positive and negative sentense

Rules for changing between positive and negative statements:


A. Identifying the tense (找出時態) and the verb:


In the example, the verb 'go'; indicates it's a present tense


B. For a positive statement. Put the verb (go) after the subject (They)
and continue.

i. For a negative statement in present tense with the subject being 1st or 2nd person or 3rd person plural (第一/二身或眾數第三身) ,for example, 'I, We, They', put 'do not'; after the subject; and the remaining follows as given.

ii. If the subject is a 3rd person singular(單數第三身) i.e. 'He, She, It, A woman, The dog, etc.', put 'does not' after the subject, this time the verb must change to simple form, and the remaining exactly as given.
