Have your parents ever inspected your room to see if you cleaned it properly? Imagine having your entire houses, garage, and yard inspected at any time -- with no warning. Inspections were a regular part of lighthouse (灯塔) living, and a keeper's reputation depended on results. A few times each year, an inspector arrived to look over the entire light station.  The inspections were supposed to be a surprise, but keeper sometimes had advance notice.
           Once lighthouses had telephones, keepers would call each other to warn that the inspector was approaching. After boats began flying special flags nothing the inspector aboard, the keeper's family made it a game to see who could notice the boat first. As soon as someone spotted the boat, everyone would do last-minute tidying and change into fancy clothes. The keeper then scurried to put on his dress uniform and cap. Children of keepers remember inspectors wearing white gloves to run their fingers over door frames and  windowsills looking for dust.
           Despite the serious nature of inspections, they resulted in some funny moments. Betty Byrnes remembered when her mother did not have
 time to wash all the dishes before an inspection. At the time, people did not have dishwashers in their homes. In an effort to clean up quickly, Mrs. Byrnes tossed all the dishes into a big bread pan, covered them with a cloth and stuck them in the oven. If the inspector opened the oven door, it would look like bread was baking. he never did.
          One day, Glenn Furst's mother put oil on the kitchen floor just before the inspector entered their house. Like floor wax, the oil made the
 floors shiny and helped protect the wood. This time, though, she used a little too much oil. When the inspector extended his hand to
greet Glenn's mother, he slipped on the freshly oiled surface. "He came across that floor waving his arms like a young bird attempting
its first flight," Glenn late wrote. After he steadied himself, he shook Glenn's mother's hand, and the inspection continued as though
 nothing had happened.

    Peter Thiel,the billionaire co-founder of PayPal,plans to live to be 120.Compared with some other tech billionaires,he doesn't seem particularly ambitious.Dmitry Itskov,the “godfather” of the Russian Internet,says his goal is to live to 10.000;and Sergey Brin,co-founder of Google,hopes to someday "cure death.

    They aren't being ridiculous.Their search is based on real science that could fundamentally change what we know about life and about death.It's hard to believe,though,since the human search for immortality is both ancient and filled with disastrous failures.Around 200 B.C.,the first emperor of China,Qin Shi Huang,accidentally killed himself trying to live forever;he poisoned himself by eating mercury（水银）pills.Centuries later, the search for eternal life wasn't much safer: In J492,Pope Innocent VIII died after blood transfusions from three healthy boys whose youth he believed he could absorb.

    But historical examples haven't discouraged some of the biggest names in Silicon Valley.Thiel,for example,has given $3.5 million to the Methuselah Foundation.Aubrey de Grey,Methuselah's co-founder,says SENS,the nonprofit's main research is devoted to finding drugs that cure several types of age-related damage:"Loss of cells, excessive（过多的）cell division,inadequate cell death,garbage inside the cell,garbage outside the cell,...The idea is that the human body,being a machine,has a structure that determines all aspects of its function,so if we can restore that structure—at the molecular（分子的）and cellular（细胞的）level—then we will restore function too,so we will have comprehensively renewed the body."

    But SENS,which has an annual operating budget of $5 million,is small,compared with the Brin-led Project Calico,Google's attempt to “cure death,”which is planning to pump billions into a partnership with medicine giant AbbVie.Google is secretive,but it's said to be building a drug to copy a gene associated with exceptional life span.

    Then there's the Glenn Foundation for Medical Research,started by Paul F.Glenn in 1965.Since 2007,the foundation has distributed annual "Glenn Awards,"$60,000 to independent researchers doing promising work on aging.The Glenn Foundation also works closely with the Ellison Medical Foundation,a far younger institution (founded in 1997).Ellison's passion project gives out hundreds of thousands of dollars each year to scholars seeking research on aging.Their decision to fund independent research may be paying off.Research projects funded by Ellison and Glenn appear to be developing into a testable means to stave off old age—for lab mice.The question is: Can those lab results be repeated in humans?

    Whether in your life or work, the following things are not the reasons for you to feel embarrassed. It's OK and just move on.

⒈Mistakes while learning

    There will be times when you have people above you(a boss) or even next to you(a coworker) that will get really annoyed with you for“ruining"  something "important".{#blank#}1{#/blank#} Even if you make mistakes and get a punishment, persevere and push on. You do not need to be embarrassed for learning from your mistakes.

⒉Food choices

    People are different and have different taste buds（味蕾）.Whether it is healthy or not, food is a choice and it is part of life.{#blank#}2{#/blank#}  You do not need to be embarrassed for food you do or do not like. Tell them, "It is a personal choice I have made, and I am committed to it.”

⒊Your past

    Allowing positive experiences to define, limit, improve, and outshine（凸显）you may cause you to be caught up in the past and unable to truly live in the present. Whether your history is positive, negative, or somewhere in between, don't hold on to the negative experiences and let it reflect your current behavior，{#blank#}3{#/blank#}

⒋The clean lines of your car／home／workspace

    When everyone gets in the car, you realize your Starbuck bags are still on the floor. So what? Think about it this way: everyone has a "messy" aspect of their life. Maybe their home is completely clean, but the relationship with their spouse（配偶）is messy. Someone's car gets washed once a week, but his/her work life could use some help.{#blank#}4{#/blank#} We don't apologize to others about our personal limitations. By being outwardly embarrassed, it only brings more attention to the fact!

⒌Putting yourself first

    If you find yourself saying no to something or making up lies to get out of it,tell them the truth,  and don't apologize. You will feel much better in the long run if you are honest with them and yourself. If you're not up to a voluntary duty, you don't have to be. You can politely refuse the person's request.

    {#blank#}5{#/blank#} Put yourself first.

A. It is simply a personal choice that people make for their own reasons.

B. It is okay to be selfish from time to time.

C. Errors are bound to happen when you have on your training wheels.

D. Each of them waits for your immediate help.

E. Let bygones(过去的事)  be bygones.

F. Forgetting history means betrayal.

G. No one on Earth lives a perfectly "clean" life in every aspect.

    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.

    Darwin noted that some human emotional expressions might have started as part of a physiological function: for example, exposing the teeth to bite food. The function, however, took on meaning and became a form of communication which signals anger.

    The same may be true for the animals. Baby monkeys cry for attention. They also cry to signal to an adult that they want to be carried.

    “Chimpanzees do make upset voice when they are being weaned (断奶) by their mothers or have lost their mothers or another individual,” says Anne Pusey, a professor at the University of Minnesota. “They whimper (呜咽) and cry and scream. When we hear these calls, the emotion involved seems obvious. However, they do not weep in the sense of producing tears. I have seen an adolescent male whimpering when he lost sight of his older brother with whom he had been traveling.”

    Babies of many mammalian species, including rats, cry. Moreover, when a baby rat cries, often his mother brings the fallen pup back into the nest. This is probably a straightforward communication, as it is with humans. However, psychologists at the University of Iowa aren't convinced.

    The Iowan researchers can cause the same crying sounds by producing large decreases and then increases in blood flow. The blood flow also goes down when baby rats get cold. Thus, they conclude baby rats cry in the same way that we sneeze. Of course the rat baby could be crying because he's cold and wants his mother to know.

    “All young mammals make cries when separated from their mother,” says Jaak Panksepp, a psychologist at Bowling Green State University. “If you're willing to call this crying, then certainly other animals show this emotional response.” he says, “Some of us take seriously that animals do have emotions.”

Mrs. Black was having a lot of trouble with her skin, so she went to her doctor about it. He could not find anything wrong with her, however. So he sent her to the local hospital for some tests. The hospital, of course, sent the results of the tests direct to Mrs. Black's doctor, and the next morning he telephoned her to give her a list of the things that he thought she could not eat, as any of them might be the cause of her skin trouble. Mrs. Black carefully wrote all the things down on a piece of paper, which she then left beside the telephone while she went out to a ladies' meeting.

When she got back home two hours later, she found her husband waiting for her. He had a big basket full of packages beside him, and when he saw her, he said, "Hello, dear. I have done all your shopping for you." "Done all my shopping?" She asked in surprise. "But how did you know what I wanted?" "Well, when I got home, I found your shopping list beside the telephone," answered her husband. "So I went down to the shops and bought everything you had written down."

Of course, Mrs. Black had to tell him that what he had thought were all the things the doctor did not allow her to eat.
