When you are reading something in English, you may oftencome acrossa new word. What's the best way to know it? You need an English-Chinese dictionary. It will tell you a lot about the word, for example, how to read the word, what it means (意思) in Chinese and how to use this word. But there are so many English words in the dictionary and how can you know where the word is? There is a way to look for it.
In the dictionary, you can first see the words beginning with the letter "A ", then B, C, D, E…… That means, if there are two words, "desk "and "hour", "desk" will be before "hour"; "story" before "Sunday"; "tomato" before "tomorrow" etc. The English-Chinese dictionary will be your good friend. I hope you will often use it in your English learning.
