American and Japanese researchers are developing a smart car
that will help drivers avoid accidents by predicting when they are about to make
a dangerous move. The smart car of the future will be able to
tell if drivers are going to mm, change lanes, speed up, slow down or pass
another car. If the driver's intended action could lead to an
accident, the car will activate a warning system or override the move.
(111) {{U}}"By shifting the emphasis of car safety away from design of the
vehicle itself and looking more toward the driver's behavior, the developers
believe that they can start to build cars that adapt to suit people's
needs,"{{/U}} New Scientist magazine said. Alex Pentland of the
Massachusetts Institute of Technology collaborated on the project with Andrew
Lin who works for the Japanese carmaker Nissan. (112) {{U}}Tests
of their smart car using a driving simulator have shown that it is 95 percent
accurate in predicting a driver's move 12 seconds in advance.{{/U}}
(113) {{U}}The system is based on driving behavior which the researchers say
can be divided into chains of sub-actions which include preparatory
moves.{{/U}} It monitors the driver's behavior patterns to predict
the next move. "To make its predictions, Nissan's smart car uses
a computer and sensors on the steering wheel, accelerator and brake to monitor a
person's driving patterns. (114) {{U}}A brief training session, in which the
driver is asked to perform certain maneuvers, allows the system to calculate the
probability of particular actions occurring in two-second time segments,"{{/U}}
the magazine said. Lin has also done work on tracking eye
movement to predict driving behavior. (115) {{U}}He said the smart car could be
adapted to monitor eye movement which could give even earlier predictions of
when a driver is about to make a wrong move.{{/U}}
问答题
【正确答案】
【答案解析】“研究人员相信,将提高驾车安全的重点从车辆的设计上转移到更多地注意司机的行为,他们就能着手制追适应人们需要的汽车。”
[结构分析] 句子框架是By shifting the emphasis... and looking more..., the developers believe that they can start to build cars that adapt to suit people's needs。此句的主干是the developers believe that...,宾语从句里 cars由that引导的定语从句修饰;前面介词by引导由and连接的并列动名词构成方式状语;adapt to意思为“适应”,这里可翻译为“面向,旨在”。
问答题
【正确答案】
【答案解析】用模拟驾驶装置对智能汽车的测试表明,提前12秒预测驾驶员动作的准确性达到95%。
[结构分析] 句子框架是Tests... have shown that it is 95 percent accurate in predicting a driver's move 12 seconds in advance。此句的主干包含了一个宾语从句:Tests... have shown that...,that宾语从句中介词in表示“在…方面”。using a driving simulator是现在分词结构作定语,修饰smart car,move在这里作名词,in advance翻译为“提前”。
问答题
【正确答案】
【答案解析】这套系统是以驾驶动作为基础开发的,研究人员认为可以把驾驶过程分为一系列的动作,包括预备性的动作。
[结构分析] 句子框架是The system is based on driving behavior which... can be divided into chains of sub actions which include preparatory moves。此句的主干是一简单句:The system is based on driving behavior,但后面有两个which引导的定语从句,第一个修饰driving behavior,第二个修饰sub-actions; the researchers say作为插入成分。chains of翻译为“一系列”。
问答题
【正确答案】
【答案解析】在一个短暂的训练过程中,驾驶员被要求完成一些规定动作,这个训练过程让系统计算出在两秒钟的时间内发生某些特定动作的概率。
[结构分析] 句子框架是A brief training session,..., allows the system to...本句是个简单句,主语后有 which引导的非限定性定语从句修饰,occurring in...现在分词作定语修饰actions。

【正确答案】
【答案解析】他说可以将智能汽车进行改造使之能够监视眼球的活动,这样就能更早地预见到司机将要做出的错误动作。
[结构分析] 句子框架是He said the smart car could be adapted to... movement which could give even earlier predictions of when a driver is about to make a wrong move。这句中首先包含了一个宾语从句:He said that...;宾语部分里又含有which引导的定语从句,但它并不是修饰紧在其前的eye movement,这里 which是指代前面说的整件事;when引导的从句作介词of的宾语;be about to do表示“将要做…”。
