题文


It was so dark outside the car window that it was hard to see anything.
“ Can I have a carrot, Mom?” Bruce asked.
“I don’t have any carrots,” his mom said. “How about an apple?”
“No,” said Bruce. “It has to be a carrot.”
“Why do you want a carrot?” asked his mom
“You always say carrots help your eyes.” said Bruce. “If I eat one now, it might help me see in the dark.”
Would eating a carrot really help Bruce? What is special about carrots? What makes a carrot special is its color. Carrots are orange because they contain(包含) bta-carotene( 胡萝卜素). Beta-carotene is a way of saying vitamin A. Your eyes need vitamin A. It helps them work.
When light hits your eye, very small parts inside turn the light into messages. The messages go to your brain（大脑）, and then you know what you’re looking at. Your eye can only turn light into messages when it has a special chemical(化学物质). Your eyes use vitamin A to make the special chemical. Every time your eye changes light into messages, a little bit of the chemical is used up. By the end of the day, you’ve looked at hundreds of things. That uses up a lot of the chemical. Your eyes need to make more.
What should you eat if you don’t like carrots? Don’t worry. Other fruits and vegetables have vitamin A, too. The secret is in their color. Most orange or red fruits and vegetables contain beta-carotene, or vitamin A, Sweet vegetable, red peppers（胡椒）, Mangoes(芒果) are a few foods that have the same orange secret.
小题1: Bruce wanted a carrot because he thought _______.
A. he liked it
B. it could help him see in the dark
C.  it was sweet and delicious
小题2:How does vitamin A help your eyes work?
A. The special chemical can stop your eyes from using up vitamin A.
B. The special chemical is used to make Vitamin A which turns the light into messages
C. Vitamin A is used to make the special chemical which turns light into messages.
小题3: Which of the following is NOT true according to the passage?
A. Carrots are orange because they store beta-carotene.
B. Any food which is orange or red must have some Vitamin A.
C. Most fruits that are orange or red store some beta-carotene or Vitamin A.
小题4: Sweet vegetable, red peppers, and mangoes don’t have the same orange secret, do they?
A. No, they don’t.     B. Yes, they do.     C. I’m not sure.
小题5: The passage mainly tells us that _______.
A. we can’t see in the dark unless we eat many carrots every day
B. we can’t see unless we eat a lot of orange or red food every day
C. we should eat some food containing vitamin A so that we can see well

小题4:B
小题5:C


试题分析:
小题1:根据“You always say carrots help your eyes.” said Bruce. “If I eat one now, it might help me see in the dark.”可知选B。
小题2:根据When light hits your eye, very small parts inside turn the light into messages. The messages go to your brain（大脑）, and then you know what you’re looking at. Your eye can only turn light into messages when it has a special chemical(化学物质). Your eyes use vitamin A to make the special chemical. Every time your eye changes light into messages, a little bit of the chemical is used up.描述可知选C.
小题3:根据Most orange or red fruits and vegetables contain beta-carotene, or vitamin A,most不等于any,故选项B与短文不符.
小题4:根据 Sweet vegetable, red peppers（胡椒）, Mangoes(芒果) are a few foods that have the same orange secret.可知答案为肯定.英语反义疑问句的回答只依据事实来回答,故选B.
小题5:这篇短文主要描述了维生素A对我们的视力有好处,故选C.
点评：本文由一个小故事引出了对维生素A的介绍,作者重点描述了维生素A是如何对我们的眼睛产生作用的.短文最好告诉我们要多吃富含维生素食品,并介绍了一些富含维生素的食品.

据专家权威分析，试题“It was so dark outside the car window that it was hard to se..”主要考查你对  健康环保类阅读，科教类阅读  等考点的理解。关于这些考点的“档案”如下：

健康环保类阅读科教类阅读

考点名称：健康环保类阅读

  • 健康环保类阅读：
    本类型主要是围绕饮食健康、医疗卫生及环境保护等方面选取实际的材料来设题。
    体裁有记叙文、说明文、议论文和各种应用文。

  • 健康环保类阅读题答题注意事项和技巧：
    应试生态环保类题目时，在理解文章的基础上，要重点突破——归纳主旨大意技能，因为推断是以整体理解为基础的推断能力。
    1.归纳主旨大意：
    (1)寻找具体段落的中心思想的方法是：找出每小段的主题句。
    主题句通常有这样的特点：
    ①有一个话题(topic)；
    ②有阐述控制性概念，偶尔也可在一段中间；
    ③有的文章无明显主题句，主题句隐含在段意之中。这就需要读者进一步加工概括了。
    (2)寻找整篇文章的中心思想的方法建立在寻找具体段落中心的基础上的。
    应观察全文的结构安排，理解文章浓墨重笔写的“重心”，考虑文章组织材料及支撑性细节是服务于什么的，分析故事的发展结局都是围绕什么中心大意来安排的。
    (3)典型错误：
    ①忽视文章的结构；
    ②混淆了中心与支撑细节或材料的区别；
    ③忽视文章表意的倾向性；
    ④漏掉了主要的特征词。

    2.正确推理判断：
    推理判断试题要求考生尽量考虑文中全部信息或事实，在通篇理解文章的基础上领会作者的言外之意，并作出正确的推理和判断。
    (1)数据推断题
    解答此类题，关键是要善于捕捉有关数字的信息，然后在透彻理解原文的字面意义和题意的基础上，运用自己的数学知识，对其进行分析、推算，从而得出正确的结论。
    (2)知识推断题
    根据文章中所阐述的细节，运用基础知识进行分析、推敲，从而得出符合文章原义的结论的一种推断方法。
    (3)逻辑结论推断题
    根据事实、论点、例证等一系列论据材料，不是根据自己的经验、态度、观点或爱好去理解文章的内涵。
    解答这类题的前提是要首先获得短文的主题思想或列举的具体事实，然后按题意要求进行推断。
    (4)对作者态度、倾向的推断题
    作者的倾向和感情往往隐含在文章的字里行间，或流露于修饰的词语之中，因此，在推断过程中，应特别注意文中作者的措辞。

考点名称：科教类阅读

  • 科普类的阅读：
    科普类的阅读理解包含介绍科学知识、社会知识的短文。阅读这类短文时，要以事实为中心进行思考，抓住事物的特征、用途、相互关系等。
    如果是介绍社会现象的文章，要掌握所谈现象的内涵。

  • 答题技巧：
    1. 加强整体意识，把握文章的主要内容。在阅读的时候可给段落标上序号，并给重要的句子和
       关键词做上记号，尤其是各段中心句，为答题提供更快捷更多的信息源。
    2. 审清题干，发觉和把握试题中有效的提示性信息，确认命题的角度、阅读范围和答题方式。
    3. 定位阅读，强化对应意识。同时要注意原文利用和自我加工相结合。
