1.4 SV（主语+动词）和SVO（主语+动词+宾语）结构
1） 及物动词（Transitive Verb）和不及物动词 （Intransitive Verb）
及物动词的特点是必须跟宾语，不及物动词的特点是不跟宾语或着不能直接跟宾语。英语中有些动词只能用作及物动词，如：enjoy, ignore, complete等；也有些动词只能用作不及物动词，如：arrive, struggle ,vanish等；但多数动词既可以用作及物动词也可以用作不及物动词，例如：
Suddenly the procession stopped.
------------SV结构，stop为不及物动词
The police stopped the procession.
------------SVO结构，stop为及物动词
附： 几个词形相似容易混淆的及物动词和不及物动词lay/lie ,raise/rise ,shine/shine,列表如下：
       vt       vi
lay(laid,laid,laying)放、置 lie (lay,lain,lying)躺
raise(raised,raised,raising-------------抬高 rise(rose,risen,rising) -------------升高
shine(shined,shined,shining)-------------使……光亮 shine(shone,shone,shining) -------------发光亮
2） SVA和SVOA结构（A指，adverbial,状语）
在某些情况下，上述SVA和SVOA结构必须跟有状语意义才算完整，例如：
a--The sun has set .
a’--The sun has set in the west.
b--Did you play basketball?
b’--Did you play basketball after class?
1.4 SVOiOd(主语+动词+间宾+直宾)
1） SVOiOd结构的语序
a) 一般应是， S+V+Oi+Od，间接宾语后移时必须在他前面加上to, for等介词，例如：
Ann gave a beautiful doll to her daughter.
Ann made a beautiful doll for her daughter.
b) 直接宾语为代词时必须紧跟在动词后面；如果直接宾语和间接宾语都是代词，直接宾语一般放在前面。例如：
正确：The mother bought it for the girl 。
错误：The mother bought the girl it 。joozone.com
