“疑问词+动词不定式”的用法
We can use a questin wrd with a t-infinitive after a verb.我们可以在动词后面加上“疑问词+动词不定式”。
Millie has decided what t read. Daniel did nt say wh t talk t abut this bk.
（1）: V. + wh- + t d在动词后做宾语，表示动作的“内容”
All questin wrds can be used in this way, except why.所有疑问词都可以这样使用，除了why。
We can use a verb + bject befre a questin wrd with a t-infinitive.
我们可以用"疑问词+ 动词不定式"结构作动词的宾语。疑问词包括疑问代词wh,what,which及疑问副词when,hw,where等。常和"疑问词+动词不定式"结构连用的动词和动词短语有:tell,shw,think, learn, knw, wnder, decide,remember, frget, understand, see,hear,ask, advise(建议), explain (解释),find ut(查明，发现)等。

1. What d yu knw abut “must”, “mustn't”, “have t” and “dn't have t”?2. Can yu knw their similarities and differences (相同点和不同点)?
must和have t的用法
（1）must是情态动词，意为“必须”，侧重于说话者的主观看法，认为有必要去做某事。must没有人称、时态和数的变化。must的否定式mustn’t意为“不准，禁止”。例如： Yu must g t the hspital tday. 今天你必须去医院。 Lk at the sign. Yu mustn’t smke here. 看这个标志，这里禁止吸烟。
（2）have t意为“必须，不得不”，后接动词原形，表示客观上的必须。have t的否定式dn’t have t意为“不必，不需要”，相当于needn’t。例如： The last bus has gne. We’ll have t walk hme. 最后一班车已经开走了。我们不得不走路回家。 We dn’t have t get up early tmrrw mrning. 明天早上我们不必早起。
【拓展】回答以must引导的一般疑问句时，若是否定答复，不可以用mustn’t，而需要用needn’t或dn’t have t。例如： —Must I water the flwers? 我今天必须给花儿浇水吗？ —Yes, yu must./ N, yu needn’t. 是的，你必须。/不，你不必。
Tip:Have t has different frms. has t had t will have t have/has gt t
Tip:must nt=mustn't d nt have t=dn't have t
