What is your favorite color Do you like yellow, orange or red If you do, you must be an optimist (乐观者), a leader, an active person. Do you prefer grays and blues Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. At least this is what psychologists (心理学家) tell us. They have been seriously studying the meaning of color preference (爱好), and the effect that colors have on human beings. They tell us that we don’t choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.
A yellow room makes us feel more cheerful and more comfortable than a dark green one. On the other hand, black is depressing. Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.
Remember that you will know your friends and your enemies better when you find out what colors they like and dislike. And don’t forget that anyone can guess a lot about your character when you choose a piece of handkerchief.

The main idea of paragraph 2 is（　）

A:colors may have effect on our work and study B:colors do have effect on our moods (情绪) C:light and bright colors make people happy D:factory workers can work better in a bright room

Passage Three
Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them; our purpose is to prepare them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough just to choose the first system of education one finds, or to continue with one’s old system of enducation without examining it to see whether it is in fact suitable or not.
In many modern countries it has for some time been fashionable to think that, by free education for all--whether rich or poor, clever or stupid--one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider "low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.
But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor, We can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.
In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one’s work, or to scorn someone else’s. Only such a type of education can be called valuable to society.

"Low" work here means （）

A:work with brains B:work with hands C:the work that people do at home D:the work scientists do in the lab

Better Solar Energy Systems: More Heat, More Light Solar photovoltaic（光伏的）thermal energy systems,or PVTs, generate both heat and electricity, but until now they haven’t been very good at the heat-generating part compared to a stand-alone solar thermal collector. That’s because they operate at low temperatures to cool crystalline（晶体的）silicon solar cells, which lets the silicon generate more electricity but isn’ta very efficient way to gather heat. That’s a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it’s also a space problem: photovoltaic cells can take up all the space on the roof, leaving little room for thermal applications. In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen’s University, Canada. Most solar panels are made with crystalline silicon, but you can also make solar cells out of amorphous（非晶体的）silicon, commonly known as thin-film silicon. They don’t create as much electricity, but they are lighter, flexible, and cheaper. And, because they require much less silicon,they have a greener footprint. Unfortunately, thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect. "That means that their efficiency drops when you expose them to light—pretty much the worst possible effect for a solar cell," Pearce explains,which is one of the reasons thin-film solar panels make up only a small fraction of the market. However, Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new type of PVT. You don’t have to cool down thin-film silicon to make it work. In fact, Pearce’s group discovered that by heating it to solar-thermal operating temperatures, near the boiling point of water, they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector, they also found that by baking the cell once a day, they boosted the solar cell’s electrical efficiency by over 10 percent. Thin-film solar panels do not sell well on market because

A:their advantages are not well-recognized. B:they do not work well if exposed to light. C:they need improving in appearance. D:they are not advertised.
