2、 one的省略形式。口语中常用这样的省略句。3This 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。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 use1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

5、）Shes 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。）2small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
