Problem: Article: Homework can put you in a bad mood , 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.

Problem: Article: Food safety will become the food industry's key target as the nation tries to adopt international food standards. The National Development and Reform Commission, the Standardization Administration of China, the Ministry of Agriculture and six other departments announced their 2004-05 development programme for national food standards over the weekend. China is conducting a rectification within two years. Inspectors will search for all known banned materials in food production. To reduce trading barriers, China will raise the ratio of adopting international standards in the food industry to 55 percent from today's 23 percent. "Safety is the first consideration for anything entering people's mouth followed by its nutritious value," said Hao Yu, secretary-general of the National Food Industry Standardization Technique Committee. He added the usage of food addictives will be a major field for consideration in setting the new standards. On-the-spot checks during the past two years have shown the abuse or misuse of addictives in food production and processing has become the biggest threat to food safety. In one case, talcum powder was found in flour products, which is outlawed according to national food standards. "At present there are no methods or standards to test the content of talcum powder in flour," said Shang Yan'e, an official with the national watchdog on grain and oil inspections. Under the guidelines, all banned addictives will be recorded as inspections increase, Relevant departments have allocated funds to conduct risk evaluations on current food addictives to fix the limits of their usage. China will adopt international advanced techniques and standards so as to find out the harmful materials in food within a shortest period.
