阅读下面短文并回答问题,然后将答案写在横线上(请注意问题后的词数要求)。

     Every year in the first week of my English class, some students inform me that writing is too hard. They never write, unless homework requires it. They find the writing process painful and difficult.

     How awful it is to be able to speak in a language but not ________, especially English, with its rich

vocabulary. Being able to speak but not write is like living in a large house but never leaving one small

room. When I meet students who think they can't write, I know as a teacher my duty is to show them the

rest of the rooms. My task is to build fluency and accuracy while providing the opportunity in any writing

activity to enrich the moral and emotional development of my students. One great way to do this is by

having students write in a journal in class every day.

     Writing ability is like strength training. Writing needs to be done daily, just like exercise; just as muscles grow stronger with exercise, writing skills improve quickly with daily practice. I often see a rise in

students' confidence after only a few weeks of journal writing.

     Expressing oneself in writing is one of the most important skills I teach to strengthen the whole students. When my students practice journal writing, they are practicing for their future professional lives. They

build skills so that some day they might write a great novel, a piece of news, or the perfect love letter.
