With the popularity of 3D movies over the past several years , there was no doubt that the technology would make its way into our homes, The question is: Is it really a technology that is going to stay with us , thus deserving an upgrade(升级) at this time?
Many families have recently bought a new TV set, and the idea of changing it just to take advantage of a technology in its infancy(初期)will put many people off the idea. Then there are the additional costs that come along with a 3Dset from needing to get a Blu-ray player that can process the signal to purchasing enough glasses for the entire family to be able to watch a program at the same time.
Another issue is that the glasses are expensive as well as complicated, and have also been known to cause headaches, none of which makes for a pleasant experience.
While manufacturers are working towards glasses-free technology, it just isn’t here yet, and it could be several years before it is commercially successful. That is one of main things that will keep 3D completely in the “fashion” zone for the time being . If the television manufacturers are willing to hold onto the idea until glasses-free choices are available—and they can reach a higher installed(安装)user base—this might very well catch on. Everyone needs to remember, however, that these are businesses, and they are in it to make money. If 3D isn’t selling at the rate they are comfortable with, then they will dump it and move on to the next thing.
Many homes are filled with products that didn’t catch on rapidly and companies ended up leaving them with no support. Do you have an HD DVD player? Remember how the MiniDisc was supposed to replace the CD? For now, it’s easy to see how 3D televisions could join this list of technologies.
There is one upside to the 3D television problem: They have beautiful 2D images. Even if 3D goes away, you still have a great –looking screen and beautiful images. If you are in the market for a new TV and you can afford to drop the couple extra hundred dollars to buy one, you can view it as guaranteeing your purchase in case the technology proves to be effective.

Emilio and Michi spread the colorful tablecloth on the table. They made room for Drew, who was carrying a dish. “Watch out,” Drew warned. “This is pretty hot.”
A moment later, Kent and Alyssa added another hot dish to the table. “That smells so good!” said Michi. “Are most of the parents here yet? I’m hungry.”
Kent looked through the doors that led into the hallway. “I think Ms. Milano and Mr. Hasselbach just finished giving them the garden touring. They should be heading into the cafeteria next.”
The students of Jefferson Middle School in Saint Louis, US had spent all afternoon preparing for the evening meal. They did their best to transform the lunchroom into a beautiful dining area for their families.
As the families found their seats, Ms. Milano asked Drew, Emilio, and Michi to join her at the front of the room. She said, “I just wanted to take a moment to congratulate Drew, Emilio and Michi for their wonderful idea. A year ago, they first came to me with the plan for starting a garden at Jefferson. I wondered whether it would work, but they had thought through everything. Any time I had a question about how we would make this work, they had an answer prepared. As you can see, they were absolutely correct. About three-quarters of the food you will be enjoying came from the school garden. The students prepared the entire meal themselves.”
Ms. Milano handed Drew, Michi and Emilio a box each. They opened their box as Ms. Milano continued. “As a thank-you to these students for their creative idea and hard work, they have each received a stepping stone(垫脚石)for the garden. Their names and date appear on the stones.”
She turned to them. “Students for years to come will be enjoying the garden that you helped create,” she said. “We thought it would be appropriate for them to have a reminder of our garden’s founders.”

Watercress is positively packed with healthy vitamins and minerals. The writings of both the Romans and the Ancient Greeks record the consumption of watercress by all classes. Hippocrates, “the father of medicine”, was so convinced that watercress was a great healer that he built his first hospital next to a stream so that he could grow a plentiful supply of the shiny green leaves for his patients. The Romans chewed watercress in large quantities, believing that it would cure baldness. They, too, looked with favor on watercress as a salad.
Watercress sandwiches were traditionally a breakfast item in nineteenth-century Europe. The most basic type of watercress sandwich has two pieces of white bread with a mixture of butter and watercress greens . A nickname(绰号)for the vegetable, in fact, was “poor man’s bread”, because watercress was often eaten on its own for breakfast by families that could not afford the bread to go with it.
Watercress is a member of the mustard(芥菜) family. It contains vitamins C(66mg per 100g), K and A, and is also a valuable source of minerals such as iron, potassium, copper and calcium. The mustard oils in its silky leaves and stems(茎)contain an ingredient known as PEITC. Recent research has proved that PEITC can prevent the growth of cancer cells and, in some cases, actually destroy them.
The best watercress has silky green leaves without any marks and has undamaged stems, The older the plant, the darker are its leaves and the thicker its stems. This means a higher concentration of oils and vitamins. Young watercress, on the other hand, may be harvested after only twenty-eight days growth and has a milder taste. It is best to eat watercress fresh and raw , to keep more of its valuable nutrients, but it can be lightly cooked and used as an alternative to spinach—another dark green vegetable—in various recipes. From soups to salads, watercress is now considered around the world as a natural and healthy super food.

When I was about 6 years old I lived in Kenya. There was a lot of and there were always street children on the roads asking for money. There was such a big divide between those children and me and I grew up very aware of being so .
We had a wonderful and very kind driver, John, who had been working with my for decades. He used to take us to and from school. One day while we were stopped in traffic a young street child, probably no more than 10 years old, with a friendly greeting, “Hi, John!”
He the car and shook John’s hand,. John then gave him a little bit of money and waved him off with a smile before we carried on our way to school.
I had watched the whole incident completely . John had a large family himself and had to work very hard to make ends .I knew that he didn’t have any spare money. So, of course, at that age I couldn’t understand why he would be giving money to the child.
“Who was that?” I asked. “My friend,” he replied. “I see him every morning on my way to work and I give him a little bit of money.” Unable to comprehend, I asked, “Why do you have to give him money every morning?” John replied, “So he can use it to buy some food.”
It was probably at that that I understood what kindness really was. A person who was in a difficult situation himself still found some money to for a child who needed it. Even at the age of 6 that had such a great impact on me. I didn’t have any money, but I wanted to too. So when my grandfather gave us a chocolate bar after dinner every Friday, I would mine up so I could give it to John to give to his friend.
