Question

英语选择题为什么选A不选B

___theories approximate the truth is the day-to-day business of science.

A Determining how closely B How closely to determine C How one determines close D one is close to determining

Answer 1

首先 以how 引导主从句时就为陈述句 B中how应该修饰approximate（程度）, 它表示为how to 怎么样 C应该为 How one determine the distance between A & B is ***** BC删

句意：日复一日的科学研究决定了理论与真理的接近程度。

Determing……truth 本质上是ing引导的主语从句

Answer 2

选A

XXX is the day-to-day business of science.

XXX: determining how closely theories approximate the truth

大意是：day-to-day business of science 就是确定理论与实际到底有多么吻合。day-to-day business of science字面是科学的日常工作。
