Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goer's life.

    But there may be a benefit to doing so, as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests.

    The research found that people who watched a movie in 3D improved cognitive (认知) skills, compared to those who watched it in 2D.

    The research was led by neuroscientist(神经学家) Dr Patrick Fagan from Goldsmiths University in London. More than 100 people took part in the experiment, where participants watched Disney film Big Hero 6 in either standard format or RealD 3D.

    They also carried out a brain-training-style test before and after seeing a section from the film. The test covered memory, reaction times and cognitive function and the results were compared later.

    According to the research, which was carried out in partnership with science group Thrill Laboratory, participants experienced a 23 percent increase in cognitive processing, as well as an 11 percent increase in reaction times.

    Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain power in the future.

    "These findings are more significant than you might think," he said. "It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life. There has never been a better time to look at ways to improve brain function. The initial results of this study show that 3D films may potentially play a role in slowing this decline."

    A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed heightened (加强的) activity when watching 3D. According to the results, participants were seven percent more engaged with what they were watching, adding to argument that 3D movies are more like watching real-life—something Professor Brendan Walker from Thrill Laboratory agreed with.

    "As Professor Brendan Walker's test concluded, 3D films are more attractive and heighten the senses — this, in turn, makes the brain run at quicker speeds," Dr Fagan said.

    Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight.

    Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores (胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

    When you are travelling in Thailand, which means of transport is the best choice?

    You can rent a variety of motorbikes or bikes in Thailand. It seems to be very popular in most of the beaches and islands along the places in the north. The most popular bikes are the little 125 cc Honda Dream which you can get for about 150 baht (铢) a day or as little as 3,000 baht per month, making it the cheapest way to tour Thailand for the people from other countries.

    Sometimes you will have to go somewhere by taxi. When you are in cities in Thailand, especially in Bangkok, always remember to get a taxi that is traveling on the roads. Some drivers outside hotels refuse to use the meter (计程表). They will ask a price which is several times the price when they use the meter!

    The quality of the roads in Thailand is generally pretty good, so renting cars is another way to get around. The big car rental companies may offer you slightly older cars at a very reasonable (合理的) price. It is a little surprising considering that the cost of buying a car in Thailand is more than that in the West. Petrol is also reasonably priced in Thailand, more expensive than American prices, but much cheaper than what is paid in Europe. In the past, Bangkok could be a difficult place to drive in—signs were generally in Thai only, making it a hard job to find exactly where you were by looking around. But now, the situation is improved. In a lot of places, even the farthest corners of the country, street signs are in both Thai and English.

    “Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American's exports soon after it went on the air in New York in 1969.

    In the United States more than six million children watch the program regularly. The viewers include more than half the nation's pre-school children, from every kind of economic, racial, and geographical group.

    Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.

    Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional（偶然的）viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.

    The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.

    Why has “Sesame Street” been so much more successful than other children's shows? Many reasons have been suggested. People mention the educational theories（理论）of its creators, the support by the government and private（私人的）businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.

Emilia Dobek traces her interest in space and the universe back to third grade when she and her father watched a blood moon—a total lunar eclipse (月蚀)—on the roof of their house.

    Now a seventh-grader at East Prairie Elementary School, Dobek recently won the national Discovery Education Lockheed-Martin Beyond Challenge by designing a space station for travelling to Mars.

    She says that night watching the lunar eclipse started a strong desire in her that has yet to run out of fuel. So when her teacher Andrea Smeeton received information about the national challenge, Smeeton said she immediately had one student in mind.

    "I knew she would love the challenge and that she would go way beyond in her search," Smeeton said. "She immediately started researching bone density (密度) of astronauts and how to have food on Mars."

    "My design will ensure the safety of the astronauts but also make sure their comfort is out of this world," Dobek says.

    Dobek's design calls for building the MSS or Mars Storage Station to put the supplies in. It also includes the SGF or Self-Crowing Farm, and she details how it would work with the elements on Mars.

    Then there is physical and leisure activity for the astronauts under Dobek's design. A simulation (模拟装置) allows astronauts to choose their exercise machine and virtual (虚拟的) reality environment. Rooms have circular ceilings so astronauts will be able to watch downloaded shows and even see places on Earth, such as their homes.

    "I want to tell other kids to follow their passions." Dobek said. "Whatever they want to do they should push for it and always try their best."

    "I'm the smartest kid in class." We all want our kids to be self-confident, but unrealistic perception(认知) of their academic abilities, a new study finds, damage a child's relationship with others in the classroom: The more one student feels unrealistically superior(更好的) to another, the less the two students like each other.

Katrin Rentzsch of Bamberg University in Germany first became interested in the effects of such self-perception when she was studying how people became labeled as nerds(书呆子). "I really got interested in the question of whether it's OK to boast(吹嘘) about achievements," she says.

    This line of thinking led her towards something psychologists call "self-enhancement" －when a person feels unrealistically superior to someone else. So Rentzsch and her colleague Michela Schroder-Abe decided to take a closer look at how such self-enhancement affects relationships, so they turned to the eighth-grade classroom, somewhere they could measure differences between actual academic performance, and social popularity. The 358 students came from 20 eighth-grade classes in schools in southeast Germany.

    The researchers asked each student to rate their classmates, in terms of their likability and of their feelings of academic superiority. They then compared those ratings with the students' grades in math, physics, German and English. Importantly, they conducted the analysis at two different social levels: "habitual"－the way people act in general, and "relationship"－the way someone acts around a specific individual.

    In future work, Rentzsch would like to look at these effects on adults, perhaps specifically in team work. She's also interested in self-enhancement beyond academic achievements, for example physical attractiveness. And another question to explore is why students overestimate their academic abilities. Perhaps it is because of too much praise from their parents or teachers.
