Long vowels.

          In this chapter I learnt that in English we can find five long vowels that tend to be longer than the short ones. Also, there was a way that can help us to identify a long vowel. For example: A long vowel has a mark made with two dots (a :). Besides, I could notice that the five long vowels are different from the six short vowels not only in length, but also in quality because the position of the tongue or the lips can change. About the use of the marks to identify the long vowels it is not necessary to keep them because they only have the role to help learner to remember the length difference because there is no presence or absence of stress in this sounds. However, thanks to the symbols we can be able to recognize the difference between long and short vowels even if we omitted the length mark.
