新概念英語第一冊第19-20課課文詳注 further notes on the text
1．what's the matter？怎么啦？
相當(dāng)于 what's wrong？或 tell me what's wrong。這個句型通常用來詢問發(fā)生了什么事。假如要特別提及某人，可以在后面加上介詞with，如：
what's the matter with you? 你怎么啦？
what's the matter with claire? 克萊爾怎么啦？
2．mum，兒語中小孩子對母親的稱呼。
與此相似，dad是對父親的兒語稱呼。
3．there's = there is。
它表示“有”、“存在”，為 there + be結(jié)構(gòu)的一般現(xiàn)在時縮略形式。
4．two ice creams please．請拿兩份冰淇淋。
相當(dāng)于 give us two ice creams，please。請參見 lessons 3～4課文注釋。ice cream是物質(zhì)名詞。物質(zhì)名詞前加不定冠詞 a或基數(shù)詞表示一種、一份、一客、一類、一陣等。

1．there +be結(jié)構(gòu)（1）
在說明或詢問人、物等的存在時即可使用there +be結(jié)構(gòu)。說there's an ice cream man比說an ice cream man is there更合乎習(xí)慣，也更為自然。there +be結(jié)構(gòu)可將重要的新信息置于句末，以示強(qiáng)調(diào)。此結(jié)構(gòu)中的實際主語是be后面的名詞。因此，假如該名詞是單數(shù)就用is，如是復(fù)數(shù)則為are。
2．人稱代詞與be
英文中系動詞be（是）必須根據(jù)不同的人稱代詞作相應(yīng)的變化。請參見lessons15～16語法部分中有關(guān)be的一般現(xiàn)在時形式的內(nèi)容，包括某些縮略形式，如：they are not =they aren't =they're not，we are not = we aren't =we're not。
