Pupils remember more and behave better when 3D images are used in lessons, research suggests. They are quicker to learn and absorb new concepts, and display higher levels of concentration.
Professor Anne Bamford, of the University of the Arts, London, studied the effectiveness of 3D content in 15 schools across seven countries, including the UK. Pupils in 3D classes could remember more than those in the 2D classes after four weeks, improving test scores by an average 17 percent compared with eight percent for 2D lessons. They gave more detailed answers to the tasks and were more likely to think in 3D, using hand gestures and mime (模仿动作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding, increased attention span, more motivation and higher engagement in the lessons
Children are used to 3D with the rise of computer games that use the technology—90 percent of those in the study had seen a 3D film. Schools would need 3D-enabled projectors（投影仪）, laptops with good picture capabilities, 3D software and glasses for children to introduce animations (动作) into classrooms.
But Danny Nicholson, an educationist, said the technology would be impractical to use in schools and could be too expensive. He said,“While I think the idea of 3D technology is very interesting, I worry that 3D is a bit of an expensive gimmick (小玩意儿). There are a few cases where a true 3D image might help, but most of the time, good 2D models that can be moved , would be just so effective.”
In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms. And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils. Those who watched the 3D presentations were more engaged and reported a general increase in their interest in science compared with students who watched the 2D version.

"Sticks and stones may break my bones, but words will never hurt me."
You probably heard those lines in grammar school, but do you really agree that harsh (严厉的) or negative words do not harm us? Words have power. Surely we all have had our feelings hurt by something someone said.
We may not say words to hurt others, but the way we interpret (解释) them and how we say them may cause great harm. Here’s an example:
An ancient king dreamed all his teeth had fallen out. He sent for a wise man to explain his dream to him: the dream means that all your relatives will die and you will be left alone!
The king was very angry and threw the interpreter into prison. He then sent for another interpreter who said, "Congratulations! King! You will live many more years. In fact, you will survive all your relatives. Long Live the King!"
Both interpreters gave the same interpretation, but there was a huge difference in the way they said it.
Our speech must be understood by those who hear our words, but the way we say things and the intention behind them have as much power as the words themselves. Words can cause anger or appreciation. Which would you rather receive?
People who say harsh and negative things may not mean to harm, but have you ever known anyone who is a naysayer? They often look at the dark sides of things. They always see the glass as half empty rather than half full. How do you feel when you are around this type of person? Remember words have power. Use them wisely.

A youth went to visit a sage (智者) in a mountain 1. the wisdom of life.
“Could you please tell me what is the most important day in our lives? Is it the day we die or the day we were born, 2. the day our career takes off?” the youth asked.
“ 3. of those. The most important day in our lives is today.” The sage replied immediately.
“Is 4. because of my visit?” the youth asked in surprise.
“Even if nobody visited me today, today would still be important. No matter how memorable yesterday is, it has gone by like 5. ship sinking into the sea, no matter how brilliant tomorrow may be, it is not yet to come; but6. simple today is, it is under your control.”

As a young girl growing up in rural Alabama, I never understood why my mom spent so much time baking. And she always made my brother and me 36 her. A whole day every other week was devoted to making bread. It always made our small arms tired.
Despite our best efforts, the flour dust always went everywhere. I 37 to be outside with my playmates, and never 38 my mom’s desire for quality family time with her children, at least when it came to spending it in the 39 . Years have gone by, and I have become a mother myself. I prefer to leave most of the cooking to my husband and he loves it. He’s quite 40 at doing it, too.
On one occasion my husband was 41 dinner, and I was at the kitchen table going through the day’s mail when our little son, Cody, asked if he could help 42 . My husband said yes, and I sat there amused, watching them.
“What are you doing?” I asked.
“Helping dad cook.” he replied with a big 43 on his face. I thought back to those 44 when my mom asked me to help her bake bread, and I was 45 , but obeyed. Perhaps she was trying to create something more than just fresh bread—maybe a few lasting 46 .
As I watched Cody do it with all his attention, I realized that he had 47 a lasting moment for me, a moment filled with a deep sense of family. I wanted to hold the moment and make it longer, and appreciate the memories my mom had given me years ago in her kitchen.
