More than 650 sets of twins, triplets(三胞胎) and multiply births from around the world gathered at a Beijing park on Tuesday for the fourth Beijing Twins Culture Festival, a highlight of the city’s National Day celebrations.
When those look-alikes walked on the red carpet 26 (prepare) by the even sponsor, at the Honglingjin Park in the eastern part of Beijing, thousands of viewers took photos accompanied(伴随) by cheers.
“I feel just like a star,” said a 5-year-old girl Wang Yufei, 27 came to Beijing with her twin sister Wang Yutong.
Ten pairs of twins were picked out 28 (attend) a simulated(模拟的) torch relay. And it was ended 29 the chanting of slogans of next year’s Olympics by all twins.
Other activities included performances of singing, dancing, cross talks and martial arts.
The first Beijing Twins Culture Festival was held on Oct.2,2004, 30 attracted more than 500 pairs of twins, and 31 event has become an annual one, according to the organizers.
Chinese, who prefer “double” 32 “single” by tradition and always wish newly-weds (新婚夫妇) “double happiness”, look on twins and multiply births 33 signs of good luck. A boy-and-girl 34 (call) a “dragon and phoenix” pair-a reference to two 35 (tradition) symbols of prosperity.
American public education has changed in recent years. One change is that increasing numbers of American parents and teachers are starting independent public school 11 charter schools (特许学校).
In 1991, there were no charter schools in the United States. Today, more than2,300 charter schools 12 in 34 states and the District of Columbia. 575,000 students 13 these schools. The students are from 5 years of age through 18 or older.
A charter school is 14 by groups of parents, teachers and community (社区) members, It is similar in some ways 15 a traditional public school. It receives tax money to operate just as other public schools do. The 16 it receives depends on the number of students. The charter school must prove to local or state governments that its students are learning. These governments 17 the school with the agreement, or charter that permits it to operate.
Unlike a traditional public school, 18 the charter school does not have to obey most laws which govern public schools. Local, state or federal governments cannot tell it what to 19 .
Each school can choose its own goals and decide the ways it wants to 20 those goals. Class sizes usually are smaller than those in many traditional public schools. Many students and parents say 21 in charter schools may be more creative.
However, state education agencies, local education-governing committees and unions are often 22 charter schools. They say these schools may receive money badly 23 by traditional public schools. Experts say some charter schools are doing well while others are struggling.
Congress provided 200million dollars for 24 charter schools in the 2002 federal budget (预算). But often the schools say they lack enough money for their 25 .Many also lack needed space.
