Please your homework tomorrow.

Grammar
考点1 疑问词+动词不定式
一“疑问词+动词不定式”可在句中用作宾语、主语和表语。
eg:Can you tell me how to spell the word?你能告诉我怎么拼写这个单词吗?
How to go there is a question.如何去那里是个问题。
二【重点】疑问词+动词不定式"作宾语是初中阶段的重点。在"疑问词+动词不定式”结构中,只有疑问词why不能与不定式连用。有些疑问词,其后可先接名词再接动词不定式。作宾语时,此结构常用于know, learn, see, hear, ask, tell,advise, decide, explain, find out, forget, remember, think, understand, wonder 等动词或动词短语中。也可用于sure,clear等形容词之后。
eg:The teacher is telling the students what to do.
老师正告诉学生们要做什么。
Have you found out what time to start?
你査淸楚什么时间开始了吗?
I am not sure which way to take.
我不确定走哪条路。
【测一测】
—I’ll have a ten-day holiday. But I don’t know
一How about Paris?
A. what to do B. where to go C. when to go
考向三:“疑问词+动词不定式”结构可以改写为该疑问词引导的从句。
eg:We do not know what to do. = We do not know what we should do.我们不知道该做什么。
考点二must和have to
一【重点】:must的用法 must为情态动词,后接动词原形。must侧重于表示说话人的主观意愿;must not语气比较强,表“禁止,不允许”。
Must I…?的否定回答用“No, you needn’t. ”,或“No,you don’t have to. ”
【测一测】From March 23rd 2013, anyone under the age of 14 go into Disney’s US parks alone.
A. couldn’t B. mustn’t
C. needn’t D. mightn’t
【测一测2】
一Mom, must I take out the trash now?
—No, you . You may take a rest first.
A mustn’t B can’t C. shouldn’t D. don’t have to
二【重点】:have to的用法
have to"不得不",侧重于表示客观需要;第三人称单数形式为has to。
【测一测】It’s getting dark. I go home now.
A. can B. would C. have to

19. Please tell me (何时交作业).
20我正在计划怎样度过这个假期。
1. to do 2. to ask 3. to solve 4.stay 5 cross
二、6.C点拨:本题用语法判定法和语境联想法。由上文中“我们必须等到灯变绿吗?”和下文中“那是交通规则”可知,我们必须要等到灯变为绿色。 have to“不得不”,强调客观上的要求,故选C。
7.C点拨:本题用辨析法。can可以;may也许;must必须;need需要。根据句意:我们学校的学生必须知道不允许在图书馆大喊大叫。所以选择答案C
8.C点拨:本题用语法判定法和辨析法。根据 not...until“直到……才”的用法,首先排除A和B,又根据句意:“直到交通灯变成绿色你才能通过马路。”可知语气是“禁止”,故选C。
9.D点拨:本题用句意理解法。根据后面 too dangerous可知是不准坐前面。B是“不必”,相当于don' t have to mustn''t意为“禁止”,故选D。
10.A点拨:本题考查“疑问词+不定式”结构。 what to do how to do it,故A
三、11. to improve
12 to find
