Think about what you had for lunch: Was it a hamburger? A chicken sandwich? Barbecue? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet?
It can—in a big way. New studies show how food and its production affect the globe and its warming climate. You’ve probably heard of global warming : The temperature is on the rise because humankind has been releasing (排放) amounts of gases into the atmosphere. One of these greenhouse gases is carbon dioxide（二氧化碳）.
What does this have to do with food ? A big part of the carbon dioxide that we put in the atmosphere every year comes from the process of making and eating food. The production of meat contributes a lot of that carbon diode. And much of meat’s contribution comes from beef , which is responsible for releasing even more warming gases into the atmosphere.
The process of making a hamburger ,for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow waste is a major source of methane (沼气) — an especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed (加工) and shipped to a shop, which takes fuel . Most of the cow won’t even be used for meat that people eat. By the time a hamburger finally lands on a dinner plate, it has made a heavy effect on the environment.
We can reduce the production of global-warming gases by eating less beef .Other kinds of meat like pork and chicken do less harm to the environment—at least in terms of the amount of greenhouse gases released.
All kinds of meat are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide into the air. So changing our diet to less meat and more vegetables, as it turns out, may do the world some good.

As a music teacher for twenty-seven years, I have always known that music touches the soul. It can break through all kinds of barriers(障碍) to reach students in a very special way. It can be the means for each child to find their light.
A few years ago, I was blessed with the opportunity to teach pre-school students one afternoon a week. One of my most memorable students was Vanessa. She was five years old, had difficulty walking, and could not speak. We mostly sat on the floor for our music lessons and Vanessa liked to sit on my lap. One of her favorite songs was John the Rabbit. It was a call and response song where I sang the call and the students clapped two times while singing the repeating phrase, “Oh, yes!” Vanessa liked to put her hands together with mine and clap with me. We performed that song during every class, Vanessa and I clapping together. She never said or sang a word.
One day late in the school year, when the song was finished, Vanessa turned around, looked me in the eye, clapped her tiny hands two times and said the words “Oh, yes!” I opened my mouth and could not speak. Through music, we had made a connection.
Several years later, I came across Vanessa on the street in town. I stopped my car and waved to say hello. She waved back with a big smile on her face and then clapped her hands two times, mimicking(模仿) the song we had performed in our music class. This precious little girl, through her connection with music, left an impression on me that will last forever.
Every child has the ability to learn and grow. It is up to us educators to discover the way to reach each and every one of our students. We all must find each child’s light.

Have you ever been to a wedding and simply loved the bride’s bouquet（花束）？More than likely some part of it was the Hawaiian Wedding Plant. This foreign houseplant can be enjoyed by anyone, not just brides. With a little proper attention and careful planning on location, this foreign houseplant, which is from Madagascar, can be brought into the home where it can become an interesting focus.
Caring for the Hawaiian Wedding Plant is not much different from caring for any other houseplants that may already be in your home. The only difference between this type of houseplant and others is the amount of the basic requirements that this foreign houseplant needs to survive and perform beautifully. During the growing season, this plant requires its wet soil, but when winter rolls around, this plant needs its soil to be kept drier.
Hawaiian Wedding Plants should also be potted in well-drained(排水)soil and placed in a location that receives full sun. That the soil must be kept wet does not mean that it should sit in water, so the soil must drain easily or this plant will not survive. Water the plant daily and feed this plant every two to three weeks with a little fertilizer(化肥) for acid-loving plants. Prune in early spring, even as early as February. If these needs are met, this plant will stay beautiful.
The most special feature of this foreign houseplant is its long lasting blooms(开花)combined with its unbelievable sweet smell. The Hawaiian Wedding Plant blooms the heaviest in the spring months, but has been known to bloom in any warm months, so do not be surprised to find blooms most time of the year except maybe in the dead of winter.

At the end of eight grade, our class went to Washington, D.C. For a group of 14-year-olds, this was a big deal!
The first day was so tiring; we could hardly remember where we were and what we were seeing. The next morning, we were off to see monuments (纪念碑)，starting with Washington, Lincoln and Jefferson. We walked along the paths through trees. Then the Wall came into view—the Vietnam Veterans Memorial.
As I moved slowly closer to the Wall, I heard a bagpipe（风笛）in the distance, which seemed to show respect to the lives lost in the jungles of Vietnam .
We continued walking and felt surprised at the number of names carved in the black stone. I was determined to find a soldier with my last name, but my hunt was stopped when a man caught my eyes. He was kneeling(跪着) at the Wall, a single rose at his feet. His head was bowed and he was rubbing his fingers over one name. I thought how sad he was, and then moved on .
After a few minutes I found one with my last name, but my eyes returned to the kneeling man. He was still rubbing his fingers over the same name. He never knew I was watching him, lost in deep sorrow. It was time for me to leave the kneeling man and the Wall. On the way home, I couldn’t help thinking of the kneeling man and his sad face. I wasn’t sure of the effects of war before, but at that moment I realized how much that man suffered from losing his loved one. Maybe he was the only one of so many families who experienced the same .
I never knew the full effects of war until I saw that man. I only know about war from history classes. The kneeling man taught me more about war and the effects it has on people than any history book .
