Passage 1

A new study has shown that mosquitoes can carry AIDS viruses in their bodies for a few days, but the insects do not seem to spread the virus.

In an 31 , mosquitoes that fed on

10

blood 32 with the AIDS virus were later found to have the virus in their bodies.

33 , the mosquitoes did not seem to pass

34 the virus to a sample of uninfected blood when the mosquitoes fed on that sample. Similar experiments 35 recently in South Africa have 36 the same results.

The AIDS virus can stay in a mosquito for two or three days, 37 to the experiment. While in the mosquito, the virus does not multiply. Thus, the mosquito might be viewed 38 a momentary flying syringe, that probably carries 39 too little AIDS virus to 40 the infection.

PART IV Reading Comprehension (阅读理解) (40分) Passage 1

Language isn’t the only sign of animal intelligence. A Canadian psychologist, Dr. David Sherry, has studied the remarkable memory of nutcracker, a bird that stores food,mostly pine seeds, in tiny caches, or

15

holes, in the ground. A native of western North America, one nutcracker makes 100 to 200 separate caches every day in the fall and winter. When spring arrives, the bird returns to these caches to eat the seeds.

Dr. Sherry says that months after burying the seeds, the birds remember exactly where they stored them. They fly directly to the holes with no need to hunt and peck. “These birds have a highly specialized spatial memory --- it’s amazing,” says Dr. Sherry.

Dr. Sherry says that memory in many animals is associated with an area in the brain called the hippocampus. He found that food-storing birds have a larger hippocampus than birds that don’t store food. Hippocampus damage is one sign of Alzheimer’s disease, a brain degenerative disease marked by a failing memory.

16

51.What does the passage mainly discuss?

A. Some kinds of birds have excellent memory.

B. How birds store food in the

ground.

C. How birds find their stored food.

D.Why birds like to bury seeds in the

ground.

52.Nutcracker is a kind of bird that _____.

A. stores seeds in the ground

B. sings very nicely

C.flies to north in winter days

D.works diligently

53.When spring arrives, the bird _____.

A. returns from north

B. flies back to find the stored food

C. starts to build its new home

D. becomes busy in collecting seeds

54.According to Dr. Sherry, if one’s hippocampus is hurt, he may_____ .

A. lose his ability to talk

B. become very forgetful

C. die very soon

D.become easy to get angry

55.The phrase “associated with” in the last paragraph has the same meaning as_____?

A. “linked to”

B. “covered with”

C. “located at”

D. “stored in”

Passage 2

Gordon was a 25-year-old science teacher in 1966 when he bought a brand-new car

17

Volvo P1800. Today, Gordon, now retired, still owns the same Volvo. Last March, he put the 2 millionth mile on the car.

Gordon’s vehicle hit the big 2 million at a TV ceremony held in Times Square in New York City.

To what does Gordon owe his car’s very long life?

“Volvos are very strong cars,” he said. “Also, I drive sensibly. And I take very good care of the car.”

Gordon changes the oil every 3,000 miles; uses only the same brand of oil; changes the spark plugs(火花塞)every 20,000 miles; washes the car regularly; waxes it at least twice a year; and spends a few minutes each week checking under the hood (车篷), among other things.“Being a science teacher, I have a better idea of the ways things work,”he said.

18

Gordon says the vehicle still has many of its original parts. But many parts, such as the starter motor, the brakes(刹车), and the water pump, have been rebuilt or replaced. Gordon’s 2 million miles on the road have taken him almost everywhere in the United States, as well as to Canada, Mexico, and Europe. “Whether I drive 3 million is more up to me than it is the car,” he said. “The car’s parts may be able to take it, but I’m not so sure about my own.”

56.From the passage we can guess that _____.

A. it’s very rare for a car to drive

two million miles

B. the story has been written to introduce a new car

C. there were a car show at the New York City’s Times Square

19

D. no accidents have ever taken place

with Gordon’s car

67. The main cause of the car’s long life lies in _____.

A. Gordon’s careful service

B. Gordon’s special knowledge of

cars

C. the excellent quality of the car

D. the good quality of the oil he uses

68. Which of the following statements is TRUE according to the passage?

A. All the parts of Gordon’s car

have been replaced.

B. Some of the car’s parts can last

even longer time.

C. Volvo cars are stronger than Japanese ones.

D. Science teachers can usually keep

their cars longer.

科普英语竞赛翻译

科普英语竞赛翻译中的若干问题 1.注意科技文体风格,使用科技英语语言 科技文体的特点是结构缜密、概念准确、行文流畅、逻辑性强,词语的专业性强而修饰性较弱。在词汇方面,科技英语大量使用名词化结构和动词的非限定式,即分词、动名词和动词不定式;词汇的组成可分三类:一是被赋予新义的常用词,二是从拉丁语、希腊语等外来语中借用的词汇,三是新造词。在语法方面,科技英语多用现在时(尤其是一般现在时)、被动语态、非人称主语及定语从句。科技文体是比较正式庄重的文体。 译文能否体现科技文体的特色,关键是译文中的词汇、语法、句法结构等是否与原文中的诸因素契合一致。 1)辨析文体色彩 词汇是文章最基本表现材料,文章的总体风貌必然反映在词汇上。翻译中的选词是否准确直接关系到译文能否体现原文的总体风貌。 The agenda of ongoing work in the social and behavioral sciences has been revealed here in only the most fragmentary way. But I hope these fragments will provide some glimpse into the excitement and significance of the whole. 关于在社会和行为科学中我们目前正在搞的工作的进程,在这儿只是以很不搭界的方式摆出来的;可是我希望这些拉拉杂杂的东西倒能使读者见识一下我们整个的研究工作是多么有趣又是多么有意义。 这里展示的并非社会科学和行为科学的总体现状,只不过是让读者见其一斑。然而,笔者希望这零散材料能引起人们的兴趣,使之对全部工作的重要意义有个概略的了解。 2)理清学科归属 英语词汇的突出特点表现为一词多义。一个常用词的词义可以依据其所处的不同上下文辐射到各个不同的学科,形成一个语意辐射圈。随着社会的进步、科学的发展,越来越多的词被赋予新义,其语义辐射范围也随之扩大。译者首先应明确原文所涉及的学科范畴:是数学、物理学、化学还是医学…… They made their base at Cape Evans and planned the journey

第九届初中生科普英语竞赛辅导材料 科普类阅读答题方法及策略一 【题型说明】科普知识类文章的特点是科技词汇多,句子长且结构复杂,理论性和逻辑性又都较强,再加之文章所介绍的知识对于同学们来说是比较陌生的。因此,同学们看这类文章觉得是雾里看花。 【文章特点】科普类文章的主要特点: 1. 文章中词汇的意义比较单一、稳定、简明,不带感情色彩,具有单一性和准确性的特点。综观整篇文章可以明显看出,它没有文学英语中常采用的排比、比喻、夸张等修饰手段,一词多义的现象也不多见。 2. 句子结构较复杂,语法分析较困难。为了描述一个客观事物,严密地表达自己的思想,作者经常会使用集多种语法现象与一体的长句。 3. 常使用被动语态,强调动作的承受者。 4. 常使用双重否定句。 【结构特点】科普知识类文章结构一般也是由标题(Headlines),导语(Introductions),背景( Background),主体(Main body)和结尾(Ends)五部分构成。标题是文章中心思想高度而又精辟的概括,高考这类阅读理解材料一般也不给标题,而要同学们选择标题。导语一般位于整篇文章的首段。背景交待一个事实的起因。主体则对导语概括的事实进行详细叙述。这一部分命题往往最多,因此,阅读时,同学们要把这部分作为重点。结尾往往也是中心思想的概括,并与导语相呼应,命题者常在此要设计一道推理判断题。 【备考提醒】要做好这类阅读理解题,先要掌握这类文章的特点和结构,真正读懂并理解它。其次,工夫在课外,平时一定要多读科技幻想类文章,比如:太空与海洋、创造与发明、计算机发展、人类未来、动物世界等。特别是从网上搜寻一些取材原版、内容时新、语言鲜活的科技幻想类材料阅读。这样长期坚持,既可以增长知识、开阔视野,又可以扩充科技词汇,还能提高解答这种类型试题的能力。我们何乐而不为呢? 【实例分析】阅读下面的文章,然后做后面的阅读理解题: Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs.

科普英语竞赛辅导资料 英语科普阅读的方法与实例 一、考点描述科普类文章是英语的常考题材,每年都有所涉及,如2005年的江苏卷在五篇阅读文章中就有两篇是关于科普文章的阅读。因此,同学们在平时的学习中一定要对此引起高度的重视。 二、材料特点这类文章的总体特点是:科技词汇多,句子结构复杂,理论性强,逻辑严谨。具体说来它有以下几个特点:1. 文章中词汇的意义比较单一、稳定、简明,不带感情色彩,具有单一性和准确性的特点。这类文章通常不会出现文学英语中采用的排比、比喻、夸张等修辞手法,一词多义的现象也不多见。2. 句子结构较复杂,语法分析较困难。为了描述一个客观事物,严密地表达自己的思想,作者经常会使用集多种语法现象于一体的长句。3. 常使用被动语态,尤其是一些惯用被动句式。 三、命题特点科普类阅读的主要命题形式有事实细节题、词义猜测题、推理判断题以及主旨概括题等,其中推理判断题居多。 四、应对策略1. 要想做好科普英语阅读理解题,同学们就要注意平时多读科普知识类文章,学习科普知识,积累常见的科普词汇,从根本上提高科普英语的阅读能力。2. 要熟悉科普类文章的结构特点。科普类文章一般由标题(Headlines),导语(Introductions),背景( Background),主体(Main body)和结尾(Ends)五部分构成。标题是文章中心思想高度而又精辟的概括,但根据历年的真题情况来看,这类阅读理解材料一般不给标题,而要同学们选择标题。导语一般位于整篇文章的首段。背景交待一个事实的起因。主体则对导语概括的事实进行详细叙述。这一部分命题往往最多,因此,阅读时,同学们要把这部分作为重点。结尾往往也是中心思想的概括,并与导语相呼应,命题者常在此要设计一道推理判断题。 3. 在进行推理判断时,同学们一定要以阅读材料所提供的科学事实为依据,同时所得出的结论还应符合基本的科普常识。 五、真题赏析江苏卷Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines(刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the

科普英语论文

科普英语体会 现在夜深人静,我灵感乍现:科普英语其实可以说是我的老朋友了吧。记得和它初次相识早在初中,那时的我只图个重在参与,而现在,老师们十分看重科普英语,还特地开了个研究课叫科普英语。 科普,顾名思义,指科学技术普及,是指采用公众易于理解、接受和参与的方式,普及自然科学和社会科学知识,传播科学思想,弘扬科学精神,倡导科学方法,推广科学技术应用的活动。科普英语,是指本应该人人普及的英语知识吧。 科普英语蛮有意思的,那些文章,绿色殡葬、全球变暖、节能环保、低能耗、新型能源……都是一些很潮、很值得关注的话题,也是现在这个社会所不容忽视的问题,它们正在影响我们的生活。 科普英语很难,基本上一篇文章中,除了be动词外,没有多少词是看到过的,那也就导致了文章读不懂,做题更不用说了,通过这半个学期的专项学习科普英语,我收获了不少:要关注标题,很多时候,标题是对于整篇文章的最精炼的概括;要关注每一段的第一句话,有时它是对整个一段的概述,对于理解段落有着重要的帮助;读不懂文章时,不妨先把文章放在一边,看看选择题的选项,因为是科普文章,有些题不需要看文章,也能凭实际经验选择出答案,然后再回上去看文章,这时会有个更好地理解;如果还是没有思路,那就先做下面一篇吧…… 根据以上感受,游延伸到科普英语竞赛的题目上,因为题型是固定的,初赛由改错、常识性问题、完形填空、阅读、(回答问题)等

组成——改错的句子一般都是看不懂的,但我们可以根据词性来判别,一般性都可以凭语感拿分,常识性问题比改错还要难,但是,如果关注生活,关注社会问题,了解些动物植物的常识性知识,问题也就应该不会很大,阅读嘛,靠多练习吧,(除非你把所有科普类的单词背出来),完形填空和改错的性质差不多,就是看词性,有的词性一样,那就看上下文了。总之,练习是很重要的。 还有,做这种很难很难的文章,语感是非常重要的,语感是指你在潜移默化中对某门语言学产生的感觉(feel),这种感觉并不是每个人都拥有的,一个拥有较好语感的人,在那门语言学中可以如鱼得水。那么如何才能培养语感呢?根据本人个人经验,我觉得语感是在很多年的与英语接触的过程中,因为多看了一些英语的书籍,多读了一些英语文章,多背了些英语单词而产生了一点点英式思维,然后产生的语感,这对于解题、阅读是非常有帮助的。我语感好,与老师的教育有关,读英语课文以及原版的文章,可以使你更多地了解当地人的写作特点,了解了方法,读文章就相对容易些了。 但是如果是语感不怎么好的人,可以多背些单词,尽量使自己每时每刻融入英语学习的氛围中去,坚持下去,会有效果的。 这半个学期以来,我们主要在课上做有一定难度的科普英语阅读文章,真的很难很难,我感觉语感都失效了,然而老师在让我们做之前,帮助我们先把不认识的单词挑出来一起解决,然后在自己看、做题,这样子就难度降低很多了,但是我们还要翻译部分句子,翻译句子并不是每个单独的单词会了就一定能翻译出来的,它还在于你必须
