請問 能告訴我while的用法嗎?

Question

當名詞以及連接詞的用法(最好可以附加句子) 能否給一些一常會用的句子 用法?

Answer 1

當連接詞
A. 當...
1, Strike the iron while it becomes red.
鐵一變紅,你一定要立刻打下去(打鐵要趁熱),時間是指當下時間
2. Strike the iron when it comes red.
你看到鐵變紅時,就可以打了 (when這裡是條件句,在以下條件出現時(鐵變紅時),你才/可以打鐵--->非只當下時間
B. 然而
John likes music while Helen likes dancing
While VS When

簡單的說,when的時空背景比較長/大,while則比較短,翻做在....的"當下",所以很長皆進行式用
e.g. When I grower older, I hope I can become a teacher. (grower older時空背景比較長)
While Mary was playing tennis, she stepped down an ant accidentally.
你就不能說
When Mary was playing tennis, she ~
或
When Mary played tennis, she ~Ex : He was hitting his girlfriend when she yelled at him.
這句話是錯的
正確應為 : He usually/always/often/sometimes hit his girlfriend when she yelled at him.When 有whenever的味道,在他(每次)yell at him的時候(這時空背景很長),他(總是/常常/...)打他女友在給個更清楚的例句

當名詞
中文解釋為: 一會兒
片語 : 一會兒: for a while = for awhile
有時候 once in a while

Answer 2

當連接詞
A. 當...
B. 然而
C. 所以
D. 換句話說
E. 自己想想
