Universal Studios Hollywood, a park for fun, entertainment, and even learning, is taking its first steps in a 25-year plan to expand itself. The plan is to expand the amusement facilities (设施) and develop a residential (住宅的) neighborhood in the area. "I’m really excited about what’s happening here," one visitor said.

Originally known as Universal City, Universal Studios Hollywood was founded in 1915 by Carl Laemmle. It was the first studio offering tours during which people could watch films in production. Since then, Universal Studios Hollywood has grown to include theme parks, restaurants, hotels, shopping malls, and etc. This park proved to be so popular that Universal Studios Florida opened in 1990.

With such past success and growth, it’s no wonder that Universal Studios Hollywood is excited about its latest plans for expansion. The original plans had to be changed because of environmental regulations (规章), but now they are ready to move ahead at full speed.

While many new attractions are in the works for the new expansion, Universal Studios Hollywood will keep some of its old attractions, such as the Bates Mansion from the film Psychoand the Shark from Jaws. These attractions offer a look at the historical development of the film industry, and show the advances in film-production techniques over the years. But while preserving the past, plenty of new high-tech sound stages, rides, and theaters are in the works. In May, Citywalk, a shopping, dining, and entertainment facility, began undergoing renovations (整修), and spring also saw the opening of Sky Venture Hollywood, an attraction where visitors can float 40 feet into the air on 125 mph winds.

小题1:As a result of the popularity of Universal Studios Hollywood, ______.

A.other parks were opened

B.homeowners lost their houses

C.Carl Laemmle decided to produce films

D.more environmental regulations have been made小题2:The visitor in the first paragraph holds a(n) _________ attitude towards the expansion.

A.supportive

B.doubtful

C.objective

D.Negative小题3:Why will Universal Studios Hollywood preserve some old attractions?

A.They’re too costly to replace.

B.They show the history of the film industry.

C.They’re more popular than others.

D.They are more beautiful than the new ones.小题4:From the passage we learn that Universal Studios Hollywood ____.
