问题 单项选择题

关于基本粒子目前最被认可的理论是“标准理论”。它约在30年前确立,已发现的基本粒子都可以根据这一理论进行解释。100多年来,质子、中子、电子等基本粒子陆续被发现。面对这些成绩,有人认为,宇宙间的基本粒子被发现得差不多了,即使有,也可以用现有的理论解释,因而不会给人们带来太大的惊奇。以下哪项如果为真,最能反驳以上观点()

A.基于“标准理论”而被发现的基本粒子很少

B.基于“标准理论”做出的某些预测未在实验中得到证实

C.新发现的基本粒子与“标准理论”做出的预测不相符

D.有科学家提出了颠覆人们以往对基本粒子认识的新理论

答案

参考答案:C

解析:

本题为削弱论证类;题干的观点是新发现的粒子可用“标准理论”解释。而C项新发现的粒子与“标准理论”做出的预测不符,也就是不能用“标准理论”解释,削弱了题干的论证。其他选项都不能削弱题干的观点。答案选择C选项。

I am not sure when I started listening to the radio. In the evening, I like listening to some talk programmes. The host’s (主持人的) beautiful voice makes me relax. The host often has the same feelings as the audience about love, friendship, life and so on. I am often moved (被感动) to tears. I usually go to bed at 9:30 pm and then I begin to listen to the play on the radio in bed. I can only listen to the sound, but I am always interested in guessing who they are and what they look like. I often fall asleep while listening. During lunch and supper time, I listen to the radio, too.

I like listening to music because it can make me quiet. I also like thinking about something while listening to music, for example, what I shall do tomorrow, that I have to call my family tonight and that I should send short messages to my friends on Christmas Day.  

You see, radio is important in my life, like a friend.
