Teacher: Now, understand the problem? If you are still confused, see the following 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.

Now, solve this instance: Article: The type of things we remember are different. Although we tend to remember good things in our lives, bad things have a way of on us. One such thing I remember happened when I was 10 years old. I decided to ride my bicycle over a near-by stream. I carefully planned the adventure, and asked my friends to go there and have a watch. This was going to be my moment! I started riding down the hill, picking up speed and then pulled up on the at the precise moment and landed face-first into the muddy stream! That painful moment is one that I will never forget. As long as I live, I will remember the pain and embarrassment at that moment. When we do something stupid or thoughtless, it has a way of sticking with us. Fortunately, good momories have a way of over-riding the bad ones. I have memories that I gladly remember, like what happened today. I had my first conversation with my son today. It was not anything . It was a simple connection between father and son. It was one of those bonding moments that you can't plan or force. They just happen on their own. I was walking into the living room where my son sat in bed watching television attentively. Then he looked up at me and pointed to the television and something. I asked him if he was watching and he nodded his head and said,"Yes". It was at that moment that his eyes lit up and it was as if we both realized we had communicated. And how happy I was! Sure, at eighteen months, he probably did not realize what communication was like, but his joy at that moment was evident. It was a moment I will remember all my life. Good or bad, memories can last a lifetime. As for an unpleasant memory, though we can't forget it we can get lessons from it and it is like a mirror that will warn us against making such mistakes again. As for a good memory, we should try our best to enjoy it during our lifetime. Such moments are the treasures that we store up forever.
