However, some of my students are tired of doing so, thinking that it is both hard and useless. They argue that it takes a long time to recite a text from memory and text itself never appears in a test paper. In my opinion, it naturally takes time to recite a text, but it is worth doing so. When you are able to recite a text, you are sure to be familiar with the words and expressions. When you need them in reading or writing or doing exercises, they will come to your mind quickly, and so you will give quick response to all kinds of language situation. How can we say that it is useless? Besides, many students complain that they soon forget what they were once able to recite. This is true, but you don’t need to worry. While you are reading and forgetting the texts, your language level is being raised. Sure you don’t remember your Chinese texts that you once read in the primary school, but now you are able to read novels and newspaper. So, recitation of the texts will help you improve your language ability. 61. The writer often asks his students to recite the texts,_______. A.But they don’t like to do so.
