The deadliest Ebola outbreak in history that has so far killed almost 1000 people in Guinea, Liberia, Sierra Leone and Nigeria in West Africa has caused fear around the world.

    The outbreak is unprecedented（空前的）both in infection numbers and in geographic scope. Officials from the World Health Organization (WHO) said earlier this month the outbreak “is moving faster than our efforts to control it”, reported CNN. So far, the battle against the virus doesn't appear to be slowing down.

    The Ebola virus is terrifying no matter where it strikes: It's a disease with no cure that causes headaches and fever, severe diarrhea(腹泻), vomiting and bleeding and has been known to kill up to 90 percent of its victims.

    It is understandable for people to be panicked, but those living outside Africa shouldn't be particularly concerned about contracting the virus, says a Washington Post article.

    This is because transmission of Ebola requires direct contact with an infected person's blood, vomit or other bodily fluids during the period that he or she is contagious(接触传染的). It is something that is extremely unlikely for anyone but healthcare workers. The virus is not spread by coughing or sneezing.

    Media outlets in the US and the UK are using terrifying headlines, wrongly claiming that people infected with the virus have traveled to their countries.

    James Ball at The Guardian says the Ebola outbreak in Africa is tragic, but it is important to keep a sense of proportion. Other infectious diseases, including common influenza, are far, far deadlier.

    Most buildings are built to stand up straight, but these look as if they might fall over!

The church tower of Suurhusen

    Built in 1450, the 27-meter-high church tower lies in Suurhusen, Germany. It was built in wet land on foundations of oak tree trunks (树干). When the land was drained (排水) later, the wood broke down, causing one side of the tower to be a little lower than the other. In 1975, the tower became a real hazard and people were not allowed to enter until the foundations were made strong again. The lean (倾斜) of the tower is now about five degrees.

The Leaning Tower of Pisa

    The work of building the tower began in 1173, and was finally completed in 1372. In fact, it began to lean after just a couple of floors were built. And this condition continued in the centuries after its completion. The tower was finally closed to the public in 1990 after people failed to stabilize (使稳固) its foundations. In 2001, it was reopened after engineers removed soil from underneath its raised side. Now it leans just an angle of 3.97 degrees.

Capital Gate of Abu Dhabi

    Completed in 2011, the Capital Gate tower in Abu Dhabi was designed to lean eighteen degrees. The building stands next to the Abu Dhabi National Exhibition Centre and contains, among other things, a fine hotel with wonderful views of the harbour. Also known as the leaning tower of Abu Dhabi, the tower is one of the tallest buildings in the city.

Big Ben of London

    The building leans 0.26 degrees to the northwest. This is mainly caused by the engineering projects that have been carried out in the ground below it since the late 1800s. The tower, which has been continuously open since it was completed in 1858, has nowhere near the lean of the Tower of Pisa and is still completely safe to enter.

    When I was young I wanted to be a model,so when a national contest was staged,I convinced my parents to have a try.I was selected and told that I was talented and that for only $900 I could attend a weekend event which dozens of the most famous modeling agencies from around the world would attend.At 13,my hopes of fame and fortune clouded all judgment and I begged my parents to let me go.We have never been rich,but they saw my enthusiasm and agreed.

    I imagined being signed by some famous model companies.For months,any boredom or disappointment I faced was pushed aside because I knew I would soon have the chance to be a real model.I thought I would grace the covers of famous magazines!

    Of course,I wasn't signed,but what hurt the most was being told that if I grew to about 1.75metres I could be a success.I prayed for a growth spurt（冲刺）because I could not imagine giving up my dream.I made an appointment with a local modeling agency and the agent demanded $500 for classes,$500 for a photo shoot,and $300 for other expenses.My parents only agreed after hours and hours of my begging.

    The agency sent me out on a few auditions,but with every clay I didn't receive a call,I grew more depressed.The final straw came in July after I had decided to focus on commercial modeling.There was an open call in New York City.We spent hours driving and another few hours waiting,only to be told that I was too short.I was depressed.

    Years later,I realized that the trip to New York was good as it made me notice I didn't actually love modeling, just the idea of it.I wanted to be special and I was innocently determined to reach an impossible goal.The experience has made me stronger and that will help me in the future.

    Eudaimonia is an Ancient Greek word, particularly stressed by the philosophers Plato and Aristotle, which deserves far more attention than it has because it corrects the shortfalls (缺失)in one of the most central, but troubling words in our modem language: happiness.

    When we nowadays try to clearly express the purpose of our lives，it is the word "happiness" that we commonly turn to. We tell ourselves and others that the most important principle for our jobs, our relationships and the conduct of our day-to-day lives is the pursuit of happiness. It sounds like an innocent enough idea, but too much reliance on the term means that we frequently unfairly tend to quit or, at least, heavily question a great many challenging but worthwhile situations. The Ancient Greeks did not believe that the purpose of life was to be happy; they proposed that it was to achieve Eudaimonia, a word which has been best translated as "fulfilment".

    What distinguishes happiness from fulfilment is pain. It is very possible to be fulfilled and—at the same time—under pressure, suffering physically or mentally, overburdened and, quite frequently, in an irritable (易怒的)mood. This is a slight psychological difference that is hard for the word "happiness" to capture, for it's tricky to speak of being happy yet unhappy, or happy yet suffering. However, such a combination is readily accommodated within the respected and noble-sounding idea of Eudaimonia.

    The word encourages us to trust that many of life's most worthwhile projects will sometimes be in conflict with contentment, and yet will be worth pursuing. Properly exploring our professional talents, managing a household, keeping a relationship going, creating a new business venture or engaging in politics... none of these goals are likely to leave us cheerful and grinning on a daily basis. They will, in fact, involve us in all manner of challenges that will deeply exhaust and weaken us, provoke (激怒)and wound us. And yet we will perhaps, at the end of our lives, still feel that the tasks were worth undertaking. Through them, we'll have achieved something deeper and more interesting than happiness.

    With the word Eudaimonia in mind, we can stop imagining that we are aiming for a pain-free existence—and then blaming ourselves unfairly for being in a bad mood. We'll know that we are trying to do something far more important than smile all the time: we're striving to do justice to our full human potential.

    Resorts of every kind have sprung up to cater to the Englishman need to spend a part of the year, however briefly, by the seaside. No town in Britain is more than eighty miles from the sea and there are seaside resorts all round the coast. On a summer Sunday most of the roads that lead to the sea axe congested (拥挤) with cars full of people eager to get a breath of sea air. In the evening when everyone is full of food, ice-cream and lollypops, there is the long slow drive home on roads crowded with returning cars.

    Brighton

    Brighton is one of the best-known south coast resorts and is very popular for day trip excursions. It is only fifty miles from London and can be reached by fast train in an hour. At the weekend the pebbled beaches are thronged with people sunbathing or picking their way to the water's edge for a dip.

    Bournemouth

    Located a hundred miles from London, the beaches are wide and sandy. White houses line the cliff tops and narrow valleys, densely wooded with pine trees, reach down to the shore. The area near to the town of Torquay on the Devon coast is sometimes called Britains Riviera and the climate is so mild that palm trees grow along the sea front.

    Blackpool

    On the north-west coast, a popular resort for the people in the industrial north, Blackpool is a gay, noisy town, famous for its amusement facilities and the magical lights. At night people travel from miles around to see the extravaganza of lights decorating the sea front.

    Southend

    On the east coast at the mouth of the Thames, Southend is, like Brighton, one of the favorite resorts of Londoners. The pier here is the longest in Britain and offers a great variety of differing entertainments.

    Memory, they say, is a matter of practice and exercise. If you have the wish and really make a conscious(自觉的) effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.

    Sometimes you remember things that really did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remember locking it carefully the night before.

    Memory "tricks" work the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.

    We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years, and we never get tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny. There are times when "tricks" of our memory can cause us great trouble.
