Algae, like corn, soybeans, and other crops, grow via photosynthesis(光合作用)and can be processed into fuel oil. However, they yield 30 times more energy than land crops such as soybeans, according to the U.S. Department of Energy. Many algae species also can grow in saltwater and polluted water—while corn and soy require arable(适于耕种的) land and fresh water that will be in short supply as the world’s population balloons.
“If you replaced all the diesel(柴油)in the U.S. with soy biodiesel, it would take half the land mass of the U.S. to grow those soybeans,” says Matt Caspari, chief executive of Aurora Biofuels, a Berkeley, Calif-based private firm that specializes in algae oil technology. On the other hand, the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States, it would require only l5, 000 square miles, which is a few thousand miles larger than Maryland (12,407 squaree miles), the 42nd state in land area.
Another advantages: Because algae can be grown just about anywhere in a closed space, they’re being tested at several power plants across the nation as a carbon absorber. Smokestack emissions(烟囱排放物)can be pumped directly into the ponds, feeding the algae while keeping greenhouse gases out of the atmosphere.
Although processing technology for algae fuel—also known as “oilgae” in some environmentalist circles —is improving, it’s still years away from reaching your local gas pump. “It’s just a question of cost, because no large-scale facilities have been built yet,” Caspari says.
小题1:The underlined word “yield” in Paragraph 2 can be replaced by “_______”.
A.control | B.require | C.produce | D.grow |

October is usually the busiest month in the academic calendar (学习日程表). Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life.
However, having just left the comfort of home and all your friends behind, meeting lots of strangers in big halls can be uneasy. Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you are worried about starting their university social life. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.

·The more active you are, the more likely you’ll be to meet new people than if you’re someone who never leaves his rooms.
·Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.
