Since 1950, the amount of information about the nutrition of food has increased by nearly 900 percent. Besides this fact, obesity has risen by 214 percent and nearly two out of every three adults in America are overweight or obese. Being overweight is not only an appearance problem, and it also increases the risk of various diseases including diabetes, sleep disorder and cancer.

With so much nutritional knowledge easy to find, we cannot simply ignore our present obesity epidemic(流行病). We know that fruits and vegetables are rich in vitamin. Though we are overweight, many of us choose junk food over healthy food out of habits. One explanation for our strong desire for junk food is that we learn to connect junk food with positive feelings when we are young, and changing this attitude requires a huge amount of confidence and determination. Fortunately, new research published in May 2012 has shown a simple and accessible way to make healthier food choices- the one that doesn’t rely on great determination.

The research was based on two separate studies and it was carried out by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. In the first study, 60 adults between the ages of 19 and 23 were questioned about the role of food and drinks. The survey tells us that adults prefer sweetened drinks with high-calorie, salty foods, to sweetened drinks with vegetables.

In the second study, 75 children between the ages of 3 and 5 were gathered for some experiments including drinks served with vegetables. The preschooler experiments were carried out under different situations and on different days. The researchers found that the children chose to take more green vegetables when they were served with water instead of a sweetened drink.

According to Cornwell, children learn to connect high calorie, sugary drinks such as cola, with high fat foods such as French fries, from a very early age. McAlister adds that early taste development appears to play an important role in food choices later in life. Meals served at home and meals offered at restaurants, set the stage for this idea and for the preference to choose junk food over healthy food, when beginning to take sweetened drinks.

“Our taste preferences are heavily influenced by regularly eating particular food and drinking particular drink,” states Cornwell. “If the drink on the table goes against both adults and children eating their vegetables, then perhaps it is time to change that drink… and to serve water with all meals. Restaurants could easily use water as free drink for children’s meals and charge extra money for other drinks.” Both McAlister and Cornwell are confident that serving water with meals could effectively reduce the nation’s obesity rates, diabetes rates and ever rising healthcare costs.

Dye (染料) can bring a little color to life. Most clothing is colored with dyes. Modern, manufactured dyes can be costly. Natural dyes from plant and animal products have been used since ancient times. So this week, we describe a natural way to dye wool.

There are several methods to put dye onto material. The vat method, for example, can be used to dye wool with onionskins. For this example, use one hundred grams of natural wool. The wool must be clean. Leave it overnight in water and liquid soap. Then wash it with clean water that is a little warm. Gently squeeze out the extra water.

A solution called a mordant (媒染) is used in the dying process. A mordant helps fix the dye to the material. Traditionally, mordants were found in nature. Wool ash is one example. But chemical mordants such as alum are popular today. Alum is sold in many stores. It is often mixed with cream of tartar, a fine powder commonly used in cooking.

Mix eight grams of alum with seven grams of cream of tartar in a small amount of hot water. Add the solution to a metal pan of cool water. Next, add the wool and place the mixture over heat. Slowly bring the liquid to eighty-two degrees Celsius. Heat the mixture for forty-five minutes. After it cools, remove the wool and wash it.

To prepare the dye solution, cover thirty grams of onionskins with water. Use only the dry, brown outer skins. Boil the liquid until the onionskins lose their color, about forty-five minutes. Remove the skins after the dye cools.

Now it is time to dye the wool. Place the wool into the dye and heat the mixture. Bring it to a boil, then immediately reduce the heat to eighty-two degrees. Now heat the dye for about forty-five minutes or until the wool is the desired color. Keep in mind that wet wool looks darker than it is.

Once the dye cools, remove the wool and wash it. Now the wool is orange or yellow. Or at least it should be.

It all starts with a tree．In fact, it starts with several trees．Since the first modern guitars were made in northern Spain over 150 years ago, crafts persons have known the wood to be used is important in making a guitar.

Every guitar is made of several different kinds of wood．Each piece is carefully chosen and then cut to fit the part of the guitar for which it is designed．The most important part of a guitar is the soundboard--the piece of wood with a large hole that lies under the strings(弦,线)．Guitar makers are careful to make the soundboard just the right shape and thickness．Then they fix stripes（长条）of wood across the inside in a special pattern, which helps strengthen the soundboard and improves the tone of the guitar.

Wood for the curvy (弯曲的) sides of the guitar must be soaked (浸湿) in water and bent over a hot iron pipe．When all the pieces of the guitar are ready, they are carefully stuck together with glue．Special woodworking tools are used to shape and smooth the neck of the guitar．The craftsperson must make sure that the neck is perfectly centered over the soundboard.

Then it is time to use varnish(亮光漆)．This brings out the beauty of the wood．Varnish also improves the sound of the guitar but too much varnish makes the guitar sound flat and dull.

Finally guitar strings are attached and tightened to make just the right musical tones．Then it’s time to play a song．(273 words)
