A Frenchman had arrived at a small Italian town and was staying with his wife at the best hotel there. One night he went out for a walk alone. He was late and the small street was dark and lonely. Suddenly he heard footsteps behind him. He turned his head and saw an Italian young man who quickly walked past him. The man was nearly out of sight when the Frenchman suddenly found that his watch was gone. He thought that it was the Italian who had taken his watch. He decided to follow him and force him to return the watch. Soon the Frenchman caught up with the Italian. Neither of them understood the other’s language.

There was once a large ,fat

Without proper
planning, tourism can cause problems. For example, too many tourists can crowd
public places that are also enjoyed by the people of a country. If tourists
create too much traffic, the local people become unhappy. They begin to dislike
tourists and to treat them impolitely. They forget how much tourism can help
the country's economy(經(jīng)濟(jì)). It is important to think
about the people of a destination（目的地）country and how
tourism affects them. Tourism should help a country keep the customs and beauty
that attract tourists. Tourism should also advance the well-being（health and happiness）of local people.
Too much tourism can
be a problem. If tourism grows too quickly, people leave other jobs to work in
the tourism industry. This means that other parts of the country's economy can
suffer.
On the other hand, if
there is not enough tourism, people can lose jobs. Businesses can also lose
money. It costs a great deal of money to build large hotels, airports, air
terminals, first-class roads, and other support facilities（設(shè)施）needed by tourist attractions. For example, a major
international-class tourism hotel can cost as much as 50 thousand dollars per
room to build. If this room is not used most of the time, the owners of the
hotel lose money.
Building a hotel is
just a beginning. There must be many support facilities(設(shè)施) as well, including roads to get to the hotel, electricity,
sewers（陰溝）to handle waste, and water. All of these
cost money. If they are not used because there are not enough tourists, jobs
and money are lost.
71. Which of the following has most probably been discussed in
the paragraph that goes before the passage?
A. It is extremely important to
develop tourism.
B. Building roads and hotels is
necessary.
C. Support facilities are highly
necessary.
D. Planning is of great importance
to tourism.
72. Too much tourism can cause all these problems EXCEPT __________.
A. a bad impact on other industries
B. a change of tourists' customs(風(fēng)俗)
C. over-crowdedness of places of
interest
D. pressure on traffic
73. Not enough tourism can lead to ___________.
A. a rise of all the
goods.
B. a rise in tourist attractions
C. an increase of employment
D. an increase of unemployment
74. It is good for local people to be well aware (意識(shí))that tourism will _______________.
A. use up a large amount of water
B. weaken their economy
C. help establish their traditions
D. help improve their life
D
A young lady who was fond of Shakespeare visited Stratford-on-Avon
and liked everything she saw there. When she reached the railway station, she
looked round and cried, "Ho, I think I like this most of all! Here the
great master must have come to take the train to
75. The passage is a ___________.
A. puzzle B. short story C. joke D. play
