18、下需要说明不能接受邀请的原因以表示歉意。Can you come to my birthday partytomorrow？明天你来参加我的生日聚会，好吗？Sorry, I cant.

27、ave to 后接动词原形；have to有人称、数和时态的变化, 其第三人称单数形式为has to, 其疑问形式和形式要借助于助动词do或does来完成。例如：We have to look after our sister at home.我们不得不在家照顾我们的妹妹。Does he have to get up early tomorrowmorning?明天早上他必须早起吗？I dont have to stay at home today.今天我不必呆在家里。情态动词“have to”与其他的情态动词如“can”, “may” “must”和 “should” 不同。1) 这4个情态

28、动词没有人称的变化,而have to有, 它的第三人称单数为“has to”如：He should study hard.He has to study hard.2) 这4个情态动词在一般疑问句中将它们放在句首, 在句中直接在他们后边加not即可。我们以can为例:-Can he go with us? 他能和我们一起去吗？-He cant go with us. 他不能和我们一起去。而“have to”要加助动词do , does或did才可能完成其疑问句、句。5. must/have to(1) must 表示主观“必须”；have to表示客观客观需要，即“不得不” 。I dont l
