1、The fact cited by the author could hardly illustrate the assumption that. because the author provides only a few samples might not be representative of the completely general group. 3, Do the statistics make any difference:调查只调查了部分情况,忽略了一部分The survey only studies the situation of .; however, many ot

Its conflict of interest in the result of the survey might distort the actual answers of the re
3、spondents. Thus, the author should cite a survey that is conducted by an independent institution.6, When was the survey conducted:时间变化The survey was conduct (during a special period, or a long time ago). It is true that the survey may reflect the opinions/situations of (respondents) at the time when
4、 it was conducted, but situation of/peoples opinion may have changed greatly during the past time. 7, Vague data:数据模糊没有基数The author only informs us that (the percentage/fraction of sub-groups), but we do not know the base amount of (the general group). If the base amount were low, the conclusion wou

6、e answering the questions honestly may lead to (undesirable consequences) for them. Under such circumstances, it is almost impossible for us to expect the respondents to provide accurate information about their opinion toward.10, Are the respondents representative:回答者没有代表性We should also notice that
7、the respondents studied in the survey may not represent the general group of .We all know that in many cases, people who are interested in .might be more willing to express their own opinions about the issue of .than other people are.比较11, False analogy:错误类比AB,A适合BIn the argument the author recommen
8、ds A to carry out same (policies, actions, solutions ) as B, but the analogy between them might be unsubstantiated. Before A decide to draw on Bs experiences, we should take into account and make careful study on the comparability of the two (cities, companies, schools, etc).While it is true that A
9、and B share some common ground on .there are still some obvious differences between them.12, Incomplete comparison /selective comparison /ex parte information:错误对比AB,A不一定比B好The author hastily implies that A is superior to B in . but the comparison between A and B is incomplete.The author only compar

Something may have totally different situation thus (the evidence/results of) could not be properly applied to them. 16, Inferring a future condition from a past cond
12、ition:过去不能推未来In the argument the author suggests that we can (solve current problems or achieve current goals) through methods which have successfully solved the same kind of problems in the past. There is a hidden assumption assumed by the author that all conditions and factors upon which the effec
