定語從句核心規則
1從句完整使用
關係副詞 when where why
2從句不完整 用
關係代詞 :
人 who whom that
物 which that
xx的 whose
This is the boy without whose help I can‘t have passed the difficult exam。
這就是那個男孩,沒有他的幫助,我不可能透過這次困難的考試。
解析:從句主語前有名詞help,所以用whose
Because the moon’s body blocks direct radio communicationcommunication with a probe。 China first had to put a satellite in orbit above the moon in a spot where it could send signals to the spacecraft and to earth。
因為月球的身體阻礙了與探測器的直接無線電通訊。中國首先必須把一顆衛星放在月球上方的軌道上,在那裡它可以向宇宙飛船和地球傳送訊號。
解析:從句完整用關係副詞(when where why),先行詞spot為地點,所以用where
非限制定語從句只能使用which(有逗號分割)
Vegetables that people leave uneaten are often the most nutritious。
人們不吃的蔬菜往往是最有營養的。
Broccoli, which people often leave uneaten, is very nutritious。
人們經常不吃的西蘭花營養豐富。
