一般过去时 六年级英语知识点
一般过去时是表示过去某个时间发生的动作或存在的状态的时态。例如，昨天她吃了三个苹果，我昨天6:30起床，我父亲上周很忙。它也可以表示过去经常或过去反复发生的动作，常与often、always等频率副词连用。例如，年轻的时候，他每天总是起得很早。
谓语形式是动词的过去式。例如，两年前她是一个学生，这件事情已经过去了，所以be动词is要用过去式was。另外，两年前他们/她们是学生，安昨晚洗了她的衣服，我及时地完成了作业，这些动词都要用过去式。
句子结构包括be动词的过去式句型和动词过去式句型。在be动词的过去式句型中，肯定句的结构是主语+be动词（was，were）+其他，例如，两年前她是一个学生。否定句的结构是主语+be not（was not，were not）+其他，例如，两年前她不是一个学生。一般疑问句的结构是Be动词（Was/Were）+主语+其他？例如，两年前她是一个学生吗？肯定回答为“Yes，主语＋was／were”，否定回答为“No，主语＋___”。特殊疑问句的结构是特殊疑问词＋一般疑问句（顺序）？例如，她两年前是什么职业？
Where were you yesterday。I was at home.
In the past tense。there are three types of sentences:
affirmative。negative。___ the structure of subject + past tense
verb + other words。For example。"___ the structure of subject +
did not + base form of verb + other words。For example。"She
did not eat three ___ the structure of did + subject + base form of
verb + other words + n mark。For example。"Did she eat three
apples yesterday?"
To form the negative form。add "not" after "did" and use the
base form of the verb。For example。"___."
To form the interrogative form。use "did" before the subject
and the base form of the verb。For example。"Did she eat three
apples yesterday?"
Common ___ "yesterday," "two days ago," "long ago," "in
1989," "a moment ago," and "just now."
The past tense of "be" has two forms: "was" and "were."
"Was" is the past tense of "am" and "is," while "were" is the past
tense of "are." Regular verbs form the past tense by adding "-ed" to
the end of the base form of the verb。For example。"walk" es
"walked," "play" es "played," and "work" es "worked." Verbs that
end in a silent "e" only need to add "-d" to the end of the base form。For example。"love" es "loved," "decide" es "decided," and "live"
es "lived."
