3.Original Sentence:"A new report today finds that layering the three vehicle technologies—autonomous, electric and shared-on top of one another could cut carbon emissions 80 percent by 2050 worldwide from a business-as-usual scenario."A. The latest findings reveal that autonomous vehicles alone could reduce worldwide carbon emissions by 2050 without the need for electric or shared cars.B. A recent study shows that separating these three vehicle technologies could increase carbon emissions by 80% globally by 2050.C. Today's report suggests that using only electric vehicles could decrease emissions by 2050,but not as much as combining all three technologies.D. Current research indicates that by combining self-driving, electric, and shared cars, global carbon emissions could be reduced by 80% by the year 2050 compared to current trends.

解析

本题考查对英文句子的理解以及对各选项内容与原句的匹配度判断。解题思路是先准确理解原句的核心意思，再逐一分析每个选项，看其是否与原句表达的信息一致。

  • 原句 “A new report today finds that layering the three vehicle technologies—autonomous, electric and shared - on top of one another could cut carbon emissions 80 percent by 2050 worldwide from a business - as - usual scenario.” 的意思是：今天的一份新报告发现，将自动驾驶、电动和共享这三种车辆技术相互叠加使用，到2050年，与常规情况相比，全球碳排放量可以减少80%。
  • 选项A：“The latest findings reveal that autonomous vehicles alone could reduce worldwide carbon emissions by 2050 without the need for electric or shared cars.” 该选项说仅自动驾驶汽车就能在2050年减少全球碳排放量，无需电动汽车或共享汽车。而原句强调的是三种技术叠加的效果，并非单一的自动驾驶技术，所以选项A与原句不符。
  • 选项B：“A recent study shows that separating these three vehicle technologies could increase carbon emissions by 80% globally by 2050.” 此选项表示将这三种车辆技术分开使用会使全球碳排放量到2050年增加80%。原句说的是三种技术叠加使用能减少碳排放量，并非分开使用的情况，所以选项B错误。
  • 选项C：“Today's report suggests that using only electric vehicles could decrease emissions by 2050, but not as much as combining all three technologies.” 该选项提到仅使用电动汽车到2050年能减少排放，但不如三种技术结合效果好。原句重点在于三种技术结合的效果，未提及仅使用电动汽车的情况，所以选项C不符合原句意思。
  • 选项D：“Current research indicates that by combining self - driving, electric, and shared cars, global carbon emissions could be reduced by 80% by the year 2050 compared to current trends.” 该选项表明当前研究显示，将自动驾驶、电动和共享汽车结合起来，到2050年与当前趋势相比，全球碳排放量可以减少80%，与原句表达的意思一致。
