Task 5: Corpora.

The most important difference between the two Corpora is that in the http://corpus.byu.edu/bnc/ you write an expression as, for example, cheer up and it gives you the number of frequency in which it is used. In my case, the number is 101. After that in both corpora you have all the uses that the word has in context.
In my opinion, the second web page is more clear in order to see the collocation of the words as the colour in which the words are written and the aspect of the web page is more pleasant. Although in the other one you have the information of the number of uses.
