專四閱讀理解技巧一、略讀 skimming，英語專四閱讀時，想要提速就要在閱讀時注意抓住重點，比如每篇文章的首段和末段、每段的首句和末句，這樣會大大提高閱讀速度。另一方面，考生不要緊張，只要全神貫注地答題就能快速準確地找出答案。例如：
  First read the following question.
  The general idea of the passage is why the U.S. ______.
  A. made atomic bombs
  B. used atomic bombs
  C. invaded Japan
  D. accepted Japan’s surrender
  Now skim the passage below and answer the question.
  The decision to drop the atomic bombs, once the scientists had developed them, was not lightly made. Operating without knowledge of the highly secret scientific breakthrough, allied military staffs planned to invade Japan in November, 1945, with a second major landing in March, 1946. Japanese resistance in the Pacific islands had been so fierce that the Allied planners anticipated more than a million Allied and two million Japanese casualties. President Truman’s hope was that the atomic bombs—through a demonstration of immense power—would shock the Japanese command into accepting the idea of surrender and save lives on both sides.
  根據前面章節(jié)所介紹的有關解答主旨題的方法，考生可以很容易發(fā)現文章最后一句話是主題句，這就是文章的大意，因此正確答案為B。
