Which of the following statements is true according to the speaker?

Today I’d like to talk to you about dictionaries because most of you have them, but don’t use them very often. Whenever I ask people what a dictionary is for, they almost always say that it’s to find the meaning of a word. Well, but that’s really only a small part of the answer. Sure, a dictionary will tell you the meaning of a word, and it will also give you examples to show you how the word is used in a sentence, but it will also tell you how to pronounce a word you’ve already known the meaning of. And this is very important, because if you can’t say a word correctly, then no one will understand you. Of course, learning the pronunciation symbols your dictionary uses will take a little time, but it’s worth it, believe me.
    Now think about when you’re writing something, are you always sure of the spelling of every word? If not, what do you do? Do you just write it the way you think it’s spelled and hope it’s correct? Or, do you wait around for someone to tell you the spelling, or do you look for another word to use instead? What you should do is to open your dictionary and check to see that if your spelling is correct. If it isn’t, think of another way the word might be spelled and check that out. Through guessing and checking you’re sure to find the right spelling.
    Another thing to help you when you’re writing is the dictionary will tell you where each syllable of a word begins and ends. This is important information, because when you write in English, when you came to the end of the line on a piece of paper you cannot separate words where you want to, but only between syllables. So you can use your dictionary to find out if you’re separating the word in the right place.
