宾语
表语
1．主语＋谓语(不及物动词)
该句式常用来表示主语的动作或状态。其特点为：句子的谓语动词都能表达完整的意思，这类动词叫作不及物动词，后面可以跟副词、介词短语、状语从句等。
　厘清基本句型
2．主语＋谓语(及物动词)＋宾语
该句式的特点为：谓语动词均为实义动词，都是主语发出的动作，但不能表达完整的意思，必须跟一个宾语(宾语可以由名词、代词、动词-ing形式、动词不定式、特殊疑问词＋动词不定式、从句等来充当)，即动作的承受者，才能表达完整的意思。
3．主语＋系动词＋表语
该句式就是常说的主系表结构。此句式侧重说明主语是什么或怎么样，助动词需用系动词(主要是be动词)，表语多为形容词，也可以是名词、介词短语、动词不定式、动词-ing形式等。
4．主语＋谓语(及物动词)＋间接宾语＋直接宾语
该句式中的谓语动词必须跟两个宾语才能表达完整的意思。一个是表示人的间接宾语；一个是表示物的直接宾语。一般间接宾语在前面，直接宾语在后面。
5．主语＋谓语(及物动词)＋宾语＋宾语补足语
该句式中的谓语虽然是及物动词，但是只跟一个宾语还不能表达完整的意思，必须加上一个补充成分来说明宾语，才能使意思完整。宾语补足语用来补充说明宾语的情况，直接跟在宾语之后。
6．主语＋谓语(不及物动词)＋状语
状语修饰谓语动词或整个句子，谓语动词为不及物动词(短语)。
7．主语＋谓语(及物动词)＋宾语＋状语
状语由副词、介词短语或从句充当，修饰谓语动词的状语需是副词或介词短语。
8．存现句(there be句型及there be句型的变式句型)
there be句型有很多变式，恰当地运用there be(be可用各种时态)句型及其变式对提升写作大有帮助。
①There are abundant biological resources and energy resources in the ocean．
②There is a famous saying that“good habits lead to good endings”，which shows the importance of habits．
③There stands a big tree in front of the classroom．
