Part 2 Pronunciation and intonation
发音讲解
So,in the sentence,pay attention to the pronunciation of these parts.
在这一句中，注意以下部分的发音。
1.First,remember to pause after "helmet".
1.首先，记得 “helmet” 后需要停顿。
2.Link "point of even",and when you can say it fast,leave out the/t/in "point".
2.“point of even” 连读，当你快读时，“point” 中的/t/不发音。
3."wearing a" can be linked in two ways:keep the/ŋ/sound in"wearing",or replace it with/n/,as if you're saying "wearin a".
4.When you say it fast,"not going to" sounds like/ˈnɑːgənə/.
3.“wearing a” 可以以两种方式连读，保留 “wearing” 中的/ŋ/音，或者用/n/代替，好像在读 “wearin a”。
5.Be sure to link "buckle it",and reduce"to" to/tə/.
4.“not going to” 快读时听起来像/ˈnɑːgənə/。
Now,let's focus on tone and intonation.
5.“buckle it” 一定要连读，并且 “to” 弱读成/tə/。
1.Stress these words:"what's" "wearing""buckle".
现在，我们重点看看语气和语调。
1.“what's” “wearing”“buckle” 三个单词重读。
2.Say it in a criticizing tone,because you're not happy when someone behaves recklessly.
