First of all, if possible, try to stay in joint ventures or foreign companies for a period of time, where there are usually foreign colleagues. Usually meetings, discussions and even daily greetings will use English, which will automatically create an English-speaking atmosphere and help you improve your spoken English unconsciously. Moreover, the daily letters and written materials of these enterprises are in English, which is very helpful to improve their English understanding.
Secondly, improve your vocabulary. Usually when we communicate with foreigners, we can clearly hear each other's pronunciation, but we just don't know the meaning of this word, which means that our vocabulary is too small.
On the way to and from work, you will often see many dictionaries, scallop words, fluent English and other apps. On their mobile phones, they whisper, recite words or read short sentences. This is also a way to improve your vocabulary. If you persist for half an hour 15 minutes every day, you will find great changes, and the words and phrases you used to listen to will soon know their meanings, just like certain Chinese vocabulary.
Finally, after you have a certain vocabulary, you need to create a certain language environment, that is, to improve your oral English through communication. Many people want to learn spoken English well first, and then find a foreign company. A good way is to participate in online and offline oral English training. Training is a one-to-one or many-to-one teaching guidance for foreign teachers every day. Office workers usually don't have much time to participate in offline oral training, so they can take online oral training courses.
In fact, through the above three stages of exercise and study, you can not only speak English fluently, but more importantly, you can greatly improve your self-confidence and make yourself no longer contradict English, which will have a great impact on your future career and life.
