Problem: 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.

Problem: Article: Around three forty-five on a rainy Saturday morning, I was woken up by the sound of my pager beeping. As a volunteer firefighter and emergency medical technician, I can never count on a full night of sleep. I pulled myself out of bed and went toward the desk to grab my radio. Our crew was being sent to a nearby home where a man was in cardiac arrest . We found the man lying on the kitchen floor with his wife beside him. We rushed the patient to the hospital, but despite our efforts, we were unable to save his life. In my line of life, I rarely get any recognition from the patients we treat, or from their loved ones. But that night, a man's wife approached us, and through her tears, whispered, "Thank you." Then she hugged each of us. She knew we answered her late-night call for help, even though the ending was not positive. There is something deeply rewarding about helping people in these circumstances. Sometimes, I'm able to make their worst day a bit better: like seeing the tears of an injured child turn into a smile when I gave him an interesting toy; or watching a terrified mother's screams turn into tears of joy when she realized her baby was going to be fine. Experiences like these allow me to see the impact my work has on others. At the same time, I also know the effect _ has had on my own life. As a teenager, I felt awkward when my dad hugged me and said, " I love you, my dear son." I was equally uncomfortable and responded, "I love you." But then I imagined him lying on the kitchen floor that rainy night and realized that my opportunity to say those three words could---at any moment---be taken away forever. Now, I extremely treasure the moment when my father says those three words to me. I've learned to appreciate every relationship I have, to tell people I care about them, and to never take anything in life for granted.
