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 envision 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(吵杂狂乱的喧闹)-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(散开) 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(??55,725), is as quiet as a motorcycle and as simple to operate as a car.
Although it would not have any road-driving capabilities, it would bring this form of travel within the grasp of a wider section of people. The new technology would automate many of the pilot’s functions. This Small Aircraft Transportation System(Sats) would divert pressure away from the “hub-and-spoke(中心辐射型)” model of air travel. Hub-and-spoke refers to the typically US model of passengers being processed through large “hub” airports and then on to secondary flights to “spoke” airports near their final destinations.

As is known to all, colors appear in every language to express people’s feeling and thoughts. Then, what is the situation in American English?
Red is a hot color. Americans may say they are red hot about something unfair. They are red hot when they are very angry about something. The small hot-tasting peppers found in many Mexican foods are called red hot for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland Jazz.
Pink is a lighter kind of red. People sometimes say they are in the pink when they are in good health. The expression was first used in America at the beginning of the twentieth century. It comes from the fact that many babies are born with nice pink skin that shows that they are in good health.
The color black is often used in expressions. People describe a day on which everything goes wrong as a black day. People or things on a blacklist are connected with things illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.
The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick feeling in his stomach may say he feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.
Sometimes a person may be upset because he does not have something as nice as a friend has. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because green is the color of the back side of the paper money.
Americans use “red hot” to describe the following EXCEPT _______.
A. something unfair B. small hot-tasting peppers
C. the person who is very angry D. popular music like Dixieland Jazz
When we say someone feels a little green, it means he/she _______.
A. enjoys himself in boating B. is hit by a high wave
C. has a stomachache D. likes trees and grass
In the writer’s eyes, what is related to a black day?

To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your students, you must be __1__-speaking, with a good, strong,__2__voice which is fully under your control; and you must be able to __3__what you are teaching, in order to make its meaning clear.
__4__a good teacher, and you will see that he does not sit still before his class; he __5__the whole time he is teaching; he walks about, using his__6__, hands and fingers to help him in his explanations, and his face to express his__7__. Listen to him, and you will__8__the loudness, the quality and the musical note of his voice always __9__according to what he is talking about. The fact that a good teacher has some of the gifts of a good actor doesn't __10__that he will indeed be able to act well on the stage, for there are very important__11__between the teacher's work and the actor's. The__12__has to speak words which he has learnt by heart; he has to repeat exactly the__13__words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually__14__beforehand. What he has to do is to make all these carefully learnt words and actions seem __15__on the stage.
A good teacher__16__in quite a different way. His students take an active part in his __17__: they ask and answer questions, they obey orders, and if they don't __18__something, they will say no. The teacher therefore has to suit his act to the needs of his students, which is in his class. He cannot learn his part by heart, but must __19__it as he goes along.
I have known many teachers who were fine__20__in class but unable to take part in a stage play because their brains wouldn't keep discipline: they could not keep strictly to what another had written.
