高三英语知识点1
一. 直接引语和间接引语
(一)直接引述别人的原话，叫做直接引语;用自己话转述别人的话，叫做间接引语。间接引语一般构成宾语从句。直接引语必须放在引号内，间接引语则不用引号。直接引语改为间接引语时，除将引语部分变成宾语从句外，还必须对直接引语中的人称、时态、指示代词、时间状语、地点状语等进行改变。
1. 时态的变化：直接引语变为间接引语时，通常受转述动词said, asked等的影响而使用过去化的时态，即把原来的时态向过去推，也就是一般现在时变为一般过去时，现在进行时变为过去进行时，等等。例如：
Tom said to me,“My brother is doing his homework.”
→Tom said to me that his brother was doing his homework.
2. 人称代词、指示代词、时间状语、地点状语等等的变化： 根据意义进行相应的变化，例如：
She asked Jack,“Where have you been?”
→She asked Jack where he had been.
He said,“These books are mine.”
→He said that those books were his.
(二)直接引语改为间接引语时，都使用陈述语序，但是因为原句的句式不同，所以变成间接引语时所用的连词会有所不同。直接引语如果是一般疑问句，用连接词whether或if;如果是特殊疑问句，则用疑问词引导间接引语。转述的动词一般用asked，可以在其后加上一个间接宾语me, him, her, us等。如：
She said,“Is your father at home?”
→She asked me if/whether my father was at home.
“What do you do every Sunday?”My friend asked me.
→My friend asked me what I did every Sunday.
直接引语如果是祈使句，改为间接引语时，要将祈使句的动词原形变为带to的不定式，并在不定式的前面根据原句的语气(即请求或命令)加上ask, tell, order等动词，如果祈使句为否定式，则在不定式前加not。其句型为：ask / tell / order someone (not) to do something. 例如：
She said to us,“Please sit down.”
→She asked us to sit down.
He said to him,“Go away!”
→He ordered him to go away.
He said, “Don’t make so much noise, boys.”
→He told the boys not to make so much noise.

一、现在分词和过去分词的构成(形式)

2.作表语
3.作宾语补足语
4.作状语
三、现在分词的用法
1. 作定语 作定语用的分词如果是单词，一般放在名词的前面。如果是分词短语，一般放在名词的后面，它的功用相当于定语从句。
2. 作表语
3. 作宾语补足语 分词在复合宾语中可作宾语补足语。可带这种复合宾语的动词有：see, watch, hear, feel, find, get, keep等。

高三英语知识点5
1. The reason why he could not go there was that his grades were too low. 他没能上电影学院是因为他的分数太低了。
该句巾的why引导一个定语从句，而that引导表语从句。
1. 句中that引导的表语从句说明主语reason的具体内容，往往被看作是固定句型：The reason is / was that clause. 当主语是reason / cause时，一般不能用because或why引导表语从句，以免造成语意重复。当主语是This / That时，可以由because / why引导表语从句。例如：One reason is that people traveled to America from all European countries.
【考例】(NMET 1999)
-- I drove to Zhuhai for the air show last week.
-- Is that ____ you had a few days off?
A. why B. when C. what D. where
[考查目标] 表语从句。
[答案与解析]A 句子的意思是“那就是你请了几天假的原因吗?”因此可知答案为why。
2. why在句中是关系副词，引导定语从句，修饰先行词reason，同时它在定语从句中作状语，此时why = for which，但要注意：关系词在定语从句中作主语或宾语时，要用关系代词that或which。
【考例】(2002上海春招)Is this the reason ____ at the meeting for his carelessness in his work?
A. he explained B. what he explained
C. how he explained D. why he explained
[考查目标]定语从句。
[答案与解析]A what，how不能引导定语从句，排除B、C两项;the reason在定语从句中作explained的宾语，可填that / which，或者也可以省略。
2. Many people who saw the film were afraid to swim in the sea when they remembered the scenes in which people were eaten by the shark. 好多看过这个片子的人一想起片中鲨鱼食人的场面.就不敢下海游泳了。
该句是一个复杂长句，从when到句子末尾是状语从句，在从句中包含一个由which引导的定语从句，修饰先行词scenes; 在前面的主句里面。包含一个由who引导的定语从句，修饰先行词people。例如：Those who want to go camping next Sunday sign your name here before class is over.
定语从句关系词的选择，要遵循“瞻前顾后”的原则，所谓“瞻前”即看前面的先行词指人还是指物;“顾后”即后面的定语从句，看关系词在定语从句中作什么成分。例如：This is the factory where he works. (状语) / This is the factory (that / which) he visited. (宾语)
