基本操作题下面的程序是10000以内的"相亲数"。所谓相亲数是指这样的一对数:甲数的约数之和等于乙数,而乙数的约数等于甲数,(例如220和284是一对相亲数)请在程序的每条横线处填写一条语句,使程序的功能完整。注意:请勿改动main()主方法和其他已有的语句内容,仅在横线处填入适当的语句。public class QinShu{ public static void main(String args[ ]){ for(int n=1;n<9999;n++){ int s=divsum(n); if( ) System.out.println(n+","+s); } }public static int divsum(int n){//该方法的功能是求一个数的所有约数 int s=0; for(int i=1; i++) if( )s+=i; return s;} }
Are teens and young adults more narcissistic (自恋的) today than in the past That’s the view of a California researcher who studies (1) people. In her new book, The Narcissism (2) : Living in the Age of Entitlement, psychologist Jean Twenge of San Diego State University and (3) W. Keith Campbell of the University of Georgia say research shows (4) young people today have "narcissistic traits" than in (5) generations. Such traits, Twenge says, include a very. (6) and inflated sense of self, which is (7) by a preoccupation with MySpace, Facebook and YouTube. "We’ve been on this self-admiration cultural (8) for a long time," Twenge says. (9) Twenge’s take on today’s young people isn’t universal. Studies by other researchers, including Canadian (10) Dr. Kali of the University of Western Ontario, have used the same data but found (11) results. "They put a different (12) on it," Kali says. Twenge’s studies have found more narcissistic traits and a (13) rate of increase among college students today, but Kali found that students’ narcissism was (14) greater in 2006 than in 1976. Twenge’s most recent paper studied the same data as Kali--more than 20 000 college students from 2002 to 2007. (15) researchers used the Narcissistic Personality Inventory to measure narcissistic (16) and findings by both have been (17) in peerreviewed journals. Twenge’s book (18) just a month after The Mirror Effect : How Celebrity Narcissism Is Seducing America, a book co-written by behavioral (19) Drew Pinsky, (20) suggested that a celebrity-obsessed culture is causing more narcissism.

Electronics are being recycled in record numbers as more states require it and more companies collect and even pay for discarded items, but the gains come with controversy. Some environmentalists complain that recycling is not keeping pace with electronics sales. Some say e-waste is being dumped in developing countries, where toxic materials such as lead and mercury can leach from landfills into groundwater. "It is a success story, but we’d like to see it get more successful" to keep up with the electronics boom, says Janette Petersen of the Environmental Protection Agency (EPA). The amount of recycled items more than doubled from 1999 to 2007, the most recent year for which the EPA has figures. But as a percentage of all electronics, it increased less, from 15% to 18%. "The demand for electronics recycling has been growing," partly because of the switch last year to digital TV, says Jennifer Berry of Earth911. corn, a private group that keeps a database of recyclers. Last year, she says 31% of inquiries involved electronics, primarily TVs, batteries and computers. Public and private efforts are expanding. Vermont became the 21st state last month to enact a law that requires e-waste recycling. Twenty-six companies--including Dell, Hewlett Packard, AT&T and Verizon--have partnered with the EPA on the Plug-In to eCycling program to promote electronics recycling since its launch in 2003. Companies such as Gazelle. corn pay for used gadgets such as iPods, which they resell or recycle. Best Buy and other stores are collecting more e-waste. Target announced last month that it put bins in every store to accept cellphones, MP3 players and ink cartridges. Jim Puckett of Basel Action Network, a Seattle-based non-profit organization that aims to stop toxic exports, worries that some American companies dump e-waste in Africa to save money. "People are trying to look green, but they’re not telling you where it (waste) is going," he says. "You can’t turn over your TV to just any recycler. " He says it’s better to store an old TV than give it to a recycler that may export it to poor countries. The Basel Action Network announced its e-Stewards program last month to ensure safe handling of electronics by using only recyclers certified by accredited organizations. It now lists 45 recyclers in 80 locations. Samsung and other companies have signed on. Environmental groups, including the Sierra Club, back it. According to Jim Puckett, you cannot give your electronics to recyclers because ______.
A. recyelers don’t tell you where the electronics will go
B. you may be cheated by recyclers for not knowing the electronics’ value
C. recyclers may export the electronics to poor countries
D. you can store your electronics for a better price
