British phonetic symbols
The English phonetic symbols are constantly improving. Modern linguists believe that the/tr/,/dr/ts/,/dz//dz/ It is not an independent phonetic level, so the phonetic table of the traditional DJ phonetic table has been deleted in the phonetic sign on the BBC English website. As a result of the consonant of American phonetic symbols, the British phonetic symbols are 24 consonants.

wholesale fashion jewelry made in korea Pay content for time limit to check for freenAnswer 1 syllable syllable is the basic unit of pronunciation. The pronunciation of any word is decomposed as a syllables. The vowels in English are particularly loud. A vowel can form a syllable. A binding of a vowel and one or more consonant phonetic can also form a syllable. Generally speaking, vowels can constitute syllables. The consonants are not loud and cannot constitute syllables. However, there are 4 consonants in English consonants [m], [n], [ng], [L] are loud sound. They are combined with consonant phonetos, and they can also constitute syllables. The syllables of their composition often appear at the end of the word, generally non -repeat syllables. English words have a syllable, two syllables, multiple syllables, one syllable called single syllable, two syllables are called dual syllables, and three syllables are called multi -syllables. 2 The method of dividing syllables is the main body of the syllable, and the consonant is the dividing line of the syllable. No matter how many voices between the two consonants are, they are usually a syllable. 1. When there is a consonant letter between the dual -vowel letters, the consonant letter is returned to a syllabus. 2. When there are two consonant letters, a consonant letter returns to the first syllable, a syllabus of the post, 3. cannot be split to be split. The letter combination is divided into syllables by combination of letters. 3 How to identify open syllables and closed syllables 1. Open syllable 1) The syllables ending with pronunciation phonetic letters. Example: BE, HE. Formula: Cuxeno -voice a vowel 2) The syllables ended by the consonant (except) the e -pronunciation E. Example: Make, like. Formula: A vowel one or more consonant e2 without pronunciation. The closed syllables end with one or more consonant letters (except R) and there is only one phonetic letter syllable in the middle, called closed syllables. Example: Map, Desk, IS. The vowel letters are read as short vowels in the re -read -readable closed syllables.
how to create a wholesale line sheet for jewelry There are two major magic weapons for learning English, one is called "KK phonetic symbol", and the other is called "pronunciation book". The KK phonetic symbol is a phrase of American English. It is a form of phonetic writing. There are 50 in total. The pronunciation book is the pronunciation rules of American English, that is, what the letters are under what circumstances.
American English and Chinese are different. Chinese is a block word. In order to write the words neatly and beautiful, people write the compartment of the materials written in the square and write in the square. After the emergence of live printing in the Song Dynasty, people created characters in the rules block template, especially in modern times. Any sound, that is, the word and pronunciation are completely unjust. For example, the word "嬲", does not read "male", does not read "female", but the sound of "birds", that is, Niao three voices Essence American English is Pinyin text, which is composed of letters, and its pronunciation is represented by letters. There are 26 American English letters, of which A, E, I, O, and U are vowel letters, and the remaining 21 are consonant letters. Among them, the Y letters are sometimes used as vowel letters. Each letter can have one or more pronunciation. Therefore, there are 50 phonetic spaces in American English. The writing form of the phonetic position is the phonetic letter, that is, the phonetic symbol, a phonetic letter, the phonetic symbol, indicating a phonetic position.

The pronunciation book is the pronunciation rules of American English. The biggest feature of American English is that they are consistent with spelling and pronunciation. Such as Brother, there is a letters R when spelling, so it must read the pronunciation of this letter R, like Fast, which is a re -read -closed word, so the letter A must read its short sound. Another example is CLERK, and American English reads the pronunciation rules of ER in R syllables. Pay attention to rolling tongue. Another example is American English writing the theater as theater instead of Theater because its original spelling is inconsistent with pronunciation.
. The syllables of English can be divided into three types: open syllable, closed syllable and R syllables. The syllable can be divided into absolute open syllables and relative open syllables. Absolutely open -vowel letters are the last letters in the syllable. If this syllable is read the syllable, this vowel letter will grow vowels.

learned to pronounce, and then started to learn grammar. English belongs to the Germanic Western language branch of the Indo -European language. , Arabic, and vocabulary introduced in other languages. English belongs to the flexion, but its folding changes are relatively small. Except for nouns, pronouns, verbs, adjectives, and adverbial changes in the form, numerals, crown words, prepositions, connectors, and sighs are unchanged. There are only three sentence structures: simple sentences, parallel sentences, and composite sentences. The word order is relatively fixed.
The key grammar includes:
nouns and crown words.
representatives.
.
The verbs (the tense of the verb, passive voice, aid verb, irregularity, noun, segmentation, virtual vitality).
adjectives, adhesions, comparisons.
MOE, connective and sigh.
five of the sentence patterns.
The negative and doubt.
types of sentences (the usage of connectors and relations).
The special sentences (emphasizing sentences, omitted sentences, inverted sentences).
This English is best to listen to Obama's speech, instead of using some Chinese teachers' methodology, because some Chinese teachers are pronounced inaccurate, and the grammar is wrong. Follow them to learn more and more wrong. As long as you learn with your heart, you will be able to learn the language of English well, and I hope I can help you.
