我们必须好好准备，一定不要有差错。

We must be well prepared, there must be no slips.

《柯林斯英汉双解大词典》

对于谬误，我们需要有两点准备，第一，谬误是非常常见的现象，至少对于无心的听众和读者而言，结论本身却可能显得很有说服力。

It is important to realize two things about fallacies: first, fallacious arguments are very, very common and can be quite persuasive, at least to the casual reader or listener.
