Example: 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.

The car provides the most comfortable and cheapest from of transportation. With a car people can go to any place without spending a lot of money. The second reason that cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long distance trains have never been as common in the United States as they are in the other parts of the world. Nowadays there is good system of air service provided by planes. But it is too expensive to be used frequently. The third reason is the most important one. The American spirit of independence is what really made cars popular. Americans don't like to wait for a bus, or a train or even a plane. They don't like to have to follow an exact schedule. A car gives them the freedom to plan their own time. And this is the freedom that Americans want most to have. The gas shortage has caused a big problem for Americans. But the answer will not be a bigger system of public transportation.
