LONDON—Terror struck in the heart of London on Thursday as explosions ripped through three subway trains and blasted(炸开)the roof off a crowded red double-decker bus. At least 37 people were killed and more than 700 wounded in the deadliest attack on the city since the blitz(闪电战)in World War II.

British Prime Minister Tony Blair blamed Islamic extremists and said the bombings were designed to coincide with the opening in Scotland of a G-8 summit of the world's most powerful leaders. Foreign Secretary Jack Straw said the bombings—which came the day after London won the bid to host the 2012 Olympics— have the “hallmarks(特点)of an al-Qaida-related attack”.

    Trapped passengers in the Underground railway threw themselves on the floor, some sobbing. As subway cars quickly filled with smoke, people used their umbrellas try to break the windows so that they could get air. Passengers emerged from the Underground covered with blood and soot(黑烟). On the street, in a light rain, buses ferried the wounded, and doctors used a hotel as a hospital.

     “I didn't hear anything, just a flash of light, people screaming, no thoughts of what it was. I just had to get out of the train,” said subway passenger Chris Randall, 28, who was hospitalized with cuts and burns to the face, the legs and hands.

     “It was chaos(混乱),” said Gary Lewis, 32, evacuated(撤离)from a subway train at King's Cross station. “The one haunting(萦绕)image was someone whose face was totally black( with soot) and pouring with blood.”

    Police said there had been no warning and that the blasts at three subway stations went off within 26 minutes, starting at 8:51 a.m. in an Underground train just outside the financial district. Authorities initially blames a power failure but realized it was a terror attack after the bus bombing near the British Museum at 9:47 a.m.—less than an hour after the first explosion.

    It was a quiet village in which there was a military camp(军营). It was far from the towns and cities and there were some high mountains around. Of course it was a good place for training the new soldiers. But it was difficult for the young men to go outside. Mr. White, an officer of forty, was strict with them and he hardly let them leave the camp.

    Once Mr. White was ill in bed. He couldn't work and a young officer, Mr. Hunt, began to train the new soldiers instead of him. He knew the young men well and let nine soldiers go to the nearest town to have a holiday. But night fell and none came back to the camp. He was worried about it and stood at the gate. It was five to twelve when Mr. Hunt decided to go to the town and see what was happening with the young men. He started the car quickly and set off. At that moment the nine soldiers came back. It seemed they were all drunk. Of course they found the officer was angry.

    "I'm sorry, sir," said the first soldier. "I left the town on time. But something was wrong with my bus on my way here. I had to buy a horse and made it run fast. Bad luck! It died and I had to run back."

    And the other seven soldiers said they were late for the same reasons. It was the last soldier's turn. He said, "I'm sorry, sir. I got on a bus on time, but…"

    Having heard this, the officer became even angrier and stopped him at once. He called out, "If you say something was wrong with your bus, I'll punish you at once!"

    "No, no, sir," said the young man. "My bus was all right, but the dead horse were in its way!"

    Adults understand what it feels like to be flooded with objects(物品). Why do we often think that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.

    I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund (基金) (our kindergarten daughter is serious about becoming a doctor).

    For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball — simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.

    We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.

    A 27-year-old inventor, Joco Paulo Lammoglia, has come up with a new device ( 设 备 ) named the AIRE mask, which is capable of transforming the wind energy provided by the wearer's breath into electrical energy. This means breathing has become a source of renewable energy. The inspiration for the invention came from his watching children blowing on pinwheels (纸风车).

    The device is worn like a mask equipped with tiny wind turbines (涡轮) and it can work its magic even while people are sleeping, running or hanging around, since energy is created from one's breath. The principle of this AIRE mask is simple. The invention uses the wind flow created by breathing and changes it into energy that can charge mobile phones and iPods. Simply put this mask connected to your mobile phone on your face. The rest takes place naturally through your breath that provides power to run turbines which produce electricity.

    Lammoglia explained how useful he hopes the AIRE will become. He said, "I hope to bring the concept into production and reduce the carbon footprint. It can be used indoors or outdoors, while you're sleeping, walking, running or even reading books." Apart from saving energy and contributing to environmental protection, it also encourages the practice of physical exercise. This is an entirely all time renewable energy source. Its energy is available 24 hours a day, seven days a week.

    Lammoglia explained why he thought the AIRE was so useful, saying, "Though many of our modern devices offer benefits, they tend to consume a high amount of electrical energy. This may cause problems for the environment, especially if the energy used by these devices is produced by non-renewable sources.

    The AIRE mask will be future's cheaper source of charging mobile phones. It would save energy and allow people to never have to worry about their phone dying unless they stop breathing.
