六年级英语辩不同发音的词
①I play(ed) football with my classmates last Saturday afternoon
②Tom'family liv(ed) in New Yort
③Mary is good at dancing.She danc(ed)wonderfully last night.
④I learn(ed) to swim when I was only nine years old
这四句话中的ed发音和其他不同的是（ ）并写出为什么发音不同
答
这四句话中的ed发音和其他不同的是（3、danced）.
ed在元音和浊辅音后读/ d /,在清辅音后发/ t /.
played、lived、learned这三个的ed都发/ d /,danced结尾的c字母发清辅音/ s /,ed发/ t /.
