1.Read the passage carefully and find out the sentences describing the writing system of the Maya people.
It contained more than 800 characters,with some signs representing animals, people and objects and others representing syllables.It was a writing system so complicated that,so far,no one has been able to interpret it completely.
2.Read the passage carefully and find the sentences describing how the Maya people played a part in their downfall.
They had turned wetlands into fields for growing grains,and had dug huge canal systems.As their population expanded,yet more land was needed for agriculture and more trees for construction.By changing the landscape in this way,it is possible that the Maya people unknowingly reduced their ability to deal with natural disasters.

语法精讲
一、名词性从句的概述
在复合句中起名词作用的从句叫名词性从句,包括主语从句、表语从句、宾语从句和同位语从句。
二、引导名词性从句的引导词
连接词:that,whether,if
连接代词:what,which,who,whom,whose,whatever,whichever,whoever,whomever
连接副词:how,why,when,where,however,whenever,wherever
三、名词性从句的基本用法
1.连接词that,whether和if的用法
(1)连接词that的用法
that引导名词性从句不作任何成分,没有任何意义,只起连接作用。
It is required that the theme should be about nature.(主语从句,不缺成分和语义)
要求主题应该是关于自然的。
I followed his advice that I should enrich myself by doing things like reading and writing.(同位语从句,不缺成分和语义)
我听从了他的建议,我应该通过做像阅读和写作这样的事情来充实自己。
【名师点睛】
that引导及物动词后的宾语从句时,可以省略。
(2)连接词whether与if的用法
whether和if引导名词性从句在句中不充当句子成分,含有“是否”之意。
当it作形式主语,主语从句放在后面时用whether或if引导均可,在及物动词后面的宾语从句可用whether和if,其他情况只用whether,不用if。
Shennong walked in the field and tasted various kinds of plants to see whether/if they could be used as food or medicine.
神农走在田野里,尝了各种植物的味道,看它们是否可以食用或药用。
Whether the meeting will be held is still a problem.
是否要开会仍然是个问题。
2.连接代词的用法
从句中缺少主语或宾语时,选择以下连接代词:what(ever),which(ever),who(ever),whom(ever)。通常情况下,which是在语境中提供了范围才会使用,否则,指事物时使用what(ever)。
While studying,fix your mind on what is really important,or you will end up remembering nothing.(宾语从句,what在从句中作主语)
学习的时候,把注意力集中在真正重要的事情上,否则你就会什么都记不住。
The employers often give the job to whoever they believe has work experience with a strong sense of duty.(宾语从句,whoever在从句中作主语)
雇主们经常会把工作给他们认为有工作经验并且有强烈责任感的人。
Whichever team wins on Saturday will go through to the national championships.(主语从句,whichever在从句中作定语)
无论哪个队在星期六获胜,都将进入全国锦标赛。
3.连接副词的用法
从句中不缺少主语或宾语,而是缺少状语,此时则用when,where,why,how等带有语义的连接副词。
It can be especially difficult to know where the line is when it comes to the Internet.(宾语从句,where在从句中作状语)
当涉及互联网时,要知道界限在哪里可能尤其困难。
【名师点睛】
单个的主语从句作主语时,谓语动词用单数形式。如果是两个或两个以上的主语从句作主语,谓语动词则用复数形式。
Where and when he was born has not been found.
他出生的地点和时间还没有找到。
When the person was murdered and why he was murdered are still unknown.
这个人什么时候被谋杀,为什么被谋杀,现在还不清楚。
4.as if/though和because引导的表语从句
It seems as if/though the noise comes from downstairs.
噪声似乎是从楼下传过来的。
四、名词性从句的疑难点
1.that与what引导名词性从句的区别
that在从句中不充当句子成分,也没有含义;what可以在从句中作主语、表语、宾语和定语,意思是“什么,什么……的事情,什么样的”。
Our teacher made a request that we(should) be well prepared for the exam.
老师要求我们为考试做好充分准备。
We had to write a paper on how we plan to apply what we would learn in class to our future professions.
我们必须写一篇论文,内容是我们打算如何将课堂上学到的知识应用到未来的职业中。
2.wh-与wh-ever引导名词性从句的区别
连接词what,which,who分别表示“……的东西或事情”“哪一个”“谁”,表示疑问含义;而whatever,whichever,whoever分别相当于anything that,any...that,anyone who,意为“无论……”,强调一切情况。试比较:
What you choose to wear should be clean.
你选择穿的衣服应该是干净的。
Whatever you choose to wear should be clean.
无论你选择穿什么,你的衣服应该是干净的。
3.表示“要求,建议,命令,坚持”的词后跟名词性从句时,从句中的谓语动词用“should+do”,其中should可以省略。
The teacher made a suggestion that she (should) apologise to her deskmate for her bad behaviour.
老师建议她为自己的不良行为向同桌道歉。
The game is so significant that it is required that everyone (should) present themselves punctually.
这场比赛意义重大,要求每个人都要准时到场。
4.宾语从句的时态
(1)主句的谓语动词如果是一般现在时或一般将来时,从句的谓语动词可用任何所需要的时态。
He says that he studies at school from Monday to Friday.
他说他从周一至周五都在学校学习。
I know that she didn’t tell you that she would go to America next month.
我知道她没有告诉你她下个月要去美国。
(2)主句的谓语动词是一般过去时时,从句的谓语动词通常用相应的过去时。
The boy said that there were no classes on Sunday afternoon.
那个男孩说周日下午没有课。
My Chinese teacher asked me if I was reading the book Red and Black when he came in.
我的语文老师问我他进来时我是否在读《红与黑》这本书。
(3)如果从句表示客观事实或真理,不管主句的谓语动词是何种时态,从句都要用一般现在时。
As a child,I was told that the moon has no light of its own.I didn’t believe it.
孩提时,人们告诉我月亮自身不会发光,我不相信。
