阅读理解。 On the outside Betsy Lueth's school looks like any other in Minneapolis. Yet inside, it is Yinghua Academy, a public school where elementary (小学) students study subjects ranging from math to American history in Chinese. Yinghua, the first such immersion (沉浸式) program in the Midwest is on the leading edge of a movement that in recent years has seen Chinese language programs spread rapidly throughout the U.S. The idea behind Yinghua is to introduce kids to the language and culture as early as possible-ideally, before age 12. Kindergarteners and first graders are taught in Chinese and a single period of English is introduced in second grade. By sixth grade, kids are learning half in English and half in Chinese, with the expectation of fluency in both. In Yinghua's classrooms, the walls are covered not with ABCs but with pictures and Chinese characters. There are many challenges at Yinghua. Most teachers come from Taiwan or mainland China, and cultural misunderstandings are very common. Lueth's teachers are learning to be tolerant of local customs-as well as a lot more parental input than they are used to. 'In China, teachers are respected. They are not questioned,' says Luyi Lien, Yinghua's Taiwan-born director. 'In America, parents are more expressive of their opinions.' Research has shown that in the long run, immersion programs can provide benefits, including more flexible, creative thinking. Though students from the programs fall behind for a few years in English, by fifth grade they perform as well as or better than their monolingual (单语言) peers on standardized reading and math tests. For multicultural families, the psychological help can also be important. Lueth, a former teacher, co-founded the school as a way to expose her adopted Chinese daughter Lucy to her native culture. Lucy used to be annoyed when cousins asked why her skin color was different from theirs; before she started at Yinghua, she resisted exploring anything related to China Now, Lueth says, Lucy proudly answers her cousins, 'Yeah, I was born in China.' 1.
