Everybody has had at least one experience from which he knows the meaning of life.This time, which took place several years ago, but seems as if it just happened.

On an afternoon several years ago, my brother-in-law opened the bottom drawer of my sister's dress and picked out a beautiful skirt."Jan bought this the first time we went to New York, at least 8 or 9 years ago.She never wore it.She was saving it for a special occasion." he said.I guess this was the occasion: it was the funeral (葬禮) of my sister, after her unexpected death.

He took the shirt and put it on bed, with the other clothes we were taking to the funeral.Then he closed the drawer and turned to me, "Don't ever save anything for a special occasion.Every day you're alive is a special occasion."

I'm thinking about his words, and they've changed the way I live my life.I'm spending more time with my family and friends and less time in committee meetings.Whenever possible, life should be a kind of experience to enjoy, not to suffer."Someday" and "one of these days" are losing their importance on my vocabulary.If it's worth seeing or hearing or doing,I want to see and hear and do it now.

Ever since that day, I have been trying very hard not to put off, hold hack or save anything that would add laughter and color to our lives.Every morning when I open my eyes.I tell myself that every day, every minute, every breath, truly is a gift.So cherish every day and find the true meaning of your life.

Here are a few tips to help you, the workaholic, re-focus and get the best out of life.

EIGHT HOURS OF SLEEP! Make it a point to get at least eight hours of sleep and plenty of rest. Don't believe that you can always "catch some sleep or rest later." Your body cannot make up for lost sleep or rest time because it is not physiologically possible.

STRICTLY FAMILY ON WEEKENDS! Resolve to make Saturdays and Sundays strictly for family time. And stick to this! Mondays until Fridays you make an excuse not to relax and spend time with your family because it's work time, why not make a similar excuse for Saturdays and Sundays? "I can't work today because I'm spending time with my family."

GET SOME FOOD IN! Make sure you get food in your stomach. Workaholics are known to be food-skippers. If you can't afford to get off your desk or from doing paperwork, have food delivered to you. It's always a good idea if you have crackers on your drawer to ease the hunger pangs.

CONFINE WORK! Resolve to confine work in your office. Don't bring work to your home! Keep those files in your office desk where they belong. Practice working only within your working hours. If you have an eight-to-five working schedule, stick to it.

WORK UP THOSE MUSCLES! Exercise, exercise, exercise! Set aside at least an hour each day or every other day for exercise. You body needs to be conditioned, and working non-stop isn't going to give it the proper physical conditioning it needs. Since most workaholics tend to have their behinds stuck on their chairs, it's even more important that you get some exercise.

MAKE A PLAN! Plan your day. Work on only one or two things at a time. It's much easier to work on something and finish it first and then move on to the next rather than do a number of things all at the same time and never finish or accomplish anything at the end of the day. Make out a list of priorities. Write down things that need to be worked on immediately or are urgent, keeping the least ones at the bottom of your list. After you've done this, be guided by this list. Turning this activity into a habit will also help you manage your time better, be more organized, and accomplish more.

1.The passage is intended for ________.

A. those who are hardworking

B. those who consider work the center of their life

C. those who keep themselves healthy and alive

2.According to the passage, which of the following is not mentioned as a practical tip for a workaholic?

A. Don’t be food-skippers

3.By making a plan, the author mean ________.

A. working on only one or two things each day

B. finishing a number of things at once

This is VOA. The National Cryptologic Museum is on Fort George G. Meade, a military base near Washington, DC. The method of hiding exact meanings is called coding. People have used secret codes throughout history to protect important information. The National Cryptologic Museum celebrated 60 years of cryptologic excellence in 2012. One event there marked the sixtieth anniversary of the National Security Agency. Two former NSA workers shared their memories of operating a code machine called Sigaba.

In 1940, an American woman named Genevieve Grotjan found some information being repeated in Japanese coded messages. Her discovery helped the United States understand secret Japanese diplomatic messages. After the United States understood the code, it was possible to study messages from the Japanese ambassador to Germany and to his supervisors in Japan.

Understanding these messages helped the United States prepare for a possible war in the Pacific with Japan. After the attack on Pearl Harbor, an American Naval officer named Joseph Rochefort struggled to understand the Japanese navy code. He worked on the American base at Pearl Harbor. It was early in 1942. The American naval commander in the Pacific Ocean was Chester Nimitz. His forces were much smaller than the Japanese Naval forces. And the Japanese had been winning many victories. Joseph Rochefort had worked for several months to read the secret Japanese Naval code called JN-25. If he could understand enough of the code, he would be able to give Admiral Nimitz very valuable information.

From the beginning of 1942, the Japanese code discussed a place called "AF." Joseph Rochefort felt the Japanese were planning an important battle aimed at "AF." After several weeks, he and other naval experts told Admiral Nimitz that their best idea was that the "AF" in the Japanese code was the American-held island of Midway. Admiral Nimitz said he must have more information to prepare for such an attack.

The Navy experts decided to trick Japan. They told the American military force on Midway to broadcast a false message. The message would say the island was having problems with its water-processing equipment. The message asked that fresh water be sent to the island immediately. This message was not sent in code.

Several days later, a Japanese radio broadcast in the JN-25 code said that "AF" had little water. Joseph Rochefort had the evidence he needed. "AF" was now known to be the island of Midway. He also told Admiral Nimitz the Japanese would attack Midway on June 13.The battle that followed was a huge American victory. That victory was possible because Joseph Rochefort learned to read enough of the Japanese code to discover the meaning of the letters "AF."

One American code has never been broken. Perhaps it never will. It was used in the Pacific during World War Two. For many years the government would not discuss this secret code. Listen for a moment to this very unusual code. Then you may understand why the Japanese military forces were never able to understand any of it.

The code is in the voice of a Native American. The man you just heard is singing a simple song in the Navajo language. Very few people outside the Navajo nation are able to speak any of their very difficult language.

At the beginning of World War Two, the United States Marine Corps asked members of the Navajo tribe to train as Code Talkers.

The Cryptologic Museum says the Marine Corps Code Talkers could take a sentence in English and change it into their language in about 20 seconds. A code machine needed about 30 minutes to do the same work.

The Navajo Code Talkers took part in every battle the Marines entered in the Pacific during World War Two. The Japanese were very skilled at breaking codes. But they were never able to understand any of what they called "The Marine Code."

The Cryptologic Museum has many pieces of mechanical and electric equipment used to change words into code. It also has almost as many examples of machines used to try to change code back into useful words.

A. in 1940 B. 1942 C. in 1952 D. in 2012

Last week, while visiting my dad with my daughter, we went to a restaurant for dinner. When we were seated, my dad asked the waitress if there were any soldiers eating at the restaurant. Then waitress said there was a soldier having dinner with his friend. My dad told the waitress to tell the soldier and his friend that their dinner was paid for! He also said that he did not want to be known as the benefactor(施主).

Then waitress later commented on my dad’s thoughtful behavior saying that she had never seen anything like this before. At a local college, she had studied opera and so she used this to thank my dad by performing a piece from The Pearl Fisherman. Her voice brought me to tears because it sounded perfect!

After a while, the soldier appeared at our table (I don’t know how he knew my dad paid the bill for him.) and said that he would be sent to the front the next morning and that he could not leave this country without saying “thanks” to my dad. My dad replied that it was he who wanted to say “thanks”. They shook hands as the soldier left.

Before we left, the waitress came by again. She did a magic show as another way to show her “thanks” to my dad. Her show was really great. My dad left her a note with email address asking for her next performance time in addition to a $ 50 tip.

Everyone witnessed something exemplary(可作榜樣的) in the human spirit that night. I can only hope to see more of this in the future.
