But what truth is there in the saying? Is there a relation between money and happiness? 1Humans are very sensitive to change. When we get a rise, we really enjoy it. But some studies have shown that in North America, additional income beyond 75,000 dollars a year stops impacting day-to-day happiness.2They often end up spending all the money, going into debt, and experience ruined social relationships.So surely money can't really buy happiness. Well, recent studies suggest that the problem may actually be in the way that we spend money.3Studies show that people who spend their money on others feel happier. As for the people who spend money on themselves, their happiness is unchanged.40ne experiment showed that instead of an organization writing a large check to a charity, dividing the amount up among employees, allowing them to contribute to a charity of their choice, increased their job satisfaction. Similarly, individuals that spend money on each other, as opposed to themselves, not only increase job satisfaction, but improve the team performance.5Interestingly, the specific way money is spent on others isn't important. Spending something on others is the important aspect of increasing your happiness.

D. And if so, how can we use it to our advantage?

【题目】One advantage of the Internet is shopping conveniently online for clothes; one disadvantage of the Internet is also shopping conveniently online for clothes.

“Nothing fits,” said Lam Yuk Wong, a senior in electrical and computer engineering at Rice University. “Everyone says this. They order clothes and they don’t fit. People get very unhappy.”

Wong and her design partner, Xuaner “Cecilia” Zhang, are Team White Mirror, creators of what they call a “virtual (虚拟)fitting room”. Their goal is simple and consumer-friendly: to let online clothing shoppers have a perfect fit and a perfect look when shopping every time. Both women are from China, Wong from Hong Ko ng and Zhang from Beijing. They both order most of their clothing online. They got the idea from their own experience as consumers and from listening to the complaints of friends and relatives. “They say, ‘The color is wrong’ or ‘I got the right size but it still does not fit.’ We want to make it like you’re in the store trying on the clothes,” Zhang said.

Using a Kinect developed by Microsoft for use with its Xbox 360 video game player, Zhang scans Wong and turns her image into, in effect, a virtual model, keeping Wong’s dimensions (尺寸), and even her skin and hair color. “We put the clothes on the shopper’s 3-D body models and show how they look when they are dressed,” Wong said. So far, Wong and Zhang have adapted the software to show dresses and shirts, and they are now working on shorts.

Asked if she thought men as well as women might be interested in using their virtual fitting room, Wong said, “I think their wives will care about this, so it will also be important to men.”
