疑问句：Was (Were) +主语+宾语?
如： Were you ill yesterday? （你昨天病了吗？） 肯定回答： Yes, I was. (是的，我病了。) 否定句： No, I wasn't. (不，我没病。)
特殊疑问句： 特殊疑问词+was (were) +主语+宾语? 如：When were you born? 你是什么时候出生的？ （2）实义动词的一般过去时态
肯定句要使用动词的过去式，否定句和疑问句要使用助动词do和 does 的过去式 did.
肯定句为：主语+动词过去式+宾语.
如： I went home at nine o'clock yesterday.（我昨天九点钟回的家。） 否定句：主语+didn't +动词原形+宾语.
如：I didn't go home yesterday. (我昨天没回家。) 疑问句：Did +主语+动词原形+宾语?
如： Did you go home yesterday? (你昨天回家了吗？) 肯定回答： Yes, I did. (是的，我回了。) 否定回答：No, I didn't. (不，我没回家。) （3）助动词和情态动词过去式如下：
shall― should（将要）用于第一人称单数 will― would（将要）用于所有人称
can -- could（能，会） may― might（可以） must― must （必须） have to― had to（不得不）
助动词和情态动词的过去时态要使用他们的过去式，后面的动词还使用原形。 如： I had to do my homework yesterday. (昨天我不得不做作业。)
（4）一般过去时态由动词的过去式表示。大多数动词的过去式是在动词原形后加上ed构成。这类动词称为规则动词。
1） 一般情况下在词尾直接加ed。 如：play― played work― worked 2） 以e结尾的动词只加d. 如：like--- liked love― loved
3） 以辅音字母+Y结尾的动词，变Y为I，再加ed. 如：study― studied carry― carried
4） 以重读闭音节结尾的动词，如果末尾只有一个辅音字母，要双写最后这个辅音字母，再加ed. 如：stop― stopped （5）--ed的读音规则如下： 1） 在清辅音后面读[t]. 2） 在浊辅音或元音后读[d]. 3） 在[t] 和[d] 后读[id].
（6）不以ed 结尾的过去式，称为不规则动词。 一般过去时态的“三变”技巧 一变：肯定句变为否定句
【技巧1】当句中含有情态动词或助动词could，would，should等时，可直接在其后面加not构成否定句。例如：
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
【技巧2】当句中含有系动词was，were 时，可直接在其后加not构成否定句。例如：
9
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me. 【技巧3】当句中谓语是除情态动词、助动词、系动词was, were以外的动词时，在该动词之前加did not / didn't，动词还原，构成否定句。例如：
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs. 二变：陈述句变为一般疑问句
【技巧1】移动词语的位置。将was，were, could，would，should等移到句首。例如：
He could pack his things himself. → Could he pack his things himself? 【技巧2】添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时，在主语之前加did，动词还原。例如：
Mr Li looked very old. → Did Mr Li look very old? 三变：陈述句变为特殊疑问句
【技巧1】确定疑问词：人who / whom，物what，地点where，时间when / what time，原因why，频率how often，长度how long，距离how far等等。例如：
They gave the concert last night. → When did they give the concert? 【技巧2】辨认结构形式：疑问词+情态动词/助动词/ was / were / did +主语+...? 例如：
The accident happened near the station. → Where did the accident happen?
2、关于名词所有格：（仅限于小学阶段 's所有格的用法） （1）表示有生命的东西的名词末尾加's。例如： Jim's bed 吉米的床
the man's wife 那个男人的妻子 children's toys 孩子们的玩具 the fox's tail 狐狸的尾巴
（2）以-es或-s结尾的名词末尾加\。例如： the students' books 学生们的书 Teachers' Day 教师节
my boss' office 我老板的办公室 a girls' dormitory 女生宿舍
（3）表示两者共同拥有的人或物(共有)时，只需要后一个名词加's(或')即可。如果表示两者各自的所属关系(各自所有)，则每个名词词尾都加上's(或')。 例如：Joan and Jane's room(房间属二人共同所有)
Joan's and Jane's room(指Joan和Jane各自的房间) （4）'s所有格所修饰的词的省略现象 1)表示诊所、店铺或某人的家等地点名词，其名词所有格后的被修饰语常常省略。例如：
I met her at the doctor's(office).我在诊所遇见了她。 He has gone to the tailor's(shop).他到服装店去了。
She went to Mr. Black's (house)yesterday.她昨天到布莱克先生家去了。
10
2)名词所有格所修饰的词，如果前面已经提到过，往往可以省略，以免重复。例如：
Whose pen is this? It's Tom's.这是谁的钢笔？是汤姆的。
The bike is not mine, but Wang Pinpin's.这辆自行车不是我的，是王品品的。
3、them与their： them表示“他们” 是人称代词宾格，放在及物动词和介词后面做宾语。如I want to help them. 我想帮助他们。 their“他们的”是形容词性物主代词，放在名词前面。These are their books.这是他们的书。
