VOA一分钟英语：频率副词在句中的位置

你知道用来表示频率的英语副词 “always”、“never” 等在句子中的位置吗？
 
Welcome to BBC Learning English! I'm Sam and today we're going to look at adverbs of frequency.
You know these… always, sometimes, never…
But, where do they go in a sentence? Look at alwaysin this sentence – does it come before or after the verb?
Helenalwaysstarts work at 7:00.
The verb is ‘starts’ and alwayscomes before. Rule number one.
Next sentence: Helen isn’talwayshappy about this.
The verb is 'is' andalwayswas after. Rule number two.
Last sentence: Helen hasalwayshated early starts.
Trick question! There was an auxiliary verb 'has' and a main verb 'hated' and alwayswent after the auxiliary verb. Rule number three.
 
用法总结
三条规律记住部分频率副词在句子中的位置：
1 频率副词在行为动词前。
Helen alwaysstarts work at 7:00.
 
2 频率副词在系动词 “be” 后。
Helen isn’t alwayshappy about this.
 
3 主动词前面有助动词的情况下，频率副词放在助动词后。
Helen has alwayshated early starts.
