Biofuels
Biofules have been around as long as cars have．At the start of the 20th century, Henry Ford planned to fuel his Model Ts with ethanol(乙醇)．But discoveries of huge petroleum deposits(储量)kept gasoline and diesel(柴油)cheap for decades, and biofucls were largely forgotten．However, with the recent rise in oil prices, along with growing concern about global warming caused by carbon dioxide emissions, biofuels have been regaining popularity．
Gasoline and diesel are actually ancient biofuels．But they are known as fossil fuels because they are made from plants and animals that have been buried in the ground for millions of years．Biofuels are similar, except that they're made form plants grown today．
Much of the gasoline in the United States in blended with a biofuel-ethanol．Countries around the world are using various kinds of biofuels．For decades, Brazil has turned sugarcane into ethanol, and some cars there can run on pure ethanol rather than as additive to fossil fuels．
On the face of it, biofuels look line a great solution．Since plants absorb carbon dioxide as they grown crops grown for biofuels should suck up about as much carbon dioxide as comes out of the tailpipes of cars that burn these fuels．And unlike underground oil reserves, biofuels are a renewable resource since we can always grow more crops to turn into fuel．
Unfortunately, it's not so simple．The process of growing the crops, making fertilizers and pesticides, and processing the plants into me!consumes a lot of energy．Also, because much of the energy used in production comes from coal and natural gas, biofiiels don't replace as much oil as they use．

It’s likely that everything you learned about America’s ancient history is wrong.
The new book, 1491, completely changes our understanding of the Americas before the arrival of Columbus in 1492.

NEW YORK (AP) — In a report, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine.
That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised that the growth wasn’t higher than it had been expected.
“Yes it’s doubled, but it’s still the case that there’s a big chunk of Internet users who have never done this simple act of connecting their names with search engines,” she said. “Certainly more and more people have become aware of this, but I don’t know it’s necessarily kept pace with the amount of content we post about ourselves or what others post about us.”
About 60 percent of Internet users said they aren’t worried about the extent of information about themselves online, although they are increasingly concerned over how that data can be used.
Americans under 50 and those with more education and income were more likely to self-Google---in some cases because their jobs demand a certain online persona(形象).
Meanwhile, Pew found that 53 percent of adult Internet users admit to looking up information about someone else, famous people not included.
Often, it’s to find someone they’ve lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common.
Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating.
In many cases, the search is not harmful, done to find someone’s contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies(破产) and divorce proceedings. A similar number have searched for someone else’s photo.
Pew also found that teens were more likely than adults to limit the range of people who can see their information at an online hangout like Facebook or News Corp.’s MySpace, contrary to conventional wisdom.
“Teens are more comfortable with the applications in some ways, (but) I also think they have their parents and teachers telling them to be very careful about what they post and who they share it with,” Madden said.
Mary Madden was surprised at the result that ______.
A. fewer and fewer adult Internet users are looking for information about themselves
B. the number of adult Internet users looking for information about themselves has doubled
C. more adult Internet users should have looked for information about themselves
D. so many people don’t know how to connect their names with search engines
According to the report some people haven’t looked for information about themselves because ______.
A. they are not rich enough to get a computer
B. they are not well educated
C. they don’t know they can look for their own information on the Internet
D. they think it unnecessary to look for their own information on the Internet
Which group of people are more likely to look for their own information on the Internet?
A. Teens. B. Women. C. The old. D. The educated.
People look for others’ information on the Internet mainly to ______.
A. see what they are doing B. find someone they have lost touch with
C. have a look at their photos D. know their personal affairs
-----I just heard that the tickets for tonight’s show have been sold out. -----Oh no! ______.
A. I was looking forward to that B. It doesn’t matter
C. I know it already D. It’s not at all interesting
