When you read something in English, you may meet a new word. What's the best way to know it?
You may look it up in an EnglishChinese dictionary. It will tell you everything about the word:the pronunciation (发音), the part of speech (词性), the Chinese meaning and how to use this word. But how can you know where the word is in thousands of English words? How to find it in a dictionary quickly?
First, all the English words are in alphabetical order. In the dictionary you can first see the words beginning with the letter A, then B, C, D, E… That means, if(如果)there are two words "do" and "put", "do" will be certainly(肯定)before "put". Then if there are two words both beginning with the same letter, you may look at the second letter, then the third, the fourth… For example, "pat" is before "picture", and "bald" is before "balloon". Do you understand how to look up a word in a dictionary?
The dictionary will be your good friend. You can learn better with it. I hope you'll use it as often as possible in your English learning.
