The intonation.（语调）
Express the different feelings of the speaker.
We often use the falling tone when we read a statement, a special question, an exclamatory or imperative sentence(祈使句、感叹句). We often use rising tone when we ask a Yes/No question. We often use rising-falling tone to read an alternative question and a coordinate clause（选择疑问句、并列句）. There are two parts in a tag question（反义疑问句）. The first part is often in a falling tone and for second part, there are two cases. If we are not sure about the question, we often use a rising tone. If we are sure about that, we offen use a falling tone.
We choose different intonations to express different feelings and moods.
The word stress(单词重音)
Read words more exactly
When we say a word with more than one syllable, some of the syllables need to be stressed.
When we read two-syllable words, normally we stress the first syllable for nouns, and stress the second syllable for verbs. As for the multi-syllable words, we stress the third from the bottom.
The sentence stress（句子重读）
Draw attention to certain information.
We usually stress the lexical words such as nouns, verbs, adjectives, adverbs and numbers. We don’t stress the function words such as a, the, is, of and so on. Besides, you can stress some information you want to emphasis.
We should change it according to the situation and feelings of the speaker.
The liaison/ˈlēəˌzän,lēˈāˌzän//Word linking.(连读)
Speak English more fluently and naturally.
In one sense group, we can read the two words together if the former word ends with a consonant/ˈkänsənənt/, a vowel or “r” sound, and the following word begins with a vowel. If the two words finish and start with the same consonant, we only read one of the consonants.
The two words must be in one sense group.
incomplete plosion/‘pləʊʒ(ə)n/（不完全爆破）
Speak English more fluently and naturally.
There are six plosive sounds /t/ /d/ /p/ /b/ /k/ /g/ in English.When two consonants of them are next to each other, we read the former sound silently.
The two words must be in one sense group.
Weak form(弱读)
speak English more fluently and naturally.
Some words often appear in a weak form such as function words, articles, auxiliary verbs and modal verbs.
there are mainly three ways to change function words to weak forms. They are shortening, elision[ i’liʒən ] and vowel changed to schwa [ʃwɑ:] sound.
Assimilation(同化)
We use it to speak English more fluently and naturally.
As we can see, Two different sounds affect each other and become more alike.
/s+ j/ -> /F/this year,/d+j/ -> /d3/ would you
Sense group(意群)
We use it to make our expression more easily to understand.
As we can see, a sentence may consists of several groups according to meaning or structure. Each group is called a sense group. It can be a word, a phrase, a clause. After a sense group, there should be a short pause.
We should remind that we should change it according to the situation and feelings of the speaker.
The pause(停顿)
We use to speak English more fluently and naturally.
As we can see, in a long sentence, we should pause several times according to the sense group. Normally, we pause based on meaning and grammatical structure.
We should remind that there should be no pause in a sense group. Where to pause also depends on the situation and the feelings of the speaker.
