There are many unsolved mysteries of the natural world, of which the Bermuda Triangle is a frightening one. This area is roughly triangular in shape. Over the past several decades, at least hundreds of ships and planes and over a thousand people have disappeared. Some people think the incidents were due to aliens. Some believe they might be related to special weather there. But no one can give a powerful evidence to throw light on the incidents. It is predictable that in the future we are bound to solve the mysterious phenomenon with the development of science and technology.

提能二用课文句型解构高考长难句[本单元突破点——同位语中包含定语从句]
“自然界的未解之谜”是高考阅读理解中的常考话题。

常常停止匆匆的步伐驻足仰望，在静谧的夜空下苦思冥想，头顶的那一方无垠苍穹，究竟隐藏了多少奥秘？当遍布天体的宇宙不再只是孤独相望，当静悄悄的星体上升开始活跃生灵的迹象，对未知及自身生存的探讨似乎渐渐成了一份永恒的追问和不懈的探索。

回顾历年高考试题，有关此话题的题目通常在阅读理解中考查。

话题与语篇
[考题示例](2015·四川高考阅读E)
[1]No one is sure how the ancient Egyptians built the pyramids near Cairo. But a new study suggests they used a little rock ‘n’roll. Long-ago builders could have attached
wooden poles to the stones and rolled them across the sand, the scientists say.
[2]“Technically, I think what they're proposing is possible，” physicist Daniel Bonn said.
[3]People have long puzzled over how the Egyptians moved such huge rocks. And there's no obvious answer. On average，each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.
[4]The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect workers first would have put the blocks on sleds (滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated_the_paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand.
[5]Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.
[6]However, physicist Joseph West thinks there might have been a simpler way, who led the new study. West said, “I was inspired while watching a television program showing how sleds might have helped with pyramid construction. I thought, ‘Why don't they just try rolling the things？’”A square could be turned into a rough sort of wheel by attaching wooden poles to its sides, he realized. That, he notes, should make a block of stone “a lot easier to roll than a square”．
[7]So he tried it.
[8]He and his students tied some poles to each of four sides of a 30-kilogram stone block. That action turned the block into somewhat a wheel. Then they placed the block on the ground.
[9]They wrapped one end of a rope around the block and pulled. The researchers found they could easily roll the block along different kinds of paths. They calculated that rolling the block required about as much force as moving it along a slippery (滑的) path.
[10]West hasn't tested his idea on larger blocks, but he thinks rolling has clear advantages over sliding. At least, workers wouldn't have needed to carry cattle fat or water to smooth the paths.
1．It's widely believed that the stone blocks were moved to the pyramid site by________.
A．rolling them on roads
B．pushing them over the sand
C．sliding them on smooth paths
D．dragging them on some poles
2．The underlined part “lubricated the paths” in Paragraph 4 means________.
A．made the paths wet
B．made the paths hard
C．made the paths wide
D．made the paths slippery
3．What does the underlined word “it” in Paragraph 7 refer to?
A．Rolling the blocks with poles attached.
B．Rolling the blocks on wooden wheels.
C．Rolling poles to move the blocks.
D．Rolling the blocks with fat.
4．Why is rolling better than sliding according to West?
A．Because more force is needed for sliding.
B．Because rolling work can be done by fewer cattle.
C．Because sliding on smooth roads is more dangerous.
D．Because less preparation on paths is needed for rolling.
5．What is the text mainly about?
A．An experiment on ways of moving blocks to the pyramid site.
B．An application of the method of moving blocks to the pyramid site.
C．An argument about different methods of moving blocks to the pyramid site.
D．An introduction to a possible new way of moving blocks to the pyramid site.
[策略指导]
(一)这样读文
第1步：宏观把握文章大意
第2步：微观突破理解障碍
[自主翻译]West说，“我是在看一个展示滑板在建造金字塔的过程中可能起作用的电视节目时受到启发的。

”
(二)这样做题
[名师解题]
1．细节理解题。

选C根据第四段第一句“The most popular view is that Egyptian workers slid the blocks along smooth paths.”可知，人们普遍接受的观点是埃及人是在光滑的道路上滑动石块的，故选C项。

2．词义猜测题。

选D根据该词组所在句子的后半部分“either with wet clay or with the fat from cattle”可推知，他们使用湿的黏土或牛的脂肪使道路“变得光滑”，这样才能更轻松地移动石块。

3．代词指代题。

选A根据第七段画线部分中的“So he tried it.”中的So一词可判断，it指代的内容应该在第六段。

根据第六段中的“A square could be turned into a rough sort of wheel by attaching wooden poles to its sides ...make a block of stone ‘a lot easier to roll than a square’．”可知，物理学家West提出，在石块四周捆绑上木棒可以使石块更容易滚动。

因此他对这种方法进行了尝试，故选A项。

4．推理判断题。

选D根据最后一段最后一句“At least, workers wouldn't have needed to carry cattle fat or water to smooth the paths.”可知，用滚动的方法不需要带着牛的脂肪或水使道路变得光滑，也就是说对道路做的准备工作更少，故选D项。

5．主旨大意题。

选D文章主要介绍了古埃及人搬运巨石建造金字塔可能用的更省力的办法，故选D项。

[阅读理解系列技法17]了解“总分型”文章结构，巧解主旨大意题
总分型文章结构：即中心主题句出现在文首。

开门见山，提出主题，随之用细节来解释、支撑或发展主题句所表达的主题思想。

这是英语中最常见的演绎法写作方式。

例如上文第5题，根据题干“What is the text mainly about？”可知，本题考查的是主旨大意题。

分析文章结构可知文章第一段提出话题：对建造金字塔使用的石块的运输方式的一项新的研究。

下面文章分为两部分分说之前的研究和现在新的研究。

故正确答案为D项。

(三)这样积累
1．pyramid n．金字塔
2．roll v. 卷；滚动；转动
3．technically ad v. 技术上；专门地
4．drag v t. 拖，拉
5．evidence n. 证据，证明；迹象
6．attach ... to ... 把……系到……上
7．puzzle over 努力思考；为……烦恼
8．on average 平均；普通，通常
9．a large amount of 大量的(接不可数名词)

Ⅰ.语法填空
I'd like to say something about WeChat. Nowadays, it __1__ (become) more and more popular in China. No matter where we are, we can send text or voice messages to our friends. We can also find someone __2__ (talk) to by shaking our cellphones. And WeChat can help search for people __3__ (use) this application nearby. Many people like this function (功能), __4__ it can help them make more new friends.
All in all, WeChat is really __5__ useful chatting (聊天) tool. It allows us to communicate and share our __6__ (feel) with others more easily. However, it may also do harm to people, especially to students. As you see, some people use WeChat for too long every day, which is of course bad __7__ their health. So it is very important that we use WeChat in a correct way. While studying, we should not use it. And we must be careful not to give away too much __8__ (person) information or trust strangers so much. Or we might be easily cheated online.
In a word, we should learn how to use WeChat __9__ (proper). Remember WeChat is not everything in __10__ (you) life.
语篇解读：本文为一篇说明文。

作为一款功能非常强大的交际应用程序，微信已经被广泛使用。

但是，我们应该合理使用它。

1．is becoming根据“nowadays”及“more and more”可知，这里用现在进行时。

2．to talk“to talk to”是动词不定式短语作后置定语，修饰不定代词someone。

3．using people是动词use所表示动作逻辑上的主语，故用现在分词短语作后置定语，修饰people。

4．because/for主句和从句之间在意义上存在因果关系，故用because/for引导原因状语从句。

5．a微信是一个有用的聊天工具，故用不定冠词。

6．feelings形容词性物主代词修饰名词，故填feel的名词形式feeling的复数形式。

feeling意为“情感，感情”。

7．for be bad for ...为固定短语，意为“对……有害”。

8．personal空格中所填单词在句中修饰名词information，故填person的形容词形式。

9．properly空格中所填单词在句中修饰动词use，故填proper的副词形式。

10．your名词前用形容词性物主代词修饰。
