At 80 years old，scientist Jane Goodall continues to enjoy the joy of discovery.“Trees can communicate with each other，” she said during her Nov.16，2014 China visit to celebrate the 20th anniversary of the China establishment of her youth organization Roots & Shoots，which has grown to more than 600 branches in the country among 150，000 active groups globally.

    Jane Goodall still travels 300 days a year in all around the world and says she absorbs energy from the inspired people she meets in each country.The elderly activist and the youth take inspiration from each other.

    On Nov.16，2014，she visited the project of Roots & Shoots which was set up in Beijing.“She thought our project was great，” says 16－year－old Beijing Experimental High School student Qi Zhengyang，whose group helps protect a wetlands in the suburbs of Beijing.“She said we're doing a good job.She paid attention to us.”

    Jane Goodall plans to continue to set up Roots & Shoots branches as many as possible throughout the world.“I'll go on as long as I can，” she says.“I hope I maintain physical health as long as possible because there's so much to do.” Her aspiration for the organization in China is to expand in rural areas.Most branches are in big cities as Beijing and Shanghai.

    It was publishing her findings about chimpanzees (My Friends the Wild Chimpanzees)  more than half a century ago that made Jane Goodall a household name in the world.She was named United Nations Messenger of Peace in 2002.

    Some of the members in Roots & Shoots realize Goodall is 80 and has already considered who'll lead the movement once she's gone.“It can be all of us，” she says.“A group is stronger than one person.We can do more working together.”

    Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?

    In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.

    Passionate love is rooted in the reward circuitry of the brain—the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner.

    What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman's reproductive health.)

    Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.

    One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.

    There are many dangerous sea creatures in the world. The following are some examples.

    The needlefish are commonly seen living near the surface of tropical (热带的) waters. But they can also break cover the water，and once in the air they can become dangerous flying swords. Though it is rare，people have been seriously hurt and even killed by the fish．Night fishermen in small boats are at particular risk because their lights may attract the fish.

    Saltwater crocodiles are the world's largest crocodiles，sometimes reaching 23 feet in length and topping 2，200 pounds. Yet these crocodiles hunt quietly，lying in wait below shoreline waters to attack turtles and thirsty animals that have come to drink. Saltwater crocodiles kill a number of people each year.

    There is no doubt that the great white shark sits atop the ocean food chain. The world's largest fish can weigh at over 5，000 pounds and reach lengths of more than 20 feet. Great white sharks have about 3，000 teeth，which they typically sink into sea lions，seals，and sea turtles. These sharks are responsible for a third to a half of the 100 shark attacks on humans every year.

    The sea anemone (海葵) may look like the beautiful flower for which it's named，but fish that swim too close may regret it. The sea anemone，which lives on the sea floor，uses its poisonous tentacles (触须) to stab passing creatures with a kind of poison—making them helpless and fit to be eaten.

    The surgeonfish (刺尾鱼) is an attractive reef fish that is poisonous. Scientists believe that the world's seas hold some 1, 200 different surgeonfish species and think that they injure about

    50，000 people per year. But the surgeonfish poison can also bring great benefit—they are useful in the development of new drugs.

    What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any especially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

    Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

    Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

    Believe it or not, we all have an inner-child living inside of us. One of the greatest problems is people's desire to silence the inner-child. Instead, welcoming this voice to the conversation can be very beneficial and help you in many areas of your life.

    Why is it so important to listen to your inner child?

    Do you remember you wanted to be an adult more than anything else when you were young? But now you're an adult, and do you ever find yourself thinking, "I wish I were a kid again?" That's where your inner-child comes in. That's the voice inside of you telling you to have fun, be silly and let loose. Adult life is full of important responsibilities, but once in a while you just have to let go and have fun like a child. It's healthy and good for the soul to not take things so seriously all the time.

    We can tell bad choices and mistakes of the past, but unless you help your inner-child heal and recover, planning for the future will always be difficult. The inner-child will relive these painful experiences until you learn to accept them, forgive and let go. We must show love and acceptance to our inner-child, as this is the only way to heal, move on and not continue to suffer from the pain of these unpleasant times. This is the opportunity to go back in time and let you know just how wonderful, beautiful and special you truly are.

    One of the most common times your inner-child is likely to appear is when you're facing a decision you are unsure about. Naturally, when we were children, doubt and uncertainty scared many of us. So, it's no surprise that when faced with these moments as adults, the inner-child decides to show up. Don't let this scare you; instead, listen to that voice as it is trying to guide you in the decision-making process. Ask it questions, speak with it.

    When you can start to see your inner-child as your partner who helps guide you through this crazy life, it's amazing what can happen. Don't fight it. Go with it and see how it changes your life for the better.
