The man who has never been to the Great Wall is not a real man. Tomorrow is Tuesday.三、一般现在时的句子转换：（1）当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句. 例：陈述句：She is a student.疑问句 Is she a student?否定句 She is not a student.陈述句：I can swim.疑问句 Can you swim否定句 I can not swim.（2） 当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does（单数she,he,it）变成问句；在主语后谓语动词前加助动词dont（I,you,以及复数), doesnt（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。例：陈述句：We get up at 7:00 every morning.疑问句Do you get up at 7:00 every morning?否定句We dont get up at 7:00 every morning.陈述句：She has a little brother. 疑问句 Does she have a little brother?否定句 She doesnt have a little brother.（一）用动词的适当形式填空 1.
