课文详注 Further notes on the text 1．Can't you come in and have tea now, Peter?彼得，你现在能进来喝茶吗？这是否定疑问句，表示邀请。请参见第77-78课_Terrible toothache语法部分。
2．Don't you remember?你不记得了吗？
这也是否定疑问句。
3．don't need to= needn't。
表示“不必”，是 must和 have to的一般现在时否定式。
4． a pleasant surprise,意想不到的好事，令人惊喜的事。
语法 Grammar in use
must, have to和 needn't
这3个词都表示必要性。在前面已对 must和 have to介绍过。
must是情态助动词，而have to是普通动词，二者在肯定句中一般可以互换，表示不可逃避的义务或责任。must更带有说话人的主观色彩，而have to则更强调客观要求和外界影响。
must一般只能表达现在的必要性，而have to则可以表达过去或将来的必要性。对比例句：
Must you go now?
