B 语法聚焦1: 不规则动词的过去式
eat的过去式是ate，see的过去式是saw，以上两个动词的过去式不遵守“原形 + ed”的规律。我们将这类动词统称为不规则动词。以下是部分常见的不规则动词，需要熟练掌握。
小贴士
read的原形和过去式同形但不同音。
动词原形读为/ri:d/，过去式读为/red/。
练习1 请将左侧的动词原形和右侧的过去式连线配对。
不论变形是否规则，实义动词一般过去时的基本句型结构如下：
肯定陈述句：主语 + 动词过去式 + 其他成分
否定陈述句：主语 + didn't + 动词原形 + 其他成分
一般疑问句：Did + 主语 + 动词原形 + 其他成分?
肯定/否定回答：Yes, 主语 + did./ No, 主语 + didn't.
小贴士
do的过去式是did，可作为实义动词使用，如do / did homework；做助动词时无实际含义，仅用于搭建否定句和疑问句。试分析句子：
She did her English homework. (肯定句; did是实义动词。)I did not do my homework. (否定句; did是助动词， do是实义动词。)
练习2 用动词的适当形式填空。
1 He _____________ me on my arm this morning! (hit)
2 I _____________ a tall man there one minute ago.(see)
3 They didn't _____________ home after school yesterday.(go)
4 We didn't _____________ for the milk.(pay)
5 Julie _____________ a beautiful dress to the party last Friday.(wear)
D 语法聚焦3:一般过去时的特殊疑问句
特殊疑问词不充当句子主语或不修饰主语时，后接疑问语序，也即“特殊疑问词 + 一般疑问句”。
特殊疑问词充当句子主语或修饰主语时，后接陈述语序，
即“特殊疑问词 (+名词) + 实义动词过去式 (+其他成分) + ?” 或“特殊疑问词 (+名词) + was / were + 表语 (+其他成分) + ?”
E 语法聚焦4:一般过去时特殊疑问句的回答特殊疑问句不论时态，都遵循“问什么就答什么”的原则，使用肯定陈述句回答。非正式场合中，可以只针对特殊疑问词提问内容进行回应。
小贴士(www.xing528.com)
一般过去时与一般现在时的一般疑问句和特殊疑问句基本结构相同，肯定和否定的问答结构也相同。试比较以下四组句子：
— Are you sick now?
— No, I am not.
— When does he eat? And why?
— He eats late because he is busy.
— Were you sick yesterday?
— No, I was not.
— When did he eat? And why?
— He ate late because he was busy.
