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.

New input: Article: The adder is the only poisonous snake native to Britain. Adders have the most highly developed poison injecting mechanism of all snakes, but they are not aggressive animals. Adders will only use their poison as a last means of defence, usually if caught or trodden on. No one has died from adder bites in Britain for over 20 years. By faar the most common smake in Britain is the adder. In Scotland, in fact, there are no other snakes at all. The adder is also the only British sanke with a poisonous bite. It can be found almost anywhere, but prefers sunny hillsides and rough open country, including high gournd. In Ireland there are no snakes at all. Most people regard snake bites as a fatal misfortune, but not all bites are serious, and very few are fatal . Sometimes attempts at emergency treatment turn out to be more dangerous than the bite itself, with amateurs heroically, but mistakenly, trying do-it-yourself surgery and other unnecessary measures. All snakes have small teeth, so it follows tha tall snakes can bite, but only te bite of the adder presents any danger. British snakes are shy animals and are fare more frightened of you than you could possibly be of them. The adder will attack only if it feels threatened, as can happen if you take it by surprise and step on it accidentally, or if you try to catch it or pick it up, which it dislikes intensely. If it hears you coming, it will normally get out of the way as quickly as it can, but adders cannot move very rapidly and may attack before moving if you are very close. The effect of a bite varies considerably. It depends upon severa things, one of which is the boidy-wight of the person bitten. The bigger the person, the less harmful the bite is likely to be, which is why children suffer far more seriously from snake bites in Britain ,and thought these bites can make soime pepe very ill, thre are probaably just as many cases of bites having little or no effect, as there are of serious illess.
