Dictionaries are of great importance and use in study, no matter in Chinese learning or English learning. They are another teachers of us when we need some help. When we meet new words, the dictionaryat hand is the best choice to get help. The dictionary will tell us how the word pronounces, what it means and how to compose a phrase or sentence. And it will tell us the words with similar meanings or pronunciations. With the development of dictionaries, there are various types of dictionaries. Electronic dictionaries are the new ones. They are very popular among students,because they are easy to use and carry. But, we should use dictionaries properly and we can't depend on them all the time. Sometimes we needn't look up every new word in dictionary, but to guess its meaning according to the context. Besides, some small dictionaries or electronic dictionaries are not so comprehensive, the authoritative ones are the best.

不管是学习汉语还是学习英语，字典对学习很重要也很有用。当我们需要帮助的时候，字典是我们的另外一个老师。当我们遇到生词的时候，手边的字典是获得帮助的最佳选择。字典会告诉我们词怎么发音，什么意思以及怎样组成词组或造句。而且它会告诉我们它们的近义词或者近音词。随着字典的发展，字典的种类多种多样。它们在学生当中很受欢迎，因为他们使用方便，便于携带。但是，我们应该合理利用字典，不能总是依赖字典。有时候我们不需要每个生词都要查字典，而只需要根据上下文猜它的意思。除此之外，一些小字典或者电子词典不是很全面，权威的才是最好的。
