Step-by-step explanation:
In the above excerpt, Amy Tan tells her feelings during her childhood about the language 'English.' She used to believe that the clarity and fluency in the English Language makes a person clearer and thoughtful in ideas. This was her belief during her childhood. As she grew up she developed a different view of English as a language. She expresses her view that her mother used to speak English which would be grammatically incorrect. At the same time, she adds that the activities which her mother was able to do were difficult for the native speaker of English do.
