Q: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Q: Article: The consumer  plays a very important role in the global efforts to reduce C02emissions . Households use one third of the final energy and produce around two thirds of city waste in the European Union. Besides,housing, food,and private transport make up almost 80% of environmental pressures. Therefore there's no doubt that consumers can make a real difference in fighting climate change. To direct consumers towards more environmentally-friendly decisions,we need clear and simple instructions to guide consumption behavior. Actually, two thirds of consumers find it hard to figure out which products are better for the environment, for 58% Europeans think that many businesses just pretend to be green so as to charge higher prices. Thus industry should work harder to give consumers more information about the carbon footprint of their product. For example, inform customers of products made from materials that are recycled,renewable, and/or less carbon-intensive.  People prefer high-quality products that will last long and won't go out of style, though they might sometimes cost more, especially in time of crisis. Firms that make durable  or recyclable products cause people to behave more responsibly, which may help put an end to our "throw-way" culture. However, it is not enough to remind people of green products. It's more important to direct people to follow a practical lifestyle model. Regulations alone cannot achieve this purpose. We call for good business communities to create a loyal group of "sustainable consumers".
