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.
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 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 student.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:
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。
