Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined .Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.

    Nitrogen（氮） and carbon are shared through miles of underground fungi（真菌） networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons（神经元）in our brains, and when one tree is destroyed, it affects all.

    Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend .She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow .When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

    “We didn't take any notice of it .” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    A culture's values can be mirrored by its humor. Humor has been evaluated by many great minds such as Thomas Hobbes, who, In"On Nature", disliked humor," Laughter is nothing else but sudden glory arising from sudden thought of feeling far better than others." He thought humor to be a negative quality of human narrow-mindedness.

    However, Mordechai Gordon, PhD of Education, insists," Humor allows us to view the world from an angle that is amusing rather than serious." I agree with Gordon. Learning to look at the world through humor is important.

    In the United States, every four years an election occurs. Without humor as a way to express their feelings, how would Americans be willing to support the election? Television shows like "The Daily Show" have become important parts of American culture. They are mothering the masses by unconsciously inputting politics into our mouths. They make politics fun.

    Of course, politics is only one type of humor. Social humor helps people through the twists and turns of the human condition. American pop culture promotes an unhealthy self image. On the topic of self-image, Hari Kondabolu stands out. He has a joke about the popular musical group "The Pussycat Dolls", describing their hit song "Don't Cha" as a negative representation of women. He points out an obvious offence in American culture.

    A study from Loyola University of Maryland has shown that humor is one determining factor for selecting a mating partner. Amongst other things, mates look for an outstanding funny bone in a potential partner.

    Of course, humor is not always used for good purposes. Humor can be linked to vulgarity（粗俗）and racism, but, like everything else, it has potential to unite human beings by allowing us to laugh at ourselves, our failures and our connection with one another.

    Though life may seem tough and depressing at times, all I have to do is look in the mirror at my increased wrinkles（皱纹）to know that there is a comedy out there that even Chaplin wasn't aware of.

    With that in mind, remember to laugh with humanity and sometimes at humanity.

    Regardless of how far we'd like to believe gender(性别) equality in the workplace has come, there's still a yawning gap between male and female leaders in the professional world. A 2018 statistic shows that women nowadays hold just 5.8 percent of CEOs positions at S&P 500 companies, according to Catalyst.

    While it's not a huge shock that women are somewhat underrepresented in leadership positions, what is surprising though, is the fact that females may actually be better suited to lead in almost every area, at least according to new findings from the BI Norwegian Business School.

    In their research，Professor yvind L. Martinsen and Professor Lars Glas surveyed (调查)2,900 managers with a special focus on personality types. The results were clear: Women scored higher than men in four of the five major leadership-centric categories.

    While some people believe that men inherently make better leaders — probably because they picture a leader with a commanding voice, which is more typical of men than women — this piece of research suggests that women are better at methodical management and goal-setting, openness, sociability and supportiveness, as well as ability to communicate clearly.

    There was one area in which men scored higher than women, though, and that was on emotional stability and ability to face job-related pressure and stress. The results suggest that women are more sensitive to the effects of high-pressure or highly emotional situations.

    Obviously，it's important to consider individual(个人的) differences. Anyone, regardless of gender, may be an inspiring leader and a competent boss. But next time you're hiring for a management position, you just might want to give the resumes(简历) from female candidates a harder look.

    Our society is generally becoming one of giant enterprises directed by a bureaucratic management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, Nell-ventilated factories and piped music, and by psychologists and "human-relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he is bored with it. In fact, the blue and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management.

    The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction of interesting life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings.

    Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the right mixture of obedience and independence. From the moment on they are tested again and again—by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one's fellow competitor creates constant anxiety and stress, the very causes of unhappiness and illness.

    Am I suggesting that we should return to the preindustrial mode of production or to nineteenth-century "free enterprise" capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social system form a bureaucratically managed industrialism in which maximal production and consumption ends in a humanist industrialism in which man and full development of his potentialities – those of all love and of reason—are the aims of social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.

    Facebook is an American online social media and social networking service. The Facebook website was launched on February 4, 2004, by Mark Zuckerberg, along with fellow Harvard College students and roommates.

    The founders had limited the website's membership to Harvard students at first; however, later they expanded it to various other universities, and eventually to high school students as well. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered (注册了的) user of Facebook, though differences exist in the youngest age requirement, depending on local laws. Facebook has more than 2 billion monthly active users as of June 2017. As of April 2016, Facebook was the most popular social networking site in the world, based on the number of active user accounts.

    Facebook may be accessed by a large range of desktops, smartphones over the Internet and mobile networks. After registering to use the site, users can create a user profile (简介) showing their names and so on. Users can add other users as "friends", exchange messages, post photos and so on.

    Facebook makes most of its income from advertisements which appear on screen, marketing access for its customers to its users.
