新GRE閱讀理解部分需要考生進行實戰練習,為了幫助大家更好的備考新GRE考試閱讀理解,下面小編給大家整理了新GRE閱讀理解模擬練習題,希望考生能夠更好的掌握解題思路。
  新GRE閱讀理解模擬練習題如下,希望能為你的新GRE考試增分。
  It is a popular misconception that nuclear fusion power is free of radioactivity; in fact, the deuterium- tritium reaction that nuclear scientists are currently exploring with such zeal produces both alpha particles 5 and neutrons. (The neutrons are used to produce tritium from a lithium blanket surrounding the reactor.) Another common misconception is that nuclear fusion power is a virtually unlimited source of energy because of the enormous quantity of deuterium in the sea.10 Actually, its limits are set by the amount of available lithium, which is about as plentiful as uranium in the Earth‘s crust. Research should certainly continue on controlled nuclear fusion, but no energy program should be premised on its existence until it has proven 15 practical.
  1. It can be inferred from the passage that the author believes which of the following about the current state of public awareness concerning nuclear fusion power?
  (A) The public has been deliberately misinformed about the advantages and disadvantages of nuclear fusion power.
  (B) The public is unaware of the principal advantage of nuclear fusion over nuclear fission as an energy source.
  (C) The public‘s awareness of the scientific facts concerning nuclear fusion power is somewhat distorted and incomplete.
  (D) The public is not interested in increasing its awareness of the advantages and disadvantages of nuclear fusion power.
  (E) The public is aware of the disadvantages of nuclear fusion power but not of its advantages.
  For the following question, consider each of the choices separately and select all that apply
  2. The passage provides information that would answer which of the following questions EXCEPT?
  A How much incidental radiation is produced in the deuterium tritium fusion reaction?
  B What is likely to be the principal source of deuterium for nuclear fusion power?
  C Why are scientists exploring the deuterium-tritium fusion reaction with such zeal?
  答案:1.C 2.AC
