问题 There are great ______ in countries?greenhouse gas emissions, especially in per capita terms: while the United States and China are similar in aggregate emissions, United States per capita emissions are a huge multiple of China’s.
A. distortions
B. disparities
C. fluctuations
D. advances
E. variances
F. vacillations

选项

答案B,E

解析 -方程等号:冒号,同义重复。
-强词和对应:冒号前说国家之间的温室气体排放有很大空格,冒号后面的主句说美国的人均排放量是中国的好几倍,强词是a huge multiple of,指向空格,根据冒号同义重复,空格应填入a huge multiple of的同义词。选项里有两组同义词,第一组是disparity与variance差异,第二组是fluctuation与vacillation波动,所以答案选择BE。其他选项,distortion扭曲,advance进步。
