(完整)英语作文 Opportunity cost Opportunity cost is the cost we pay when we give up something to get something else.It refers to the most desirable thing given up， not the aggregate of the things we have given up.In microeconomic theory， the opportunity cost of a choice is the value of the best alternative forgone, in a situation in which a choice needs to be made among several mutually exclusive alternatives of given limited resources. Why is the reason for the appearance of opportunity cost? Because scarcity。 No matter you believe or not， we all face the problem of scarcity. Almost everything in your daily life is scarce。 You would benefit from a larger room or apartment， so you have a scarcity of space。 You have only two pairs of shoes and could use a third for hiking, you have a scarcity of shoes. You would love to take a trip to Chicago， but it is difficult for you to find the time or the money to go — trips to Chicago are scarce。 Because of scarcity, each of us is forced to make choices. We must allocate our scarce time to different activities and we must allocate our scarce spending power among different goods and services。 The opportunity cost of any choice is what we give up when we make that choice。 According to those information of opportunity cost， we should know that all economic decision made by individuals or society are costly， we have to measure our choices and choose the best one。 Academic ethics In recent years， there have been more fabrication， falsification and plagiarism incidents on the Internet， which arises great attention to research ethics in the society. Ethics are moral beliefs and rules about right and wrong。 An ethic of a particular kind is an idea or moral belief that influences the behavior， attitude and philosophy of a group of people。 Academic ethics refers to the norms and rules to be observed in conducting academic research. Some people think it is unnecessary to understand and adhere to academic ethics, while others hold the different opinion. As far as I am concerned, research ethics plays an very essential role in our study life. On the one hand， it has great significance to universities and colleges. As we all know, actions of misconduct often appear in universities and colleges。 Strengthen the Scientific Norms of Science and Ethics and Manage Academic Misconducts from the Source will be useful to form a good atmosphere of adhering to academic integrity, improving academic personality and maintaining academic dignity。 On the other hand, it also be beneficial to the whole academic public system.

Grant strategy and details Strategy is about detailed planning，a battle of wits between the leader or manager and whatever forces he or she is pitted against。 Grant strategy is the general planning which helps you to act in a way that moves you closer to the final goal, rather than in a way that merely solves the immediate problem. Some people think that grant strategy is the most essential element to success, while others hold the different opinion that they think details are more important. As far as I am concerned, grand strategy has the same position as details. On the hand， grant strategy can provide a general direction when you make a plan。 Many business leaders have told us that get the grand strategy right and then sweat the execution； get it wrong and your are doomed。 It is obvious that without brilliant conception and faultless planning, the minor strategies that you employ in pursuit of the overall goal will fail。 On the other hand, details can make a grant strategy from a ideal to a reality。 Strategy is important， but it is a compass， not a road map. It tells you in which direction you are heading, but the important bit is how you get there. All is all， grant strategy is direction while details are efforts to make the grant strategy come true， they are equally important.

As far as I am concerned, hospice is a better choice for those who has just few days left to live。 (完整)英语作文 On the one hand， hospice can provide a team of dedicated professionals—--including social workers， health aides, chaplains, and nurses———work together to provide not only physical but also emotional and spiritual support.

Hospice care can take place at home, at a hospice center, in a hospital or in a skilled nursing facility。 It allows patients to spend their final life at home and stay with their loved family numbers。 The caregivers try to control pain and other symptoms so a person can remain as alert and comfortable as possible.The care also try their best to help people who are dying have peace, comfort， and dignity.
