Strange words are rarely used in spoken English. From the perspective of English learning, it is to learn some commonly used words, sentence patterns, slang and so on. Of course, grammar is definitely used in these terms. This idiom is idiomatic English.
The speaker's habit of stringing words together can be called "spoken grammar". We divide the strung sentences into three aspects: sentences describing ourselves, sentences describing others and other things, and social sentences. You should learn these sentences or sentence patterns. In addition, it is necessary to find out the verb tenses that English people often use in spoken English. Finally, pronunciation.
Pronunciation is the most important part of spoken English. No matter how many words we master and how well we master grammar, it is useless for others to understand. Although you don't have to pronounce it perfectly, you should at least be accurate. First of all, we must decide which country's English accent to choose: British? Australian? American? Which English accent you choose depends on your study purpose: which country to study or settle in? What country is the foreign company you work for? If this is not your direct purpose, it doesn't seem to matter which accent you learn. But the important thing is that no matter which one you choose, you'd better learn the image. The most taboo in learning a foreign language is the southern accent and the northern accent. There are three contents in learning spoken English pronunciation: pronunciation, accent and tone. First of all, you must master the pronunciation essentials of monosyllables. Don't speak monosyllables too carefully, because monosyllables can be pronounced accurately. If you can't let native English speakers listen, you can't express it in an authentic way. "Tune" refers to the changes of English syllables and their heights in discourse (called "rhythm" in China's phonology book). One of the main reasons why China people don't speak authentic English is that their accent is not in place. Obviously, the main focus of pronunciation learning should be on the cavity. Besides, you have to learn the habit of native English speakers to convey information and express emotional changes in tone. This is the advanced realm of learning to speak English. If you master the above three elements, your oral English learning will definitely have a direction. It's only a matter of time before you find the right direction and keep practicing and speak fluent English! Work together!
