阅读下面短文,并根据要求完成文章后的题目。

【1】The other day my cousin sent me a message asking me, “How can I improve my English ?” I shut my eyes for a few seconds, during which, my mind went back to the early 90s when I was a ninth grader.

【2】Our English teacher was Mrs. Dubei at that time. She was a small, round woman with white and grey hair. As a loud woman she made her presence felt everywhere. Whether in the classroom, during a discussion, or just when greeting us, she would stop to ask us how much reading we had done on that particular day. She always advised and encouraged us to read, read and read. It didn’t matter whether it was an article, a page form a novel, or just a paragraph from a school magazine. She would always urge (力劝) us to "read, read and read" in order to learn new words and use them in our daily writing and conversation.

【3】Today, I feel strongly that it was because of the continuous, strong support of my English teacher that ________________. “You needn’t be a bookworm,” she would say. “Read, so that you can move ahead and journey into the depths of knowledge.”

【4】In addition to my teacher’s advice, my most important secret of learning English is: Don’t be in too much of a hurry. You are setting off on a long journey and there will be delays(耽搁) along the way. You should stick to it and take your time to really enjoy the happiness that English can bring.
