一、单个的分词修饰名词时，可前置也可后置，通常后置the region studied,the studied region

二、一个或两个介词的短语修饰名词时，通常后置

三、常考的最长的词序
the + 最高级+adv+(分词+adj)+noun.+noun.
~~~~~~~~~这两个前后不确定
the oldest continuously occupied permnant settlement

四、动词短语为完成时或被动式，修饰动词短语的adv夹在中间
have already done
be well done
have not yet rach
be made originally from
be come chiefly from
如果动词短语中有个介词，副词应当放在介词前

五、以分词为中心的合成形容词，应将分词置于词尾eating plant animals应改为plant-eating animals
同样的还有：warm-blooded animals
bridge-built material
cup-shaped sculpture
*选项中的合成形容词便是答案

六、more still abundant 错
more修饰adj，adv时　应紧接在adj/adv的前面
more abundant
only, more than, less than修饰数量名词时，应紧接在数量名词前
The bridge is only three feet long.

七、主系表结构
当谓语动词为系动词时，便是主系表结构
主＋系＋表 　　　　对
主＋表＋系　　　　 错
表＋系＋主　　　　 对（倒装句中）
to stay warm...
rest motionless
remain committed to
became associated with

常考的系动词有：　
rest, stay, remain, mantain, lie, exist, be, become, turn, get
以及感观动词：look, appear, seem, feel, sound, taste
*　appear, seem 可接不定式：appear to do; seem to do
