非限定性定语从句 补充说明主句内容

as VS which  的区别

as 可指代整个主句,强调“正如…所说/所见/常见”,带有 “众所周知” 的语气(从句可出现在句首、句中或句尾)
which 也可指代整个主句,但语气为 “补充说明”,无“正如”之意(从句只能位于主句之后)

省略结构:as + be + done “as reported”结构 As (is) reported, a foreign delegation will visit. 如报道所说,一个外国代表团将到访。
省略结构:which + be “which was at large”结构 A puma (which was) at large was caught. 一只在逃的美洲狮被抓住了。

nor 部分倒装

differentiate A from B 区分 Can you differentiate right from wrong? 你能分辨是非吗?
discriminate between A and B 辨别 Children learn to discriminate between acceptable and unacceptable behavior. 孩子们学会分辨可接受和不可接受的行为。

省略结构 并列句省略(重复的内容不引起歧义的情况下)

  • Paul likes poetry, and Peter (likes) fiction. Paul喜欢诗歌,Peter喜欢小说。
  • Paul likes poetry, and I know that Peter likes fiction. 不能省略:因为位置宾语从句内部
  • He enjoys swimming, and she (enjoys) diving. 他喜欢游泳,她喜欢跳水。
