A new report today finds that _____ the three vehicle technologies-autonomous,electric and shared-on top of one another could cut the carbon emissions.( )
A. put
B. layer
C. layering
D. including
题目解答
答案
C. layering
解析
本题考查动名词的固定搭配及语境逻辑。关键点在于识别短语 "layer...on top of" 的固定用法,表示“分层叠加”。需注意主句中 "that" 引导的成分需用动名词作主语,而非动词原形。
选项分析
- A. put:动词原形,无法直接作主语,且与 "on top of" 搭配不当。
- B. layer:动词原形,单独使用缺少宾语,无法构成完整意义。
- C. layering:动名词形式,与 "on top of" 构成固定搭配 "layering...on top of",表示“叠加技术”。
- D. including:动名词,但表示“包含”,与“叠加”语境不符。
语法验证
句子结构为 "finds that + 动名词短语",需用动名词作主语。"layering the three technologies on top of one another" 符合语法和语境要求。
