Homework of Intro to Linguistic 001

I am recently taking Linguistic 001 which is hard for an international student like me. It is about phonetic. If you took or majored in Linguistic, I desire your help. I put everything you might need to know in the files section down below, including homework, it has two parts A & B. The first and second files are the homework, please finish them in the docx. The third one is a rough PPT about what we learned in week two. The forth and fifth flies can help you to understand what is the homework about. Lastly, here is the link to our book: https://drive.google.com/open?id=140QqsbUkdfdlad6vicNFdCWYoZIIlkZI . You can find what you need to know to do the homework in Chapter one and two, but you do not have to read all them. Thank you for your help!
