参考解析
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，会给司机带来很大的方便。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。
本题问题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。

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. If someone attacks you - remember your safety is more important than your property.1). This passage mainly focuses on ().2). If you want to guarantee your safety at home, you should ().3).

When youre 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.

共用题干The Northern LightsThe 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: RightB: WrongC: Not mentioned

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.astigmaticB.far-sightedC.suffering from cataractsD.near-sighted

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 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. Without signals from navigation satellites,the in-car computer______.A: would still be able to locate the. car's position at all timesB: would fail to locate the car's positionC: could still work out the best route to followD: would seek help from the radio receiver linked to it
