The people were asked if the objects could be found inside the hou， or outdoors．Then some of the subjects were given a caffeine pill．The others were given a placebo—a pill containing nothing. 24 hours later，the subjects were shown the exact same images from the day before．They were also shown images with slight differences，and some completely new images. Both groups correctly identified the exact same and completely new pictures．But tho who took the caffeine pill were better at spottingthe pictures that were slightly different．Professor Yassa says their answers helped to show the effects of caffeine on memory. And  we find that if they are on caffeine they are much more likely to make the right decision．”The amount of caffeine the rearchers ud in the study was similar to one cup of strong coffee．The rearchers did not e any improvement to memory from smaller dos of caffeine or when it was given an hour before viewing the images．小题1:What is the focus of the text?   A．Caffeine can make people addicted．B．Caffeine can make people energetic.C．Caffeine can improve long—term memory．D．Caffeine can make people feel comfortable．小题2:What does the third paragraph mainly talk about?A．How the experiment was conducted．B．Who took part in the experiment．C．Which group of subjects did better．D．What was ud in the experiment．小题3:In which ction of a magazine can we read this text?A．Culture．B．Technology．C．Health.D．Education.小题4:Which of the following statements is NOT true?A．Most forgetting occurs within the first 24 hours．B．Forgetting can be positively affected by caffeine．C．The subjects were given different pills．D．Yassa was disappointed with the result．小题5:What can we learn from the last paragraph?A．More caffeine means better memory．B．Smaller dos of caffeine doesn’t work．C．The time to take cafieine doesn’t matter．D．Caffeine is taken before the experiment． 题型：未知难度：其他题型

答案

小题1:C小题2:A小题3:C小题4:D小题5:B

解析

本文主要告诉我们咖啡因除了可以振奋我们的精神以外，对我们的长期记忆也是有很好的促进作用，文章中作者列举了与此有关的一个实验的情况。小题1:C 【试题解析】主旨大意题。根据文章第一段最后一句This is becau of caffeine，which helps to give a jump start to the nervous system．Now，a report says it may also boost long-term memory．可知本文主要讲述的是咖啡因能够有助于人们的长期记忆，叙述与此有关的实验的情况。故C正确。小题2:A 【试题解析】推理题。根据本段2,3行Then some of the subjects were given a caffeine pill．The others were given a placebo—a pill containing nothing. 24 hours later，the subjects were shown the exact same images from the day before．可知本段是在叙述这个实验的具体流程和做法，所以本段是关于实验如何被操作的。故A正确。小题3:C 【试题解析】推理题。本文主要讲述的是咖啡因不仅可以让我们的精神兴奋起来，而且对我们的长期记忆也是有很大的好处的，所以本文是关于健康类短文短文，也就是说C项正确。小题4:D 【试题解析】推理题。根据倒数第二段Professor Yassa says their answers helped to show the effects of caffeine on memory. And  we find that if they are on caffeine they are much more likely to make the right decision．可知他认为这个研究的结果能够反应咖啡因对人的记忆的影响，说明这个实验是有作用的。也就是说D项说法是错误的。小题5:B 【试题解析】推理题。The rearchers did not e any improvement to memory from smaller dos of caffeine or when it was given an hour before viewing the images．可知剂量较小的咖啡因对人的记忆没有太多的改善，这样的研究在实验里没有体现出来。故B正确。【长难句解析】Many people cannot start their day without first having a cup of coffee or tea。【翻译】如果没有一杯咖啡或者一杯茶，很多人都无法开始一天的工作。【分析】本句中的介词without如果没有…；表示上下文的条件，相当于一个条件状语从句：if  they don’t have a cup of coffee or tea.

考点

据考高分专家说，试题“Many people cannot s.....”主要考查你对 [日常生活类阅读 ]考点的理解。 日常生活类阅读

日常生活类阅读的概念：

日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。

日常生活类阅读题答题技巧：

【题型说明】该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。 【备考提醒】为了保证较高准确率，建议同学们做好以下几点： 1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。 2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。 3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。 4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
