问题
According to a recent report published by the World Health Organization, there are a number of regional and national______of the cold virus.
选项
A、variety
B、variation
C、variations
D、variability
答案
C
解析
空格在形容词national后,因此是需要名词的位置,选项也都是名词。句子内容是感冒病毒在不同地区和国家有许多变异,填意为“变化形式;变化,变动,变更”的variations合适。提及许多种类时使用a variety of或varieties of的形态,variability是单纯表现可变性或多样性的性质本身的名词。另外,如果知道“a number of+复数名词”的形态的话,就能很容易知道要选择复数名词variations。
