It happened to me recently. I was telling someone how much I had enjoyed reading Barack Obama's Dreams From My Father and how it had changed my views of our President. A friend I was talking to agreed with me that it was ,in his words, “a wonderfully written book ”. however, he then went on to talk about Mr. Obama in a way which suggested he had no idea of his background at all .I felt that I was talking to a book liar.

    And it seems that my friend is not the only one. Approximately two thirds of people have lied about reading a book which they haven't .In the World Book Day's “Report on Guilty（愧疚的） Secrets”, Dreams From My Father is at number 9.The report lists ten books, and various authors, which people have lied about reading, and as I'm not one to lie too often (I'd hate to be caught out ),I'll admit here and now that I haven't read the entire top ten .But I am pleased to say that, unlike 42 percent of people, I have read the book at number one ,George Orwell's 1984.I think it's really brilliant.

    The World Book Day report also has some other interesting information in it. It says that many people lie about having read Jane Austen, Charles Dickens, Fyodor Dostoevsky(I haven't read him, but haven't lied about it either )and Herman Melville.

    Asked why they lied, the most common reason was to “impress” someone they were speaking to. This could be tricky if the conversation became more in –depth!

    But when asked which authors they actually enjoy, people named J.k. Rowling, John Grisham, Sophie Kinsella(ah, the big sellers, in other words).Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing the story(I'll come clean: I do this and am astonished that 58 percent said they had never done so).

    We walked in so quietly that the nurse at the desk didn't even lift（抬起）her eyes from the book.Mum pointed at a big chair by the door and I knew she wanted me to sit down.While I watched,mouth open in surprise.Mum took off her hat and coat and gave them to me to hold.She walked quietly to the small room by the lift（电梯）and took out a wet mop（拖把）.She pushed the mop past the desk and as the nurse looked up.Mum nodded and said,"Very dirty floors."

“Yes.I'm glad they've finally decided to clean them,”the nurse answered.She looked at Mum strangely and said. “But aren't you working late?”

    Mum just pushed harder,each swipe of the mop taking her farther and farther down the hall.I watched until she was out of sight and the nurse had turned back to writing in the big book.

    After a along time Mum came back.Her eyes were shining.She quickly put the mop back and took my hand.As we turned to go out of the the door,Mum nodded politely to the nurse and said.“Thank you.”

    Outside,Mum told me, “Dagma is fine.No fever."

     “You see her,Mum?”

     “Of course.I told her about the hospital rules,and she will not expect us until tomorrow.Dad will stop worrying as well.It's a fine hospital.But the floors!A mop is no good.You need a brush."

    It may not come as a surprise but the world as a whole is getting richer. Some people have more disposable(可支配的) income to spend on luxuries such as holidays, cars, TVs and smartphones. Recent data has shown that the number of people living in extreme poverty(贫穷) has halved in recent decades. So should we celebrate the fact that more of us now have a better standard of living?

    Maybe not. Whilst the gap between rich and poor in some countries is narrowing, there is still a lot of inequality in other places-some people have a lot of money and opportunities and others don't. A recent report by Oxfam and Credit Suisse revealed how divided many of us are when it comes to wealth. A lot of the money in the world is in the hands of very few people. In fact, 48% of global wealth is owned by the richest 1% of the population.

    But some countries are attempting to reduce this inequality and make the poor, less poor. According to David Bryer from Oxfam, Brazil has been taking "some really sensible measures-measures around having more progressive(逐步发展的) tax, around investing in a higher minimum wage and investing in central public services." Having a higher minimum wage, can help people eat better and seek a better education. And more people with more money buy more things-and factories can produce more. In turn, a factory which produces more will need more workers. So, more jobs are created.

    Other wealthy individuals are doing their bit to help reduce inequality. Bill Gates, the founder of Microsoft, earned a lot of money from his company but when he retired, he and his wife Melinda, created a foundation to help the poor. He thinks that rich people should, of course, pay their taxes but he also advises that they should all "look at taking their wealth and being philanthropic, both in their own country and to help the global poorest."

    Bill Gates feels that giving money to help poor people is "fulfilling". But if other super-rich people don't want to experience this fulfilment then, according to Oxfam, very soon the wealthiest 1% will soon own more money than the rest of the world's population.

    Killer whales in Alaska's Bering Sea have figured out an easy way to get fed. Instead of seeking out the fish them- selves, the clever whales chase down fishing boats and steal the entire catch of the day, as much as 20,000 to 30,000 pounds.

    Killer whale “thieves” are not a new phenomenon. Japanese fishermen have reported being followed by killer Whales since the 1950s. However, the increasing frequency of whale fish theft in the Bering Sea's continental shelf is now threatening the livelihood of fishermen.

    Paul Clampitt, a local fisherman, says his crew tried to keep the whales away with loud sounds. Though that worked for a short time, the whales now consider the noise “ a dinner bell”. Jay Herbert tried using sonar to keep the whales away. He also met with little success. According to the experienced fisherman, the smart whales deliberately seek out longliners (延绳钓渔船）, and, all the first opportunity presented to them, steal the fish, leaving behind just the lips of the fish caught!

    NOAA Fisheries biologist John Moran is not surprised at the whales' thieving skill. The expert says whales are skilled hunters who can distinguish the sounds of different boats and even recognize the sounds of the operating system that places the fishing equipment into the ocean. The expert jokes, “ Grabbing a fish off a line is nothing.” Since they are social animals, it is easy for whales to pass their skills on to others.

    Killer whales are not the only whale species that have learned to steal from humans. In the Gulf of Alaska, sperm whales also conduct similar thefts. Longline fishermen off Washington, Chile, Australia, Hawaii, and many other countries have reported similar incidents. There is, unfortunately, no easy fix to this problem. One of the possible solutions is using pot traps similar to the ones used to catch crabs. However, the cost of switching from longline to pot fishing is too high, especially for small-scale fisheries. There is also no guarantee that the catch will be safe from the intelligent whales which, many fear, will eventually figure out how to open the pots!

    New Zealand's government is hoping to make the nation greener by planting 100 million trees each year, ensuring the electricity grid（电网） runs entirely from renewable energy, and spending more money on cycle ways and rail transport. The government's plan is to reduce its net greenhouse gas emissionto zero by the year 2050.

    New Zealand's prime minister Jacinda Ardern has set ambitious environmental policies to confronta warming planet. “We will absolutely focus on the challenge of climate change,” said Ardern. “That will include a zero carbon government policy. That will include an independent climate commission. That will include making sure that we have an all gases, all sectors emissions trading scheme,” she added. According to the Associated Press (AP), Arden said the goal of doubling the amount of trees the country plants each year is “absolutely achievable.”

    Not everybody is happy with the plans. Many farmers are worried they will be required to pay more if they are absorbed into an emissions trading plan. “There is concern that if this should happen, New Zealand will become less competitive with other food-producing nations.” said Katie Milne, the president of Federated Farmers.

    More than 80 percent of New Zealand's electricity already comes from renewable resources. The AP reported that Ardern wants to increase it to 100 percent by 2035, in part by investing more in solar, which currently takes up only 0.1 percent of the country's total renewable energy slice.

    I was reading these interesting stories behind a group of great logos（商标） in the world. Personally Nike is my favorite one﹣it's so simple. And I liked the stories behind them, which made me forget all other things. McDonald's, Apple, and Mercedes Benz own great logos as well, and they are among my favorites.

    Nike

    In the Greek myth, Nike is the goddess of victory and the source of inspiration for soldiers. This logo represents the wing in the famous statue of the Greek goddess.  Nike's logo was designed by Carolyn Davidson in 1971 for﹩35, and was registered as a trademark in 1995.

    McDonald's

    The logo was designed in 1962 by Jim Schindler to resemble the arch shaped （拱形的） signs on the side of the company's then walk﹣up hamburger stand. Later on, the two golden arches were combined together to form the M. The McDonald's name was added to the logo in 1968.

    Apple

    There are different stories behind Apple's logo. The first logo was a reference to the religious story of Adam and Eve, in which the apple represented the fruit of the Tree of Knowledge. One year later, the second logo was designed in 1977 by Steven Jobs and Ronald Wayne, and it described Sir Isaac Newton sitting under an apple tree. This logo didn't stay long. One year later it was replaced almost immediately by graphic designer Rob Janoff's "rainbow apple",  a rainbow﹣colored silhouette （轮廓） of an apple with a bite taken out of it. And then the rainbow﹣colored apple was replaced by the one﹣colored logo in 1998. It has not been changed so far.

    Mercedes Benz

    The Mercedes Benz logo, which was originally created by Gottlieb Daimler in 1909, consists of a simple description of a three﹣pointed star that represents its rule of the land, the sea and the air. The company was founded by Gottlieb Daimler and Wilhelm Maybach. Mercedes is the name of Maybach's elder daughter, while Benz came as a result of a combination with Benz Cie and DMG in 1926.
