题目内容
12.The electric revolutionThe main reasons why electric cars are not more popular at present are their price and their relatively small range.
Existing battery systems only allow electric cars (33)to travel (travel) a distance of between 100and 160km.However,this distance may not be a problem for urban drivers.A recent Sydney study reported that 70percent of journeys were 30km or less,and recent data from the US suggests that 77percent of trips (34)taken (take) there are 48km or less.
An innovative company called Better Place is aiming to make electric cars an option for all drivers.It wants to see existing vehicles replaced by electric vehicles which,it says,offer a number of benefits.Firstly,they can be powered by renewable energy which produces zero emissions.(35)What is more important is that electric motors are more efficient and can convert more than 90percent of power into movement.(36)To achieve (achieve) its aim,Better Place plans to use technology already available.
The plan is simple but revolutionary.It starts with the installation of a home charge point,and through this,the vehicle will be plugged into the electricity charge point whenever it is in the garage,typically at night.In the morning,with a fully charged battery,the car is capable of as much as 160km in urban motoring conditions.(37)With the home charge point,the battery can be topped up by charge points at work and at supermarkets.
(38)The battery is linked to a control centre by smart technology inside the vehicle.Better Place can then ensure that the car is charged with electricity from renewable sources at the cheapest price.For (39)longer (long) trips,a navigation system directs the driver to the nearest switch station,(40)where the battery can be replaced with a charged one by a robot within a couple of minutes.
分析 本文主要介绍了革新后的电动汽车的优点;针对电动汽车不太受欢迎的主要原因以及它行驶里程比较短的现状,有一家叫 Better Place 的创新型公司决定要对电动汽车进行革新,力求使它成为所有司机的选择,而且想要看到让这种具备一系列优点的电动汽车取代现有的车辆;首先,使电动汽车通过产生零排放的可再生能源发电;这样,电机有了更高的效率,便能将超过百分之九十的动力转换成运动;为了实现目标,Better Place 公司计划使用已有的技术;另外,他们的革新始于安装家用充电桩;这就使得人们随时可以在车库充电,并且在充满电的情况下,如果在城市道路上行使的话,它可以达到160公里;另外经过革新了的电动汽车的电池也通过智能技术被连接到了车辆内的控制中心;这样,Better Place 便可以确保汽车是以最便宜的价格从可再生能源那里进行充电;对于路途比较长的旅行,导航系统会将司机引导到最近的开闭所;在那里由机器人在几分钟内就可以完成电池的更换.
解答 答案:
33.to travel 考查固定短语 固定短语allow…to do sth.意为:允许…做某事;这里指的是:现有的电池系统只允许电动汽车行驶的距离在100至160公里之间;故填to travel;
34.taken 考查过去分词 固定短语take a trip 意为:旅游;去旅行; 在本句中,take作名词trips的后置定语,并与该名词构成动宾关系,所以应使用它的过去分词形式;故填taken;
35.What 考查连接代词 分析句子结构可知,此处用来引导主语从句;由于该从句缺少主语,意为:…的(问题);本句的意思是:更重要的(问题)是,电机有了更高的效率,便能将超过百分之九十的动力转换成运动;故填What;
36.To achieve 考查动词不定式 分析句意可知,此处在句中作目的状语;意为:为了实现这一目标,Better Place 计划使用已有的技术;故填To achieve;
37.With 考查介词 本句的意思是:有了家用充电桩后,在工作场所以及超市,都可以通过充电桩给电池充满电;此处用来作方式状语;故填With;
38.The 考查定冠词 这里特指革新之后的电动汽车的电池;本句的意思是:该电池通过智能技术连接到了车辆内的控制中心;故用The;
39.longer 考查形容词的比较级 这里指的是对于路途比较长的旅行,导航系统会将司机引导到最近的开闭所;故填longer;
40.where 考查关系副词 根据句意以及空缺处之前的逗号可知,本句是非限定性的定语从句;先行词 the nearest switch station在从句中作地点状语;本句意为:对于路途比较长的旅行,导航系统会将司机引导到最近的开闭所,在那里由机器人在几分钟内就可以完成电池的更换.故填where.
