Step 1 Introduction
2007年海南省高考英语阅读理解题的考查目的:
高考阅读理解要求考生在20分钟左右的时间内，完成对四篇不同题材、体裁文章的理解。另外，还增加了七选五。要求考生在10分钟左右的时间内，完成对一篇文章有关信息的筛选和匹配。阅读理解考查的不仅是考生对整篇文章的把握能力，还考查了他们快速捕捉信息、准确理解特定细节以及复杂句子的能力；考生不仅要理解文章的表层意思，更重要的是要通过文章的表层去合理推断、挖掘文章的隐含意义、延伸意义。这是对考生能力、智力、心理的一个综合检验。阅读理解的好坏在很大程度上决定着英语考试成绩。 20013年海南省高考英语阅读理解题的命题形式 高考阅读理解试题的类型主要分为四种：细节理解题、推理判断题、猜测词义题和主旨大意题。它们常见的提问形式如下： (1)猜测词义题常见的提问形式
The underlined word “hit”( in paragraph 1) probably means___ What does the underlined part“reimburse you” probably mean?
By saying “it is all worth it” in the last paragraph ,the author means that ______ (2)主旨大意题常见的提问形式
What is the main idea of the passage? The best title for the passage might be____ The main purpose of the passage is to _____ The passage mainly tells us /is mainly about___
Step 2 Main content
1. 如何进行词义的判断，做好语意理解题 策略指导：首先从词汇所处的语境进行分析，注意上下文之间的关系，如：如果出现that is, that is to say或破折号等，我们可以断定，后面的内容是对前面内容的解释；如果出现转折词but,
第 1 页 共 5 页
however, yet以及表示相反结果的on the contrary, on the other hand等，我们可以从所给内容相反的意义去考虑。 【技巧总结】高考语意判断题很多都是考查旧词新义的理解。因此大家需把词汇或短句的字面意义与语境和上下文结合起来，选择最切合文章内容，最符合上下文逻辑的意义，切忌望文生义。
2. 如何抓住文章的中心和主线，做好主旨大意题
策略指导： 读完一篇短文后应有意识地回味一下文章的大致内容，理一理文章的脉络，体会一下段与段之间的内在联系，这样做文章的中心一般都能概括出来, 涉及文章主旨大意方面的题目自然会在头脑中由模糊变清晰。 【技巧总结】我们在归纳文章主题时，一定要注意选项的内涵和外延必须能恰如其分地概括文章的主题，既不能范围过大，也不能把某一细节或侧面误当作主题。阅读时我们还应注意捕捉文章出现频率较高的中心词汇以及文章和段落的主题句。在选择文章题目时，还应注意语言方面的特点：文章题目往往具有凝练、醒目的特点。 3 猜测词义题
猜测词义是从特定的角度考查考生的阅读理解能力和处理生词的能力。猜测词义包括对词、词组和句意的理解，是高考英语试题阅读理解中的一类必考题。猜测词义题常见的解题方法： （一）上下文线索猜测词义
任何一篇文章中的句子在内容上都不是绝对孤立的，都跟句子所在的段落及整篇文章有关。利用上下文提供的情景和线索，进行合乎逻辑的综合分析而推测词义，是阅读过程中的一大关键，也是高考的热点。
如：If he thinks he can invite me out, he is all wet. I don’t like to be with him. A. drunk B. sweating C. happy D. mistaken
分析：根据I don’t like to be with him我们感受到说话人的语气。我不愿意跟他在一起，那么，他要邀请我出去是不可能的 他就大错特错了。因此答案D。 （二）根据定义或解释猜测词义
阅读文章中的有些生词尤其是新闻报导及科普类文章中的生词，往往在其后有对该词进行解释说明性的短语或句子，如to be, that is , mean, stand for, namely, to refer to, to mean ,in other words等，有时也以同位语、定语从句的形式出现，或用破折号、括号来表示。
如：Some ships carried cargo such as coal, oil and military supplies(军用物资),while others carried only passengers.
分析：such as后所列举物品均为“货物”，由此推断cargo的意思相同，和后面的passengers形成对比。
（三）. 根据反义词或反义关系
有的文章作者为了增强表达效果，会用一对反义词揭示事物的不同点，形成鲜明的对比，这时只要把握其中的一词，就不难推出另一词的含义，这种句子多见unlike, although, but, yet, while, on the contrary, on the other hand, for one thing, for another, instead of, rather than等信息词。如：One idea about business is that it can be treated as a game of perfect information. Quite the reverse, business polite, life itself is games which we must normally play with very imperfect information. A. Quite right. B. Time enough. C. Most unlike. D. Just the opposite.
第 2 页 共 5 页
分析：由前句中perfect information到后面imperfect information这一组对比关系的词，我们可以推断应为“对比、相反”的意思。 (四). 根据同义词或近义词关系
常见的引出同义词的标志性词语有or, like, similarly等。如：
Millions of animals die each year on Us roads, the Highway administration reports. In fact, only about 80 ocelots, an endangered wild cat exist in the US today. The main reason? Roadkill. 分析：从后面的同位语an endangered wild cat可知“ocelot”是一种野生猫 （五）利用例证性线索
某些冷僻的词汇后面会举一个例子，使词汇具体易懂。等连接性词语往往用来举例说明前面较难理解的名词。 如：You can take any of the periodicals: The World of English, Foreign Language Teaching in School, or English Learning. 分析：通过后面的例子：《英语世界》、《中小学外语教学》、《英语学习》，可知periodicals为“期刊杂志”
（六）根据构词法猜测词义
阅读中常会遇到一些由所熟悉的单词派生或合成的新词，可利用构词法知识来推测其意思。 如：Exhibition officials said that a person bitten by one of these snakes would need at least 80ml of an anti-poison medicine to be saved.
分析：anti—poison 是由poison加前缀anti-构成的，anti-意思是“反对、排斥、抵抗”，由此可猜出anti-poison是“解毒、抗毒”的意思。
5. 结构复杂的长句子出现在阅读理解中往往造成大家心理上的紧张，有时读了好几遍还不知道句子的意思，白白浪费了时间,如何对待阅读理解中的长句子? 策略指导：阅读理解中的结构复杂的句子一般分为两大类：第一类是由复合句或并列句构成的长复杂句子；第二类是省略句。对于第一类句子，大家应抓其主干成分，理解其主体意思，其他的成分都是对主体意思的修饰和补充。对于第二类句子，大家应通过上下文找出省略成分，把句子补充完整。 【技巧总结】结构复杂的句子往往出现在说明文或议论文中，这是造成考生心理紧张的主要原因。大家应冷静下来，结合文章所说明或议论的中心话题，抓住主干，层层理解。 下面结合2007年广东高考阅读理解试题，具体分析对这些能力的考查：
C
Malaria, the world's most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year ---- almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating

the red blood cells they infect (感染) .They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
51. According to paragraph I, many people don't seek care because . A. they are too poor B. it is unusual to seek care
C. they can remain unaffected for long D. there are too many people suffering from the disease 52. People suffering from malaria .
A. have to kill female mosquitoes B. have ability to defend parasites
C. have their red blood cells infected D. have sudden fever, followed by chills 53. Which of the following may be the reason for the wide spread of the disease?
A. Its resistance to global warming. B. Its ability to pass on the virus frequently. C. Its outbreaks in cities with large populations. D. Its ability to defend itself and resist new drugs. 54. It can be inferred from the passage that . A. no drugs have been found to treat the disease
B. the alternative treatment is not easily available to most people C. malaria has developed its ability to resist parasites
D. nobody knows what will be the drug to treat the disease
55. Which of the following questions has NOT been discussed in the passage? A. How can we know one is suffering from malaria? B. How many people are killed by malaria each year? C. Why are there so many people suffering from malaria? D. What has been done to keep people unaffected for long?
[导读] 这是一篇介绍医学科普常识的说明文。本文主要介绍疟疾病的起因、传播、危害与治疗。疟疾（Malaria）是世界上传播最广泛的寄生虫引起的病，每年都要使三百万人致命——几乎全是5岁以下的孩子，并且是贫穷的非洲人。疟疾病本身有很多基因，对于各种新药物具有抵抗性，所以目前还没有找到根治疟疾病的最佳治疗方法和药物。 Keys: 51-55 ACDBD

51. A。细节事实理解题。见第1段第2-3句：... because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. (多年来，有5亿多病例由这种病引起的，虽然确切的数字难以估计，) 因为许多人不去寻求（或不可能）医疗护理。这种情况对于一个年收入不到200美元的家庭并非不同寻常，因为要治疗疟疾病， 就花去年收入的四分之一，并且他们时常所得到的不再有效。 52. C。细节事实理解题。见第2段第3句：Malaria parasites live by eating the red blood cells they infect (感染) .疟疾寄生虫依靠吃他们感染的红血球生存。这说明疟疾病患者的红 血球受到感染。
53. D。细节事实理解题。这种疾病之所以广泛传播是因为它有一种自我防御和抵抗新药物的能力。见第2段倒数第3句：Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control.。 54. B。推理判断题。根据第3段倒数第2句：Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. 一些成功的可供选择的化学药品在阻止疟疾的这种抵抗力方面已经出现效用，但是这些可供选
择的化学药品非常短缺，并且昂贵，因此大多数人不容易得到可供选择的治疗。 55. D。细节事实理解题。A项见第2段第1句：Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches；B项见第1段第1句：... kills as many as three million people every year almost all of whom are under five, very poor, and African.；C项见第2段第3句：Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control.；又见第1段第2 句：... because many people don't (or can't) seek care.；D项没有提到。
