With petroleum reserve(石油储量)decreasing, the search is on to replace gas with a cleaner, greener alternative. Though much eco-talk has centered on biofuels from corn and soybeans, the biofuel that looks more likely to replace petroleum comes from a most unlikely source: algae(藻类).
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.controlB.requireC.produceD.grow
小题2:Compared with corn and soybeans, algae_____.
A.may pollute water and soilB.can grow in poor conditions
C.provide much less energyD.need more special care
小题3:According to Paragraph 3, one of the advantages of algae fuel is that ____.
A.it can be used more widelyB.it is easier to produce
C.it needs much less landD.it costs much less money
小题4:Which of the following might be the best title for the text?
A.Environmental ProtectionB.Biofuels from Corn and Soybeans
C.The False Hope of BiofuelsD.A Promising Oil Alternative

The UK has a well-respected higher education system and some of the top universities in the world. But to those who are new to it all, it can be something confusing.
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?

·Make sure you know something about the British social customs. Have a few wine glasses and snacks handy for your housemates and friends.
·Sometimes cups of tea or even sweets can give you a head start in making friends.
·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.

Have you ever been to the beautiful country of Holland and its capital Amsterdam? Anyone who has traveled to Amsterdam would probably agree on one thing: Amsterdam’s story is a tale of two cities -- one during the day and a completely different one at night.
During the day, the largest city in the Netherlands sits quietly on the Amstel River.You can rent a bicycle, visit the Van Gogh or Anne Frank museum, or take a water taxi.But when the sun goes down, the partying begins.In the big clubs and in coffee shops, tourists gather to hang out, talk politics and smoke.
Several areas of the city clearly show the two worlds that rule Amsterdam.And they’re all within a short cab ride of each other.For example, Dam Square attracts daytime sightseers to its festivals, open markets, concerts and other events.Several beautiful and very popular hotels can be found there.And there’s the Royal Palace and the Magna Plaza shopping mall.
But at night party-seekers come to the square.Hip hop or funk music is heard there..So if you come, be ready to dance.The clubs don’t shut down until 4 am.
And while you’re there, check out the various inexpensive ways to tour the city.Don’t worry about getting lost.Although Dutch is the official language, most people in Amsterdam speak English and are happy to help you with directions.And you’ll notice that half the people in the streets are on bicycles they rent.
Amsterdam also has a well-planned canal system.For about 10 dollars, you can use the canal bus or a water taxi to cruise(巡游) the "Venice of the North".
The city has a historic past.One impressive place to visit is the Anne Frank House on Nine Streets.It was there that the young Jewish girl wrote her famous diary during World War II.Visitors can view Anne’s original diary and climb behind the bookcase to the room where she and her family hid from the Nazis for two years.
