SV(主+谓): Subject(主语)+Verb(谓语)
这种句型中的动词大多是不及物动词
具体每个动词后究竟加什么介词就得联系动词短语了
如:listen to,look at….)，不及物动词常见的有：appear,apologize,arrive,come,die,disappear,exist,fall,happen,rise……
例句:：The students work very hard.学生们学习很努力。
She apologized to me again. 她再次向我道歉。
The accident happened yesterday evening.事故是昨天晚上发生的。
语法体系之简单句:
1.主谓结构S➕VI
He arrived in the morning.
China belongs to the third world country.
2.主系表结构S➕V➕Predictive(主谓补结构SVC,V为系动词linking v,C为compliment,补充说明S的属性，状态，不能拿掉。)
He seems interested in the book.
The teacher became a singer.
3.主谓宾结构S➕V➕O
We usually play basketball in the morning.
Tom got a promotion from his supervisor(上级)
4.主谓双宾结构S➕V➕IO➕DO
Chris gave his students a grammar lesson.
Chris brought the stray cat(流浪猫) a lot of food.
5.主谓宾宾补结构S➕V➕O➕C
Everyone thought him an idiot.
I find it difficult to believe.
The whole town wanted the outlaw(不法分子，亡命之徒) dead.
另外两种SVA和SVOA一般是状语从句，因为adverb是副词，状语从句也可以说是副词性从句，以下分别举例
1.SVA
He stood at the corner.(地点状语)
2.SVOP
They greeted me in a friendly way.(方式状语)
