Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires—not that you cannot satisfy your tastes but that you don't have enough tastes.

    Real riches consist of well-developed and hearty capacities (能力) to enjoy life. Most people are already swamped(淹没) with things. They eat, wear, go and talk too much.They live in too big a house with too many rooms, yet their house of life is a deserted hut.

    Your house of life ought to be a mansion (豪宅) , a royal palace.  Every new taste, every additional interest, every fresh enthusiasm adds a room.  Here are several rooms your house of life should have.

    Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of ham and eggs when you're hungry.

    Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but who likes a library.

    Music like Mozart's and Bach's shouldn't be absent. Real riches are of the spirit. And when you've brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills.

    Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the had days, if you could, and did, play a bit.

    Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding.

    Every day millions of letters go from one country to another. Letters mailed in Italy are received in Japan. Letters mailed in Canada are received in Africa. On the letters there are many different kinds of stamps, bought in different countries.

    The Universal Postal Union helps each letter get to the right place as quickly as possible. It sets up rules about the size and weight of letters, postcards, and small packages. It has rules that all countries must follow about international postal rates.

    On hundred years ago international mail did not move so smoothly. One country did not always accept another country's letters. Letters from some countries were too large to fit into the mailboxes of other countries. Letters traveled by many different routes. Some were lost along the way.

    Sometimes the person who sent the letter could pay only part of the postage. The person receiving the letter had to pay the rest.

    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

    A mother stared down at her son who was dying of terminal leukemia (白血病). Like any parent she wanted her son to grow up and realize all his dreams. She took her son's hand and asked, "Bopsy, did you ever think about what you wanted to be when you grew up?"

    "Mommy, I always wanted to be a fireman when I grew up."

    Mom smiled back and said, "Let's see if we can make your wish come true." Later that day she went to her local fire department in Phoenix, Arizona, where she met Fireman Bob. She explained her son's final wish and asked if it might be possible to give her six-year-old son a ride around the block on a fire engine. Fireman Bob said, "Look, we can do better than that. If you'll have your son ready at seven o'clock Wednesday morning, well make him an honorary fireman for the whole day, He can come down to the fire station; eat with us, go out on all the fire calls, the whole nine yards! And, if you'll give us his sizes, we'll get a real fire uniform made for him."

    Three days later Fireman Bob picked up Bopsy, dressed him in his fire uniform and escorted（护送）him from his hospital bed to the waiting hook and ladder truck. Bopsy got to sit up on the back of the truck and help steer it back to the fire station. He was in heaven.

    There were three fire calls in Phoenix that day and Bopsy got to go out on all three calls. He rode in the different fire engines and even the fire chief's car. Having his dream come true, with all the love and attention that was lavished（慷慨给予）upon him, Bopsy lived three months longer than any doctor thought possible.

    One night all of his vital signs began to drop and the head nurse began to call the family members to the hospital. Then she remembered the day Bopsy bad spent as a fireman, so she called the fire chief and asked if it would be possible to send a fireman in uniform to the hospital to be with Bopsy as he made his transition. The chief replied, "We can do better than that. We'll be there in five minutes. Will you please do me a favor? When you hear the sirens（警报器）screaming and see the lights flashing, will you announce over the PA system that it's just the fire department coming to see one of its finest members one more time? And will you open the window to his room? Thanks?"

    About five minutes later a hook and ladder truck arrived at the hospital, extended its ladder up to Bopsy's third floor open window and 14 firemen and two fire-women climbed up the ladder into Bopsy's room. With his mother's permission, they hugged him and held him and told him how much they loved him. With his dying breath, Bopsy looked up at the fire chief and said, "Chief, am I really a fireman now?"

    "Bopsy, you are," the chief said. With those words, Bopsy smiled and closed his eyes for the last time.

    When international aid is given, steps must be taken to ensure（确保）that the aid reaches the people for whom it is intended. The way to achieve this may not be simple. It is very difficult for a nation to give help directly to people in another nation. The United Nations Organization （UNO） could undertake to direct the distribution of aid. Here however rises the problem of costs. Also tied with this is time. Perhaps the UNO could set up a body of devoted men and women in every country who can speedily distribute aid to victims of floods and earthquakes.

    More than the help that one nation can give to another during a disaster, it would be more effective to give other forms of help during normal times. A common proverb says, "Give me a fish and I eat for a day, teach me to fish and I eat for a lifetime." If we follow this wise saying, it would be right to teach people from less developed nations to take care of themselves. For example, a country could share its technology with another. This could be in simple areas like agriculture or in more complex areas like medical and health care or even in building satellites. Even a small country is able to help less developed nations. Sometimes what is taken for granted, like the setting up of a water purification plant or the administration of a school, could be useful for countries which are looking about to solve common problems. It does not cost much to share such simple things. Exchange students could be attached for a number of months or years and learn the required craft while on the site. They can then take their knowledge back to their homelands and if necessary come back from time to time to clear doubts or to update themselves. Such aid will be truly helpful and there is no chance of it being temporary or of it falling into the wrong hands.

    Many countries run extensive courses in all sorts of skills. It will not cost much to include deserving foreigners in these courses. Besides giving effective help to the countries concerned, there is also the build­up of friendships to consider. Giving direct help by giving materials may be effective in the short run and must continue to be given in the event of emergencies. However, in the long run what is really effective would be the sharing of knowledge.
