Computers in Cars
You're far from home on a lonely road.Shadowy forests stretch away on both sides.A thick mist(雾)makes it difficult to see far beyond your car's windshield(挡风玻璃).
“Can this be route 90A?”you wonder. if it is,you should be near a town.Yet there's no hint of one .Night is closing in.And you're low on gasoline.
This is a situation where an in-car computer that can navigate would be a big help.
A car computer that navigates?Yes!Such computers exist.Several experimental models are being tested by General Motors,Ford,Chrysler,and several foreign car makers.These computers vary in detail .But they all contain series of maps on videodiscs or videotapes.For example,one computer system contains 13,300 maps covering the continental US.
Before starting out on a trip,a driver can type in the code for the region he or she plans to drive through .The computer then shows a map of that region.At the same time,a tiny radio re-ceiver linked to the computer goes to work.It picks up signals from navigation satellites such as the NAVSTAR network.Using these signals,the computer shows the car's position at all times and displays this position on the map.The computer can also calculate and display the best route to follow.
A navigation computer may also receive and use data about road construction,weather condi- tions,and traffic jams.This information would be displayed to the driver and the computer would also use the information to work out alternate(交替的)routes.
Most cars nowadays also contain computers that help cars run more efficiently .Microproces- sors(微处理机)control certain engine functions by regulating the mixing of fuel. Data on car speed,oil pressure,revolutions per minute,engine temperature,and fuel level can be displayed as digital data(numbers)or warning lights.
Some auto designers suggest that a central computer display be used to clearly present such timely information as car speed and fuel level.Warning lights would indicate a drop in oil pres- sure or a sudden rise in engine temperature .To get more information on these conditions,the driver could call it up on the computer display screen.When needed,the computer could be “asked”to provide navigation aid or information about the car's condition.

The word“navigate”in Paragraph 3 means______.

    Crime Prevention Initiatives The chances that you will be a victim of violent crime are low. But you can avoid risk in the following ways. AT HOME - You should make sure your house or flat is secure. Always lock the door from the inside at night, but you must keep the key nearby, so that you can use it to get out quickly if there is a fire. - You must never give keys to workmen as they can easily make copies. - If you wake up and hear a burglar, stay quietly in bed. Pretend you are asleep. If you feel more confident, switch on the light and make a lot of noiseeven if you are on your own you should call out loudly to an imaginary companion, so that the burglar thinks you are not alone and runs away. You should have a phone or a mobile in your bedroom to alert the police immediately. - If you come home and think you see signs of a break-in, you shouldn't go in, the burglar may be inside. You should go to a neighbour and call the police. ON THE STREET At night: - Always walk facing the traffic, so that a car cannot pull up behind you. - You mustn't go through parks or woods. - If you think someone is following you, cross the road one or two times. If he or she continues to follow you, go to a pub or other public place. - Always carry your bag close to you, but carry your house keys in your pocket so that you can open the door quickly.

    阅读下面的句子,根据文章内容进行判断,正确写“T”,错误写“F”。

    Stop Yelling At Your Kids

    Parenting is hard. If you’re a parent, I’m sure that I don’t need to tell you that our job is a tough one. When you're managing children, it can be difficult to remember that they are still learning. If you find yourself yelling at your kids more often than you want to, here are some ways that can help you reduce the yelling. I’ve been working on this for the past few months and I have to say,it’s been amazing for both the kids and me.

    If you are having an argument with your child, you need to make sure you both take the time to really listen. It gives both of you time to think and really listen to each other, which is important. Kids are more likely to listen to you if you listen to them!

    One of your biggest struggles is to remind yourself of appropriate expectations. You can’t expect that your youngest acts as responsibly as your oldest. You should lower what you expect -taking into consideration things like their age - it can make a big difference. You should do your best to take a moment before yelling and take in a deep breath. It makes a world of difference for you. Instead of yelling, you’d better whisper. It can also help diffuse any situation by making things quieter, not louder. Besides, the more time you spend with your kids, the better you’ll get at communicating with them. You’re both more likely to understand each other.

    If your children aren’t listening or it seems they only don’t listen to you, you don’t take it personally. You should remind yourself that your kids are still learning and they’re not going to be perfect.

    ( )21. As a parent, you may know that parenting is an easy job.

    ( )22. Listening to each other is a good way to stop argument between parents and their kids.

    ( )23. Usually younger kids behave less responsibly than elder children.

    ( )24. Parents should lower their expectation for their kids.

    ( )25. Both yelling and whispering can help make things quieter.

    The Northern Lights
    The Sun is stormy and has its own kind of weather It is so hot and active that even the Sun's gravity cannot hold its atmosphere in check!Energy flows away from the Sun toward the Earth in a stream of electrified particles that move at speeds around a million miles per hour. These particles are called plasma,and the stream of plasma coming from the Sun is called the solar wind. The more active the Sun,the stronger the solar wind.
    The solar wind constantly streams toward the Earth,but don't worry because a protective magnetic field surrounds our planet.The same magnetic field that makes your compass point north also steers the particles from the Sun to the north and south poles.The charged particles become trapped in magnetic belts around the Earth. When a large blast of solar wind crashes into the Earth's magnetic field,the magnetic field first gets squeezed and then the magnetic field lines break and reconnect.
    The breaking and reconnecting of the magnetic field lines can cause atomic particles called electrons trapped in the belts to fall into the Earth's atmosphere at the poles. As the electrons fall to the Earth,they collide with gas molecules in the atmosphere,creating flashes of light in the sky. Each atmospheric gas glows a different color. Oxygen and nitrogen glows red and green and nitrogen glows violet-purple. As these various colors glow and dance in the night sky,they create the Northern Lights and the Southern Lights.
    Watching auroras is fun and exciting,but normally you can only see them in places far north like Alaska and Canada. The movement of the aurora across the sky is usually slow enough to easily follow with your eyes but they can also pulsate,flicker,or even move like waves.During solar maximum,auroras are seen as far south as Florida,even Mexico!
    Auroras often seem to be very close to the ground,but the lowest aurora is still about 100 kilometers above the ground,a distance much higher than clouds are formed or airplanes can fly. A typical aurora band can be thousands of kilometers long,a few hundred kilometers high,but only a few hundred meters thick.
    We hope you are able to travel to far north places like the Arctic Circle and see the Northern Lights at least once during your lifetime. We know you will never forget it!

    An aurora is generally close to the ground and is very long and thick.
    A: Right
    B: Wrong
    C: Not mentioned

    答案:B
    解析:
    题干意为“太阳的引力太弱,等离子体逃离太阳,流向地球”。利用题干中的细节信息词/短语the Sun's gravity, plasma, Earth作为定位线索,在第一段中找到相关句: The Sun is stormy and has its own kind of weather. It is so hot and active that even the Sun's gravity cannot hold its atmosphere in check!Energy flows away from the Sun toward the Earth in a stream of electrified particles that move at speeds around a million miles per hour. These particles are called plasma,and the stream of plasma coming from the Sun is called the solar wind. The more active the Sun, the stronger the solar wind.定位线索词集中出现在第一段中,因此重点关注第一段。第一段意为“太阳是多风暴的,有它自己独特的气候。太阳非常热,而且活动又极为剧烈,以至于太阳的引力也无法紧紧吸住它自己的大气层。热量以电粒子流的形式逃离太阳,流向地球,时速高达100万英里。这些粒子叫等离子体,来自太阳的等离子流叫太阳风。太阳活动越剧烈,太阳风越强烈”。依据第一段的内容来看,等离子体逃离太阳的原因不是因为太阳的引力太弱,而是因为太阳非常热,活动又极为剧烈,由此可见题干陈述的意义与短文内容不一致。所以答案为B。
    题干意为“地球相当安全,因为有磁场在高空包围着地球,将太阳风档在地球大气层外面”。利用题干中的细节信息词/短语the Earth, a magnetic field, attack by the solar wind作为定位线索,在第二段中找到相关句:The solar wind constantly streams toward the Earth,but don't worry because a protective magnetic field surrounds our planet(指地 球).The same magnetic field that makes your compass point north also steers the particles from the Sun to the north and south poles.The charged particles become trapped in magnetic belts around the Earth. When a large blast of solar wind crashes into the Earth's magnetic field,the magnetic field first gets squeezed and then the magnetic field lines break and recon-fleet.定位线索词集中出现在第二段第一句中,因此重点关注该句。该句提到“太阳风不断地流向地球,但是不必担心,因为有一个保护性的磁场包围着我们的地球”。显然该句意义与题干意义一致。所以答案为A。
    题干意为“有些科学家担心包围地球起防护作用的磁场有一天会消失”。利 用题干中的细节信息短语some scientists, possible disappearance of the Earth's protective magnetic field, in the future作为定位线索,结果发现disappearance of the Earth's protective magnetic field在短文中根本没有提到,some scientists在短文中也没有出现,由此可知一些科学家是否在担心包围地球起防护作用的磁场有一天会消失是短文中未提及的信息。所以答 案为C。
    题干意为“当电子落入地球两极的大气层中,并与大气层中的气体分子碰 撞时就形成了极光”。利用题干中的细节信息词/短语auroras, electrons, Earth's atmos-phere, poles, gas molecule作为定位线索,在第三段中找到相关句:The breaking and reconnecting of the magnetic field lines can cause atomic particles called electrons trapped in the belts to fall into the Earth's atmosphere at the poles.As the electrons fall to the Earth,they collide with gas molecules in the atmosphere,creating flashes of light in the sky. Each atmos- pheric gas glows a different color. Oxygen and nitrogen glows red and green and nitrogen glows violet-purple. As these various colors glow and dance in the night sky,they create the Northern Lights and the Southern Lights.定位线索词集中出现在第三段中,因此重点关注第三段。首先重点关注第三段的前两句。这两个句子说明“磁场磁力线的断开和闭合产生叫电子的原子粒子,该原子粒子会被截留在磁场中,并最终落入地球两极的大气层中。等离子流的电子进入地球,与大气层的气体分子发生碰撞,在天空中产生光芒”。接下来的句子提到 “每一种大气层的气体会产生不同颜色的光,氧和氮发红绿光,氮气发蓝紫光。当这些不同颜色的光在夜空中闪烁时就产生了北极光和南极光”。由此可见当等离子流的电子进入两极的大气层,并与大气层的气体分子发生碰撞时,就会产出极光。题干句表达的意思与短文介绍的极光成因相符,所以答案是A。
    题干意为“除非你在阿拉斯加州或是在加拿大,否则你看不见北极光”。利用题干中的细节信息词/短语Northern Lights, Alaska, Canada作为定位线索,在第四段中找 到相关句:Watching auroras (Northern Lights的近义词)is fun and exciting, but normally you can only see them in places far north like Alaska and Canada.The movement of the auro- ra across the sky is usually slow enough to easily follow with your eyes but they can also pul- sate,flicker,or even move like waves.During solar maximum,auroras are seen as far south as Florida, even Mexico!定位线索词集中在第四段中,因此重点关注这个段落,尤其是该段第一句。该句意为“看北极光很有趣也很令人兴奋,但是通常你只有在极北的地方,例如在阿 拉斯加州和加拿大才能看见极光”。但是接下来,该段最后一句还提到“在太阳风暴达到最高峰的期间,明亮的北极光甚至在位于极南面的佛罗里达州甚至墨西哥都能看到”,由此可见 并非只有在阿拉斯加州或是在加拿大才能看见北极光。所以题干陈述的信息与短文内容不一 致。因此答案为B。
    题干意为“每年都会有上万游客专程前往娜威和瑞典观赏北极光”。利用题 干中的细节信息词/短语tens of thousands of tourists, special trips, Norway, Sweden, every year, Northern Lights作为定位线索,结果发现短文中根本没有提到关于游客的信息,因此题干中陈述的信息为短文中未提及的信息。所以答案为C。
    题干意为“极光通常很接近地面,又长又厚”。利用题干中的细节信息词/短语aurora , ground作为定位线索,在短文中寻找相关句,同时因为题千中出现了修饰词 long , thick,也关注这两个修饰词在短文中的出现情况,这样在第五段中找到相关句:Auro- ras often seem to be very close to the ground,but the lowest aurora is still about 100 kilome- ters above the ground,a distance much higher than clouds are f

  • 第4题:

    资料:When we see well,we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
    People who are near-sighted can only see things that are very close to their eyes,Everything else seems blurry(=unclear).Many people who do a lot of work,such as writing,reading and sewing become near-sighted.
    People who are far-sighted suffer from just the opposite problem. They can see things that are far away,but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading,they must get glasses,too.
    Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This,too,can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now,however,it is possible to operate on the cataracts and remove them.
    Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself,look at an object out of one eye;Then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.

    When things far away seem indistinct, one is probably______.

    A.astigmatic
    B.far-sighted
    C.suffering from cataracts
    D.near-sighted

    答案:D
    解析:
    本题考查的是细节理解。
    【关键词】things far away;indistinct
    【主题句】第2自然段People who are near-sighted can only see things that are very close to their eyes,Everything else seems blurry(=unclear). 近视的人只能看到非常接近他们眼睛的东西,其他一切看起来都很模糊(=不清楚)。
    【解析】本题的问题是“当远处的东西看起来模糊不清时,可能就是?”A选项“散光”;B选项“远视”;C选项“患有白内障”;D选项“近视”。根据主题句,看不清远方的东西,应当是患有近视,故D选项正确。

At the same time,a tiny radio re-ceiver linked to the computer goes to work.It picks up signals from navigation satellites such as the NAVSTAR network.Using these signals,the computer shows the car's position at all times and displays this position on the map.The computer can also calculate and display the best route to follow.
    A navigation computer may also receive and use data about road construction,weather condi-tions,and traffic jams. This information would be displayed to the driver and the computer would also use the information to work out alternate(交替的)routes.
    Most cars nowadays also contain computers that help cars run more efficiently. Microproces- sors(微处理机)control certain engine functions by regulating the mixing of fuel. Data on car speed,oil pressure,revolutions per minute,engine temperature,and fuel level can be displayed as digital data(numbers)or warning lights.
    Some auto designers suggest that a central computer display be used to clearly present such timely information as car speed and fuel level.Warning lights would indicate a drop in oil pressure or a sudden rise in engine temperature.To get more information on these conditions,the driver could call it up on the computer display screen.When needed,the computer could be “asked”to provide navigation aid or information about the car's condition.

    Of the following functions,which is NOT possessed by the navigation computer?
    A: Showing a map of the region a driver plans to drive through.
    B: Predicting a car crash on the road.
    C: Getting information about road constnzction,weather conditions,and traffic jams.
    D: Showing the car's position at all times and displaying it on the map.

    答案:B
    解析:
    文章第二段描述了一位司机迷路的情况,紧接着第三段讲到,当汽车上装载了计算机导航系统后,会给司机到来很大的方便。很明显,答案为选项C。


    本题属于词汇题,问“navigate”在第三段中的意思是什么?navigate的本意是“导航”,即选项C的意思,但在文中,它指的不是给轮船导航,而是为汽车导航,为驾驶员指路,故选项B为正确答案。


    本题是根据第四段中间这两句话出的问题“These computers vary in detail. But they all contain series of maps on videodiscs or videotapes.”所有(车载)计算机导航系统都含有电子地图,即保存在视盘或录像带上的地图(series of maps on videodiscs or videotapes)所以A为正确答案。


    本题问的是当车载计算机收不到来自导航卫星的信号时会出现什么情况。根据常识可以判断,计算机无法确定汽车的位置。此题可以通过第五段中的“Using these signals,the computer shows the car's position at all times and displays this position on the map.”推断出来,本题是此句意思的反说。


    选项中给出了计算机导航系统的几个功能,问其中哪项不是。通过阅读短文,我们发现选项B的信息文中没有提到,故此题选B。

    The Northern Lights
    The Sun is stormy and has its own kind of weather It is so hot and active that even the Sun's gravity cannot hold its atmosphere in check!Energy flows away from the Sun toward the Earth in a stream of electrified particles that move at speeds around a million miles per hour. These particles are called plasma,and the stream of plasma coming from the Sun is called the solar wind. The more active the Sun,the stronger the solar wind.
    The solar wind constantly streams toward the Earth,but don't worry because a protective magnetic field surrounds our planet.The same magnetic field that makes your compass point north also steers the particles from the Sun to the north and south poles.The charged particles become trapped in magnetic belts around the Earth. When a large blast of solar wind crashes into the Earth's magnetic field,the magnetic field first gets squeezed and then the magnetic field lines break and reconnect.
    The breaking and reconnecting of the magnetic field lines can cause atomic particles called electrons trapped in the belts to fall into the Earth's atmosphere at the poles. As the electrons fall to the Earth,they collide with gas molecules in the atmosphere,creating flashes of light in the sky. Each atmospheric gas glows a different color. Oxygen and nitrogen glows red and green and nitrogen glows violet-purple. As these various colors glow and dance in the night sky,they create the Northern Lights and the Southern Lights.
    Watching auroras is fun and exciting,but normally you can only see them in places far north like Alaska and Canada. The movement of the aurora across the sky is usually slow enough to easily follow with your eyes but they can also pulsate,flicker,or even move like waves.During solar maximum,auroras are seen as far south as Florida,even Mexico!
    Auroras often seem to be very close to the ground,but the lowest aurora is still about 100 kilometers above the ground,a distance much higher than clouds are formed or airplanes can fly. A typical aurora band can be thousands of kilometers long,a few hundred kilometers high,but only a few hundred meters thick.
    We hope you are able to travel to far north places like the Arctic Circle and see the Northern Lights at least once during your lifetime. We know you will never forget it!

    You cannot see the Northern Lights unless you are in Alaska or Canada.
    A: Right
    B: Wrong
    C: Not mentioned

    答案:B
    解析:
    题干意为“太阳的引力太弱,等离子体逃离太阳,流向地球”。利用题干中的细节信息词/短语the Sun's gravity, plasma, Earth作为定位线索,在第一段中找到相关句: The Sun is stormy and has its own kind of weather. It is so hot and active that even the Sun's gravity cannot hold its atmosphere in check!Energy flows away from the Sun toward the Earth in a stream of electrified particles that move at speeds around a million miles per hour. These particles are called plasma,and the stream of plasma coming from the Sun is called the solar wind. The more active the Sun, the stronger the solar wind.定位线索词集中出现在第一段中,因此重点关注第一段。第一段意为“太阳是多风暴的,有它自己独特的气候。太阳非常热,而且活动又极为剧烈,以至于太阳的引力也无法紧紧吸住它自己的大气层。热量以电粒子流的形式逃离太阳,流向地球,时速高达100万英里。这些粒子叫等离子体,来自太阳的等离子流叫太阳风。太阳活动越剧烈,太阳风越强烈”。依据第一段的内容来看,等离子体逃离太阳的原因不是因为太阳的引力太弱,而是因为太阳非常热,活动又极为剧烈,由此可见题干陈述的意义与短文内容不一致。所以答案为B。
    题干意为“地球相当安全,因为有磁场在高空包围着地球,将太阳风档在地球大气层外面”。利用题干中的细节信息词/短语the Earth, a magnetic field, attack by the solar wind作为定位线索,在第二段中找到相关句:The solar wind constantly streams toward the Earth,but don't worry because a protective magnetic field surrounds our planet(指地 球).The same magnetic field that makes your compass point north also steers the particles from the Sun to the north and south poles.The charged particles become trapped in magnetic belts around the Earth. When a large blast of solar wind crashes into the Earth's magnetic field,the magnetic field first gets squeezed and then the magnetic field lines break and recon-fleet.定位线索词集中出现在第二段第一句中,因此重点关注该句。该句提到“太阳风不断地流向地球,但是不必担心,因为有一个保护性的磁场包围着我们的地球”。显然该句意义与题干意义一致。所以答案为A。
    题干意为“有些科学家担心包围地球起防护作用的磁场有一天会消失”。利 用题干中的细节信息短语some scientists, possible disappearance of the Earth's protective magnetic field, in the future作为定位线索,结果发现disappearance of the Earth's protective magnetic field在短文中根本没有提到,some scientists在短文中也没有出现,由此可知一些科学家是否在担心包围地球起防护作用的磁场有一天会消失是短文中未提及的信息。所以答 案为C。
    题干意为“当电子落入地球两极的大气层中,并与大气层中的气体分子碰 撞时就形成了极光”。利用题干中的细节信息词/短语auroras, electrons, Earth's atmos-phere, poles, gas molecule作为定位线索,在第三段中找到相关句:The breaking and reconnecting of the magnetic field lines can cause atomic particles called electrons trapped in the belts to fall into the Earth's atmosphere at the poles.As the electrons fall to the Earth,they collide with gas molecules in the atmosphere,creating flashes of light in the sky. Each atmos- pheric gas glows a different color. Oxygen and nitrogen glows red and green and nitrogen glows violet-purple. As these various colors glow and dance in the night sky,they create the Northern Lights and the Southern Lights.定位线索词集中出现在第三段中,因此重点关注第三段。首先重点关注第三段的前两句。这两个句子说明“磁场磁力线的断开和闭合产生叫电子的原子粒子,该原子粒子会被截留在磁场中,并最终落入地球两极的大气层中。等离子流的电子进入地球,与大气层的气体分子发生碰撞,在天空中产生光芒”。接下来的句子提到 “每一种大气层的气体会产生不同颜色的光,氧和氮发红绿光,氮气发蓝紫光。当这些不同颜色的光在夜空中闪烁时就产生了北极光和南极光”。由此可见当等离子流的电子进入两极的大气层,并与大气层的气体分子发生碰撞时,就会产出极光。题干句表达的意思与短文介绍的极光成因相符,所以答案是A。
    题干意为“除非你在阿拉斯加州或是在加拿大,否则你看不见北极光”。利用题干中的细节信息词/短语Northern Lights, Alaska, Canada作为定位线索,在第四段中找 到相关句:Watching auroras (Northern Lights的近义词)is fun and exciting, but normally you can only see them in places far north like Alaska and Canada.The movement of the auro- ra across the sky is usually slow enough to easily follow with your eyes but they can also pul- sate,flicker,or even move like waves.During solar maximum,auroras are seen as far south as Florida, even Mexico!定位线索词集中在第四段中,因此重点关注这个段落,尤其是该段第一句。该句意为“看北极光很有趣也很令人兴奋,但是通常你只有在极北的地方,例如在阿 拉斯加州和加拿大才能看见极光”。但是接下来,该段最后一句还提到“在太阳风暴达到最高峰的期间,明亮的北极光甚至在位于极南面的佛罗里达州甚至墨西哥都能看到”,由此可见 并非只有在阿拉斯加州或是在加拿大才能看见北极光。所以题干陈述的信息与短文内容不一 致。因此答案为B。
    题干意为“每年都会有上万游客专程前往娜威和瑞典观赏北极光”。利用题 干中的细节信息词/短语tens of thousands of tourists, special trips, Norway, Sweden, every year, Northern Lights作为定位线索,结果发现短文中根本没有提到关于游客的信息,因此题干中陈述的信息为短文中未提及的信息。所以答案为C。
    题干意为“极光通常很接近地面,又长又厚”。利用题干中的细节信息词/短语aurora , ground作为定位线索,在短文中寻找相关句,同时因为题千中出现了修饰词 long , thick,也关注这两个修饰词在短文中的出现情况,这样在第五段中找到相关句:Auro- ras often seem to be very close to the ground,but the lowest aurora is still about 100 kilome- ters above the ground,a distance much higher than clouds are f

    文章第二段描述了一位司机迷路的情况,紧接着第三段讲到,当汽车上装载了计算机导航系统后,会给司机到来很大的方便。很明显,答案为选项C。


    本题属于词汇题,问“navigate”在第三段中的意思是什么?navigate的本意是“导航”,即选项C的意思,但在文中,它指的不是给轮船导航,而是为汽车导航,为驾驶员指路,故选项B为正确答案。


    本题是根据第四段中间这两句话出的问题“These computers vary in detail. But they all contain series of maps on videodiscs or videotapes.”所有(车载)计算机导航系统都含有电子地图,即保存在视盘或录像带上的地图(series of maps on videodiscs or videotapes)所以A为正确答案。


    本题问的是当车载计算机收不到来自导航卫星的信号时会出现什么情况。根据常识可以判断,计算机无法确定汽车的位置。此题可以通过第五段中的“Using these signals,the computer shows the car's position at all times and displays this position on the map.”推断出来,本题是此句意思的反说。


    选项中给出了计算机导航系统的几个功能,问其中哪项不是。通过阅读短文,我们发现选项B的信息文中没有提到,故此题选B。
