Positive and negative agreements: so/too, either/neither

Positive and negative agreements /əˈɡriːmənts/

Today we'll learn how to express an  agreement : positive or negative one. For this purpose we can use some forms:
1. Positive agreement. You should use this form after affirmative statements.They can be formed with  SO or too and a  positive form of the auxilary verb:

•   I like coffee. -    So do I./ I do too 
• I have seen this film. -  So has he. / He has too
• Nick can sing well.- So can Ann./ Ann can too

2. Negative agreement should be used after negative statements and can be formed with the words either or neither: either is used after a negative form of the auxilary verb and neither is used before a positive one.

• He wasn't late yesterday. - Neither was I./  I wasn't either .
• Eugene can't play chess. - Neither can Sam./ Sam can't either.

Note:
neither can be pronounced in two ways  : /ˈnaɪðə(r)/ or /ˈniːðə(r)/
