语法

本文整理自B站【英语兔】的教学视频,感兴趣的朋友可以自行前往观看。

一、并列连词

  • 谓语动词由靠它最近的主语决定,这是就原则

1.1、并列关系

  • The rabbit is smart and cute.
  • the rabbit teaches English and makes videos.
  • Both the rabbit and the wolf like carrots.
  • the rabbit not only teaches English but also makes videos.
  • the rabbit teaches not only English but also German.
  • the rabbit like neither apples nor pears.表否定
  • neither the rabbit nor the wolf likes apples.表否定

1.2、选择关系

  • what does the rabbit like? apples or carrots?
  • either the rabbit or the wolf is going to the party this evening. 不是……就是……
  • hurry up, or/or else/otherwise you’ll late.表否定

1.3、转折关系

  • the rabbit cooked some carrots, but he didn’t eat any.
  • the rabbit cookes some carrots, yet he didn’t eat any.(yet在这里是并列连词,表转折,而不是副词还没有)
  • I haven’t eaten yet, yet I’m not hungry.
  • the carrots were ready, However, the rabbit was still making videos.
  • the carrots were ready, Nevertheless, the rabbit was still making videos.

1.4、因果关系

  • the rabbit is busy, so he won’t go to the party tonight.
  • the rabbit is busy, therefore, he won’t go to hte party tonight.
  • the rabbit will skip lunch, for he is busy making a video.(for在这里是连词,因为)

二、从属连词

2.1、引导名词性从句

  • that引导名词性从句时(主语,宾语,表语,同位语从句)
    • 只起到连接作用,在句子中没有实际意义
    • 在并于从句中可以省略
  • that the rabbit ate the carrot was obvious.主语从句
  • I saw (that) the rabbit ate the carrot.宾语从句
  • I don’t know if the rabbit ate the carrot.宾语从句
  • the fact is that the rabbit ate the carrot.表语从句
  • the question whether the rabbit will eat the carrot is on all our minds.同位语从句
