Article: Mom was right!If you say thank you,for even the smallest gift or slightest show of kindness,you'll feel happy. Gratitude ,says Robert A.Emmons,a professor of psychology at the University of California,is an important element of happiness.In his recent book,Thanks!,Emmons uses the first major study on gratitude to prove mom's point.In acknowledging and developing this muchignored expression of thankfulness,he explains how people have benefited--even improved their health. As one of the leading scholars of the positive psychology movement,he admits gratitude may be difficult to express.He advises you to begin by admitting that life is good and full of events and elements that make daily existence a wonder.Second,recognize that the source of life's goodness is more than just you.That source may be your mom,a friend,partner,child,colleague at work or play,or any combination of these. Gratitude is always otherdirected,notes Emmons.You can be pleased or angry with yourself and feel guilty about doing something wrong,but you can never be grateful to or for yourself. Expressing gratitude shouldn't be a reaction;it should be a state of mind.To feel grateful when life is a breeze and you have more than you need is easy.To feel grateful in time of crisis--anger,hatred and bitterness--is easier.Also,too many people are aware of life's blessings only after these are lost.The voices expressing gratitude from his studies of individuals are many. It's crisis and chaos--danger,disease,disability and death--that bring many individuals to realize just how dependent they are on others.Yet it's the way each of us begins life and ends it.It's too bad that so many people waste those decades in between labouring under the illusion they are selfsufficient,says Emmons. To enable and embrace gratitude,Emmons encourages the readers of Thanks! to keep a gratitude diary.He even provides easytofollow directions on how to practise and develop gratitude. I'm not a reader or advocate of selfhelp books,but I am thankful for the reference I found in a newspaper article to the research Emmons was conducting on gratitude involving organ donors and recipients .The chance discovery led me to this book. Mom implied that kindness seems to find its way back to the giver because life really is all about giving,receiving and repaying.So I'll pay attention to her professional advice and say:Thank you,professor Emmons.
Answer: Gratitude is important to happiness.

Article: In October on the east coast of Australia migrating humpback whales pass very close to the shore. With the help of Max Egan, we went to film them near Byron Bay. It was extremely exciting to spot the little puffs of spray on the horizon. When migrating, the whales can be traveling at speeds of about 12km/h and can dive under anywhere between five and forty minutes, but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting. As the whales break the surface like submarines , the water spills off their broad dark backs and huge tails. Then, with a powerful down stroke, they dive back into the depths of the sea, leaving just a smooth glassy patch of water or "footprint" on the surface to show where they had been. One day we had traveled up and down the shore and far out to the sea in search of whales, but the horizon was deserted. There was no report of whales in the area so we decided to test out Max's new, highly sensitive hydrophone and the result was astonishing. As soon as the hydrophone was in the water, we found ourselves listening to the most beautiful voices. What may have seemed like a vast empty ocean was filled with the singing of whales. It is the males which sing, as they migrate between feeding and breeding grounds. No one knows for sure what the purpose of these songs is, whether they are love songs to the females or warnings to other males to stay away. It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune and quickly adopt any new songs they hear.
Answer: The songs of whales.
Which finding about whales is beyond the writer's expectation?

Article: It was a long week for Amanda at school. She stayed after school to work on a special project three days in a row. When she got home on Friday, she dropped into the chair with a sigh. "What's going on, Amanda?" her dad asked as he was reading the newspaper. "I have to create a webpage for my technology class, and it is taking a lot more time than I thought it would," Amanda answered. Her dad looked over his newspaper and asked Amanda what the webpage was about. "It's about the difference between newspaper news and Internet news," Amanda said and added, "I have to provide information, examples and illustrations ." "Sounds tough; do you have someone to help you?" her dad asked. "I have a partner named Zach," Amanda replied. "We did research on the Internet today and found some pictures to use." Then Amanda explained to her father the main differences: newspaper news is printed on paper, and Internet news is published online; newspaper news is only available once a day, and Internet news is published almost as soon as the news happens; many newspapers don't even print a daily paper, and Internet news is published around the clock. Amanda's dad asked, "Which type of news do you like better?" "I like Internet news better because I like to learn about the news when it happens," she answered. Her dad said, "I still like newspaper news better because I like to hold the paper in my hands and turn the pages." Amanda dropped into her chair again and said, "You are so old school, Dad."
Answer: She made a mistake in her technology class.
Why did Amanda sigh when she came home?
