VOA一分鐘英語(yǔ)：頻率副詞在句中的位置

你知道用來(lái)表示頻率的英語(yǔ)副詞 “always”、“never” 等在句子中的位置嗎？
 
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.
 
用法總結(jié)
三條規(guī)律記住部分頻率副詞在句子中的位置：
1 頻率副詞在行為動(dòng)詞前。
Helen alwaysstarts work at 7:00.
 
2 頻率副詞在系動(dòng)詞 “be” 后。
Helen isn’t alwayshappy about this.
 
3 主動(dòng)詞前面有助動(dòng)詞的情況下，頻率副詞放在助動(dòng)詞后。
Helen has alwayshated early starts.
