1.一般过去时的肯定句变否定句
① 当句中含有情态动词could、would、should 等时,可直接在它们后面加not 构成否定句。
● Hecouldhelp you with Chinese.
他可以帮你学习中文。
→Hecould not/couldn'thelp you with Chinese.
他不能帮你学习中文。
② 当句中含有be动词was、were时,可直接在它们后面加not构成否定句。

上周五她上学迟到了。
→Shewas not/wasn'tlate for school last Friday.
上周五她上学没有迟到。
③ 当句中谓语不包含情态动词、且是除be动词(was,were)以外的动词时,在该动词前面加上did not/didn't,且动词还原为原形构成否定句。
● My fatherwentto work by subway yesterday.
我父亲昨天坐地铁去上班了。
→My fatherdid not/didn'tgo to work by subway yesterday.

2.一般过去时的陈述句变一般疑问句
① 移动词语的位置。将be动词(was,were)或情态动词(could,would,should..…)移到句首,首字母大写。
● Hecouldplay the violin when he was five.
他五岁时就会拉小提琴。
→Couldhe play the violin when he was five?

② 添加助动词did。当谓语中不含情态动词、且是除be 动词(was,were)以外的实义动词时,在主语前加Did,动词还原为原形。
● Marytooka lot of photos just now.

② 特殊疑问句的句式结构为:特殊疑问词+情态动词/be动词(was,were)+主语+其他?/特殊疑词+助动词+主语+动词原形+其他?
● Whatdidyoudowith your classmate in the par last weekend?
你和你的同学上周末在公园做什么了?

How interesting!

【句式结构】
