在这节课上，我们将要学习/have/ 和 /has/的重读和轻读。

We can pronounce have and has in different ways. There is a weak form and a strong form of each.

Weak forms: hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/schwa.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />v and hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/schwa.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />s
Strong forms: hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/a.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />v and hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/a.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />s

We often use the strong form in short answers and in the negative. For example:

Yes, I have. /hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/a.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />v/
They haven't seen the new policy yet. /hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/a.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />v'nt/
We haven't done the test. /hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/a.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />v'nt/

We often use the weak form in questions.

Have you ever been to Canada? /hhttp://cnak.englishtown.com/schoolcontent4/_imgs/phonemes/schwa.gif和 /has/的重读和轻读" TITLE="/have/ 和 /has/的重读和轻读" />v/
