Remember that goals are dreams with a timetable. Our goals are important for us to create what enriches our life. A very common attitude among people who are successful is that their success lies in their ability to provide themselves goals that are both numerous and exciting. When you think about your future，you are helping to feed a long-term goal of what you want to create.

    To realize your dreams，you must translate your vision into a series of actions you can take as soon as possible. You should be able to measure these results，to make sure they take you wherever you want. And this step should not be viewed lightly! Indeed，very few people set goals and concrete actions for themselves to achieve. Very few people note what they want to accomplish，and know each day whether they have indeed advanced in the direction of their dreams.

    Therefore one of the secrets that you can get results from is to write down your goals on paper first. When you give your dreams a form，they become more concrete，and you can refer to them often and easily. Whenever you read the dreams that you note down，you fill your mind with positive and motivational thoughts.

    Unfortunately，many people stop there. They just simply make wishes, hope and wait. These people do not bring positive difference in their lives，because that sort of behavior is just wishful thinking. Success is not at all a miracle. It depends on clear and realistic targets through serious thoughts：concrete actions and perseverance(毅力). Don't forget，your past does not determine your future. Only you now is your potential!

    Nowadays, parents worry a lot because their children spend hours and hours in front of the TV screen. Because this doesn't happen to only one specific family, many experts warn us that there can be some serious effects of children watching violence on television.

    Children who become addicted(上瘾的) to TV sit down and turn on the TV as soon as they get home. Although they have lots of homework, they become absorbed in TV programs.

    Since they spend tons of time watching TV, they have less time to enjoy real life activities such as playing with friends, playing outdoor sports, or enjoying other kinds of entertainment.

    There are too many violent scenes on TV. Some experts say there are 25 acts of violence per hour on TV. In addition, there are many experiments by psychologists which show how TV violence influences children. Finally, people worry that children tend to imitate what they watch on TV and may start to behave more violently.

    What should be done? First of all, the government should regulate TV violence. It should also encourage people to invent and develop new technology which can block violent scenes from the programs children watch. For example, with a rating system(分级制度) and the V-chip, unfit scenes of violence and sex can be blocked out. Second, parents should monitor what their children watch. At the same time, they should make their children interested in real life activities. Then when the children start to spend more time playing with friends or reading books, parents can stop their monitoring.

    It is a fact that there is more violence on TV today than there was ten years ago. Moreover, violent incidents occur more frequently in real life. It's time to realize how harmful watching TV violence is, and it's time to keep our children from watching violence.

    Last year DeepMind's AlphaGo programme took on and beat two of the world's best players of the Chinese game of Go（围棋）-an unbelievable achievement seen as a milestone in the development of artificial intelligence (A). That programme was trained by first giving it vast amounts of data from amateur and professional games.

    The new AlphaGo Zero began with a blank board and nothing but the rules of Go and set about playing against itself. Within three days it was so advanced that it took on the previous version, which had taken months to develop, and defeated it by a hundred games to zero.

    DeepMind says that creating knowledge from first principles without learning from human expertise（专门技能）is an important step in developing artificial intelligence. The company's founder Demis Hassabis said this breakthrough could help in real world problems such as designing new drugs or discovering new materials.

    In 1997, Garry Kasparov was defeated by Deep Blue, a computer program written by IBM, running on a supercomputer. This was the first time that a ruling world chess champion was defeated by a computer program in tournament conditions. Superficially, AlphaGo's win against Lee Sedol can be compared to Deep Blue's win against Gary Kasparov, which happened almost 20 years ago. So: what's the big deal? We have to understand the differences between chess and Go.

    In chess, each player begins with 16 pieces of six different types. Each piece of type moves differently. The goal of the game is to seize the other player's king. Go starts with an empty board. The goal of the game is to gain as much territory（领地）as possible.

    Although the rules of Go might appear simpler than those of chess, the complexity of Go is higher. Also, games usually last longer for lots of moves. A typical game in Go might last for 150 moves vs.80 in chess.

    Exciting screams of joy from two happy little girls rang across the beach. But I walked along, ignoring them. I'd come to this faraway beach on my sailboat, a place to escape. My marriage was in trouble. I worried about the harm to my two boys. But I didn't know how to make things better.

    “Help! Help!” The girls screamed. I saw one girl was at the edge of the surf, yelling. I charged into the waves, swam to her and seized her. “But where is the other girl?” I looked across the water and saw a small head after a big wave. I shifted the girl Td rescued to my back. She told me the other girl was her sister. For a moment I thought of my boys. How much they loved each other. How much I loved them.

    I quickened my swimming and held the second little girl. We were at least 50 yards from land. I couldn't swim that far with two girls hanging on to me. But there was no time to wait. I swam as hard as I could, but the weight of the girls grew heavier with every minute. My lungs burned. I opened my mouth to take a breath, but instead swallowed water. I couldn't breathe. From behind me I felt an unbelievable force, lifting.

    “Mommy!” The cry drew my attention. I looked up. An elderly man was trying to drag me out of the water. Two women were swimming toward shore. “Thank you,” one of the woman cried. “You saved my daughters.” My efforts and my struggles had paid off. I thought of that big wave, lifting me and pushing me. When my body had failed me, and when all hope was disappearing, I was given the strength I needed.

    I stoop up. My family were waiting for me. There were things I could do. I just needed to make an effort. The strength would be given to me.

    My wife and I spent two weeks in London last year. We went there in the autumn. We think it is the best season to visit England. The weather is usually good and there aren't too many tourists in October.

    We stayed in a small hotel in the West End. It was convenient as we did most of our sightseeing on foot. Taxis were too expensive, we couldn't understand the bus routes, and my wife didn't like traveling under the ground. She said it made her feel sick.

     We went to look at the places which all tourists visit. We saw Buckingham Palace and the National Gallery. We went shopping in Oxford Street and spent too much money. What we liked most, though, was going to the theatre. We didn't have the chance to see such wonderful plays at home. A lot of people say English food is bad. We didn't think so. It is true that most of the restaurants are French or Italian or Chinese, but we had some very good meals.

    In fact, we enjoyed our holiday so much that we have already booked again for this year. We are going to take our umbrellas, though. I'm sure we'll need them sometimes.

    Stocky, slow-moving whale, rarely grows beyond 15 metres in length

    Flippers are a third of body length; variable dorsal fin size and shape; saw-toothed trailing edge on flukes, often raised when diving

    Bumpy tubercles on top of head

    Body colour is dark brown to black; often extensive white on flippers and underside of body and flukes; such patterns enable individual recognition

    Bushy blow, occasionally V-shaped

    270-400 olive baleen plates

    Humpback whales belong to the rorqual (groove-throated) family, which includes fin, sei, Bryde's, minke and blue whales. The big family migrate between winter tropical breeding areas (North West Shelf, Great Barrier Reef, New Caledonia, Vanuatu, Fiii, Tonga) and summer Antarctic feeding areas. Once common in New Zealand waters, humpbacks are now rarely seen and may migrate further offshore. Males compete for mates either by physical fight or by song. Females give birth to their young every two to three years; some non-breeding females probably remain in the southern waters during winter. Young humpback whales return to their area of birth but in later life some wander between breeding areas. Humpbacks eat small shrimps and other schooling prey, such as fish, forming small, cooperative groups of two to three individuals to feed.

    Similar species: Easily identifiable due to a 'hump' back when submerging, but at a distance may be confused with other species that raise their flukes when diving, such as sperm, right and blue whales.

    Protection status: Recovering well from past whaling and now numerous in some former migration and aggregation areas, rarely seen in others.
