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 如：
the oldest continuously occupied permanent 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 reached
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
