All but the tiniest of roads have to have names so they can be recognized on a map, and so people can ask directions to them. Americans name a lot of bridges, too.
Very often these names carry a clear geographical reference the Pennsylvania Turnpike, for example. Or,like the George Washington Bridge, roads and bridges are named for famous historical figures or powerful officers. We make a big deal out of naming things, as when someone decided to name an airport after a U. S. judge.
So now we have the Baltimore Washington International Thurgood Marshall Airport. Many,if not most, of our college buildings are named for wealthy people who gave a lot of money to the schools. And our sports centers took this idea a step further. Companies paid a whole lot of money for what′s called the "naming rights" to U. S. Cellular Field in Chicago, for example, and Citizens Bank Park in Philadelphia.
Now the governor(州长) of Virginia, Bob McDonnell,wants to sell naming rights to roads and bridges in the state. He says not just companies, but also wealthy people, would help the Virginia transportation budget(预算) by paying to have their names--or perhaps those of loved ones--placed on roads and bridges, and thus on maps as well. People hold different views, however. Supporters say Americans are used to having things sponsored(赞助). Others disagree, considering the idea as the next step in the "companies of America. " They wonder how far such an idea might spread, and where it would end:at the Burger King Pacific Ocean, perhaps.
Most of the roads need to have names so that____.
A.they can remind people of the past
B.people can learn about them better
C.they can be easily recognized on mapss
D.people can enjoy naming them
Who are many college buildings named for according to the passage？A.Powerful officers.

C.Everything is named by an American company.
D.Pacific Ocean will be rename
Why does the governor of Virginia want to sell naming rights？A.To remember the loved names.
B.To make the state well-known.
C.To help the transportation budget.

Although trains were a popular means of travel for some time, automobiles slowly began to take their place. Automobile travel caused problems for city hotels, which did not have enough parking space for so many cars.
People who traveled by automobile needed a different kind of hotel. They needed places to stay that were near highways and had room to park. Motorists did not like to drive in heavy city traffic to reach a hotel. The answer to the motorists' problems came when a new kind of hotel was built. These new buildings were called motels, a word made from the first part of MOTORIST and the last part of HOTELS.
Motels were much smaller than hotels. Built on ground level, often in separate units, they were more convenient for people traveling. The separate units also made them quieter than hotels, best of all, there was more than enough room for cars to park. ,
Now, many big hotels in the cities are being torn down. They can no longer make enough money to stay in business. In their place, many small motels have been built on the outskirts(近郊) of cities. Motels have become a big business in the United States.
The first hotels were built______.
A．with hundreds of rooms
B．around the city centers
C．near railway stations
D．quite close to roads.
A.it was man’s first real invention
B.all transportation depends on it
C.every machine depends on it
D.both B and C
