1 Argument Example 调查 1, Selective sample:样本选择，一部分被排除在外 One major problem is about the sample the author studied in the survey. the author considers only...(selective sub-groups) although (the sub-groups the author studied) do constitute a significant part of (the whole general population), however, (many other sub-groups) are actually excluded from the survey. Perhaps...or...without ruling out all the possibilities above, the author could not make any general conclusion about...merely based on (selective sub-groups). 4，14，16，45，63，65，67，80，84，88，90，97，123，146，154，156，168，179，185，193，196，207，227，231，232，236，238，239 2, Quantity of the sample 样本数量 ( pointing out that the current sample is too small in its size)(the fact cited by the author) could hardly illustrate the assumption that... because the author provides only N samples of (the general population),however, (the limited sample) might not be representative of the whole general group. thus we cannot accept the author’s conclusion that...before he/she could provide more statistic data about (the situation of other sub-groups). 10，14，33，40，53，69，95，115，123，132，139，150，154，158，167，179，180，188，191，239 3, Do the statistics make any difference:调查只调查了部分情况，忽略了一部分 The information provided by the author is insufficient for the author to reach the conclusion. the survey only studies the situation of ...(an(some) insignificant case(s)), however, many other more essential cases (related to the final conclusion) were ignored in the survey.(we need to know the condition of some other cases about which we care more/ the current case studied in the survey makes little sense on the final conclusion, the author should provide...
