(四)其他应注意的确问题: (1) 同位语从句只能用"that"连接 常见的同位语先行词有:fact(事实), possibility(可能), idea(想法), belief(相信), doubt(疑问), news(消息), order(命令), promise(承诺), evidence1(证据), suggestion(建议)等,例如: Is there any possibility that all the villagers can send their children to school?(有没有这种可能,所有村民都能送他们的孩子上学?) There can be no doubt that he is a qualified2 doctor.(毫无疑问,他是个合格的医生。) (2) "as" 也可以做关系代词用于连接定语从句,特别是在"such…as…", "the same as…" 以及"正如…"的结构中,例如: I have never seen a thing as he described. (我从未见过他所描述的那种事。) As was expected, the performance was a great success. (正如所料,演出获得了巨大成功。) 把该句理解为:The performance was a great success, which was expected,就比较容易理解as的这种用法。 将定语从句的连接用三句话归纳一下: ↗ 人用who / whom (1)先行词在从句中当主、宾、表语 →定语用whose ↘ 物用that (= which)/ 非限制用which ↗地点状语用:where (2)先行词在从句中当 →原因状语(reason)用:why ↘ 时间状语用:when (3)介词 + which / whom结构:瞻前顾后 点击收听单词发音
