The (i)________ of molecular oxygen on Earth-sized planets around other stars in the universe would not be (ii)_______ sign of life: molecular oxygen can be a signature of photosynthesis (a biotic process) or merely of the rapid escape of water from the upper reaches of a planetary atmosphere (an abiotic process).
Blank (i) Blank (ii)
A. dearth D. a controversial
B. presumption E. an unambiguous
C. detection F. a possible
选项
答案
C,E
解析
空格(i):
- 方程等号:冒号,同义重复。
-强词和对应:本句开始有很多介词结构倒装,大意是氧气分子的空格(i)不会是生命迹象的空格(ii)。由于两空同向,本题可以通过空格(ii)做出空格(i)。依据空格(ii)可知本空应填入一个表示“有”的正向词。dearth缺乏,presumption假设,detection发现。本题选C。
空格(ii):
- 方程等号:冒号,同义重复。
- 强词和对应: 冒号后说氧气分子可以是光合作用的标志,或者仅仅是水的流失。因此冒号后的3s版本是氧分子不一定代表有生命。根据冒号同义重复,又由于空格(ii)之前出现not,可知空格(ii)应填入表示“一定”的词。controversial有争议的,unambiguous明了的,possible可能的。答案选E。
