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.

It’s really true what people say about English politeness: it’s everywhere. When squeezing past someone in a narrow aisle, people say “sorry”. When getting off a bus, English passengers say “thank you” rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes unavoidable, and the bus driver is only doing his job. I used to think the same way, without questioning it, until I started traveling to the British Isles and came to appreciate some more polite ways of interacting (交往) with people.
People thank each other everywhere in England, all the time. When people buy something in a shop, customers and retail assistants in most cases thank each other twice or more. In Germany, it would be exceptional to hear more than one “thank you” in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposite to Germans, who would normally think that paying their workers money is already enough.
Another thing I observed during my stay was that English people rarely criticize others. Even when I was working and mistakes were pointed out to me, my employers emphasized (强调) several times that none of their words were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This is also shown in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men. However, I do need to point out here that this applies to English men a bit more than it would to Scottish men! Yes, the latter (后者) are a bit tightfisted.

I was in a terrible mood. Two of my friends had gone to the movies the night before and hadn’t invited me. I was in my room thinking of ways to make them sorry when my father came in. “Want to go for a ride, today, Beck? It’s a beautiful day.”
“No! Leave me alone!” Those were the last words I said to him that morning.
My friends called and invited me to go to the mall with them a few hours later. I forgot to be mad at them and when I came home to find a note on the table. My mother put it where I would be sure to see it. “Dad has had an accident. Please meet us at Highland Park Hospital”.
When I reached the hospital, my mother came out and told me my father’s injuries were extensive. “Your father told the driver to leave him alone and just call 911, thank God! If he had moved Daddy, there’s no telling what might have happened. A broken rib（肋骨）might have pierced（穿透）a lung...”
My mother may have said more, but I didn’t hear. I didn’t hear anything except those terrible words: Leave me alone. My dad said them to save himself from being hurt more. How much had I hurt him when I hurled those words at him earlier in the day?
It was several days later that he was finally able to have a conversation. I held his hand gently, afraid of hurting him.
“Daddy… I am so sorry…”
“It’s okay, sweetheart. I’ll be okay. ”
“No,” I said, “I mean about what I said to you that day. You know, that morning?”
My father could no more tell a lie than he could fly. He looked at me and said. “Sweetheart, I don’t remember anything about that day, not before, during or after the accident. I remember kissing you goodnight the night before, though. ”He managed a weak smile.
My English teacher once told me that words have immeasurable power. They can hurt or they can heal. And we all have the power to choose our words. I intend to do that very carefully from now on.

He 40__ a wrinkled dollar bill, and 41__ glanced back at his table where other students were sitting. With the help of a six-year-old, he tried to make the machine __42 his money.
