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.
Answer: whether mood affects their learning ability
Solution: Researchers did experiments on kids in order to find out _ .
Why? It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment.

New input: Article: Hawking Fever Hit prefix = st1 /China Hawking has left much for Chinese to think about. British physicist Stephen Hawking,possibly the world's most famous scientist after Albert Einstein,gave lectures in Zhejiang and Beijing in August. An illness left him unable to move any part of his body except for the three fingers.But his continuing efforts in the field of science have made many young people take him as their idol. His books,such as A Brief History of Time,become bestseller in Chinese bookstores. "Hawking helps people expand their horizons and become interested in science,"said Pan Yunhe,president of Zhejiang University. Indeed,experts don't think it likely that Hawking's lectures and profound ideas will be easily understood by the average persons.But he has certainly sowed the seeds of science among many young people. And the "Hawking fever" cause by his visit has made people ask:How can China produce more top scientists like Hawking? "Nurturing top scientists will take as much as work to change society as to educate the scientists themselves,"said Zhang Fan.Zhang has studied in the UK since 1999 and will be a sophomore at Trinity College in October. In Britain,Zhang said,teacher inspire students to have a general understanding of the subjects they are interested in.and they encourage students to develop new ideas,which helps them to nurture their creativity. In China,the Ministry of Education has encouraged schools to provide quality education to tap students' potential. "I hope teachers will pay more attention to helping us use our imaginations and solve problems on our own,"said Lu Jie,a Junior Three student in Sanfan Middle School in Beijing.
