问题 单项选择题

以上4张卡片均为一面是图案,另一面是阿拉伯数字。现在断定:如果一面是梅花,那么另一面是6。如果要检验该断定正确与否,且只允许翻动以上两张卡片,正确的选择是()

A.翻动第一张和第三张

B.翻动第二张和第三张

C.翻动第一张和第四张

D.翻动第二张和第四张

答案

参考答案:D

解析:

考查复言命题推理。题干要求检验“如果一而是梅花,那么另一面是6”这个充分条件假言命题的真假。只有当图案面是梅花且数字面不是6的时候,该命题才为假。即若图案面不是梅花,或数字面是6,则命题必然为真。因此一、三两张卡片不必翻动即可确定该断定为真。只需翻动图案面是梅花的(看数字面是否是6,是则命题为真,不是则命题为假)和数字面不是6的(看图案面是否是梅花,是则命题为假,不是则命题为真)。故答案选D。

A week ago, I read When Money Talks, Listen! by Rich Ezzo. It took only about an hour to read, and that included one trip to the coffee maker and about 10 distractions (分心)from Alex, our cat, who thinks he is the center of the universe.

When I first received a copy, I thought it was a get-rich-quick type of publication. There is nothing wrong with that kind of book, but my mind just doesn’t chase after dreams of wealth. I figure that if God ever wants me to be rich, he knows where to find my purse.

When I began reading When Money Talks, Listen!, I was overjoyed to find that Rich Ezzo isn’t money hungry either. He, too, is hungry for things far more important than money.

I absolutely love this e-book. Why did I wait a week to write the review ? simple. I wanted to see if the impact it had on me could keep up. After reading the last word of the e-book, I totally agreed with the subtitle(副标题)which promised to forever change the way we thought about money. I had so many thoughts running around my mind that I had to install a stop light to stop some while others made their way into the picture. I had a mental traffic jam, which only goes to show how slow the traffic usually is.

It has been a week and the impact is the same. I guarantee this is an e-book you’ll want to read. I urge you to visit the author’s website, MysterMoney. Com, and to download the e-book. You won’t

regret it.
