问题 单项选择题

19世纪前,技术、科学发展相对立。而19世纪的电气革命,是建立在科学基础上的技术创新,它不可避免地导致了两者的结合与发展,而这又使人类不可避免地面对尖锐的伦理道德问题和资源环境问题。

以下哪项符合题干的断定?()

Ⅰ.产生当今尖锐的伦理道德问题和资源环境问题的一个重要根源是电气革命。

Ⅱ.如果没有电气革命,则不会产生当今尖锐的伦理道德问题和资源环境问题。

Ⅲ.如果没有科学与技术的结合,就不会有电气革命。

A.只有Ⅰ

B.只有Ⅱ

C.只有Ⅲ

D.只有Ⅰ和Ⅲ

答案

参考答案:D

解析:

根据本题题干可以断定:(1)电气革命是科学技术结合发展的充分条件。(2)科学技术结合发展是人类面对尖锐的伦理道德问题和资源环境问题的充分条件。由(1)和(2)可得“电气革命是人类面对尖锐的伦理道德问题和资源环境问题的充分条件”。据此可知,产生当今尖锐的伦理道德问题和资源环境问题的一个重要根源是电气革命,所以Ⅰ项成立。由(1)可得“科学与技术的结合是电气革命的必要条件(如果p是q的充分条件,则q是p的必要条件,反之亦然),即如果没有科学与技术的结合,就不会有电气革命”,所以Ⅲ项成立。Ⅱ项不符合题干的断定,因为由题干可推出电气革命是人类面对尖锐的伦理道德问题和资源环境问题的充分条件,不能推出前者是后者的必要条件。

The nurse had him take a       in the waiting area,     him it would be at least 40 minutes      someone would be able to see him. I saw him     his watch and decided, since I was     busy ---my patient didn’t     at the appointed hour, I would examine his wound. While taking care of his wound, I asked him if he had another doctor’s appointment. The gentleman said no and told me that he      to go to the nursing home to eat breakfast with his     . He told me she had been       for a while and she had a special disease. I asked if she would be      if he was a bit late. He replied that she      knew who he was, and that she had not been able to     him for five years. I was      , and asked him, “And you     go every morning, even though she doesn’t know who you are?”  He smiled and said, “She doesn’t know me, but I know who she is.” I had to hold back      as he left.
Now I      that in marriages, true love is     of all that is.  The happiest people don’t      have the best of everything; They just      the best use of everything they have.      isn’t about how to live through the storm,  but how to dance in the rain.
