※ 引述《yuqian1102 (肉丸)》之銘言：
: 清大102語概
: 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.
: 請問大家
: 要怎麼分d-structure和s-structure呢?
: 一個是變形前一個是變形後嗎?
: 祈使句有變形過嗎?
: 如果可以的話可以告訴我怎麼解這題嗎?
SS是移動後的表層結構而DS就是移動前的深層結構。
舉個例子：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
至於第二題..照上面的說法自己先想想囉。
