2 . The future in energy production is here. And some of the materials used to supply the energy may surprise you! Companies have developed a way to turn plant wastes and other garbage into fuel. It has been called one of the most promising technologies in energy. And the process is expected to become more common this year.

The American-based company Fiberight is taking the lead in this new form of energy production. Truck loads of garbage are sent to Fiberight’s test plant in southern Virginia. Old vegetables, cardboard boxes and other wastes become something much more valuable through the work done at the factory. 50% of this material is going to be processed for the change of biofuel such as ethanol（乙醇）.

Ethanol makes up about 10 percent of America’s fuel supply. Nearly all of it comes from corn, the food known as maize in some countries. Critics say this creates competition between food and fuel, and raises food prices. Environmentalists say farmers are using more land to plant corn crops. They also say farmers are using more fertilizers and products for killing insects. They say this creates more pollution.

This year, several other fuel production plants are expected to start making ethanol from the cellulose（纤维素） in corn stalks, wheat straw and other plant materials. However, making cellulosic ethanol turned out to be harder than expected. We know how to do that in a lab. The main problem is doing that in a continuous way, cost-effectively on a large scale. Besides, our cars may limit how much the industry can grow. Even if we can begin to produce this cost-effectively, we need to be able to consume it as well. Only a few models of automobiles can operate on high-ethanol fuel. Without more of them, there is only so much gas from garbage that will sell.

6 . My father was in the navy, which meant that my mother was married to both my father and the sea.

7 . Can you be too beautiful? It is hardly a problem that most of us have to bother—as much as we might like to dream that it were the case.

Yet the blessings and curses of beauty have been a long-standing interest in psychology. Do those blessed with shiny faces and an attractive body live in a cloud of appreciation—or does it sometimes pay to be ordinary?

Combing through decades of findings, social psychologists Lisa Slattery Walker and Tonya Frevert at the University of North Carolina at Charlone have reviewed all the evidence to date and their conclusions are not what you might expect.

At the most basic level, beauty might be thought to carry a kind of halo (光环) around it: we see that someone has one good quality, and by association, our deep mind may assume that they have other good ones too.

Even in the courts, a pleasing appearance can work its magic. Attractive criminals are likely to get less strict sentences, or to escape punishment entirely: attractive plaintiffs (原告)， meanwhile, are more likely to win their case and get bigger financial settlements, “it’s an effect seen everywhere,” says Walker.

But if beauty pays in most circumstances, there are still situations where it can have opposite results. While attractive men may be considered better leaders, for instance, hidden sexist prejudices can work against attractive women, making them less likely to be hired for high-level jobs that require power. And as you might expect good-looking people of both sexes run into envy—one study found that if you are interviewed by someone of the same sex, they may be less likely to employ you if they judge that you are more attractive than they are.

More worryingly, being beautiful or handsome could harm your medical care. We tend to link good looks to health, meaning that illnesses are often taken less seriously when they affect the good-looking. When treating people for pain, for instance, doctors tend to take less care over the more attractive people tend to move further away from a beautiful woman on the pathway—perhaps as a mark of respect, but still making interaction more distant. “Attractiveness can convey more power over visible space—but that in turn can make others feel they can’t approach that person,” says Frevert. Interestingly, the online dating website OKCupid recently reported that people with the most beautiful pictures are less likely to find dates than those with less perfect pictures.

Ultimately, Frevert points out that focusing too much on your appearance can itself be harmful if it creates stress and anxiety—even for those already blessed with good looks. “If you are crazy about attractiveness, it may affect your experience and interactions,” she says. It’s an outdated saying, but no amount of beauty can make up for a bad personality. As the writer Dorothy Parker put it so elegantly: “Beauty is only skin deep, but ugly goes clean to the bone.”
