The pronunciation between /θ/ 和/S/ 經常把嘴巴那個單詞mouth發成mouse,就變成了老鼠這個單詞了呀。
發 /s/時,兩腮向兩側拉開,臉要smile,舌靠近前牙,但不touch前牙,然后吹氣就行了.發/s/實際上沒有多大問題,問題出在發/θ/這個音,把舌頭伸到至少跟上下唇一樣齊,然后吹氣.其實,不用伸得那么長了,稍微超過上下齒就行了。
但是在初次練習時,建議還是可以適當的把舌頭多伸出來點,才能感覺到這個發音。多次這樣練習這個音之后,舌頭就很容易可以伸出來發這個音。到時發這個音就不在是問題了。
聽讀下面的句子,注意/s/和/θ/
He saw the thief get in through the window. I have been to the North Sea. The six strings are thinner than that one. Edith will sing a song. They got the third place in the exam. Sina thought better of Tom.
