Mark Twain was a great writer. He was from the USA. He was born in 1835. He was also a famous speaker. He was famous for his sense of humor. Many people liked to listen to him talk because he liked to tell some interesting stories to make people laugh all the time.

    One day Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he'd better not go there. Mark Twain waved (摇动) his hand and said, ＂It doesn't matter. The mosquitoes are not relatives of mine. I don't think they will come to visit me.＂

    After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about to have a rest, quite a few mosquitoes flew about him. The waiters felt very sorry about that. ＂I'm very sorry, Mr. Mark Twain. There are too many mosquitoes in our town.＂ One of them said to him.

    Mark Twain, however, made a joke, saying to the waiter, ＂The mosquitoes are very clever. They know my room number. They didn't come into the wrong room.＂ What he said made all the people present laugh heartily.

    But that night Mark Twain slept well. Do you know why? That was because all the waiters in the hotel were driving the mosquitoes away for him during the whole night.

    Living and dealing with kids can be a tough job these days, but living and dealing with parents can be even tougher.

    If I have learned anything in my 18 years, it is communication that is very important, both when you disagree and when you get along. With any relationship, you need to let others know how you are feeling. If you are not able to communicate, you drift apart. When you are mad at your parents, or anyone else, not talking to them doesn't solve anything.

    Communication begins with the concerns of another. It means that you can't just come home from school, go up to your room and ignore everyone. Even if you just say and see how their day was for five minutes, it is better than nothing.

    If you looked up the word “communication” in a dictionary, it would say “the exchange of ideas, the conveyance of information，correspondence (通信)，means of communication: a letter or a message”. To maintain a good relationship, you must keep communication strong. Let people know how you feel, even if ifs just by writing a note.

    When dealing with parents, you always have to make them feel good about how they are doing as a parent. If you are trying to make them see something as you see it, tell them that you'll listen to what they have to say, but ask them politely to listen to you. Yelling or walking away only makes the situation worse.

     This is an example: one night, Sophie went to a street party with her friends. She knew she had to be home by midnight after the fireworks, but she didn't feel she could just ask to go home. That would be rude. After all, they had been nice enough to take her along with them. Needless to say, she was late getting home. Her parents were mad at first, but when Sophie explained why she was late, they weren't as mad and let the incident go.

    Communication is the key factor here. If Sophie's parents had not been willing to listen, Sophie would have been in a lot of trouble. Communication isn't a one-way deal: it goes both ways. Just remember: if you get into a situation like Sophie's, tell the other person how you feel—listening is the key factor to communication.

    When I was five or six years old, I remember watching TV and seeing other children suffer in other parts of the world. I would say to myself," When I grow up, when I can get rich, I will save kids all over the world."

    At 17, I started my career here in America, and by the age of 18, I started my first charity( 慈善) organization. I went on to team up with other organizations in the following years, and met, helped, and even lost some of the most beautiful souls, from six-year-old Jasmina Anema who passed away in 2010 from leukemia(白血病), and whose story inspired thousands to volunteer as donors, to my grandmother, who lost her battle with cancer in 2012, and her death is the very reason and the driving force behind the Clara Lionel Foundation(CLF). We're all human. And we all just want a chance: a chance at life, a chance in education, a chance at a future, really. And at CLF, our mission is to impact as many lives as possible, but it starts with just one.

    People make it seem too hard to do charity work. The truth is, you don't have to be rich to help others. You don't need to be famous. You don't even have to be college educated. But it starts with your neighbor, the person right next to you, the person sitting next to you in class，the kid down the block in your neighborhood. You just do whatever you can to help in any way that you can. And today, I want to challenge each of you to make a decision to help one person, one organization, one situation that touches your heart. My grandmother always used to say. "If you've got a dollar, there's plenty to share."

    Everything about nuclear energy seems terrifically big: the cost, construction and decommissioning—and the fears of something going badly wrong.

    The future, however may well be much smaller. Dozens of companies are working on a new generation of reactors that, they promise, can deliver nuclear power at lower cost and reduced risk.

    These small-scale plants will on average generate between 50MW and 300MW of power compared with the 1,000MW-plus from a conventional reactor. They will draw on modular manufacturing techniques that will reduce construction risk, which has plagued larger-scale projects. Supporters believe these advanced modular reactors (AMRs)—most of which will not be commercial until the 2030s—are critical if atomic power is to compete against the rapidly falling costs of solar and wind.

    "The physics hasn't changed. It's about much cleverer design that offers much-needed flexibility in terms of operation," said Tim Stone, long-term industry adviser and chairman of Nuclear risk Insurers, which insures nuclear sites in the UK.

    Since the Fukushima meltdown in Japan in 2011, safety fears have threatened nuclear power. But the biggest obstacle today is economic. In western Europe, just three plants are under construction: in the UK at Hinkley point in Somerset; at Flamanville in France; and at Olkiluoto in Finland. All involve the European Pressurized Reactor technology of EDF that will be used at Hinkley Point. All are running years late and over budget. In the US, the first two nuclear projects under way for the past 30 years are also blowing through cost estimates.

    The UK, which opened the world's first commercial nuclear reactor in 1956, is one of the few western nations committed to renewing its ageing fleet to ensure energy security and meet tough carbon reduction targets. It is seen as a proving ground, by many in the industry, of nuclear power's ability to restore confidence.

    However, the country's agreement with EDF to build two units at Hinkley Point—which together will generate 3.2GW of electricity—has come under severe criticism over its cost. The government is looking at different funding models but said it still sees nuclear power as vital to the country's future energy mix. Small reactors, it believes, have the potential to generate much-needed power from the 2030s.

    A nuclear sector deal, unveiled last month, promised up to ￡56m in funding for research and development into AMRs and attracted interest of start-ups from around the world. The government hopes the funding will give the UK a lead in the global race to develop these technologies, helping to provide energy security while also creating a multibillion-dollar export market for British engineering companies.

    I believe children have a very pure sense of humor. Well, I would like to share my experiences with you.

    The other day when I was out with a friend and her daughter Jane at a restaurant, Jane ordered an apple dessert, which was the most attractive dish in that restaurant. However, when she had a bite of the pie, she shouted loudly, "Mom, why does it look good but tastes like rubber?" My friend was uneasy. Then the waiter gave us another dish.

    A child can say funny things. I was at a friend's home for tea and her son, Mark, wanted her to get up. His mom replied, "I can't, because my foot has fallen asleep now." Little Mark then sang a song and asked, "Mom, will it wake up now?" We laughed together.

    The other day we were having an interesting conversation over lunch and my friend, an animal activist (积极分子) , was arguing with another group member. Her son Tommy suddenly stood up, “Mom, people should never be allowed to shoot extinct animals!” That was funny and the child did manage to turn the argument into a pleasant conversation.

    Well, children sometimes really surprise us. I think we can have a lot to learn from them. They can help us understand the simple world through their eyes.
