    It was hard to accept, but the sad day had finally arrived. I still remember the tears welling up in my six-year-old sister's eyes as she looked around the empty closet in wonder. The space once filled with her clothes now held only loneliness and sorrow. This little child had come to the realization that her father was gone. He had left us, and there was simply no way to change it.

    Being the oldest of four girls has never been easy, but with the departure of our father, our world and dreams were broken beyond repair. My mother, the most amazingly warm-hearted person in the world, has worked harder than anyone should simply to mend our broken household. However, long hours at work often prevented her from physically being there in our times of need. This is where I have stepped up as the temporary caretaker of my three small sisters.

    Many students write college essays about their leadership positions in school and the community but I feel that my greatest accomplishment is the role I have played within my own family.

    Senior year in high school is not simple for anyone, especially when it feels like the entire world is resting on your shoulders, but this is how I have felt for the past two years, I have continually tried to fulfill the dream my mother holds for my future. My mother was not able to complete her college education, and so this success is her top significance for her children.

    A leader is defined as one who has influence on others. I hope that my leadership affects the lives of my sisters and everyone around me. In dedicating myself to my family and school, I have set goals that I will do anything to accomplish. I am an extremely determined individual, and my university will help me take the next step in climbing the ladder of success.

    A new app aims to help parents interpret what their baby wants based on the sound of their cry. The free app Chatter Baby, which was released last month, analyzes the acoustic (声学的) features of a baby's cry, to help parents understand whether their child might be hungry, fussy or in pain. While critics say caregivers should not rely too much on their smartphone, others say it's a helpful tool for new or tired parents.

    Ariana Anderson, a mother of four, developed the app. She originally designed the technology to help deaf parents better understand why their baby was upset, but soon realized it could be a helpful tool for all new parents.

    To build a database, Anderson and her team uploaded 2,000 audio samples of infant(婴儿) cries. She used cries recorded during ear piercings and vaccinations to distinguish pain cries. And to create a baseline for the other two categories, a group of moms had to agree on whether the cry was either hungry or fussy.

    Anderson's team continues to collect data and hopes to make the app more accurate by asking parents to get specific about what certain sounds mean.

    Pediatrician Eric Ball pointed out that evaluating cries can never be an exact science. “I think that all of the apps and technology that new parents are using now can be helpful but need to be taken seriously,” Ball said ,“ I do worry that some parents will get stuck in big data and turn their parenting into basically a spreadsheet(电子表格) which I think will take away the love and caring that parents are supposed to be providing for the children. ”

    But Anderson said the aim of the app is to have parents interpret the results, not to provide a yes or no answer. The Bells, a couple using this app, say it's a win-win. They believe they are not only helping their baby now but potentially others in the future.

    It's a real case of fish out of water. Blennies (鲇鱼) in the South Pacific Ocean are gradually relocating to land to escape their predators (捕食者), in an example of evolution in action.

    Fish first began crawling onto dry land about 400 million years ago, kicking off an evolutionary chain of events that led to humans. But their reasons for exiting the sea have been uncertain.

    To look for clues, Terry Ord at the University of New South Wales in Australia has been studying several species of blennies at Rarotonga, the largest of the Cook Islands.

    At low tide, blennies are commonly found swimming in rock pools around the edges of the island. But when high tide moves in, they climb up to dry land and move around the rocks until the tide retreats.

    The researchers found that this is most likely to avoid predators that swim in with the rising tide – mainly bigger fish like lionfish.

    To test what would happen if blennies did not have an escape plan, they made blenny models and sank them in the sea. The mimics ended up with wounds, bite marks and chunks-missing.

    Of course, there are still dangers for blennies on land, like the occasional bird attack, but the predation risk on land is a third that of underwater.

    What's more, moving onto land has additional benefits for blennies. Holes in the rocks provide sheltered nests for laying eggs, and they can maintain their diet of bacteria.

    In fact, several species of blenny fish at Rarotonga have already made the full transition to land-dwelling (陆生的) species. They continue to breathe with their gills, but have developed stronger tail fins and jump from rock to rock.

    Ord believes that many evolutionary processes have been driven by the need to escape predators. “It is often assumed that animals move homes to find new sources of food, but in many cases, escaping predators is a stronger motivation.” he says.

Five steps to make a difference to the oceans

    The oceans are being seriously polluted now. Plastics are harming the marine (海产的) life. Carbon pollution is warming the oceans and increasing their acidity(酸度). Waters are being overfished.        Here are some steps we can take to help make a difference.

    ⒈Bring our own bags.        Try carrying a reusable bag at all times, including while traveling, and bringing our own things to work to avoid relying on plastic items.

    ⒉Talk about it now. We should carry that conversation into public places. Talk to our friends and family about why the ocean is important and why we take steps to help it, and challenge them to do the same.

    ⒊       A good way to make a difference is to organize a garbage cleanup now. Whether it's an inland cleanup or one near the coast, plan one in our community.

    ⒋Throw away our cars.        When we hang out, we should reduce our carbon footprint, which may help slow global warming and ocean acidification as well as conserve energy

    ⒌Recycle, obviously. Experts say recycling is an obvious action to take. Check on what can be recycled in our community, and make sure you're separating out your plastic.

    In summary, think about it more and act on it more. The more someone thinks about plastics and plastics pollution, the environment and the consequences of our actions, the more likely they are to act on it.       

A. Plan a cleanup.

B. Choose public transportation over driving our cars.

C. Driving cars is not a good way to protect the oceans.

D. However, experts say there's still hope to make a difference.

E. However, marine life plays a very important role in the oceans.

F. If everyone can contribute to the oceans, the oceans will be well preserved.

G. Whenever we put something, we should bring our own bag, but not a plastic one.

    In kindergarten, I met my first love – dancing. For the last eleven years, I have spent many hours at the dance studio. The 1 I began as a little girl has shaped my personality, forming 2 that I will have for the rest of my life.

    Once while our dance team 3 for the state competition, six senior members quit without notice, leaving our team without a 4. My team's enthusiasm for the season was cut in half. 5, I was determined to become the new captain and lead my team past this obstacle.

    During the first practice after the seniors quit, my team's emotion was 6. As a leader, I tried to motivate my team through 7. I started to do 8 work outside practice to improve my kicking technique. My team respected me as a coach because I showed 9. On weekends, I spent hours trying to make up a creative competition routine. I wanted my team members to 10 the dance and perform well.

    Before the state meet, I drilled the 11 into the girls' heads and constantly encouraged them to work harder. I would shout out names of people who were 12 well during the dance, and the girls would 13 with even more energy. Through my dance experience, I also found I got better by 14 myself. I mixed new skills into the routine for the state competition to 15 my team's technique. We wanted to prove to ourselves and our school that we could still be a(n) 16 dance team without the girls who 17.

    On the stage, I felt my team's 18. I was proud that we were able to rebuild our confidence and go beyond our expectations at the state competition. We were 19 for all our hard work by placing in the top five. This experience taught me a lesson: with a passion for something, I could 20 any obstacle with creativity and determination.

    Today, when I walked to home after school, I found the sunset was very beautifully. I stopped at the park and sit on a bench to appreciate the scenery. There was so many people at the park, most of whom were old couples, but they went for a walk. There was a special couple walk hand in hand, which caught my attention. The old woman couldn't walk well because there was something wrong with her right legs. The old man took care of them carefully. They set good example to the young couples, showing that true love is. Against the sunset, they made up a beautiful scene.
