Welcome to Daily tips on Learning English. Today's tip is on distinguishing “can” and “cannot” in spoken American English.今天我們的主題是can和cannot發(fā)音的區(qū)別

“Cannot” is usually contracted to “can't”. 通常我們?cè)诎l(fā)cannot這個(gè)詞的時(shí)候我們不是說(shuō)cannot而是說(shuō)can't。

So many learners of English assume that in order to distinguish between “can” and “can't”, one must listen for the final “t” sound /t/. And when speaking, one must pronounce final ‘t’ sound /t/ clearly. However, this is not in fact how native speakers distinguish “can” and “can't”. 通常我們以為我們?cè)诼?tīng)或我們?cè)谡f(shuō)英文的時(shí)候我們要把那個(gè)/t

/發(fā)出來(lái)，或者是說(shuō)我們要聽(tīng)到那個(gè)/t/我們才知道別人在說(shuō)can't，這個(gè)是不可以的，其實(shí)美國(guó)人并不是以此來(lái)區(qū)別的，People do not say ‘I `can drive a car, but I `can’t drive a motorcycle.’ People say ‘I can `drive a car', but I `can't drive a motorcycle.’ The difference between “can” and “can't” is in stress. “Can” is not stressed, the verb after it is. “Can't” is stressed. The verb after it is not. 請(qǐng)注意，我不知道你剛剛有沒(méi)有分別出來(lái)，當(dāng)我們?cè)谡f(shuō)我們可以的時(shí)候，我們要把那個(gè)can發(fā)得比較輕一點(diǎn)，要把重音放在can后面的動(dòng)詞上面，當(dāng)我們?cè)谡f(shuō)不可以can't的時(shí)候，我們不是要把那個(gè)/t/發(fā)得很清楚，而是我們要把重音放在can上面

Also since ‘can’ is not stressed, the vowel is reduced to /a/, so “can” is actually pronounced “can”. 你們不曉得有么有聽(tīng)出來(lái)，我們老師剛發(fā)的音，當(dāng)你沒(méi)有把重音放在can的時(shí)候，可以的時(shí)候我們要把那個(gè)母音發(fā)成/a/，

Listen to another example. 讓我們?cè)賮?lái)聽(tīng)另外一個(gè)例子，請(qǐng)注意聽(tīng)，“I `can't go on Saturday, but I can `go on Sunday.” Did you hear the 't' sound? Did you notice the difference words being stressed? Listening again. “I `can't go on Saturday, but I can `go on Sunday.” If you want to understand whether someone is saying he can or can't do something, you have to be listening for a stressed “can't” or a verb stressed after “can”. 請(qǐng)注意我們老師剛剛給你們的例子，也就是在說(shuō)明can drive當(dāng)重音放在drive上面的時(shí)候那表示可以，當(dāng)我們把重音放在can't這個(gè)can上面的時(shí)候表示他不可以。What does this mean? “I can `speak Japanese, but I `can't speak Taiwanese.” That's right, I can speak Japanese, but I cannot speak Taiwanese. When you are speaking it is very important that you follow this rule too. When learners of English say I `can help you, native speakers often unsure what is meant because of improper stress. 請(qǐng)注意，你不能說(shuō)I `can help you，就是你把重音放在can上面的時(shí)候人家會(huì)以為你不能幫他，其實(shí)你要說(shuō)I can `help you，就是把重音放在help上面，而不是把重音放在can上面。

So remember, you can stress “can't”, but you `can't stress “can”.
