问题
Which of the following is true within an atom according to the passage? [br] The passage is mainly about ______.
选项
A、charges and electricity
B、the composition of atoms
C、how electricity is generated
D、some electronic phenomena
答案
A
解析
本题问“本文主要讲的是关于……”。这是一道主旨题。文章开始介绍了原子内电荷组成,继而谈了电荷的移动形成电流,又谈到多余电荷的逃逸形成电击现象等,涉及的都是电荷与电的关系,故[A]“电荷与电”正确。[B]“原子的组成”。文中第一段讲的是原子的组成,其他两段不是,所以这一点不能概括全文。[C]“电是怎样产生的”。文章第二段主要介绍电流的形成以及导体和绝缘体的区分,第三段讲的是电荷逃逸的现象,这一项也不能概括全文。[D]“一些电现象”。文中第三段讲的是电荷逃逸的现象,但第二段导体的区分不属于电现象,只是与电有关的知识,所以本项也不正确。
