[单项选择]For months the Japanese searched fitfully for the right word to describe what was happening. At the Bank of Japan, the nation’s central bank, officials spoke of "an adjustment phase.’ Prime Minister admitted only to "a difficult situation." The Economic Planning Agency, the government’s record keeper, referred delicately to a "retreat." Then two weeks ago, for the first time since 1997, the agency dropped its boilerplate reference to the "expansion" from its closely watched Monthly Economic Report, and the word game was over. Japan’s economy, the world’s second largest, conceded the experts, was in recession.
That admission confirmed the bad news businessmen had been reading in their spreadsheets for several months. "In 2001 one market after another turned bad," says Yoshihiko Wakamoto, senior vice president of Toshiba Corp., which now admits that its pretax profits for fiscal 2001, ending March 31, may be down a whopping 42%. In April, when many Japanese companies announce their

[单选题]Passage 1 Hidden Valley looks a lot like the dozens of other camps that dot the woods of central Maine. There′s a lake, some soccer fields and horses. But the campers make the difference. They′re allAmerican parents who have adopted kids from China. They′re at Hidden Valley to find bridgesfrom their children′s old worlds to the new. Diana Becker watches her 3-year-old daughter Mikadance to a Chinese version of "Twinkle, Twinkle Little Star." "Her soul is Chinese," she says, "butreally she′ s growing up American." Hidden Valley and a handful of other "culture camps" serving families with children fromoverseas reflect the huge rise in the number of foreign adoptions, from 7,093 in 1990 to 15,774 lastyear. Most children come from Russia (4,491 last year) and China (4,206) but there are alsothousands of others adopted annually from South America, Asia and Eastern Europe. After cuttingthrough what can be miles of red tape, parents often come home to find a new predicament. "At firstyou think, ′I need a child′," says Sandy Lachter of Washington, D. C., who with her husband, Steve,adopted Amelia,5, from China in 1995. "Then you think, ′What does the child need′" The culture camps give families a place to find answers to those kinds of questions. Most grewout of local support groups; Hidden Valley was started last year by the Boston chapter of Familieswith Children from China, which includes 650 families, while parents address weighty issues likehow to raise kids in a mixed-race family, their children just have fun riding horses, singing Chinesesongs or making scallion pancakes. "My philosophy of camping is that they could be doing anything,as long as they see other Chinese kids with white parents," says the director, Peter Kassen, whoseadopted daughters Hope and Lily are 6 and 4. The camp is a continuation of language and dance classes many of the kids attend during the year. "When we rented out a theater for′Mulan,′ it was packed," says Stephen Chen of Boston, whoseadopted daughter Lindsay is 4. Classes in Chinese language, art and calligraphy are taught byexperts, like Renne Lu of the Greater Boston Chinese Cultural Center. "Our mission is to preserve theheritage," Lu says. Kids who are veteran campers say the experience helps them understand their complexheritage. Sixteen-year-old Alex was born in India and adopted by Kathy and David Brinton ofBoulder, Colo., when he was 7. "I went through a stage where I hated India, hated everything aboutit," he says."You just couldn′t mention India to me." But after six sessions at the East IndiaColorado Heritage Camp, held at Snow Mountain Ranch in Estes Park, Colo., he hopes to travel toIndia after he graduates from high school next year. What is the author′s primary purpose in writing the passage
A.Revealing the procedures for foreign adoptions.
B.Recounting an amazing childhood camping experience.
C.Investigating how Hidden Valley serves foreign adoption families.
D.Demonstrating how culture camps help foreign adoption families.
