※ 引述《yuqian1102 (肉丸)》之铭言：
: 清大102语概
: Imperatives in English like (a-c) below do not include YOU as its subject.
: (a) Love yourself.
: (b) Mind your own business.
: (c) Pass the salt, won't you?
: Please answer the following questions:
: A. Are the sentences in (a-c)
: deep structures or surface structures? Why?
: B. Should the imperative sentences include a YOU subject
: in its deep structure? Why or why not? Please explain.
: 请问大家
: 要怎么分d-structure和s-structure呢?
: 一个是变形前一个是变形后吗?
: 祈使句有变形过吗?
: 如果可以的话可以告诉我怎么解这题吗?
SS是移动后的表层结构而DS就是移动前的深层结构。
举个例子：What do you want?
DS: you want what
do-support: do you want what
WH-movement: what do you want
SS: What do you want
至于第二题..照上面的说法自己先想想囉。
