“肯定句（英語）怎樣寫”

一.肯定句變成否定句
如果句中有be動詞is,am,are 或情態(tài)動詞must,can等,在其后面直接加not,
she is your mother. she isn't your mother

2.如果沒有be動詞或情態(tài)動詞,加don't,does't或did't
she likes playing football. she doesn't like playing football.

二.肯定句變成疑問句
變成一般疑問句

如果有be或情態(tài)動詞動詞就把他們提前,
she is your mother. Is she your mother?

2.如果沒有就在前面加do的某種形式,第三人稱用does,過去時用did
she likes playing football. Does she like playing football?

變成特殊疑問句,
要具體分析,看是對什么進(jìn)行提問,簡單來說,
1.對人提問用who, she is your sister.Who is your sister?
2.對事物用what, The book is on the desk. what it is on the desk?
3對時間用when, She will come back tomorrow. When she will come back?
4.對頻率用how often等等 I play football everyday. How often does you play footall?
