Grammar Rules
shuld表示建议或劝告，意为“应当”，可用于肯定句、否定句和疑问句。否定形式shuld nt (shuldn't)表示“不应”的意思。例如:Yu shuld listen t the dctr's advice.你应当听从医生的建议。Yu shuldn't eat t much junk fd if yu want t stay healthy. 如果你想保持健康，就不应该吃太多垃圾食品。
must意为“必须”，可用于肯定句、否定句和疑问句。否定形式must nt(mustn't)表示“不应该”或“禁止”的意思。例如:She must learn t manage her time better.她必须学会更好地管理自己的时间。Yu mustn't talk ludly in the library.图书馆内禁止大声喧哗。
注意：must开头的一般疑问句，肯定回答用must， 否定 回答用needn’t 或dn’t have t
— Must I cme befre 6:30 tmrrw? 明天我必须在六点半之 前来吗?— Yes, yu must.是的，你必须在那之前到。(表示一定要)— N, yu needn't.不，你不必在那之前来。(表示没必要， 相当于Yu dn't have t.)
can意为“请求允许”和“给予许可”，可用于肯定句、否定句和疑问句。否定形式cannt (can't)表示“不能，不可以”，语气弱于must nt(mustn't)。例如:When yu get t knw each ther better r when they ask yut, yu can just use their first names.当你们更加熟悉或他们请你(这样做)时，你就可以只称呼他们的名字了。Yu can't put the milk in first.你不能先倒入牛奶。(没有禁止的含义)Can I have a lk at yur phts?我可以看一下你的照片吗?
can开头的一般疑问句，肯定回答用can， 否定回答用can’t
— Can we g hme nw, please? 请问我们现在能回家吗?— Yes, yu can.可以。(表示允许)— N, yu can't.不行。(表示不允许)
need作情态动词时意为“需要”，可用于肯定句、否定句和疑问句。否定形式need nt (needn't)比较常用，表示“不需要”或“不必要” 例如:If she wants anything, she need nly ask.如果她要什么，说一下就行了。Yu needn't wait.你不必等待。请注意: need也可以作行为动词，意思也是“需要”，常用于need t d sth结构。例如:I need t clean the huse.我需要把房子打扫一下。Yu dn't need t leave nw. It's still early.你没必要现在就走， 时间还早。
以情态动词need开头的一般疑问句，肯定回答用must， 否定回答用needn’t
— Need I reprt it t the plice?我要向警方报告这件事吗?— Yes, yu must. 是的，你必须报告。(表示必须做)— N, yu needn't.不，没必要。(表示没必要)
have t和must都表示“必须”，但must侧重于说话者的主观看法，认为有必要或有义务去做某事;have t侧重于客观需要，含有“不得不，被迫”之意。 例如:All passengers must wear seat belts.所有乘客都要系安全带。My bike was brken yesterday, s I had t walk t schl.昨天我的自行车坏了，所以我只能走路去学校。
用于否定句时，must的否定式must nt (mustn't)表示“一定不要，不允许”;而have t的否定式d nt (dn't) have t表示“不必”(= needn't)。请比较:Yu mustn't tell him abut it. 你绝对不要告诉他这件事。(可能是秘密)Yu dn't have t tell him abut it.你不必告诉他这件事。(他可能知道了或者没有必要让他知道)
had better表示劝告或建议，意为“最好……” 例如:Yu'd better get sme sleep.你最好睡一会儿。had better一般不用于疑问句中，但可用于否定句中，其否定形式为had better nt 。例如:Yu'd better nt waste any mre f yur time. 你最好别再浪费你的时间了。
