Suddenly another thought went through Kate's mind like an electric shock. An express train was due to go past about thirty minutes later. If it were not stopped, that long train, full of passengers, would fall into the stream. “Someone must go to the station and warn the station-master，” Kate thought. But who was to go? She would have to go herself. There was no one else.

    In wind and rain she started on her difficult way. Soon she was at the bridge that crossed the Des Moines River, a bridge also built of wood, just like the bridge across Honey Creek. The storm had not washed this away, but there was no footpath across it. She would have to cross it by stepping from sleeper (枕木)to sleeper. With great care she began the dangerous crossing, sometimes on her hands and knees, hardly daring to look down between the sleepers into the wild flood waters below. If she should slip, she would fall between the sleepers, into the rapidly flowing stream.

At last -- she never knew how long it had taken her一 she felt solid ground under her feet. But there was no time to rest. She still had to run more than half a mile and had only a few minutes left. Unless she reached the station before the express did, many, many lives would be lost.

    She did reach the station just as the train came into sight. Fortunately the station-master was standing outside. “The bridge is down! Stop the train! Oh, please stop it!” Kate shouted breathlessly.

    The station-master went pale. He rushed into the station building and came back with a signal light. He waved the red light as the train came into the station. It was not a second too early.

    Could the device, smartphone or PC, which you are using affect the moral decisions you make when using it? To test it, researchers presented multiple dilemmas to a sample set of 1,010 people. The participants were assigned a device at random.

    One case of the questions participants were asked is the classic “trolley(有轨电车) problem”: A runaway trolley is headed towards five people tied up on a-set of train tracks. You can do nothing, resulting in the deaths of five people, or push a man off a bridge, which will stop the trolley. The practical response is to kill one man to save five lives, which 33. 5 percent of smartphone users chose, compared to 22.3 percent of PC users.

    “What we round in our study is that when people used a smartphone to view classic moral problems, they were more likely to make more unemotional, reasonable decisions when presented with a highly emotional dilemma, “Dr Albert Barque-Duran, the lead author of the study, told City, University of London. “This could be due to the increased time pressure often present with smartphones and also the increased psychological distance which can occur when we use such devices compared to PCs.”

    As for why the researchers started this study, Dr Barque-Duran noted, “Due to the fact that our social lives, work and even shopping take place online, it is important to think about how the contexts where we typically face moral decisions and are asked to engage in moral behavior have changed, and the impact this could have on the hundreds of millions of people who use such devices daily. “It's clear that we need more research on how our devices affect our moral decision making because we're using screens at an ever increasing rate.

    The Intelligent Transport team at Newcastle University have turned an electric car into a mobile laboratory named “DriveLAB” in order to understand the challenges faced by older drivers and to discover where the key stress points are.

    Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to them becoming more isolated(隔绝) and inactive.

    Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life.

    These include custom-made navigation(导航) tools, night vision systems and intelligent speed adaptations. Phil Blythe explains: “For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.”

    “But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to.”

    Dr Amy Guo, the leading researcher on the older driver study, explains, “The DriveLAB is helping us to understand what the key points and difficulties are for older drivers and how we might use technology to address these problems.

    “For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We're looking at the benefits of systems which control their speed as a way of preventing that.

    “We hope that our work will help with technological solutions(解决方案) to ensure that older drivers stay safer behind the wheel.”

    Starting Cycling

    We have two services designed to give people the confidence and knowledge to cycle successfully.

    Lessons

    All our instructors have been trained to National Standards level of “Bike-ability”. This means you will be trained to a standard consistent across the whole country.

    There are 3 levels of skills to progress through. Children would start with levels 1 & 2, progressing from the playground or park to cycle on less busy local roads. Teenager and adult beginners can also learn levels 1 & 2 in an off-road and quiet environment.

    Confident teenagers and adults can broaden their skills by learning level 3, using multi-lane roads and larger roundabouts. We provide both a complete package of lessons for the beginner or individual lessons tailored to the client. Whatever the need we can address and practice until perfect!

    Cost is ￡30 per hour.

    Guided Ride

    We know that riding on the roads in London can be scary, and if you have to navigate (确定行车路线) as well it can become a real hard task! The Guided Ride service takes all the stress out of it for you by providing the following:

    Route planned in advance to suit your skill level. Route map provided to you.

    Cycle and equipment checked. We will teach you a simple method to check basic roadworthiness (车辆性能) of your bike that you can perform on a weekly basis.

    Route discussed and focus given to any areas requiring special attention.

    Palaces are known for their beauty and splendor, but they offer little protection against attacks. It is easy to defend a large building, but usually these buildings are not designed with the comfort of a king in mind. When it comes to structures that are both beautiful and defensive, the European castle is a big success.

    Castles were originally built in England by the Normans in 1066. They built towers and walls to secure the land they had taken. These castles provided the Normans with a quiet and safe place. They also served as bases of operation for attacks. In this way castles served both defensive and offensive roles. Besides, castles served as offices for governors. Those that were socially beneath the governor would come to report affairs and express their respect. They would address problems, handle business, feast, and enjoy festivities in castles. So castles served as social centers as well.

    The first castles were made from earth and wood, and they were likely to suffer from attacks by fire. Then wooden castles were gradually replaced by stone, which greatly increased the strength of these towers and walls. However, attackers could throw flaming objects into castles through the windows or burn the wooden doors. This led to moving the windows and entrances off of the ground floor and up to the first floor to make them more difficult to access.

    During the Middle Ages, attacks increased in regularity, so castle defenses were updated. Arrow-slits were added. They were small holes in the castle, which allowed defenders to fire without being hurt. Towers were built from which defenders could provide fire on both sides. The towers were connected to the castle by wooden bridges, so that if one tower fell, the rest of the castle was still easy to defend. A lot of rings of castle walls were constructed, so that even if attackers went past one wall, they would be caught on a killing ground between inner and outer walls. All of these increased the defense of castles.

    The end of castles can be attributed to gunpowder. During the 15th century, artillery, a kind of large guns, became powerful enough to break through stone walls. This greatly made the role of castles less effective. Though castles no longer serve their original purposes, remaining castles receive millions of visitors each year who wish to experience the situations of ancient times.

    Life can be so wonderful, full of adventure and joy. It can also be full of challenges, setbacks and heartbreaks. Whatever our circumstances, we generally still have dreams, hopes and desires —that little something more we want for ourselves and our loved ones. Yet knowing we can have more can also create a problem, because when we go to change the way we do things, up come the old patterns and pitfalls that stopped us from seeking what we wanted in the first place.

    This tension between what we feel we can have and "what were seemingly able to have is the niggling suffering, the anxiety we feel. This is where we usually think it's easier to just give up. But we're never meant to let go of the part of us that knows we can have more. The intelligence behind that knowing is us—the real us. It's the part that believes in life and its possibilities. If you drop that, you begin to feel a little "dead" inside because you're dropping "you".

    So, if we have this capability but somehow life seems to keep us stuck, how do we break these patterns?

    Decide on a new course and make one decision at a time. This is good advice for a new adventure or just getting through today's challenges.

    While, deep down, we know we can do it, our mind—or the minds of those close to us—usually says we can't.

    That isn't a reason to stop, it's just the mind, that little man or woman on your shoulder, trying to talk you out of something again. It has done it many times before. It's all about starting simple and doing it now.

    Decide and act before over-thinking. When you do this you may feel a little, or large, release from the jail of your mind and you'll be on your way.
