1． 主语＋不及物动词
不及物动词的后面不接宾语,但很多时候,这个不及物动词有副词或别的状语修饰.有的动词如果不加状语修饰,句子的意思就可能不完整.如：
Mr． Li stayed． → Mr． Li stayed until the meeting was over．
She lived． → She lived in the country．
2． 主语 ＋ 系动词 ＋ 表语
在这类结构中,可用作表语的有分词、形容词、名词、代词、副词、介词短语等.如：
We are determined to compete for the first prize in the match．
She was too tired．
Mr． Li is a middle school teacher．
It’s me．
The light was out．
Your father is in his office．
3． 主语＋及物动词＋宾语
可以用作宾语的通常有名词、代词等.如：
I saw a film yesterday．
I didn’t meet him at the meeting．
4． 主语＋及物动词＋间接宾语＋直接宾语
这类结构中的间接宾语和直接宾语又统称为双宾语.常接双宾语的动词有：give,pass,send,teach,buy,bring,show等.直接宾语和间接宾语的位置通常可以互相交换.当直接宾语（指物的宾语）位于间接宾语（指人的宾语）前面时,间接宾语的前面通常有一个介词for或to.如：
Mother bought me a watch． →Mother bought a watch for me．
She showed us her new dress． →She showed her new dress to us．
5． 主语＋及物动词＋宾语＋宾补
可以用作宾补的词语有形容词、分词、副词等.如：
I heard him singing in her room．
We must keep our rivers clean．
任何句子都是在上述的这些句子的基础上变化而来的.所以,我们要注意把握这些基本的句型结构,写出完整而又符合规则的句子.
