As motorways become more and more blocked up with traffic, a new generation on flying cars will be needed to ferry people along skyways. That is the conclusion of engineers from the US space agency and aeronautical firms, who _ future commuters traveling by "skycar". These could look much like the concept skycar shown in the picture, designed by Boeing research and development. However, such vehicles could be some 25 years from appearing on the market. Efforts to build flying vehicles in the past have not been very successful. Such vehicles would not only be expensive and require the skills of a trained pilot to fly, but there are significant engineering challenges involved in developing them. "When you try to combine them you get the worst of both worlds: a very heavy, slow, expensive vehicle that's hard to use," said Mark Moore, head of the personal air vehicle(PAV) division of the vehicle systems program at Nasa's Langley Research Center in Hampton, US. But Boeing is also considering how to police the airways and prevent total pandemonium -if thousands of flying cars enter the skies. "The neat, gee-whiz part is thinking about what the vehicle itself would look like," said Dick Paul, a vice president with Phantom Works, Boeing's research and development arm. "But we're trying to think through all the consequences of what it would take to deploy a fleet of these." Past proposals to solve this problem have included artificial intelligence systems to prevent collisions between air traffic. Nasa is working on flying vehicles with the initial goal of transforming small plane travel. Small planes are generally costly, loud, and require months of training and lots of money to operate, making flying to work impractical for most people. But within five years, Nasa researchers hope to develop technology for a small plane that can fly out of regional airports, costs less than $100,000(PS55,725), is as quiet as a motorcycle and as simple to operate as a car. Although it would not have any road-driving capabilities, it... The best title for this text would be _ .

Speaking in public is most people's least favorite thing. The reason is that we're all afraid of making fools of ourselves. The more important the speech is the more frightened we become. But stop biting your finger-nails. Public speaking is easy. It's just plain talking, and you talk all the time. Public speaking is not a "gift" like musical talent or being able to draw. Anybody who can talk can speak in public. Here are some tips: Keep it simple. Your audience is going to learn one or two from your main ideas by heart. If you can't express, then your speech is not focused well enough. And if you don't have a clear idea of what you want to say, then your audience will have no interest in your speech. Get organized. No matter how long or short your speech is, you'd better get your materials in order: how you're going to start, what major points you want to make and how you're going to close. You may often write the last sentence first. When you know what your aim is, you can choose any ways to get there. A strong close is powerful. The last thing you say is what your audience will most likely remember. Keep it short. The standard length of a vaudeville act was 12 minutes. If all those troupers want to sing and dance, they may make the audience bored. So make your speech short. Which of the statements is TRUE according to the passage? A) The more important the speech is, the easier it is. B) Anybody who can talk is not frightened of public speaking. C) The standard length of a speech is 12 minutes. D) Public speaking is easy. Have a go, and you will make it.

Ques: Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to an outlet that is acceptable in the domestic setting. One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn't solve all behavior problems, but it is the foundation for solving just about any problem. Training pens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of "come here, sit," it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack by using extreme measure. You can teach your dog its subordinate role by teaching it to show submission to you. Most dogs love performing tricks for you to pleasantly accept that you are in charge. Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal. When a dog has received effective obedience training, its owner _ . A) can give the dog more freedom B) will enjoy a better family life C) can give the dog more rewards D) will have more confidence in himself
