任务型阅读（每空一词）。

      You have probably heard it before, most likely from your English teacher. If you want to become a good
writer, read good writing. Unfortunately, you may not have understood what did good to you and even what
you were supposed to get from that experience.
      As you start reading a book, poem, or story, do so with no thought at all and the experience will improve
your writing. Just read for pleasure to begin with, or to learn. As you progress through the work, think about
whether or not it is "easy" reading. Do you become so interested in the subject and flow of the writing that
you completely forget the person who wrote it, or does the composition sometimes call too much attention to
itself through words and phrases that seem out of place or unexpected? These latter situations are a chance to
learn from the writer's mistakes. In fact, the reader should not have to worry about how an author does "his
thing"... he should be able to just enjoy and learn. Every time a word strikes you as poorly chosen, stop to
consider why it has this effect. Also, do not spend a lot of time analyzing (分析) the passage but put more
efforts in enjoying it from the whole.
       Another thing I do, particularly with nonfiction (非小说) books, is to select a part to read as if it is a
completely separate work. Once again, read as a common consumer (消费者) rather than a critic (批评家).
For learning how words and phrases work together on the most basic (基本的) level, however, nothing is
more suitable than your devotion to reading poems. A poet is often trying to put a book's worth of meaning
and feelings into lines, and every side of the work shows a very close attention to craft (工艺).
       As you can see, there is no one simple way of reading to improve your writing. The key is not to make
it boring. Select authors you admire or like most, and enjoy their works as anyone else would. As long as you
are reading, you are improving yourself as a writer.
