In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.

    In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them.

    "Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium (铊) poisoning(中毒)."

    "What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."

    "A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's."

    "You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."

    Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance(物质) used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar.

    Since 2013,Torobo, a robotic are designed to test the limits of artificial intelligence, has had one ambition—to be admitted to the University of Tokyo, one of Asia's top-ranked educational institutions. Although equipped with an extensive database of textbooks and other teaching materials, Torobo has repeatedly failed to obtain the university's required minimum 80% score in the National Center Test, a yearly standardized entrance examination adopted by Japanese universities. This year was no exception.

    In early November, Torobo, along with millions of Japanese high school students, took a mock(模拟的)exam to prepare for the all-important standardized test.

    Torobo's total score of 525 out of 950, which was higher than the national average, was enough for it to get admitted to many other influential Japanese universities.

    However, its standard score of 57.1%, though 14 points higher than in 2015, still fell short of the minimum required for the University of Tokyo.

    A closer analysis of the results showed that Torobo was able to draw from its database to solve knowledge-based questions and ones involving complex mathematical calculations, but it had a hard time thinking independently, failing to comprehend multiple sentences and phrases to arrive at the logical conclusions. This weakness was reflected in its shabby English scores.

    Fortunately, the robot's creators have decided to free Torobo from its four-year sufferings. Noriko Arai, professor of the University of Tokyo who heads the team, says, “From the present results, we are able to evaluate the possibilities and limits of artificial intelligence. From now on, we will grow its abilities in the fields where it is doing well and aim to improve them to levels that can be applied in industry.” So while Torobo will never graduate from the University of Tokyo, it can still look forward to a bright future!

    Do you often feel that you aren't taking in as much of the joy around you as you could? I recently caught myself feeling this way, and based on a suggestion by John Horton, coauthor (合著者) of The Inner Game of Stress, I put myself on a 30-day life-appreciation course.

    The only assignment each day was to go outside and appreciate life.

    So I started by taking in the beauty around me. During the first few days, I was able to appreciate my surroundings, although it was an intellectual appreciation, not an emotional one.

    After the first week, it was more uncomfortable to lie in bed and think about things than it was to get up and see them for myself.

    If you often wake up feeling anxious or depressed, or if you don't look forward to each day, then you need to try this course for yourself.

    It's an inner workout that you can do anywhere. It may not change your life, but it will adjust your attitude, and that's pretty helpful in this crazy world.

    I have always believed in ending the day on a positive note by writing a word or two in a gratitude journal and saying something sweet to my wife about the day we shared.

    Now, I have a new morning habit. It hasn't changed my routine one bit, but it has changed the way I look at the world.

    Creating a new habit isn't about perfection – it's about getting what you want by creating a change in your behavior and thinking.

    So now, while I'm making my coffee in the morning, I'm also appreciating what I have.

    It's quick, fulfilling, and a much better way to start my day than looking at my phone or computer.

    And because of this, my attitude is better, as I've already begun my morning on a positive note rather than a problematic one.

    The idea here is that if you can appreciate your life, it actually changes the way you feel about it.

    Appreciation will give you more energy to live the way you would like to live.

    As a means of improving our mood, it's highly underrated (被低估的). The easy task of appreciating what we have simply makes life better.

London Underground

    The world's first subway was built in London in 1863. At the time, the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work, they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems, the idea of the London Underground, the first subway system, was born.

    The plans for building the Underground met with several problems and delays, but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30,000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed), and pleasant decorations inside each of the cars. However, the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰), as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems, riding in the Underground did catch on. It carried 9 million riders in its first year.

    A traveller was staying in an Egyptian village. One day, she held up her camera to take pictures of the children. Suddenly the young ones began to shout at her. The traveller's face turned red and she apologized to the head for what she was doing, and told him she had forgotten that people in some places believed a person would lose his soul(灵魂) if his picture was taken. She explained to him the operation of a camera for a long time. Several times the head tried to say something, but he couldn't. When she believed that the head didn't fear any longer, the traveller then let him speak. With a smile, he said, "The children were trying to tell you that you forgot to take off the lens(镜头) cap!"

I stood outside my front door catching my breath. After a lazy Christmas holiday, I had to recover from climbing stairs with carry-on bags and a suitcase. I looked up — Red tape crossed the door. I didn't understand French, but the one English word said enough, "POLICE". Google Translate told me I would be caught if I entered, so I didn't.

Finally, I called my rental agent (收租人). He went to the police station for more details. The thief had taken a few items from the top drawer as well as a small amount of money in the bottom drawer. Not only were my files undisturbed, but so were the TV and printer. My agent also said something about fixing the locks tomorrow and making a list for the police.

Then one day, I remembered that I had left another jewelry box in the flat. My heart sank as I thought of a gold locket (项链坠) with a picture of my late Grandma inside. When I realized the box was missing, the whole experience seemed to crash down on me. I cried. At the end of January, I received a letter from the police. The thief hadn't been found, and the case was closed. I slept with my purse by my bed. I hid my laptop when I showered. And then another challenge came — I was unexpectedly fired by my company.

One July night, I reached into my third drawer to pull out my jean shorts. I heard something fall to the ground. I looked down: It was the tiny jewelry box I thought had been stolen six months earlier. Inside was the locket with honey Grandma smiling at me, being there for me, telling me not to give up. I started to cry. I knew that things were going to be OK.
