對的，所以我們必須守時。

1)must作為情態(tài)動詞，表示“必須”、“務(wù)必”，有時還表示“一定”，起到加強語氣的作用。如：

Youmustcometomorrow.

你(們)明天必須來。

Shemusthavethisdictionary.

她一定有這本字典。2)ontime是一個固定介詞短語，表示“按時；準(zhǔn)時”。如：

Wemustgettoschoolontime.

我們必須按時到校。

Planesandtrainsdon’talwaysarriveontime.

火車、飛機并不總是準(zhǔn)點到達(dá)。3)系動詞be與形容詞或介詞短語聯(lián)用，是英語一種常見的語句結(jié)構(gòu)，表示某種狀態(tài)。如：bequiet保持安靜；bestrict要求嚴(yán)格

beontime守時；beatwork在上班

這種用法中，動詞be主要承擔(dān)著連系句子的語法功能，其后的形容詞或介詞短語則起著表意的作用。如：

youmustn’tbenoisy,children.

孩子們，你們一定不可喧鬧。

Atthistimeoftheday,childrenareatschool.一天中的這個時候，孩子們在學(xué)校上課呢。2.arrive

late

late

for

意思相近,都表示“遲到”。Don’t

arrive

/belate

for

school.上學(xué)別遲到。I

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

day.

湯姆每天必須練習(xí)彈吉它。I

5:00

last

Monday.

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’thaveto;

句子是過去時,用didn’t

have

a

uniform.尼克不必穿制服。We

have

you

have

stay

at

home

on

weekends?

周末你必須呆在家里嗎?Yes,

I

do.

/

I

don’t.

是的,我必須。不,我不必。Exercises根據(jù)漢語提示填入恰當(dāng)?shù)膯卧~。1.RoseandLisaarereadinginthe_________(教室).2.Therearelotsof_______(規(guī)則)inAlan’sschool.3.Johnoften________(打架)withhisbrotherbecauseoflittlethings.4.Thereisabigdining______(大廳)inourschool,andweeatlunchthere.5.It’sraining________(在外面).Juststayathome.classroomrulesfightshalloutside按要求改寫句子，每空一詞。1.Paulhastoeatoutside.(改為一般疑問句)_____Paul________eatoutside?2.Theycanwearhatsinthehall.(改為一般疑問句)_____they_____hatsinthehall?3.Thestudentshavetowearsportsshoes
