七. 介词( 注意总结书上词组)
八.副词:用法及形容词变副词的变化
u 副词可以修饰形容词,动词,副词或整个句子。如:
The book is very good.
He runs fast.
She came here quite early.
Certainly I will go with you.
u 变化:
1. 直接在形容词后加-ly,
careful-carefully, slow-slowly,
2. 以辅音字母加y结尾的形容词,把y变I, 加-ly,
happy-happily, lucky-luckily
3. 有些词形容词和副词的形式相同,不需要做任何变化
fast, hard, late
4. 有些词加上-ly后意思与原词相差很远:
neary-nearly, high-highly, late-lately,
九. 情态动词的使用:can, must, may, might, need,
1.情态动词can(能够), must(必须), may(可以)
结构:主语+can/must/may+动词原型
He can make the tea.
Sally can air the room.
We can speak English.
★变疑问句将情态动词移到句首
Can he make the tea?
Can Sally air the room?
Can we speak English?
★变否定句在情态动词后面加not
He cannot make the tea.
Sally cannot air the room.
We cannot speak English.
★肯定回答及否定回答
Yes, he can. No, he cannot.
Yes, she can. No, she cannot.
Yes, we can. No, we cannot.
★特殊疑问句:
What can you do?
(必背)
注意:情态动词的句子没有第三人称单数的变化,不要在情态动词或动词后面加S。
2.Must/have to的区别
must 表示必须,是主观上觉得应该做,have to是不得不,是由于客观条件逼迫的必要要做
must 只能用在表示现在和将来的句子里,而have to do可以用在任何时态
3.must, may, might表示猜测:
u must do 表示对现在事实的猜测
u must have done表示对过去事实的猜测
u must have been doing 表示对过去正在进行的事实的猜测
u may/might do, may/might have done表示没有任何事实依据的猜测,might的可能性更小。
u can’t/couldn’t 表示不可能
4.need 用法:
u 表示“需要”时为实意动词,后面可以加名词,也可以加不定式:
I need a pen. Do you need any beer? No, I don’t.
I need to have a rest.
u Need doing=need to be done,表示被动
The flowers need watering.
u Need在否定时做情态动词使用
You needn’t go so early. =You don’t need to go so early.
Must I clean the desk right now? No, you needn’t.

几种常见时态的相互转换
英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式:
一、 一般过去时与现在完成时的转换
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能。但是,可用别的表达方式:①瞬间动词用于“一段时间 + ago”的一般过去时的句型中;②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用;③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从……以来有……时间”的意思,主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看:
A. He joined the League two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
二、 一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作), at school(上学、上课)等。此短语可与进行时态转换。请看:
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
三、 现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如:I am coming, Mum! 意为“我就来,妈妈!”请看:
The train is leaving soon.
The train will leave soon.
四、“be going to+动词原形”与“will(shall)+动词原形”结构的转换
“be going to+动词原形”、表示打算、计划要做的事;将来时“will(shall)+动词原形”结构在书面语中,当主语为第一人称时,常用助动词shall。在口语中,所有人称都可以用will。请看:
We are going to visit the Great Wall next Sunday.
We shall visit the Great Wall next Sunday.
