For many years, scholars have regarded My Mortal Enemy as somewhat of an enigma. Written in only a few months during the early spring of 1925 and published in 1926, Willa Cather's shortest novel was sandwiched in between The Professor's House (1925) and Death Comes for the Archbishop (1927). While the subject matter of these latter two works can be traced to Cather's experience in the desert Southwest, My Mortal Enemy seemingly has nothing to do with these subjects or her Nebraska roots; it appears to have come out of nowhere, puzzling those who have tried to fit this rather irregular work into a logical progression of Cather's artistic development. The question of what caused Cather to write such a novel at this point in her career, for example, has still not been answered definitively. One commonly held hypothesis (假说) was first voiced by Marcus Klein, who in his 1961 introduction to the novel wrote that for Cather, “The story of Myra Henshawe must have been a personal crisis”. Klein, though, acknowledged that he could not prove his theory, “because there is available no record other than the novel”. Emmy Stark Zitter has recently argued that in My Mortal Enemy and Sapphira and the Slave Girl(1940) Cather exercises the autobiographical impulse (冲击) by putting details of her own life into her fiction, but, like Klein, she is unable to name which “details” of her life Cather drew on in writing My Mortal Enemy.

    As hinted (暗示) in the above statements by Klein and Zitter, much of the general uncertainty about the meaning of My Mortal Enemy can be traced to the absence of a persuasive theory as to who the real-life models for the novel's characters were and what Cather's relationship to them was. Cather herself wrote in a 1940 letter that, in James Woodress's paraphrase, “she had known Myra's real-life model very well, and the portrait drawn in the story was much as she remembered her”; Cather also added that the woman had died fifteen years before My Mortal Enemy was published, and that many relatives of this model later wrote to her to say that they recognized the “real” Myra from her description in the novel. Given such hints and Cather's liking for drawing on her experiences in Nebraska for characters, settings, and plots, it is quite understandable that scholars have thus looked to Red Cloud and Lincoln for possible sources of the people and events depicted in My Mortal Enemy.

    In light of the evidence presented in this article, though, I believe that Cather intended her comments about the model for Myra Henshawe to serve as red herrings (转移注意力的言语) that would protect her relationship with the couple who were the prototypes (原型) for the Henshawes, both of whom were still alive in 1925. Mark Madigan has recently confirmed how Cather in 1905 had to hold off publishing “The Profile (传略)” because of fears that the main character might recognize herself and commit suicide, and twenty years later Cather would have been well aware of how her description of the Henshawes might have affected both the real-life wife (who died in 1929) and husband (who died in 1949) if they had recognized themselves. It is my argument that the Henshawes were modeled after people Cather knew not in Nebraska but rather in New York: S. S. and Hattie McClure. Myra's uncle, John Driscoll, was modeled after Hattie's father, Professor Albert Hurd.

    Possibly most important, identifying the Henshawes as the McClures allows us to more conclusively identify Cather herself with Nellie Birdseye. Nellie and Cather, both Midwestern onlookers and recorders, experienced four distinct stages in their relationships with the Henshawes and the McClures (especially with S. S.) My Mortal Enemy, I believe, was an extended attempt by Cather to deal with certain aspects of her own past and to move on in a world stripped of romantic illusion.

    Recently actor Adrien Grenier has launched(发动)a campaign to reduce the amount of single-use plastic usage in order to protect and save marine (海洋的)wildlife and the environment. Plastic drinking straws are among many single-use plastic products contributing to the great loss of marine life, but they're a great place to start because they're something that are used by millions of Americans who are unaware that they're so damaging.

    Americans use more than 500 million straws daily, which is enough to fill 127 school buses each day and they can't be recycled. That means plastic straws might end up in oceans, where fish and other marine wildlife mistake the small bits for food and swallow them. After seeing a photo of a beached whale with a belly full of plastic, Grenier felt the inspiration to launch the Lonely Whale Foundation, hoping to inspire and educate others on the challenges faced by marine wildlife.

    Along with stopping the use of straws, Grenier hopes to educate consumer on the dangers of other single-use plastic items such as grocery bags and water bottles. While many Americans use these plastic products in their daily life, there are many alternatives that can help protect the environment such as straws made from stainless steel, glass, and even bamboo instead of plastic.

    In addition to quitting your straw habit, you can further help the environment by taking the I Choose to Reuse commitment, and stop your use of single-use coffee cups, checkout bags and bottled water. Instead, take advantage of any number of alternative reusable products.

    Need another reason to stop drinking from straws? Grenier also says using straws can cause wrinkles!

    Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because if smells good or because it tastes good. You may dislike sonic types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one or their senses, while most animals use more than one sense.

    Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied（广泛的）diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

    The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image of unhappy teenagers locked in their room after endless family quarrels.

    An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.” We were surprised by just how positive today's young people seen to be about their families,” said one member of the research team. “They're expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There's more negotiation and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat.”

    So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall. “I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with it.” Susan Crome, who is now 21, agrees.”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”

    Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers' rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”

Let's face it. You're likely reading this article in an effort to avoid some other tasks you're procrastinating (拖延) to learn how to stop procrastination, but the clock is ticking. So why can't you seem to get rid of that?

Though the psychological causes are still debated, there's a human tendency to over or underestimate the value of a reward based on its temporal proximity (时间接近). This is often referred to as temporal discounting. For example, if I offered you $100 today or 110 in a month, most would take the hundred and run. But what if instead I offered you 100 dollars in a year or 110 in a year and one month, you might say to yourself if I can wait a year, I can wait the extra month.

But the time and value difference are the exact same in each example. It turns out that human motivation is highly influenced by how near the reward is meaning. The further away the reward is, the more you discount its value. So being online is more appealing than preparing for your test. The problem is surfing the Internet provides many small quick and continuous rewards unlike your test scores which are a future one.

So how do you overcome the urge to put off so many tasks?

Unfortunately, there is no definite answer, but try rewarding yourself with a timely snack or other enjoyable activities. The Pomodoro Technique makes use of a timer to work for 25 minutes straight and when you've done, this gives yourself the reward with a 5-minute break. Then start the working clock again. Gradually increasing the amount of work time you put in will improve your time management skills.

It's been shown that creating a costly deadline is also an effective way to manage your working habits. And try to enjoy the process of achieving something instead of thinking only our minutes of suffering.
