botanical artist interested in scientific illustration rather than being the subjects of fine art. Early in the nineteenth century, however, the Peale family of Philadelphia established the still life, a pictureconsisting mainly of inanimate (5) objects, as a valuable part of the artist's repertoire. The fruit paintings by James and Sarah Miriam Peale are simple arrangements of a few objects, handsomely colored, small in size, and representing little more than what they are. In contrast were the highly symbolic, complex compositions by Charles Bird King, with their biting satire and critical social commentary. Each of these strains comminuted into and (10)well past mid-century. John F. Francis (1808-86) was a part of the Pennsylvania still-life tradition that arose, at least in part, from the work of the Peales. Most of his still lifes date from around 1850 to 1875. Luncheon Still Life looks like one of the Peales' pieces on a larger scale, kits greater complexity resulting from the number of objects. It is also (15)indebted to the luncheon type of still life found in seventeenth-century Dutch painting. The opened bottles of wine and the glasses of wine partially consumed suggest a number of unseen guests. The appeal of the fruit and nuts to our sense of taste is heightened by the juicy orange, which has already been sliced. The arrangement is additive, that is, made up of many different parts, not always (20)compositionally integrated, with all objects of essentially equal importance. About 1848, Severin Roesen came to the United States from Germany and settled in New York City, where he began to paint large, lush still lifes of flowers, fruit, or both, often measuring over four feet across. Still Life with Fruit and Champagne is typical in its brilliance of color, meticulous rendering of detail, (25)compact composition, and unabashed abundance. Rich in symbolic overtones, the beautifully painted objects carry additional meanings ...... butterflies or fallen buds suggest the impermanence of life, a bird's nest with eggs means fertility, and so on. Above all, Roesen's art expresses the abundance that America symbolized to many of its citizens. What does the passage mainly discuss？ A．The artwork of James and Sarah Miriam Peale B．How Philadelphia became a center for art in the nineteenth century C．Nineteenth-century still-life paintings in the United States D．How botanical art inspired the first still-life paintings

These phones and their related tracking services allow parents to pinpoint the location of their children with ease. Parents agree to pick up the phone bill in return for the reassurance of knowing where their children are; children are prepared to put up with the watching if they are allowed to have a phone. Mobile operators in America are now launching tracking services. Under a federal decree known as E911, they had to upgrade their networks to ensure that anyone dialing the 911 emergency number could be located to within 100 metres. Some operators opted for triangulation technology, which determines the location of the handset by comparing the signals received by different base stations. But Verizon and Sprint chose to adopt the more expensive but more accurate GPS technology instead, and are now looking for ways to make money from it. Verizon calls its service "Chaperone". For $10 a month, parents can call up the location of their child's LG Migo handset from their own mobile phones, or from a PC. The child receives a message saying that the handset's position has been requested, and the parents receive an ad dress, or a marker on a web-based map, giving the child's location. For an extra $10 per month, they can sign up for Child Zone, a service that, among other things, fires off an alert when a youngster (or, at least, the youngster's handset) strays outside a specified area. For its part, Sprint has launched a similar service that can also let parents know when a child arrives at a particular location. Another location service is available from Nextel, a mobile operator that was taken over by Sprint in 2005. Nextel opened up some of its systems to enable other firms to build their own software and services on top of its GPS technology. One example is AccuTracking, a small company which offers a tracking service for $6 a month and boasts that it is "ideal for vehicle tracking" or to keep "virtual eyes on kids". Some customers are also using the service to track their spouses, by hiding phones in their cars. "Mine is hidden under the hood, hot-wired to the battery—it works very well and it is easy to hook up continuous power, "writes one customer on AccuTracking's message board. Start-ups are working on everything from city-wide games of hide-and-seek to monitoring the locations of Alzheimer's patients. Services that monitor jogging routes, and work out distance travelled and calories consumed, might also prove popular. As a result, mobile operators, handset-makers and start-ups could transform. and expand a small, specialist market so far dominated by expensive, dedicated tracking systems. The tracking function of the mobile networks was probably first intended for ______. A．federal officials B．national security C．parent consumers D．emergency rescue
