Unit 1 Life On Mars教案
--- here pay more attention to “might” . might is very formal and it’s very polite but rarely used.
(注意：‘might’ 的用法既正式又禮貌， 但是實(shí)際生活中很少使用。)
eg: might i use your computer , mr. wu?
※ they all express permission.（他們都用于表示請(qǐng)求和允許。）
t: ok. let’s do some exercises. (ppt)
t: let’s check the answers.
1 dad, could i take your c amera?
yes, you can . ( it’s formal. )
2 may i borrow this helmet, madam?
no, you may not . ( it’s formal and polite.)
3 can i borrow your boots, mike?
yes, you can. ( it’s informal.)
t: can you give me the answers to these questions about ‘can, could, may , might’ ? (ppt)
1 can / could you go to the zoo tomorrow?
---- we can answer : --yes, you can . or no, you cannot/ can’t.
2 may/ might i use your computer , mr wu?
---- we can answer : --yes, you may. or no, you may not/ can’t .
t: here ‘could , might’ do not mean ‘the past tense’, but mean ‘more polite’.
(這兒的“could , might “ 不是表示過(guò)去時(shí)，而是表示更委婉的語(yǔ)氣。)
t: now please write sentences to ask for permission in the following situations. (ppt)
look at the 1st situation
if you are on a bus and the person in front of you has the window open and it starts to rain and you’re getting wet. how do you ask him for permission?
--- we can ask : may i close the window? because it’s formal and polite to use ‘may’ when we ask a stranger on the bus for permission.
t: look at the2nd situation
i f your cousin is watching a boring programme on tv. what do you say to ask her to change the channel.
t: we can say: ----can i change the channel? because it’s informal to use ‘can’ to ask friends for permission.
t: look at the 3rd situation
if your uncle and aunt have invited you t o join them in a walk in the park and you want to take your dog with you.///
what do you say then?
-- that’s right . we can say : ‘could i bring my dog?’ because it’s formal to use ‘could’to ask adults for permission.
step 3 the object clauses introduce d by ‘that’
t: look at grammar b .let’s learn ‘that ‘ clause (下面我們來(lái)學(xué)習(xí)that 引導(dǎo)的賓語(yǔ)從句。) (ppt)
