三、一般現在時的句子轉換：
（1）當句子中有be動詞或情態動詞時，則把be動詞或情態動詞(can,could等等)提到主語的前面變成疑問句;在be動詞或情態動詞後面加not變成否定句.
例：①陳述句：she is a student.
疑問句→ is she a student?
否定句→ she is not a student.
②陳述句：i can swim.
疑問句→ can you swim
否定句→ i can not swim.
（2） 當句子中即沒有be動詞，也沒有情態動詞時，則在主語前加助動詞do (you,以及複數), does（單數she,he,it）變成問句；在主語後謂語動詞前加助動詞don』t（i,you,以及複數), doesn』t（單數she,he,it）變成否定句，助動詞後的動詞要變成動詞原形。
例：①陳述句：we get up at 7:00 every morning.
疑問句→do you get up at 7:00 every morning?
否定句→we don』t get up at 7:00 every morning.
②陳述句：she has a little brother.
疑問句→ does she h**e a little brother?
否定句→ she doesn』t h**e a little brother.
