On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA．DNA is something that everybody has, and it tells the body what to do．DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own．

People have been trying to understand the human body for a long time．In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family．It is because of small things named “genes” in our body．In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language．

In 1961, Marshall Nirenberg and Johann Mattaei found a message in DNA showing how DNA tells the cell (细胞) to build its parts．Scientists have now found all the words in the DNA map, but we still do not understand what they all do．By understanding what just one “word” means, we can help save more people from several illnesses．

Most people hope that this will help make better medicine and help sick people．Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs．Man will have to meet a lot of trouble if DNA technology (技术) isn’t limited in use．

A psychologist（心理学家） walked around a room while teaching stress management to the audience. As she raised a glass of water, everyone expected they’d be asked the “half empty or half full” question. Instead, with a smile on her face, she asked: “______?”

Answers came out from 8 oz（盎司） to 20 oz.

She replied, “The real weight doesn’t matter. It depends on how long I hold it. If I hold it for a minute, it’s not a problem. If I hold it for an hour, I’ll have an ache in my arm. If I hold it for a day, my arm will feel numb. In each case, the weight of the glass doesn’t change, but the longer I hold it, the heavier it becomes.”

She continued, “The stresses and worries in life are like that glass of water. Think about them for a while and nothing happens. Think about them a bit longer and they begin to hurt. And if you think about them all day long, you will feel numb-unable to do anything.”

It’s important to remember to let go of your stresses. As early in the evening as you can, put all your burdens down. Don’t carry them through the evening and into the night. Remember to put the glass down!
