There was once a captain who loved money so much that he cheated his sailors at the end of every voyage and took their wages.

    On the last day of one voyage, the ship was in a small port. It was winter time, and the sea was very cold, so the captain said to his sailors, “If one of you stays in the water during the whole night, I will give him my ship. But if he comes out before the sun appears, I shall get his wages.”

    The sailors had heard about the captain's cheating, so they didn't trust him. But then one of them, who thought that he was cleverer than the captain, said that he would do it. He got into the water, and, though it was very cold, he stayed in it. When it was nearly morning, some fishermen lit a fire on the shore about half a mile away.

    “You are cheating,” the captain said to the sailor. “The fire's warming you.”

    “But it's half a mile away! ”said the sailor.

    “A fire's fire,” answered the captain. “I have won.”

    The sailor came out of the water, and said, “Perhaps you think that you are clever because you have won my wages, but you can't cook a chicken.”

    “I can, ”answered the captain.

    “If you cook this chicken,” said the sailor, “I shall work for you without wages for seven years, but if you can't, you will give me your ship.”

    The captain agreed, took the chicken and said, “Where's the fire?”

    “There it is,” answered the sailor. “On the shore.”

    “But it's half a mile away,” said the captain angrily.

    “ 'A fire's fire' you said,” answered the sailor. “If it is enough to warm me in the water, it is enough to cook your chicken.”

    You can tell a lot about a country from its passport. Color is the first give-away. Nations tend to pick colors that reflect their national character. New Zealand decorates its famous rugby team, its airline and its passports in the nation's favorite color—black. Many Islamic countries have green passports because of the importance of the color in the Muslim faith.

    But as well as a statement of national identity, color can show international cooperation. The British passport was originally a navy blue. But after Britain joined the European Union in 1973, it switched to burgundy red（酒红色）like other EU countries. The common color was supposed to make European passports instantly recognizable.

    But since colors can't be patented（专利）, nothing stops others with the same idea. A number of countries that long to join the EU have changed their passports to burgundy too. Meanwhile Britain has decided to leave the club. Its government has announced that the UK passports will return to navy blue after Breit（脱欧）.

    If you have a passport from Singapore or South Korea, you are in possession of one of the most powe3rful travel documents on earth. Passport power is measured by the number of countries the holder can access visa-free. Currently sharing first place in the power rankings, Singaporean and South Korean passports provide visa-free access to 162 countries each. British passport holders share fourth place in the power ranking with six other nations, each accessing 159 countries visa-free. Americans ranked fifth with access to 158. Somalia, Syria, Pakistan and Iraq are among the world's least powerful passports. Afghanistan is the lowest ranking of all, with visa0free access to just 26 countries.

    Having to get a visa is not a piece of cake. First there is the never-ending form. Then there are lengthy appointments and expensive fees. Some visas also require travelers to pre-booked flights to prove that they intend to return home.

    But there are unexpected advantages to some of the world's weaker passports. Middle-ranking Namibia is one of just a handful of countries, whose citizens can enter Angola visa-free. India is one of only three countries, whose citizens have visa-free access to Bhutan.

    A low-ranking passport limits your choices, but not your sense of adventure.

    Emma and Ryan, a married couple, were driving to a friend's house when Emma turned to Ryan and asked, “Would you like to stop for lunch?”

    Ryan replied. “No, I'm not hungry yet,” and continued driving. Meanwhile, Emma sat quietly fuming (十分恼火)in the passenger seat. Ryan could not understand why Emma was unhappy. He had thought she was asking if he was hungry, but in reality, Emma was telling him that she was hungry and wanted to stop for lunch.

    Misunderstandings like this often occur between men and women, even among people from the same culture. Deborah Tannen, professor of linguistics at Georgetown University in the United States, has studied conversational rules.

    In Emma and Ryan's situation, Emma was making a request in the form of a question. Her style of talking is common for women. She needed Ryan to agree they were both hungry. So, Emma asked Ryan what he wanted. She was really telling Ryan what she wanted; however, Ryan did not understand this. If he had been hungry, he would have said something more direct, such as, “I'm hungry. Let's have lunch.”

    Tannen believes that most women grow up in a world where talk is used to express feelings. However, most men are raised differently and they tend to keep their feelings to themselves.

    Tannen says, for men, talk is often used as a situation used outside the home to gain respect, to entertain and get attention , or to exchange information. This is why men communicate by making each other laugh, or talking about sport and work. These men do not always feel it is necessary to talk to feel close or to express their feelings. Women, on the other hand, are encouraged to speak about their feelings since this is a way to build relationships.

    I am sure we've all come across inspiring quotes（引言）that made us nod in agreement or made us think, "Wow, that's good quotes". But we end up going back to procrastinating（拖延）on whatever it was we were procrastinating on. So is it worthwhile to read these inspirational quotes? Well, that depends.

    Quotes, books, articles, audio programs… all of these things are just tools and they're only effective when you use them. I don't know about you but most quotes I read don't do anything for me. However, every now and then, I will come across one that will positively affect me in some way such as reminding me to be grateful, getting me to work out extra hard at the gym without being pressed by my wife, or never give up when things get tough.

      From my experience, reading quotes is more effective when you're actually trying to motivate yourself rather than just reading them for the sake of reading them. The second you feel the urge to take action, you'd better immediately get up off your chair and take action.

    These quotes aren't for everyone. If you have read tons of them and have never been motivated or had a positive change in the way you look at life or how you treat others, or these quotes don't help you to insist on doing something when you feel like giving up on it, then it's probably not worthwhile to read more of them. If you have done something a bunch of times and it's not giving you the results you want, don't keep doing it. Try something else.

    Now if you've found some value in reading these quotes in the past, continue to make them more effective by letting them guide your life.

    With only about 1,000 pandas left in the world, China is desperately trying to clone (克隆) the animal and save the endangered species (物种). That's a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called "Noah's Ark".

    Noah's Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A& M's College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

    It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

    This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

    The entire procedure could take from three to five years to complete.

    "The nuclear transfer (核子移植) of one species to another is not easy, and the lack of available (capable of being used) panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and ifs difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.

    "They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed."

You should try your best to create your own family library so that you and your family are always learning. "It is a great mistake to think that education is finished when young people leave school. Education is never finished even if you grow older," said Mrs Child in The Mother's Book. "Collecting a library of books in your home is really helpful to your family.”

"What is really interesting about having so many books in your home is that a book you purchase has a chapter about the deeper knowledge of your favorite subject at school," said a university graduate. Researchers in a study tries to identify what parents do has an influence on how well their children do on standardized tests. One positive aspect they find is the availability of a large number of books at home. This has a stronger connection, especially when you read to your children every day. The more books your older kids have access to at home, the more likely they are just to be reading for fun, rather than having to wait for weekly trips to the library.

John Henry, one educated parent, said, "I have been homeschooling my children using the philosophy of A Thomas Jeffer son Education. This philosophy of learning is based on the reading of classic books." Clinton Fadiman said, "When you reread a classic, you do not see more in the book than you did before; you see more in you than before." Classic books also make you smarter and wiser! The wisdom comes in the examples in the lives of the characters.

"It is within your power to guide your youth in their reading and to cultivate in their hearts a desire for good books. It is the most unfortunate if a person is not possessed with the desire for good reading. The reading habit, like charity, should begin at home," said Mrs Child.
