1、雅思阅读遇生词怎么猜词 在雅思阅读*中，遇到生词是很正常的，在这个时候，我们就需要去猜词了。下面就和大家分享雅思阅读遇生词怎么猜词，希望能够帮助到大家，来欣赏一下吧。雅思阅读遇生词怎么猜词一、利用定义式线索进行猜测定义是作者为了更好的表达思想，在*中对一些重要的概念、难懂的术语或词汇等所作的解释。这些解释提供的信息具有明确的针对性，利用它们猜词义比较容易。例如：Kinetic energy is the energy of moving particles. Kinetic可能是生词，由定义可知，表语是说明主语性质内容的。所以可以根据定义来猜测kinetic是一种动能。再如：Typhoons
2、are cyclones, storms with strong winds rotating around a low-pressure center. 如果cyclones是生词，推断该词义的线索就是其后面的解释“绕低气压中心形成的暴风雨”。在这种解释中定义句的谓语动词多为：be, mean, deal with, be considered, to be, refer to, be called, be known as, define, represent, signify, constitute等。二、根据进一步阐述猜测词义虽然进一步阐述不如定义那样严谨、详细，但是提供的信息足以使我
3、们猜出生词的词义。复述部分可以是适当的词，短语或者句子。例如：Experts in kinesics, in their study of body motion as related to speech ,hope to discover new methods of communications. 雅思备考,不出国考雅思有用吗逗号中短语的意思是“对肢体语言进行研究的学科”。短语与前面生词kinesics是同位关系，因此我们不难猜出kinesics指“肢体语言学”。在这种复述当中，构成同位关系的两部分之间多用逗号连接，有时也使用破折号，冒号，分号，引号，和括号等。另外同位语前还常有or, s
4、imilarly, that is to say, in other words, namely, or other等副词或短语出现。另外一种会以定语从句的形式出现如从句：Obesity, which is a medical disorder that affects approximately 20-30% of the population of the United States of America. It is an excessive accumulation of body fat that results from the storage of excess food ene
5、rgy calories in the bodys fat cells.根据生词obesity后面的非限制性定语从句which is a medical disorder that affects approximately 20-30% of the population of the United States of America. It is an excessive accumulation of body fat that results from the storage of excess food energy calories in the bodys fat cells.
6、我们可以推断出obesity的含义，即“过度肥胖”。三、根据举例猜测词义恰当的举例能够提供猜测生词的重要线索，例如：The consequences of epochal events such as wars and great scientific discoveries are not confined to a small geographical area as they were in the past.句中“战争”和“重大科学发现”是生词的实例，通过它们我们可以猜出战争，科学发现都是重要的events进而判断epochal的大致词义“重要的”。这与其确切含义“划时代的”十分接近。
7、四、根据上下文的语境关联猜测词义例如：Computers have been used for most kinds of crime, including fraud theft, larceny, embezzlement, burglary, sabotage, murder and forgery, since the first cases were reported in 1985.这句话中有许多生词出现，但通过上文的crime和murder一词，我们可以知道这些生词都是与犯罪有关的词。在考试中，就不必费心去考虑它们的具体意思，知道大概类别即可。再如：Goran fears onl
8、y one service in tennis - Michael Stichs. His toss is always the same: the straight one or the topspin. Sampras has a good serve and Becker too, but Stichs is the toughest to read.在此例中，Goran不难判断是人名。接下来我们发现大多数词是用于网球运动中的一些专门词汇，我们可以不必理会，而主要关注认识的那些词。这样能够大概理解Goran这个人，害怕某种service, 通过上下文大致可得知这是指网球运动中的一个动作(
9、比如发球、扣球等)。其实，service就是“发球的意思。从形容词straight可知Stichs发球的特点，而且他是最难预测的一个。这样一来就可以很好地把握*内容了。五、根据对比关系猜测词义在一个句子或段落中，有对两个事物或现象进行对比性的描述，我们可以根据生词或难词的反义词猜测其词义。例如：Unlike her gregarious sister, Jane is a shy, unsociable person who does not like to go to parties or to make new friends. Gregarious.对许多人来说可能是个生词，但是句中单词
10、unlike可以提示我们Gregarious和后面的词unsociable person是对比关系。分析出这种关系后，我们便能猜出Gregarious意为爱交际的。雅思阅读材料：丹麦长颈鹿向临终管理员吻别This is the touching moment a giraffe bid a sad farewell to a dying worker who had spent his entire adult life cleaning the animals enclosure at a Dutch zoo.荷兰一动物园中上演了温情一幕：维修工终其一生都在动物园为动物们清理窝棚，在他即将离
11、世之际，长颈鹿仿佛感受到了悲伤、献出给饲养员的告别之吻。The 54-year-old maintenance worker, who has terminal cancer, asked that his hospital bed be wheeled into the giraffe enclosure at the zoo.这位54岁的维修工已经癌症晚期，他请求把自己的病床带到动物园的长颈鹿生活区。In a heartbreaking scene, one of the giraffes then approached the man, known only as Mario, and
12、gave him a tender kiss goodbye.在一幕感人的画面中，一只长颈鹿走进这位名叫马里奥的工人，然后送上了温柔的告别之吻。(It was) a very special moment. You saw him beaming.“这一刻非常奇妙，你可以看见马里奥满脸笑容。”Mario, whos mentally disabled, then asked for a moment to say goodbye to his colleagues at the zoo, where he spent the vast majority of his adult life.马里
13、奥先天智力低于常人，他在动物园工作了大半生。当时他请求和动物园的同事告别。It was very nice that we were able to work on the last wish of this man, Mr Veldboer said.Veldboer 先生说：“我们很高兴能够通过我们的努力满足他的最后心愿。”The Ambulance Wish Foundation is a charity whose volunteers specialise in taking non-mobile terminally ill patients fulfill their dying
14、 wishes.救护车许愿基金会是一个慈善组织，其志愿者专注于帮助疾病晚期、行动不便的病人实现最后的愿望。The organization was founded in 20XX by Veldboer, who also drives the companys fleet of ambulances to take patients wherever they wish to go.这一组织由Veldboer在20XX年建立的，同时他还是基金会救护车车队的司机，载着病人到所有想去的地方。Last year the charity took a terminally-ill 86-year-o
15、ld man back to his farm in Holland, to say goodbye to his ponies.去年，这一慈善组织曾帮助疾病晚期的86岁老人回到自己在荷兰的农场，和自己的小马告别。雅思阅读材料：小睡一个小时的作用有多大?The average Briton gets six-and-a-half hours sleep a night, according to the Sleep Council. Michael Mosley took part in an unusual experiment to see if this is enough.It has
16、 been known for some time that the amount of sleep people get has, on average, declined over the years.This has happened for a whole range of reasons, not least because we live in a culture where people are encouraged to think of sleep as a luxury - something you can easily cut back on. After all, t
17、hats what caffeine is for - to jolt you back into life. But while the average amount of sleep we are getting has fallen, rates of obesity and diabetes have soared. Could the two be connected?We wanted to see what the effect would be of increasing average sleep by just one hour. So we asked seven vol
18、unteers, who normally sleep anywhere between six and nine hours, to be studied at the University of Surreys Sleep Research Centre.The volunteers were randomly allocated to two groups. One group was asked to sleep for six-and-a-half hours a night, the other got seven-and-a-half hours. After a week th
19、e researchers took blood tests and the volunteers were asked to switch sleep patterns. The group that had been sleeping six-and-a-half hours got an extra hour, the other group slept an hour less.While we were waiting to see what effect this would have, I went to the John Radcliffe hospital in Oxford
20、 to learn more about what actually happens when we sleep.In the Sleep Centre, they fitted me up with a portable electro-encephalograph, a device that measures brain wave activity. Then, feeling slightly ridiculous, I went home and had my seven-and-a-half hours of sleep.The following day I went to di
21、scuss what had happened inside my head during the night with Dr Katharina Wulff.The first thing she pointed out was that I had very rapidly fallen into a state of deep sleep. Deep sleep sounds restful, but during it our brains are actually working hard. One of the main things the brain is doing is m
22、oving memories from short-term storage into long-term storage, allowing us more short-term memory space for the next day. If you dont get adequate deep sleep then these memories will be lost.You might think: Ill cut back during the week and then make up for it at the weekend. Unfortunately it doesnt
23、 work like that, because memories need to be consolidated within 24 hours of being formed.Since deep sleep is so important for consolidating memories it is a good idea if you are revising or perhaps taking an exam to make sure that youre getting a reasonable nights sleep. In one study, people who fa
24、iled to do so did 40% worse than their contemporaries.Deep sleep only lasts for a few hours. My electrode results showed that during the night my brain went through multiple phases of another kind of activity, called REM sleep.This is the phase when you are usually paralysed - so you cant move, Wulf
25、f explained. But the eye muscles are not paralysed, and thats why its called rapid eye movement sleep.During REM sleep an extraordinary thing happens. One of the stress-related chemicals in the brain, noradrenalin, is switched off. Its the only time, day or night, this happens. It allows us to remai
26、n calm while our brains reprocess all the experiences of the day, helping us come to terms with particularly emotional events.We get more REM sleep in the last half of the night. Which means that if you are woken unexpectedly, your brain may not have dealt with all your emotions - which could leave
27、you stressed and anxious. Drinking alcohol late at night is not a good idea as it reduces your REM sleep while its being processed in your body.Back at the University of Surrey our sleep volunteers had finished their second week of the experiment. What we wanted to see was the effect switching from
28、six-and-a-half hours to seven-and-a-half hours, or vice versa, would have on our volunteers.Computer tests revealed that most of them struggled with mental agility tasks when they had less sleep, but the most interesting results came from the blood tests that were run.Dr Simon Archer and his team at
29、 Surrey University were particularly interested in looking at the genes that were switched on or off in our volunteers by changes in the amount that we had made them sleep.We found that overall there were around 500 genes that were affected, Archer explained. Some which were going up, and some which
30、 were going down.What they discovered is that when the volunteers cut back from seven-and-a-half to six-and-a-half hours sleep a night, genes that are associated with processes like inflammation, immune response and response to stress became more active. The team also saw increases in the activity o
31、f genes associated with diabetes and risk of cancer. The reverse happened when the volunteers added an hour of sleep.So the clear message from this experiment was that if you are getting less than seven hours sleep a night and can alter your sleep habits, even just a little bit, it could make you he
32、althier. Have a lie-in, it will do you good - thats the kind of health message that doesnt come along very often.据英国睡眠委员会(Sleep Council)调查显示，英国人平均每天只睡6.5小时。为了验证这样的睡眠是否足够，迈克尔莫斯利医生(Michael Mosley)参加了一项不寻常的实验。近些年来，人们已经认识到了这样的事实：我们的平均睡眠时间正在逐渐减少。这一现象的原因是多方面的，其中之一便是我们所处的文化让我们觉得睡觉是件奢侈的事情，可以轻而易举地缩减。毕竟，咖啡因的功
33、能就在这儿了：把你唤回清醒的状态。然而，随着睡眠量的不断下降，肥胖和糖尿病的发病率却在大幅升高二者之间会不会有一定关系呢?我们想看看把平均睡眠时间增加一小时会有什么效果，于是邀请了7位志愿者参加我们的实验。这7个人平日的睡眠在69个小时之间。实验由萨里大学(University of Surrey)的睡眠研究中心负责主持。我们将志愿者随机分为两组，一组每晚睡6.5小时，另一组睡7.5小时。一周之后研究者对两组人的血液进行检测，并调换两组的睡眠量，原来睡6.5小时的一组多睡一小时，另一组则少睡一小时。就在我们等待实验结果的过程中，我来到位于牛津的约翰拉德克里夫医院(John Radcliffe
34、hospital)，看看我们睡觉时究竟发生了什么。在该院的睡眠中心里，工作人员为我戴上一台便携式脑电图仪。就这样，我戴着仪器半觉好笑地回到家，睡了7.5个小时。第二天，我来到医院，向卡塔琳娜伍尔夫医生询问了我的情况。首先，她指出我很快就进入了深睡眠。虽然听上去挺安详，大脑在深睡眠时其实在积极地工作，其中一件重要的事情便是将短期记忆转存到长期记忆中，从而为第二天的短期记忆腾出空间。如果睡得不够，一些短期记忆便会丢失。你也许会想：“我在工作日里缩减睡眠，到周末再补上不就行了吗?” 遗憾的是，大脑的运行机制并非如此，因为记忆需要在最初形成的24小时内得到强化。由于深睡眠对于强化记忆十分重要，复习和考
35、试前睡够觉就很有必要。在一项研究中，那些在复习和考试前没能睡够觉的学生比同龄人表现差了40%。深睡眠只能持续几个小时。我的脑电图显示，大脑在夜里经历了几个称为快速动眼睡眠(REM)的阶段。“人处于这一阶段时通常是麻痹的，所以动不了。”伍尔夫解释道。但由于这时的眼部肌肉并未麻痹，因此这一阶段的睡眠称作“快速动眼睡眠”。快速动眼睡眠时，我们的体内会发生一种奇特的变化：脑内的去甲肾上腺素(一种与压力有关的化学物质)会大量消失，使得我们能够在平静中对白天的经历进行再加工，从而更好地应对某些事件对我们造成的情绪影响。然而，无论黑夜还是白天，去甲肾上腺素只有在快速动眼睡眠中才能大量消失。由于快速动眼睡眠更
36、多地分布于后半夜，如果你在夜里突然醒来，大脑这时很有可能还没完全处理掉你的情绪，从而导致压力感和焦虑的产生。深夜饮酒可不是什么好事情，因为代谢酒精会缩短快速动眼睡眠的时间。两周后，我们的睡眠志愿者们结束了实验。我们想看看，人在少睡一小时和多睡一小时时会有哪些变化。计算机测试结果表明，少睡一个小时时，多数人在完成思维敏捷性的任务时显得力不从心。不过更有趣的还是血液的检测结果。萨里大学的西蒙阿彻博士和他的团队发现，睡眠时间的变化会影响基因的活跃程度。“我们发现一共约有500个基因受到影响。”阿彻说。“有些变得更加活跃，有些则相反。”他们发现，当志愿者的睡眠从7.5小时减少到6.5小时时，体内与炎症、免疫和应对压力相关的基因变得更加活跃，与糖尿病和癌症相关的基因也是如此。而当受试者的睡眠时间增加后，这些基因的活跃程度便减弱了。因此，实验清楚地表明，对于那些睡不够7个小时的人而言，如果他们能够改变睡眠习惯，哪怕只是做出一点点改变，他们的身体都会变得更健康。“多睡会吧，对你有好处。”遗憾的是，这样的建议我们听到的太少了。
