I know what you're thinking: pizza? For breakfast? But the truth is that you can have last night's leftovers in the a. m. if you want to.
I know lots of women who skip breakfast, and they have a ton of different excuses for doing it. Some say they don't have time, others think they're “saving” calories, still others just don't like breakfast food.
But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R, D, who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it's loaded with vegetables, and you stick to one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it... you may save yourself some pre­bedtime calories. And watch your body gain the fat­burning effects.

The writer Margaret Mitchell is best known for writing Gone with the Wind, first published in 1936. Her book and the movie based on it, tell a story of love and survival during the American Civil War. Visitors to the Margaret Mitchell House in Atlanta, Georgia, can go where she lived when she started composing the story and learn more about her life.
Our first stop at the Margaret Mitchell House is an exhibit area telling about the writer’s life. She was born in Atlanta in 1900. She started writing stories when she was a child. She started working as a reporter for the Atlanta Journal newspaper in 1922. One photograph of Ms. Mitchell, called Peggy, shows her talking to a group of young college boys. She was only about one and a half meters tall. The young men tower over her, but she seems very happy and sure of herself. The tour guide explains: “Now in this picture Peggy is interviewing some boys from Georgia Tech, asking them such questions as ‘Would you really marry a woman who works?’ And today it’d be ‘Would you marry one who doesn’t?’ ”
The Margaret Mitchell House is a building that once contained several apartments. Now we enter the first floor apartment where Ms. Mitchell lived with her husband, John Marsh. They made fun of the small apartment by calling it “The Dump ” .
Around 1926, Margaret Mitchell had stopped working as a reporter and was at home healing after an injury. Her husband brought her books to read from the library. She read so many books that he bought her a typewriter and said it was time for her to write her own book. Our guide says Gone with the Wind became a huge success. Margaret Mitchell received the Pulitzer Prize for the book. In 1939 the film version was released. It won ten Academy Awards, including Best Picture.

When I was a kid, I used to spend hours listening to Adam Carolla and Dr. Drew Pinsky on their Sunday night radio show Loveline. I listened so often that I began to use one of their well-known phrases—“good times”—in my daily conversations. Scientists have a name for this phenomenon: behavioral mimicry.
You’ve probably experienced this before: after spending enough time with another person, you might start to pick up on his or her behavior or speech habits. You might even start to develop your friend’s habits without realizing it. There is a large body of literature concerning this sort of phenomenon, and it regularly happens for everything from body postures to accents to drink patterns. For example, one study found that young adults were more likely to drink their drink directly after their same-sex drinking partners, than for the two individuals to drink at their own paces.
And the effect isn’t limited to real-life face-to-face activities. Another study found that the same you-drink-then-I-drink pattern held even when watching a movie! In other words, people were more likely to take a drink of their drinks in a theater after watching the actors on the screen enjoy a drink. At least I don’t feel so strange anymore, having picked up on Adam Carolla’s “good times”.
New research published today in the journal PLOS ONE indicates that the same sort of behavioral mimicry is responsible for social eating, at least among university-age women of normal weight. That’s right: the young women were more likely to adjust their eating according to the eating pace of their same-sex dining companion.
As with most experiments, these results raise a whole new set of questions. Still, the finding that behavioral mimicry may at least partly account for eating behavior is important, and has real effects on health. The researchers note that “as long as people don’t fully recognize such important influences on intake, it will be difficult to make healthy food choices and keep a healthy diet, especially when people are exposed to the eating behavior of others”.

As a senior, my future is always on my mind. To be exact, thoughts of the future have kept me up countless nights and made me worry enough to do poorly on more than one test. Because of this, words of wisdom are a source of comfort. Steve Jobs gave a speech to Stanford’s graduating class in 2005 and his words resound repeatedly in my mind whenever I think about my future.
It wasn’t always like that, though. It started when I became a junior, when college came into view. It’s the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He, too, felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well.
This doesn’t mean that students shouldn’t attend college, but rather that they shouldn’t worry so much. You’ll get where you need to go, even if your path is a bit more winding（蜿蜒的）than you’d like.
Jobs talked about the hardships in his work. His love of his work helped him carry on and he got where he was meant to be, which restates the point: don’t panic.
One particular part of his speech stayed with me. Steve Jobs quoted（引用）the saying “Stay hungry, stay foolish” and it has become my motto. Staying foolish is realizing that you are still a fool, no matter how much you’ve learned or experienced. There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated.
Steve Jobs’s level of success is attainable, and I aim to prove that. With the will power to go into the world living every day like it’s my last and allowing the future to take care of itself, I will do great things. In the last moments of my life, I’ll be proud of what I have done and hope to have all the wisdom a person could wish for.

When you put down your pens at the end of the college entrance exam, 12 hard years of study will have come to an end. Forget your studies for a while. It’s time to enjoy yourselves!
There are many ways to celebrate this special month of graduation. You can have photos taken with your classmates and teachers, or dine out together and exchange gifts.
High school students in western countries such as the United States and Canada usually have party to mark their graduation. It’s to mark the time when kids turn into young men and women. After the party, teenagers either go to college or find a job. It means they will no longer depend on their parents as before.
As the party, boys usually dress in dinner jackets and bow ties, though many different types of formal clothes are worn. Girls traditionally wear formal dresses, or dress to shock or be noticed, in shiny or brightly colored materials.
Common party activities include dining, dancing, the crowing(加冕)of a ball king and queen, and just talking to friends. In some cases, high school students collect funds for their class party through the four years of their high school.
High schools in or near large cities may rent big rooms at expensive hotels or，to be unusual, on a pleasure boat.But often costs are out by simply using the school gym.Students make a lot of effort to decorate the gym to make the event special.The music played at the party will be the most popular kinds，like rock and hip-hop.

At 2 p.m. on December 5, 1945, five Navy aircraft took off in perfect flying weather from a naval air installation in southeastern Florida, on a routine training mission over the Atlantic Ocean. Less than two hours later, the flight commander radioed that he was “completely lost”. Then there was silence. A rescue plane was sent to search for the missing aircraft, and it, too, disappeared. Despite one of history’s most extensive search efforts, involving more than 300 planes and dozens of ships, the Navy found nothing, not even an oil stain floating on the water.
This is just one of the many frightening stories told of “the Bermuda Triangle”, a mysterious area of the Atlantic Ocean roughly stretching southwest from Bermuda to the Florida coast and down to Puerto Rico. During the past 30 years, the triangle has claimed the lives of some 1,000 sailors and pilots.
Stranger yet are the numerous “ghost” ships that have been found floating crewless within the triangle. On one strange occasion in 1881, the cargo ship Ellen Austin discovered a small sailing ship, sails waving uselessly in the wind. The boat was full of wood with no one on deck. The captain of the Ellen Austin installed a new crew to sail it, but two days later, during a rough storm, the two ships temporarily lost sight of each other. When the captain again boarded the boat, he found his crew had disappeared. After a second crew was assigned, the ship was again lost in a fog bank. This time, no trace of the boat — or the crew — was ever found.
Charles Berlitz, a man with an interest in Atlantis, the legendary lost island, puts forward his theory that a giant solar crystal, which once was the power generator for Atlantis, lies on the ocean floor. From time to time, according to his theory, passing ships and planes set off the crystal, which confuses their instruments and engulfs them into the ocean.
Officially, the U.S. Navy does not recognize the triangle as a danger zone and is convinced that “the majority of disappearances in the triangle can be due to the unique features of the area’s environment.” These include the swift Gulf Stream current and the unexplored valleys under water of the Atlantic. Also, the triangle is one of only two places on earth where a compass needle points to true north rather than magnetic north, causing problems in navigation.
However, other scientists argue that beings from outer space have established a highly advanced civilization in the unexplored depths of the Atlantic inside the triangle. There, they believe, most of the missing vessels – and their crews – may still be on display for study by these higher intelligences.

For the 17 years my life was very happy. Then the first sad thing happened. My mother became very ill, and soon she knew that she was dying. Just before she died, she asked Elizabeth and me to go to her room. She held our hands and said, “Victor and Elizabeth, my children, I’m very happy because you love each other, and because one day you’ll get married. Everyone in the family loves you, Elizabeth. Will you take my place in the family, my dear? I can die happy if you look after them when I have gone.”
My mother died and we were very sad, because we loved her dearly. Elizabeth was brave and helped us; her sweet smile gave us some happiness in the unhappy days after my mother’s death. The time came for me to go to university. I didn’t want to leave my sad family, but we all knew that I should go. It was hard to leave, too, because the parents of my good friend Henry would not let him go to university with me. So I had gone alone.
On my first day at university I met my teacher, Professor Waldman, who was one of the greatest scientists in the world. He gave a wonderful talk to all the students who were starting at the university. He ended his talk by saying, “Some of you will become the greatest scientists of tomorrow. You must study hard and discover everything that you can. This is why God made you intelligent—to help other people.”
After the professor’s talk, I thought very carefully. I remembered the storm when I was 15; I remembered how the lightning had destroyed the tree. From then on, I wanted to use electricity to help people, and I wanted to discover the secrets of life. I decided to work on these two things.
I started to work the next day. I worked very hard and soon Professor Waldman and I realized that I could learn to be a very good scientist.
The professor helped me very much, and other important scientists who were his friends helped me, too. I was interested in my work and I did not take one day’s holiday during the next two years, I did not go home, and my letters to my family were very short.
After two years, I had discovered many things and I built a scientific machine that was the best in the university. My machine would help me answer the most important question of all. How does life begin? Is it possible to put life into dead things? To answer these questions about life I had to learn first about death. I had to watch bodies from the moment when they died and the warm life left them. In the hospital and in the university, I watched the dying and the dead. Day after day, month after month, I followed death, so it was a dark and terrible time.
I built a tall mast about 150 meters high, which is higher than the tallest building in the city, to catch lightning and send the electricity down to my machine in the lab. I believed I could use that electricity to give life to things that were dead.
Then one day, the answer came to me. Suddenly I was sure that I knew the secret of life.

We were both in great anger.“Never set foot in this house again!” stormed Father.With tears welling up in my eyes, I rushed out of the flat and ran along the street.
The street lights were shining rather desolately(凄凉的).I wandered aimlessly.
A young father who held a child in his arms walked past me.I felt as if I saw my childhood from another space: happy and harmonious.
But now… I don’t know whether it is because I have grown up or because dad is getting old.We differ in our ways of thinking.He always imposes his opinions and codes of behavior on me.Whenever I do something wrong, he never admits it.We are just like two people coming from two different worlds.It feels like there is an iron door between us that can never be opened.
I wandered the streets, without a destination in mind.My heart was frozen on this hot summer night.As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company.When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.
In fact, it was nothing.Perhaps, dad was throwing away some of his old stamps.Perhaps he thought they were useless.I never had the courage to tell him that I liked collecting stamps.I can’t stand his outrageous(蛮横的) words: “ I can throw you away, let alone these old papers.”
All the lights were off except father’s.
Dad was always like this.Maybe he didn’t know how to express himself.After shouting at me, he never showed any mercy or any moments of regret.After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers.
This was how he always was.He has been a leader for so long that telling everyone else what to do has become his second nature.
The light was still on.“Am I wrong?” I whispered, maybe… With the key in hand, I was as nervous as I had ever been.At last, I decided to open the door.As soon as I opened the door, tears ran down my cheeks.I suddenly realized that the iron door that I had imagined between us did not exist at all.Love is second to none.

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
Fifty years ago, nature study was not part of school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.
For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table (水位) in ground is just as important to us as a knowledge of the basic math formulas(公式). We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic（立方体的） volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can
