　　课文详注 Further notes on the text
　　1．What's thematter？怎么啦？
　　相当于 What's wrong?或 Tell me what's wrong。这个句型通常用来询问发生了什么事。假如要特别提及某人，可以在后面加上介词with，如：
　　What's the matter with you?
　　你怎么啦?
　　What's the matter with Claire?
　　克莱尔怎么啦?
　　2．Mum，儿语中小孩子对母亲的称呼。
　　与此相似，dad是对父亲的儿语称呼。
　　3．There's = There is。
　　它表示“有”、“存在”，为 there + be结构的一般现在时缩略形式。
　　4．Two ice creams please．请拿两份冰淇淋。
　　相当于 Give us two ice creams，please。请参见 Lessons 3～4课文注释。ice cream是物质名词。物质名词前加不定冠词 a或基数词表示一种、一份、一客、一类、一阵等。
　　语法 Grammar in use
　　1．there +be结构（1）
　　在说明或询问人、物等的存在时即可使用there +be结构。说There's an ice cream man比说An ice cream man is there更合乎习惯，也更为自然。there +be结构可将重要的新信息置于句末，以示强调。此结构中的实际主语是be后面的名词。因此，假如该名词是单数就用is，如是复数则为are。
　　2．人称代词与be
　　英文中系动词be(是)必须根据不同的人称代词作相应的变化。请参见Lessons15～16语法部分中有关be的一般现在时形式的内容，包括某些缩略形式，如：they are not =they aren't =they're not，we are not = we aren't =we're not。
