Learning a second language requires hard work, good environment and application, and good native language expression.
People who are good at English are diligent students.
Short-term English training is only a stepping stone to learning English, and how to work hard when teaching a language is what it is.
There are three main obstacles. People think that their English will never be improved. First of all, their vocabulary is not enough. Second, you don't understand syntax, and the language structure has a guiding function, which can give you a path and help you judge what the other party will say next; Third, for cultural reasons, sometimes I understand every word, but I still don't understand the meaning. Cultural differences can also cause hearing impairment.
To attend the training, do you want to know what you want to achieve, or do you want to accomplish your career goals? Still need to study, go abroad or live? Short-term training is to concentrate most of your time and energy on systematically learning a second or third language, and then choose a textbook related to the goal, which should be branded and credible.
