1.Give me a book please, Jane.请拿本书给我，简。

　　这是一个祈使句。祈使句表示请求或命令。(请参见Lessons 13-14语法部分的说明。)表示客气的请求时，通常加please。

　　2.Which book? 哪一本?

　　是Which book do you want?的省略形式。下文中的This one? 是Do you want this one?的省略形式。No, not that one是No, I do not want that one的省略形式。口语中常用这样的省略句。

　　3.This one? 是这本吗?

　　相当于：Do you want this one? one是不定代词，代替 a book，以避免重复。one的复数形式是ones。one和ones前面都可用定冠词，也可有自己的定语。如：

　　4.数字1，010，1，011，1，016的英文写法

　　1，010----a thousand and ten

　　1，011----a thousand and eleven

　　1，016----a thousand and sixteen

　　语法 Grammar in use

　　1.人称代词

　　代词，顾名思义，就是用来代替名词或名词短语的词，在已经知道所指的是谁或什么的情况下使用，以免行文重复。人称代词有主格和宾格之分。在陈述句中，主格代词差不多总是位于动词之前。宾格代词可代替处于宾语位置上的名词，它们可以作直接宾语和间接宾语。

　　Give me/him/her/us/them a book.

　　给我/他/她/我们/他(她)们一本书。(宾格代词)

　　2.which引导的特殊疑问句

　　(请参见Lessons 5-6中语法部分的说明。)

　　用which +名词可询问物体(单数或复数)或物质。which总是说明一种限定的、特指的选择。如：

　　Which book/books do you prefer?

　　你喜欢哪本/哪些书?

　　Which car do you like best?

　　你最喜欢哪种汽车?

　　词汇学习 Word study

　　1.large与big (1)large仅指物理量值的大，是small的反义词。

　　large主要指体积、面积、形状、数量方面的大，修饰人时指个子大。如：

　　China is a large country.

　　中国是一个幅员辽阔的国家。

　　Look at that large woman in white.

　　瞧那个身穿白色衣服、个子高大的女人。

　　(2)big所表示的大，主要指不仅体积大而且很重。所以a large box未必big。big在修饰人时，主要指大人物，但个子未必高大。如：

　　It is a big house.

　　这是一所大房子。(此句指不仅体积大，而且给人深刻的或结实的印象。)

　　She's very big in the filmdom.

　　她在电影界中是个响当当的人物。(此句指不仅成功，且具有很大的影响力。)

　　2.small与little

　　(1)small指物理量值的小或少，是large的反义词，不带什么感情色彩。如：

　　It is a small factory.

　　这是一个小新概念。

　　I want the small one with the yellow handle.

　　我想要带新概念把手的那个小的。

　　(2)little也表示小或少，但有小而可爱的感情色彩，是big的反义词。如：

　　There is a little garden behind our house.

　　我们的屋后有个小花园。(此句表示花园虽小，但很可爱。)

　　She has the sweetest little smiles.

　　她的微笑十分甜蜜可爱。
