一些逻辑训练的谜题：娜塔莎、十二点钟和茶
我的同事，娜塔莎喜欢小孩子，就给他们出了一些题。而我在十二点钟和娜塔莎闲谈时，总会为她补充一些，而她也觉得这还不错。到了下午，我们一起喝茶时，我们会把饼干放在鸟笼边，猫头鹰则会将其啄成碎片。我们的生活就是这样悠闲地度过的，和这所大学里的本科生的终日忙碌仿佛处在两个世界，他们没有心情欣赏校园里的建筑多么有艺术感，也看不见柳树和池塘蕴含着十四行诗——就算你不是莎士比亚也可以发现——只等着被抓出来和记录下来，但我们是刚好反过来的。
在这里，我会归纳一些我们设计的，助益于逻辑能力的谜题。

In this rigidly singular sentence, given as an important premise to the puzzle, a "they" does make the grammar awkward though.
If and ONLY if that a Chinese is also an English speaker, ta knows P(-10). This is a consistent singular third-person sentence.
If and ONLY if that a Chinese is also an English speaker, they know P(-10). The verb "know" is no longer singular due to "they" but the sentence is still singular. In common English, it is just a sloppy custom. In comedian's language, this is a joke. In old academic papers, people say "he/she knows," which is no longer politically correct. Then, there's ze. Then, my "ta" becomes useful.
