问题 In pollen dating, geologic happenings are dated in terms of each other, and one can get just so far by matching (i)____ sequences; but in radiocarbon dating the scale of time is measured in (ii)____ terms of centuries or years.

选项 A、random…selective
B、irrelevant…usable
C、vague…relative
D、independent…absolute
E、imaginary…calculable

答案 D

解析 空格(ii):
-方程等号:but表示转折,前后句意反义重复。
- 强词和对应:pollen dating的方法是通过彼此来确定,in terms of each other表示的是相对的概念。根据but可知,in terms of each other(相互之间)指向空格(ii),取反,空格体现“绝对”。selective选择的,usable可用的,relative相对的,absolute绝对的,calculable可计算的。选项D合适。
空格(i):
- 方程等号:and连接平行结构,前后同义重复。
- 强词和对应:pollen dating的方法可以根据each other(彼此)来确定,根据so far可知,取反,in terms of each other指向空格(i),取反,体现“不相对”。random随机的,irrelevant不相关的,vague模糊的,independent独立的,imaginary想象的。答案选D。
