调整句子顺序来分析:This research center is ---you visited last year ? 显然,原句缺表语,用the one 来替代This research center ,填上the one 后,再来看the one 在其后的定语从句中作什么成份。显然,the one 是you visited 的宾语,当先行词为物,切在定语从句中作宾语时,关系代词可以省略,故,the one (that ) 正确 。 对比:Is this the research center ---you visited last year ?这个句子调整语序后为 this is the research center ---you visited last year ? 原句不缺表语,只需考虑定语从句关系代词的选择,用 which ,that或者
