一般情况，一般将来时的对划线部分有三种情况。
1、问人。Who 例如：I am going to school. Tom will go to school. Are you going to school? Will Tom go to school? Who’s going to school? Who will go to school?
2、问干什么。What ? do.例如： My father is going to watch a race with me this afternoon. Is your father going to watch a race with you this afternoon.？
What is your father going to do with you this afternoon？ My father will watch a race with me this afternoon. Will your father watch a race with you this afternoon.？

3、问什么时候。When.例如：She is going to swim at nine. She will swim at nine. Is she going to swim at nine？ Will she swim at nine？
When is she going to swim？ When will she swim?
六、同义句：be going to = will (be going to 常指客观情况，will 常指主观情况) I am going to go swimming tomorrow（明天）. = I will go swimming tomorrow. 一、填空。

1．一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。一般过去时也表示过去经常或反复发生的动作。 2．Be动词在一般过去时中的变化： ⑴am 和is在一般过去时中变为was。（was not=wasn't） ⑵are在一般过去时中变为were。（were not=weren't）
⑶带有was或were的句子，其否定、疑问的变化和is, am, are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首。 3．句中没有be动词的一般过去时的句子
否定句：didn't +动词原形，如：Jim went home yesterday.
Jim didn't go home yesterday.
一般疑问句：在句首加did，句子中的动词过去式变回原形。
如：Jim went home yesterday.
Did Jim go home yesterday?
特殊疑问句：⑴疑问词+一般疑问句？如：Jim went home yesterday. Did Jim go home yesterday? What did Jim do yesterday?
动词过去式变化规则：
