单选题The following two questions refer to the following passage: A prestigious private high school has made available to local families a tuition prepayment plan to ease the burden of paying the school's hefty tuition when a student matriculates. The plan allows parents of children under three years old to reserve a spot for their child at the school by making a payment of one-fourth of the current annual tuition for the high school. The parents then make an identical payment every year for the next 15 years, and the student's full four-year tuition is considered paid in full, regardless of how much the regular tuition payments have risen in the intervening years.

单选题Education is all enormous and expensive part of American life. Its size is matched by its variety.
Differences in American schools compared with those found in the majority of other countries lie in the fact that education here has long been intended for everyone—not just for a privileged elite. Schools are expected to meet the needs of every child, regardless of ability, and also the needs of society itself. This means that public schools offer more than academic subjects. It surprises many people when they come here to find high schools offering such courses as typing, sewing, radio repair, computer programming or driver training, along with traditional academic subjects such as mathematics, history, and languages. Students choose their curricula depending on their interests, future goals, and level of ability. The underlying goal of American education is to develop every child to the utmost of his or her own possibilities, and to give each one a sense of civic (公民的) and community consciousness.
Schools have traditionally played an important role in creating national unity and "Americanizing" the millions of immigrants who have poured into this country from many different backgrounds and origins. Schools still play a large role in the community, especially in the small towns.
The approach to teaching may seem unfamiliar to many, not only because it is informal, but also because there is not much emphasis on learning facts. Instead, Americans try to teach their children to think for themselves and to develop their own intellectual and creative abilities. Students spend much time, learning how to use resource materials, libraries, statistics and computers. Americans believe that if children are taught to reason well and to research well, they will be able to find whatever facts they need throughout the rest of their lives. Knowing how to solve problems is considered more important than the accumulation of facts.
This is America"s answer to the searching question that thoughtful parents all over the world are asking themselves in the fast-moving time: "How can one prepare today"s child for a tomorrow that one can neither predict nor understand?"

单选题People talked about a promising idea: using the electrical wiring already in the house to move data from room to room. One early application, the X10 system for controlling lights and appliances, didn"t always work welL The technology was certainly not ready to be used to bring web pages to computers anywhere in the house.
Along came the wireless network. For $ 50, you could get the Ethernet sprayed across the house and never be confined by a cord to the wall. It was slow in those early days, very unreliable, and open to interruption if you couldn"t bother with setting up the encoded passwords.
But it caught on. According to estimates made by Parks Associates, a market research firm based in Dallas, about 12.5 million homes now have wireless networks; another 10 million homes, mostly newer ones, have Ethernet.
Cheap and prevalent is a hard combination to beat. However, technology companies continued to work on the idea. A version for power lines called Home Plug came out in 2002, and while it hardly affected sales of wireless network equipment, it sold enough that major companies like Intel, Cisco Sony, Sharp and Comcast created the Home Plug Alliance to push for next-generation products, with the first to come out later this year.
Some companies are not waiting. Panasonic, Netgear, Maranta are already offering products that will move data through home electrical lines faster than routers using the current Wi-Fi standard for wireless networking.
Panasonic started selling its HD-PLC Ethernet adapters for power lines last month. One adapter is attached to a router with a short Ethernet cable and plugged into a nearby wall socket. The second device is plugged into a socket elsewhere in the house. When a computer is linked to it with an Ethernet cable, data is transmitted through the home"s electrical wiring at speeds of up to 190 megabits a second.
Netgear will be selling a similar system next month for about $ 300. It moves data at a slightly faster rate. Marantz says its ZR6001SP receiver will send music to special speakers in another room over power lines. The system includes both devices. The music listener controls the receiver and the CD players connected to it form a control pad on the speakers.
These products seem hopeless candidates. Who would like to pay two or three times expensive than wireless network? The answer lies in simplicity. "It"s why most people need us," Robert said, noting the complexity of installing wireless network is evident by the fact that return rates on wireless networking devices drop to nearly zero. The three products" makers said that people who cannot get whole-house coverage with a wireless system or those plagued by dead zones might find it appealing.
