In this American English pronunciation video, we're going to go over how to pronounce the word THAT in a sentence.
在这节美式英语发音视频中，我们将要学习句子中的“that”如何发音。
As you probably know, in American English, there are lots of words called function words that will be unstressed in a sentence. And some of these will reduce.
你们应该知道，在美式英语中，有许多词被称为功能词，这些词在句子中不重读，有一些则要弱读。
THAT is one of those words. In a sentence, the vowel will often reduce to the schwa sound.
that就是这样的词。在一个句子中，元音经常会弱化为弱读音。
The final T will be a stop T if the next word begins with a consonant, or it will be a flap T if the next word begins with a vowel or diphthong.
如果下一个单词的首字母为辅音，则结尾的T为停顿T；如果下一个单词的首字母为元音或双元音，则结尾的T为闪音T。

The voiced, TH, where the tongue tip comes just through the teeth.
th发音时，舌尖要伸出，位于上下齿之间。
Then for the schwa sound, the tongue tip pulls back and comes down, rests just behind the bottom front teeth, and the tongue is very relaxed.
而对于弱读音，舌尖收回放下，置于下前牙后，舌头放松。
For the T, flap or stop, the tongue tip will go to the roof of the mouth, and cut off the air flow for the stop T, or bounce back down, letting the air through for the flap T.
无论是闪音T还是停顿T，舌尖都要抵住上颚，停顿T时要切断空气流动，闪音T则要反弹回来，让空气通过。
Let's look at some sample sentence fragments.
让我们来看一些句子片段示例。
“that my.” (loop two times) The next word here, my, begins with a consonant. So the T at the end of the word 'that' is a stop: that my.
“that my ”（循环两次）这里的下一个单词“my”，首字母是辅音，所以“that”结尾的字母T是一个停顿T，“that my”。
“that I.” (loop two times) The next word here, I, has the AI diphthong. So, the T at the end of the word 'that' is a flap T. “that I.” (loop two times).
“that I”（循环两次）这里的下一个单词“I”是双元音(ai]，所以“that”结尾的T是闪音T，“that I”（循环两次）。
Now, let's look at some full sentences.
现在，我们来看一些完整的句子。
The movie that I saw was boring. “that I.” (loop two times) Again, the AI diphthong, so the T is a flap. That I.The movie that I saw was boring.
The movie that I saw was boring.“that I”（循环两次）因为双元音(ai)，所以T是闪音。That I.The movie that I saw was boring.
We thought that we could be there. “that we.” (loop two times) So, the word 'we', beginning with the W consonant, the T is a stop T.
We thought that we could be there.“that we”（循环两次）单词we首字母是辅音W，所以T是停顿T。
“that we.” (loop two times) We thought that we could be there.
“that we”（循环两次）We thought that we could be there.
I know that you're disappointed. “that you're.” (loop two times) So, the next word here begins with the Y consonant, so the T is a stop T.
I know that you're disappointed. “that you're” （循环两次）这里的下一个单词以辅音Y开头，所以T是停顿T。
“that” (loop two times), “that you're.” (loop two times). I know that you're disappointed.
“that”（循环两次）“that you're”（循环两次） I know that you're disappointed.
I read that her team won. “that her.” (loop two times) Here, with the word 'her', I'm dropping the H.
I read that her team won. “that her”（循环两次）在这里，单词“her”省略了“H”，
So, the sound after the T, is the schwa sound, a vowel. Therefore, it's a flap T. “that her.” (loop two times) I heard that her team won.
所以T后面的发音是弱读音。因此，这里是闪音T。“that her”（循环两次）I heard that her team won.
Will the word 'that' always be pronounced this way in a sentence? No. Sometimes it will have the AA vowel.
句子中的“that”一直都是这样发音吗？不。有时它会发元音AA的音。
For example, if you want to stress the word: It was easy. It wasn't that easy.
例如，如果你想要强调单词：It was easy. It wasn't that easy.
Thaa, aa. There, I'm keeping the AA vowel. Also, in this sentence, the word 'that' is an adverb. And adverbs are generally content words, not going to reduce in a sentence.
Thaa，aa. 这里我保留了元音AA。这句话中，单词“that”是一个副词，副词通常是实义词，在一个句子中不会弱读。
But you will often hear the word 'that' reduced. Doing it yourself will help to smooth out your speech,
但是你会经常听到单词“that”弱读。自己这样练习会使你的演讲更加流利，
and will also provide some nice rhythmic contrast to the longer, stressed syllables in a sentence.
也会提供一些很好的节奏，与句子中较长的重读音节形成对比。
