定冠词THE!分不清泛指类特指专指的特点啊麻烦细讲Knowledge is power.为什么没有THE,是因为类指还是泛指的事物?Tom owms a larger colletion of ()books than any other student in our class.为什么不用THE The diet is measured in(为什么不用THE)calories,while the food is sold by (A) pound.后者属于固定搭配?售为一磅的意思?If you buy more than ten ,they will knock 20 pence off THE price.为什么要用THE Amy is always shy in (无THE) public and she never dares to make aspeech to THE public.我的答案正是反的!为什么前面无后有?还有.定语从句的中心语通常是THE 什么什么,此处算什么指?为什么

如果是只想做题能对,那就看看吧～
1在专有名词时要加the
2前面有介词in on 之类的有可能加the
3句子中的名词有修饰（多是定语从)或是特别提出
你的问题ms是看的太少了～背的太少了很多是固定搭配

Tom owms a larger colletion of ()books than any other student in our class.
介词后不加the
The diet is measured in calories,while the food is sold by (A) pound.
以卡路里计算，仅仅作为一个单位，没有特指
以磅售出，也是。
If you buy more than ten ,they will knock 20 pence off THE price.
在这个价格上打折扣，是特指
Amy is always shy in (无THE) public and she never dares to make aspeech to THE public.
in public/in public places都不用the，
译为在公共场合
the public指的是公众，是个群体
