I feel it is pity that you didn't want to take part in the speech contest. In my view, the speech contest can benefit from you in different ways. Firstly, it makes you look for more informations about your favorite scientists on the Internet or in the library and learning more about them. Secondly, it is a challenge to prepare for a speech contest. You not only have to write a good article and also have to perform them properly．What's more, after the contest, you can find yourself with some newly good friends, or even a prize．I suggest you consider participating in the contest, that will really do good to you. If you change your mind, please let me know as sooner as possible·
