section a第一课时。

一、 课前预习。

1. 从课本中查出下列单词的中文意思并抄写5次。

belong

author

picnic

possible

hair band

classical

2. 归纳出所有你曾经学过的情态动词并写出它们的汉语意思。

如:can 能。

3. 用适当的动词及情态动词填空。

1) he can swim well, but i

2) my daughter is ill. i __take care of her.

3) you must be a writeryou?

4) your shoes are so dirtyi wash them for you?

5) _you get on well with your classmates?

6) aunt li started early. she __be in the city now.

7) –peter __h**e been hurt in the car accident.

4、学习现在完成时态。

由h**e/ has + 过去分词。

表示过去发生或已经完成的某一动作对现在造成的影响或结果。

常与already, just , yet , ever, never 连用。

h**e you finished your work yet?你完成了你的工作了吗?

yes, i h**e. i h**e just finished it. 是的。我刚刚完成了。

i h**e already finished it . 我已经完成了。

h**e you ever been to china? 你曾经去过中国吗?

no, i h**e never been there. 没有,我从来也没有去过。

①表示过去已经开始,持续到现在的动作或状态和表示过去某一时刻延续到现在(包括现在在内)的一段时间的状态连用如:(for + 时间段,since + 时间点,或过去某一动作, 以及how long )

注: 非延续性动词在现在完成时态中不能和for, since 引导的表示一段时间的状语的肯定句连用。

应转为相应的延续性动词如:buy---h**e die---be dead join --be in borrow---keep le**e---be away

i h**e bought a pen.--i h**e had a pen for 2 weeks.

the dog has died.--the dog has been dead since last week.

①h**e (has) been to + 地点去过某地已经回来。

h**e (has) gone to + 地点去了某地没有回来。

h**e been in + 地点一直呆在某地没有离开过如:

she has been to shanghai. 她去过上海。(已经回来)

she has gone to shanghai. 她去了上海。(没有回来)

she has been in shanghai for 2 days.她呆上海两天了。(没有离开过上海)

二.重点难点讲解及课堂练习。

1. belong to : 属于,是…..的组成部分,无被动语态及进行时。

eg:the backpack belongs to linda.

2. 情态动词 must, may(might), can(could) 的用法。

1) must: ①表示义务,即“必须,应该”,强调主**法。在回答must的问句时,否定式常用 need not(needn’t) 或 don’t h**e to , 而不是用 must not.

eg: -must i look after the baby? -yes, you must. 是的,你必须。

-no, you needn’t./ no, you don’t h**e to.不,你不必。

表示推测,即“一定,必定”之意,只用于肯定句中,这种推测比may(might)要肯定的多。强度是must >could> may

2) may (might):①表示“许可”或征询对方的许可,回答此意时,它的否定形式可用may not, 但在回答may问句时,多用其他形式,否定回答时多用mustn’t. eg:

--may i smoke here?

--yes, please. /no,you mustn’t

表示可能,这时might不是may的过去时,只是用might时语气比may更委婉或是现实可能性更小一些,更加不肯定。

3) can (could): 表示“能力”,can指现在,could指过去。

表示“可能性” eg:she can’t be serious about it.

表示“允许”,could比can语气更委婉。

表示惊奇,怀疑,命令,迷惑等态度,主要用于否定句,疑问句及惊叹句中,could语气比can更委婉。

自我测评:1. 用must, could, might , can’t填空。

1) –look! the man looks like our english teacher.

-- itbe her. she has gone to australia.

2) –whose pen is this? -it __be jack’s. he did his homework here just now.

3) i can’t find my english book. it __be at home for i read english at home this morning.

4) you __be tired after the hard work.

5) -is that boy wang hai? -it __be him. he is much taller.

6) the basketball __be li dong’s. he often plays basketball.

7) when you cross the street, you __be careful.

8) it’s dangerous. you __play football on the street.

三.家庭作业。

1. 根据句意填空。

1) this dictionary mustto linda.

2) our classmates will go on ain the mountain.

3) my brother doesn’t like english at all. maths is hissubject.

4) be __when you cross the street.

5) haimingwei is her f**orite

2. 单项选择。

1) it’scold in the room. you should close the window.

a. too much b. much too c. too many d. many too

2) –whose child is this? -he might behe looks like her.
