另一方面，从属连词（或者从属词）联接句法地位不对等的成分。 
 

I left early because I had an interview the next day  我早早离开了，因为第二天我有个面试。
We visited Madame Tussaud's while we were in London  我们在伦敦的时候参观了杜莎夫人蜡像馆
I'll be home at nine if I can get a taxi  如果能叫到出租车的话我会在九点到家

并列句和从属句在语法上是相当不同的概念。例如，并连词必须出现在并列项之间。
 

[Paul plays football] and [David plays chess]

 ~*And [David plays chess] [Paul plays football] 

[David plays chess] and [Paul plays football]

I left early because I had an interview the next day我早早离开了，因为第二天有个面试

~Because I had an interview the next day, I left early 因为第二天有个面试，我早早离开了

I left early because I had an interview the next day我早早离开了，因为我第二天有个面试

~I had an interview the next day because I left early我第二天有个面试，因为我早早离开了 

要么造出一个有问题的句子来：
 

I'll be home at nine if I can get a taxi如果能叫到出租车的话我会在九点到家

~?I can get a taxi if I'll be home at nine  如果我会在九点到家的话，我能叫到出租车
