【资料节选】

In science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.

1. The word "this" in the 3rd sentence in paragraph 1 refers to ______.

A) a good example

B) an imaginary model

C) the kinetic molecular theory

D) an observed event

答案解析:

[1]B第三句话中的代词“this'’指代前一句提到的“an imaginary model"。因为这个例子就是要说明在动力分子理论中,气体被描绘成由许多不停运动的小分子所组成,即前句中“理论常包含一个想象模式来帮助科学家描绘事件的产生过程。”examda
