We?can?eat?in?the?cafeteria,?but?we?can't?eat?in?the?classroom.?我們可以在自助餐廳吃東西,但是我們不能在教室吃東西。 3.?Can?y

5、ou?wear?hats?in?school??你們在學??梢源髅弊訂幔縔es,?we?can.?/?No,?we?can't.?是的,我們可以。/不,我們不可以。 4.?Do?you?have?to?wear?a?uniform?at?school??你們在學校不得不穿校服嗎?Yes,?we?do.?/?No,?we?don't.?是的,我們要穿。/不,我們不穿。 5.?What?else?do?you?have?to?do??你還有別的不得不做嗎?We?have?to?clean?the?classrooms.? 我們不得不打掃教室。 ?重、難點解析: 1.?情態(tài)動詞have

6、?to?的用法,意思是"必須、不得不",它側(cè)重于客觀上的必要和外界的權(quán)威。(1)結(jié)構(gòu):主語+have?to+動詞原形+其他 (一般現(xiàn)在時,主語是第三人稱單數(shù)時,用has?to;句子是過去時,用had?to.)如: We?have?to?wear?sneakers?for?gym?class.?在體育課上,我們必須穿運動鞋。 Tom?has?to?practice?the?guitar?every?day.?湯姆每天必須練習彈吉它。 I?had?to?get?up?at?5:00?am?last?Monday.?上周一,我不得不早上5點起床。 (2)否定形式:主語+don't?

7、have?to+動詞原形+其他 (一般現(xiàn)在時,主語是第三人稱單數(shù)時,用doesn't?have?to.?句子是過去時,用didn't?have?to) 如:Nick?doesn't?have?to?wear?a?uniform.?尼克不必穿制服。 We?didn't?have?to?do?our?homework?at?once.?我們不必馬上完成作業(yè)。 (3)疑問句:Do?(Does或Did)+主語+have?to?+動詞原形+其他 如:Do?you?have?to?stay?at?home?on?weekends??周末你必須呆在家里嗎?Yes,?I?do.?/?No,?I?do

8、n't.? 是的,我必須。不,我不必。Did?he?have?to?go?to?bed?by?11:00?last?night??昨晚,他不得不11點前上床睡覺嗎?? 2.?情態(tài)動詞can的用法 (1)表示能力,"會""能"(在第一冊中已經(jīng)學習這種用法) Can?you?play?the?guitar??你會彈吉它嗎?Judy?can?speak?a?little?Chinese.?朱蒂會說一點中文。I?can?dance?and?sing.?我能唱歌又能跳舞。 (2)表示允許、許可,"可以"、"能"(在這一課中新學的詞義) Can?the?students?run?in?th

9、e?hallways??學生們可以在走廊上跑嗎?We?can?eat?outside.?我們可以在外面吃東西。Can?I?come?in??我能進來嗎? 注意?同樣是情態(tài)動詞,can?和have?to?的用法是有區(qū)別的,和大部分情態(tài)動詞一樣,can在否定句中,直接在can后加上not,在疑問句中,把can放到主語前面,并且沒有人稱和數(shù)的變化。 ?3.?hear,listen和sound都有"聽"的意思,但三者是有區(qū)別的。 (1)hear"聽說",側(cè)重于"聽"的內(nèi)容 I'm?sorry?to?hear?that?you?are?ill.?聽說你生病了,我很難過。 I?never?h

10、eard?such?an?interesting?story.?我從來沒聽過這么有趣的一個故事。 (2)listen"聽"側(cè)重于"聽"這一動作。Listen?to?me?carefully.?認真聽我說。 The?children?like?to?listen?to?music.?孩子們喜歡聽音樂。 (3)sound"聽起來",它是系動詞,后面接形容詞等。That?sounds?great.?那聽起來真不錯。 It?sounds?like?fun.?聽起來挺有趣。 4.?be?in?bed?"在床上、臥床"in?和bed之間不能用冠詞,bed也不用復數(shù)。 He?is?in?

11、bed?for?10?years.?他臥床10年了。Dave?has?to?be?in?bed?early?every?night.大衛(wèi)每晚必須很早睡覺。 5.?arrive?late?for?與be?late?for?意思相近,"遲到"Don't?arrive?(be)late?for?school.?上學別遲到。I?arrived?(was)late?for?the?meeting?yesterday.?我昨天開會遲到了。 6.?No?talking?!?"禁止交談!"no后面加上名詞或動名詞(doing)也表示不要做某事。與don't?+do的用法相似。No?wet?umbrel

12、las!?/?Don't?put?wet?umbrellas?here!?禁止放濕雨傘! No?food!?Don't?eat?food?here!?禁止吃食物!No?smoking!?Don't?smoke?here!?禁止吸煙! 語法(祈使句) 祈使句是用來表示請求、命令、叮囑、號召或者勸告等的句子,這類句子的主語常是第二人稱you,也就是聽話者,因而you常省去了。祈使句的開頭是動詞原形。 如:Look?out!?小心!Wait?here?for?me!?在這等我! Be?sure?to?come?here?on?time!?務(wù)必準時來到這里! 祈使句的否定形式多以do?

13、not(常縮寫成don't)開頭,再加上動詞原形。 Don't?arrive?late?for?school.?上學別遲到。 Don't?fight!?別打架! Don't?look?out?of?the?window.?不要向窗外看。 Unit 12 Don’t eat in class. ( The 1st period section A: 1a, 1b, 1c, 2a, 2b, 2c Teaching aims: Knowledge aims: To master the following new words and sentences in?class:?
