13、 its importance a.Size of meetings b.Locations of meetings 2)Importance of meetings tourism in postindustrial urban renewal a.Growth in the meetings tourism market in the U.S.b.Growth in international conferences c.Importance of meetings tourism in comparison to leisure tourism in Europe,2.This ques

14、tion usually generates some debate,but here is one possibility.Statement 1）could be a new sentence(7),while the point in Statement 2)could be incorporated into sentence(8)after the citation.Sentence(8)could then be split.The latter part of the sentence,after making,could be rewritten as a new senten

15、ce(9).3.Presumably there are other definitions for meetings tourism,and this is the one that the authors have chosen to use.,1)正式的句子定义(1)正式的句子定义要素 常见的超级坐标词/类标词有：technique,method,process,device,system(2)删除在下列情况下，你可以减少限制性关系代词A.定语从句仅有关系代词、be动词、一个或多个介词短语B.定语从句由被动态动词加上一些额外的信息C.定语从句含有关系代词、以-ble结尾的形容词和额外的信

20、rcise G:P.132 The whole passage seems like neither a competing nor a contrastive definition.Instead,its an extended definition.,5)比较性定义比较定义基本上有两类：1)呈现一个概念是如何随着时间的流逝而变化 的这样一种史实陈述。2)呈现对当代各位专家是怎样不同地看待此概 念所做的一个全面性的评述。Key to Exercise H:P.133 1.Sentences 4,7,and 10.2.Present tense.The theories are timeles

21、s.Although they were formulated in the past,they were still widely accepted today.,3.S5:In other words S6:therefore S7:on the other hand S8:for example S9:In other words S16:For instance The purpose is either for explanation/exemplification or to indicate contrasts among the competing theories.4.The

22、re are a number of possibilities:perhaps a discussion of the writers own theory of humor in which flaws in the other theories are presented.Perhaps an expansion of one of the theories;most likely an analysis of a humorous situation play,hook,movie,or something else),using each of the competing theor

23、ies or demonstrating how they do not always work.,5.The text,is actually a general review of different theories.It is mostly a GS text,but it doesnt get more and more specific with each sentence.The text reaches a particular level of specificity and then remains at that level.It doesnt provide very

24、specific detail for each of the theories.6.No.It simply says that modern theories are variations of old ones,and it only specifically mentions superiority theory and incongruity theory.(There is no complicated motive behind this.Chris simply had exhausted all her resources and did not,look for moder

25、n versions of all the theories.),7.If Chris expressed a preference,it was not intentional.Note the absence ofevaluative language.However,she has a strong preference for incongruity theory.If she had wanted to express a preference,she would have discussed the incongruity theory last,rather than in th

26、e middle.Discussing the preferred point of view in final position is a common rhetorical strategy.,2.问题-过程-解决方法 泛论-具体文本写作通常是描述性的、说明性的比较而言，问题-解决方法文本通常更具论证性评估性。1)问题-解决方法文本结构Key to Exercise I:P.1341.No answer is given.2.Sentences 1,4,10,and 14 are important for the four parts of the text.Most students

27、feel that these are most important.However,we can also note that the major claim or conclusion is given in sentence 13.,3.He states that there is a problem with the databases used in Garfields study and then provides support for this assertion.Next,he gives a very concrete example of a serious weakn

28、ess the inconsistency regarding Arabic-language science journals.This example should raise some doubts with the reader,making it apparent that there is a problem.(Note the general-specific movement in the paragraph.),4.Considering that this is a very short text,the amount of detail is appropriate.If

29、 it were longer,then it would make sense to critique the databases and the methodology used to arrive at the 80%figure.The number of examples is dependent on the length of the text.Certainly one more would be nice.Can you supply one?,5.There are several examples of hedging here,particularly in the s

30、econd and third paragraphs.But the number of hedges should not be equated with the level of uncertainty.Notice that in the second paragraph,we have hedged generaliz-ations,but in the third there are several unhedged statements of results for single studies.Nevertheless,overall,the two paragraphs see

31、m similar in terms of the level of conviction.,6.Garfield 1983;Najjar 1988;Throgmartin 1980;Velho and Krige 1984;Warren and Newhill 1978.All but one of these citations are twenty or more years old.Given that changes in language policy are likely to be evolving,the reference list looks rather dated.7

33、re presented in the first paragraph,while in the first sample they spread over two different paragraphs.In contrast to the previous text,the situation requires little explanation only one sentence is necessary.Also the nature of the problem is clearer here than in the previous text.We can all imagin

34、e the seriousness of the problems associated with the lack of fresh water.A one-sentence paragraph is not a good idea,so it makes sense to continue the paragraph with a discussion of the problem.,2.Nets are erected water droplets of the fog are collected by the nets water flows from the nets to trou

35、ghs water flows through filters into storage tanks water is chemically treated water flows to households.3.Present tense is used because this is a repeatable process.4.is now being tested,are attached,are trapped,is then piped,is chemically treated.,5.The progressive is appropriate here because the

36、testing is being done at the time of writing.From the authors perspective,it is in progress and has not been completed.Although the progressive is rare in scientific academic English,it can often be used to describe contemporary change(e.g.,Scholars are beginning to change their ideas about.)The ver

37、b to be can indeed be used in the progressive.,6.now,approximately,when,then,chemically,finally.Sentence 4:this absence of rainfall Sentence 14:this collection system Both of these occur in the final sentence of their respective paragraphs.They serve to summarize the main point of the paragraph.8.Th

40、 15 and 16.,3)语言聚焦：解决方法中的动词与施动者(1)被动语态被动语态在过程描述中常常起着很重要的作用 在正式的学术写作中，我们会更多地看到 by+过程 或 by+非人为施动者 的句型Key to Exercise K:P.137 1.Bacteria in meat can be killed by a brief but intense period of radiation between butchering and packaging.2.Possible harmful effects of drugs can be reduced by carrying out c
