使用场景

Part 2 Pronunciation and intonation
发音讲解
So,in the sentence,pay attention to the pro-nunciation of these parts.
在这一句中，注意以下部分的发音：
1.When you say "have to",don't use too much strength on the/v/sound in "have",and weaken "to" to make it/tə/.
1.说 “have to” 时，不要重读“have” 中/v/这个音，“to” 弱读为/tə/。
2.In "a lot of" "of" is reduced to/ə/,with-out the/v/sound.
2.“a lot of” 中，“of” 弱读为/ə/，不要发/v/这个音。
3.Say "you're"/jʊə(r)/differently than"your"/jɔːr/.But when you say them really fast,they both sound more like/jər/.That's why even many native speakers confuse them in writing.
3.“you're”/jʊə（r）/的发音与“your”/jɔːr/不同。但当你快读时，它们听起来都像/jər/，这就是为什么很多英语母语者书写的时候也会混淆。
现在，我们重点看看语气和语调。
Now,let's focus on tone and intonation.
1.重读 “have” “lot” “fiber” 和“constipated”。
1.Stress "have" "lot" "fiber",and "consti-pated".
2.发 “have” 这个音时要比平时急促，音高应该是整句中最高的。
2.Make the word "have" sound more urgent than usual,the pitch is the highest in the sen-tence.
现在，你知道怎么像英语母语人士一样说这句话了。
So,now you know how to say this sentence like a native speaker.
