2、have to go to school at weekends. _自主探究，请带着下面这些问题阅读教材。1“疑问词不定式”结构在句中可作哪些成分？2amazing与amazed有何区别？教材导读1millie has decided what to read米莉已经决定读什么了。探究点：“疑问词不定式”的结构可用作_、_和_。指点迷津 “疑问词不定式”结构的用法：(1)该结构的句法功能：“wh-词不定式”主要用作宾语。we must think what to do我们必须考虑怎么办。i can't decide whom to invite.我不能决定该邀请谁。除用作宾语外，还可

3、用作主语、表语等。when to leave has not been decided.何时离开还没有决定。the question is how to find him.问题是如何找到他。(2) why用于该结构的注意点：原则上说，why后不接不定式，不过若不定式不带to，则可用why。why not go there at once?为什么不马上去那儿呢？why argue with her?为什么要跟她争论呢？注意这类结构通常只用于谈论现在和将来，不用于谈论过去。你昨天为什么不打扫房间？误：why not clean the room yesterday?正：why didn't

4、 you clean the room yesterday?(3) how用于该结构的注意点：有些动词后接“how不定式”作宾语时，how可以省略：did you learn (how) to drive a car?你学过开车吗？但是，有些动词后面接“疑问词how不定式”作宾语时，尽管其中的how在汉语中无需译出，但不能将how省略。he knows how to play the piano.他会弹钢琴。he showed her how to swim.他教她游泳。(4)“疑问词十不定式”结构可以和复合句转换。he asked where he would go shopping aft

5、er supper.he asked where to go shopping after supper.他问他晚饭后会去哪儿购物。同义句转换the teacher asked us how we could help him.the teacher asked us_ _ _ him.2wow，that's amazing!哇，那太棒了！探究点：表示“感到惊讶的”用单词 。指点迷津(1) amazing令人惊讶的，指物，为动词amaze的现在分词。amazing news令人感到惊讶的消息(2) amazed感到惊讶的，指人，为动词amaze的过去式和过去分词。he is amaze

6、d at the amazing news.他对这个惊人的消息感到惊讶。be amazed at/by（对）大为惊讶的i was amazed at her knowledge of english literature.她对英国文学之了解让我很惊奇。小试身手单项选择( )we were all_ at the_ result.a. amazing; amazing b. amazing; amazedc. amazed; amazed d. amazed; amazing3we do not have to go to school at weekends.在周末我们不必上学。探究点：表示客

7、观需要的“必须”用_.指点迷津表示客观需要的“必须”用have to。have to和must的区别如下：(1)两词都是“必须”的意思，have to表示客观的需要，must表示说话人主观上的看法，即主观上的必要。my brother was very ill, so i had to call the doctor in the middle of the night.我弟弟病得很厉害，我只得半夜里把医生请来。（客观上需要做这件事）he said that they must work hard.他说他们必须努力工作。（主观上要做这件事）(2) have to有人称、数和时态的变化，而mus

8、t只有一种形式。但must可用于间接引语中表示过去的必要或义务。he had to look after his sister yesterday.昨天他不得不照顾他的妹妹。(3)在否定结构中don't have to表示“不必”，mustn't表示“禁止”。you don't have to tell him about it你不一定要把此事告诉他。you mustn't tell him about it你一定不要把这件事告诉他。( ) you_ smoke in public.a. mustn't b. needn't c. wouldn&
