Grammar in use
Must与Need
must表示“必须，应当”
You mustn’t make a noise! 你不该弄出噪音来！
Must I call the doctor 我必须请大夫吗？
need 做情态动词时，need表示“需要”、“必须”，作助动词时多用于疑问句和否定句，没有时态，人称、数格的变化，可以直接加否定形式。不能单独做谓语，后边加动词原形。
need + 动词原形 need 是情态动词
Need I make an appointment 我需要约一下时间吗？
You need not hurry. 你不必太匆忙。
need 做实义动词时，就有人称、数格及时态上的变化，疑问句中也需用助动词do；
need + to + 动词原形 need 是实义动词
在肯定句中，need不可以象 I can go home.中的can的用法一样在肯定句中直接做情态动词，而是做实义动词。
I need to go home.
在肯定句中，need后只跟动词不定式，不跟动词原形。而在否定句和疑问句中，情况就不是这样了。
I needn't study. （need 情态动词）
I don't need to study. （need 实义动词）
Need you study （need 情态动词）
Do you need to study （need 实义动词）
