There are some good ideas to reduce the use of private cars. In 1989, for example, the authorities in Rome began an interesting experiment: passengers on the city buses did not have to pay for their tickets.
In Stockholm there was another experiment: people paid very little for a season ticket to travel on any bus, trolley bus, train or tram in all the city.
In many cities now some streets are closed to vehicles, and pedestrians are safe there.
In London there is another experiment: part of the street is for buses only, so the buses can travel fast. There are no cars or taxies in front of them.
What the writer worries about in a big city is ______.
A．the number of traffic lights
B．the shortage of buses
C．the lack of motorways
D．the traffic congestion

Traffic Jams——No End in Sight
(1) Traffic congestion (拥堵) affects people throughout the world. Traffic jams cause smog in dozens of cities across both the developed and developing world. In the U. S., commuters (通勤人员 ) spend an average of a full working week each year sitting in traffic jams, according to the Texas Transportation Institute. While alternative ways of getting around are available, most people still choose their cars because they are looking for convenience, comfort and privacy.＜br＞
(2) The most promising technique for reducing city traffic is called congestion pricing, whereby cities charge a toll to enter certain parts of town at certain times of day. In theory, if the toll is high enough, some drivers will cancel their trips or go by bus or train. And in practice it seems to work: Singapore, London and Stockholm have reduced traffic and pollution in city centres thanks to congestion pricing.＜br＞
(3) Another way to reduce rush-hour traffic is for employers to implement flextime, which lets employees travel to and from work at off-peak traffic times to avoid the rush hour. Those who have to travel during busy times can do their part by sharing cars. Employers can also allow more staff to telecommute (work from home) so as to keep more cars off the road altogether.＜br＞
(4) Some urban planners still believe that the best way to ease traffic congestion is to build more roads, especially roads that can take drivers around or over crowded city streets. But such techniques do not really keep cars off the road; they only accommodate more of them.＜br＞
(5) Other, more forward-thinking, planners know that more and more drivers and cars are taking to the roads every day, and they are unwilling to encourage more private automobiles when public transport is so much better both for people and the environment. For this reason, the American government has decided to spend some $7 billion on helping to increase capacity on public-transportsystemsandupgradethemwithmoreefficienttechnologies.But＜br＞
environmentalists complain that such funding is tiny compared with the $50 billion being spent on roads and bridges.

Read carefully the following excerpt and then write your response in NO LESS THAN 200 words, in which you should: ●summarize the main message of the excerpt, and then ●comment on whether our brains will get lazy in a world run by intelligent machines. You can support yourself with information from the excerpt. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. With intelligent machines to do the thinking, will our brains get lazy？ Changing technology stimulates the brain and increases intelligence. But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent？ Artificial intelligence is taking over many human jobs. For instance, planes are being flown much of the time by automatic pilots. And the complex problem of controlling air traffic around large modern airports is also achieved by artificial intelligence that operates well beyond the capacity of mere human air traffic controllers. As machines get smarter, they will do more of our thinking for us and make life easier. In the future, the electronic assistant will develop to the point that it serves similar functions as a real living butler, fulfilling requests such as: “Organize a dinner party for six on Thursday, Jeeves, and invite the usual guests.” At that point, our long struggle with challenging technologies is at an end. Like Be Wooster, we can take it easy knowing that the hard work of planning and organizing is being done by a better brain-the electronic assistant. Starved of mental effort, our brains will regress.
The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.
Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion(拥挤). One proposed solution to this problem is the automated highway system.
When the auto enters the highway system, a retractable(可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements.
The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wak for the buzzer(蜂鸣器) that will warn of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,400 to 2,000 vehicles that can be carried by a present-day highway.

A．its power source
B．its driving system
