38、ee what disciplinary assumptions are challenged;question the significance of your ideas;emphasize the important results and address limitations in a realistic manner.An abstract will nearly always be read along with the title,so do not repeat or rephrase your title.It will likely be read without the

39、 rest of the document,however,so make it complete enough to stand on its own.Your readers expect you to summarize your conclusions in an abstract,as well as your purposes,methods and main findings.Emphasize the different points of your study in proportion to the emphasis they receive in the body of

40、the document.DO NOT refer in the abstract to information that is not in the document.This is very important and is a little like“truth in advertising.”You do not want to give your reader the impression that your study covers information it does not actually contain.Avoid using the first person I or

41、we.In addition,whenever possible,choose active verbs instead of passive ones(ex:use the study tested”instead of“it was tested by the study”or“I tested in the study”).Avoid,if possible,using trade names,acronyms,abbreviations or symbols in your abstract.You would have to explain these names which wou

42、ld take up valuable room/words.Use non-evaluative language in your abstract;report instead of comment upon your findings.Use key words from the document to help indexers more accurately index your document for future research.Ease your readers/audience into your topic.Or,in other words,be sensitive

43、to the needs and knowledge of your audience.What might seem perfectly obvious to you after working on a longer writing or research project will often be brand-new to your audience.Dont procrastinate!It is best to write the abstract immediately after you finish your project while the ideas are still

44、fresh in your mind.Remember,a well written abstract often can ensure wide publication since many computerized databases and printed indexes reprint abstracts so scholars can keep up with each others work,and associations and corporations often publish abstracts in given fields and mail them to appro

45、priate researchers and scholars,etc.Thus,if you want to ensure that your work has an impact on your field,you should work as hard as possible in presenting a precise and engaging abstract.1.Complete the following sentences by translating Chinese into English.Task RealizationBackgroundBackgroundPurpo
