[Q]: 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.
[A]: What is the text mainly discussed?


[Q]: Article: One of the best things you can do for your health is to drop a few pounds. Or maybe morethan a few pounds.  Being overweight increases your danger of heart disease, high blood pressure, cancer,,the list seems almost endless. You'd better find several simple things you can do on a daily basis  such as making rules of eating more vegetables and less fat and getting more physical activities.  After breakfast, make water your primary drink. At breakfast, go ahead and drink orange juice. But throughout the rest of the day, focus on water instead of juice or soda. The average American consumes  an extra 245 calories a day from soft drinks. That's nearly 90,000 calories a year -- or 25 pounds! And research shows that neither the calories nor sugary drinks give you a sense of fullness the way that food does.  People take only 2,000 to 3, 000 steps a day. Adding 2,000 steps will help you keep your present weight and stop gaining weight. Adding more than that will help you lose weight.  Eat five or six small meals or snacks a day instead of three large meals. A 1999 South African study found that when men ate parts of their morning meal at intervals over five hours, they consumed almost 20 percent fewer calories at lunch than when they ate a single breakfast.

[A]: Where is the passage probably taken from?


[Q]: Article: The monitor "watches" deceleration (=slow down) and distance from a light - and "guesses" which cars are likely to break the Highway Code. Most importantly, the software can provide two seconds' warning if someone else is about to shoot across a crossroads - enough time for other drivers to hit the brakes. Jonathan How, the Professor of Aeronautics and Astronautics at MIT, says "smart" cars of the future may use the system to help drivers foresee and avoid potential accidents. The researchers tested the algorithm on data collected from an intersection   in Virginia, finding that it accurately identified potential violators within a couple of seconds of reaching a red light -- enough time, according to the researchers, for other drivers at an intersection to be able to react to the threat if alerted  . Compared to other efforts to model driving behavior, the MIT algorithm brought fewer false alarms, an important advantage for systems providing guidance to human drivers. The researchers report their findings in a paper that will appear in the journal IEEE Transactions on Intelligent Transportation Systems. 
 Answer: It will raise the alarm when the driver breaks the traffic rules.
