课文详注 Further notes on the text
1.Not very. 不太重。
是It is not very heavy的省略形式。口语中回答问题时，常把主语、动词和宾语都省略，只剩一个副词、一个副词词组或一个动词不定式短语等。
2.Put it on this chair. 把它放在这把椅子上。
it指bag。在没有扶手的椅子上用on，在有扶手的椅子上用in。如：
sit on a chair 坐在椅子上
sit in an armchair 坐在扶手椅里
3.cheese, bread, soap, chocolate, milk, sugar, coffee, tea, tobacco
这些词都是不可数名词。不可数名词前面不能加a或an，也没有复数形式。如果想表示“一些”之意，可用some，any等词。some用于肯定句，any用于否定句和疑问句。(可参见Lessons 27～28语法部分。)
如果要表示“一块”、“一张”、“一条”等，需加如a piece of这表示数量的短语。本课表示数量的短语还有：
a loaf of 一个
a bar of 一条
a bottle of 一瓶
a pound of 一磅
half a pound of 半磅
a quarter of 四分之一
a tin of 一听
4.a loaf of bread，一个面包。
指西餐中切成片吃的整个面包。
5.a bar of chocolate，一块巧克力。
指一长条巧克力糖。这种形状的巧克力有时也可称为一块巧克力。
there+be结构(3)
当there+be后跟单数名词或不可数名词时，动词be的一般现在时形式为is;当后面跟复数名词时，动词用are。如果后跟几个并列名词，而第一个名词是单数，动词仍用is。there+be后面的名词是句子的主语。如：
There is a hammer on the bookcase. 书箱上有个鎯头。(单数名词)
There is some tea in the cup. 杯子里有些茶水。(不可数名词)
There are three bottles of milk on the table. 桌子上有3瓶牛奶。(不可数名词，用复数量词修饰)
There is a pen, two books and a knife on the desk. 课桌上有一枝钢笔、两本书和一把小刀。(第一个并列名词是单数)
