When I started teaching at school, I was sure I would change the world and touch children who needed love.

    Although my students seemed to respond pretty well to my teaching , there was a small group of girls who became more and more hostile towards me.

    One day a fight happened in my classroom. Trying to end it, I stepped in to face one of these hostile young women, who started hitting me in the face. Two boys jumped up to control the girl, but the damage was done.

    While the girl was suspended for a few days, I was determined that she would not return to my classroom. But I also prayed. I wanted to see all the students right there in my daily work at school.

    On the top of my daily lesson-plan book, I wrote this statement, “To see all the children in my classroom is always beautiful.” With this view I could expect to heal any anger towards the girl in my heart.

    After her suspension, she returned to my classroom. The student's young mother was trying to raise six children while her husband was away in the war. The mother and I agreed to work together to help her oldest daughter.

    There were no more incidents of anger the rest of the year. In fact, in the seven years I remained at that school, I taught all six of this family's children. When the youngest was in my class, the mother told me, “Our family love you. Every year one of my kids says, ‘I hope I'm in her class!'”

    The standard of seeing each of my students as a perfect one was the best teaching tool I had, and led to success.

    When men get together, they seldom talk about their feelings or inner thoughts. However, they talk about a lot, like their newest computer, how to repair their car, or even business.

    Talk might move to the best place to find fish or women, jump to computer games, then continue to the sport of the season. They also like to tell jokes each other and spend a fair amount of time playing one-up and boasting (吹牛). Men seldom call each other to chat.

    When man meets woman, he usually wants to make a good impression. Many single men try hard to carry on amusing, fun, and pleasant conversations. They use conversation to discover her interests and feelings in order to learn how to be attractive to her.

    Some men, either out of nervousness or ignorance, spend most of the time talking about themselves, often appearing to show off their achievements or talk endlessly about their problems or work. Even the quietest man talks to his woman when love is new.

    When women get together, they talk about feelings and relationships, their work and their family. They enjoy talking but also want the give and take of talk, then listen. Women often call each other to chat. Conversation is an important part of most women's lives.

    As relationships progress, however, many a man turns on the television and forgets how to talk. This raises anger and cry from his woman partner who says, “You never talk to me anymore.” Some men start talking. Many, however, mainly discuss their own achievements and problems.

    When the woman starts talking about her favorite subjects: feelings, family, relationships, friends and her work, many men lose interest or bring the conversation back to themselves. Pretty soon, the man is back to staring at the television each night, wondering where his relationship has gone. The woman is talking to her friends, mom, sister, or neighbor, often about that very relationship and how she is hurting.

    There are two kinds of secrets: secrets of nature and secrets about people. Natural secrets exist all around us; to find them, one must study some undiscovered aspect of the physical world. Secrets about people are different: they are things that people don't know about themselves or things they hide because they don't want others to know. So when thinking about what kind of company to build, there are two distinct questions to ask: What secrets is nature not telling you? What secrets are people not telling you?

    It's easy to assume that natural secrets are the most important: the people who look for them can sound authoritative (权威的).This is why physics PhDs are difficult to work with—because they know the most basic truths, they think they know all truths. But does understanding electronic theory automatically make you a great marriage counselor? Does a gravity theorist know more about your business than you do? At PayPal, I once interviewed a physics PhD for an engineering job. Halfway through my first question, he shouted, "Stop! I already know what you're going to ask!" But he was wrong. It was the easiest no-hire decision I've ever made. Secrets about people are relatively overlooked. Maybe that's because you don^'t need a dozen years of higher education to ask the questions that uncover them: What are people not allowed to talk about? What is forbidden or taboo?

    The best place to look for secrets is where no one else is looking. Most people think only in terms of what they've been taught; schooling itself aims to spread basic wisdom. So you might ask: are there any fields that matter but haven't been standardized? Physics, for example, is a real major at all major universities, and it's set in its ways. The opposite of physics might be astrology, but astrology doesn't matter. What about something like nutrition? Nutrition matters for everybody, but you can't major in it at Harvard. Most top scientists go into other fields. Most of the big studies were done 30 or 40 years ago, and most are seriously flawed (有缺陷的). The food pyramid that told us to eat low fat and large amounts of grains was probably produced by Big Food(美国著名食品公司)than real science; its chief impact has been to worsen our obesity(肥胖)problem. There^'s plenty more to learn: we know more about the physics of far away stars than we know about human nutrition. It won't be easy, but it's not obviously impossible: exactly the kind of field that could produce secrets.

In the past decade ocean oxygen levels have taken a dive — an alarming trend that is linked to climate change, says Andreas Oschlies, an oceanographer at the Helmholtz Center for Ocean Research in Germany, whose team tracks ocean oxygen levels worldwide. "We were surprised by the intensity of the changes we saw, how rapidly oxygen is going down in the ocean and how large the effects on marine ecosystems are," he says. It is no surprise to scientists that warming oceans are losing oxygen, but the scale of the drop calls for urgent attention. Oxygen levels in some tropical regions have dropped by an astonishing 40 percent in the last 50 years, some recent studies reveal. Levels have dropped less significantly elsewhere, with an average loss of 2 percent globally.

A warming ocean loses oxygen for two reasons; First, the warmer a liquid becomes, the less gas it can hold. That is why carbonated drinks(碳酸饮料) go flat faster when left in the sun. Second, as polar sea ice melts, it forms a layer of water above colder, more salty sea waters. This process creates a sort of lid that can keep currents from mixing surface water down to deeper depths. And because all oxygen enters the surface, less mixing means less of it at depth.

Ocean animals large and small, however, respond to even slight changes in oxygen by seeking refuge(避难所) in higher oxygen zones or by adjusting behavior, Oschlies and others in his field have found. These adjustments can expose animals to new predators or force them into food-scarce regions. Climate change already poses serious problems for marine life, such as ocean acidification, but deoxygenation is the most pressing issue facing sea animals today, Oschlies says. After all, he says, "they all have to breathe."

Aside from food web problems, animals face various other physiological challenges as their bodies adjust to lower oxygen levels. Chinese shrimp(虾) move their tails less vigorously to preserve energy in lower oxygen environments. Some creatures, such as jellyfishes, are more tolerant of low oxygen than others are. But all animals will feel the impact of deoxygenation because they all have evolved their oxygen capacity for a reason, says Oschlies. "Any drop in oxygen is going to damage survivability and performance," he says.

After moving to the United States in 1901, 19-year-old Bob Douglas found a job as a doorman in New York. Later, a co-worker took him to visit a basketball court, and he was amazed by the athletic prowess on display. At that moment, Douglas, who had enjoyed playing sports as a child, was determined to create a basketball team and provide greater opportunities for New York City's Black athletes. 

He needed to find a place for his team to play. When asking a ballroom owner, William Roach, for permission to use one of the dance floors, Douglas was replied with "you guys will break up my place". After promising to take on all the financial risk, he finally persuaded Roach to change his mind and called the team "Rens". 

However, their ballroom had fewer seats and attracted fewer people than others, so Douglas had to pack the house to generate profits and keep his team alive. They traveled the country playing any opponent that would agree to schedule them, during which they repeatedly faced discrimination and unfair treatment and the players were often banned from hotels and restaurants. 

No matter the obstacle, the Rens just kept strict practicing. They helped change the game of basketball by focusing on quick passing, which let the players move faster, play a more fluid (流畅) game and keep winning. In 1925, the Rens shocked the world by defeating the Original Celtics, the most dominant team of their day. During the 1932-33 season, the team won 88 straight games, a professional basketball record that remains unbroken. 

Unfortunately, the Rens disbanded (解散) in 1949. But in time, they were recognized for the important role they played in advancing Black athletes in basketball, ensuring that although the Rens aren't a household name, their story will never be forgotten.

How Did Poetry Begin?

Poems can make you feel emotions, like anger or sadness, depending on the words and how they are put together. That is the 1 of poetry. 

Poetry 2 even before humans knew how to read and write, dating back to around 3000 BCE. Some of the earliest poetry was 

3 or sung, and was used as a way to record and pass down historical and religious stories and cultural traditions from one generation to the next. Since writing was not practised then, certain sounds and rhymes were used to make these stories 4 and therefore, memorable. 

There are 5 three types of ancient poetry. The first was an epic(史诗) or long narrative(叙事的) poetry usually about a 6

event. The second type was lyric(抒情的) poetry or poetry that 7

personal feelings. Finally there was drama or stories written in verse and usually 8 like Greek tragedies and Shakespeare's plays. 

The invention of the printing press(印刷机) in the 15th century brought poetry to the common people. This was followed by several major literary periods, during which poetry 9 dramatic changes. They started with Europe's Renaissance period from the 14th to the 16th century, which first helped poetry and poets like Shakespeare and Sir Walter Raleigh become popular. 

The Romantic period saw 10 poems that expressed a poet's joys, hopes, and sorrows in a conversational tone. Then came the Victorian era, which saw the 11 of structured poems and the birth of modern "12 verse" poetry. American poet Walt Whitman's Leaves of Grass is 13 to be the first example of free verse poetry. 

Modern poetry is a 14 of all of these styles. We still see rhymes in children's poems and in the popular African-American styles of hip hop and rap music, which are a 15 of rhymed poetry put to a musical beat.
