VOA一分鐘英語：區(qū)分 “th” 在單詞中的兩種發(fā)音

對一些英語初學者來說，“th” 發(fā)音有些難度。“This” 和 “thing” 都以 “th” 開頭，但這兩個詞中的 “th” 發(fā)音一樣嗎？如何區(qū)分 “th” 的濁音 /ð/ 和清音 /θ/？

Let's start with the shape of the mouth.

For both sounds, we put our tongue between our teeth and push air out between them.

The difference is that the first one is voiced, which means we use our vocal cords, and the second one is unvoiced, which means we don't use our vocal cords.

OK, try this:

Voiced – /ð/ vibrations.
Unvoiced – /θ/ no vibrations.

Can you feel the difference?

Now let's practice with some common words you already know: this, thing, though, through, mother, birthday, clothes, fourth, bathe, bath.

And of course, it helps to put them in a sentence:

I never sunbathe, but I love a bath.

But remember to say them out loud, so you're practising the pronunciation.

用法總結

“Th” 的兩種發(fā)音嘴型一樣：將舌頭放在牙齒間，并將氣推出。

發(fā)清音 /θ/ 時，聲帶不震動。以下常見單詞中的 “th” 發(fā)清音 /θ/：

thank
through
