, but many climate experts say that the most meaningful
46、 way to tackle emissions is to set a price on carbon. “We should be asking people to pay the cost of putting carbon into the atmosphere as they buy the fuel.“ said Josh Willis, climate scientist and oceanographer at NASAs Jet Propulsion Laboratory. To gain political support for the idea, Obama would
47、 probably have to show that the tax would help accelerate technology, grow new industries, and pay down the deficit. Dial back the federal governments energy use. IWith more than 1.8 million employees, $ 500 billion in annual purchasing power, and 500.000 buildings to operate, the federal government
48、 has been a leader in reducing energy use since Obama signed a 2009 executive order to cut waste. “I would urge him to keep using the power of government to promote energy conservation,“ said Syndonia Bret-Harte, an Arctic biologist who studies climate change at the University of Alaska, Fairbanks.
49、Build a scientific clearinghouse for climate information. J“I advocate for building a better information system on what is happening and why,“ said Kevin Trenberth, head of the Climate Analysis Section at the U. S. National Center for Atmospheric Research. That involves compiling observations related to climate change from around the world and using the data to refine climate modeling. Think of it as a one-stop, user-friendly websi
