二. 阅读理解：
“Cool”is a word with many meanings . Its old meaning is used to express a temperature
that is a little bit cold. As the world has changed , the word has had many different
meanings.
“Cool”can be used to express feelings of interest in almost anything.
When you see a famous car in the street , maybe you will say , “It’s cool. ”You may
think , “He’s so cool , ”when you see your favorite footballer.
We all maximize the meaning of “cool”. You can use it instead of many words such as
“new”or “surprising”. Here’s an interesting story we can use to show the way the word is
used . A teacher asked her students to write about the waterfall they had visited . On one
student’s paper was just the one sentence , “It’s so cool .”Maybe he thought it was the
best way to show what he saw and felt.
But the story also shows a scarcity of words. Without“cool”, some people have no words
to show the same meaning . So it is quite important to keep some credibility . Can you think
of many other words that make your life as colourful as the word“cool”? I can . And I think
they are also very cool.
注：maximize扩大；waterfall瀑布；scarcity缺乏；credibility 可信性；suggests暗示

阅读理解题的考查内容
作为一种综合性很强的题目，阅读理解题主要考查以下几个方面的内容：
1. 考查文章的主旨和大意。
包括对文章主题的理解，对文章中心大意的理解，对作者意图或文章中人物观点的理解，以及从文章内
容中可推断出的结论和作者的弦外之音等。
2. 考查文章的细节和事实。
包括事实识别、有关数字方面的计算或识图、排列次序等。
3. 考查对文章中词语的意思或句子意义的理解。
这些词句一般不只是体现其表层涵义，而往往具有深层意义，同学们要根据文章的上下文来判定其意
义，或根据句子的语法关系分析，并挖掘其含义。
4. 考查拟选题目的能力。
文章标题的拟选不但取决于文章的内容，而且还取决于标题的特点。英语文章标题的特点一般是省略冠
词、be动词或作定语用的人称代词，且多以短语或简单句为主。选择标题的一般原则是：一要切题，即概括
出全文的主旨；二是要简洁，即文字要简单明了。
“阅读理解”的解题步骤与思路点拨
1. 浏览全文，捕捉信息。
要求同学们通过浏览全文，把握其大意，了解作者的观点和写作意图。
2. 细读思考题，分析信息。
通读（浏览全文）短文后，已对文章或段落大意有所了解，再读思考题，对要捕捉的信息进行分析、推
理，这样便可先解答与主题思想有关的问题。然而浏览全文只能对大意有所了解，对于细节性的问题还得带
着问题通过复读方法解决。
3. 复读全文，抓住细节。
带着问题去复读，可缩小复读的范围，更便于捕捉要害的信息。复读时可边读边用铅笔做些标记，把有
关的人物、事件、时间、地点、起因（即5个W: who , what , when , where , why ）划出来。例如：凡逢
人物就圈起来，看完一数，有几个圈就是几个人，一目了然。经过这样的处理，你对文章的内容和细节便清
楚了，对其中矛盾的产生、发展和解决心里就会有底了。
另外，在复读全文时，还应非凡注重首段或每一自然段的首句，以及结尾句。因为短文的首句和首段往
往是作者要说明的对象或事件的起因；或作者阐述自己的观点；或事件发生的时间、地点与人物的联系。结
尾句、段是事件的结论或作者表达的态度、意图、目的等。这样一来便轻易抓住中心，为准确、快速地解题
打下良好的基础。
4. 解答问题，选定答案。
对那些明显的，有把握的题可以断然圈定。碰到不会做的问题可暂时不做，把每个问题阅读完毕，等会
做的题已做完，然后再回头做剩下的题目。在做题时，假如碰到困难，再重新查阅。这次复读，要针对问题
的要求，抓住重点，一次求得正确答案。
5. 再读全文，核对答案。
这是最后一步，也是重要的一步，不能疏忽。这一步骤要用全文的主题思想统率各思考题，把我们在阅
读和答题时所得到的信息归纳整理一遍后重新再读一遍短文，检查答案，看是否前后一致；意义和语言知识
是否和原文相符；是否符合逻辑等。发现前后矛盾、遗漏要点等错误，要立即纠正。
值得一提的是，改正原来选定的答案，一定要慎之又慎。因为在做过一段时间题目之后，大脑已有些疲
劳，假如不慎可能会把本来选对的题目更改错。这也就要求同学们要相信自己的第一感觉，不可轻易改动答
案。一定要有充分的理由，脑海中有那么一种“柳暗花明又一村”的感觉或者觉得眼前一亮，有种豁然开朗
的境界，这才可改动答案，否则，十之八九会将本已做对的试题改错，下场后叫苦不迭，结果却于事无补。
做阅读理解题应注重的事项
1. 忌不带问题进行阅读。
做阅读理解题时，应先把文章后面所给的考查题浏览一遍，然后带着这些问题进行阅读。边阅读边选出
考查表层情况问题的答案，从而可大大提高阅读效率。
2. 忌草率行事。
在设计理解题时，设计者往往在四个选项中设置一个似是而非的答案。这样，答案的干扰性就非凡强，
非常轻易迷惑考生。假如在发现一个看似正确的答案时就草率定案，往往会掉进设计者设置的陷阱里。处理
的方法是：对所给四个备选答案进行分析、比较，在理解阅读材料内容的基础上进行旁敲侧击，去伪存真，
方可选出正确答案。
3. 忌凭主观印象。
少数阅读不明确的题目只需根据生活常识就可选出答案，而绝大多数试题则不然，考生必须忠实于原文
来选定答案。这就要求考生在做后一种测试题时，一定要排除自身的生活经验、经历和已有的知识等主观因
素的干扰，按照文章实际反映的情况来选择答案，切不可想当然。
4. 忌囫囵定案。
所谓囫囵定案是指考生在未完全读懂文章时就匆忙将答案选定，结果往往会选错答案，等后来发现时再
作改动，结果弄得试卷非常不整洁，以致于影响自己的成绩。因此，对于尚未读懂的地方，假如时间答应的
话，一定要慢速多读几遍，仔细揣摩，直到弄个水落石出再定答案。
5. 忌忽略时间。
做阅读理解题时，要从整体上控制时间，时间的分配要根据文章的难易程度来决定。文中一两处没弄懂
的地方可以暂时放置起来，等把全部题目做完了，再回过头来处理。因为做完别的题目，自己的心情相对放
松了，这时往往会产生新的思路、新的灵感。即使做完试卷后所剩时间无几了，再把所剩下的题目猜测一下
也不晚，因为这时还有选对的可能性。
客观信息题与主观判定题例析
中考阅读理解题一般有两种层次的试题：一种是客观信息题，即从阅读材料中直接获取试题考查的要
点；另一种是主观信息题，即：试题的答案不能直接从原文中找到，必须经过推理和判定才能回答。显然，
第二种试题的难度一般大于第一种。下面就列举几种题型并举例分析其解题技巧。
（一）客观信息题
所谓“客观信息”，是指在供“阅读理解”的短文中客观存在的事实。客观信息的答案一般都可以在原
文中找到。一般来说，应在短文中找出相关信息的位置，确定试题测试的考点。当然，有的试题还得对原文
所提供的事实“去伪存真”，进行一定程度的比较，才能做出正确的选择。完成客观信息题应注重以下三
点：
1. 辨认事实，注重细节
2001年北京中考“阅读理解”题短文（A）中有这样一句话：
There would be a school party on Friday evening . The girls were talking about what they
were going to wear.
短文后设有如下一个问题：
On Friday evening there would be ______.
A. a school party
B. a school meeting
C. a sports meeting
D. a birthday party
［解题指导］此题的题干On Friday evening there would be _______. 假如与原文中叙述的事实：
There would be a school party on Friday evening. 相比较，可以说是“大同小异”。二者的差异仅是
词序不同。考生假如能正确理解原文中所叙述的事实，便不难看出空白处所缺少的正是A项：a school
party。
又如该短文叙述的另一个细节：
The party was held on Friday evening . Groups of students arrived . The music began . The
girls stood in a line on one side , and the boys on another side.
短文后有下面一个问题：What happened when the music began ? 与原文中叙述的细节The girls
stood in a line on one side , and the boys on another side. 相比较，选择项：D. The girls stood
on one side , and the boys on another side. 最为接近。答案中仅缺少短语“in a line”（站成一
列），显然，缺少这一短语，也不影响该事实的存在。
2. 同义转换，着重内涵
（1）词句同义。例如：
2000年广州中考“阅读理解”题短文（A）中有这样一句话：
If you see a shark , swim slowly for the shore.
针对这句话短文后有下面一个问题：
When a swimmer meets a shark , he should ______.
此题的答案是：B. swim slowly to the shore.
［解题指导］根据此题的答案，不难看出：原文中的条件句（If you see a shark）在问句中转换成了
时间状语从句（When a swimmer meets a shark），原文中主体的动作也由“see a shark”，转换成了
“meet a shark”，但是语意的内涵并未发生变化，属于同义句转换。其答案swim slowly to the shore与
原文中的swim slowly for the shore也完全同义。
（2）语段同义。例如：
2000年上海中考“阅读理解”题短文（A）中有这样两段话：
Sally was a college student . It was going to be her mother’s birthday soon . She
wondered what she could buy her as a present.
After she had looked for half an hour , she came into a shop that was selling cheap
umbrellas , and decided to buy one , since her mother had lost her umbrella the month before.
短文之后有下面一道正误判定题：Sally wanted to buy an umbrella for her mother.
［解题指导］
尽管原文中没有“Sally wanted to buy an umbrella for her mother. ”这句话。但是原文中提到：
Sally 的母亲快过生日了（It was going to be her mother’s birthday soon. ），她很想为母亲买件礼
物（She wondered what she could buy her as a present. ）。她后来发现商店卖伞（she came into a
shop that was selling umbrellas），而她母亲又需要一把雨伞（…her mother had lost her umbrella
the month before. ）。上述两段话所表达的内容“Sally wanted to buy an umbrella for her mother.
”一语道破。显然，二者用语虽然各异，但内涵相同，所表达的意思完全吻合。
3. 把握数据，注重推算
中考“阅读理解”中的数据推算并不要求高深的数学知识。在有关数据推算的试题中，根据短文所提供
的数据进行必要的运算时所涉及的数学知识一般都比较简单，要害在于理解原文。例如：2000年南京中考
“阅读理解”短文B中有这样一道题涉及数据推算：
I won a prize for one of my paintings when I was fourteen . That may be why I went to an
art school four years later … When I left school , I got some money . I hope to become a
full-time craftswoman.
短文后有如下一个问题：
When finishing school studies , the writer was about ______.
A. 14 B. 16 C. 18 D. 21
［解题指导］
原文中提到：作者（The writer）14岁时曾因绘画得奖（I won a prize for one of my paintings
when I was fourteen. ），四年之后进美术学校（I went to art school four years later）。不难算出
该生入校时的年龄为14＋4＝18（岁）。针对这段话，试卷所提出的问题是：作者毕业时（When finishing
school studies）的年龄是多少。尽管短文没有谈到这所美术学校的学制，但是作者毕业时的年龄一定大于
18岁，故干扰项A、B、C均应排除。于是，选择项D是唯一可选的。该校的学制为3年（18－21），也是完全
可能的。

On very cold winter days , a group of Japanese children travelled a long way and arrived
at a small island where nobody lived . After setting up a camp , they caught fish in the sea ,
and walked on the snow to find firewood ,wild fruit and fresh water . Then they made a fire to
do some cooking . They were not homeless children or modern Robinson . They were all pupils
from a primary school and campers of special “hardship camp. ”
Every year primary and middle schools in Japan organize such camps to train the children’
s spirit （精神）of bearing （忍受）hardship . Such places as thick forests and far-off
mountains are often chosen as camp places.
The Japanese education circles （人士）usually think it necessary to give children chances
of suffering hardships . Children in Japan now may hardly find times of hardships , because of
the rapid growth of national economy （经济）and improvement in the people’s living
conditions . The experts （专家）think that such hardship camps can help children learn to
live and develop in the struggle against nature in modern society.

Now satellites are helping to forecast the weather . They are in space , and they can
reach any part of the world . The satellites take pictures of atmosphere （大气）. So the
scientists there can see the weather of any part of the world and tell how the weather will
change.
Today , nearly five hundred weather stations in sixty countries can receive satellite
pictures . When they receive the new pictures , they compare （比较）them with the earliest
ones . Perhaps they may find that the clouds have changed during the last few hours . This may
mean that the weather on the ground may soon change , too . In their next weather forecast ,they
can tell people about it .
So the weather satellites are of a great help to the scientists at the station . In the
past they could forecast the weather for about 24 or 48 hours earlier. Now they can make good
forecast for 3 or 5 days . Soon , perhaps , they may be able to forecast the weather for a
week or more ahead （提前）.
