1.What's the matter?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。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：
1.there +be结构
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。
