Assignment 4: Comment on the corpus-based reference tools.

Even we know the explanation of words, but we always don't know how to use it appropriately.

If we use the dictionary to search for words, we can get many explanations but no idea of how often it be used or what opportunity you can use it.

On the other hand, some words are used to get together with other words, it is called collocation. We often strange to use they.

Last two classes, we learned the way about how to solve this problem, the way is using corpus-based reference tools.

By using corpus-based reference tools, we can find a lot of sentence with the word, and we can follow the track about how to use the word, how frequently it be used, and its front and behind always connect to which word.

It is useful for us to know more about the word.

But the weakness is, sometimes a word have been using in a wrong place, day by day, it become a new language. for example, long time no see.

But I think if we use it, we can become more nature in english.
