With the completion of the Human Genome（基因组）Project more than 20 years ago, and the discovery of the double helix structure of DNA enjoying its 70th birthday last year, you might assume that we know how life works. Think again!

Evolution has a 4bn-year head start on us. However, several aspects of the standard picture of how life works-the idea of the genome as a blueprint, of genes as instructions for building an organism, of proteins as precisely tailored molecular（分子）machines and more-have wildly reduced the complexity of life. 

In the excellent book How Life Works, Philip Ball explorers the new biology, revealing life to be a far richer, more delicate affair than we have understood. Ball explains that life is a system of many levels-genes, proteins, cells, tissues, and body modules-each with its own rules and principles, so there is no unique place to look for an answer to it. 

Also, How Life Works is a much more appealing title than the overused question of "What is life?". We should be less concerned with what a thing is, and rather more focused on what a thing does. Defining a living thing implies an unchangeable ideal type, but this will run counter to the Darwinian principle that living things are four-dimensional, ever changing in time as well as space.

But it's an idea that is deeply rooted within our culture. Ball points out that we rely on metaphors（比喻）to explain and explore the complexities of life, but none suffice. We are taught that cells are machines, though no machine we have invented behaves like the simplest cell; that DNA is a code or a blueprint, though it is neither; that the brain is a computer, though no computer behaves like a brain at all.

Ball is a terrific writer, pumping out books on incredibly diverse subjects. There's a wealth of well-researched information in here, and some details that are a bit chewy for the lay reader. But the book serves as an essential introduction on our never-ending quest to understand life.

In Rio, soccer was not only a sport but also a lifestyle. Lamine's flashy1 and exciting gameplay were the drive to his success. He was in a team called FC that had the best players.

As FC made it to the soccer final,2 filled the air. They were against their biggest rivals KD. As the clock counted down, one of Lamine's teammates3 the ball over to Lamine.

With a powerful4 , Lamine aimed for the goal, the ball soaring（呼啸） through the air. Time seemed to stop as the goalkeeper leaped5 . Luck was not at Lamine's side as the ball was cleared by the defender. The referee's whistle blew,6 the game.

With the sun setting, Lamine's father found him sitting7 on the field. Father was once a skilled soccer player, knowing the8 that came with the game. He patted Lamine on the back, "Lamine, even the greatest players would9 chances. Don't let one setback define you. "

Encouraged by father's words, Lamine10 and hugged him. For the next few days, they spent mornings and evenings on the field,11 his shots and improving his speed and skills.

The next game arrived, and Laminez found himself in a12 position. This time, with a swift move, he dribbled past defenders and13 the ball into the net.

The crowd erupted in cheers, and Lamine's teammates14 him carrying him to the sidelines to celebrate. Lamine went to hug his dad tightly. "I'm proud of you, son. I'll15 you my signature move in my old days. "his father said.

In spite of the fact that I had stayed with my sister for 14 years. I knew one thing—I would not want to be like her. In high school, she was a journalist and it was 1 she talked about. No matter how many times I said it, I 2 myself in "Intro to Journalism" freshman year,3 . Why? That was because my mother wanted me to be a journalist, 

Though it was the4 thing I wanted to do, I got to realize the point of being a journalist. It was 5 writing a report. It was also communicating with people by telling stories. After a short term, I began to see what happened around me 6 —I saw things as7 , which I wanted to share with people who wants to 8 .

In the second semester, I joined the newspaper staff and 9 nearly every position on staff, from designing different columns to taking photographs. I wrote stories, opinions, and almost any other thing for every 10 of the paper.

I loved everything around me, but I found my gift in visual journalism. I had a/an 11 for design and I was12 ready to put in. When I was writing each story, I promised to tell in its entirety. There is possibility that some 13 of a story can't be presented in a paragraph form. That is 14 I came in. I worked to improve the 15 of our magazine every day. But my work is not 16 to this. I also worked to add the web and multimedia 17 the publication. I loved producing content for the newspaper. 18 , I found myself creating less and less through my junior year. Then 1 was thinking up ideas and helping others to do the 19 to make their work happen.

Now, I'm proud to say that I have fully made 20 of what it means to be a good storyteller.

My cousin and I took a trip by rail across Canada from west to east. Before starting out, we spent a couple of days in Vancouver, admiring the {#blank#}1{#/blank#} (sight). Then we arose early to take the train to Lake Louise, passing through the Canadian Rockies. {#blank#}2{#/blank#} (see) from the train window, the mountains and forests looked {#blank#}3{#/blank#} (mass). We spent the night near the lake, where the blue water literally took our breath away, {#blank#}4{#/blank#} headed to Jasper the next morning. The beautiful scenery convinced us it was the most awesome journey we {#blank#}5{#/blank#} (take). From Jasper, we boarded the train bound {#blank#}6{#/blank#} Toronto. One of our first stops was in Edmonton, which {#blank#}7{#/blank#} (be) home to many shopping malls. We never anticipated seeing such an open country until the train headed across the Great Prairie. {#blank#}8{#/blank#} amazed us most were a bunch of farms covering two wheat-growing provinces. The train thundered on, through the {#blank#}9{#/blank#} (roll) hills in Ontario. It was {#blank#}10{#/blank#} (true) enjoyable to watch the red maple leaves outside the window. After four days, we reached Toronto.

It was a typical weekend for Mitch White and his friends. They were out celebrating a bachelor party, sailing the peaceful waters of the Minnesota River. They never expected that this single party would transform from a relaxed canoe trip into a painful rescue mission. With the sun setting, an unexpected bark changed everything.

Led by Mitch White, the soon-to-be-married man, they searched for the source of the sound along the banks of the river. Suddenly, a weak cry for help came from the mud. They were surprised to find that the head of a 13-year-old St. Bernard named Ed was barely visible in the thick mud. Mitch said, "The dog wasn't moving on its own, so we should feed it and give it water. " The dog looked like i had used all its strength.

The men took up their oars（桨） and began digging, their festive mood giving way to a focused rescue mission. It took them more than half an hour to free the trapped dog as it was already breathing very feebly after possibly being trapped for 24 hours. When they got the poor fellow out of the mud, he couldn't walk, so they carried him back to the house. Back home with his owner, George Niskanen, Ed began his slow restoration-a happy ending to a dangerous adventure. George was thankful to the bachelor party heroes.

Now, the people of Carver, Minnesota, have new heroes to cheer for. Indeed, this incredible act of bravery and compassion redefined the meaning of a bachelor party. It became a heroic tale of humanity, friendship, and the instinct（本能）to do what's right.

The Beauty of Creative Friendships

I recently walked through an incredible exhibition in Venice. It 1 about 75 art works that a Dutch-American artist created during the time he spent in Italy in 1959 and 1969. The pieces on show included his ink-on-paper drawings, some gestural drawings, landscapes and sculptures.

Born in 1904, de Kooning spent the majority of his artistic career as a (n) 2 but in 1969, while visiting Rome, he 3 an old friend, the sculptor Herzl Emanuel, who invited him to his studio and 4 him to try working with 5 .

At age 65, de Kooning 6 his first sculptural works, 13 small clay items. It was the 7 of a new artistic era for him and, over the next 15 years, sculpture became a (n) 8 and inseparable part of his career.

Later, after I left the exhibition, I was 9 by how beautiful it was that de Kooning began making sculpture because of the initial 10 and encouragement of his 11 . It got me thinking about the often unacknowledged role that some friendships play in the creative process of 12 across all types.

We often think about those friendships that journey deeply with us in our private lives, 13 us through emotional ups and downs. But friendships that develop our professional selves are also 14 .In offering courage, insight and clarity on the work that we produce, these friendships 15 the overall quality of our lives.
