Most American students go to traditional public schools.There are about 88, 000 public schools, all over the US.Some students attend about 3000 independent public schools called charter schools.

Charter schools are self-governing.Private companies operate some charter schools.They are similar in some ways to traditional public schools.They receive tax money just as other public schools do.Charter schools must prove to local or state governments that their students are learning.These governments provide the schools with the agreement called a charter that permits them to operate.

Charter schools are different because they do not have to obey most laws governing traditional public schools.Local, state, or federal governments cannot tell them what to teach.Each school can choose its own goals and decide the ways it wants to reach them.Class size is usually smaller than in traditional public schools.

The Bush Administration strongly supports charter schools as a way to re-organize public schools that are failing to educate students.But some education agencies and unions oppose charter schools.One teachers' union has just made public the results of the first national study comparing the progress of students in traditional schools and charter schools.

The American Federation of Teachers criticized the government's delay in releasing the results of the study, which is called the National Assessment of Educational Progress.Union education experts say the study shows that charter school students performed worse on math and reading tests than students in regular public schools.

Some experts say the study is not a fair look at charter schools because students in those schools have more problems than students in traditional schools.Other education experts say the study results should make charter school officials demand improved student progress.

“解构”这一概念,最初针对的是理论上的专制,就像拆解一座建筑、一种伪装,德里达希望以此让人从“一切都木已成舟”的观念中解脱出来,以便结构、神经显现出来。但是,当解构主义从一种“反叛的哲学”上升为“统治的哲学”时,其弊端也就显露无遗。正像王朔的小说,如果说对真理和权威的消解显示了其最初的进步意义,那么当其开始“消解一切”、“背叛崇高”之时,就已经走向了反面。
对以上文字理解错误的是:

A.解构是对天经地义的信条的破坏或质疑
B.王朔的小说最初是对权威的消解
C.解构其实是“消解一切”、“背叛崇高”
D.解构上升为“统治的哲学”时,也成了一种理论上的专制
