Ireland has had a very difficult history. The problems started in the 16th century when English rulers tried to conquer (征服) Ireland. For hundreds of years, the Irish people fought against the English. Finally, in 1921, the British government was forced to give independence to the south of Ireland. The result is that today there are two "Irelands". Northern Ireland, in the north, is part of the United Kingdom. The Republic of Ireland, in the south, is an independent country.

    In the 1840s, the main crop, potatoes, was affected by disease and about 750,000 people died of hunger. This, and a shortage (短缺) of work, forced many people to leave Ireland and live in the USA, the UK, Australia and Canada. As a result of these problems, the population fell from 8.2 million in 1841 to 6.6 million in 1851.

    For many years, the majority of Irish people earned their living as farmers. Today, many people still work on the land but more and more people are moving to the cities to work in factories and offices. Life in the cities is very different from life in the countryside, where things move at a quieter and slower pace.

    The Irish are famous for being warm-hearted and friendly. Oscar Wilde, a famous Irish writer, once said that the Irish were “the greatest talkers since the Greeks”. Since independence, Ireland has revived (复兴) its own culture of music, language, literature and singing. Different areas have different styles of old Irish songs which are sung without instruments. Other kinds of Irish music use many different instruments such as the violin, whistles, etc.

    It was a hot day, and my brother Walt and I had decided that the only way to survive it would be to go swimming in a deep swimming hole across Mr. Blickez's Pasture（牧场）and through some woods.

    The only problem with our plan was that this pasture was guarded by a huge, mean Hereford bull（公牛）. Mr. Blickez had told us that Elsie was the meanest bull in the town, maybe even in the county, and we believed him. But the hotter it got, the more we thought there was something fishy about his words. For one thing, we remembered Mr. Blickez liked telling tall tales; for another, Elsie seemed like a strange name for a bull.

    Finally, I talked Mom into asking permission for us to walk through the pasture, but then another problem surfaced. Mom said she would talk to Mr. Blickez if we would take our cousin Joanie along with us. Joanie was almost two years older than me and a head taller. If her teasing ever got around my grade school, it would be all over for me. In fact, I still had a headache from a quarrel with her that morning. “I'm not going swimming with that silly girl cousin,” I told my mom.

    “Either Joanie goes with, or you stay home alone,” Mom said in her serious tone（语气）. I gave in and we set out. On your way across the pasture, Walt yelled suddenly. Elsie had approached him quietly and was licking（舔）his back. Joanie and I dove under the wire fence, but while I was on the ground I looked up and saw that Elsie wasn't a big mean bull after all. She was going to keep licking my brother's back as long as he stood still.

    We had many good days growing up and visiting our secret swimming hole guarded by the so-called “big mean bull”. And as it turned out, for a girl cousin, Joanie hasn't been too bad. She's been one of my best friends over the years.

    Psychology tells us that many people hate to take risks. But it is good for us to take risks, especially when the risk is to achieve a desired result. In that way, we become stronger and braver.

    Our human nature should be to take risks, but some people just sit and wish they didn't have the fear to move on. This is because they failed a few times in their lives. Please step out and don't let the past hold you back from living life to the fullest. Move forward and move on! In studying the psychology of taking risks, we find that human provides us with the desire to experiment and take chances.

    Risk taking is a great advantage that allowed our ancestors to become stronger and stronger day by day. By taking risks they fought off enemies and discovered new territories. This attitude has become a part of our modern culture. Riding a roller coaster is a common risk taking activity. Even each person seems to enjoy the risk although they have the understanding that it is dangerous. This psychological and biological connection creates an interesting connection between what is unsafe and what humans enjoy.

    Getting in a car each day is a risk. Getting out of bed is a risk, too. We need to take risks so that we can complete many things. Astronauts take risks when they get inside a rocket; however, the things they achieve are great. Businessmen take a risk when they buy parts of a company, however, without doing that, they could not make more money.

    We need to take risks so that we can gain something. It is impossible to move forward in life, earn money, enjoy a relationship, play a sport, or doing anything else without taking a risk. It is all part of the game. It's one of the most important parts of life.

    Canada is a very large country. It is the second largest country in the world. By contrast(比较)it has a very small population. There are only about 29 million people (by the year 1996) there. Most Canadians are of British or French origin, and French is an official language of Canada as well as English. About 45% of the people are of British origin, that is, they or their parents or grandparent, etc., come from Britain. Nearly 30% are of French origin. Most of the French-Canadians live in the province of Quebec.

    Over the years, people have come to live in Canada from many countries in the world. They are from most European countries and also from China, besides other Asian countries.

    However, Canada was not an empty country when the Europeans began to arrive. Canadian Indians lived along the coast, by the rivers and lakes and in forests. Today there are only about 350,000 Indians in the whole country, with their own languages. In the far north live the Inuit. There are only 27,000 Canadian-Inuit. Their life is hard in such a harsh climate.

    As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

    Three Chilean students got the idea for a plant-powered device(装置) to charge（使……充电） their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

    “It occurred to Camila to say about plants,” said inventor Evelyn Aravena. “'Why don't you have a socket, if there are so many plants? 'After that, we thought, 'why don't they have a charging outlet（插座）? Because there are so many plants and living things that have the potential to produce energy, why not?'”

    Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

    "It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.

    The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

    "Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

    But plants are everywhere, and the bio－circuit makes good use of their excess(过多的) power.

    The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

    The student inventors have applied for patents（专利） on their technology, and expect the E-Kaia to go on sale in the near future.

    When I was a boy, my parents and I traveled from New York City to the Pennsylvania countryside for a weeklong taste of rural life. We stayed in a guesthouse on a farm, joining the daily routines and eating meals with the farmer and his family. We got up early to see the cows as they were milked. I even tried my hand at milking one, and then joined the farmer as he released the cows into the field afterward.

    Decades later I still have vivid memories of that trip which made me realize the value of a vacation, of seeing new things, meeting new people and sharing memorable experiences with family members. To this day, I still consider that family trip when I plan to take time off with my wife and kids. Vacations are a time for resting and connecting. As a bank manager, I spend much of my workday encouraging my customers to save their money. One of the reasons I give is that we should all have enough for a family vacation every year. In our busy lives, family is what we should be saving our money and time for.

    For my family, our vacation starts when we begin planning the trip. We talk about destinations and our budget (预算) ahead of time. Among the things we discuss: Can we save money by renting a house instead of spending six nights in a hotel? Would it be better to buy groceries and cook for ourselves rather than eat out every night? Involving (使参与) the kids in planning the vacation makes sure that they have a great vacation too. I prefer to visit historical sites and museums while they love to fish and swim. So I build in some relaxation time for us all so that the vacation can work for everyone.

    Each year, setting aside vacation time to spend together is especially important to us. A relaxing environment opens the doors to all kinds of conversations—deep, silly or meaningful. There's no pleasure from the usual everyday tasks. What matters is that everyone is having a great time.
