1、Unit 3:Could you please tell me
where the restrooms are?
第三单元的语法重点是:宾语从句;语态;倒装句;程度副词。
宾语从句
连接代词和连接副词引导的宾语从句。
1. 由连接代词 who, whom, whose, what, which 等引导,不能省略。例如:
Do you know who he is?
2. 由连接副词 how, where, when, why 引导, 也不可省略。例如:
I don't know where I can buy this kind of camera.
2、
3. 宾语从句用陈述句语序,即:连接词 + 主语 + 谓语 + 其他。
4. 主句与从句的时态关系:
(1) 如果主句是一般现在时,从句可以是根据情况所需要的任何时态。例如:
I don't know when she came here.
Can you tell me when he will come here?
(2) 如果主句是过去的时态,从句也应用过去时态的某一种。但若从句是表示客观事实或真理时,从句时态不受主句时态的限制,应用一般现在时。例如:
He told us why he would stay at home the next day.
The
3、 teacher explained how the earth goes around the sun.
5. 某些由连接代词或连接副词引导的宾语从句可改为含“特殊疑问词 + 动词不定式”结构的简单句。例如:
Can you tell me where I can buy this book?
→ Can you tell me where to buy this book?

语态
① 英语有两种语态:主动语态和被动语态
主动语态表示主语是动作的执行者
被动语态表示主语是动作的承受者
② 被动语态的构成
由“助动词 be+及物动词的过去分词”构成
助动词 be 有人称、数和时态的变化,其变化规则与 be 作为连系动词时完全一样。
③ 被动语态的用法
当我们不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者,或者只需强调动作的承受者时,用被动语态。
倒装句
由 so+助动词(be/do/will/have)情态动词+主语 意为:…也是一样
例如:
She is a studen
6、t.So am I. 她是一个学生,我也是。
She went to school just now.So did I. 她刚才去学校了,我也是
She has finished the work.So have I. 她已经完成了工作,我也完成了。
She will go to school.So will he. 她将去学校,他也是。
程度副词
程度副词:
always 总是
usually 经常
sometimes 有时
never 从不
如:
I am always/usually/sometimes/never late for school.
我总是经常/有时/从不上学迟到。
