If, for instance, 500 subjects were studied, but no more than 50 echoed, the conclusion would be highly suspectable. b The author fails to point out that when the survey was conducted. If the change is very recent, it is possible that insufficient data have been gleaned to draw such a conclusion, an unconvincing one.

看到这类数字一方面可以完全按照样本不足的模板来处理，也可以按照自己的意思来表达：例如：NO.6说"爵士乐在M非常流行"，列举了"去年夏天10万多人参加了M的爵士音乐节"位论据，我们可以这么攻击：10万人是个很大的数字，但是就拥有1千万人的 M来讲，这个数字并不能说明爵士乐在M很流行。

When the digital keyboard according to the 4 or 6 button to switch to the combo box, the keyboard according to the number 1 or 3 key to switch to the "Open" project after the slash by the number of keyboard keys to open the project, this time by the direction of the cursor keys can be heard on the choice of content.

当按数字键盘的4或6键切换到组合框以后，按数字键盘的1或3键切换到"打开"项目以后，按数字键盘的斜线键即可打开该项目，这时候按光标的方向键就可以听到所选择的内容了。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
