Game time.
Watch the video and learn how we change a verb into the past tense.
We add -ed to the verb.
Do the 'ed' endings in these verbs have the same pronunciation
huntedplayed
helped
/ d/
/d/
/t/
/t/ talked picked helped stopped finished
/d/ moved climbed filled tried enjoyed
/ d/ wanted visited tasted needed ended
Can you summarize the rules
一般情况下,动词过去式屈折词尾-ed的发音遵循“清-清,浊-浊”规律,即-ed在清辅音后发清辅音/t/,在浊辅音或元音后发浊辅音/d/。如果以/t/或/d/结尾,则-ed发音需要加一个元音,即发/ d/,让发音更省力、流畅。
Listen and repeat. Notice the pronunciation of -(e)d.
2
What is a contraction
Let's learn how to pronounce some negative contractions.
A contraction is a combination of two separate words, with some letters omitted and replaced with an apostrophe. Contractions happen in informal speech and writing. They help make sentences more fluid and quicker to say.
缩写形式是两个独立单词的组合,其中一些字母被省略并用撇号(')代替。缩写形式常用于非正式的口语和书面语中,它们使句子更流畅,读起来更快。
写出下面单词的否定式,总结其发音。
