高一英语下册必记知识点解析 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 国家公务员考试报名不用引号。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 可能英语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?”
老鼠的英文怎么写
→She asked Jack where he had been.
冰河世纪树懒He said,“The books are mine. ”
→He said that tho 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.
求职计划书
“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,“Plea 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 noi, boys. ”
→He told the boys not to make so much noi.
二. 各种时态的被动语态
被动语态概述
被动语态的概念:它是动词的一种形式,表示主语与谓语之间的执行或被 执行关系。主动语态表示主语是谓语动作的执行者,例如:They saw the little boy crying by the river. 被动语态表示主语是谓语动作的承受者, 例如:The little boy was en crying by the river.
被动语态的构成
被动语态的形式是由“助动词 be+动词的过去分词”构成。助动词be 随着 主语的人称、数、时态等的不同而变化。几种常见时态的被动语态形式如下:
1. 一般现在时 am/is/are + 过去分词
例如:Rice is planted in the south of China.
2. 一般过去时 was/were + 过去分词
例如:The trees were planted the year before last.
3. 一般将来时 will/shall + be + 过去分词
例如:A sports meeting will be held next week in our school.
4. 现在进行时 am/is/are + being + 过去分词
例如:Your radio is 张小栋being repaired now.
5. 过去进行时 was/were + being + 过去分词
When he got there, the problem was being discusd.
6. 现在完成时 have/has + been + 过去分词
His work has been finished.
Has his work been finished? Yes, it has. / No, it hasn’t.
fulfilled
7. 过去完成时 had + been + 过去分词
注意:
1.除了be 之外的其它系动词如 get, stay 等也可以和过去分词构成被动语 态。例如:Their questions haven’t got answered.
2. 含有情态动词的谓语变成被动语态使用“情态动词+ be + 过去分词” 结构。例如:
More attention should be paid to the old in this country. This work can’t be done until Mr. Black comes.
3. 含有“be going to”, “be to”等结构的谓语,其被动语态分别用 “be going to + be + 过去分词”和“be to + be + 过去分词” 。例如:
The problem is going to be discusd at the next meeting. All the books are to be山东的习俗 taken to the library.
4. 被动语态与系表结构的区别: “连系动词+用作表语的过去分词”构成 的系表结构,与被动语态的形式完全一样,所以应注意它们的区别。被动语态 中的过去分词是动词,多强调动作;系表结构中的过去分词相当于形容词,多强 调状态。前者通常可用by 引出动作的执行者,而后者则不可以。例如:
