1、LOOK UP,高考英语说明文阅读理解解题策略STRIKE DOWN考纲解读：阅读理解作为考查阅读与理解能力的试题，已成为历年高考英语试卷中必不可少的部分。阅读理解能力属于语言的领会能力，包括对书面语言的识别、理解、推理、判断和快速记忆等几个方面。不仅仅涉及到语音、语法、词汇这些语言因素，还涉及到非语言因素，即：阅读者对所学语言国家的社会和文化背景知识的掌握、对所读材料内容的熟悉、个人经历、生活常识、逻辑知识和语言修养等各方面。近几年英语阅读理解在高考中的比值有所增长。新闻新闻 ，广告，产广告，产品说明品说明分享经历，叙述一件事情，或表达情感论述一个道论述一个道理或表达一理或表达一个观点个观点

4、？CExams cause a lot of worry:the silence of the hall;the ticking of the clock;the confident expression of the student who has finished 15 minutes early.It therefore seems hardly surprising that those who worry about taking tests do systematically worse than those who do not.What is,perhaps,unexpecte

5、d,according to research published by Maria Theobald,is that it is not the pressure of the exam hall which causes the problem.It is the pressure of revision.Dr.Theobald theorised if anxiety was truly intervening(干预)a students ability to transfer known information from brain to paper,then those with h

6、igh levels of it would perform worse in a real exam than in a mock(模拟)or during online practice sessions.She therefore invited 309 German medical students to participate in a test which consisted of 230 questions.During the 100 days before the actual papers,volunteers used a digital-learning platfor

7、m which presented them with old exam questions and recorded their performance.They also sat a mock examination,clearly presented to them as such,40 days before the real exam.To assess their levels of anxiety,they were asked,every day for 40 days in the run-up to the real exam and also on the test da

8、y,to respond on a five-point scale to statements like,“I feel tense and nervous.”Dr.Theobald found that anxiety on the day of the test did not predict exam performance at all.What it did predict was the level of knowledge a student displayed in the mock exam and the digital-learning activities.What

9、actually hampered students,it turned out,were high levels of anxiety during the weeks before the exam took place.The greater a students anxiety in the days before the exam,the lower his or her knowledge-gain was during that period,leaving that student with less material to recall during the exam its
