题文

Some people can stay up all night and still get work done the next day.I'm not one of them.After a night without enough sleep, I feel badtempered.I have trouble remembering things.And all I want to do is to crawl into bed and sleep.How do you feel after you've stayed up late to finish schoolwork? Or the day after an overnight party? Scientists now say that your answers to the questions may depend on your genes.New rearch suggests that a gene called “period 3” affects how well you function without sleep.The “period 3” gene comes in two forms：short and long.Everyone has two copies of the gene.So, you may have two longs, two shorts, or one of each.Your particular combination depends on what your parents pasd on to you.Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of “period 3”．Study participants had to stay awake 40 hours straight.Then，they took tests that measured  how quickly they pushed a button when numbers flashed on screen and how well they could remember lists of numbers.Results showed that the people with the short form of “period 3” performed much better on the tests than the people with the long form did.In both groups，people performed worst in the early morning.After the first round of experiments，participants were finally allowed to sleep.People in the group that performed well on the tests (tho with the short form of “period 3”) took about 18 minutes to nod off.People with the long “period 3” gene, by contrast, fell asleep in just 8 minutes.They also spent more time on deep sleep.That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.I think I must have the long form of“period 3”．What about you?小题1:The purpo of this passage might be________.A．to tell us the importance of plenty of sleepB．to tell the result of a rearch on sleepy geneC．to inform the harm of lacking sleepD．to announce the sleeping rules of humans小题2:Which of the following decides how well you perform without sleep? A．One short form.B．One long copy.C．One short and two long copies.D．Period 3.小题3:What kind of people need less sleep according to the rearch?A．Tho with two long copies of the gene.B．Tho with two short copies of the gene.C．Tho with one short and one long copy of the gene.D．Tho with three short copies of the gene.小题4:If one lacks enough sleep，one should avoid doing important or dangerous things ________.A．at dawnB．at nightC．in the afternoonD．at noon 题型：未知难度：其他题型

答案

小题1:B小题2:D小题3:B小题4:A

解析

小题1:答案 B [主旨大意题。文章的目的就是介绍一项关于睡眠的实验结果(文章第三段为主题段)。]小题2:答案 D [细节理解题。人们缺乏睡眠时表现的好坏由“period 3”决定。根据第三段第一句话可知答案。]小题3:答案 B [细节理解题。由文章第五段可得出答案。]小题4:答案 A [推理判断题。根据第五段第二句“In both groups，people performed worst in the early morning.”得出答案。缺乏睡眠的人在黎明时表现最差，因此不能在此时做重要或危险的事情。]

考点

据考高分专家说，试题“Some people can stay.....”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。
