According to statistics overweight or obese people_over 60 percent of adult Americans now.
A. care for
B. account for
C. speak for
D. take care of
题目解答
答案
B. account for
解析
本题考查动词短语的辨义,核心在于理解各选项短语的常用含义及用法。关键点在于识别题干中“占...比例”的语境,需选择能准确表达此意的短语。account for在此表示“占...的比例”,是本题的解题核心。
选项分析
A. care for
含义:表示“喜欢”或“照顾”,如:
- I care for classical music.(我喜欢古典音乐。)
- She cares for her sick mother.(她照顾生病的母亲。)
排除理由:题干需表达“占比例”,与“喜欢”或“照顾”无关。
B. account for
含义:表示“占...的比例”或“解释...的原因”,如:
- Smoking accounts for many health problems.(吸烟导致许多健康问题。)
- Women account for 50% of the workforce.(女性占劳动力的50%。)
正确性:题干中“overweight or obese people”占60%的语境与该短语的“占比例”用法完全匹配。
C. speak for
含义:表示“代表”或“为...说话”,如:
- I can't speak for her.(我不能替她说话。)
排除理由:与“占比例”无关。
D. take care of
含义:表示“照顾”或“处理”,如:
- She took care of the children.(她照顾孩子。)
排除理由:与题干语境无关。
