听力原文： Cities try to improve their transportation in order for cars, buses and trucks to travel easily on them. Large highways run through cities, so people can travel from their home to their job quickly. Also, cities have installed traffic lights to control the vehicles on the highways. Two cities experimented with public buses to reduce the number of automobiles on that street. In Rome, passengers on city buses did not have to pay for a bus ticket. In Stockholm, people paid a low price for a one-year ticket to travel on any bus, trolley car or train in the city. Finally, to increase the safety of people who walk, many cities have closed some streets to vehicles.

听力原文： The very success of satellite communications systems has raised widespread concern about their future. Some countries are already using satellites for domestic communications in place of conventional telephone lines on land. Although this technique is extremely useful for linking widely scattered villages in remote or mountainous regions, in heavily built-up areas where extensive telephone and telegraph systems already exist, domestic satellites are seen by the land-line networks as unfair competition. Despite such opposition, domestic satellites are gaining support from many businesses and public interest groups in the United States and seem likely to be more widely utilized in the future.
