Linguistics class

Today was the first time we use the linguistics textbook. This is the new class for me, for I learn only how to use the skills in the past. Therefore, it is the first time I learn theoretical English. It is a quite difficult lesson for me. Because I know the meaning of every word, but when it combines into a sentence, I think I can’t understand it. Then, I get lost. I begin to ask my friends which part does teacher talks about in the textbook.
After the class, I think I should spend more time on this class. Otherwise, I will fail in the end of semester. I don’t want to take the same course in the future. So I will try to do the best in the course.
