4) wish, wonder, think, hope 等用过去时，作试探性的'询问、请求、建议等。 I thought you might have some. 我以为你想要一些。

一、序数词——由基数词转变而来，表示“这是第几个”

1.口诀巧记基数词变序数词：“一、二、三，要全变;其余都加th;th里有例外;八去“t”;九去“e”;“ve”要用“f”替，见“y”变成“i”和“e”，词尾加上“th”;若是遇到几十几，只变个位就可以。”第一、第二、第三分别：first，second，third，eight—eighth nine—ninth，five—fifth，twelve—twelfth，twenty—twentieth，forty—fortieth，twenty-five—twenty-fifth。

2.序数词有时用缩写形式：

阿拉伯数字+序数词末尾两个字母(只有1st，2nd;3rd为特殊形式，其他都是th)

二、序数词的基本用法

1.序数词在句子中时，前面一般要加定冠词：

如：I like the second dog.

2.有时前面可以加一个不定冠词a/an来表示“再一”， “又一”这样的意思：

We’ll have to do it a second time.

3.基数词也可以表示顺序，要将基数词放在名词之后：

the first part------part one

the third lesson------lesson three

英语句子按语法结构的分类

1.简单句(simple sentence)

简单句只有一个主语(或并列主语)和一个谓语动词(或并列谓语动词)。例如：

The whole village came out to welcome him home.

The temperature and pressure are controlled and adjusted with these switches.

2.并列句(compound sentence )

并列句是由等立连词或分号把两个或两个以上的简单句连在一起。例如：

An urgent telegram was sent to her husband and she was waiting for a reply.

You can’t count on him to help; he is such a busy man.

3. 复合句(complex sentence)

复合句，即主从复合句，是有关联词连接主句和从句构成的。例如：

Whether we go or not has not been decided.
