I'm 30 years old, and there are several things that life has taught me that I want to share with you. Here are the 4 lessons that life has taught me in the past 30 years.

1 Take care of your body

      Life is “unfairly” biased (偏向的) towards people who “look good,” like it or not. So it's important that you do all that is in your power to look your best. {#blank#}1{#/blank#}You will live longer, and you will live happier, if you take care of your body; you may even get promoted faster on your job. Remember that your health is really your greatest wealth.

      No one taught me to save when I was growing up; no one told me the importance of saving. Fortunately I was able to learn the value of saving through reading great books like “The Millionaire Next Door”. What I want to teach others is to save at least twenty percent of your income. If you are tobe wealthy, you must not just earn a lot, you must save a lot.

3 Think in the long term

      In high school I was thinking about college, in college I was thinking about life after college. I'm designing my life and I'm making decisions today that will enable me to live the life I desire when I'm in my 40's, 50's and 60's. You have to think in the long term; you have to see the“big picture”.{#blank#}3{#/blank#}

4 Realize the power of focus

      Focus, focus, focus…{#blank#}4{#/blank#}If you fail in this lifetime, you will fail because of broken focus.If you focus on the goals that are most important to you, you will achieve them. The problem is that there are so many distractions.{#blank#}5{#/blank#}Winners decide to major on majors, and they even let important things slip, because they just focus on achieving whatis critical to their goals.

A．The importance of saving.

B．If you plan your future properly, you will live into your plans.

C．Save your money.

D．Nothing is more important than focus.

E．What separates the winners from the losers is that the winners learn to focus on their goals.

F．I mean dressing nicely, working out and eating right.

G．It's important that you pursue relationships with individuals who are good first.

Subject: My school

Hi, Li Zijun,

    Thanks very much for your email. I really enjoyed reading it. I think we have a lot in common. I wonder if our school life is similar too.

    I go to a big high school in Sydney called Maylands High School. There are about 1000 students and 80 or so teachers. My class has 25 students in it, which is normal for a Year 11 class. In the junior school there are about 30 students in a class.

    In the senior high school we have lots of subjects to choose from, like maths, physics, chemistry, biology, history, German, law, geography, software design, graphic arts and media studies. (Different schools sometime have different optional subjects.) English is a must for everyone and we have to do least three other subjects in Year 11 and 12. At the end of Year 12 we sit for a public exam called the High School Certificate.

    As well as school subjects, most of us do other activities at school such as playing a sport, singing in the choir or playing in the school band. We can also belong to clubs, such as the drama club, the chess club and the debating society.

    We have a lot of homework to do in senior school to prepare for our exam, so unless I have basketball practice, I usually go straight home and start studying. I arrive home about 4 pm, make myself a snack and work till 6. Then I help the family to make dinner and we all eat together. I'm usually back in my room studying by 8 pm. I stop at about 10 o'clock and watch TV or read a book for half an hour to relax. On Saturdays, I usually go out with my family or with friends and I sleep in till late on Sunday morning. Then it's back to the books on Sunday afternoon.

    How about you? What's your school life like? Do you have a lot of homework? What do you do to relax when you're not studying? I'm looking forward to finding out.

    With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dump, makes me feel good and warms my heart.

    How would you feel if you could not joke around with your wife, husband, child, co-worker, neighbor, close friends, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is common courtesy(礼貌)to speak to others that are around you.

    I know of a few people that don't have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the s lightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?

    Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to ignore the sadness and bring a little light into our lives. So, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.

    Every time a new year is coming, people set out to better themselves. They promise they will lose weight, find a new job, or maybe even take that vacation they've always talked about. But why do we make these promises to ourselves, and where did this tradition come from? Why does this tradition live on when so many people fail to keep the resolutions(决定) they made? Well, we can start by blaming the ancient Babylonians.

    Around 4, 000 years ago in Babylon, the earliest recorded celebration honoring the coming of a new year was held. Calendars weren't as they are today, so the Babylonians did it in late March during the first new moon after the Spring Equinox(春分). The festivities were meant for the rebirth of the sun god, but the Babylonians made promises in order to please their gods. They felt this would help them start the new year off well.

    Resolutions continued on with the Romans. When the early Roman calendar no longer synced(同步) up with the sun, Julius Caesar decided to make a change. He consulted with the best astronomers and mathematicians of the time and introduced the Julian calendar, which more closely represents the modern calendar we use today. Caesar declared January 1 the first day of the year to honor the god of new beginnings, Janus. The Romans celebrated the New Year by offering sacrifices to Janus.

To this day, the traditions of the ancient Babylonians and Romans continue around the world. So much that Google launched a Resolution Map in 2013 where people could add resolutions and see others adding theirs in real time. However, no matter how many people participated in Google's project, the numbers are bleak when it comes to the number of people who maintain their resolutions—-only eight percent of people are successful in sticking them out.

    Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.

    Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放)poisons that make people sick.

    Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.

    Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.

    When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.

    Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.

Singapore researchers say they have developed a form of electronic skin that can create a sense of touch. They hope their invention will give people with prosthetic hands (假肢手) the ability to identify different objects.

The skin device measures 1 square centimeter. The system contains 100 small sensors that attempt to recreate things like texture (质地), temperature and even pain. The researchers call the device Asynchronous Coded Electronic Skin, or ACES, which can process information faster than humans' nervous system. Machine learning methods trained the device to recognize 20 to 30 different textures. It can even correctly read Braille letters most of the time, the researchers say.

The system does not require the users' movement to work. Humans need to slide to feel texture. But in this case the skin, with just a single touch, is able to detect textures of different roughness.

A demonstration showed that the device could identify the difference between a soft ball and a solid plastic one. "When you lose your sense of touch, you essentially become numb and prosthetic users face that problem, " said Benjamin Tee, leader of the research team. "So by recreating an artificial version of the skin, for their prosthetic devices, they can hold a hand and feel the warmth and feel that it is soft."

Tee said his idea for the device came from the movie Star Wars, when character Luke Skywalker loses his right hand and it is replaced with a robotic one. In the film, the new hand is able to experience touch sensations just like the real one.

The artificial skin technology is still going through experiments and development. But Tee said there had already been a lot of interest in the system, especially from the medical community. Tee said similar inventions that his team has developed include see-through skin that can repair itself when torn and a material for wearable electronic devices that gives off light.
