答案

小题1:C

小题2:D

小题3:B

小题1:飞机装配对劳动力的素质要求较高；沈阳飞机制造公司、成都飞机制造公司、西安飞机制造公司和南昌飞机制造公司是我国的四大飞机制造公司。

小题2:我国生产ARJ21支线飞机属于零配件装配；飞机零配件的分散生产，主要是为了发挥不同地区的优势，尽可能降低生产成本。

小题3:在土地、税收等方面给予政策优惠可以降低生产成本，但并不会提高我国飞机制造业产品的核心竞争力；不断拓展国际和国内航线能提供广阔的市场空间，但对飞机制造业产品的市场竞争力的提高并无影响；限制波音、空中客车等国外产品进入我国市场，与世界经济全球化的趋势相违背，而且贸易保护也不一定能提高我国飞机制造业产品的市场竞争力。

As with any work of art, the merit of Chapman Kelley’s "Wildflower Works I" was in the eye of the beholder.
Kelley, who normally works with paint and canvas, considered the twin oval gardens planted in 1984 at Daley Bicentennial Park his most important piece.
The Chicago Park District considered it a patch of raggedy vegetation on public property that could be dug up and replanted at will like the flower boxes along Michigan Avenue. And that’s what happened in June 2004, when the district decided to create a more orderly vista for pedestrians crossing from Millennium Park via the new Frank Gehry footbridge.
If you’re looking for evidence that the rubes who run the Park District don’t know art when they see it, all you have to do is visit what’s left of Kelley’s masterpiece. The exuberant 1.5-acre tangle of leggy wildflowers is now confined to a tidy rectangle, restrained on all sides by a knee-high hedge and surrounded by a closely cropped lawn. White hydrangeas and pink shrub roses complete the look. We don’t know who’s responsible for the redesign, but We’ll bet the carpet in his home doesn’t go with the furniture.
Still, you’d think the Park District Was within its rights to plow under the prairie. Wrong. Kelley just won at lawsuit in which he argued that the garden was public are and therefore protected by the federal Visual Artists Rights Act. Under that law, the district should have given him 90 days’ notice that it intended to mess with his artwork instead of rushing headlong into the demolition, a la Meigs Field. That way Kelley could have mounted a legal challenge, or at least removed the plants.
Park District officials said they never considered the garden a work of art, even though it was installed by an established artist and not, say, Joe’s Sod and Landscaping. We can understand their confusion. Just recently, we figured out that the caged greenery directly south of Pritzker Pavilion is supposed to be an architectural statement and not a Christmas tree lot.
All that’s left is for the district to compensate Kelley for his loss. Whatever price the parties settle on, let’s hope the agreement also provides for the removal of the rest of "Wildflower Works I. " If it was’t an eyesore before—and plenty of people thought it was... it sure is now.

The word "mess with" underlined in Paragraph 5 most likely means ______.

A．disturb

B．confuse

C．mess up

D．muddle
