I look in the mirror, and I'm not happy with what I see. I don't have a "perfect" face. I look in the magazines and all I see are girls with fair hair, blue eyes, and, of course, a pretty little nose. They're on the outside of the buses that I take home, the television programs I watch, and the billboards（广告牌） I walk under. Almost every advertisement I see shows this human physical "perfection". These billboards not only tell me what to drink, but also how to look.

    Our society place more importance on a person's physical beauty, rather than their ability, honesty and character. We have influenced women to go through painful surgeries（手术）and starve themselves to become this society built physical model. To be a beautiful woman in the 21st century doesn't mean that you are a brilliant doctor or caring mother. It means you have the perfect jaw, eyes and lips. It means that you can be six feet tall and weigh one hundred and ten pounds.

But what about the women who are starting to leave their youth? Instead of looking at aging as a sign of wisdom, we try to prevent the aging process(过程）. It's a kind of funny thing to want to look eighteen when fifty. Fifty is a relaxed age, when you can step back and look at all you've achieved (successfully complete something). It is when your hard work pays off. Unfortunately, our society just sees you as "old". To stop the aging process, women buy wrinkle（皱纹） creams, do eye lifts and face lifts. They spend thousands of dollars to win the hopeless battle against age.

    I remember when I was about thirteen years old and going through teens, I had oily hair, and a half developed body. I hated the way I looked. I used to cry to my mother all the time, but she would just laugh and tell me that "you don't want anyone to like your appearance. It's your heart that is important, because beauty fades.（消逝）" I knew that she was right. If you work on your heart enough, people will start to see the beauty in you, which lasts and remains on even after you die.

    We all fail,all the time.We might miss a call with a client because of an emergency work meeting,or miss that meeting because another project has suddenly become urgent.And then we (or our families) get sick,and we have to shift priorities around again.

    These unsystematic failures are benign,though.They reflect that all of us have limited resources.There simply is not enough time,energy,or money,to do everything you want to do all the time.Part of being a responsible adult is learning to make trade offs: balancing your conflicting goals and trying to get as much done as you can in the time you have.

    The thing you really need to watch out for is the systematic failure.The systematic failure happens when there's a particular goal you want to achieve,but never get to.The causes of systematic failures usually boil down to some combination of these three factors:

    1).Short-term pressures versus long-term goals.Most of us prefer to achieve pressing short-term goals rather than put time into long-term projects.Lots of research suggests that our brains are wired to prefer tasks that pay off in the short term rather than those whose benefit is long-term.The people who do manage to accomplish their long-term goals create regular space to make progress on them.

    2)._________Without even realizing it,we often do what is easiest to accomplish rather than what we say is most important.Email is a great example.If you are like most people,you keep your email program open at work all day. Consequently,each new message is an invitation to drop what you are working on to check it.It feels like work and it's much easier than finishing that 100-slide presentation.Simply shutting off email for a few hours a day can remove this source of distraction from the environment.

    3).Working for too long.Many workplaces create pressure to stay at the office for more and more hours,which (paradoxically) creates opportunities for systematic failures.Work is not an iron man competition where the last person there wins.Most people have an optimal（最佳的）number of hours they can work each day.For example,I can be productive at work for about 8-9 hours a day.If I spend any more time at work than that,then at some point,I start doing "fake work."

    The next time you run into trouble,assess whether it's an unsystematic failure or a systematic one.When you notice a systematic failure in your life,you need to make a change in your behavior.If you don't make a change,you will continue to fail.

    Finally,if you experience a lot of unsystematic failures,it might be worth rethinking the number of tasks you are taking on.Perhaps you need to offload some responsibilities onto someone else,before you start experiencing more systematic failures.

    The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world's ecological balance.

    On a local level, the damage of the forest required by full-sun fields affects the area's birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees' flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.

    On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.

    Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.

    It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.

    The phone ID flashed “Emergency Vet”. “Oh no” I whispered. I could not lose Merlin now.

    Ron and I had tried to have children for a long time with depressing results. I threw myself into my work. Any maternal feelings I had were spent on Merlin.

    I couldn't wait to get home from work each night. I wanted to pick up that warm bundle of loving fur and nestle him. I wanted to sing “Rock-a-bye Merlin” as I did every night as he would put his paws around my neck.

    Merlin was my comfort especially at times when I wondered if God was listening. But last night something had changed. Not only did I sing “Rock-a-Bye Merlin” but I asked “What will I do after you're gone?”

    Although Merlin was 19 years old a senior in the age of a cat he didn't look or act that way. I didn't want to accept the fact that he was nearing the end of his lifetime. My job at the law firm was so demanding and stressful that I couldn't imagine getting through the day without Merlin waiting to greet me at home.

    I dialed the vet's number. I asked for my husband but he already left. Then I took a breath and asked the question that no one wants to ask “Is my Merlin still alive?” The nurse said “yes.”

    Ron came home and said that Merlin had almost no red blood cells left. White blood cells were replacing them. Merlin would need expensive transfusions most likely on a monthly basis. We both knew Merlin was running out of time. I asked Ron to drive me to the vet so I could say goodbye to my little boy cat but he was beat tired and it was late. Ron said if Merlin was still alive the next morning then he would take me to the vet.

    The next morning I called the vet. Merlin had survived the night.

    After driving to the vet I went into the examining room. The nurse brought Merlin and placed him on an examining table on his side. His eyes were tightly shut. I thought he died already. I carefully edged my hand to reach his body. His body felt warm but when I spoke his name there was no response. No response to his name or that I was there and that I loved him. I was extremely sad.

    In that examining room I felt helpless. I wondered how many people in an examining room felt as helpless as I did.

    Feeling driven to prayer I yelled “God this isn't good enough. I need to see my Merlin the way I remember him I need a miracle and I need it now!”

    At that moment God granted a miracle. Merlin's favorite compliment entered my mind. I said “Merlin You are Beautiful and You are Gorgeous do you hear me?” One eye opened.

    I said “Gotcha”. I kept repeating those words.

    Merlin opened the other eye and one limb at a time got up. He was waiting for that phrase. He wanted to hear that he was beautiful and gorgeous again.

    Then I experienced another miracle.

    There was no sound in that examining room until Merlin started walking to me. From out of nowhere or maybe from heaven I clearly heard a song we sung in church often: “It Is Well With My Soul.” I remembered thinking “Yes it is well with my Soul. I got to see my little boy cat one more time.”

    Merlin walked to me. He put his face in mine which he had never done before. He rubbed a circle around my face twice. Merlin said goodbye with his face and marked me for life.

    Ron appeared shocked that Merlin was up and had walked to me. I said to Merlin “Tell God you are a good boy and how much we love you” and then handed him back to the nurse.

    Tears of gratitude poured forth in memory of a miracle. You see for nineteen years God spoke to me through a special cat named “Merlin.” On Merlin's last day God proved he heard me when he granted a miracle. That miracle gave me time to say goodbye.

    Even plant can run a fever, especially when they're under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away straight up. A decade ago, adopting the infrared（红外线） scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely（精确的） target pesticide（杀虫剂） spraying rather than rain poison on a whole field, which always includes plants that don't have pest problems.

    Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Fixed on a plane flown at 3,000 feet at night, an infrared scanner measured the heat sent out by crops. The data were transformed into a color﹣coded map showing where plants were running "fevers". Farmers could then spot﹣spray, using 50 to 70 percent less pesticide that they otherwise would.

    The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long﹣term supporters were hard to find. But with the renewed concern about pesticides on produce and refinements（改进） in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt that the technology works. "This technique can be used on 75 percent of agricultural land in the United States," says George Oerther of Texas A&M, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial support which he failed to obtain 10years ago.

    According to official government figures, there are more than twice as many kangaroos as people in Australia, and many Australians consider them pests(有害动物). Landholding farmers say that the country's estimated 50 million kangaroos damage their crops and compete with livestock for scarce resources. Australia's insurance industry says that kangaroos are involved in more than 80 percent of the 20,000-plus vehicle-animal collisions reported each year. In the country's underpopulated region, the common belief is that kangaroo numbers have swollen to “plague proportions."

    In the absence of traditional hunters, the thinking goes, killing kangaroos is critical to balancing the ecology and boosting the rural economy. A government-sanctioned(政府认可的) industry, based on the commercial harvest of kangaroo meat and hides, exported $29 million in products in 2017 and supports about 4,000 jobs. Today meat, hides, and leather from kangaroos have been exported to 56 countries. Global brands such as Nike, Puma, and Adidas buy strong, supple “k-leather" to make athletic gear. And kangaroo meat is finding its way into more and more grocery stores.

    Advocates point out that low-fat, high-protein kangaroo meat comes from an animal more environmentally friendly than greenhouse gas-emitting sheep and cattle. John Kelly, former executive director of the Kangaroo Industry Association of Australia, says, “Harvesting our food and fibers from animals adapted to Australia's fragile rangelands is extremely wise and sustainable. Many ecologists will tell you that there is no more humane way of producing red meat."

    Opponents(反对者) of the industry call the killing inhumane, unsustainable, and unnecessary. Population estimates are highly debatable, they say, but “plague proportions" are biologically implausible. Little kangaroos grow slowly, and many die, so kangaroo populations can expand by only 10 to 15 percent a year, and then only under the best of circumstances. Dwayne Bannon-Harrison, a member of the Yuin people of New South Wales, says the idea that kangaroos are destroying the country is laughable. “They've been walking this land a lot longer than people have," he says. “How could something that's been here for thousands of years be 'destroying' the country? I don't understand the logic in that."

    Can Australians' conflicting attitudes toward kangaroos be reconciled(和解)? George Wilson says that if kangaroos were privately owned, then graziers(放牧人)—working independently or through wildlife conservancies—would protect the animals, treating them as possessions. They could feed them, lease them, breed them and charge hunter a fee for access. “If you want to conserve something," Wilson says, “you have to give it a value. Animals that are considered pests don't have value."

    Privatization could also help reduce grazing pressures. If kangaroos were more valuable than cattle or sheep, farmers would keep less live-stock, which could be good for the environment. Under this scheme, landholders would work with the kangaroo industry on branding, marketing and quality control. The government's role would be oversight and regulation.
