题文

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let’s discover friction!
WHAT YOU’LL NEED:
● Soap           ● Water          ● Your hands!
WHAT TO DO:
1. Make sure your hands are dry.
2. Rub your hands together until you feel the heat of your hands.
3. Now, use soap and water to get your hands very slippery (滑的).
4. Try to make friction happen while your hands are slippery.
5. Please write down what has happened.
LET’S TALK!
Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot.
DID YOU KNOW?
1. Friction happens when you stop your fast running bike.
2. Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it.
        ?       
Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not too hot, touch the tires (轮胎) of the car before and after a short drive to see how much warmer they get from friction.

小题1:猜词题:从所在的句子:Friction happens when two things that aren’t very smooth rub together to make heat energy.可知friction是摩擦的意思。选A
小题1:文章最后一段提到:汽车,开车,摩擦手,都是摩擦错的例子。选D

据专家权威分析,试题“Have you ever rubbed your hands together when they get cold?..”主要考查你对  政治经济类阅读,人物传记类阅读,历史文化类阅读,人生感悟类阅读  等考点的理解。关于这些考点的“档案”如下:

政治经济类阅读人物传记类阅读历史文化类阅读人生感悟类阅读

考点名称:政治经济类阅读

  • 政治经济类阅读:
    该类文章时代气息浓郁,语言鲜活,但熟字新义词、超纲词及专业词语多,长句、难句多。
    政治类文章大多数是同学们感性趣的内容,读起来倒有似曾相识的感觉,经济类文章读起来就像是雾里看花,文章看完,一头雾水。
    再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨,同学们对这类题材是望而生畏。

  • 政治经济类阅读注意:
    1、要做好这类阅读,平时就要注意了解国内外发生的政治经济大事,掌握一定背景知识;
    2、对这类文章的叙述特点及内容安排有一定了解,还要扩展这方面的词汇;
    3、阅读这类文章,要抓住文章的核心,即文章整体和各段主要在说什么,也要注意段落之间的逻辑关系。

    政治经济类阅读技巧:
    针对不同体裁的文章,我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式,我们可采取“顺读法”,以便抓关键语句,领会文章主旨;而经济类文章则多采用说明文形式,我们则可以采取“逆读法”,先读试题,再从文章中查找有用信息。若遇到的确难读的材料。
    1. 寻找主干:
    根据英语中五种基本句型结构,把句子中的主语、谓语、宾语、表语等主要成分找出来,其他成分如定语、状语、补语等则易于理解。找到了句子主干,句子的意思至少明白了一半。
    2. 剔除从句:
    在一个长句中可能会出现若干个从句,在理解时,如果把各个从句剔除出来单独理解,然后把大意拼凑起来,整个长句的意思就会明白六、七分。
    3. 辨别分句:
    一个长句如果是由几个并列、转折、递进、对比关系的分句组成,句中往往有表示这些分句关系的连接词,只要能弄清楚分句和分句之间的逻辑关系,再把各层分句的意思加以连贯,整个长句的句意基本上能跃然脑中。
    4. 寻找关键词:
    如果一个句子看完,一点句意的感觉也没有,下下策就是抓住句中的关键词,通过关键词大体弄懂这个长句的意思。
