In this essay, the author has endeavored to present a detailed review on Chern＇s article Chinese students＇ word-solving strategies in reading in English from the aspects of research methods, findings and arguments. ...In this essay, the author has endeavored to present a detailed review on Chern＇s article Chinese students＇ word-solving strategies in reading in English from the aspects of research methods, findings and arguments. We generally agree on the results she drew, which were as follows： （1） Chinese EFL learners were similar to learners from other L I language backgrounds in strategies use in reading; （2） Both high proficient learners and low proficient learners made more use of sentence-bound strategies and backward cues; （3） The use of forward cues differentiated the good learners from the poor learners; （4） The use of global cues correlated with subjects＇ proficiency level. However, there are some deficiencies as well. Chern over-emphasized the importance of guessing in reading, forbidding the use of dictionary or skipping. Therefore, she could not show the readers a full picture of how Chinese EFL learners discover meanings of unknown words in reading. Thus the author proposes that a further research should be conducted to see if other strategies will be employed in a real-life reading.展开更多
