    Practice 7　　Think carefully about the issue presented in the following excerpt and the assignment below.　　Prudence shall be our guiding principle. When faced with a conflict, or a divergent path in the course of life, we shall always make caution our ally. Recklessness and rash action lead not to fruitfulness, but only to regret at the haste of our decisions. Often times, people ask me how I have been so successful in business. “Everything you touch turns to gold,” they say. “What’s your secret?” they wonder. When I reflect on my decisions, I realize that the key to my success is nothing more than simple opportunism. When I saw an opening, I jumped at it. While everyone else was standing still, agonizing over the correct course of action, I went in feet first, with no hesitation. That is the key to my Success.　　Assignment: Consider the two contrasting statements above. Which best reflects your view on life? Plan and write an essay in which you develop your point of view on this issue. Support your position with reasoning and examples taken from your reading, studies, experience, or observations.

    正确答案： 【参考范文】
    I have always believed that when opportunity knocks, one should answer the door. There are two main reasons behind this way of thinking: the first, opportunities could pass us by and never occur again; and the second, no matter how hard working one is, a lucky break may lead to the success one has been dreaming of. This is not the same as recklessly jumping into any plan of action that presents itself. Rather, by weighing possible outcomes, positive prospects should be easily detected.
    My older sister, Elise, attended Georgetown University in Washington, DC a few years ago. Though she liked the campus, her classes, fellow students, and even the city, Elise rarely ever left the neighborhood of Georgetown to explore DC. Over the semesters and summer holidays, my sister never applied for a single internship with the various powerful institutions and companies in DC, including the congressional offices. Upon graduation, Elise found herself with a small copy editing job at a start-up newspaper in Portland, Oregon. She realized a few months before graduating that her interests were in public service, but possessed absolutely no experience in the field. Elise realized that she had lived in the political and public sector apex in the nation for four years, and never taken advantage of personal contacts in DC or Georgetown to build future connections and job prospects. My sister’s story has been a warning to me, not only to make use of every opportunity I know of, but also to seek out ones that are not obvious.
    Another family member’s experience also taught me the importance of chance prospects play in success. My father had tried for years to be hired as a teacher at a local private school. Though he applied multiple times over a decade, hoping to earn the coveted and well-paid position of head of biology, the school always informed him that there were no vacancies. He had all but given up on teaching and decided to pursue a research position when, out of the blue, my dad decided to attend a job fair in a nearby town, and ran into the principal of the private school, who informed him of an opening. Despite the possibility of attaining a biochemistry research position, my father attended two interviews with the school, and after one week, my father was finally hired. His experience reminds me of the importance of persistence, but equally as necessary, the significance of knowing when to rely on lucky opportunities for success.
    Ambitious people require more than perseverance, talent, and knowledge to achieve their goals. Opportunity is an underrated, not often talked about factor in success, but almost every successful person will admit that luck has played a positive role at some point in his life.

    Practice 11　　Think carefully about the issue presented in the following excerpt and the assignment below.　　It is easy to make judgments about people and their actions when we do not know anything about their circumstances or what motivated them to take those actions. But we should look beyond a person’s actions. When people do things that we consider outrageous, inconsiderate, or harmful, we should try to understand why they acted as they did.　　Assignment: Is it important to try to understand people’s motivations before judging their actions? Plan and write an essay in which you develop your point of view on this issue. Support your position with reasoning and examples taken from your reading, studies, experience, or observation.

    正确答案： 【参考范文】
    Why do people do the things they do? Sometimes it’s not that difficult to understand a person’s motivation; A father may choose to work a second job, which may take him away from his family for long periods of time. He doesn’t want to be an absent father, but he believes that his actions will eventually benefit his family. He is motivated by his love for his wife and children. A mother may choose to forego buying herself new clothes or jewelry so that she can be sure her children have enough to eat, nice clothes, and toys. Her motivation is also her love of her family. But when it comes to people whose motivations are a mystery to us, it is always important to try and decipher their feelings so as to help them (or keep them from hurting anyone else).
    What motivates certain people to kill? If we can answer that question, we may be able to identify such inclinations in others and so prevent them from acting out their anger. For surely it is anger that frequently leads to violence. A political assassin, for example, is typically infuriated by the way his country is being run by the current leaders. If there had been some way to know how outraged Lee Harvey Oswald was, or SirhanSirhan, or James Earl Ray, there might have been some way to prevent the deaths of John Kennedy, Bobby Kennedy, and Martin Luther King, Jr. If only someone had been able to gain some insight into the workings of Timothy McVeigh’s maddened mind, the tragedy of Oklahoma City in 1995 might have been averted.
    In other cases, it is not anger, necessarily, but more likely despair that motivates people to commit desperate acts. In 1995, Susan Smith was convicted of the unspeakable act of drowning her two young sons by rolling her car into a lake with them strapped inside. Later, authorities found out that she herself had had a terrible childhood (she was regularly molested by her stepfather) and twice had tried to commit suicide. If anyone could have understood this tormented woman’s mentality, those two little boys might have been saved.
    It is easy to condemn a person for committing a despicable act. It is much harder to discover what their motivation was for acting in such a tragic way, but it is worth the effort.
