1）The school board ruling mandating that physicaly handicapped students be placed in regular classroom setting whenever possible also assured all children who have a reading problem of special aid D) be placed in regular classroom setting whenever possible also assured children with reading problems 答案是D，我选A，当时我考虑“ a reading problem”，是个整体概括，而且who表达关系更清晰。
2）where once the union had acquiesced to the prjudices of its English-speaking members by supporting the imposition of an alien tax on immigranted workers, after 1897 the united mine workers make a determined effort to enlist Italian and Slavs in its ranks. C)while once the union had acquiesced to the prjudices of its English-speaking members in support of 答案是A，我先C，“ in support of ”为什么不对？作者: tocean0222 时间: 2003-7-5 12:49
1、这里的all children不是整体概念，handicap是多样的，因此problem也是不同的，所以该用复数，并且用with比who从句更为简洁；
2、c的while once就错了，只有where once的用法； 另外in support of 没有直接用support来的简洁！
