內(nèi)容簡(jiǎn)介

英語(yǔ)中部分動(dòng)詞的過(guò)去式或過(guò)去分詞以后綴 “-ed” 結(jié)尾。在這些動(dòng)詞中，后綴 “-ed” 有三種發(fā)音方式。分別是哪三種？應(yīng)如何判斷？看 “一分鐘英語(yǔ)” 視頻，跟主持人 Phil 學(xué)習(xí)后綴 “-ed” 在動(dòng)詞中的發(fā)音規(guī)則。

文字稿

Did you know these two letters can be pronounced in three different ways? 

They can be /d/, /t/ or /?d/. Here's how to find out which.

First, feel your neck. If a sound makes it vibrate like /d/, then it's voiced. If it doesn't like /t/, then it isn't.

Where 'ed' comes after a vowel or a voiced consonant, then pronounce it as /d/, which is a voiced sound. Played, used.

If you have 'ed' after an unvoiced sound, then it sounds like /t/ – an unvoiced sound. Looked, helped.

If you have 't' or 'd', then 'ed' becomes /?d/ – it's just easier to say. Wanted, needed.

So, if 'ed' comes after a voiced sound, then it's voiced. If it comes after an unvoiced sound, then it's unvoiced, and if it comes after /t/ or /d/, then it's /?d/.
