Article: "My kids really understand solar and earth-heat energy," says a second-grade teacher in prefix = st1 /Saugus,California, "Some of them are building solar collectors for their energy course." These young scientists are part of City Building Educational Program (CBEP) , a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading ,writing and math skills , and more . The children don't just plan any city . They map and analyze the housing , energy , and transportation requirements of their own district and foretell its needs in 100 years . With the aid of an architect who visits the classroom once a week , they invent new ways to meet these needs and build models of their creations . "Designing buildings of the future gives children a lot of freedom," says the teacher who developed this program. "They are able to use their own rich imagination and inventions without fear of blame , because there are no wrong answers in a future context . In fact , as the class enters the final model-building stage of the program , an elected "official" and "planning group" make all the design decisions for the model city , and the teacher steps back and becomes an adviser ." CBEP is a set of activities , games , and imitations that teach the basic steps necessary for problem-solving ; observing , analyzing, working out possible answers , and judging them based on the children's own standards . Question: The children feel free in the program because_. Options: A: they can design future buildings themselves B: they have new ideas and rich imagination C: they are given enough time to design models D: they need not worry about making mistakes

Article: Global warming may or may not be the great environmental crisis of the 21st century, but--regardless of whether it is or isn't -- we won't do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed. Al Gore calls global warming an "inconvenient truth," as if merely recognizing it could put us on a path to a solution. But the real truth is that we don't know enough to relieve global warming, and--without major technological breakthroughs--we can't do much about it. From 2003 to 2050, the world's population is estimated to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. But that's too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world's poor people to their present poverty and freeze everyone else's living standards. With modest economic growth, energy use and greenhouse emissions more than double by 2050. No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they're "doing something." Consider the Kyoto Protocol . It allowed countries that joined to punish those that didn't. But it hasn't reduced CO2 emissions (up about 25% since 1990), and many signatories didn't adopt tough enough policies to hit their 2008-2012 targets. The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it. The trouble with the global warming debate is that it has become a moral problem when it's really an engineering one. The... Question: The author believes that, since the signing of the Kyoto Protocol, _ . Options: A: politicians have started to do something to better the situation B: few nations have adopted real tough measures to limit energy use C: reductions in energy consumption have greatly cut back global warming D: international cooperation has contributed to solving environmental problems

Q: Read the article and select the best answer. Article: The capsized accident which happened in Yangtze River on June 1st, 2015 shocked the whole country.There are so many people related to this accident.Zhang Shunwen, the captain of the vessel , has been probably the person being mostly discussed now. Born in 1963, Zhang has been working on this ship for 35 years and became captain of it in 2007.Until the accident, Zhang was regarded as an effective captain and his experience as a sailor was flawless with numerous awards. Zhang Shunwen said the wind was coming from the South, and the wind then was about three to four grade.He first tried to ride the ship northward on the leeside in an effort to counter it with the vessel's speed.However, the wind suddenly gathered speed and he lost control of the ship."We couldn't fend off the wind even if we made a full left turn." he said. Zhang escaped alive and is under watching by police, although he has not yet been accused of any wrongdoing. Every person has his opinion toward this kind behavior of police. Some of them think of it to be improper because the captain himself is also a victim in this accident, what's more, his wife, who also boarded on this boat, remains missing now. While others are in support of this action, to them, it is the captain who should shoulder the responsibility. For me, I agree with the former. Because the captain has made every effort to deal with the accident. Question: What's the author's attitude towards Zhang? Options: A: Indifferent. B: Hateful. C: Sympathetic. D: Hopeful
A: C

(Question)
Read the article and select the best answer. Article: It is probably the strangest sport anyone has ever invented. And at first sight, it looks like the easiest. Competitors have to do two things. The first is to stand still. The second is to place their hand anywhere on the body of a car, and keep it there. This is where things start getting difficult. Lots of other people are doing the same thing. And the winner of the "handathon" contest is the person who can carry on doing it for the longest time. That person gets to own the car. It still seems to be an easy thing to do. At the beginning it is. Anyone can stand still. But when the contest has been going for four or five days, standing still seems like the most difficult job in the world. And keeping the hand in place over this time becomes an act of serious attention. After a few days, the hand seems to belong to someone else--someone who wants to go home and get some sleep. Competitors are allowed to take a five-minute break every hour to eat, drink or do whatever else is necessary. No one is allowed to lean on the car for support. Winners need to be able to show great powers of attention. They also need to be able to develop special skills. Maybe the popularity of the handathon is due to the fact that it is not necessary to be a trained athlete to enter. Entrants in the Longview handathon certainly don't seem to do much preparation. Most say they will prepare by "getting lots of sleep". Others say they will "eat healthy food" or "pray for success". The whole event gives ordinary people the chance to do something interesting and win something at the end. Handathons are competitions, but there is little rivalry between the competitors. They help each other out and keep each other's spirits up. People who drop out early return with food, drink and encouragement for those still standing. Question: The reason why the sport is called "handathon" is probably that _ in the competition. Options: A: people cover a long distance B: people keep hands in place long C: people wave hands as long as possible D: people do the same thing as in marathon
