Period Three Grammar & Writing
语法精析
一、简单句的五种基本类型
(一)主语＋不及物动词(S＋V)
不能直接加宾语的动词叫做不及物动词。

例如：
The baby laughs.
The children are swimming.
(二)主语＋及物动词＋宾语(S＋V＋O)
后面跟宾语意思才完整的动词是及物动词。

名词、代词、动名词、动词不定式都可以做宾语。

例如：
The workers made machines.
The students are cleaning the classroom.
(三)主语＋系动词＋表语(S＋V＋P)
常见的系动词有：get，be，turn，look，smell，taste，sound，become 等。

表语是英语中的一种特殊成分，常跟在连系动词后面。

表语一般由名词或形容词等充当。

例如：
He became angry.
My mother is a teacher.
(四)主语＋及物动词＋间接宾语＋直接宾语(S＋V＋IO＋DO)
有些及物动词可以有两个(双)宾语，指人的宾语叫做间接宾语，指物的宾语叫做直接宾语，合称为双宾语。

如把直接宾语放在间接宾语之前，间接宾语前要加介词to或者for。

1．与介词to连用的动词主要有：give，bring，lend，pass，show，teach，tell，take，send等。

例如：
He gave me a ruler.＝He gave a ruler to me.
2．与介词for连用的动词主要有：buy，cook，do，find，get，leave，
make，play等。

例如：
My mother bought one beautiful birthday present for me.＝My mother bought me a beautiful birthday present.
注意：如果直接宾语是人称代词时，必须将其置于间接宾语之前。

【误】I need some salt.Pass me it，please.
【正】I need some salt.Pass it to me，please.
(五)主语＋及物动词＋宾语＋宾语补足语(S＋V＋O＋OC)
宾语＋宾语补足语叫做复合宾语，跟宾语补足语的常有以下几类词：
1．后面一般跟不定式作宾语补足语的动词有：ask，get，order，tell，want，wish，allow等。

例如：
Our teacher told us to come early tomorrow.
2．后面一般跟不带to的不定式作宾语补足语的动词有：四“看”：see，watch，look at，notice；三“使役”：let，have，make；二“听”：hear，listen to；一“感觉”：feel等。

例如：
Did you see him come in?
